Internet-Scale code retrieval deals with the representation, storage, and access of relevant source code from a large amount of source code available on the Internet. Internet-Scale code retrieval systems support common emerging practices among software developers related to finding and reusing source code. In this dissertation we focus on some…

Signal detection is a challenging task for regulatory and intelligence agencies. Subject matter experts in those agencies analyze documents, generally containing narrative text in a time bound manner for signals by identification, evaluation and confirmation, leading to follow-up action e.g., recalling a defective product or public advisory for…

Radiology data, in the form of images and reports, is growing at a high rate due to the introduction of new imaging modalities, new uses of existing modalities, and the growing importance of objective image information in the diagnosis and treatment of patients. This increase has resulted in an enormous set of image data that is richly annotated…

The study of this dissertation provides a solution to a very specific problem instance in the area of data mining, data warehousing, and service-oriented architecture in publishing and newspaper industries. The research question focuses on the integration of data mining and data warehousing. The research problem focuses on the development of…

With the increasing wealth of information on the Web, information integration is ubiquitous as the same real-world entity may appear in a variety of forms extracted from different sources. This dissertation proposes supervised and unsupervised algorithms that are naturally integrated in a scalable framework to solve the entity resolution problem,…

With the dramatic growth of text information, there is an increasing need for powerful text mining systems that can automatically discover useful knowledge from text. Text is generally associated with all kinds of contextual information. Those contexts can be explicit, such as the time and the location where a blog article is written, and the…

Presents personal analysis of information science as a field of scientific inquiry and professional practice that has evolved over the past half-century. Examines origin of information science in respect to problems of the information explosion, social role of field, nature of "information," structure of field in terms of problems addressed,…

Several algorithms were investigated which would allow a user to interact with an automatic document retrieval system by requesting relevance judgments on selected sets of documents. Two viewpoints were taken in evaluation. One measured the movement of queries toward the optimum query as defined by Rocchio; the other measured the retrieval…

The idea of pseudo-classification based on external relevance was introduced and compared with the usual classifications using associative techniques. A general model for an information retrieval system using term classification was described. A set of operators for adjusting pseudo-classifications and preventing their deterioration was derived…

The application of computers to retrieval of primary documents is illustrated by descriptions of the Baltimore Region Institutional Studies Center (BRISC), which operates an automated system for retrieving records by subject, geographic location, and date; and ARCHON (ARCHives ONline), the online program developed to meet BRISC retrieval…

Rooted binary trees with weighted nodes are structures encountered in many areas, such as coding theory, searching and sorting, information storage and retrieval. The path length is a meaningful quantity which gives indications about the expected time of a search or the length of a code, for example. In this paper, two sharp bounds for the total…

Research in networking of heterogeneous interactive bibliographic retrieval systems is being conducted which centers on the concept of a virtual retrieval system. Such a virtual system would be created through a translating computer interface that would provide access to the different retrieval systems and data bases in a uniform and convenient…

Various aspects of computer and information science and librarianship are discussed, including the problem of foreign language material increasing in the U.S. and Canada. (SM)

This bibliography lists journal articles, conference papers, book chapters, theses, and instructional aids written by the staff of Project Intrex at Massachusetts Institute of Technology. A listing of presentations given but not available in manuscript is also included. The publications listed report results of research sponsored by the National…

This annual report of the Department of Computer and Information Science at Ohio State University for July 1977-June 1978 covers the department's organizational structure, objectives, highlights of department activities (such as grants and faculty appointments), instructional programs/course offerings, and facilities. In the second half of the…
