This special interest group facilitates discussions among the researchers who are interested in "language service ontology."

A "language service" is a Web service whose functionalities are related to natural language. There could be a wide range of language services, from a specialized one, such as linguistic analysis (e.g. morpho-syntactic analysis), to a more general service that could benefit users in accessing dictionaries and/or translating messages into other languages.

The "language service ontology" will serve as a common ground for describing technical elements of a language service in the context of open and distributed language infrastructures. These elements include static language resources, such as lexicons, corpora, algorithmic Natural Language Processing (NLP) resources, as well as abstract linguistic objects, such as linguistic expression, meaning, and annotation.

The ontology-based description of language services ensures interoperability among services, thereby enabling each service to be incorporated into a composite language service. Users might be able to choose any service provided on an infrastructure, such as the Language Grid, to make a composite service tailored to their needs.

The ontology will also serve as guidelines for users creating their own language resources. For example, a number of nonprofit organizations operating in multilingual communities have recently been creating their own language resources. Such resources, however, tend to be used only within a community because of the lack of interoperability. The ontology will help users to create language resources much more easily and to use them more effectively in combination with other resources provided on the Internet.

The goal of developing a comprehensive language service ontology, on which all concerned can agree, calls for thorough discussions among experts from the relevant fields and the establishment of international standards. This special interest group will serve as a vital body for facilitating such discussions among researchers specializing in the related fields, such as NLP, Semantic Web, and AI planning. We will also support relevant research that is based on international research collaborations.

From 2006 through 2007 (in Japanese fiscal year), we have been supported by "R&D promotion scheme funding international joint research" promoted by NICT, Japan. With this research grant, we have jointly worked on this subject with colleagues at DFKI (Germany) and CNR-ILC (Italy).
