Information granulation for web-based information support systems
2003
Data Mining and Knowledge Discovery: Theory, Tools, and Technology V
Preserved Fulltext
In particular, we apply clustering methods for the granulation of different entities involved in IRSS. Two types of granulations, single-level and multi-level granulations, are investigated. ...
In this paper, we discuss the potential applications of data mining techniques for the design of Web based information retrieval support systems (IRSS). ...
They allow multi-representation of documents. Granular computing plays an important role in the construction of document models. The retrieval models deals with the search functionality. ...
