[0041] This embodiment provides a method for automatically generating distracting items in multiple-choice questions for the investigation of confusing words. The method can be implemented by an electronic device, and the electronic device can be a terminal or a server. The execution flow of the multiple-choice distractor automatic generation method for confusing words is as follows: figure 1 shown, including the following steps:

[0042] S1. Obtain the stem and the investigation word of the multiple-choice question to be generated as the interference item, and the first candidate word set corresponding to the investigation word; wherein, the first candidate word set includes a plurality of interference item candidate words;

[0043] It should be noted that the interference item candidate words are words related to the investigation word, and the method for automatically generating interference items for multiple-choice questions provided in this embodiment is to automatically...

Abstract

The invention discloses a method and device for automatically generating interference items of choice questions for investigation of confusable words, and the method comprises the steps: generating a word vector through pre-trained Word2vec, and selecting N candidate words through calculating the similarity; respectively substituting the investigation word and the N candidate words into the question stem, generating context-related word vectors through a pre-trained BERT model, and excluding words with too high similarity to obtain M candidate words; and clustering the M candidate words, then selecting the word with the highest similarity with the inspection word in each class cluster as a representative to obtain Q candidate words, and finally, according to the similarity, selecting a proper number of interference items from the Q candidate words. The scheme provided by the invention has the advantages of high efficiency, strong scientificity, capability of ensuring diversity of interference terms and the like.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a method and device for automatically generating interference items of multiple choice questions for the investigation of confusing words. Background technique [0002] In the process of language teaching, multiple-choice questions are an important form of examination questions. The distracting items of the question types based on the investigation of confusing words are usually confusing words. The most critical part of the proposition is the generation of distracting items. Scientific and efficient generation of distractors is an effective support for current language teaching assessment. [0003] The currently adopted technical solutions are: (according to the technical depth) [0004] (1) Teachers construct interference items based on experience, which is the current main working method. [0005] (2) Collect a set of candidate items related to the invest...
