EcoLexicon : New Features and Challenges

EcoLexicon is a terminological knowledge base (TKB) on the environment with terms in six languages: English, French, German, Modern Greek, Russian, and Spanish. It is the practical application of Frame-based Terminology, which uses a modified version of Fillmore’s frames coupled with premises from Cognitive Linguistics to configure specialized domains on the basis of definitional templates and create situated representations for specialized knowledge concepts. The specification of the conceptual structure of (sub)events and the description of the lexical units are the result of a top-down and bottom-up approach that extracts information from a wide range of resources. This includes the use of corpora, the factorization of definitions from specialized resources and the extraction of conceptual relations with knowledge patterns. Similarly to a specialized visual thesaurus, EcoLexicon provides entries in the form of semantic networks that specify relations between environmental concepts. All entries are linked to a corresponding (sub)event and conceptual category. In other words, the structure of the conceptual, graphical, and linguistic information relative to entries is based on an underlying conceptual frame. Graphical information includes photos, images, and videos, whereas linguistic information not only specifies the grammatical category of each term, but also phraseological, and contextual information. The TKB also provides access to the specialized corpus created for its development and a search engine to query it. One of the challenges for EcoLexicon in the near future is its inclusion in the Linguistic Linked Open Data Cloud.
