    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
    Intelligent agents should be used to assist users of the WWW. Identifies a number of key components in such a system and proposes a system architecture. Designs a learning agent along with the underlying algorithms for the discovery of areas of interest from user access logs. The discovered topics can be used to improve the efficiency of information retrieval by prefetching documents for the users and storing them in a document database in the system. Implements a prototype system

    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
    Presents a Guided tour system for the WWW, called Ariadne, which implements the ideas of trails and guided tours, originating from the hypertext field. Ariadne appears as a Java applet to the user and it stores guided tours in a database format separated from the WWW documents included in the tour. Itd main advantages are: an independent user interface which does not affect the layout of the documents being part of the tour, branching tours where the user may follow alternative routes, composition of existing tours into aggregate tours, overview map with indication of which parts of a tour have been visited an support for getting back on track. Ariadne is available as a research prototype, and it has been tested among a group of university students as well as casual users on the Internet

    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
    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
    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
    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

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
    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
    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
