Data Mining Algorithm for Text Data

This paper presented two ways of knowledge discovery in database (KDD) for text data, then utilized one way which is based on current data mining for structured data to present a method of KDD for unstructure data——tree structured and multiple layered database (TSMLDB). The method analyzed the text data, made it quasi structured and stored in TSMLDB. Based on the existent database technology and specific operations on TSMLDB, this paper implemented the data extraction and control in the process of knowledge discovery, and presented the detailed model and process.
