Re: What is LSI seo & LSA ?
One point in the LSI according to a predetermined condition scoring system, building a term document matrix. This is broken down into three new matrices. Then they are truncated to eliminate noise. The right eigenvectors of the so-called SVD is the document vector coordinates and the so-called left eigenvector, vector coordinates.The Coordinate Calculation of term of the query vector tutorial.From described in a document file can be calculated in a similar query and ranked in descending order similar values. The correct feature vector can be used to document, document clustering and the left eigenvectors can be used for long-term cluster. In each case the cosine similarity value as the period is normally calculated using the number of vector models.Such clustering opened the door Infrared spectroscopy, such as automatic thesaurus construction, classification, keywords and file
