    Abstract
    A method for automatically generating Boolean queries from weighted search terms is described. The method is intended to exploit traditional Boolean information retrieval systems in a more user-friendly way. The principal advantage of the method we present is that its computational complexity is low in comparison to many other known methods

    Abstract
    The traditional recall and precision measure is inappropriate when retrieval algorithms that retrieve information from Wide Area Networks are evaluated. The principle reason is that information available in WANs is dynamic and its size os orders of magnitude greater than the size of the usual test collections. To overcome these problems, a new efffectiveness measure has been developed, which we call the 'usefulness measure'
