Using Concept Formal Analysis for Cooperative Information Retrieval

cessary to abstract it and eliminate the redundancy data. In this context, a method for data reduction based on the formal concept analysis is proposed in [16,17]. At the same time, new IR domains have been investigated including different types of information (email messages, web documents,..). Thus, there is nowadays a much better awareness of the strengths and limitations of this technique for organising and searching distributed information. We are interested by searching in distributed information. So, this paper is organized as follows. In section 2, we introduce some basic definitions on formal analysis. Then in section 3, we present the data reduction. The section 4 is devoted to the presentation of several methods for searching in distributed information. In section 5, we present the complexity of those methods. 0DWKHPDWLFDO )RXQGDWLRQV Among the mathematical theories found recently with important applications in computer science, lattice theory has a specific place for data o...
