Several below the approach of acquisition answer mainly contains on network now: as can to browse relevant professional website, can post in relevant forum and seek help, also can also put question to the searching answer by more existing knowledge polymerizing class website by various large-scale search engine searches correlated results based on search engine technique.
But existing these approach all have significant limitation and deficiency separately:
One, browse relevant professional website and require a great deal of time, can find the answer that oneself needs will depend on also whether web site contents is comprehensive, and for a lot of users and do not know that the problem of oneself need go to seek answer to which website.
Two, post to seek help in forum and need to wait for other user's answer, on problem resolution time, have uncertainty, limited to crowd's scope that problem is answered greatly and reduced the probability that finds answer thereby in forum, put question in addition.
Three, various large-scale search engines are in fact just searched for some key words in user's the enquirement, be not that problem is carried out real effectively the analysis and processing, therefore the result of search often comprises a large amount of invalid information, does not reach the effect that answer is just understood and answered.
Four, some knowledge polymerizing class websites based on search engine technique are exactly in fact the forum that has used search engine technique, so drawback of mentioning in two and three, it all exists equally, such as the timeliness of problem solution, such as can not effectively analyzing problem.For example, people wonders from Yuanmingyuan Park to the Forbidden City this how to get to, puing question to so may be following a variety of form: " how to get to Yuanmingyuan Park arrives the Forbidden City? " from Yuanmingyuan Park to the Forbidden City how by bus "? " " which Yuanmingyuan Park has to the mode of transportation of the Forbidden City? " or the like, perhaps, a certain enquirement form can search out answer, but changed a kind of enquirement form and perhaps just do not had answer, and quizmaster and do not know which kind of form of this usefulness puts question to, a same problem is expressed by different statements, can't effectively analyze and handle based on existing search engine technique.

" need participle to be " be Shaolin Temple good-looking? " the software module that the word segmentation processing of Chinese needs special-purpose participle software or oneself realizes, Peking University's computational language waits and has all developed corresponding software module).
The word segmentation processing sentence formula processing module that the back uses native system to carry that finishes is carried out a formula processing, determine the relevant factor of the sentence formula of user's question sentence and sentence such as SVO from etc.
Determine that formation can be sought the format problem of system handles by answer after the sentence formula, form by sentence formula, each key element of sentence, import as the user " Shaolin Temple is good-looking? " the format problem of handling back formation is (sentence a formula: yes-no question; Subject: Shaolin Temple; Judge main points: good-looking)
After forming the format problem, the key element that might produce ambiguity is carried out feedback processing, realize getting a real idea of user's original idea, form final format problem.As the Shaolin Temple in the example, after the ambiguity analysis, discovery exists (film) Shaolin Temple and (tourist attractions) Shaolin Temple, and the two all possesses and the characteristic of (judgement main points: good-looking) coupling, this just need feed back to the user, being confirmed by the user, is the film Shaolin Temple if the user asks, then finally forms format problem (sentence formula: yes-no question; Subject: film Shaolin Temple; Judge main points: good-looking).
Part is sought in answer:
The format problem that problem analysis system provides is handled, provided answer, answer can be the answer in the system answer storehouse, also can return the link of an external website to the user, and directly guides user is inquired about to the relevant speciality website of system recommendation.
(1) the format problem that problem analysis system is provided (being made of sentence formula, each key element of sentence) is carried out a formula analysis, determines the analysis and processing method of this formula correspondence
(2) use corresponding sentence formula analysis and processing method, from each key element of sentence, find out all keywords and their parameter separately
(3) according to the disposal route of each keyword, to each keyword and they with parameter handle
(4) gather whole keyword results, form preliminary answer
