Abstract

Purpose A higher level of retrieval relevance along with pertinence is what information systems are required to provide if they are to gain more user satisfaction. Although in almost every IR system, general and non-topical terms are not considered to play a major role in indexing, the underlying assumption of current study stems from the fact that these terms could be effective in better searching by end-users. Thus this paper aims at proposing a new approach in this regard using a small thesaurus of general and non-topical terms which can be used along with queries (i.e., topical keywords). This would help making users' queries closer to natural language. Method In the first phase of this study, a set of 669 non-topical terms, which were identified through a previous study, was assumed as the test bed. Based on the main goal of the present paper, the list was analyzed and divided into major categories. As for the second phase, a preferred label representing each category was selected and assigned based on its "use warrant"; and to this end Google Trends was applied for determining the most-frequent general and non-topical terms among users' web searches. At last the developed thesaurus was tested in searching and the retrieved results were evaluated in terms of relevance and pertinence. Results The findings of this study show that, although there is rather a diverse range of general and non-topical terms appearing before or after topical keywords in Web documents, users are still using no or only a small fracture of them in their search queries. The findings also show that these terms would be of great assistance in providing more relevant results and a meaningful display of the results. This paper then proposes a conceptual model for applying such a thesaurus in searching the Web.

Abstract

The general purpose of this study is to assess the amount of catalogers' familiarity with Resource Description and Access (RDA) and their readiness for acceptance of these rules and the effect of training on this issue. The methodology of the presented research is a survey study using a descriptive-analytic approach. In this research, the familiarity of 49 catalogers, working for the Cataloging In Publication (CIP) department at the National Library and Archive of Iran with RDA was monitored before and after a training session through a questionnaire. It was specifically prepared for measuring catalogers' familiarity with, and acceptance of, RDA and also highlighting the self-identified and actual levels of this familiarity and acceptance. The results show that before training, catalogers' self-identified familiarity with RDA was higher than the average level. But after the training session, both self-identified and actual familiarity raised dramatically. Furthermore, the significant difference between the research population's features and self-identified, actual familiarity and the rules' acceptance rate among catalogers was examined. In this study, it was confirmed that there is a significant difference between self-stated and actual familiarity of catalogers regarding RDA. According to the results, M.A. catalogers have a self-identified familiarity higher than B.A. catalogers. It was also confirmed that the actual familiarity of catalogers with an M.A. degree before training is higher than catalogers holding a B.A.

Abstract

The goal of this research is investigating the situation of existing bibliographic records in the online public access catalog of the National Library of Iran in order to use Resource Description and Access (RDA). A sample of 111 bibliographic records was selected for this purpose. These records were analyzed according to the RDA codes. The results reveal that more than 88% of the records show a rather good conformity with RDA, but 47% of the remaining problematic records show direct inconformity with RDA. Based on an in-depth analysis of the fields, most of the discrepancies deal with the assumed rules based on which the data is entered. The results of this study indicate that there is a good level of conformity between contents of current records and RDA, but as for the rest of the records there are some major tasks to be done.

Abstract

It is widely accepted that subject indexing of an image is based on a two-dimensional approach. The first is the ofness and the second focuses on aboutness of the image. Assigning a suitable set of subject tags based on these two groups depends, to a great deal, on users' perception of the image. This study aims at analyzing users' perception of aboutness and ofness of images. 25 in-depth semi-structured interviews were conducted in two phases. In the first phase a collection of 10 widely known photographs were given to the interviewees and they were asked to assign subject tags (as many as they wanted) to each image. In the second phase some facts regarding each image were given to him / her to assign further tags (again as many as they wanted) or even modify their previous tags. The results show that the interviewees do focus both on ofness and aboutness in subject tagging; but it seems that they emphasize more on aboutness in describing images. On the other hand, as soon as the interviewees were able to distinguish the iconographical ofness, they could speak of iconographical and iconological aboutness. The results also show that subject indexers must focus on the iconographical level, especially regarding those tags which represent the ofness at this level.
