Analyst-Focused Arabic Information Retrieval, Robert N. Oddy, Ann R. Diekema, Jean Hannouche, Elizabeth Liddy, Grant Ingersoll

An English-Arabic Cross-Language Information Retrieval Environment was created in which the analyst can query an Arabic database in English and retrieve a set of relevant Arabic documents. The retrieved Arabic documents are automatically translated into English to facilitate readability by the English-only analyst. Proper names of people, places, and organizations are extracted from the retrieved documents and transliterated from Arabic into English. They are presented to the analyst and serve to provide a brief summarization of the retrieved document search query in English. Cross-Language Information Retrieval (CLIR), itself a desideratum in the ARDA workshop, is a special case of Information …
Discourse-Level Analysis Of Abstracts For Information Retrieval: A Probabilistic Approach, Robert N. Oddy
Discourse-Level Analysis Of Abstracts For Information Retrieval: A Probabilistic Approach, Robert N. Oddy
School of Information Studies - Faculty Scholarship
The objective of this research is to contribute to our knowledge of how people seek information, and how computer systems can be designed to help in this process. Most information retrieval research since the field emerged in the 1950's has reduced these questions to that of trying to determine how documents relevant to a user's query might be selected from a large collection of texts---a question that has proved remarkably difficult to answer. The present work takes the stance that this particular reduction increasingly limits progress towards the objective stated above. It is directed instead towards the development of a …
Towards The Use Of Situational Information In Information Retrieval, Robert N. Oddy, Elizabeth D. Liddy, Ann Bishop, Eileen Martin, Joseph Elewononi, Bhaskaran Balakrishnan

This paper is an exploratory study of one approach to incorporating situational information into information retrieval systems, drawing on principles and methods of discourse linguistics. A tenet of discourse linguistics is that texts of a specific type possess a structure above the syntactic level, which follows conventions known to the people using such texts to communicate. In some cases, such as literature describing work done, the structure is closely related to situations, and may therefore be a useful representational vehicle for the present purpose. Abstracts of empirical research papers exhibit a well-defined discourse- level structure, which is revealed by lexical …
Pthomas: An Adaptive Information Retrieval System On The Connection Machine., Robert Oddy, Bhaskaran Balakrishnan
Pthomas: An Adaptive Information Retrieval System On The Connection Machine., Robert Oddy, Bhaskaran Balakrishnan
School of Information Studies - Faculty Scholarship
This paper reports the state of development of PThomas, a network based document retrieval system implemented on a massively parallel fine-grained computer, the Connection Machine. The program is written in C*, an enhancement of the C programming language which exploits the parallelism of the Connection Machine. The system is based on Oddy’s original Thomas program, which was highly parallel in concept, and makes use of the Connection Machine’s single instruction multiple data (SIMD) processing capabilities. After an introduction to systems like Thomas, and their relationship to spreading activation and neural network models, the current state of PThomas is described, including …
Ask For Information Retrieval: Part Ii. Results Of A Design Study, Robert N. Oddy, N J. Belkin, H M. Brooks
Ask For Information Retrieval: Part Ii. Results Of A Design Study, Robert N. Oddy, N J. Belkin, H M. Brooks
School of Information Studies - Faculty Scholarship
In 'ASK for Information Retrieval: Part P1, we discussed the theory and background to a design study for an information retrieval (IR) system based on the attempt to represent the anomalous states of knowledge (ASKs) underlying information needs. In Part 11, we report the methods and results of the design study, and our conclusions.

We report the results of a British Library Research and Development Department funded design study for an interactive information retrieval system which will determine structural representations of the anomalous states of knowledge (ASKs) underlying information needs, and attempt to resolve the anomalies through a variety of retrieval strategies performed on a database of documents represented in compatible structural formats. Part I discusses the background to the project and the theory underlying it, Part II (next issue) presents our methods, results and conclusions. Basic premises of the project were: that information needs are not in principle precisely specifiable; that it is …
