Abstract
From the 1994 CAIS Conference: The Information Industry in Transition McGill University, Montreal, Quebec. May 25 - 27, 1994.Bibliographic or full text information retrieval (IR) applications have been implemented either as special purpose programs or as systems based on database technology. The relational model has been used with some success but most work has used separate IR specific models. The object-oriented data model offers many advantages by incorporating documents as complex objects. Basic concepts such as objects, class hierarchy, inheritance, aggregation, collections and methods are applied to the IR situation. Various approaches to query processing are introduced. To illustrate these concepts a partial implementation in object-Pascal is presented. Problems of standardization and formalization are discussed.
