Link analysis is not applicable to all types of data nor can it solve all types of problems. The aggregate number of data records presented using link analysis is somewhat limited and the analyses tend to focus on verifying sets of related information. Different layouts, filter assessments, and presentation formats provide link analysis systems with the candid ability to quickly identify patterns that occur from unusual relationships, emerging groups, and important connections.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{265}'/><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>Some of the areas where link analysis has yielded good results are in analyzing telephone call patterns and combining leads of information sources.
