- Abstract
- Describes the OKAPI projects and OKAPI's development as an experimental online catalogue system over 10 years, first at the University of Westminster (formerly the Polytechnique of Central London) and subsequently at City University, London. The 1st OKAPI project in 1984 introduced 'best match' retrieval and focused on the user interface design. The 2nd investigated word stemming, spelling correction and cross reference tables as retrieval aids. A comparative study of 2 library catalogues was undertaken in 1987, while in 1988 query expansion and relevance feedback were introduced and evaluated by laboratory tests. In 1990 live evaluation of automatic query expansion was carried out and in 1993 subject enhancement of bibliographic records was investigated. The latest project has examined the design of a graphical user interface to support interactive query expansion. Discusses the research and evaluation of each project

- Abstract
- Clustering is an effective way of organizing documents into collections for ease of browsing. Recently with the growth of WWW, clustering has become a paradigm for organizing search results. Online systems face many new challenges, including the need for fast response time, generating high quality clusters with simple descriptions for novice users, and working with document distributions that violates many traditional assumptions. How do different clustering algorithms trade off quality of clusters and speed? What modifications are necessary to adapt traditional clustering algorithm to the WWW? How do these system scale to larger document collection? How do these systems evaluate the quality of the cluster they generate? How are the clusters generated in each case, and are there any processing after cluster generation to improve on the cluster quality?

- Abstract
- This article presents a novel user-oriented interface for generalised informetric analysis and demonstrates how informetric calculations can easily and declaratively be specified through advanced data modelling techniques. The interface is declarative and at a high level. Therefore it is easy to use, flexible and extensible. It enables end users to perform basic informetric ad hoc calculations easily and often with much less effort than in contemporary online retrieval systems. It also provides several fruitful generalisations of typical informetric measurements like impact factors. These are based on substituting traditional foci of analysis, for instance journals, by other object types, such as authors, organisations or countries. In the interface, bibliographic data are modelled as complex objects (non-first normal form relations) and terminological and citation networks involving transitive relationships are modelled as binary relations for deductive processing. The interface is flexible, because it makes it easy to switch focus between various object types for informetric calculations, e.g. from authors to institutions. Moreover, it is demonstrated that all informetric data can easily be broken down by criteria that foster advanced analysis, e.g. by years or content-bearing attributes. Such modelling allows flexible data aggregation along many dimensions. These salient features emerge from the query interface's general data restructuring and aggregation capabilities combined with transitive processing capabilities. The features are illustrated by means of sample queries and results in the article.

- Abstract
- This paper reports on usability evaluation that was carried out to evaluate the LRM-based prototype interface, presented in Part 1. A combination of focus group, Wizard of Oz method, and think-aloud protocol was used. The study was conducted in May 2019 with seven Slovenian catalogers from Maribor Public Library. Although participants had some difficulties understanding the LRM model, the user interface proved to be quite easy to use, quick to understand, and transparent. The functionality of the proposed prototype proved to be adequate, since the catalogers successfully and independently completed all the tasks without major problems and errors.

- Abstract
- Adaptive interfaces have received much criticism because adaptation and automatic assistance generally contradict the principles of direct-manipulation interfaces. In addition, their success depends highly on the ability of user models to capture the goals and needs of the users. As the construction of user models is often based on poor evidence, even the most advanced learning algorithms may fail to infer accurately the user goals. Previous research has put little emphasis on investigating usability problems of adaptive systems and developing interaction techniques that could resolve these problems. This paper examines these problems and presents an interaction model for adaptive hypermedia (AH) that merges adaptive support and direct manipulation. This approach is built upon a new content adaptation technique that derives from fisheye views. This adaptation technique supports incremental and continuous adjustments of the adaptive views of hypermedia documents and balances between focus and context. By combining this technique with visual representations and controllers of user models, we form a twofold interaction model that enables users to move quickly between adaptation and direct control. Two preliminary user studies exhibit the strengths of our proposed interaction model and adaptation technique. Future extensions to our work are outlined based on the weaknesses and limitations that the studies revealed.
