Aigaion: A Web-based Open Source Software for Managing the Bibliographic References

Jose, Sanjo, Jayakanth, Francis January 2008 (has links)
Publishing research papers is an integral part of a researcher's professional life. Every research article will invariably provide large number of citations/bibliographic references of the papers that are being cited in that article. All such citations are to be rendered in the citation style specified by a publisher and they should be accurate. Researchers, over a period of time, accumulate a large number of bibliographic references that are relevant to their research and cite relevant references in their own publications. Efficient management of bibliographic references is therefore an important task for every researcher and it will save considerable amount of researchers' time in locating the required citations and in the correct rendering of citation details. In this paper, we are reporting the features of Aigaion, a web-based, open-source software for reference management.

Tagging for health information organisation and retrieval

Kipp, Margaret E. I. January 2007 (has links)
This paper examines the tagging practices evident on CiteULike, a research oriented social bookmarking site for journal articles. Articles selected for this study were health information and medicine related. Tagging practices were examined using standard informetric measures for analysis of bibliographic information and analysis of term use. Additionally, tags were compared to descriptors assigned to the same article.

The impact of specificity on the retrieval power of a UDC-based multilingual thesaurus

Francu, Victoria January 2003 (has links)
The article describes the research done over a bibliographic database in order to show the impact the specificity of the knowledge organising tools may have on information retrieval. For this purpose two multilingual UDC-based thesauri having different degrees of specificity are considered. Issues of harmonising a classificatory structure with a thesaurus structure are introduced and significant aspects of information retrieval in a multilingual environment are argued in an extensive manner. Aspects of complementarity are discussed with particular emphasis on the real impact produced by alternative search facilities on IR. Finally a number of conclusions are formulated as they arise from the study.

Indexing and retrieving images in a multilingual world (extended abstract)

Ménard, Elaine January 2007 (has links)
The Internet constitutes a vast universe of knowledge and human culture, allowing the dissemination of ideas and information without borders. The Web also became an important media for the diffusion of multilingual resources. However, linguistic differences still form a major obstacle to scientific, cultural, and educational exchange. With the ever increasing size of the Web and the availability of more and more documents in various languages, this problem becomes all the more pervasive. Besides this linguistic diversity, a multitude of databases and collections now contain documents in various formats, which may also adversely affect the retrieval process. This paper presents the context, the problem statement, and the experiment carried out of a research project aiming to verify the existing relations between two different indexing approaches: (1) traditional image indexing recommending the use of controlled vocabularies or (2) free image indexing using uncontrolled vocabulary, and their respective performance for image retrieval, in a multilingual context. The use of controlled vocabularies or uncontrolled vocabularies raises a certain number of difficulties for the indexing process. These difficulties will necessarily entail consequences at the time of image retrieval. Indexing with controlled or uncontrolled vocabularies is a question extensively discussed in the literature. However, it is clear that many searchers recognize the advantages of either form of vocabulary according to circumstances (Arsenault, 2006). It appears that the many difficulties associated with free indexing using uncontrolled vocabularies can only be understood via a comparative analysis with controlled vocabulary indexing (Macgregor & McCulloch, 2006). This research compares image retrieval within two contexts: a monolingual context where the language of the query is the same as the indexing language; and a multilingual context where the language of the query is different from the indexing language. This research will indicate if one of these indexing approaches surpasses the other, in terms of effectiveness, efficiency, and satisfaction of the image searchers. For this research, three data collection methods are used: (1) the analysis of the vocabularies used for image indexing in order to examine the multiplicity of term types applied to images (generic description, identification, and interpretation) and the degree of indexing difficulty due to the subject and the nature of the image; (2) the simulation of the retrieval process with a subset of images indexed according to each indexing approach studied, and finally, (3) the administration of a questionnaire to gather information on searcher satisfaction during and after the retrieval process. The quantification of the retrieval performance of each indexing approach is based on the usability measures recommended by the standard ISO 9241-11, i.e. effectiveness, efficiency, and satisfaction of the user (AFNOR, 1998). The need to retrieve a particular image from a collection is shared by several user communities including teachers, artists, journalists, scientists, historians, filmmakers and librarians, all over the world. Image collections also have many areas of application: commercial, scientific, educational, and cultural. Until recently, image collections were difficult to access due to limitations in dissemination and duplication procedures. This research underlines the pressing necessity to optimize the methods used for image processing, in order to facilitate the imagesâ retrieval and their dissemination in multilingual environments. The results of this study will offer preliminary information to deepen our understanding of the influence of the vocabulary used in image indexing. In turn, these results can be used to enhance access to digital collections of visual material in multilingual environments.

A study of indexing in digitized news archives of Chinese newspapers in Taiwan

Yuan, Ming-Shu, Lin, Chih-Feng January 2006 (has links)
Many digital news archive systems in Taiwan are based on format description, not subject indexing. This requires users to know their background or the terminologies used, in order to retrieve information from these archives. This paper discusses how the original elements were indexed from various perspectives in Chinese digitized news archives. It also makes recommendations to improve the industry, including strengthening the process, connection, and description of news contents, organization, and management. This will enable cross-system retrieval and in-depth resource integration among systems.

Multilingual access to information using an intermediate language: Proefschrift voorgelegd tot het behalen van de graad van doctor in de Taal- en Letterkunde aan de Universiteit Antwerpen

Francu, Victoria January 2003 (has links)
While being theoretically so widely available, information can be restricted from a more general use by linguistic barriers. The linguistic aspects of the information languages and particularly the chances of an enhanced access to information by means of multilingual access facilities will make the substance of this thesis. The main problem of this research is thus to demonstrate that information retrieval can be improved by using multilingual thesaurus terms based on an intermediate or switching language to search with. Universal classification systems in general can play the role of switching languages for reasons dealt with in the forthcoming pages. The Universal Decimal Classification (UDC) in particular is the classification system used as example of a switching language for our objectives. The question may arise: why a universal classification system and not another thesaurus? Because the UDC like most of the classification systems uses symbols therefore, it is language independent and the problems of compatibility between such a thesaurus and different other thesauri in different languages are avoided. Another question may still arise? Why not then, assign running numbers to the descriptors in a thesaurus and make a switching language out of the resulting enumerative system? Because of some other characteristics of the UDC: hierarchical structure and terminological richness, consistency and control. One big problem to find an answer to is: can a thesaurus be made having as a basis a classification system in any and all its parts? To what extent this question can be given an affirmative answer? This depends much on the attributes of the universal classification system which can be favourably used to this purpose. Examples of different situations will be given and discussed upon beginning with those classes of UDC which are best fitted for building a thesaurus structure out of them (classes which are both hierarchical and faceted)...
