Problems solved by technology

[0004] In the prior art, when obtaining relevant questions, the search words entered by the user are generally used as the core words to obtain them. This method is relatively simple and direct, but the correlation between the obtained relevant questions and the questions entered by the user is not very good. , often cannot meet the needs of users well, that is to say, the matching degree between the relevant questions obtained by it and the answers to the questions that users really want to obtain is relatively poor, resulting in poor accuracy of question retrieval on the Q&A page. The fit of user needs is relatively poor, and it cannot solve the search matching needs of users who want to view answers to questions that are closer to and more consistent with the searched questions on the current Q&A page

Embodiment 1

[0051] The question-and-answer page core word extraction method that embodiment one of the present invention provides, its flow process is as follows figure 1 shown, including the following steps:

[0052] Step S101: extracting core word candidate strings from the question-and-answer page.

[0053]When extracting the core words, the core word candidate strings used to determine the core words are extracted from the question-and-answer page, and the qualified core words are screened out from the candidate strings.

[0054] Extracting the core word candidate string from the question-and-answer page may extract the core word candidate string from the title of the question-and-answer page, or extract the core word candidate string from the page content of the question-and-answer page, or extract from the title of the question-and-answer page and the page content of the question-and-answer page.

Embodiment 2

[0064] The method for extracting core words on the question-and-answer page provided in Embodiment 2 of the present invention describes a specific implementation of core word extraction, and its flow is as follows figure 2 shown, including the following steps:

[0065] Step S201: Obtain a question-and-answer page corresponding to the search term input by the user.

[0066] For example: the user enters the search term "what should I do if my child has a cold and cough?", and the corresponding question-and-answer page is obtained according to the search term.
