SynSemClass

Event-type Ontology in Multiple Languages

(Czech, English, German, Spanish)

 

Introduction

 

The project attempts to create specifications and definitions of a hierarchical event-type ontology, populated with words denoting events or states (primarily verbs, verbal nouns, and adjectives, but also any other single- or multiword units denoting events or states). It links its entries or "classes" (and the words that evoke them) to several existing lexical resources that exist and has, to some extent, similar goals; such linking allows for both theoretical and practical comparison and use of the resources.

 

Quick links to the current version of SynSemClass: the browser, the search tool, download (ZIP/XML), source code (GitHub).

 

 

The project has dynamically evolved from the original idea to create a bilingual synonym lexicon, which has focused on contextually-based synonymy and valency of verbs in a bilingual setting. The analysis of semantic ‘equivalence’ (synonymy or near synonymy) of verb senses, and their valency behavior in parallel Czech-English language resources (linked to the Prague Dependency Treebank family, and in turn, to the underlying Functional Generative Description theory) was in its core. It has used translational context, which helped to define the properties of verb sense classes of synonyms. An initial sample bilingual verb lexicon of classes representing synonym or near-synonym pairs of verbs (verb senses) based on richly annotated corpora and existing lexical resources have been created. Based on the contribution of that original project, a follow-up project has been set up to add more languages, gearing towards an ontology view of event types.

 

In fact, there has been a predecessor project before the original bilingual approach, which was of great use (both as a resource and as an inspiration), namely the project called A comparison of Czech and English verbal valency based on corpus material (theory and practice). In all projects, the richly annotated Prague Czech-English Dependency Treebank (PCEDT) served as the source of corpus material and examples, which are also included in the resulting resources.

 

For other languages, standard parallel corpora have to be used with automatic alignment techniques to preselect words that are possibly evoking the existing classes, and then the usual manual annotation (i.e., entry expansion) process begins, supported by various analytical and annotation tools.

 

The resulting resource will be always freely available for academic purposes through the LINDAT/CLARIAH-CZ Research Infrastructure repository and online services, including a web/based browsing and search tool. The central repository of the source code developed under the SynSemClass project can be found at GitHub.
It is also linked back to the Unified Verb Index available at the University of Colorado Boulder.

 The project uses (and links back to) the following lexical resources: 

The latest version online (SynSemClass 5.0, English-Czech-German-Spanish)

The current (latest) version of SynSemClass is SynsemClass5.0 (see also below in more detail; download and browse here: SynsemClass5.0. For searching data you can use the SynSemClass Search Tool.

This version contains also data from previous versions, see below (SynSemClass1.0 - SynSemClass4.0) for all the contributors.

PhDr. Zdeňka Urešová, Ph.D. is in charge of the SynSemClass project.

Mgr. Eva Fučíková provides technical support.

prof. RNDr. Jan Hajič, Dr. is the PI of LINDAT/CLARIAH-CZ and of the LuSyD project and coordinates the expansion work on the lexicon.

Prof. Georg Rehm, Ph.D., (2021) of DFKI Berlin, is the Co-PI of the Humane AI Net microproject META/O/NLU which adds the German language.

Karolina Zaczynska, M.A,  (2021) of DFKI Berlin/Univ. of Potsdam, is leading and coordinating the linguistic specification and annotation effort for German.

SynSemClass 3.5: Czech-English-German

The SynsemClass3.5 (download: SynSemClass3.5, search and browse: SynSemClass version 3.5 web) which adds new German verb synonyms. Based on both parallel Czech-English and German-English language resources, it now collects and investigates semantic ‘equivalence’ of Czech, English, and German verb senses and their valency behavior in parallel Czech-English and German-English corpora In addition to the already used external links (see above) to Czech and English semantic lexicon entries, new German-language lexical resources are exploited: FrameNet des Deutschen, Woxikon, Elektronisches Valenzwöerterbuch Deutscher Verben, and German Universal Proposition Bank. Some more Czech and English verbs are also included (compared to version 3.0).

The German part of the lexicon has been created within the project Multilingual Event-Type-Anchored Ontology for Natural Language Understanding (META-O-NLU), a microproject that lasted from January to June 2021, as part of the Humane AI Net EC-funded Center of Excellence in AI (project No. 952026), by two cooperating teams:

  1. The team of the Charles University, Faculty of Mathematics and Physics, Institute of Formal and Applied Linguistics, Prague (ÚFAL), Czech Republic - PhDr. Zdeňka Urešová, Ph.D., Mgr. Eva Fučíková, PhDr. Kateřina Rysová, Ph.D., prof. RNDr. Jan Hajič, Dr., and prof. PhDr. Eva Hajičová, DrSc.
  2. The team of the German Research Center for Artificial Intelligence (DFKI) Speech and Language Technology, Berlin, Germany - prof. Dr. Phil. Georg Rehm, Karolina Zaczynska, and Peter Bourgonje (currently from the University of Potsdam).
