GeCzLex: Lexicon of Czech and German Anaphoric Connectives
Lucie Poláková | Kateřina Rysová | Magdaléna Rysová | Jiří Mírovský
Proceedings of the 12th Language Resources and Evaluation Conference

We introduce the first version of GeCzLex, an online electronic resource for translation equivalents of Czech and German discourse connectives. The lexicon is one of the outcomes of the research on anaphoricity and long-distance relations in discourse, it contains at present anaphoric connectives (ACs) for Czech and German connectives, and further their possible translations documented in bilingual parallel corpora (not necessarily anaphoric). As a basis, we use two existing monolingual lexicons of connectives: the Lexicon of Czech Discourse Connectives (CzeDLex) and the Lexicon of Discourse Markers (DiMLex) for German, interlink their relevant entries via semantic annotation of the connectives (according to the PDTB 3 sense taxonomy) and statistical information of translation possibilities from the Czech and German parallel data of the InterCorp project. The lexicon is, as far as we know, the first bilingual inventory of connectives with linkage on the level of individual entries, and a first attempt to systematically describe devices engaged in long-distance, non-local discourse coherence. The lexicon is freely available under the Creative Commons License.

CzeDLex 0.6 and its Representation in the PML-TQ
Jiří Mírovský | Lucie Poláková | Pavlína Synková
Proceedings of the 12th Language Resources and Evaluation Conference

CzeDLex is an electronic lexicon of Czech discourse connectives with its data coming from a large treebank annotated with discourse relations. Its new version CzeDLex 0.6 (as compared with the previous version 0.5, which was published in 2017) is significantly larger with respect to manually processed entries. Also, its structure has been modified to allow for primary connectives to appear with multiple entries for a single discourse sense. The lexicon comes in several formats, being both human and machine readable, and is available for searching in PML Tree Query, a user-friendly and powerful search tool for all kinds of linguistically annotated treebanks. The main purpose of this paper/demo is to present the new version of the lexicon and to demonstrate possibilities of mining various types of information from the lexicon using PML Tree Query; we present several examples of search queries over the lexicon data along with their results. The new version of the lexicon, CzeDLex~0.6, is available on-line and was officially released in December 2019 under the Creative Commons License.

EvalD Reference-Less Discourse Evaluation for WMT18
Ondřej Bojar | Jiří Mírovský | Kateřina Rysová | Magdaléna Rysová
Proceedings of the Third Conference on Machine Translation: Shared Task Papers

We present the results of automatic evaluation of discourse in machine translation (MT) outputs using the EVALD tool. EVALD was originally designed and trained to assess the quality of human writing, for native speakers and foreign-language learners. MT has seen a tremendous leap in translation quality at the level of sentences and it is thus interesting to see if the human-level evaluation is becoming relevant.

Introducing EVALD – Software Applications for Automatic Evaluation of Discourse in Czech
Kateřina Rysová | Magdaléna Rysová | Jiří Mírovský | Michal Novák
Proceedings of the International Conference Recent Advances in Natural Language Processing, RANLP 2017

In the paper, we introduce two software applications for automatic evaluation of coherence in Czech texts called EVALD – Evaluator of Discourse. The first one – EVALD 1.0 – evaluates texts written by native speakers of Czech on a five-step scale commonly used at Czech schools (grade 1 is the best, grade 5 is the worst). The second application is EVALD 1.0 for Foreigners assessing texts by non-native speakers of Czech using six-step scale (A1–C2) according to CEFR. Both appli-cations are available online at https://lindat.mff.cuni.cz/services/evald-foreign/.

Coreference in Prague Czech-English Dependency Treebank
Anna Nedoluzhko | Michal Novák | Silvie Cinková | Marie Mikulová | Jiří Mírovský
Proceedings of the Tenth International Conference on Language Resources and Evaluation (LREC'16)

We present coreference annotation on parallel Czech-English texts of the Prague Czech-English Dependency Treebank (PCEDT). The paper describes innovations made to PCEDT 2.0 concerning coreference, as well as coreference information already present there. We characterize the coreference annotation scheme, give the statistics and compare our annotation with the coreference annotation in Ontonotes and Prague Dependency Treebank for Czech. We also present the experiments made using this corpus to improve the alignment of coreferential expressions, which helps us to collect better statistics of correspondences between types of coreferential relations in Czech and English. The corpus released as PCEDT 2.0 Coref is publicly available.

Genres in the Prague Discourse Treebank
Lucie Poláková | Pavlína Jínová | Jiří Mírovský
Proceedings of the Ninth International Conference on Language Resources and Evaluation (LREC'14)

We present the project of classification of Prague Discourse Treebank documents (Czech journalistic texts) for their genres. Our main interest lies in opening the possibility to observe how text coherence is realized in different types (in the genre sense) of language data and, in the future, in exploring the ways of using genres as a feature for multi-sentence-level language technologies. In the paper, we first describe the motivation and the concept of the genre annotation, and briefly introduce the Prague Discourse Treebank. Then, we elaborate on the process of manual annotation of genres in the treebank, from the annotators’ manual work to post-annotation checks and to the inter-annotator agreement measurements. The annotated genres are subsequently analyzed together with discourse relations (already annotated in the treebank) ― we present distributions of the annotated genres and results of studying distinctions of distributions of discourse relations across the individual genres.

Valency and Word Order in Czech — A Corpus Probe
Kateřina Rysová | Jiří Mírovský
Proceedings of the Ninth International Conference on Language Resources and Evaluation (LREC'14)

We present a part of broader research on word order aiming at finding factors influencing word order in Czech (i.e. in an inflectional language) and their intensity. The main aim of the paper is to test a hypothesis that obligatory adverbials (in terms of the valency) follow the non-obligatory (i.e. optional) ones in the surface word order. The determined hypothesis was tested by creating a list of features for the decision trees algorithm and by searching in data of the Prague Dependency Treebank using the search tool PML Tree Query. Apart from the valency, our experiment also evaluates importance of several other features, such as argument length and deep syntactic function. Neither of the used methods has proved the given hypothesis but according to the results, there are several other features that influence word order of contextually non-bound free modifiers of a verb in Czech, namely position of the sentence in the text, form and length of the verb modifiers (the whole subtrees), and the semantic dependency relation (functor) of the modifiers.

Interplay of Coreference and Discourse Relations: Discourse Connectives with a Referential Component
Lucie Poláková | Pavlína Jínová | Jiří Mírovský
Proceedings of the Eighth International Conference on Language Resources and Evaluation (LREC'12)

This contribution explores the subgroup of text structuring expressions with the form preposition + demonstrative pronoun, thus it is devoted to an aspect of the interaction of coreference relations and relations signaled by discourse connectives (DCs) in a text. The demonstrative pronoun typically signals a referential link to an antecedent, whereas the whole expression can, but does not have to, carry a discourse meaning in sense of discourse connectives. We describe the properties of these phrases/expressions with regard to their antecedents, their position among the text-structuring language means and their features typical for the “connective function” of them compared to their “non-connective function”. The analysis is carried out on Czech data from the approx. 50,000 sentences of the Prague Dependency Treebank 2.0, directly on the syntactic trees. We explore the characteristics of these phrases/expressions discovered during two projects: the manual annotation of 1, coreference relations (Nedoluzhko et al. 2011) and 2, discourse connectives, their scopes and meanings (Mladová et al. 2008).

Annotation Tool for Extended Textual Coreference and Bridging Anaphora
Jiří Mírovský | Petr Pajas | Anna Nedoluzhko
Proceedings of the Seventh International Conference on Language Resources and Evaluation (LREC'10)

We present an annotation tool for the extended textual coreference and the bridging anaphora in the Prague Dependency Treebank 2.0 (PDT 2.0). After we very briefly describe the annotation scheme, we focus on details of the annotation process from the technical point of view. We present the way of helping the annotators by several useful features implemented in the annotation tool, such as a possibility to combine surface and deep syntactic representation of sentences during the annotation, an automatic maintaining of the coreferential chain, underlining candidates for antecedents, etc. For studying differences among parallel annotations, the tool offers a simultaneous depicting of several annotations of the same data. The annotation tool can be used for other corpora too, as long as they have been transformed to the PML format. We present modifications of the tool for working with the coreference relations on other layers of language description, namely on the analytical layer and the morphological layer of PDT.

Typical Cases of Annotators’ Disagreement in Discourse Annotations in Prague Dependency Treebank
Šárka Zikánová | Lucie Mladová | Jiří Mírovský | Pavlína Jínová
Proceedings of the Seventh International Conference on Language Resources and Evaluation (LREC'10)

In this paper, we present the first results of the parallel Czech discourse annotation in the Prague Dependency Treebank 2.0. Having established an annotation scenario for capturing semantic relations crossing the sentence boundary in a discourse, and having annotated the first sections of the treebank according to these guidelines, we report now on the results of the first evaluation of these manual annotations. We give an overview of the process of the annotation itself, which we believe is to a large degree language-independent and therefore accessible to any discourse researcher. Next, we describe the inter-annotator agreement measurement, and, most importantly, we classify and analyze the most common types of annotators’ disagreement and propose solutions for the next phase of the annotation. The annotation is carried out on dependency trees (on the tectogrammatical layer), this approach is quite novel and it brings us some advantages when interpreting the syntactic structure of the discourse units.

Proceedings of the Sixth International Conference on Language Resources and Evaluation (LREC'08)

On many examples we present a query language of Netgraph - a fully graphical tool for searching in the Prague Dependency Treebank 2.0. To demonstrate that the query language fits the treebank well, we study an annotation manual for the most complex layer of the treebank - the tectogrammatical layer - and show that linguistic phenomena annotated on the layer can be searched for using the query language.
