5Rorissa, A. ; Iyer, H.: Theories of cognition and image categorization : what category labels reveal about basic level theory.
In: Journal of the American Society for Information Science and Technology. 59(2008) no.9, S.1383-1392.
Abstract: Information search and retrieval interactions usually involve information content in the form of document collections, information retrieval systems and interfaces, and the user. To fully understand information search and retrieval interactions between users' cognitive space and the information space, researchers need to turn to cognitive models and theories. In this article, the authors use one of these theories, the basic level theory. Use of the basic level theory to understand human categorization is both appropriate and essential to user-centered design of taxonomies, ontologies, browsing interfaces, and other indexing tools and systems. Analyses of data from two studies involving free sorting by 105 participants of 100 images were conducted. The types of categories formed and category labels were examined. Results of the analyses indicate that image category labels generally belong to superordinate to the basic level, and are generic and interpretive. Implications for research on theories of cognition and categorization, and design of image indexing, retrieval and browsing systems are discussed.

Abstract: 1. Introduction In this age of world wide communication, and the resulting thrust towards universality, the domain specific specialized vocabularies used in the visual resources and bibliographic databases pose limitations of access. Although they provide adequate access to the experts in the field, a layperson with little or no knowledge in the field (lay user) is constrained by the terminology. The meaning of the index terms used in the databases or the choice of search terms is not easy for such a user. It presupposes the ability of the users to demarcate and discriminate a concept/entity from other entities, and a lay user is often unclear about the connotations of the terms, and the subtle differences in their usage within the domain. The challenge to any indexer of visual resources is the subjective nature of the interpretation of the image itself. Images very seldom contain any textual information besides title, creator or date. However, images also need to be accessed for content and context as well, and context and content description are very often left to "the eye of the beholder." Utilizing standardized terminology can help classify and define an image more accurately, thereby improving accessibility. However, the special needs of a lay user still remain to be addressed. The use of as an auxiliary resource may help alleviate this problem to some extent. This paper presents the findings of an exploratory study to assess the value of WordNet as a pre-search tool to aid in the understanding and the identification of concepts, including the terminology needed to search visual resources databases in the field of architecture. It also reveals the nature of the problems encountered by lay users and how specific aspects of WordNet were helpful. WordNet is an electronic lexical database based an psycho-linguistic theories of human lexical memory, developed and maintained at Princeton University since 1985. Sets of synonymous terms (or synsets) constitute its basic organization. English nouns, verbs, an adjectives are organized into synsets, each representing one underlying lexical concept. Several types of relationships between the synsets are recorded in Wordnet.

Abstract: Converging digital technologies and networks, especially the Internet offer considerable scope for individuals and organizations to be authors and publishers with the possibility of getting global response to one's ideas. But there are also several impediments to overcome - existence of a multiplicity of languages, cultural bias, misinterpretation of concepts, non-existence and/or non-acceptance of ideas of one group by people of other cultures and faiths. This paper examines the types of indexes, glossary of terms, organization and presentation of text in different languages/scripts, transliteration of selected text, commentaries, help to correct pronunciation, listing of common errors in rendering text, song, etc. by beginners and people of different cultures and language groups, etc. as means and approaches to mitigate the difficulties of communication across cultures, faiths, and linguistic boundaries. Such provision in typical examples of information resources in the spiritual field - an Internet site, and two CD multimedia - is discussed.

In: Cataloging and classification quarterly. 37(2003) nos.1/2, S.115-130.
Abstract: Enumerates various paths that may lead to knowledge discovery (KD). Most of these paths begin from knowing what exists. To know what exists about an entity requires comprehensively assembling relevant data and information, in-depth analysis of the information, and identifying relations among the concepts in the related and even apparently unrelated subjects. Provision has to be made to reorganize and synthesize the information retrieved and/or that obtained through observation, experiment, survey, etc. Information and communication technologies (ICT) have considerably augmented the capabilities of information systems. Such ICT applications may range from the simple to sophisticated computerized systems, with data gathered using aerial photography, remote sensing, satellite imagery, large radar and planetary telescopes and many other instrument records of phenomena, as well as downloading via the Internet. While classification helps in data prospecting and data mining, for it to assist the KD process effectively it has to be supplemented with good indexes, hypertext links, access to statistical and modeling techniques, etc. Computer software assists text analysis, complex data manipulation, computation, statistical analysis, concept mapping, etc. But manual information systems can also assist KD. Enumerates several prerequisites to KD and relevant tools and techniques to be incorporated into information support systems. Presents case studies of information systems and services that assisted KD.

9Iyer, H. ; Giguere, M.: Towards designing an expert system to map mathematics classificatory structures.
In: Knowledge organization. 22(1995) nos.3/4, S.141-147.
Abstract: The convertibility of ordering systems such as thesauri and classification schemes have been investigated for many years. The focus has so far been more on thesauri than on classification schemes. Classification schemes too could differ from one another in several ways: in their structural, semantic, lexical and notational features. These incompatibilities make multiple catalog search difficult for the users. The DDC is one of the widely used schemes worldwide that encompasses all of knowledge whereas the Mathematics Subject Classification schem published by the American Mathematical Society is a special classification scheme that is used in several AMS publications, notably the Mathematical Review. An interface that enables mathematicians to access library collections organized with the DDC, using the AMS scheme as an interface will certainly by useful. This paper suggests a prototype expert system interface to map the MSC scheme on to the mathematics (510 schedule of DDC20) and presents the work done so far towards this end. Compares the 2 schemes and discusses the mapping strategies/rules developed and the features of the prototype expert system design

11Iyer, H.: Semantic interpretation of conjuncts : Boolean transformations.
In: International classification. 19(1992) no.1, S.72-76.
Abstract: Reports on an exploratory study of the semantic interpretation of conjuncts and their translation into Boolean search statements, using dictionary definitions. Rules were formulated based on syntactic and semantic analysis of the conjunctive phrases occuring in 160 natural language statements (NLS) of users information needs. This includes a set of transformational rules to accomodate variations in natural language expressions. Evaluation of the rules to accomodate variations in natural language expressions. Evaluation of the rules was performed by matching the output of the algorithm with the search formulation done by an expert online searcher. It resulted in an 81% match rate

15Iyer, H.: Facet-structure of subjects : an empirical study of concreteness and predictibility of categories.
In: Library science with a slant to documentation. 19(1982), S.223-239.
Abstract: Facet analysis of subjects is found helpful for information storage and retrieval in libraries and information systems. However, such an analysis introduces chances for alternative interpretations of combinations of facets in a subject proposition. This variance in interpretation may be measured in relation to concreteness of the categories. The postulate of PMEST is empirically verified from this point of view. Further, a correlation between concreteness of category and its predictibility is established on the basis of information theory. It is found that PMEST structure of subject-proposition reflects the direct correlation of concreteness and predictibility
16Raghavan, K.S. ; Iyer, H.: Structuring of compound and complex subjects in social sciences : a user's survey.
In: International classification. 5(1978) no.1, S.8-14.
Abstract: Based on a paper presentend to the Documentation Research and Training Centre 'Seminar on classification and indexing in social sciences', Bangalore. An analysis of a detailed survey on facet-analysed subject strings in the field of social sciences. Subject strings of 4 typers were administered as a stratified sample of responses to identify the gaps in semantic connotation of terms. This survey has helped to idetify the possible aberrations in the semantic connotations due to the presence or absence of terms. It was found that use of prepositions, conjunctions and other role indicating terms gives semantic clarity. The syntax of speciator terms may have to be varied according to the respondent groups. It was found that if the number of component terms in a subject string increases beyond a certain limit it gives rise to problems in interpretation of ideas. This indicates a break-even point for formulating subject headings

Abstract: In large collections of images, one of the ways to facilitate browsing is by providing thumbnails of representative images. This paper seeks to examine the issue of choice of representative images within the categories. Towards this end, a study of free sorting of 50 images by 75 participants was conducted, in which they sorted the images into categories and selected a representative image for the categories and also indicated the prominent feature in the selected image. The results indicate that there is reasonable agreement in the choice of representative images and the selection of prominent features appearing in the images. The prominent feature seems to be one of the factors that have a bearing on the way people categorize.
