Problems solved by technology

[0003] At present, for answer-choice questions, the method of determining the correct answer based on similarity or correlation is mainly used. This method determines the correct answer by calculating the most similarity or correlation between the options and the sentences of the background material. However, in the semantic The above-equivalent sentences are often expressed in different syntactic forms. The method based on similarity and correlation can only find sentences with a high similarity to the optional grammatical

Embodiment 1

[0044] Such as figure 2 As shown, the reading robot in this embodiment performs the answer selection method for reading comprehension, including:

[0045] 101. Obtain background material, questions based on the background material, and multiple options for the questions.

[0046] 102. Obtain the topic of each paragraph in the reading comprehension document based on the topic reasoning model, and locate the paragraphs related to the topic according to the core information of the topic.

[0047] Specifically, in view of the different description content of different paragraphs in the article, the topic of each paragraph in the reading comprehension document is obtained sequentially based on the LDA algorithm. For any article, the number of topics that is the same as the number of paragraphs in the article can be obtained. For a given document-related question stem, the elimination strategy is used to extract the core information of the question stem, that is, the secondary, su...

Embodiment 2

[0080] Such as figure 1As shown, the answer selection system for reading comprehension by a reading robot in this embodiment includes: a paragraph positioning unit, an evidence material acquisition unit, a semantic consistency analysis unit, and an answer selection unit.

Abstract

The invention discloses an answer selection method and system for allowing a reading robot to perform reading comprehension, which can improve the accuracy of answer selection while a robot performs reading comprehension. The answer selection method for allowing a reading robot to perform reading comprehension includes: positioning a paragraph associated with a question; adopting a bag of words model to extract a sentence having the most matching words with options as evidence materials; analyzing the semantic consistency of the options and the evidence materials; and selecting an optimal answer to the question according to the consistency analysis result. The answer selection method and system can applied to the reading robot, and can intelligent answer the selected question through automatic analysis and deduction.

Description

technical field [0001] The invention relates to the field of natural language processing research, in particular to an answer selection method and system for reading comprehension by a reading robot. technical background [0002] Reading comprehension is an important way for people to obtain information from a large amount of text. Many times, users do not want to browse the full text, but want to know the exact answer to a certain question. Reading comprehension question answering technology emerged as the times require. In the reading comprehension question and answer, there is a type of selective reading comprehension, that is, a question is asked based on the background material of reading comprehension, and multiple options are provided for the question, and the computer is required to automatically "read" a piece of material. Choose the correct answer from multiple candidate answers based on your "understanding" of the material. In the field of natural language, the m...
