Cross-Language Retrieval For Arabic Texts: The Creation Of An English-Arabic Cross-Language Information Retrieval Environment, Robert N. Oddy, Anne R. Diekema, Jean Hannouche, Grant Ingersoll, Elizabeth D. Liddy Jan 2005

Cross-Language Retrieval For Arabic Texts: The Creation Of An English-Arabic Cross-Language Information Retrieval Environment, Robert N. Oddy, Anne R. Diekema, Jean Hannouche, Grant Ingersoll, Elizabeth D. Liddy

Robert Oddy

An English-Arabic Cross-Language Information Retrieval Environment was created in which the user can query an Arabic database in English and retrieve a set of relevant Arabic documents. The retrieved Arabic documents will be automatically translated into English to facilitate readability by the English language user. Proper names of people, places, and organizations are extracted from the retrieved documents and transliterated from Arabic into English. They are presented to the user and serve to provide a brief summarization of the retrieved document. Another feature of the AIR design is the user’s ability to group searches and search results into what we …


Analyst-Focused Arabic Information Retrieval, Robert N. Oddy, Ann R. Diekema, Jean Hannouche, Elizabeth Liddy, Grant Ingersoll Jan 2005

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

Robert Oddy

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 …


An Application Of Plausible Reasoning To Information Retrieval, Farhad Oroumchian, Robert N. Oddy Jan 1996

An Application Of Plausible Reasoning To Information Retrieval, Farhad Oroumchian, Robert N. Oddy

Robert Oddy

This work explores the use of plausible inferences as a means of retrieving relevant documents. Collins and Michalski’s theory of plausible reasoning has been modified to accommodate information retrieval. Methods are proposed to represent document contents by logical terms and statements, and queries by incomplete logical statements. Extensions to plausible inferences are discussed. Two versions of the extended plausible reasoning system were implemented, one using dominance weights (described in the paper) and the other using tf. Idf (Term Frequency Inverse Document Frequency) weights. Experiments were conducted using the titles and abstracts of the CACM collection and it was found that …


Discourse-Level Analysis Of Abstracts For Information Retrieval: A Probabilistic Approach, Robert N. Oddy Jul 1992

Discourse-Level Analysis Of Abstracts For Information Retrieval: A Probabilistic Approach, Robert N. Oddy

Robert Oddy

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 Jan 1992

Towards The Use Of Situational Information In Information Retrieval, Robert N. Oddy, Elizabeth D. Liddy, Ann Bishop, Eileen Martin, Joseph Elewononi, Bhaskaran Balakrishnan

Robert Oddy

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 Jan 1991

Pthomas: An Adaptive Information Retrieval System On The Connection Machine., Robert Oddy, Bhaskaran Balakrishnan

Robert Oddy

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 Sep 1982

Ask For Information Retrieval: Part Ii. Results Of A Design Study, Robert N. Oddy, N J. Belkin, H M. Brooks

Robert Oddy

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.


Ask For Information Retrieval: Part I. Background And Theory, Robert N. Oddy, N J. Belkin, H M. Brooks Jun 1982

Ask For Information Retrieval: Part I. Background And Theory, Robert N. Oddy, N J. Belkin, H M. Brooks

Robert Oddy

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 …


Information Retrieval Through Man-Machine Dialogue., Robert N. Oddy Jan 1977

Information Retrieval Through Man-Machine Dialogue., Robert N. Oddy

Robert Oddy

The purpose of this paper is to introduce a new method of information retrieval by man-machine interaction. The dialogue supported has more symmetry than most interactive computer systems in that the machine forms an image (rather as a man does) of the view of the human enquirer, without requiring him to ask a precise question, and responds with references according to its image. Initial tests with a prototype program indicate that a performance equal to that obtainable from a more conventional on-line retrieval system is possible without obliging the user to formulate his query.


Reference Retrieval Based On User Induced Dynamic Clustering., Robert N. Oddy Dec 1974

Reference Retrieval Based On User Induced Dynamic Clustering., Robert N. Oddy

Robert Oddy

The problem of mechanically retrieving references to documents, as a first step to fulfilling the information need of a researcher, is tackled through the design of an interactive computer program. A view of reference retrieval is presented which embraces the browsing activity. In fact, browsing is considered important and regarded as ubiquitous. Thus, for successful retrieval (in many circumstances), a device which permits conversation is needed. Approaches to automatic (delegated) retrieval are surveyed, as are on-line systems which support interaction. This type of interaction usually consists of iteration, under the user's control, in the query formulation process. A program has …
