TEXT MINING PRODUCTS
The central idea of text mining is natural knowledge processing. Hence the products of text mining system are centred around natural language processing. By natural language processing many products can be obtained. We can classify these products broadly under two categories. These are:
• The first categories of products are centred on document organization, visualization, and navigation. In this category of product unstructured set of documents are navigated and organize to become structured set. In this category usually retrieval of information doesn’t not takes place.
• The second categories of text mining products are centred on information retrieval and knowledge discovery through natural language processing techniques. In this category of products sophisticated search is performed with the help of various available text mining tools to get the desired result. The following processes are involved in natural language processing: [2].
• text analysis
• text categorization
• information extraction
• summarization
