A Text Mining Model by Using Weighting Technology

چکیده
In Latent Semantic Indexing (LSI) has been proven to be a valuable analysis tool with a wide range of applications. However choosing an appropriate number of dimensions for LSI is still a crucial challenge. This paper provides a document vector model, by using weighting technology, to deal with this problem. Our experimental results have demonstrated that this model can detect a dataset structure, help determine an appropriate number of dimensions for LSI.

With the fast increase of the documents, using Text Document Classification (TDC) methods has become a crucial matter. This paper presented a hybrid model of Invasive Weed Optimization (IWO) and Naive Bayes (NB) classifier (IWO-NB) for Feature Selection (FS) in order to reduce the big size of features space in TDC. TDC includes different actions such as text processing, feature extraction, form...
