Pattie Maes from the MIT Media Lab developed Firefly as an intelligent, active, and personalized agent collaborator. The idea behind collaborative filtering or agents is that instead of user-initiated interaction via commands of direct queries, the visitor is engaged in a cooperative process in which the software initiates communication, monitors events, and performs tasks. The concept of the original Firefly "agent" was that it would become gradually more effective as it learned a visitor's interests, habits, and preferences. Firefly was one of the first collaborative filtering firms, having started at the MIT Media Lab. It was subsequently purchased by Microsoft.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{8AF}'/><TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0><TR> <TD ROWSPAN=5></TD> <TD COLSPAN=3 HEIGHT=12></TD> <TD ROWSPAN=5></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR><TD></TD> <TD><FONT FACE='Times New Roman, Times, Serif' SIZE=3>In the core technology of Firefly, an agent memorizes which books, CDs, or other consumer items a visitor or customer has evaluated and purchased. Then it compares these preferences with other agents, correlating them with similar items and values—correlating them and assigning a value of "similarity" which it uses to recommend future books, CDs, etc. The important concept hidden in the application is that the agent gradually "learns" how to better assist the client, much like the corner store clerk who has observed your preferences. An agent learns by observing and imitating the customer, receiving feedback and instructions from the customer, and asking advice from other agents.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{8B0}'/><TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0><TR> <TD ROWSPAN=5></TD> <TD COLSPAN=3 HEIGHT=12></TD> <TD ROWSPAN=5></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR><TD></TD> <TD><FONT FACE='Times New Roman, Times, Serif' SIZE=3>Firefly's flagship product, called Firefly Passport, is used to collect user preferences anonymously, recommend Internet content, and send appropriate advertising. Passport, makes it possible for sites to register visitors and exchange user profiles with other Firefly-enabled sites. The company's one-time goal was to build a network of such sites and deliver personalized content and community services to registered users.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{8B1}'/><TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0><TR> <TD ROWSPAN=5></TD> <TD COLSPAN=3 HEIGHT=12></TD> <TD ROWSPAN=5></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR><TD></TD> <TD><FONT FACE='Times New Roman, Times, Serif' SIZE=3>The Firefly Navigator Catalog lets sites steer users toward products by creating personalized lists of recommendations and connecting users with similar interests.
