specific Embodiment approach

[0131] In detail, the specific implementation of each module of the key information extraction device 100 is as follows:

[0132] Step 1. The entity recognition module 101 obtains the question text and the answer text retrieved according to the question text, performs word segmentation on the answer text, and performs entity recognition processing on the word-segmented answer text to obtain an entity set.

[0133] In the embodiment of the present invention, the question text refers to questions in different fields entered by the user in the search engine, and the answer text refers to the answer corresponding to the question text retrieved from the search engine. For example, the embodiment of the present invention In , the question text may be a question related to the medical field.

[0134] In an application scenario of the present invention, the question text is "what can be done to treat premature heartbeat?" The answer text is: "The heart is the upper central link of the...

Abstract

The invention relates to an intelligent decision making technology, and discloses a key information extraction method, which comprises the following steps of: carrying out word segmentation on an answer text, carrying out entity recognition processing on the answer text after word segmentation to obtain an entity set, screening a concept entity set from the entity set, constructing an initial concept graph according to the concept entity set and the answer text, initializing vertexes in the initial conceptual graph to obtain a standard conceptual graph, performing image convolution on the standard conceptual graph to obtain a vertex weight vector, calculating a semantic vector according to the first attention weight, the second attention weight and the vertexes in the initial conceptual graph, and according to the semantic vector semantic text, marking the semantic text as key information in the answer text. In addition, the invention also relates to a block chain technology, and the entity set can be stored in nodes of a block chain. The invention further discloses a key information extraction device, an electronic device and a storage medium. The problem that the accuracy of key information extraction is low can be solved.

Description

technical field [0001] The invention relates to the technical field of intelligent decision-making, in particular to a key information extraction method, device, electronic equipment and medium. Background technique [0002] With the development of search engine technology, the current online search engines can retrieve a large amount of rich and relevant information according to the questions entered by users. For example, online search engines have a large amount of health-related information, which is very attractive to users with medical problems. , the user can enter a question to get the relevant answer. However, most of the answers retrieved by online search engines are very long, which is inconvenient for users to directly understand the key information. Therefore, the desired answers cannot be obtained quickly and accurately. Contents of the invention [0003] The present invention provides a key information extraction method, device and computer-readable storage...
