Abstract

The system is available both in print and online versions. Names a few new subject headings in areas like science, technology, engineering and medicine (STEM). In this edition, there are a total of 1,600 new headings making it a total of 12,000+ preferred headings meant for subject access in small and medium sized libraries. This unprecedented increase of about 1,600 headings is mostly due the complete incorporation of the Canadian Sears last published independently in 2006. Also critically examines inconsistencies in a few headings. Concludes to say the new edition in resplendent, hard binding maintains its stellar reputation of a handy list of general subject headings both for applications and a teaching resource.

Abstract

The Nuovo Soggettario is a subject indexing system edited by the Biblioteca Nazionale Centrale di Firenze. It was presented to librarians from across Italy on 8 February 2007 in Florence as a new edition of the Soggettario (1956), and it has become the official Italian subject indexing tool. This system is made up of two individual and interactive components: the general thesaurus, accessible on the web since 2007 and the rules of a conventional syntax for the construction of subject strings. The Nuovo soggettario thesaurus has grown significantly in terms of terminology and connections with other knowledge organization tools (e.g., encyclopedias, dictionaries, resources of archives and museums, and other information data sets), offering the users the possibility to browse through documents, books, objects, photographs, etc. The conversion of the Nuovo soggettario thesaurus into formats suitable for the semantic web and linked data world improves its function as an interlinking hub for direct searching and for organizing content by different professional communities. Thanks to structured data and the SKOS format, the Nuovo soggettario thesaurus is published on the Data Hub platform, thus giving broad visibility to the BNCF and its precious patrimony.

Abstract

This article argues that the use of the Library of Congress subject heading "East Indians" in reference to individuals from India represents not only a problematic vestige of colonialism, but also a failure of the principle of literary warrant. It provides an overview of the term's historical roots and then examines whether the term is still widely used in published resources. Although assigning a subject heading is not easy and can involve a choice between contested realities of diverse peoples, the author contends that a rejection of outdated terminology is central to providing any culturally sensitive tool for resource organization.

Abstract

A commonly used technique for improving search engine performance is result caching. In result caching, precomputed results (e.g., URLs and snippets of best matching pages) of certain queries are stored in a fast-access storage. The future occurrences of a query whose results are already stored in the cache can be directly served by the result cache, eliminating the need to process the query using costly computing resources. Although other performance metrics are possible, the main performance metric for evaluating the success of a result cache is hit rate. In this work, we present a machine learning approach to improve the hit rate of a result cache by facilitating a large number of features extracted from search engine query logs. We then apply the proposed machine learning approach to static, dynamic, and static-dynamic caching. Compared to the previous methods in the literature, the proposed approach improves the hit rate of the result cache up to 0.66%, which corresponds to 9.60% of the potential room for improvement.

Abstract

The Association for Manitoba Archives has created a database where members can deposit archival descriptions to provide a central search for users. Library of Congress Subject Headings (LCSH) were chosen as the controlled subject vocabulary to use in the descriptions, but changes were made to LCSH to better describe material about or by Indigenous peoples. Examples include: the word "Indian"; geographic place embedded in terms such as "Indians of North America"; changes related to Manitoba peoples specifically; and miscellaneous changes not part of a larger pattern. New terms were also added.

Abstract

With the current information environment characterized by the proliferation of digital resources, including collaboratively created and shared resources, Library of Congress Subject Headings (LCSH) is facing the challenges of effective and efficient subject-based organization and retrieval of digital resources. To explore the feasibility of utilizing LCSH in a digital environment, we might need to revisit its basic characteristics. The objectives of our study were to analyze LCSH in both syntactic and relational structures, to discover the structural characteristics of LCSH, and to identify problems and issues for the feasibility of LCSH as an effective subject access tool. This study reports and discusses issues raised by the syntactic and hierarchical structures of LCSH that present challenges to its use in a networked environment. Given the results of this study, we recommend a number of provisional future directions for the development of LCSH towards further becoming a viable system for digital and networked resources.

Abstract

This writeup presents the fundamentals of subject indexing in terms of its development, scope, coverage, role in subject indexing techniques and the important elements to design a well-structured and effective subject indexing process, requirements and the infrastructure. From the time of RDC to PRECIS, the developers has been envisaged the problems to expand the flexibility and versatility of indexing technique. Whenever one indexing process is failed to achieve the maximum efficiency another is developed on the basis of failure. It concludes that all the developments of subject indexing processes during that era are leads to the innovation of Artificial Intelligence technique (AI), i.e. Natural Language Processing (NLP) by implementation of Information and Communication Technology (ICT) in present time.

Rez. in: KO 38(2011) no.4, S.360-361 (M.P. Satija): "The 20th edition of the celebrated Sears List (1sted.1923) published in June 2010 sets a new cycle of three year revision. Earlier it was three and a half years to synchronize with the publication of the new edition of the Abridged Dewey revised after every seven years. In the days of constantly updated WebDewey, it is no more a constraint. For the first time Sears List has been released simultaneously in online database format accessible to licensed subscribers. Responding to the environmental changes the basic edition is the online one whose content is designed in MARC authority. Print edition is now a derivative of the MARC data. The editors keep tabs on the changing information seeking behavior of users and how OPACs are accessed; yet the editors or the publishers never discuss the mechanisms of designing a new edition. The new edition features more than 300 new subject headings suggested by librarians from different types of libraries, vendors of bibliographic records, indexers and subject specialists at the H.W. Wilson Company. Every new edition incorporates advances in vocabulary control, changing approaches of library users for subject access and even in the worldwide use of the English language. Each edition of the Sears List strengthens and continues the policies and consolidates the reforms that began with the 15th edition (1994). It is indeed an era of innovations in Sears. The latest knowledge from information science and information seeking behavior has been deployed to modernize the internal structure and grammar of the Sears List. Continuing adaptation constitutes the key to its success and popularity in the shifting sands of the information-seeking behavior of users. But the List is still a living manifestation of the principles of subject cataloguing put forth by C.A. Cutter (1837-1903).
. . . To summarize, as usual the List continues to provide complete guidance for the subject cataloguers for the maintenance of catalogues, for addition of new headings, and revision of the old ones. Its Introduction is clear and well illustrated, so much so that not only it is an illustrated operational manual to the Sears but also a concise textbook to teach principles and theory of the subject headings. Due to its affordable price and portability it is used to teach basics of subject headings in first year of Knowledge Organization courses. It also acts as an excellent and easy index to the DDC (Weihs 2004). The new edition should be welcome both for subject cataloguers and for teachers of subject cataloguing work."
