Abstract. Data mining methods have been applied to a wide variety
of domains. Surprisingly enough, only a few examples of data mining in
text are available. However, considering the amount of existing document
collections, text mining would be most useful. Traditionally, texts have
been analysed using various information retrieval related methods and
natural language processing. In this paper, we present our first experi­
ments in applying general methods of data mining to discovering phrases
and co­occurring terms. We also describe the text mining process de­
veloped. Our results show that data mining methods --- with appropriate
preprocessing --- can be used in text processing, and that by shifting the
focus the process can be used to obtain results for various purposes.
1 Introduction
During recent years, data mining, or knowledge discovery, has become a popular
research area. Data mining methods have been applied on a wide variety of
domains, from supermarket basket data and telecommunication alarm data to
the analysis of satellite pictures and human genomes. Aside the growing interest
