- Abstract
- Describes a typical traditional 1989 free text system and discusses developments in data storage, in search strategy and in the storage and retrieval of real time data. Outlines the following areas in which free text systems are likely to develop: standards; integration; dynamic data exchange; improved user interfaces; and better retrieval methods

- Abstract
- The many techniques developed for the storage and retrieval of textual information have also become available for the storage and retrieval of graphics and images in various kinds of database systems. Of the many existing software packages for information storage and retrieval, a fast growing number offer the possibility of storing images. As part of a software evaluation project, criteria for the evaluation of image capabiblities of retrieval software packages are listed and these criteria are used to report on the graphical capabilities of the following software packages: Advision, askSam, Cardbox for Windows, FolioViews, IdeaList, Inmagic-Image, KAware, Personal Librarian and ZyImage

- Abstract
- Most of the criteria proposed to date for the evaluation of OPACs focus on evaluation of their retrieval function. Argues that the storage function is more important because the quality of information retrieval systems is dependent on the quality of stored information as well as the description and depth of indexing of stored information. States that OPACs should therefore be evaluated from the perspectives of both storage and retrieval functions. Examines 4 studies on criteria for evaluating OPACs and suggests a new evaluation framework based on the work of C.R. Hildreth

- Abstract
- This volume deals with both theoretical and empirical research in classification and encompasses universal classification systems, special classification systems, thesauri and the place of classification in a broad spectrum of document and information systems. Papers fall into one or three major areas as follows: 1) general principles and policies 2) structure and logic in classification; and empirical investigation; classification in the design of various types of document/information systems. The papers originate from the ISCCR '91 conference and have been selected according to the following criteria: relevance to the conference theme; importance of the topic in the representation and organization of knowledge; quality; and originality in terms of potential contribution to research and new knowledge.

- Abstract
- Shows how an application in office information systems can be modelled so that a dynamically growing database of hypertext documents is created and automatically extended, as well as easily searched. Proposes a method for analyzing office applications which relies on a model based on statecharts to record the flow of documents within the system. A prototype implementation is described of a hypertext system to support the creation, storage and retrieval of documents associated with formal face to face meetings. Special features to be incorporated into hypertext systems aimed at supporting the storage and retrieval of office documents are also identified

- Abstract
- Database management systems (DBMSs) are a major component of most information systems (ISs). The relational DBMS is nowadays by the far most widely accepted DBMS, although many large non-relational DBMSs are still in use, and object oriented DBMSs are developing. Besides, more and more DBMSs are supporting basic multimedia storage and retrieval facilieties. Nevertheless, advanced information retrieval facilities, especially for accessing large document and text databases, are still the almost exclusive domain of information storage and retrieval systems (IRSs). A growing need is identified to integrate the facilities of a DBMS and an IRS in order to fully support work with multiple data types, like multimedia police work. For Dutch police departments, a criminal investigation system is developed, fully integrating both types of facilities

- Abstract
- The performance of an information retrieval system depends on its ability to distinguish between relevant and non relevant documents in response to users' information needs. Proposes a new method called Codon Signatures (CS) that is able to use a relationship between terms and concepts. The Codon Signature is designed to improve retrieval performance (recall and precision) by creating the Codon structure, a representation of semantic meaning in context. It is also designed to reduce the amount of storage space required by the index. Presents a theoretical analysis of CS paprameters and performance. The method was tested against 3 document base collections and gave acceptable results regarding information effectiveness and efficiency, compared to a conventional Signature Files method

- Abstract
- This chapter introduces and defines basic IR concepts, and presents a domain model of IR systems that describes their similarities and differences. The domain model is used to introduce and relate the chapters that follow. The relationship of IR systems to other information systems is discussed, as is the evaluation of IR systems
