vector space model Vector space model or term vector model is an algebraic model for representing text documents (and any objects, in general) as vectors of identifiers (such as index terms). It is used in information filtering, information retrieval, indexing and ...

collection: archives of the generalist review ''Time'' in 1963 To the legacy of the SMART system belongs the so-called SMART triple notation, a mnemonic scheme for denoting tf-idf weighting variants in the vector space model. The mnemonic for representing a combination of weights takes the form ddd.qqq, where the first three letters represents the term weighting of the collection document vector and the second three letters represents the term weighting for the query document vector. For example, ltc.lnn represents the ltc weighting applied to a collection document and the lnn weighting applied to a query document. The following tables establish the SMART notation: The gray letters in the first, fifth, and ninth columns are the scheme used by Salton and Buckley in their 1988 paper.Salton, G., & Buckley, C.
