It is demonstrated on this basis that three document test collections. Cluster based retrieval experi human knowledge is not an incoherent patchwork of bits and ments using the single l!�kage clusters obtained from these ma pieces but rather a well structured system. The procedure to justify idces show that the cosine and Ta nimoto coefficients generally this claim is based on an analysis of linguistic expressions. 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. Comparable re vide the basis to arrive at a fundamental classification of human sults were obtained in experiments using a modification of the knowledge. Using the two semantic relations similarity and pre Cluster Hypothesis test to measure the extent of the separation of supposition a three dimensional space is found containing about relevant from nonrelevant documents caused by the use of a par 1,300 categories and about 45 larger units (called models). The ticular combination of weighting function and Similarity coeffi first part contains an elaboration of the dimension and some major cient.
