    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
    Describes the Internet Fish Construction Kit, a tool for building persistent, personal, dynamic information gatherers for the WWW. Internet Fish (IFISH) differ from current resource discovery tools in that they are introspective, incorprating deep structural knowledge of the organization and services of the Web, and are also capable of on-the-fly reconfiguration, modification and expansion. Introspection lets IFISH examine and automatically remember not only what information has been uncovered but also how that information was derived

    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
    The growing complexity of sources of information and users' needs for information is fast outstripping the manual browsing and searching interfaces of the past. A long-term approach to the complexity problem is to design intelligent information agents that provide active assistance in the process of finding and organizing information. These agents differ from conventional information retrieval in how they interact with the user and the dynamic nature of the information they deal with. This article surveys some work at the MIT Media Lab in developing intelligent informations, especially as assistants to users browsing the Web. These agents don't replace conventional browsing or direct manipulation interfaces, but work with such interfaces to learn from interaction with the user, anticipate the user's needs, and connect the user with othe people who may share his or her interests

    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
    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
