Modeling and Language Support for the Management of Pattern-Bases

Information overloading is today a serious concern that may hinder the potential of modern web-based information systems. A promising approach to deal with this problem is represented by knowledge extraction methods able to produce artifacts (also called patterns) that concisely represent data. Patterns are usually quite heterogeneous and voluminous. So far, little emphasis has been posed on developing an overall integrated environment for uniformly representing and querying different types of patterns. In this paper, the authors consider the larger problem of modelling, storing, and querying patterns, in a database-like setting and use a Pattern-Base Management System (PBMS) for this purpose.
