    Abstract
    Shows how probabilistic information retrieval based on document components may be implemented as a feedforward (feedbackward) artificial neural network. The network supports adaptation of connection weights as well as the growing of new edges between queries and terms based on user relevance feedback data for training, and it reflects query modification and expansion in information retrieval. A learning rule is applied that can also be viewed as supporting sequential learning using a harmonic sequence learning rate. Experimental results with 4 standard small collections and a large Wall Street Journal collection show that small query expansion levels of about 30 terms can achieve most of the gains at the low-recall high-precision region, while larger expansion levels continue to provide gains at the high-recall low-precision region of a precision recall curve

    Abstract
    The transition from searching in a single database to searching a multiplicity of networked databases exacerbates some old difficulties in the design and evaluation of retrieval systems and creates new one. A networked environment calls into question the traditional definitions of recall and relevance. Efficient network searching raises questions about where to look first, where to look next and when to stop searching. The need for 'entry vocabulary' support and the need for support in moving from one system vocabulary to another are increased by the increased use of more different databases. The network environment offers the option of collecting different representations of the same object and merging them into an extended record
