HypIR: Hypertext Based Information Retrieval

Abstract

Information Retrieval (IR), which is also known as text or document retrieval, is the process of locating and retrieving docri)nents that are relevant to the user queries. In hypertext environments, docuinent databases are organized as a network of nodes which are interconnected by various types of links. This study introduces a hypertext-based text retrieval system, HypIR. In HypIR, the sentantic relationships ainong docuinents are obtained using a clustering algorithm. A new approach providing the advantages of system maps and history list is introduced to prevent the user fiotn being lost in the IR hivperspace. The paper presents the underlying concepts and iinplementation details. HypIR is based on the object-oriented paradigm and its execution platforin is HyperCard.
