We present an ontology-driven approach to semantic annotation, indexing and retrieval of document units. This approach is based on a novel semantic document model (SDM) that we developed to make office-like document units be uniquely identified, semantically annotated with concepts from annotation ontologies and linkable across document boundaries. In the semantic annotation model that we...

The ability to infer the characteristics of offenders from their criminal behaviour (‘offender profiling’) has only been partially successful since it has relied on subjective judgments based on limited data. Words and structured data used in crime descriptions recorded by the police relate to behavioural features. Thus Language Modelling was applied to an existing police archive to link ...

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.

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...
