Abstract: The huge amount of unstructured data available on the Web and the intranets creates today an information overloading problem. So, managing the knowledge contained in the textual documents is an important problem of Knowledge Management. Knowledge Extraction from collections of data is possible by Knowledge Discovery in Database (KDD), an interactive and iterative process focused on the exploration of data to discover new and interesting patterns within them. The fundamental phase of KDD process is Data Mining if data are in structured form and Text Mining when they are unstructured. This paper describes a prototype of a vertical corporate portal that implements a KDD process for knowledge extraction from unstructured data contained in textual documents. Text mining is realized through a clustering method that produces a partition of a set of documents on the basis of their contents characterized through the frequency of the words.
