Since most chat sites require registration information about visitors, data can be gathered and used for targeting ads based on demographics, psychographics, gender, age, income, and of course the chat discussion topic. chats also tend to be topic-specific, which can provide a method for data gethering about visitor interests.</FONT></TD></TR></TABLE></TD></TR></TABLE><BR><A NAME='{45D}'/><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><B><I>Agents</I></B></FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{45E}'/><TABLE CELLPADDING=0 CELLSPACING=0 BORDER=0 WIDTH='100%'><TR><TD HEIGHT=12></TD></TR><TR><TD><TABLE CELLSPACING=0 BGCOLOR=#C0C0C0 BORDER=1 BORDERCOLOR=#000000 WIDTH=632 CELLPADDING=4><TR><TD WIDTH=632 VALIGN=TOP><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=2>Agents or " collaborative filtering" software programs make recommendations based on prior web activity by individuals with similar demographic or psychographic profiles. Affinity or collaborative programs are designed to make recommendations on the basis of what other people have liked with similar likes and dislikes to those of you. They make their recommendations based on your preference input and the activity of a community of users similar to you. the most prevalent of these collaborative filtering sites and software is FireFly, a pionner in using Al technology for commercial purposes. These types of collaborative filtering applications are usually deployed in websites selling music, videos, books, and other types of recreational products and services.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><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=2>Some agents act as filters, browsing through large amounts of data and providing their owners only the information that matches their criteria. Most intelligent agents are typically not website-specific. They instead involve the retrieval of the specific type of intelligence you furnish during the registration phase. there are several types of "agents". Some are server-specific while others are designed to cruise the Web in your behalf. For example, some agents are designed to roam the Web for specific information you are interested in. This can be keyword-specific or industry-or company name-driven , or take the form of information on a specific technology, news topic, product announcement, stock price or activity, company name, etc.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><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=2>The intelligence of these agents varies. Some are simply able to search on specific topics the owner specifies, and others, which are smarter, are able to look over your shoulder and cue on the specific keywords you typically search on, gradually "learning" what your interests are and through these observations suggest or search for information, products, or services in your behalf. Because agents require user registration and specific personal information and topics or keywords they represent yet another method of gathering important personal information for data mining.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE></TD></TR></TABLE></TD></TR></TABLE><BR><A NAME='{45F}'/></FORM></P></TD></TR></TABLE><P><FONT SIZE=0 COLOR=WHITE></CENTER><A NAME="bottom"> </A><!-- netLibrary.com Copyright Notice --> </BODY></HTML>⌨️ 快捷键说明
