AUTOR: Anna Nedoluzhko AFILIACJA: Charles University in Prague 27 kwietnia 2015: TYTUŁ: Annotation of textual phenomena in the Prague Dependency Treebank STRESZCZENIE: The presentation describes the annotation of discourse relations in the Prague Dependency Treebank (PDT). We will first present PDT 3.0 and its multilayer annotation (morphological, syntactic and complex semantic layers). Then, we will concentrate on the discourse annotation layer which includes the annotation of coreference links, bridging relations, information structure and discourse relations. The special attention will be paid to annotation principles and the analysis of inter-annotator disagreements. 28 kwietnia 2015: TYTUŁ: Coreferential expressions in English and Czech STRESZCZENIE: In this talk, we will present a comprehensive study on mappings between certain classes of coreferential expressions in English and Czech. We focus on central pronouns, relative pronouns and anaphoric zeros. For instance, the English sentence 'It switched to a caffeine-free formula using its new Coke in 1985' has been in PCEDT translated to 'V roce 1985 přešla na bezkofeinovou recepturu, kterou používá pro svojí novou kolu'. This pair of sentences exhibits several types of changes in expressing coreference: English personal pronouns turns into a Czech zero, possessive pronoun into a possessive reflexive and finally, the -ing participle has been translated to a relative clause. In a similar manner, we have collected a statistics of mappings from a subsection of PCEDT, which we will support by multiple examples and contrast with the theoretical assumptions. For such a study, the quality of word alignment is crucial. Thus, we designed a rule-based refining algorithm for English personal and possessive pronouns and Czech relative pronouns, which served as an automatic alignment pre-annotation. Subsequently, this annotation has been manually corrected and completed, obtaining a basis for this empirical study. 30 kwietnia 2015: TYTUŁ: Coreference in Czech and cross-lingually – ideas and perspectives STRESZCZENIE: The talk presents manual annotation of coreference relations in more detail: coreference resolution experiments, manual annotation of English (Ontonotes vs. PCEDT, problematic cases (generics, premodifiers, etc.)), (dis)agreements, coreference chains in Czech vs. English vs. Russian.
