- Abstract
- In this paper, we present a system called IICA (Intelligent Information Collector and Analyzer) which gathers, classifies, and reorganizes information from the Internet. Ontology plays an important role in IICA. It specifies the common background knowledge shared by the user and IICA, allows IICA to make inexact match between the user's request and the candidates, and assigns user-oriented categories. IICA extracts information using a state transition network grammar and concept frames. We have implemented and evaluated IICA. The results shows the feasibility and robustness of the approach

- Abstract
- Although researchers have theorized the critical importance of classification in the organization of information, the classification approach seems to have given way to the alphabetical subject approach in retrieval tools widely used in libraries, and research an how users utilize classification or classification-like arrangements in information seeking has been scant. To better understand whether searchers consider classificatory structures a viable alternative to information retrieval, this article reports an a study of how 24 library and information science students used Yahoo! directories, a popular search service resembling classification, in completing an assigned simple task. Several issues emerged from the students' reporting of their search process and a comparison between hierarchical navigation and keyword searching: citation order of facets, precision vs. recall, and other factors influencing searchers' successes and preferences. The latter included search expertise, knowledge of the discipline, and time required to complete the search. Without a definitive conclusion, we suggest a number of directoons for further research.

- Abstract
- This study analyzes the models of representation and organization of knowledge surrounding Gender. In addition to assessing their visibility, we analyze the thematic models and the conceptual treatment of Gender in search engine directories with wide coverage in different parts of the world. Eight seach engines were selected, two of them international (Yahoo, Google), one an international affiliate (Yahoo España), and five local ones (three from the Mercosur, and one apiece from Africa and Asia). The research was done an two levels: a) knowledge representation through the quantitative and qualitative analysis of the terms of Gender; b) knowledge organization, through the structural and semantic-conceptual analysis of the search engines. The results express a clear terminological and structural supremacy of the international search engines, as well a lack of correspondence overall among the terminologies, relative visibility, and diffusion of matters of Gender, leading to considerable difficulties in achieving consistent access to specific information.

- Abstract
- User interfaces of Web search engines reflect attributes of the underlying tools used to create them, rather than what we know about how people look for information. In this article, the author examines several characteristics of user search behavior: the variety of information-seeking goals, the cultural and situational context of search, and the iterative nature of the search task. An analysis of these characteristics suggests ways that interfaces can be redesigned to make searching more effective for users.

- Abstract
- Presents a novel method to extract from a web object its hyper informative content, in contrast with current search engines, which only deal with the textual information content. This method is not only valuable per se, but it is shown to be able to considerably increase the precision of current search engines. It integrates with existing search engine technology since it can be implemented on top of every search engine, acting as a post-processor, thus automatically transforming a search engine into its corresponding hyper version. Shows how the hyper information can be usefully employed to face the search engines persuasion problem

- Abstract
- Users who want to exploit all the information sources on the Web will need an efficient search and selection tool e.g. a directory or search engine. Directories list Web sites and analyze their contents. Describes the behind-the-scenes work of documentalists specialized in surfing, tracking and indexing French language sites for the directory Nomade. Describes the creation of Nomade, its functioning and indexing, and how this new profession of 'cyber-documentalist' is changing the practices and functions of information professionals as they become Internet information organizers

- Abstract
- Web search engines, such as Google and Bing, are constantly employing results from knowledge organization and various visualization features to improve their search services. Knowledge graph, a large repository of structured knowledge represented by formal languages such as RDF (Resource Description Framework), is used to support entity search feature of Google and Bing (Demartini, 2016). When a user searchs for an entity, such as a person, an organization, or a place in Google or Bing, it is likely that a knowledge cardwill be presented on the right side bar of the search engine result pages (SERPs). For example, when a user searches the entity Benedict Cumberbatch on Google, the knowledge card will show the basic structured information about this person, including his date of birth, height, spouse, parents, and his movies, etc. The knowledge card, which is used to present the result of entity search, is generated from knowledge graphs. Therefore, the quality of knowledge graphs is essential to the performance of entity search. However, studies on the quality of knowledge graphs from the angle of entity coverage are scant in the literature. This study aims to investigate the coverage of entities of knowledge graphs behind Google and Bing.

- Abstract
- The explosion of the information available on the Internet has made traditional information retrieval systems, characterized by one size fits all approaches, less effective. Indeed, users are overwhelmed by the information delivered by such systems in response to their queries, particularly when the latter are ambiguous. In order to tackle this problem, the state-of-the-art reveals that there is a growing interest towards contextual information retrieval (CIR) which relies on various sources of evidence issued from the user's search background and environment, in order to improve the retrieval accuracy. This chapter focuses on mobile context, highlights challenges they present for IR, and gives an overview of CIR approaches applied in this environment. Then, the authors present an approach to personalize search results for mobile users by exploiting both cognitive and spatio-temporal contexts. The experimental evaluation undertaken in front of Yahoo search shows that the approach improves the quality of top search result lists and enhances search result precision.

- Abstract
- Reports on research into the information-seeking habits of primary schoolchildren conducted under operational conditions. Three workstations with Internet access were installed in a grade-six classroom in suburban Montreal. After a short introductory training session for the entire group followed by short individual sessions for each student, 53 students, working in small groups, used these workstations over a six-week period to seek information on the Web of relevance to a class project assigned by their teacher. The project dealt with the Winter Olympic Games (recently completed at that time). The student objective was to locate relevant information for a poster and an oral presentation on one of the sports represented at the Games. All screen activity was directly captured on videotape and group conversations at the workstation were audiotaped. Demographic and computer literacy information was gathered in a questionnaire. This paper presents a map of the information-seeking landscape based upon an analysis of the descriptive statistics gathered from the Web searches. It reveals that the novice users favored browsing over analytic search strategies, although they did show some sophistication in the construction of the latter. Online help was ignored. The children demonstrated a very high level of interactivity with the interface at the expense of thinking, planning and evaluating. This is a preliminary analysis of data which will subsequently be expanded by the inclusion of qualitative data
