In　this　article　Web　mining　is　introduced　as　an　instrument　to　evaluate　technology　commercialization　potential.　Firstly,　we　discuss　Web　mining　approach　can　embrace　the　need　for　the　objective　evaluation　from　online　perspective:　uniform　resource　locator(URL)　analysis　can　get　indicative　information　about　the　stakeholders＇　origin;　link　analysis　via　Social　Netwok　Analysis(SNA)　allows　identification　of　stakeholders　online　and　can　divide　them　into　communities　according　to　their　relationship.　The　method　is　also　able　to　find　authoritative　Web　sites;　Web　content　analysis　allows　social　concern　and　sketchy　public　opinion　on　certain　evaluation　indicators　to　be　investigated.　Secondly,　a　feasible　framework　for　Web　mining　approach　is　proposed　step　by　step　with　some　available　software.　At　last,　the　development　direction　of　the　approach　and　further　wok　in　application　is　mentioned.　©　2008　IEEE.
