    Abstract
    It is first argued that classification schemes have an essentially hypothetical nature, whose adoption is not anything which can be true or false. Such schemes are therefore corrigible and susceptible of modification as fresh data accrue. These schemes are tools for the logical analysis of the structure of recorded knowledge. Their use amount to the adoption of a hypothesis. ... It is therefore imperative that classification schemes be devised which do allow us to deal with sets of documents that change with time. The formal bases of two such schemes are next described. They are known, respectively, as implicative lattices and subtractive lattices ...

    Abstract
    Two widerly used criteria for evaluating the effectiveness of information retrieval systems are, respectively, the recall and the precision. Since the determiniation of these measures is dependent on a distinction between documents which are relevant to a given query and documents which are not relevant to that query, it has sometimes been claimed that an accurate, generally valid evaluation cannot be based on recall and precision measure. A study was made to determine the effect of variations in relevance assesments do not produce significant variations in average recall and precision. It thus appears that properly computed recall and precision data may represent effectiveness indicators which are gemerally valid for many distinct user classes.
