===== FicTree: a manually annotated treebank of Czech fiction =====

The FicTree treebank is a syntactically annotated corpus of Czech fiction. It consists of 135,000 words (166,000 tokens).  The lemmatization, the morphologic and syntactic annotation were performed manually.

===== The composition of the FicTree treebank =====

The FicTree treebank consists of eight literary works published in the Czech Republic between 1991 and 2007. The texts in the treebank include six fiction titles, a children’s fiction  book, and a book of memoirs. 
Most of the texts were first published between 1991 and 2007 except one text, published in 1969.
Five texts (80% of all tokens) are original Czech texts, the other three are translations (from German and Slovak).

===== The syntactic annotation of the treebank =====

The FicTree treebank was syntactically annotated according to the guidelines for the analytical layer of the Prague Dependency Treebank - PDT ([[http://ufal.mff.cuni.cz/pdt2.0/doc/manuals/cz/a-layer/html/index.html|PDT 2.0]] with revisions [[http://ufal.mff.cuni.cz/pdt2.5/cs/documentation.html|2.5]] and [[http://ufal.mff.cuni.cz/pdt3.0|3.0]]). The corpus was parsed using two parsers: ([[https://sourceforge.net/projects/mstparser/|MST Parser]] and [[http://www.maltparser.org/|MaltParser]]) trained on the PDT a-layer train data. The results were manually corrected by annotators, then merged. Any differences between the two versions were resolved manually by another annotator.

===== Access to the treebank =====

The FicTree treebank can be accessed in several ways:
  - [[en:cnk:fictree#a_cnc_corpus_in_the_kontext_interface|A CNC corpus in the KonText interface]]: FicTree is available as a [[en:cnk:uvod|CNC corpus]] in the [[en:manualy:kontext:index|KonText]] interface.
  - [[en:cnk:fictree#data_annotated_according_to_pdt_a-layer|Data annotated according to PDT a-layer]]: the data of the FicTree treebank annotated according to the [[http://ufal.mff.cuni.cz/pdt2.0/doc/manuals/cz/a-layer/html/index.html|PDT a-layer guidelines]] are available to download from the [[https://lindat.mff.cuni.cz/repository/xmlui/handle/11234/1-2517|LINDAT/CLARIN]] repository for non-commercial use.
  - [[en:cnk:fictree#data_annotated_in_the_Universal_Dependencies_standard|Data annotated in the Universal Dependencies standard]]: the data of the FicTree treebank annotated according to the [[http://universaldependencies.org/|Universal Dependencies]] standard into which it was automatically converted  (for non-commercial use only).

===== 1. A CNC corpus in the KonText interface =====

The FicTree corpus is available in the same way as other CNC corpora through the [[en:manualy:kontext:index|KonText]] interface.

The corpus annotation is accessible through a wide range of attributes of each token. The morphologic and annotation and lemmatization is available using the attributes [[seznamy:tagy|tag]] and [[en:pojmy:lemma|lemma]], additionally, the information about the POS and nominal case (if applicable) of all tokens is accessible using the attributes **pos** and **case**.

The syntactic annotation of FicTree can be accessed using several positional attributes (the same as in the corpus SYN2015):
  * afun – syntactic function according to the a-layer PDT annotation
  * parent – relative position of the governing token
  * eparent – relative position of the nearest governing content word
  * prep – lemma of a preposition governing the token (if any)
  * p_lemma, p_tag, ep_lemma, ep_tag – tag a lemma of the governing token
  * p_pos, p_case, ep_pos, ep_case – POS and case of the governing token
  * p_afun, ep_afun – syntactic function of the governing token

===== 2. Data annotated according to PDT a-layer =====

The data of the FicTree treebank, annotated according to the PDT a-layer guidelines, are available through the 
[[https://lindat.mff.cuni.cz/repository/xmlui/handle/11234/1-2517|LINDAT/CLARIN]] repository in a ''vertical'' format (tab-separated values), sentence boundaries are marked with empty lines. Each word is written on a single line, followed by five attributes separated by tabulators: **lemma**, **tag**, **ID** (number indicating the position of the token in the sentence), **head** (ID of the governing token) and **afun** (syntactic function according to [[http://ufal.mff.cuni.cz/pdt2.0/doc/manuals/cz/a-layer/html/index.html|PDT]]). The texts are divided into segments of maximum 100 tokens (respecting sentence boundaries), the segments are randomly shuffled. Every such segment constitues a single file, the name of the file refers to the literary work, its prefix indicates the intended partition of the data into train, dev and test data (80% - 10% - 10%).

===== 3. Data annotated in the Universal Dependencies standard =====

The morphological and syntactic annotation according to the UD guidelines was assigned by converting the original PDT annotation. The conversion procedure was designed by Dan Zeman and implemented in [[https://github.com/ufal/treex|Treex]].
The data are available on the [[http://universaldependencies.org/treebanks/cs_fictree/index.html|Universal Dependencies]] webpage. They are in the [[http://universaldependencies.org/format.html|CONLL-U format]]. The original texts are divided into segments of maximum 100 tokens, the segments are shuffled and divided into a train, val and test data set. The FicTree treebank in UD standard is also accessible using the query tool  [[https://lindat.mff.cuni.cz/services/pmltq/|PML-TQ]].
