We present the results and the lessons learned from two separate and independent studies into the design, development, and evaluation of electronic books for information access: the Visual Book and the Hyper-TextBook. The Visual Book explored the importance of the visual component of the book metaphor in the production of “good” electronic books for referencing. The Hyper-TextBook...

In recent years, small screen devices have seen widespread increase in their acceptance and use. Combining mobility with increased technological advances many such devices can now be considered mobile information terminals. However, user interactions with small display devices remain a challenge due to the inherent input restrictions and limited display capabilities. These challenges are...

This paper describes a number of experiments that explored the issues surrounding the retrieval of spoken documents. Two such issues were examined. First, attempting to find the best use of speech recogniser output to produce the highest retrieval effectiveness. Second, investigating the potential problems of retrieving from a so-called "mixed collection", i.e. one that contains documents from...

We briefly outline the ongoing research at Strathclyde University on the use of spoken query processing for information access in digital libraries.

Although retrieval systems based on probabilistic models will rank the objects (e.g. documents) being retrieved according to the probability of some matching criterion (e.g. relevance) they rarely yield an actual probability and the scoring function is interpreted to be purely ordinal within a given retrieval task. In this paper it is shown that some scoring functions possess the likelihood...

Context has long been considered very useful to help the user assess the actual relevance of a document. In Web searching, context can help assess the relevance of a Web page by showing how the page is related to other pages in the same Web site, for example. Such information is very difficult to convey and visualise in a user friendly way. In this paper we present the design, implementation and...

We propose an approach to content-based Distributed Information Retrieval based on the periodic and incremental centralisation of full content indices of widely dispersed and autonomously managed document sources. Inspired by the success of the Open Archive Initiative’s protocol for metadata harvesting, the approach occupies middle ground between content crawling and distributed retrieval. As...

This paper reports on an experimental study on the differences between spoken and written queries. A set of written and spontaneous spoken queries are generated by users from written topics. These two sets of queries are compared in qualitative terms and in terms of their retrieval effectiveness. Written and spoken queries are compared in terms of length, duration, and part of speech. In...

As part of a Distributed Information Retrieval system a description of each remote information resource, archive or repository is usually stored centrally in order to facilitate resource selection. The acquisition of precise resource descriptions is therefore an important phase in Distributed Information Retrieval, as the quality of such representations will impact on selection accuracy, and...
