- Abstract
- This article examines searcher behavior and affective response to a hypertext-based bibliographic information retrieval system called HyperLynx for searchers with different search skills and backgrounds. Search times and number of nodes visited were recorded for five specified search queries, and views of the system were recorded for each searcher. No significant differences were found in search times or user satisfaction with the system, indicating that a hypertext-based approach to bibliographic retrieval could be appropriate for a variety of searcher experience levels

- Abstract
- Describes SIFT (Search in Free Text) an information retrieval system originally developed for administering governmental documents in Norway but which is now being applied alsewhere. SIFT handles structured information well. A library system, SIFT-BIBL, is now available. SIFT's retrieval engine and search facilities are powerful. Its user interface is limited but being imporved. An application programmer interface has been released which will allow programmers to develop their own interface. A Windows-based- client-server version is now being beta tested

- Abstract
- People who work in a research, academic or business environemtn often have personal information collections which are large enough to need retrieval aids. A major difference between personal information retrieval and standard information retrieval is that the items to be retrieved are often associated with events in the searcher's life and ca be retrieved by their relationship of other events as well as by content. Describes the background to evenet based retrieval and describes a prototype graphical event based retrieval system, developed at Kent University, UK, employing the hive event browser

- Abstract
- Reports results of the MARS project, conducted at Illinois University, to bring together researchers in the fields of computer vision, compression, information management and database systems with the goal of developing an effective multimedia database management system. Describes the first step, involving the design and implementation of an image retrieval system incorporating novel approaches to image segmentation, representation, browsing and information retrieval supported by the developed system. Points to future directions for the MARS project

- Abstract
- Proceedings of the 5th TREC-confrerence held in Gaithersburgh, Maryland, Nov 20-22, 1996. Aim of the conference was discussion on retrieval techniques for large test collections. Different research groups used different techniques, such as automated thesauri, term weighting, natural language techniques, relevance feedback and advanced pattern matching, for information retrieval from the same large database. This procedure makes it possible to compare the results. The proceedings include papers, tables of the system results, and brief system descriptions including timing and storage information

- Abstract
- This article investigates the potentialities of using empirical variables and their associated statistical relationships in document representation and retrieval. To this end, a newly devised empirical fact retrieval system (EFRS) was evaluated in comparison to a simulated traditional retrieval system (TRS) involving a set of predetermined empirical queries. Results indicate that the EFRS generally outperformed the TRS in terms of precision, search effort, and measures of user satisfaction. Possible advantages of the EFRS, as well as the necessity of establishing an efficient methos for extracting empirical facts, are discussed

- Abstract
- Discusses the complex nature of urban, regional and local documents management, the decision making process of an in house classification system, and problems of converting a manual card cataloguing system to an computerized information retrieval system at Florida International University Library. The principles of this in house classification system can be used for any specialized collection

- Abstract
- Reports on the design of a GUI for the Okapi 'best match' retrieval system developed at the Centre for Interactive Systems Research, City University, UK, for online library catalogues. The X-Windows interface includes an interactive query expansion (IQE) facilty which involves the user in the selection of query terms to reformulate a search. Presents the design rationale, based on a game board metaphor, and describes the features of each of the stages of the search interaction. Reports on the early operational field trial and discusses relevant evaluation issues and objectives

- Abstract
- Describes the design and implementation of a system for computer generation of linked HTML documents to support information retrieval and hypertext applications on the WWW. The system does not require text query input, nor any client or host processing other than hypertext linkage. The goal is to construct a fully automatic system in which original text documents are read and processed by a computer program that generates HTML files, which can be used immediately by Web browsers to search and retrieve the original documents. A user with a large collection of information: for instance, newspaper articles; can feed these documents to this program and produce directly the necessary files to establish WWW home page and related pages, to support interactive retrieval and distribution of the original documents

- Abstract
- Describes 2 research projects aimed at studying the parallel issues of image and video indexing, information retrieval and manipulation: VisualSEEK, a content based image query system and a Java based WWW application supporting localised colour and spatial similarity retrieval; and CVEPS (Compressed Video Editing and Parsing System) which supports video manipulation with indexing support of individual frames from VisualSEEK and a hierarchical new video browsing and indexing system. In both media forms, these systems address the problem of heterogeneous unconstrained collections

- Abstract
- This article is about the mental coding processes involved in the flow of 'information' when the user is interacting with an 'enabling' information retrieval system. An 'enabling' IR system is designed to stimulate the user's grasping towards a higher understanding of the information need / problem / task that brought the user to the IR system. C. Shannon's (1949/1959) model of the flow of information and K.R. Popper's (1975) 3 worlds concept are used to diagram the flow of information between the user and system when the user receives a stimulating massage, with particluar emphasis on the decoding and encoding operations involved as the user processes the message. The key difference between the model of information flow proposed here and the linear transmission, receiver-oriented model now in use is that we assume that users of a truly interactive, 'enabling' IR system are primarily message senders, not passive receivers of the message, because they must create a new message back to the system, absed on a reconceptualization of their information need, while they are 'online' interacting with the system

- Abstract
- The performance of an information retrieval or text and media filtering system may be determined through analytic methods as well as by traditional simulation or experimental methods. These analytic methods can provide precise statements about expected performance. They can thus determine which of 2 similarly performing systems is superior. For both a single query terms and for a multiple query term retrieval model, a model for comparing the performance of different probabilistic retrieval methods is developed. This method may be used in computing the average search length for a query, given only knowledge of database parameter values. Describes predictive models for inverse document frequency, binary independence, and relevance feedback based retrieval and filtering. Simulation illustrate how the single term model performs and sample performance predictions are given for single term and multiple term problems

- Abstract
- Reports on the results of a transaction analysis and user survey, evaluating a pilot system for computerized community information in a public library, based on the GDIS system (Gemeenschaps Informatie Documentair System). The non hierarchical and global approach to the integrated database proved to be useful for novice users. Out of many parameters only frequency of use correlates with retrieval success. The online questionnaire proved to be worthwhile although restricted in scope. The logbook transaction analysis yielded a rich amount of useful management information for the systems managers. The user survey yielded a rich set of data on which to perform statistical analyses according to social science practice, from which some interesting relations could be detected
