    Abstract
    An overview of the Internet is provided. It describes what the Internet is, how and when it was started, and the four main functions it currently offers. It then focuses on the World Wide Web, and in particular robots and search engines. An overview is provided of both robots and search engines, with some examples and illustrations. It concludes with how to choose a search engine for a particular enquiry, gives some hints and tips for Internet searches, and emphasises that good retrieval is achieved not only by good search engines but also by responsible Web mastering which helps to disseminate effectively any Internet published material.

    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
    Describes the concept of a proxy based information classification and filtering utility, named Web Assistant. On the behalf of users a private view of the WWW is generated based on a previously determined profile. This profile is created by monitoring the user anf group activities when browsing WWW pages. Additional features are integrated to allow for easy interoperability workgroups with similar project interests, maintain personal and common hotlists with automatic modification checks and a sophisticated search engine front-end

    Abstract
    Proposes an alternative way in assisting users in finding information on the WWW. Since the Web is made up many Web servers, instead of searching all the Web servers, proposes that ech server does its own housekeeping. A software agent named SiteHelper is designed to act as a housekeeper for the Web server and as a helper for a Web user to find relevant information at a particular site. In order to assist the Web user in finding relevant information at the local site, SiteHelper interactively and incrementally learns about the Web user's areas of interest and aids them accordingly. To provide such intelligent capabilities, SiteHelper deploys enhanced HCV with incremental learning facilities as its learning and inference engines

    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
    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
    Discusses problems of information overload and of devising a means to retrieve items of interest at a later date. Describes software agents and considers whether they are capable of development to the point where they could search the WWW and retrieve items rank ordered by personal interests. Suggests that although a good deal of research is being done with this end in view, there appears to be little as yet in the way of usable products, and nothing that meets this author's specific needs

    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
    Over the past few years the amount of information available on the WWW has grown so much and so fast that there is no accurate way to count or estimate it. Directory services and search tools do not learn about the searcher nor adapt themselves to his needs. Draws attention to a new generation of WWW sites that can be customized to the needs of users and offers examples of some of these personalized services

    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.
