In　this　talk,　we　give　a　new　perspective　of　Web　Intelligence　(WI)　research　from　the　viewpoint　of　Brain　Informatics　(BI),　a　new　interdisciplinary　field　that　studies　the　mechanisms　of　human　information　processing　from　both　the　macro　and　micro　viewpoint　by　combining　experimental　cognitive　neuroscience　with　advanced　information　technology.　As　two　related　emerging　fields　of　research,　WI　and　BI　mutually　support　each　other.　When　WI　meets　BI,　it　is　possible　to　have　a　unified　and　holistic　framework　for　the　study　of　machine　intelligence,　human　intelligence,　and　social　intelligence.　We　argue　that　new　instruments　like　fMRI　and　information　technology　will　revolutionize　both　Web　intelligence　and　brain　sciences.　This　revolution　will　be　bi-directional:　new　understanding　of　human　intelligence　through　brain　sciences　will　yield　a　new　generation　of　Web　intelligence　research　and　development,　and　Web　intelligence　portal　techniques　will　provide　a　powerful　new　platform　for　brain　sciences.　The　synergy　between　these　two　fields　will　advance　our　understanding　knowledge,　intelligence,　and　creativity.　As　a　result,　Web　intelligence　will　become　a　central　topic　that　will　change　the　nature　of　information　technology,　in　general,　and　artificial　intelligence,　in　particular,　towards　human-level　Web　intelligence.　©　Springer-Verlag　Berlin　Heidelberg　2006.
