An integrated environment for management and exploitation of linguistic resources

In this paper we describe two tools that form an integrated environment which can be successfully used for management and exploitation of linguistic resources. Both the tools and the resources were developed within the University of Belgrade Human Language Technology Group. The tools we describe are WS4LR, a software tool that has been developed and used for solving different tasks within the Group, and a Web application named WS4QE, accompanied by several Web services, that enables the solution of various tasks via the Web. Besides a short description of the linguistic resources for Serbian involved, we also describe how the functions of the WS4LR tool can be used for their maintenance and development, as well as some possibilities for Web query expansion offered by the WS4QE Web application and the use of these expanded queries. Application of expanded queries is presented in web search, exploitation of aligned text and spatial data retrieval.
