Creating a Verb Synonym Lexicon Based on a Parallel Corpus (L18-1)
Copied to clipboard
| Challenge: | a new lexical resource called CzEngClass is being built to help define synonyms in a bilingual context. |
| Approach: | They propose to group verb senses into bilingual verbal synonym groups and use a parallel dependency corpus to explore semantic 'equivalence' they argue that existence of core argument mappings and adjunct mappings to a common set of semantic roles is a suitable criterion for a reasonable verb synonymy definition . |
| Outcome: | The proposed resource will be available by mid-2018 . |
Tools for Building an Interlinked Synonym Lexicon Network (L18-1)
Copied to clipboard
| Challenge: | a new lexicon is being developed for cross-lingual (Czech and English) synonyms based on their syntactic and semantic behavior in (bilingual) context. |
| Approach: | They propose to build a new interlinked verbal synonym lexicon called CzEngClass using a tool that helps to keep cross-lingual synonym classes consistent. |
| Outcome: | The proposed lexicon captures cross-lingual (Czech and English) synonyms . the tool, called Synonym Class Editor -SynEd, is customized to build and edit entries . |
Synonymy in Bilingual Context: The CzEngClass Lexicon (C18-1)
Copied to clipboard
| Challenge: | Existing lexical resources for semantic annotation of synonyms are lacking in computational language processing. |
| Approach: | They describe a bilingual lexical resource being built to investigate verbal synonymy in bilingual context and relate semantic roles common to one synonym class to verb arguments. |
| Outcome: | The proposed resource is based on English and Czech WordNet, FrameNet, PropBank, VerbNet (SemLink), and valency lexicons for Czech and English (PDT-Vallex, Vallex, and EngValleX). |
Discourse Coherence Through the Lens of an Annotated Text Corpus: A Case Study (L18-1)
Copied to clipboard
| Challenge: | a corpus-based study of local coherence as established by anaphoric links in discourses is presented . the study uses Czech data present in the Prague Dependency Treebank 3.0 . |
| Approach: | They propose to look at local coherence as established by anaphoric links between elements in the thematic and rhematic parts of sentences. |
| Outcome: | The proposed method takes into account syntactic relations, contextual boundness and coreference and bridging relations. |
