(4) after the user was inquired about as follows and found the solution by data of design requirements (7), server produces first automatically formerly to be understood (9), second and formerly understands (11) or/and the 3rd formerly understand (13), and returns far-end computer through network and give the user:
1) user directly inquires about the inventive principle storehouse by data of design requirements, or/and the user imports the physical parameter inquiry inventive principle storehouse that produces contradiction; The user launches to check each knowledge entry of scientific effects storehouse through the functional tree classification, or/and directly inquire about the scientific effects storehouse through keyword search; Server produces the first former understanding thus;
2) user by the five kind modes of data of design requirements through the multi-layer network search software be from closely to loose search, be automatically converted to one or more keywords, and search for through the search engine of GOOGLE, Search Results is the second former understanding;
3) user assists innovation software by data of design requirements through on-line computer; At first get into case study: server asks a question from six aspects such as people, machine, material, environment, method, measurements automatically, helps the user from these six aspect problem analysis reasons; Pass through problem solving again: the user selects to import a problem reason, obtains the 3rd former understanding through the KBS search with the knowledge entry title;
(5) user is through the first former understanding directly inquiry in patent database, or/and the user inquires about in patent database through functional group; The user is through the knowledge entry of input first former understanding inquiry domain knowledge base, obtains the 4th and formerly understands (16);
(6) user imports evaluating, and server carries out evaluate alternatives automatically by judgement schematics.
2. make up and methods for using them by the said network platform of claim 1, it is characterized in that said step () 3) in the concrete grammar of five kinds of ways of search following:
1) Natural Language Search is to let the user directly import the idea of natural language expressing oneself, and system is through defining searching key word to natural language analysis; 2) the guiding search is to give expression to a plurality of keywords that need search through the system bootstrap user; 3) keyword search is to return Search Results through the coupling of single keyword; 4) classified browse is a system provides the reclassify catalogue of five classes, 58 one-level subjects, 573 secondary subjects, nearly 6000 three grades of subjects according to " People's Republic of China's subject classification and code national standard ", and the subject name through the third level is referred to as keyword; 5) random search is passed through extracting keywords Search Results on network in system database at random.
