Research on Text Representation Model Integrated Semantic Relationship

Word-text matrix has been usually used as text representation model in text classification and text clustering. However its high dimension and sparsity reduce its expression ability. For improving its expression ability, authors mine word word relation and text-text relation, and integrate these semantic relationships into word-text matrix. The classification experiments show that these new representation models can improve the classification accuracy of text efficiently as well as represent the text information better.
