- Abstract
- Current approaches to text retrieval based on indexing by words or index terms and on retrieving by specifying a Boolean combination of keywords are well known, as are their limitations. Statistical approaches to retrieval, as exemplified in commercial products like STATUS/IQ and Personal Librarian, are slightly better but still have their own weaknesses. Approaches to the indexing and retrieval of text based on techniques of automatic natural language processing (NLP) may soon start to realise their potential in terms of improving the quality and effectiveness of information retrieval. Examines some of the current attempts at using various NLP techniques in both the indexing and retrieval operations

- Abstract
- A variety of methods for speeding up the response time of information retrieval processes have been put forward, one of which is the idea of thresholding. Thresholding relies on the data in information retrieval storage structures being organised to allow cut-off points to be used during processing. These cut-off points or thresholds are designed and ised to reduce the amount of information processed and to maintain the quality or minimise the degradation of response to a user's query. TREC is an annual series of benchmarking exercises to compare indexing and retrieval techniques. Reports experiments with a portion of the TREC data where features are introduced into the retrieval process to improve response time. These features improve response time while maintaining the same level of retrieval effectiveness

- Abstract
- Reports results of research to develop an information retrieval technique employing a conceptual distance measure between words and based on a large thesaurus. The techniques is specifically designed for data sharing in large scale autonomous distributed federated databases (FDBS). The prototype federated dictionary system, FEDDICT, stores information on the location of data sets within the FDBS and on semantic relationships exisitng between these data sets. WordNet is used and tested as the medium for bulding and operating FEDDICT

- Abstract
- Video is a communications medium that normally brings together moving pictures with a synchronized audio track into a discrete piece or pieces of information. A "piece" of video is variously referred to as a frame, a shot, a scene, a Clip, a program, or an episode; these pieces are distinguished by their length and by their composition. We shall return to the definition of each of these in the section an automatically structuring and indexing digital video. In modern society, Video is commonplace and is usually equated with television, movies, or home Video produced by a Video camera or camcorder. We also accept Video recorded from closed circuit TVs for security and surveillance as part of our daily lives. In short, Video is ubiquitous. Digital Video is, as the name suggests, the creation or capture of Video information in digital format. Most Video produced today, commercial, surveillance, or domestic, is produced in digital form, although the medium of Video predates the development of digital computing by several decades. The essential nature of Video has not changed with the advent of digital computing. It is still moving pictures and synchronized audio. However, the production methods and the end product have gone through significant evolution, in the last decade especially.

- Abstract
- Hypertext uses a browsing rather than a searching strategy. Hypertext systems have found applications in a number of areas. They give users choice of information but this can prove a drawback. Examnines the effectiveness of hypertext as a way of retrieving information and reviews conventional information retrieval techniques. Considers previous attempts at combining information retrieval and hypertext and outlines a prototype systems developed to generate guided tours for users to direct them through hypertext to information they have requested. Discusses how adding this kind of itelligent guidance to a hypertext system would affect its usability as an information system

- Abstract
- Describes an approach to semi-automatically generate a hypertext from linear texts, based on initially creatign nodes and composite nodes composed of 'mini-hypertexts'. Node-node similarity values are computed using standard information retrieval techniques and these similarity measures are then used to selectively create node-node links based on the strength of similarity between them. The process is a novel one because the link creation process also uses values from a dynamically computed metric which measures the topological compactness of the overall hypertext being generated. Describes experiments on generating a hypertext from a collection of 846 software product descriptions comprising 8,5 MBytes of text which yield some guidelines on how the process should be automated. This text to hypertext conversion method is put into the context of an overall hypertext authoring tool currently under development

- Abstract
- This paper reports on an investigation into the scholarly impact of the TRECVid (Text Retrieval and Evaluation Conference, Video Retrieval Evaluation) benchmarking conferences between 2003 and 2009. The contribution of TRECVid to research in video retrieval is assessed by analyzing publication content to show the development of techniques and approaches over time and by analyzing publication impact through publication numbers and citation analysis. Popular conference and journal venues for TRECVid publications are identified in terms of number of citations received. For a selection of participants at different career stages, the relative importance of TRECVid publications in terms of citations vis à vis their other publications is investigated. TRECVid, as an evaluation conference, provides data on which research teams 'scored' highly against the evaluation criteria and the relationship between 'top scoring' teams at TRECVid and the 'top scoring' papers in terms of citations is analyzed. A strong relationship was found between 'success' at TRECVid and 'success' at citations both for high scoring and low scoring teams. The implications of the study in terms of the value of TRECVid as a research activity, and the value of bibliometric analysis as a research evaluation tool, are discussed.
