- Abstract
- This study examined Library of Congress Classification (LCC)-based class numbers assigned to a representative sample of 200 titles in 52 American library systems to determine the level of consistency within and across those systems. The results showed that under the condition that a library system has a title, the probability of that title having the same LCC-based class number across library systems is greater than 85 percent. An examination of 121 titles displaying variations in class numbers among library systems showed certain titles (for example, multi-foci titles, titles in series, bibliographies, and fiction) lend themselves to alternate class numbers. Others were assigned variant numbers either due to latitude in the schedules or for reasons that cannot be pinpointed. With increasing dependence on copy cataloging, the size of such variations may continue to decrease. As the preferred class number with its alternates represents a title more fully than just the preferred class number, this paper argues for continued use of alternates by library systems and for finding a method to link alternate class numbers to preferred class numbers for enriched subject access through local and union catalogs.

- Abstract
- Pauline Atherton Cochrane has been contributing to library and information science for fifty years. Think of it-from mid-century to the millennium, from ENIAC (practically) to Internet 11 (almost here). What a time to be in our field! Her work an indexing, subject access, and the user-oriented approach had immediate and sustained impact, and she continues to be one of our most heavily cited authors (see, JASIS, 49[4], 327-55) and most beloved personages. This introduction includes a few words about my own experiences with Pauline as well as a short summary of the contributions that make up this tribute. A review of the curriculum vita provided at the end of this publication Shows that Pauline Cochrane has been involved in a wide variety of work. As Marcia Bates points out in her note (See below), Pauline was (and is) a role model, but I will always think of her as simply the best teacher 1 ever had. In 1997, I entered the University of Illinois Graduate School of Library and Information Science as a returning mid-life student; my previous doctorate had not led to a full-time job and I was re-tooling. I was not sure what 1 would find in library school, and the introductory course attended by more than 100 students from widely varied backgrounds had not yet convinced me I was in the right place. Then, one day, Pauline gave a guest lecture an the digital library in my introductory class. I still remember it. She put up some notes-a few words clustered an the blackboard with some circles and directional arrows-and then she gave a free, seemingly extemporaneous, but riveting narrative. She set out a vision for ideal information exchange in the digital environment but noted a host of practical concerns, issues, and potential problems that required (demanded!) continued human intervention. The lecture brought that class and the entire semester's work into focus; it created tremendous excitement for the future of librarianship. 1 saw that librarians and libraries would play an active role. I was in the right place.

- Abstract
- Classification is the process of assigning objects to pre-defined classes based on observations or characteristics of those objects, and there are many approaches to performing this task. The overall objective of this study is to demonstrate the use of two learning techniques to analyze the results of a manual classification system. Our sample consisted of 1,026 documents, from the ACM Computing Classification System, classified by their authors as belonging to one of the groups of the classification system: "H.3 Information Storage and Retrieval." A singular value decomposition of the documents' weighted term-frequency matrix was used to represent each document in a 50-dimensional vector space. The analysis of the representation using both supervised (decision tree) and unsupervised (clustering) techniques suggests that two pairs of the ACM classes are closely related to each other in the vector space. Class 1 (Content Analysis and Indexing) is closely related to Class 3 (Information Search and Retrieval), and Class 4 (Systems and Software) is closely related to Class 5 (Online Information Services). Further analysis was performed to test the diffusion of the words in the two classes using both cosine and Euclidean distance.

- Abstract
- A fuzzy set is a class of objects with a continuum of grades of membership. Such a set is characterized by a membership (characteristic) function which assigns to each object a grade of membership ranging between zero and one. The notions of inclusion, union, intersection, complement, relation, convexity, etc., are extended to such sets, and various properties of theses notions in the context of fuzzy sets are established. In particular, a separation theorem for convex fuzzy sets is proved without requiring that the fuzzy sets be disjoint

- Abstract
- This paper presents a study conducted at the University of Colorado at Boulder (CU-Boulder) to assess the extent to which its catalogers were using Classification Web (Class Web), the subscription-based, online cataloging documentation resource provided by the Library of Congress. In addition, this paper will explore assumptions made by management regarding CU-Boulder catalogers' use of the product, possible reasons for the lower-than-expected use, and recommendations for promoting a more efficient and cost-effective use of Class Web at other institutions similar to CU-Boulder.

- Abstract
- Shows how class-based object-oriented systems can be extended to handle evolving objects. Class hierarchies are complemented by role hierarchies, whose nodes represent role types that an object classified in the root may take on. At any point in time, an entity is represented by an instance of the root and an instance of every role type whose role it curently plays. In a natural way, the approach extends traditional object oriented concepts, such as classification, object identity, specialization, inheritance, and polymorphism in a natural way. Demonstartes the practicability of the approach by an implementation in Smalltalk. Roles can be provided in Smalltalk by adding a few classes. There is no need to modify the semantics of Smalltalk itself. Role hierarchies are mapped transparently onto ordinary classes. The presented implementation can easily be ported to object-oriented database programming languages based on Smalltalk such as Gemstone's OPAL

- Abstract
- An electronic classroom with computer workstations and multimedia offers tremendous potential for interactive instruction. To support such instruction, HyperCourseware was developed as an environment and authoring system that recreates on a computer network familiar objects of instruction, such as the syllabus, lecture notes, class rolls, seating chats, exams, and grade lists. In addition, it provides interactive and collaborative tools for group discussion, anonymous feedback, student polling, and shared collaborative wirkspaces. Applications in statistics and cognitve psychology are discussed along with the specific advantages due to hypermedia links, structure of course materials, integration of parts, and classroom interactivity. Student and faculty evaluation have supported the positive educational benefits of both the electronic classroom and HyperCourseware in general

- Abstract
- Any classification describes some structure of taxons on a subject field. Thus, one of the natural aspects of a classification theory is the study of possible taxon structure types. In particular, two classifications generating isomorphic taxon structures (regardless of size or how filled they are) could quite rightly be said to be of the same type. Let us formulate this situation in precise terms. Assume M is the subject field of the classification (the class of all objects to be classified). We use T to denote the set of taxon subclasses identified by the classificational features. On taxon set T the is a natural order of inclusion

- Abstract
- A major class of the requests from image database users involves similarity based retrieval for finding images spatially similar to a query image. Proposes an algorithm for computing the spatial similarity between 2 symbolic images. A symbolic image is a logical representation of the original image where the image objects are uniquely labelled with symbolic names. The algorithm can deal with translation, scale and rotational variance in images. Compares the characteristics of the proposed algorithm with those previously available by using a testbed of images. The proposed algorithm is more efficient and provides a rank ordering consistently matching with an expert

- Abstract
- Presents an integrated approach to image retrieval that makes use of both image and text features. Uses objects in the image and their locations as image features which are derived semi-automatically. Defines a similarity measure which combines the result of image and text query matching, and which considers the relative importance of each to the user. Moreover, the image matching considers the spatial similarity between a query object and an image object. Uses standard techniques for text indexing and matching. Provides a multimodal query interface by which users can retrieve pictures based on image or text or both. ELCAIR, an extensible class library for information retrieval, provides the basis for the resultant picture indexing and retrieval system

- Abstract
- A database management system is a general-purpose software system that facilitates the processes of defining, constructing, and manipulating databases for various applications. This article investigates the role of data management in multimedia digital libraries, and its implications for the design of database management systems. The notions of content abstraction and content independence are introduced, which clearly expose the unique challenges (for database architecture) of applications involving multimedia search. A blueprint of a new class of database technology is proposed, which supports the basic functionality for the management of both content and structure of multimedia objects

- Abstract
- We describe approaches and techniques for indexing and retrieving still images from multimedia databases. We specifically emphasize content-based image retrieval (CBIR), a class of techniques where the user composes queries that specify the content of the desired images. After a brief overview of digital image formats, we analyze different approaches to content specification: in terms of low-level visual features, of objects, and of metadata. We then describe a general progressive framework that combines these approaches. We finally conclude the entry with an overview of common applications of image repositories and digital libraries, such as medical imaging, remote-sensing imaging, and data for the oil industry.
