====== Universal Dependencies – UD ======

[[https://universaldependencies.org|Universal Dependencies]] is a an open international project aiming at linguistic annotation consistent across different languages. Some recent versions of the [[en:cnk:intercorp|InterCorp]] parallel corpus ([[en:cnk:intercorp:verze13ud|13ud]] and [[en:cnk:intercorp:verze16ud|16ud]]) have been annotated in terms of morphological categories, syntactic functions and syntactic structure following the UD guidelines and using the tools developed within the UD project.

General guidelines for annotation are provided on the UD project website ([[https://universaldependencies.org/guidelines.html|UD Guidelines]]), including a detailed description of:
  * word types ([[https://universaldependencies.org/u/pos/index.html|Universal POS tags]])
  * morphological categories ([[https://universaldependencies.org/u/feat/index.html|Universal features]])
  * syntactic functions ([[https://universaldependencies.org/u/dep/index.html|Universal Dependency Relations]])

Key specifics of the UD annotation as used in InterCorp:
  * In other releases of InterCorp, word class and morphological categories of a word are specified as the value of the ''tag'' attribute. In the UD annotation, these language-specific tags are retained for most languages, in the ''xpos'' attribute. However, the UD **word class** and **morphological categories**, denoted uniformly for all languages, are listed separately as values of the ''upos'' and ''feats'' attributes (see below [[en:pojmy:ud#parts_of_speech|Parts of speech]], and [[en:pojmy:ud#other_categories|Other categories]], respectively). Frequently used morphological categories from the ''feats'' list have been promoted to the status of regular attributes at the same level as ''upos''. This applies, for example, to morphological case, number, gender or person (''case'', ''number'', ''gender'', ''person''). 
  * For use in KonText, **fused forms** or //aggregates//, ie word forms composed of two or even three syntactic words, were modified as divided tokens. In English it concerns, for example, the forms //isn't// or //cannot//. For more details see [[en:pojmy:ud#multi-part_tokens|Multi-part tokens]] below.
  * Each word is assigned its **syntactic function** (''deprel'' – see [[en:pojmy:ud#syntactic_functions|Syntactic functions]]) and its syntactic governor in the dependency tree (''head''). To facilitate orientation in the syntactic structure, each word is also annotated with references to important properties of its head (lemma, part of speech and morphological categories), see [[en:pojmy:ud#references_to_syntactic_heads|References to syntactic head]]. If a content word occurs with a **function word** (eg. preposition, auxiliary verb, subordinate conjunction, determiner), the content word includes some properties of the function word (see [[en:pojmy:ud#references_to_function_words|References to function words]]).
  * **Annotations between languages differ** in the number of categorial attributes and in links to function words, see [[en:pojmy:ud#description_of_the_list_of_attributes|Description of the list of attributes]] below.
  * KonText supports queries by word class and other morphological categories using the **''Insert tag''** function, which inserts a UD POS (''upos'') and any category from the ''feats'' list into the query. The ''Insert tag'' feature is available for all linguistically annotated languages.
===== Morphological annotation =====

==== Parts of speech ====

  * In UD, part of speech is listed **separately from other categories** as the value of the **''upos''** attribute. 
  * Parts of speech given in ''upos'' are the **same for all languages**.
  * In addition to ''upos'', most languages provide a **language-specific morphological tag**, as the value of the **''xpos''** attribute. The ''xpos'' value is usually identical to a corresponding tag from the other, non-UD-based versions of InterCorp.

==== Other categories ====

  * Other categories are embedded under the **''feats''** attribute. Their choice and values are determined by part of speech and language. 
  * Each category is listed as a "<category name>=<category value>" pair, e.g. ''Number=Sg''.
  * Identical or comparable morphological categories and their values are called the same in all languages. 
  * A list of such pairs is the value of the ''feats'' attribute.
  * Categories in the ''feats'' attribute are separated by "|", e.g. the Russian form //школы// /'ʂkolɨ/ 'school' in genitive singular is marked as ''feats=%%"Animacy=Inan|Case=Gen|Gender=Fem|Number=Sing"%%''. 
  * In an advanced query using the CQL query language each category can be specified separately: the Czech form //moře// 'sea' is one of the answers to the query ''%%[upos="NOUN" & feats="Number=Sing"]%%''.  The Russian form is found following the query ''[upos=%%"NOUN"%% & feats=%%"Gender=Fem"%% & feats=%%"Case=Gen"%%]''. The order of categories in the query is irrelevant. 
  * The value of ''feats'' can also be treated as a string of characters using regular expressions, e.g. ''[upos=%%"NOUN"%% & feats=%%".*Case=Gen.*Gender=Fem.*"%%]''. Here the order of categories in the query should correspond to their order in the corpus. The result is the same in both cases.
  * Some of the categories in ''feats'' are listed also outside the list as **categorial attributes** at the same level as ''upos''. As a result, a query for a singular noun can be simply as follows: ''%%[upos="NOUN" & number="Sing"]%%''. Similarly, the query  for the Russian form ''[upos=%%"NOUN"%% & %%gender="Fem"%% & %%case="Gen"%%]'' gives the same result as the two queries above. Categorial attributes can be also used to generate frequency lists.((Note that for technical reasons the names of the categorial attributes are all in lower case, including names such as ''VerbForm'' (in ''feats''), rendered as ''verb_form'', or ''NumType'', rendered as ''num_type''. The attribute values, such as ''Fem'', retain the initial upper case character, but are enclosed in double quotes, like other attribute values outside ''feats''.))  Such attributes appear on the <fc #f4a460>light brown</fc> background in {{cnk:intercorp:ud_ic_attributes.pdf|Attribute list by language}} or in KonText in the lower part of the table shown in ''View'' / ''Corpus-specific settings...'' .

==== Multi-part tokens ====

  * Some tokens, in the UD parlance called **fused words**, or **aggregates** in some Czech corpus-related literature, consist of multiple parts. These parts correspond to different nodes in the syntactic structure. In English, such tokens represent **contractions**, consisting of a verb and the negative particle such as //isn't// or //cannot//. 
  * The orthographic form of these words is preserved in the corpus, the individual parts are separated only in the annotation - e.g. in the value of the ''lemma'' attribute, with the "|" sign as the separator. It is therefore possible to search for them like other words, by typing the full form into the search box in a simple query (e.g. //ses// in Czech, //can't// in English or //byłbym// in Polish), or in the advanced query using the CQL search language give the same strings as the value of the **''word''** attribute .
  * In some languages, including English and Czech, a part of the fused token has a different form when occurring in a different context as an orthographically separate word. E.g. //n't//, a part of //isn't//, corresponds to //not//, the Czech auxiliary clitic //s//, a part of //ses//, corresponds to //jsi//. Both variants are represented in the annotation: the **''iword''** attribute shows the original form ''is|n't'' or ''se|s'', while the **''sword''** attribute shows the unabbreviated, "reconstructed" version: ''is|not'' or ''se|jsi''.((Aggregates are present in the following languages: ar, ca, cs, de, el, en, es, fi, fr, he, it, pl, pt, tr and uk. A list of all aggregates for a given language is displayed as the frequency distribution of word forms following the query %%[sword = ".|.+"]%%.))
  * In addition to the English tokens //isn't// (''is|n't'' – ''is|not'') or //cannot// (''can|not''),((The first form, preceding the dash, is the original form, i.e. the value of the ''iword'' attribute, the second form, after the dash, is the reconstructed form, i.e. the value of the ''sword'' attribute. If a parenthesis includes just one form, the two options are identical, or the given language does not provide reconstructed forms.)) in Czech there are tokens such as //abychom// (''a|bychom'' – ''aby|bychom''), //bylas// (''byla|s'' – ''byla|jsi'') or //oč// (''o|č'' – ''o|co''); in German //zur// (''zu|r'' – ''zu|der'') or //am// (''a|m'' – ''an|dem''); in Polish //miałam// (''miała|m''), //żebyś// (''że|by|ś'') or //chciałbym// (''chciał|by|m''); in French //des// (''de|s'' – ''de|les''), //aux// (''au|x'' – ''à|les'') or //auquel// (''au|quel'' – ''à|lequel'').

===== Syntactic annotation =====

==== Syntactic functions ====

  * Each token specifies its syntactic function, i.e. dependency relation (''deprel'') and a reference to its syntactic governor (''head'').
  * The table below distinguishes four types of syntactic functions by different typeface:
     * Common deprels are listed in **bold**.
     * Deprels of function words are listed in //**bold italics**//.
     * Deprels for representing coordination and similar phenomena in the dependency structure or for a technical purpose are set in //italics//.
     * Deprels not used in English are listed in <fc #c0c0c0>in gray</fc>.
  * In some languages, some deprels may have **subtypes**. The subtype name follows the colon after the deprel name, e.g. ''acl:relcl'' indicates an attribute expressed by a relative clause. The list below contains only subtypes relevant to English and represented in the corpus. Functions with subtypes for all languages are listed at [[https://universaldependencies.org/u/dep/index.html|Universal Dependency Relations]].
  * When querying a deprel that may have a subtype, a possible subtype should be taken into account. For example, to find all words with the deprel ''acl'', whether or not the deprel has a subtype, use the expression ''%%deprel="acl.*"%%'' instead of ''%%deprel="acl"%%''. To find all auxiliary verbs, use the expression ''%%deprel="aux.*"%%'' instead of ''%%deprel="aux"%%''. To find all subjects, use the expression ''%%deprel="nsubj.*"%%''.
  * When a queried deprel targets a **coordinated structure**, only the first conjunct is found. The second and subsequent conjuncts are marked as ''%%deprel="conj"%%''. The syntactic function of the entire coordination is thus specified by the ''deprel'' attribute of the first conjunct, the head of all other conjuncts. To query the "true" deprel of a non-initial conjunct (''%%deprel="conj"%%''), use the ''p_deprel'' attribute. See [[en:pojmy:ud#coordination|Coordination]] below for details.

==== References to syntactic heads ====

  * In addition to the pointer to its head (''head'' as the word ID of the head, i.e. its word order position within the sentence, or ''parent'' as its position relative to the given word), some other attributes of the head are listed for each token: lemma (''p_lemma''), POS (''p_upos''), morphological category (''p_feats''), and syntactic function (''p_deprel'').
  * A token may also have attributes that specify the properties of a function word that depends on the token. For example, the lemma of a preposition is shown by the attribute ''case_lemma'', morphological categories of an auxiliary by ''aux_feats'', morphological categories of a copula by ''cop_feats'', part of speech of a determiner by ''det_upos'', lemma of a marker by ''mark_lemma''.
  * Similar means of representing syntactic structure are used by other syntactically annotated corpora available in the KonText browser (e.g. ''syn2020'').

==== References to function words ==== 

  * According to UD, function words include auxiliary verbs, adpositions, subordinating conjunctions, conjunctions, determiners, and quantifiers.
  * Function words depend on the corresponding content words.  
  * Types of function words are specified by their syntactic function, i.e. by the value of the ''deprel'' attribute: ''aux'' (auxiliaries), ''case'' (prepositions), ''mark'' (markers), ''cop'' (copula), ''det'' (determiners), and ''clf'' (classifiers).  
  * For each function word the content word governor may include the function word's ''lemma'', ''upos'', ''feats'' and a more detailed specification of ''type'', e.g. ''%%aux_type="pass"%%'' (see [[https://universaldependencies.org/cs/dep/aux-pass.html|passive auxiliary]]), or ''%%det_type="numgov"%%'' (see [[https://universaldependencies.org/cs/dep/det-numgov.html|pronominal quantifier governing the case of the noun]]). 
  * The names of the corresponding content word attributes consist of the function word's ''deprel'' and attribute. For example, ''case_lemma'' specifies the lemma of the noun or pronoun's preposition, the ''aux_feats'' attribute of a content verb specifies morphological categories of its auxiliary.
  * A single content word can govern multiple function words, e.g. three for the passive present perfect conditional (//she would have been **pleased**//). The values of all the auxiliary words, separated by "''|''", then appear in the appropriate attribute. The ''feats'' attribute values from multiple auxiliary verbs dependent on a single meaning are combined into a single value where some categories, such as verb form specifications, may be repeated because they come from more than one form. For example, in the sentence //who would have **guessed** that//, the ''aux_feats'' of the content verb //guessed// are composed of the feats of the auxiliary verbs //would// (''%%Mood=Ind|Person=3|Tense=Past|VerbForm=Fin%%'') and //have// (''%%VerbForm=Inf%%'').

==== Coordination ====

  * The first conjunct depends on the governor of the entire coordination. Its syntactic function determines the syntactic function of the whole coordination. 
  * The second and subsequent conjuncts always depend on the first conjunct. Their syntactic function is specified as ''conj''.
  * Conjunctions depend on the following conjunct. Their syntactic function is ''cc''.
  * A reference to the so-called effective head is used to identify the head regardless of whether the token is a conjunct or not, or whether it is in the initial or non-initial conjunct: the ''e_id'' attribute refers to its identifier (the sequence number of the token representing the head within the sentence), the ''eparent'' attribute to its position  relative to the token. 
  * In InterCorp [[en:cnk:intercorp:verze16ud|release 16ud]], there is an additional ''e_deprel'' attribute whose value equals ''deprel'' of the given token, except when the token is a non-initial conjunct, i.e. when its ''deprel'' equals ''conj''. Then the value of ''e_deprel'' equals the value of ''p_deprel'', i.e. shows the syntactic function of the whole coordination.
  * The ''e_deprel'' attribute has the same value as ''p_deprel'' also when the ''deprel'' attribute equals ''fixed'', ''flat'', ''compound'' or ''list''. Tokens within such constructions can also be found using the syntactic function of the whole construction, i.e. the ''e_deprel'' attribute.   
  * To find all words with a certain syntactic function, including those that are part of a coordination, in InterCorp [[en:cnk:intercorp:verze13ud|release 13ud]], where the ''e_deprel'' attribute is not available, the solution is to use the ''p_deprel'' attribute. This attribute shows the syntactic function of the token's head. For example, a query for all direct objects, including coordinated ones, can be formulated using the disjunction operator (%%|%%) as follows: ''%%[deprel="obj" | deprel="conj" & p_deprel="obj"]%%''.

==== Corpus Search ====

=== Basic query ===

  * A basic query for a word form or phrase is entered in the same way as in previous releases of InterCorp.((In a basic query, it is no longer necessary in some languages to separate parts of the aggregate with a space, eg //był//, //by//, and  //m// of the Polish agglutinated form //byłbym // or //is// and //n't// of the English contraction //isn't//, even in a longer expression (//aren't I//). However, a basic query for //is// or //n't// will not show concordances including the form //isn't//.))

=== Query for a lemma and a morphological tag ===

  * As in previous releases of InterCorp, a lemma and a morphological tag can be entered in an advanced query. For most linguistically annotated languages (except be, da, en, fr, hu, no and ru) it is possible to enter a tag from a language-specific set (national tagset), usually identical to the set used in the previous releases of InterCorp for that language. Just use the ''xpos'' attribute instead of the ''tag'' attribute. E.g. the query on feminine nouns in the vocative singular in Czech can be entered as follows: %%[xpos = "NNFS5.*"]%%.
  * According to UD, part of speech and morphological categories are listed separately as values of the attributes ''upos'' and ''feats'', respectively. Their values can be entered using the ''Insert tag'' function. 
  * Parts of speech (''upos'') are the same for all languages. E.g. a query for proper names without using the ''Insert tag'' function can be specified as follows: %%[upos = "PROPN"]%%.
  * Other morphological categories are listed under the ''feats'' attribute. Some of them are available separately under categorial attributes. For details see [[en:pojmy:ud#other_categories | Other categories]] above. 

=== Query for a part of speech and morphological categories using the menu ===

   * When entering an advanced query, you can use the ''Insert tag'' function, which lets you select the POS and/or the values of the relevant categories (properties) from the ''feats'' list in all linguistically annotated languages. The offer of properties for a given POS is determined by their actual occurrence in the corpus, so the list may reflect incorrect combinations.

=== Query for a syntactic function ===

   * Syntactic function is specified for each token as the value of the ''deprel'' attribute (see [[en:pojmy:ud#syntactic_functions | Syntactic functions ]] above.
   * E.g. a query to show the occurrences of the verb //run// in the function of the governor of an adnominal clause, is entered as %%[lemma="run" & deprel="acl"]%%. Results include examples such as //Everyone of the rabbits was seized by the instinct **to __run__ away**, to go underground. Some people have the idea that rabbits spend a good deal of their time **__running__ away from foxes**.//


==== Query results ====

=== Formatted text ===

  * After clicking on the keyword and ''Formatted text'' in the context box header, a concordance will appear along with the nearest context in a form that is close to the typography of the original text. For example, there are no spaces between the end of a word and punctuation, and paragraphs are separated by a blank line.

=== Syntactic structure display ===

  * After clicking on the syntax tree icon at the beginning of each concordance line, the syntactic structure of the sentence is displayed. For each node, the word form, POS and syntactic function of the word relative to the given token are given. After clicking on the node, other annotation will appear, especially the lemma of the form.
  * Multi-part tokens (aggregates) are divided into multiple nodes and the word form then corresponds to the relevant part of the token (the ''iword'' attribute). After clicking on such a node, in addition to the lemma of the given part of the multi-word token, its full form (as a separate word, the ''sword'' attribute) and the word form of the entire token (''word'') also appear.
  * In the text line above the structure and in the structure, under the cursor the relevant strings and nodes are highlighted in parallel.

==== Examples of queries ====

The queries mainly show the possibilities of using syntactic functions in connection with parts of speech and morphological categories, but also include references to syntactis heads and dependent auxiliaries. Most of the queries concern English, but they are also applicable to other languages, although the specific language may require some modifications to the query. Queries can be entered in one language, or in two or more languages in parallel.

=== Who are the most likely singers ===

<code>[deprel="nsubj" & p_lemma="sing"]</code> 

  * [[https://www.korpus.cz/kontext/view?q=~CKymagKES4Gm|This query]] finds subjects of the verb //sing//. One of the results is the sentence //The **birds** sing sweetly in these trees.//
  * The most frequent lexemes filling the subject slot of //sing// can be found from the list of keyword lemmas (in the KonText menu:  ''%%Frequency / Lemmas%%'').

=== What birds do most often ===

<code>[deprel="nsubj" & lemma="bird"]</code>

  * [[https://www.korpus.cz/kontext/view?q=~YqKMIaOKMUQ0|This query]] finds occurrences of //bird//(//s//) as the subject. The query finds e.g. the sentence //A few **birds** flew off in disgust.// 
  * The verbs governing the subject can be listed using in the frequency distribution according to the ''p_lemma'' attribute (in the KonText menu: ''%%Frequency / Custom... / Attribute: p_lemma%%'').

=== Nouns following a specific preposition ===

<code>[case_lemma="about" & case="Acc"]</code>

  * [[https://www.korpus.cz/kontext/view?q=~eOAK2og4uUoQ|This query]] finds accusative nominals, i.e. pronominal forms such as //her// or //themselves//, preceded by the preposition //about//. In English, only such forms are annotated as ''%%case="Acc"%%''. For nouns, the ''case'' attribute is not specified.((In the current release, only very few occurrences of personal pronouns in the subject position (such as //she//) are annotated as ''%%case="Nom"%%''.)) 
  * To extend the search to all nouns, drop ''%%case="Acc"%%''. The query ''%%[case_lemma="about"]%%'' finds all nominals governing the preposition //about//, i.e. all nominals in prepositional phrases beginning with this preposition, including sentences such as //‘May I ask **what** this is all about, sir?’ said Bigwig.//
  * The governing verbs can be listed using frequency distribution according to the ''p_lemma'' attribute (in the KonText menu: ''%%Frequency / Custom... / Attribute: p_lemma%%'').
  * The query does not assume any specific word order, the noun could also precede the preposition, which would indeed be highly unlikely.


=== Verbs taking an indirect object ===

<code>[deprel="iobj"]</code>

  * [[https://www.korpus.cz/kontext/view?q=~MwKKiaMYIgcg|This query]] finds indirect objects.
  * The lemma of the indirect object's head can be listed using frequency distribution according to the attribute ''p_lemma''.
  * Note that in UD, dative complements in languages such as German or Czech are non-core dependents. As such, they should be labelled as ''%%deprel="obl"%%'' or (preferably but not obligatorily) ''%%deprel="obl:arg"%%''. For more details see [[https://universaldependencies.org/u/overview/syntax.html#core-arguments-vs-oblique-modifiers|Core Arguments vs. Oblique Modifiers]].


=== Direct or indirect objects, also as conjuncts ===

<code>[e_deprel="i?obj"]</code>

  * [[https://www.korpus.cz/kontext/view?q=~ROysAM6KwymO|This query]] finds direct or indirect objects, even as non-initial conjuncts, e.g. in the sentence //In Trump, they have found a shameless **frontman** and TV **personality** who will do their bidding.//
  * Note that for coordinated constituents, a separate concordance is shown for each conjunct.

<code>[deprel="i?obj" | deprel="conj" & p_deprel="i?obj"]</code>

  * [[https://www.korpus.cz/kontext/view?q=~TwkkE2u668ya|This query]] should be used in 13ud, where the ''e_deprel'' attribute is not available.
  * Either the keyword's ''deprel'' denotes the direct or indirect object (''%%deprel="i?obj"%%'', or -- equivalently -- ''%%deprel="obj|iobj"%%''), or the keyword's ''deprel'' is ''conj'' (''%%deprel="conj"%%'') and depends on a direct or indirect object (''%%p_deprel="i?obj"%%''), i.e. it is the non-initial conjunct in a coordinated constituent functioning as direct or indirect object.
  * In 16ud we get the same result using the ''e_deprel'' attribute in a simpler query:

=== Proper nouns as subjects, also as conjuncts ===

<code>[deprel="nsubj" & upos="PROPN" | deprel="conj" & p_deprel="nsubj" & upos="PROPN"]</code> 

  * [[https://www.korpus.cz/kontext/view?q=~cuIC4msKMsAW|This query]] finds proper nouns as subjects, including non-initial conjuncts.
  * Concordances include sentences such as //And what does **Crump** say?// or //“I never even saw her,” said **Pat**.//
  * In 16ud, the same query can be simplified using the ''e_deprel'' attribute:

<code>[e_deprel="nsubj" & upos="PROPN"]</code> 

=== Gerunds preceded by "with" as the marker ===

<code>[verb_form="Ger" & mark_lemma="with"]</code>

  * [[https://www.korpus.cz/kontext/view?q=~Emo6O4KwIC8W|This query]] finds  ing-forms, heading non-finite clauses and preceded by //with//, as in //With the Italian front **collapsing**, they need him elsewhere.//((The automatic annotation of these sentences is not 100% consistent. Sometimes //with// is tagged as a preposition and attached to the subject of the non-finite clause, as in //She ran off, with the toy **spider** scuttling obediently after her.//))
  * The lemma of the gerund's head (often a finite verb) can be listed using frequency distribution according to the attribute ''p_lemma''.
  * Its part of speech and other categories can be listed using frequency distribution according to the attributes ''p_upos'' and  ''p_feats''.

=== Verbs of sensing followed by an object and an infinitive ===

<code>1:[lemma="feel|sense|perceive"] []* 2:[deprel="obj"] []* 3:[verb_form="Inf" & deprel="xcomp"] & 2.head=1.id & 3.head=1.id within <s/></code>

  * [[https://www.korpus.cz/kontext/view?q=~OgQaiMo4QMac|This query]] finds sentences with verbs //feel//, //sense// or //perceive// governing an object and an infinitive ''xcomp''. There can be any number of other words between these tokens, but only within a single sentence, as in //Karras **felt** the pulse **rate** suddenly **drop**.//
  * The query uses two [[https://www.sketchengine.eu/documentation/cql-global-conditions/|global conditions]] to make sure that the object and the infinitive depend on the sending verb, i.e. that the two dependents point to the ID of the sensing verb is its head (syntactic governor).


=== Past conditional passive in Czech ===

<code>[voice="Pass" & aux_feats="Mood=Cnd" & aux_feats=".*Tense=Past.*Tense=Past.*"]</code>

  * [[https://www.korpus.cz/kontext/view?q=~uSIiCIoGCi6g|This query]] finds sentences including a verb in the passive voice and past conditional mood, e.g. //... aféra by byla bývala ututlána.// '... the scandal would have been hushed up.'
  * The form of the content verb used in the periphrastic passive has an adjectival lemma, e.g. //ututlaný// 'hushed', the adjectival POS ''upos=ADJ'' and its morphological categories include the features''%%feats="...Variant=Short|VerbForm=Part|Voice=Pass"%%''. On the other hand, reflexive passive, e.g. //oholil se// '[he] shaved himself', is annotated as ''%%feats="...Voice=Act"%%''.
  * According to the UD guidelines, function words are immediate dependents on the relevant content word. In InterCorp 13ud, values of the ''feats'' attribute specified in multiple function words dependent on a single content word governor are concatenated into a single value. If so, categories such as Tense can occur more than once in the value of such a ''feats'' attribute, because it originates in two or more auxiliaries, as in our example from //byla// '[she] was' and //bývala// '[she] used to be'. 
  * This double occurrence is what the query uses to target the presence of two auxiliaries. If a query looking for passive voice verbs would mention only ''%%[aux_feats="Tense=Past"]%%'', the result would include also present conditional forms, where the l-participle (the ''%%"Tense=Past"%%'' form) occurs just once as the passive auxiliary (//... aféra by byla ututlána.// 'the scandle would be hushed up.').


=== Past conditional passive in English ===

<code>[feats="VerbForm=Part" & aux_feats=".*Tense=Past.*VerbForm=Inf.*Tense=Past.*"]</code>

  * [[https://www.korpus.cz/kontext/view?q=~7okkiSwCoOaq|This query]] finds sentences such as //He would not have been **annihilated** but enslaved, and Barad-dûr would not have been **destroyed** but occupied.//


=== Continuous perfect ===

<code>[feats="VerbForm=Ger" & aux_feats="VerbForm=Fin" & aux_feats="VerbForm=Part"]</code>

  * [[https://www.korpus.cz/kontext/view?q=~pIOs8ciQiOiW|This query]] finds sentences including continuous perfect forms (both present and past), e.g. //... has been constantly increasing in velocity//.

=== Passive of first person singular continuous  ===

<code>[aux_lemma="be" & aux_feats="Person=1" & aux_feats="Number=Sing" & aux_feats="VerbForm=Ger" & feats="VerbForm=Part"]</code>

  * [[https://www.korpus.cz/kontext/view?q=~8OWi2MEwMmWs|This query]] finds passive participles preceded by the continuous form of the //be// auxiliary in first person singular, as in //I’m not exactly being **given** much help.//.
  * Note that the query succedes only when there are two distinct auxiliaries dependent on the content verb participle, namely a finite form ''%%aux_feats="Person=1" & aux_feats="Number=Sing"%%'' and an //ing//-form ''%%aux_feats="VerbForm=Ger"%%'', because a single form cannot be a gerund and in the first person at the same time. 

=== Past perfect ===

<code>[feats="VerbForm=Part" & aux_lemma="have" & aux_lemma!="be|will|can|may|must" & aux_feats="Mood=Ind" & aux_feats="Tense=Past"]</code>

  * [[https://www.korpus.cz/kontext/view?q=~ECKYEQqWwSim|This query]] finds sentences including a verb in past perfect, e.g. //Yet the streets were by then safer than they had ever **been**//, but also //It was as if the devil had suddenly **re-emerged** in the roar of the flames.//
  * The specification ''%%aux_lemma!="be|will|can|may|must"%%'' is necessary to exclude cases where //have// is not the only auxiliary verb dependent on the participle, as in //you would have **thought** he had been **bred** up in the lyceum//. On the other hand, //be// should not be included in the stoplist if passive past perfect (the last clause in the example) is also expected in in the results.  




===== Description of the list of attributes =====

  * In {{cnk:intercorp:ud_ic_attributes.pdf | Attribute list by language in 13ud}} or {{cnk:intercorp:ud_ic16ud_attributes.pdf | Attribute list by language in 16ud}} all attributes used in the specific version are listed.
  * Columns indicate whether the attribute is used for the language specified by the abbreviation in the header.
  * Attributes are divided into four categories, distinguished by background color.
  * For brevity, only linguistically annotated languages are included. E.g. the list for 16ud omits 14 languages denoted by the language codes bn, br, bs, eo, hs, ka, mk, ml, ms, rn, si, sq, th and tl. These languages can be queried Only the ''word'' and ''lc'' attributes can be used to query these languages.

==== Basic attributes ====

  * These 12 attributes are on the <fc #dda0dd>light purple</fc> background.
  * They consist of the following items: word form, lemma, part of speech, morphological categories, token order in a sentence, head reference and syntactic function.
  * They are usually taken directly from the output of the tool [[https://ufal.mff.cuni.cz/udpipe|UDPipe]]. The format of the output is [[https://universaldependencies.org/format.html|CoNLL-U]].
  * There are two added attributes: ''lc'' and ''lc_lemma'', which repeat word form and lemma without any capital letters.
  * For languages with multipart tokens (aggregates), there are also two additional ''sword'' and ''iword'' attributes.
  * The ''sword'' attribute includes the word form of the aggregate split by the "|" character into parts corresponding to syntactic words as they occur outside an aggregate, e.g. for //nač// and //abychom// the values of ''sword'' equal ''na|co'' and ''aby|bychom''.
  * The ''iword'' attribute splits the aggregate into parts without any modification, for the tokens //nač// and //abychom// the values of ''iword'' egual ''na|č'' and ''a|bychom''.
 
==== Structural attributes ====

  * These attributes are on the <fc #6495ed>light blue</fc> background.
  * They extend the reference to the token's syntactic governor (''head'') by additional attributes, making it easier to identify the head and its properties.
  * All attributes of this type are avaliable for all languages.

==== Function word attributes ====

  * These attributes are on the <fc #9acd32>light green</fc> background.
  * They are given within the content word in order to specify the essential properties of the dependent function word.
  * The total number of function word attributes is 20, but no language uses them all.
  * Attributes refer to 6 types of auxiliary words, determined by their syntactic function in relation to the semantic word.
  * For each function word, the lemma, part of speech, morphological categories and subtype of the function word can be specified.
  * An attribute name consists of the name of the function word's syntactic function and the name of its property (attribute).
  * Unused or uninformative attributes are absent for the given language. There are four possible combinations which do not occur in any language.
  * Most languages (35) use the attribute ''case_lemma'' (lemma of apposition, most often prepositions), followed by ''mark_lemma'' (lemma of subordinate conjunctions, in 33 languages).
  * The ''clf_lemma'' (lemma of classifier) attribute only appears in Chinese.
  * If there are several auxiliaries of the same type for a content word, their values are separated by the "|" character.

==== Attributes representing selected categories ====

  * On the <fc #f4a460>light brown</fc> background, there is a selection of 18 attributes from the ''feats'' list.
  * Only Latvian uses them all, while Maltese uses none. In addition to the language type, their presence or absence also depends on the availability of the category in the UD data.

===== Errors and shortcomings of linguistic annotation according to UD =====

   * POS and morphological categories do not match
   * Inconsistencies in the application of the principles of uniform classification of phenomena in all languages
   * Errors and inconsistencies in the given language (e.g. //udělals// as a unitary token)

The quality of annotations in different languages differs mainly in the volume and quality of training data. It is also affected by the method and tool used for annotation.
