Metadata registries comprising sets of categories to be used in data collections exist in many fields. The purpose of a metadata registry is to facilitate data exchange and interoperability within a domain, and registries often contain definitions and examples. In this paper we will argue that in order to ensure completeness, consistency, user-friendliness and extensibility, metadata registries...

A key research focus for conversational case-based reasoning (CCBR) is incremental query elaboration, which is the process of maximizing the extraction of relevant problem state information throughout the querying process. Several companies and researchers have addressed this problem (e.g., by dynamically applying domain-specific plans (Carrick et al., 1999)). Recently, Gupta (2001) demonstrate...

BACKGROUND To examine if the recommended taxonomies for the stages of youth smoking onset are aligned with the beliefs of smoking youth. METHODS The SHAPES Tobacco Module was administered to 23,047 students (grades 9 to 13) in a convenience sample of 29 secondary schools during the 2000-2001 school year in the province of Ontario, Canada. Cross-tabs were used to compare a student's self-perce...

As web taxonomy integration is an emerging issue on the Internet, many research topics, such as personalization, web searches, and electronic markets, would benefit from further development of taxonomy integration techniques. The integration task is to transfer documents from a source web taxonomy to a target web taxonomy. In most current techniques, integration performance is enhanced by refer...

FRamework Assessing Notorious Contributing Influences for Error (FRANCIE) is a framework and methodology for the systematic analysis, characterization, and prediction of human error. It was developed in a NASA Advanced Concepts Project by Idaho National Engineering and Environmental Laboratory, NASA Ames Research Center, Boeing, and America West Airlines, with input from United Airlines and Ida...

The present study investigated the association between traits of the Five Factor Model of Personality (Neuroticism, Extraversion, Openness for Experiences, Agreeableness, and Conscientiousness) and neural correlates of error monitoring obtained from a combined Eriksen-Flanker-Go/NoGo task during event-related functional magnetic resonance imaging in 27 healthy subjects. Individual expressions o...

A taxonomy is a semantic hierarchy, consisting of concepts linked by is-a relations. While a large number of taxonomies have been constructed from human-compiled resources (e.g., Wikipedia), learning taxonomies from text corpora has received a growing interest and is essential for longtailed and domain-specific knowledge acquisition. In this paper, we overview recent advances on taxonomy constr...

This paper describes experiments in Japanese question classification, comparing methods based on pattern matching and machine learning. Classification is attempted over named entity taxonomies of various sizes and shapes. Results show that the machine learning based method achieves much better accuracy than pattern matching, even with a relatively small amount of training data. Larger taxonomie...
