Abstract

Textual attributes in relational databases contain useful information that sometimes is not handled in a proper way. Syntactic querying of textual fields provides only superficial information, avoiding issues related to the semantics of data. In order to extract relevant information from these fields, a text mining process is conducted. The AP-Sets mining structure allows the building of an intermediate representation for texts based on the Apriori property. This intermediate form has the shape of a lattice of text itemsets, and can be translated into a basic ontology using semantic relations extracted from WordNet lexical database. The ontology generated can be seen as a summarized structured description of the contents of the textual attribute. Furthermore, it adds semantic capabilities to the query process on textual attributes.
