We build the knowledge representation machinery for answering complex questions in poorly formalized and logically complex domains. Answers are annotated with deductively linked logical expressions (semantic skeletons), which are to be matched with formal representations for questions. Technique of semantic skeletons is a further development of our semantic headerbased approach to question answ...

The Semantic Web is not a single technology, but rather a collection of technologies designed to work together. As a result, research on the Semantic Web intends both to advance individual technologies as well as to integrate them and take advantage of the result. In this paper we present new work on many layers of the Semantic Web, including content generation, web services, e-connections, and...

Some theoretical perspectives propose a semantic system in which categories are represented in different brain regions. Others assume that distinctions are based rather on differences in the demands placed by different categories on shared processing systems. In this study semantic categorization processes were investigated using the recognition potential (RP), an event-related brain response t...

This paper describes a workbench system for constructing a dictionary to interpret compound nouns, which integrates the acquisition of semantic information and interpretation of compound nouns. First, we extract semantic information from a machine readable dictionary and corpora using regular expressions. Then, the semantic relation of compound nouns are interpreted based on semantic relations,...

On the Web 2.0, there are numerous projects for collaboratively creating and using scientific knowledge in a wiki—think of the scientific sections of Wikipedia or domain-specific platforms like PlanetMath. They do, however, not yet offer semantic services that could promote collaboration both of scientific knowledge engineers and of scholars or that take semantics emerged from such communities ...
