9:15-9:30Introduction: Lexical Resources for Knowledge Organization
9:30-10:40Keynote: Christina Unger (CITEC, University of Bielefeld)

Automatic extraction of ontology lexica in multiple languages

Many applications that need to mediate between natural language and Semantic Web data, such as question answering and verbalization of ontologies or RDF datasets, require knowledge about how elements of the vocabulary are expressed in natural language. Moreover, in case a system is supposed to be multilingual, this knowledge is needed in multiple languages. In this talk, I present recent approaches to automatically acquiring such lexical knowledge, and outline some of the main limitations these approaches still face.

“Wissensorganisation” is the name of a series of bi-annual conferences/workshops with a long tradition organized by the German chapter of the International Society of Knowledge Organisation (ISKO).

Knowledge organization as discipline has a long standing tradition. Traditional knowledge organization focusses on the description and structuring of knowledge in libraries, archives, databases, scientific domains, etc. Besides formal relations, more or less all knowledge organization systems (KOS) use words from natural languages and short phrases to describe the concepts in the system. Though knowledge organization systems are not intended to be used as lexical resources, the meaning of the terms in a KOS usually is closely related to their common meaning in science or application fields. Thus to some extent a KOS also can figure as lexical resources.

Lexical resources (LR) provide linguistic information about words. This information can be represented in very diverse data structures, from simple lists to complex resources with many types of linguistic information and relations associated with the entries stored in the resource. Since most KOSs use natural language to describe concepts, LRs can have a high value for the construction and extension of KOSs and for the identification of concepts of KOSs in texts.

The workshop wants to contribute to the discussion and identification of future research that combines language resources, especially lexical resources in the context of knowledge organization.

The topics of interest include, but are not limited, to the following aspects:

  • The Relation between Knowledge Organization Systems and Lexicons
  • The Role of Natural Language Labels for Concepts in Thesauri and Ontologies
  • Indexing of Texts with Concepts from Knowledge Organization Systems
  • Using Text Corpora for the Construction and Extension of Knowledge Organization Systems
  • Classification Schemes, Taxonomies, and Categorization Schemes
  • Thesauri, Semantic Networks and Ontologies
  • Knowledge Modeling and Engineering
  • Engineering and Management Aspects of Knowledge Organization
  • Automatic Categorization and Indexing
  • Knowledge Organization Systems for Understanding, Sensemaking, and Learning
  • Knowledge Organization Systems for Knowledge Discovery in Very Large Datasets
  • Organization of Unstructured Information
  • Knowledge Organization for the Future
