Knowledge, Practices, and Challenges of Library Practitioners on Abstracting

Access is the primary concern of a library thus information retrieval tool like an abstract is as important as the Online Public Access Catalog. Abstracting then plays an important role in improving access to information that is needed by library users. Librarians then perform this task primarily to guide the users in deciding whether an information resource will be consulted or not. The study utilized the descriptive method of research using a survey questionnaire to determine the level of knowledge and practices on the parts and types of abstracts and the challenges on abstracts a document surrogate encountered by library practitioners in selected parts of Northern Luzon, Philippines. The study found out that the library practitioners exhibited a high knowledge and practice on abstracting which can be attributed to their undergraduate studies specifically in the core major subject, indexing and abstracting. However, they enumerated challenges such as: 1) lack of time to carry out their abstracting function; 2) lack of policies and procedures in abstracting; 3) lack of manpower to do the job; 4) lack of motivation to perform the task; and 5) abstract is not a concern of most faculty and students. On the other hand, abstracts continue to be useful to the academic and research community and that library practitioners must find time to create or innovate ways of abstracting important documents useful to their users

Collaborative tagging as a knowledge organisation and resource discovery tool

The purpose of the paper is to provide an overview of the collaborative tagging phenomenon and explore some of the reasons for its emergence. Design/methodology/approach - The paper reviews the related literature and discusses some of the problems associated with, and the potential of, collaborative tagging approaches for knowledge organisation and general resource discovery. A definition of controlled vocabularies is proposed and used to assess the efficacy of collaborative tagging. An exposition of the collaborative tagging model is provided and a review of the major contributions to the tagging literature is presented. Findings - There are numerous difficulties with collaborative tagging systems (e.g. low precision, lack of collocation, etc.) that originate from the absence of properties that characterise controlled vocabularies. However, such systems can not be dismissed. Librarians and information professionals have lessons to learn from the interactive and social aspects exemplified by collaborative tagging systems, as well as their success in engaging users with information management. The future co-existence of controlled vocabularies and collaborative tagging is predicted, with each appropriate for use within distinct information contexts: formal and informal. Research limitations/implications - Librarians and information professional researchers should be playing a leading role in research aimed at assessing the efficacy of collaborative tagging in relation to information storage, organisation, and retrieval, and to influence the future development of collaborative tagging systems. Practical implications - The paper indicates clear areas where digital libraries and repositories could innovate in order to better engage users with information. Originality/value - At time of writing there were no literature reviews summarising the main contributions to the collaborative tagging research or debate

NASA automatic subject analysis technique for extracting retrievable multi-terms (NASA TERM) system

Current methods for information processing and retrieval used at the NASA Scientific and Technical Information Facility are reviewed. A more cost effective computer aided indexing system is proposed which automatically generates print terms (phrases) from the natural text. Satisfactory print terms can be generated in a primarily automatic manner to produce a thesaurus (NASA TERMS) which extends all the mappings presently applied by indexers, specifies the worth of each posting term in the thesaurus, and indicates the areas of use of the thesaurus entry phrase. These print terms enable the computer to determine which of several terms in a hierarchy is desirable and to differentiate ambiguous terms. Steps in the NASA TERMS algorithm are discussed and the processing of surrogate entry phrases is demonstrated using four previously manually indexed STAR abstracts for comparison. The simulation shows phrase isolation, text phrase reduction, NASA terms selection, and RECON display

Reflections on the documentary abstract and it?s practice: revision and systematization of theoreticalpractical approaches

[Resumen] Se realiza una categorización de los estudios del resumen documental a partir de la revisión de los diferentes modelos y propuestas de los investigadores en este campo. Se señala la evolución de la investigación en esta actividad de tratamiento documental de contenido, atendiendo a las aproximaciones de la textolingüística y el estructuralismo lingüístico, los enfoques semióticos, las orientaciones de la psicología cognitiva, o el funcionalismo sociointeraccional. Para ello, se establecen distintas etapas, que van desde los postulados precientíficos iniciales hacia avances metateóricos y procedimentales más complejos y dinámicos. Las nuevas orientaciones y tendencias son clasificadas en base a tres dimensiones: el enfoque del texto/producto, el enfoque del proceso-actividad resumidora y la aproximación comunicativo-sociocultural, como puente integrador entre ambos. Finalmente, se alude a una fusión necesaria de las teorías resumidoras existentes para configurar un mapa consolidado de modelos resumidores en distintos ámbitos de especialidad.[Abstract] We elaborate a study of the documentary abstract´s categorisation based on the revision of the different models the investigators in this field´s proposal. In this paper it is indicated the evolution of the investigation about the activity of the documentary treatment focusing on content. This research is developing through various interdisciplinary approaches, such as, textolingüístique approache, linguistic estructuralism approach, semiotic approach, including mental psychology orientation, and sociointeractional functionalism. In order to achieve the purpose, different stages are established: starting from the initial pre-scientific proposals which postulated towards the more complex and dynamic metatheoretical and procedural advances. The new directions and tendencies are classified on the basis of three dimensions: text/ product approach, abstracting process-activity approach and the communicative-sociocultural approach, as the integrating bridge between both. Finally, it guide to a necessary fusion of the existing summarizing theories in order to form a consolidated map of abstracting models in different scopes of specialty
