Text mining is a branch of data mining that extracts useful information from various data sources for the purpose of predication, analysis, classification and clustering of text. Here in this context, we will d
In text mining and information retrieval, as well as in other applications such as bioin-formatics, we are interested in an angle between document vectors, hence, it is convenient to consider sets of normalized vectors. A wide variety of clustering algorithms applicable for objects of general ...

In this example, after applying K-NN, the blue data point is classified to be of type C-1 because it has been determined to be closer to majority of the data points in C-1. For discrete variables, such as in natural language processing, Hamming Distance can be used for text ...

6.3 Clustering and data mining applications In general, clustering is the unsupervised classification of patterns into groups. The main concentration of clustering is to split a group of datasets into clusters based on the relationship between the elements within the same cluster. For decades, data ...
To alleviate the problem of high dimensions in text clustering, an alternative to conventional methods is bipartite partitioning, where terms and documents are modeled as vertices on two sides respectively. Term weighting schemes, which assign weights to the edges linking terms and documents, are vita...
