Text document representation models – literature review

Three (currently) most popular document representation methods are : Vector Space Model – VSM TF-IDF & Cosine similarity Latent Semantic IndexingThe Vector Space Model, document representation method, doesn’t give the semantic relations of term. The LSIThe Vector Space Model, document representation method, doesn’t give the semantic relations of term. The LSI method overcomes the limitation of VSM. LSI is an approach that use particular matrix transformation technique called Singular Value Decomposition (SVD).... More method overcomes the limitation of VSM.
