Problems solved by technology

[0003] However, after users ask questions on the knowledge question answering system, they need to wait for other users to answer the questions before they can obtain the knowledge information they need. This will cause users to be unable to provide relevant knowledge quickly and accurately when they have urgent questions that need to be answered urgently. information

Embodiment 1

[0089] figure 1 It is a flow chart of the method for acquiring relevant knowledge information provided by Embodiment 1 of the present invention, as shown in figure 1 As shown, the method may include the following steps:

[0090] Step 101: Analyze the search log to dig out hot queries with doubtful requirements.

[0091] The search logs can be analyzed periodically, and the search logs in the current period can be captured; then, the search logs in the current period captured can be used to mine hot queries with doubtful requirements. Among them, the cycle of analyzing the search log can be flexibly set, for example, the cycle is taken every day, and hot queries with doubtful requirements are mined from the search log of the current day.

[0092] This step is actually divided into two parts: one part is to identify whether the query in the search log has doubtful requirements; the other part is to determine the hot query. The operations of these two parts can be executed in ...

Embodiment 2

[0115] figure 2 The flowchart for determining the hotspot query provided by Embodiment 2 of the present invention, such as figure 2 As shown, the process may include the following steps:

[0116] Step 201: performing correlation-based clustering on queries to obtain query groups.

[0117] If identifying queries with questionable requirements in the search log is performed in parallel with determining hotspot queries, or first identifying hotspot queries and then identifying queries with questionable requirements from hotspot queries, the clustering objects of this step are: crawled searches query in the log.

[0118] If the query with questionable requirements is first identified in the search log, and then the hot query is determined among the queries with hot demand, then the clustering object in this step is: the query with questionable requirement identified in the search log.

[0119] After clustering, each query contained in each query group has a high correlation. ...

Embodiment 3

[0129] image 3 The flow chart of the method for searching relevant knowledge information provided by Embodiment 3 of the present invention, as shown in image 3 As shown, the method for searching relevant knowledge information may include the following steps:

[0130] Step 301: Receive the query input by the user.

[0131] Step 302: search for pages that match the keywords of the query; if a page that matches the keywords of the query on the knowledge question and answer platform is found, search for pages that match the keywords of the query on the knowledge question and answer platform The pages matching the keywords are included in the search results of the query and returned to the user.

[0132] based on figure 1 As shown in the process, when the search engine receives the user-input query sent by the browser, when searching the page according to the user-input query, the background has already followed the figure 1 The process shown simulates user questions and publ...

Abstract

The invention provides a method and a device acquiring and searching for relevant knowledge information. The method comprises: analyzing a search log to mine a hot-spot search query with a doubt requirement; forming a question by using the mined query and issuing the question on a page of a knowledge question and answer platform; and acquiring relevant knowledge information about the question through the page of the knowledge question and answer platform. When a query input by a user is received, a page matching with a keyword of the query is searched. If the page matching with the keyword of the query is found on the knowledge question and answer platform, the page matching with the keyword of the query on the knowledge question and answer platform is carried in a search result of the query and returned to the user. Through the present invention, relevant knowledge information can be rapidly and accurately provided for the user, and the user does not need to log in to the knowledge question and answer platform to issue a question and acquire relevant knowledge information until the question is answered.

Description

【Technical field】 [0001] The invention relates to the technical field of Internet communication, in particular to a method and device for acquiring and searching relevant knowledge information. 【Background technique】 [0002] With the rapid development of Internet technology, obtaining information and communicating with each other through the Internet has become a part of people's daily life. The knowledge question answering system is a system that uses communication functions to achieve information acquisition. Users can submit various questions in the knowledge question answering system through the webpage, query the status of the submitted questions, and decide which answer to use according to the status of the questions answered. Other users can view the questions by visiting this page and answer them according to their preferences and knowledge. [0003] However, after users ask questions on the knowledge question answering system, they need to wait for other users to ...
