| [[https://universaldependencies.org|Universal Dependencies]] is a framework for consistent annotation of grammar (parts of speech, morphological features, and syntactic dependencies) across different human languages. Some recent versions of the [[en:cnk:intercorp|InterCorp]] parallel corpus ([[en:cnk:intercorp:verze13ud|13ud]] and [[en:cnk:intercorp:verze13ud|13ud]]) has 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. | [[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. |

| * 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]]). | * 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'').

| * 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. | * 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. | * 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"]%%''. | * 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.
