Spatial personalization can be defined as a novel way to fulfill user information needs when accessing spatial information services either on the web or in mobile environments. The research presented in this paper introduces a conceptual approach that models the spatial information offered to a given user into a user-centered conceptual map, and spatial proximity and similarity measures that considers her/his location, interests and preferences. This approach is based on the concepts of similarity in the semantic domain, and proximity in the spatial domain, but taking into account user’s personal information. Accordingly, these spatial proximity and similarity measures could directly support derivation of personalization services and refinement of the way spatial information is accessible to the user in spatially related applications. These modeling approaches are illustrated by some experimental case studies.

The Web

Everyday hundreds of millions of users turn to the World-Wide Web as their primary source of information during their educational, business and personal lives. The Web is an essential source of businesscritical information but has also changed our personal lives, influencing the way that we learn, play, shop and socialise. During the course of a typical day an increasing number of us will interact with a variety of information services on the Web as we hunt for the information that we need. Very often these services will offer a number of alternative modes of information access and associated interfaces— navigation, search, and recommendation being the most common — each designed to help the user to efficiently fulfilling their current information needs. Navigation, search, and recommendation each have their own set of challenges when it comes to facilitating fast and efficient information access. In this chapter we will consider a number of these challenges and describe how they can be addressed by using techniques that allow information services to respond more intelligently to the needs and preferences of individuals and groups of users. Each challenge will be addressed in the form of a case-study focusing on one particular mode of information access (navigation, search, and recommendation) and an application scenario (mobile portals, Web search, and e-commerce), to describe how user profiling, personalization, and adaptive interface design can be combined to produce a more efficient and effective information service.

Problems associated with the improve ment of information retrieval for open environment are considered and the need for it’s semantization is grounded. Thecurrent state and prospects of development of semantic search engines that are focused on the Web information resources processing are analysed, the criteria for the classification of such systems are reviewed. In this analysis the significant attention is paid to the semantic search use of ontologies that contain knowledge about the subject area and the search users. The sources of ontological knowledge and methods of their processing for the improvement of the search procedures are considered. Examples of semantic search systems that use structured query languages (eg, SPARQL), lists of keywords and queries in natural language are proposed. Such criteria for the classification of semantic search engines like architecture, coupling, transparency, user context, modification requests, ontology structure, etc. are considered. Different ways of support of semantic and otology based modification of user queries that improve the completeness and accuracy of the search are analyzed. On base of analysis of the properties of existing semantic search engines in terms of these criteria, the areas for further improvement of these systems are selected: the development of metasearch systems, semantic modification of user requests, the determination of an user-acceptable transparency level of the search procedures, flexibility of domain knowledge management tools, increasing productivity and scalability. In addition, the development of means of semantic Web search needs in use of some external knowledge base which contains knowledge about the domain of user information needs, and in providing the users with the ability to independent selection of knowledge that is used in the search process. There is necessary to take into account the history of user interaction with the retrieval system and the search context for personalization of the query results and their ordering in accordance with the user information needs. All these aspects were taken into account in the design and implementation of semantic search engine "MAIPS" that is based on an ontological model of users and resources cooperation into the Web.

The Web

Purpose – The purpose of this article is to explore and conceptualize the Semantic Web as a term that has been widely mentioned in the literature of library and information science. More specifically, its aim is to shed light on the evolution of the Web and to highlight a previously proposed means of attempting to improve automated manipulation of Web-based data in the context of a rapidly expanding base of both users and digital content. Design/methodology/approach – The conceptual analysis presented in this paper adopts a three-dimensional model for the discussion of Semantic Web. The first dimension focuses on Semantic Web’s basic nature, purpose and history, as well as the current state and limitations of modern search systems and related software agents. The second dimension focuses on critical knowledge structures such as taxonomies, thesauri and ontologies which are understood as fundamental elements in the creation of a Semantic Web architecture. In the third dimension, an alternative conceptual model is proposed, one, which unlike more commonly prevalent Semantic Web models, offers a greater emphasis on describing the proposed structure from an interpretive viewpoint, rather than a technical one. This paper adopts an interpretive, historical and conceptual approach to the notion of the Semantic Web by reviewing the literature and by analyzing the developments associated with the Web over the past three decades. It proposes a simplified conceptual model for easy understanding. Findings – The paper provides a conceptual model of the Semantic Web that encompasses four key strata, namely, the body of human users, the body of software applications facilitating creation and consumption of documents, the body of documents themselves and a proposed layer that would improve automated manipulation of Web-based data by the software applications. Research limitations/implications – This paper will facilitate a better conceptual understanding of the Semantic Web, and thereby contribute, in a small way, to the larger body of discourse surrounding it. The conceptual model will provide a reference point for education and research purposes. Originality/value – This paper provides an original analysis of both conceptual and technical aspects of Semantic Web. The proposed conceptual model provides a new perspective on this subject.

Centres Of Excellence

The developing countries arc emulating the industrialized countries when setting up information services to cater for their information needs. However, the traditional infrastruc ture of service organisations may not be the best model for supporting easy and speedy access to information. A different approach is argued, founded upon the enthusiasm with which many developing countries have taken to online systems when demonstrated there. A model for a ministerial information network is proposed as part of a "social intel ligence function" of the country. It is proposed that Unesco and UNIDO should set up regional "centres of excellence" according to this model for developing countries.

Symbolic Boundary

This article examines ‘neighbouring’ as the setting in which cross-category relations develop and symbolic boundaries are constructed. The study is based on thirty in-depth interviews with residents living in a multi-ethnic and a mono-ethnic neighbourhood in Rotterdam, the Netherlands. The findings challenge the hoped-for outcomes of social mixing in neighbourhoods, as well as the view that boundary making is something inherent to multi-ethnic neighbourhoods only. Neighbour relations are often setting-specific (relations are interchangeable, scripted and bounded, and passively maintained), which is relevant for understanding the spatiality of neighbouring and the limited exchange of personal information between neighbours. Because neighbouring involves the balancing of personal privacy and close spatial proximity, the exchange of personal information is limited, while spatial proximity ensures easy access to observable (through seeing, hearing and smelling) categorical markers that signify class, ethnicity, lifestyle, etc. In this way, neighbour interaction reconstructs symbolic boundaries rather than breaking them down.

Purpose The purpose of this paper is to verify if the gender effects described in the wine consumer behaviour literature, namely, concerning information search and the motivations to buy, may be explained by the mediating effect of subjective knowledge, taking into consideration that the importance of knowledge in the decision process is gender specific. Design/methodology/approach A path analysis was modelled with an exogenous variable (gender), a mediating variable (subjective knowledge) and four dependent variables (need for information and three motivational dimensions). The model was assessed with empirical data obtained from a sample of 523 shoppers in large supermarkets in the areas of Lisbon and Oporto, Portugal. Structured interviews were conducted at checkout, collecting information on the relevant variables. Scales measuring the latent variables (knowledge, information and motivation) were previously validated through confirmatory factor analysis in a sample of 217 wine consumers. Findings Subjective knowledge fully mediates the effects of gender on motivation and information needs. Men think of themselves as more knowledgeable in wines and the mediation effect explains why, compared to women, they use less personal information sources and are more motivated to purchase wine. Practical implications The authors suggest promotion programmes in large supermarkets focussing on opportunities for wine knowledge development. Originality/value The study contributes to the literature by introducing and validating an alternative formulation of gender effects on wine shopping, emphasising the role of the purchaser’s perceived or subjective knowledge.
