- Abstract
- We propose a novel approach to incorporate term similarity and inverse document frequency into a logical model of information retrieval. The ability of the logic to handle expressive representations along with the use of such classical notions are promising characteristics for IR systems. The approach proposed here has been efficiently implemented and experiments against test collections are presented.

- Abstract
- WorldCat, OCLC's bibliographic database, identifies books and the libraries that hold them. The holdings provide detailed information about the type and number of libraries that have acquired the material. Using this information, it is possible to infer the type of audience for which the material is intended. A quantitative measure, the audience level, is derived from the types of libraries that have selected the resource. The audience level can be used to refine discovery, analyze collections, advise readers, and enhance reference services.

- Abstract
- Survivors of intimate partner violence face more than information gaps; many face powerful barriers in the form of information myths. Triangulating data from in-depth interviews and community bulletin board postings, this study incorporates insights from survivors, police, and shelter staff to begin mapping the information landscape through which survivors move. An unanticipated feature of that landscape is a set of 28 compelling information myths that prevent some survivors from making effective use of the social, legal, economic, and support resources available to them. This analysis of the sources, contexts, and consequences of these information myths is the first step in devising strategies to counter their ill effects.

- Abstract
- The outputs of several information filtering (IF) systems can be combined to improve filtering performance. In this article the authors propose and explore a framework based on the so-called information structure (IS) model, which is frequently used in Information Economics, for combining the output of multiple IF systems according to each user's preferences (profile). The combination seeks to maximize the expected payoff to that user. The authors show analytically that the proposed framework increases users expected payoff from the combined filtering output for any user preferences. An experiment using the TREC-6 test collection confirms the theoretical findings.

- Abstract
- This article suggests that Information Architecture (IA) design is primarily an inductive process. Although toplevel goals, user attributes and available content are periodically considered, the process involves bottom-up design activities. IA is inductive partly because it lacks internal theory, and partly because it is an activity that supports emergent phenomena (user experiences) from basic design components. The nature of IA design is well described by Constructive Induction (CI), a design process that involves locating the best representational framework for the design problem, identifying a solution within that framework and translating it back to the design problem at hand. The future of IA, if it remains inductive or develops a body of theory (or both), is considered.

- Abstract
- User interfaces of Web search engines reflect attributes of the underlying tools used to create them, rather than what we know about how people look for information. In this article, the author examines several characteristics of user search behavior: the variety of information-seeking goals, the cultural and situational context of search, and the iterative nature of the search task. An analysis of these characteristics suggests ways that interfaces can be redesigned to make searching more effective for users.

- Abstract
- Most information systems share a common assumption: information seeking is discrete. Such an assumption neither reflects real-life information seeking processes nor conforms to the perspective of phenomenology, "life is a journey constituted by continuous acquisition of knowledge." Thus, this study develops and validates a theoretical model that explains successive search experience for essentially the same information problem. The proposed model is called Multiple Information Seeking Episodes (MISE), which consists of four dimensions: problematic situation, information problem, information seeking process, episodes. Eight modes of multiple information seeking episodes are identified and specified with properties of the four dimensions of MISE. The results partially validate MISE by finding that the original MISE model is highly accurate, but less sufficient in characterizing successive searches; all factors in the MISE model are empirically confirmed, but new factors are identified as weIl. The revised MISE model is shifted from the user-centered to the interaction-centered perspective, taking into account factors of searcher, system, search activity, search context, information attainment, and information use activities.

- Abstract
- Chemical information sciences-ranging from subjectspecific bibliometrics to sophisticated theoretical systems for modeling structures and reactions-have historically led in developing new technologies. Hundreds of papers are published or presented at conferences annually in this discipline. One of the more significant conferences at which important research has historically been presented is the Tri-Society Symposium an Chemical Information, an event jointly sponsored by the American Chemical Society, the American Society for Information Science and Technology, and the Special Libraries Association and held every four years. Eight years ago, the theme of this conference was the chemist's workstation; papers were presented an developments enabling chemists to access and process a variety of different types of chemical information from their desktop or laboratory bench. Several of these papers were subsequently published as a Perspectives issue.

- Abstract
- In a series of lectures presented in 1970, Pauline Cochrane offered an American view of Ranganathan's five laws of library science (Atherton, 1973). According to Cochrane, Ranganathan first con ceived of the five laws in 1924. They include: (1) books are for use; (2) every reader his book; (3) every book its reader; (4) save the time of the reader; and (5) a library is a growing organism. With respect to law 4, Cochrane cited the need for more research to understand the match between a user's information needs and the descriptions of information resources. In constructing the catalog and other search tools, do we save the time of the reader? Success in this effort requires knowing more about the reader's information needs and search behavior. Cochrane (1992) revisited the laws two decades later, recommending that they serve as guidelines and criteria for assessing the value of information technology in library and information services. In particular she suggested the need to determine whether information technology improves the timeliness, precision, and comprehensiveness of information provision to users. This article focuses an how information technology may enable us better to meet the needs of a particular category of information users - those undertaking interdisciplinary research. In a study completed twenty-five years ago, this author investigated the feasibility of developing a mapping of portions of controlled vocabularies as a tool for assisting in cross-database searching (Smith, 1974).

- Abstract
- The Specialized Information Services Division (SIS) of the National Library of Medicine (NLM) provides Web access to more than a dozen scientific databases on toxicology and the environment on TOXNET . Search queries on TOXNET often include misspelled or variant English words, medical and scientific jargon and chemical names. Following the example of search engines like Google and ClinicalTrials.gov, we set out to develop a spelling "suggestion" system for increased recall and precision in TOXNET searching. This paper describes development of dictionary technology that can be used in a variety of applications such as orthographic verification, writing aid, natural language processing, and information storage and retrieval. The design of the technology allows building complex applications using the components developed in the earlier phases of the work in a modular fashion without extensive rewriting of computer code. Since many of the potential applications envisioned for this work have on-line or web-based interfaces, the dictionaries and other computer components must have fast response, and must be adaptable to open-ended database vocabularies, including chemical nomenclature. The dictionary vocabulary for this work was derived from SIS and other databases and specialized resources, such as NLM's Unified Medical Language Systems (UMLS) . The resulting technology, A-Z Dictionary (AZdict), has three major constituents: 1) the vocabulary list, 2) the word attributes that define part of speech and morphological relationships between words in the list, and 3) a set of programs that implements the retrieval of words and their attributes, and determines similarity between words (ChemSpell). These three components can be used in various applications such as spelling verification, spelling aid, part-of-speech tagging, paraphrasing, and many other natural language processing functions.
