Embodiment 1
[0038] In this implementation, a leaderless group discussion system is disclosed, comprising: a voice capture module, an audio conversion module and a keyword extraction module, wherein the voice capture module, the audio conversion module and the keyword extraction module are connected in sequence;
[0039] The voice capture module: used to capture the speech of the speaker in the form of speech;
[0040] The audio conversion module: for converting the captured speech in the form of speech into a speech in the form of text;
[0041] The keyword extraction module is used to perform word segmentation processing on the speech in the form of text, and filter out the stop words in the speech during the word segmentation processing, retain the words with the specified part of speech, and obtain the filtered word segmentation set; The word segmentation in the word segmentation set constructs a vertex set, and uses the co-occurrence relationship to construct an edge between any two p...
Embodiment 2
[0044]The second embodiment is a preferred embodiment of the first embodiment, and the difference between it and the first embodiment is that the specific structure of the leaderless group discussion system is expanded:
[0045] In this embodiment, as Figure 4 As shown, a leaderless group discussion system is disclosed, including: a microphone, a camera, and a main control terminal; wherein the main control terminal includes an audio conversion module, a keyword extraction module, and a sensitive word extraction module;
[0046] Students click the start speaking button and start the microphone to record. After clicking the end speech, the audio and video files are transferred to the main control terminal, and ffmpeg is used in the main control terminal to separate the audio files and analyze them.
[0047] The audio-to-text part uses the relevant interface of Tencent Cloud speech recognition, through which the audio file is directly converted into the corresponding text, and ...

Abstract
The invention discloses a leadless group discussion system, which comprises the following steps of: converting a captured speech in a voice form into a speech in a text form, performing word segmentation processing on the speech in the text form, and filtering out stop words in the speech and retaining words with specified parts of speech in the word segmentation processing process to obtain a filtered word segmentation set; constructing a vertex set by using the segmented words in the filtered segmented word set, constructing an edge between any two points of the vertex set by adopting a co-occurrence relationship to obtain candidate keyword graphs of the filtered segmented word set, calculating the weight of each vertex set in the candidate keyword graphs, and sorting the weights of the candidate keyword graphs from large to small to obtain the candidate keyword graphs of the filtered segmented word set. The N vertexes with the weight values in the top are selected as the keywords of the speaking, so that an interviewer or an examiner is assisted to quickly understand whether the speaking of the interviewer deviates from the theme or not by extracting the keywords, and the interview ability of the interviewer or the interview efficiency of the interviewer is assisted to be improved.
Description
technical field [0001] The invention relates to the field of only interviews, in particular to a leaderless group discussion system. Background technique [0002] Leaderless Group Discussion is an evaluation technique often used in the evaluation center technology, which uses scenario simulation to conduct group interviews for candidates. The leaderless group consists of a certain number of candidates (6-9 people) to discuss work-related issues for about an hour. During the discussion, no leader is designated, nor the position where the testee should sit. , let the subjects arrange their own organizations, and the evaluators will observe whether the candidates' abilities and qualities in various aspects such as organizational coordination ability, oral expression ability, debate persuasion ability and so on meet the requirements of the proposed position, as well as the degree of self-confidence, enterprising spirit, emotion, etc. Whether the personality characteristics such...
