Embodiment 1

[0094] figure 1 is the flow chart of the answer recommendation method provided in this embodiment, such as figure 1 As shown, the method includes:

[0095] Step S10, obtaining the text content of the question and the answer corresponding to the question, and segmenting the words to obtain the semantic unit of the question and the semantic unit of the answer.

[0096] A question may include multiple corresponding answers, and word segmentation and filtering are performed on the text content of the question and each answer to obtain the semantic units contained in the acquired question and each answer.

[0097] The present invention can perform word segmentation on the text content of the question or answer using existing word segmentation methods, such as N-gram word segmentation, forward maximum matching method, reverse maximum matching method, and the like. Taking N-grammatical segmentation as an example, unary division is performed to obtain each unary semantic unit, such ...

Embodiment 2

[0174] Figure 4 is a schematic diagram of the answer recommendation device provided in this embodiment. Such as Figure 4 As shown, the device includes:

[0175] The text acquisition module 10 is used to acquire the text content of the question and the answer corresponding to the question, and segment the words to obtain the semantic unit of the question and the semantic unit of the answer.

[0176] A question may include multiple corresponding answers, and word segmentation and filtering are performed on the text content of the question and each answer to obtain the semantic units contained in the acquired question and each answer.

[0177] The text acquisition module 10 can use existing word segmentation methods to segment the text content of the question or answer, such as N-gram word segmentation, forward maximum matching method, reverse maximum matching method, etc. Taking N-grammatical segmentation as an example, unary division is performed to obtain each unary seman...

Abstract

The present invention provides an answer recommendation method and device, wherein, the method includes: obtaining the text content of the question and the answer corresponding to the question, segmenting words to obtain the semantic unit of the question and the semantic unit of the answer; using the pre-established question domain dictionary, find out the weights of the semantic units of the questions in each category, and calculate the topic weights of the questions in each category; and, use the pre-established answer domain dictionary to find out the semantic units of the answers in weights in each category, respectively calculate the topic weights of the answers in each category; use the topic weights of the obtained questions and the topic weights of each answer to calculate the topic similarity between each answer and the question, according to The calculation result of the topic similarity recommends an answer. Compared with the prior art, the present invention generates a question domain dictionary and an answer domain dictionary respectively, which effectively improves the accuracy rate of question and answer for semantic similarity and improves the recall rate.

Description

【Technical field】 [0001] The invention relates to the technical field of Internet information processing, in particular to an answer recommendation method and device. 【Background technique】 [0002] With the continuous development of information and network technology, online interactive question-and-answer communities such as Baidu Zhizhi, Sina Aiwen, Google Q&A, Soso Ask, Yahoo Knowledge Hall, etc., are increasingly attracting people's attention. These online interactive question-and-answer communities provide a platform for netizens to interact and communicate. Users can freely ask questions, browse questions, answer questions, communicate with each other, and share knowledge. With the increasing number of users participating in the question-and-answer community, the number of candidate answers increases accordingly, and the question-and-answer community usually automatically sorts the answers in order to recommend optimal answers for users. [0003] In the automatic sor...
