摘要：Data Mining is the process to extract hidden predictive information from database and transform it into understandable structure for future use. The assorteddomains in data mining are Web Mining, Text Mining, Sequence Mining, Graph Mining, Temporal Data Mining, Spatial Data Mining (SDM), Distributed Data Mining (DDM) and Multimedia Mining. Some of the applications of data mining, it is used for financial data analysis, retail and telecommunication industries, science and engineering and intrusion detection and prevention. In this paper we discussed about the text mining techniques and its applications. Text mining is used to extract interesting information or knowledge or pattern from the unstructured texts that are from different sources. It converts the words and phrases in unstructured information into numerical values which may be linked with structured information in database and analyzed with ancient data mining techniques. There are many techniques used in text mining such as information extraction, information retrieval, natural language processing (NLP), query processing,categorization and clustering
