Representing Environmental Knowledge in EcoLexicon
EcoLexicon is a multilingual terminological knowledge base (TKB) on the environment, which provides an internally coherent information system covering a wide range of specialized linguistic and conceptual needs. Our research has mainly focused on conceptual modeling with a view to offering a user-friendly multimodal interface. The dynamic interface of EcoLexicon combines conceptual, linguistic, and graphical information and is primarily hosted in a relational database that has been recently linked to an ontology. One of the main challenges that we have faced in the development of our TKB is the information overload generated by the specialized domain. This is not only due to the wide scope and applicability of environmental concepts, but especially to the fact that multiple dimensions of their meaning definition or conceptual description are not always compatible but rather context-dependent. As a result, concepts with an information overload have been reconceptualized according to two contextual factors: domain membership and semantic role. This reduces the amount of conceptual information accessed by the user, and makes the knowledge representation easier to process.
