Multilingual groups often find communication difficult. Even with human interpreters, these groups still suffer from the inherent limitations of oral meetings: only one person at a time can talk, comments are not anonymous, and ideas must be recorded manually. Group Support Systems (GSS) have been used to increase the productivity of traditional, oral meetings by allowing participants to exchange automatically recorded, typed comments simultaneously and anonymously. Integration of language translation software with these systems could enable multilingual groups to achieve the same benefits obtained by monolingual groups. This paper investigates the feasibility of using automatic language translation in GSS meetings …

Naturalness Of Ontology Concepts For Rating Aspects Of The Semantic Web, Yoo Jung An, Kuo-Chuan Huang, James Geller
Communications of the IIMA
The Semantic Web is expected to be the next generation of the WWW. Ontologies and agents are major ingredients of the Semantic Web. In (Lee and Geller 2005), we have argued that some existing ontologies make use of unnatural concepts. We stated that unnatural concepts make it difficult to use an ontology and they contradict the purpose of an ontology, which includes explanatory power for the purpose of sharing information. In this paper we elaborate what makes a concept unnatural. We also analyze existing ontologies to get numeric measures of how natural their concepts are.
