The research on the software agents has already promote certain applications trying to facilitate the personal manipulation of the computer. This page will provide some applications as well as some sources in the field as to inspire the further understanding on the design, construction and development of those software agents. 

The application of the software agent falls into the following categories:

ˇ  Interface Agent

 

 

 

Operating system agents: agents executes locally in the  operation system and help user to interact with the operating system through its GUI shell.

IIntelligent Utility System Agent system agent for Windows 95, a background program that launches applications according to user-defined schedule, which is time based.

 Interface Agent: in charge of interacting with the user and of making transparent the other agents to him. (http://www.cilea.it/GARR-NIR/nir-it-95/atti/giannini/giannini/node4.html)

Open Sesame!  Open Sesame! is the software agent observes user events in their Macintosh applications, learns the repetitive user work patterns via a sequence clustering algorithm to find the best representative pattern for the given collection of sequences, and customize itself according to how the user works with it.

Letizia: is a user interface agent that assists a user browsing the World Wide Web. As the user operates a conventional Web browser such as Netscape, the agent tracks user behavior and attempts to anticipate items of interest by doing concurrent, autonomous exploration of links from the user's current position. The agent automates a browsing strategy consisting of a best-first search augmented by heuristics inferring user interest from browsing behavior.

Letizia: An Agent That Assists Web Browsing

Let's Browse: is an experiment in building an agent to assist a group of people in browsing, by suggesting new material likely to be of common interest. It is built as an extension to the Web browsing agent Letizia. Let's Browse features automatic detection of the presence of users, automated "channel surfing" browsing, and dynamic display of the user profiles and explanation of recommendations.

E-mail Agent: allows for the automatic forwarding, storage, and deletion of electronic mails, freeing the user from the necessity of coping with electronic junk mail. (Denning 1982)

Beyond Mail: a rule based agent for managing e-mail. The rule is When a specific event happens, if it meets certain conditions, then take the action. The difference between Beyond Mail and Open Sesame! Is user needs to define the messaging rules using a rule editor.

Meeting Scheduling Agent: acted as personal assistant who can negotiate a meeting in line with the preferences of its owners.

KautzBot and SelmanBot: developed at AT&T Bell Labs, communicated with other agents via email and attempted to automatically negotiate an acceptable meeting time for all involoved participatens.

An Experiment in the Design the Software Agent 

Web Search Agent:  traverse the Web hyperspace on behalf of users to provide services.

Web Compass, is a personalized parallel search query agent. The agent software comes with an initial source list of search engines that are modified by the user to reflect personal interests. 

Web Crawler 

DejaNews: Research Service for Usenet news.

City Net:  search services for geographic directories.

Harvest: a scalable architecture for indexing the Web based on a model that promotes cooperation.

Smartseach: an intelligent and efficient agent that carries out net-searches by simultaneously consulting the most important search engines of the Internet which are grouped under categories website.

BullsEye:  a search and retrieval agent that allows you to search multiple search engines (450+) through a single interface. BullEye integrates many of the tasks power searchers use under one intuitive interface and combines targeted meta-searching with full text analysis (via the Verity 97 toolkit), and filtering, for more relevant results. Works behind a firewall. Windows only. By Intelliseek.

Excite: Infoseek's desktop meta-search engine including pre-defined search categories but not filtering. User customizable and co-brandable. Anticipatory download of graphics. Windows only. By Infoseek.

Information Filtering Agents

NewsHound:  automatically searches articles and ads matching a user's profiles, and emails its findings. Users can adjust a Selectivity parameter to guide NewsHound to send more or fewer stories on a given topic. It is developed from San Jose Mercury News
