We present a society of personal information agents that work for a community of users and that are aware of the physical and social context of their users. We show how context-awareness is a feature that allows the agents to improve their performance when they work with limited resources in information spaces with a large amount of information. The use of context information allows the agents to focus their information search and, as a result of this, increase the quantity and quality of information delivered to the user. Moreover, we propose an implemented agent architecture with context-aware capabilities. We discuss this architecture in detail, focusing on the capability of exploiting the windows of opportunity provided by the awareness of the users' activity. The agents use these windows of opportunity to furnish the user with information and advice in the situation where it can be most useful. In particular, we show how context-aware information agents can assist a community of attendees to big conferences and fairs. In this application, an information agent gathers relevant information based on a model of specific interests of a user. Given the multiplicity of interesting events, and their distribution in time and space, an information agent has to deliver the gathered information in a few hours and comply to the schedule constraints. Finally, we report some experimentation results to illustrate how context-awareness improve the service a society of information agents provides to a community of users in the conference application.

Awareness Context

This article discusses the interest of emerging a unified view for group awareness and context information on groupware and context-aware systems. Group awareness corresponds to an important concept on Groupware applications, allowing individual users to be kept aware of group's activities and status. Context is defined by ubiquitous computing as any relevant information that can be used to characterize the situation of an entity. We assume that group awareness information should be considered as context information and handled as such. Group awareness information is often employed for decision making, contributing to users' activities and decisions, but it gives also an important clue about user's context, characterizing individual's actions regarding the group. As such, group awareness may be used for adaptation purposes, adapting the system behavior, the supplied content or its services. Besides, architectural concerns adopted on context-aware system should also be considered when developing new groupware applications that are more and more designed as context-aware systems.

Intelligent Information

Personal information agents have emerged in the last decade to help users to cope with the increasing amount of information available on the Internet. These agents are intelligent assistants that perform several information-related tasks such as finding, filtering and monitoring relevant information on behalf of users or communities of users. In order to provide personalized assistance, personal agents rely on representations of user information interests and preferences contained in user profiles. In this paper, we present a summary of the state-of-the-art in user profiling in the context of intelligent information agents. Existing approaches and lines of research in the main dimensions of user profiling, such as acquisition, learning, adaptation and evaluation, are discussed.

In this study searched for the survey paper on recommendation system. Recommendation system sorts through massive amounts of data to identify interest of users and makes the information search easier. For that purpose many methods have been used. Collaborative Filtering (CF) is a method of making automatic predictions about the interests of customers by collecting information from number of other customers, for that purpose many collaborative base algorithms are used. Web Recommendation(WR) help the website visitors for easy navigation of web pages, quickly reaching their destination and to obtain relevant information. Content based filtering method(CBF) filtering is done based on customer’s interested items. In content-based filtering technique, the web pages are recommended for a user very quickly from ancient database. In that database different content of items are added that the user has used in the ancient times and/or user’s personal information and preferences.

AbstractIn the Big Data era, every sector has adapted to technological development to service the vast amount of information available. In this way, each field has benefited from technological improvements over the years. The cultural and artistic field was no exception, and several studies contributed to the aim of the interaction between human beings and artistic-cultural heritage. In this scenario, systems able to analyze the current situation and recommend the right services play a crucial role. In particular, in the Recommender Systems field, Context-Awareness helps to improve the recommendations provided. This article aims to present a general overview of the introduction of Context analysis techniques in Recommender Systems and discuss some challenging applications to the Cultural Heritage field.

AbstractContext awareness is essential for successful business process management (BPM). So far, research has covered relevant BPM context factors and context-aware process design, but little is known about how to assess and select BPM methods in a context-aware manner. As BPM methods are involved in all stages of the BPM lifecycle, it is key to apply appropriate methods to efficiently use organizational resources. Following the design science paradigm, the study at hand addresses this gap by developing and evaluating the Context-Aware BPM Method Assessment and Selection (CAMAS) Method. This method assists method engineers in assessing in which contexts their BPM methods can be applied and method users in selecting appropriate BPM methods for given contexts. The findings of this study call for more context awareness in BPM method design and for a stronger focus on explorative BPM. They also provide insights into the status quo of existing BPM methods.

The Right

Abstract The need of private insurers for information on the candidate’s health risks is recognized by the law, which places pre-contractual duties of disclosure upon the candidates. When the risks are influenced by health factors, e.g. in the case of life- and health insurances, it implies the provision of health information by the candidates, who thus voluntarily limit their right to privacy. This consent, however, often happens in a context of factual coercion to contract. Next to this, from a legal standpoint, the collection of personal information must respond to the principle of proportionality. Against this background, this article assesses the compatibility of questionnaire techniques that rely on open-ended health related questions with the right to privacy, as protected by Portuguese and international law. It then analyses the extent of pre-contractual duties of disclosure as defined by the Portuguese Insurance Act, which requires the candidate to volunteer all the relevant information independently of being asked for it. In doing so, the article also refers to some other European countries. It concludes that the relevant Portuguese legislation is incompatible both with Portuguese constitutional law and with international law.

Paradoxical Situation

In this paper I analytically review the literature on the information overload problem, with special reference to the business organizations and entrepreneurship and the study mainly reveals that the problem of the information overload has been existed for many years, whereas in current years the problem has become more clearly recognized and experienced. A concern stressed in the literature is the paradoxical situation that most probably there is an abundance of information available and it is often difficult to obtain useful, and relevant information when it may be needed. Both perceptions and the actual effects of information overload have exacerbated by rapid advances made in the information and communication technology, whereas it is not clear cut as to whether Internet has worsened/improved the situation. Some solutions have put forward to reduce the information overload are a reduction in duplication of the information found in professional literature; the adoption of the personal information management strategies, along with the integration of software solutions such as push technology and intelligent agents; and the provision of value-added information. Main emphasis is placed on the technology as a tool and not driver, while increased in information literacy may provide key to reducing the information overload in organisations.

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.
