- 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
- 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
- Proposes an uniform indexing scheme for enhancing object-oriented databases performance. It is based on a single B-tree and combines both the hierarchical and nested indexing schemes. the uniformity of this scheme enables compact and optimised code for dealing with a large range of queries on the one hand, and flexibility in adding and removing indexed paths on the other hand. Discusses the performance and presents an extensive experimental analysis for the class-hierarchy case. The results show the advantages of the scheme for small range, clustered sets queries

- Abstract
- In this article recording evidence for data values in addition to the values themselves in bibliographic records and descriptive metadata is proposed, with the aim of improving the expressiveness and reliability of those records and metadata. Recorded evidence indicates why and how data values are recorded for elements. Recording the history of changes in data values is also proposed, with the aim of reinforcing recorded evidence. First, evidence that can be recorded is categorized into classes: identifiers of rules or tasks, action descriptions of them, and input and output data of them. Dates of recording values and evidence are an additional class. Then, the relative usefulness of evidence classes and also levels (i.e., the record, data element, or data value level) to which an individual evidence class is applied, is examined. Second, examples that can be viewed as recorded evidence in existing bibliographic records and current cataloging rules are shown. Third, some examples of bibliographic records and descriptive metadata with notes of evidence are demonstrated. Fourth, ways of using recorded evidence are addressed.

- Abstract
- The paper discusses the challenges of faceted vocabulary organization in universal classifications which treat the universe of knowledge as a coherent whole and in which the concepts and subjects in different disciplines are shared, related and combined. The authors illustrate the challenges of the facet analytical approach using, as an example, the revision of class 72 in UDC. The paper reports on the research undertaken in 2013 as preparation for the revision. This consisted of analysis of concept organization in the UDC schedules in comparison with the Art & Architecture Thesaurus and class W of the Bliss Bibliographic Classification. The paper illustrates how such research can contribute to a better understanding of the field and may lead to improvements in the facet structure of this segment of the UDC vocabulary.

- Abstract
- Describes an object-oriented model for paper-based multimedia documents such as textbook with embedded graphics. This model is the 1st step towards building a manageable authoring system for the Web, in which documents can be easily built, extended, truncated, reordered, assembled and disassembled on a computer basis, and the document components, can be reused. The model will also make accessible properties, which might be significant or important to the user, especially in searching or classifying documents, such as the document title and author. Explains the model design and presents the class hierarchy for the model

- Abstract
- Studies relevance relations in the context of propositional logical theories and subject matters or topics of interest, which are taken to be sets of atomic propositions. Introduces the class of regular belief models and a notion of prime implicates applicable to all forms of this type of belief. Introduces implicit belief, which has a classical possible world model. discusses definitions of relevance for regular belief using implicit belief as a running example. Focuses on connections between relevance under implicit belief and work in the literature and computational aspects. Discusses relevance under explicit belief, which is based on a 3 valued extension of possible world semantics

- Abstract
- In text categorization tasks, classification on some class hierarchies has better results than in cases without the hierarchy. Currently, because a large number of documents are divided into several subgroups in a hierarchy, we can appropriately use a hierarchical classification method. However, we have no systematic method to build a hierarchical classification system that performs well with large collections of practical data. In this article, we introduce a new evaluation scheme for internal node classifiers, which can be used effectively to develop a hierarchical classification system. We also show that our method for constructing the hierarchical classification system is very effective, especially for the task of constructing classifiers applied to hierarchy tree with a lot of levels.

- Abstract
- Effective patent management is essential for organizations to maintain their competitive advantage. The classification of patents is a critical part of patent management and industrial analysis. This study proposes a hybrid-patent-classification approach that combines a novel patent-network-based classification method with three conventional classification methods to analyze query patents and predict their classes. The novel patent network contains various types of nodes that represent different features extracted from patent documents. The nodes are connected based on the relationship metrics derived from the patent metadata. The proposed classification method predicts a query patent's class by analyzing all reachable nodes in the patent network and calculating their relevance to the query patent. It then classifies the query patent with a modified k-nearest neighbor classifier. To further improve the approach, we combine it with content-based, citation-based, and metadata-based classification methods to develop a hybrid-classification approach. We evaluate the performance of the hybrid approach on a test dataset of patent documents obtained from the U.S. Patent and Trademark Office, and compare its performance with that of the three conventional methods. The results demonstrate that the proposed patent-network-based approach yields more accurate class predictions than the patent network-based approach.

- Abstract
- The structure of a classification system contributes in a variety of ways to representing semantic relationships between its topics in the context of subject authority control. We explore this claim using the Dewey Decimal Classification (DDC) system as a case study. The DDC links its classes into a notational hierarchy, supplemented by a network of relationships between topics, expressed in class descriptions and in the Relative Index (RI). Topics/subjects are expressed both by the natural language text of the caption and notes (including Manual notes) in a class description and by the controlled vocabulary of the RI's alphabetic index, which shows where topics are treated in the classificatory structure. The expression of relationships between topics depends on paradigmatic and syntagmatic relationships between natural language terms in captions, notes, and RI terms; on the meaning of specific note types; and on references recorded between RI terms. The specific means used in the DDC for capturing hierarchical (including disciplinary), equivalence and associative relationships are surveyed.

- Abstract
- An expansion of the MARC codes for decimal class numbers is recommended, in order to enhance automated subject retrieval. Five values for a second indicator and two new subfields are suggested for encoding hierarchical relationships among decimal class numbers. Six additional subfields are suggested, in order to analyze synthesized class numbers
