The cus­ give rather better levels of retrieval effectiveness than the vector tomary local approaches based upon numerical feature analyses of product and overlap coefficients. The results also suggest that al­ linguistic expressions are criticized. In contrast to these it is pro­ though inverse frequency weighting may by useful in certain cir­ posed a global procedure based upon an investigation of large cumstances, it does not consistently lead to significant increases in scale lexical material. It is argued that the verbs of a language pro­ performance over the use of unweighted terms.
