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

School of Information Studies - Faculty Scholarship

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 …

Enabling Dynamic Market-Managed Qos Interconnection In The Next Generation Internet By A Modified Bgp Mechanism, Junseok Hwang, Jorn Altmann, Huw Oliver, Alfonso Suarez Jan 2002

Enabling Dynamic Market-Managed Qos Interconnection In The Next Generation Internet By A Modified Bgp Mechanism, Junseok Hwang, Jorn Altmann, Huw Oliver, Alfonso Suarez

School of Information Studies - Faculty Scholarship

We propose a market-managed QoS (Quality of Service) interconnection model for heterogeneous networking environments. The deployment of this model will help autonomous systems to reduce the cost of their network services as well as increase social welfare. We describe a technical solution for a next generation Internet, where networks are managed based on either technology requirements (QoS networks) or market principles (market-managed networks). Our solution requires two technologies: BMP (Bandwidth Management Point) and a modified version of BGP (Border Gateway Protocol). The modified version of BGP, as proposed in this paper, provides additional routing exchange information such as price and …

Exploring Strengths And Limits On Open Source Software Engineering Processes: A Research Agenda, Kevin Crowston, Barbara Scozzi Jan 2002

Exploring Strengths And Limits On Open Source Software Engineering Processes: A Research Agenda, Kevin Crowston, Barbara Scozzi

School of Information Studies - Faculty Scholarship

Many researchers have investigated the nature and characteristics of open source software (OSS) projects and their developer communities. In this position paper, after examining some success factors, we discuss potential limits on the replicability and portability of OSS engineering processes. Based on this analysis, we propose a research agenda to better understand the current nature of the processes and thus the strengths and the limitations.

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

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 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

School of Information Studies - Faculty Scholarship

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

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 Sep 1982

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.

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

School of Information Studies - Faculty Scholarship

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 …
