Today,　under　the　conditions　of　the　increasingly　intense　competition　on　the　market,　in　order　to　avoid　unnecessary　investment　and　gain　the　seeds　for　technology　development,　enterprises　not　only　need　to　know　the　current　state　of　technology　products,　but　also　need　to　grasp　its　future　development.　Therefore,　the　accurate　and　reliable　analysis　of　technology　development　trend　has　become　increasingly　important　practical　significance.　However,　current　methods　for　technology　development　trend　analysis　have　some　drawbacks.　Therefore,　we　propose　analysis　of　technology　development　trend　by　using　Web　mining,　and　try　to　make　some　new　studies　in　this　field.
