    Abstract
    In building intelligent network agents, computer scientists may employ a variety of different design strategies, and their design decisions can have a significant effect on the ultimative nature of network interactions. Focuses on a particular design question, the multiple-access problem: if an agent seeking a piece of information knows of several sites that have, or might have, that information, how many queries should it issue, and when? Provides a formal analysis that demonstrates the viability of cooperative responses th this question under certain assumptions. discusses the limitations of this analysis and presents the results of experiments done using a genetic-algorithms approach in which simulated network agents 'evolve' cooperative strategies under less restrictive assumptions tham those made in the formal analysis

    Abstract
    Reviews 3 WWW programmes that help deal with information overload. Farcast is a personalized new service in which all commands are delivered and information retrieval via email. It uses droids or electronic agents to search the full text of newsfeeds and send summaries. Quarterdeck's WebCompass is a search manager that employs multiple resources to search the Internet for relevant material based on user-defined queires. It generates summaries based on the most significant sentences in the entire document. Search results are displayed on a multi-pane interface. ForeFront Group's Web-Whacker automatically searches user-defined Web sites, organises them into categories and downloads them into a database that resides on the user's computer. The sites can then be browsed off-line

    Abstract
    Presents an overview of intelligent software agents in information retrieval, including an explanation of agents and agent architecture, and presents several agent systems. Distinguishes between agents as individual entities, whose properties and characteristics are described separately, and agent systems as collections of agents utilised for information retrieval tasks, which are discussed in terms of individual implementations

    Abstract
    Over the last few years the use of the agent/multi-agent paradigm has grown sharply. This paradigm has been applied to different fields including control processes, mobile robots, and information retrieval. In this paper, we present a system architecture based on the agent and multi-agent paradigm that allows us to retrieve and manage any kind of information from the Internet. We present our architecture as a generic and open system architecture. One of its main features is the agents' independence from the network's dynamic. We explain in detail what has already been done in our architecture as well as our future plans

    Abstract
    Considers the possible future role of intelligent agents as filters for the flow of unstructured information and as a means of providing users with personalized information services which could act as a substitute for function currently performed in society by newspapers. Concludes that many of the arguments, used to support the idea that the drive to create intelligent agents are user driven, are flawed and that the drive is market driven

    Abstract
    The InfoFinder agent learnes profiles of user interests from sample documents submitted by the user while browsing, without requiring the user to complete a questionnaire about interests in various documents. It learns general profiles from the documents by heuristically extracting phrases from the documents taht are likely to represent the topic of the document. Its learning algorithm generates a search tree, which is then translated into a Boolean search string for submission to a generic search engine. It sends the user regular updates on documents without requiring the user to take the initiative to access the agent

    Abstract
    A novel idea of media agent is briefly presented, which can automatically build a personalized semantic index of Web media objects for each particular user. Because the Web is a rich source of multimedia data and the text content on the Web pages is usually semantically related to those media objects on the same pages, the media agent can automatically collect the URLs and related text, and then build the index of the multimedia data, on behalf of the user whenever and wherever she accesses these multimedia data or their container Web pages. Moreover, the media agent can also use an off-line crawler to build the index for those multimedia objects that are relevant to the user's favorites but have not accessed by the user yet. When the user wants to find these multimedia data once again, the semantic index facilitates text-based search for her.

    Abstract
    Reviews the Autonomy intelligent search agent for the Internet. The system searches for Internet sites based on a description of the search problem, the user selects suitable documents and the search is retained using this selection. The evaluation indicates that Autonomy is not suited to ad hac one-off searches as it takes too long compared to more traditional search engines. Search agents could be used for monitoring the WWW, or searching newspapers

    Abstract
    Evaluates a range of commercially available software designed to act as intelligent search agents to assist users find materials of interest on the Internet and WWW or selects for them without asking. Notes that existing search engines can be useful in finding information but their different features and sometimes unfriendly interfaces can be confusing and intelligent search agents may be able to overcome these difficulties. Singles out one package: Autonomy; from Autonomy Corporation, describes its specific features and reports results of a test conducted with the software. Concludes that, from the test results, Autonomy is not yet ready to challenge the existing Internet search engines, which in the tests performed better than Autonomy with regard to recall and precision of information retrieval. Autonomy did not give enough feedback to control the search action

    Abstract
    As part of the ongoing Illinois Digital Library Initiative project, this research proposes an intelligent agent approach to Web searching. In this experiment, we developed 2 Web personal spiders based on best first search and genetic algorithm techniques, respectively. These personal spiders can dynamically take a user's selected starting homepages and search for the most closely related homepages in the Web, based on the links and keyword indexing. A graphical, dynamic, Jav-based interface was developed and is available for Web access. A system architecture for implementing such an agent-spider is presented, followed by deteiled discussions of benchmark testing and user evaluation results. In benchmark testing, although the genetic algorithm spider did not outperform the best first search spider, we found both results to be comparable and complementary. In user evaluation, the genetic algorithm spider obtained significantly higher recall value than that of the best first search spider. However, their precision values were not statistically different. The mutation process introduced in genetic algorithms allows users to find other potential relevant homepages that cannot be explored via a conventional local search process. In addition, we found the Java-based interface to be a necessary component for design of a truly interactive and dynamic Web agent

    Abstract
    Presents the Selection Recognition Agent (SRA), an application for Windows-based personal computers. It recognises meaningful words and phrases in highlighted text and enables useful operations on them. The SRA includes 7 recognition modules, for geographic names, dates, electronic mail addresses, and phone numbers, Usenet newsgroup name components, Microsoft Outlook 97 contact records, and URLs, as well as a module that enables useful operations on text in general. Describes the architecture and design of the SRA. The experiments demonstrate that the SRA significantly reduces the time and effort users must expend in performing common tasks
