A system capable of answering the questions presented in a natural language is discussed. The system is provided with a sophisticated algorithm by which natural language understanding, database processing and procedure generation-execution to the problems specified by the natural language are well combined. As the major problems occurring in the system, a(More)
Practical machine learning algorithms are known to degrade in performance (prediction accuracy) when faced with many features (sometimes attribute is used instead of feature) that are not necessary for rule discovery. To cope with this problem, many methods for selecting a subset of features have been proposed. Among such methods, the filter approach that(More)

This paper is about a new research field called Web Intelligence (WI for short). We try to explain the needs for coining the term as a sub-discipline of computer science for systematic studies on advanced Web related theories and technologies, as well as the design and implementation of Intelligent Web Information Systems (IWIS).
