A comparative analysis of methods for estimating informatization efficiency in regional economic systems

Informatization is shown to be important at the regional level and influence information needs. The system of regional informatization consists of three main subsystems, including information needs, information potential, and infrastructure, which are presented in the form of a conceptual model. The existing methods for estimating informatization efficiency are considered; a hierarchic model of the system of factors used to estimate the level of regional informatization is developed.

Evolution of a processing system in a large biomedical library.

The processing system used in the UCLA Biomedical Library is modest in size and still under development. Its origins date back to a batch mode serials control system begun in the mid-1960s. This was converted to an on-line system which currently has modules for check-in, updating and retrieval, claims, bindery preparation, and invoice information. Titles can be retrieved at the terminal by search of any word in the title, by subject heading, language, country of publication, and type of publication. The system is adaptable to network use and at present is shared with one other library. To the serials system has been added a computer-assisted cataloging and card production system. The latter utilizes serials nucleus software as well as design for data input and data storage. In-house listings and coding procedures overlap in a general way. Work is under way on further integration of the two processing subsystems and a feasibility study has been completed for addition of a subsystem for acquisitions which will combine and adapt features of the other two; for example, information retrieval characteristics from both, catalog coding and programs for acceptance of data, serials programs for claims, and other output programs. Cost benefits of the subsystems are described and discussed.

��[Purpose/significance] As a special way of information acquisition behavior, researching the mechanism of information encountering can provide theoretical reference for the internal and external environment design that effectively promotes information encountering among research users, and rich information behavior research.[Method/process] This paper firstly analyzes the influencing factors model of information encountering under the process perspective, and then comprehends the causal relationship among factors affecting information encountering by means of system dynamics model. Also, this paper constructs the corresponding flow graph model, and explores the role of various influencing factors in the occurrence of information encountering through simulation analysis and quantitative form finally.[Result/conclusion] The scientific researchers' information encountering system under the process perspective mainly consists of three subsystems:user, information and context. Among them, personality characteristics, information quality levels and behavioral contexts can significantly promote information encountering, while mission context significantly inhibits the occurrence of information encountering.

Adaptive Filtering of Newswire Stories using Two-Level Clustering

Adaptive filtering of news is an area of information retrieval gaining substantial interest as services become more available on the Internet. This paper reports on a number of experiments involving a two-level clustering approach using a variety of techniques including threshold adaptation, topic vocabulary adaptation and both noun phrase and named entity adaptation. Our goal in this exploratory research is to empirically compare alternative configurations of our filtering approach that will allow us to better understand the relative value of the component subsystems.     

Copyright complicance in the electronic age: Conceptual issues

This article focuses on several conceptual and structural issues that are central to copyright compliance in the electronic age. It presumes the development of a national electronic network for storing, organizing, accessing, managing, and charging for information. The article first discusses the implications of constructing a comprehensive electronic “highway,” or Digital Library System (DLS), which would link information to the widespread community of users. It then presents the ramifications of a highly decentralized set of subsystems serving rights holders and users, linked by protocols established by the DLS. A discussion of the implications of digital interchangeability for copyright follows. The article ends with an analysis of alternatives to existing intellectual property rights conveyance systems, and concludes that current ownership structures, and systems for conveying rights and royalties, will remain the foundation for copyright in the electronic world. This article appeared in a slightly different form in theProceedings of the Twelfth National Online Meeting—1991, and is published here with the permission of Learned Information, Inc., Medford, N.J.     

An evolution of experts: MEDLINE in the library school.

Question: What is the real value that medical librarians bring to the health care environment? How have library science educators, frequently former practitioners themselves, responded to the challenge of expert searching?Methods: In this paper, I give an historical introduction to the landscape of medical information retrieval through the development of MEDLINE. I then look at the evolution of training in online searching and its place in the context of library school education and particularly the effect of generalist education on future specialists. Finally, I acknowledge the new role of the informationist as another assertion of our professional expertise.Conclusions: The three interdependent subsystems of our professional machine—our schools, our association, and our professional peers— must all respond to this challenge by asserting our expertise in our curricula, in our continuing education, and in our dialogues with each other. Only by acknowledging the interaction of these subsystems will real and positive changes be effected to benefit our profession and our constituencies.
