    Abstract
    Provides an introduction to the computational techniques that underlie best match searching retrieval systems. Discusses: problems of traditional Boolean systems; characteristics of best-match searching; automatic indexing; term conflation; matching of documents and queries (dealing with similarity measures, initial weights, relevance weights, and the matching algorithm); and describes operational best-match systems

    Abstract
    Studies of document retrieval systems have suggested that the degree of consistency in the terms assigned to documents by indexers is positively associated with retrieval effectiveness. The study investigated the consistency of assignment of links in separate hypertext versions of the same full text database assuming that a measure of agreement may be related to the subsequent utility of the resulting hypertext document. Describes the calculations involved in measuring the degree of similarity between pairs of structured objetcs of a certain type (Those that may be represented in graph theoretic form). Initial results show little similarity between the sets of links identified by different people and this finding is comparable with those of studies of inter indexer consistency, where it has been found that there is generally only alow level of agreement between the sets of indexing terms assigned to a document of different indexers
