Embodiment Construction

[0024] Several key technologies involved in the present invention are jieba word segmentation, Word2Vec model, K-means clustering and LSTM-DSSM deep learning model.

[0025] 1. Jieba participle

[0026] jieba is currently the best Chinese word segmentation component for Python. It mainly has the following three features. 1. Support 3 participle word mode

[0027] Mode: exact mode, full mode, search engine mode. 2. Support traditional word segmentation. 3. Support custom dictionary.

[0028] 2. Word2Vec model

[0029] Word2Vec, is a group of related models used to generate word vectors. These models are shallow, two-layer neural networks that are trained to reconstruct the linguistic text. The network is represented in terms of words and needs to guess the input words in adjacent positions. Under the assumption of the bag-of-words model in Word2Vec, the order of words is unimportant. After the training is completed, the Word2Vec model can be used to map each word to a v...

Abstract

A crowdsourcing test report similarity detection method based on natural language processing adopts a natural language processing technology to detect the similarity of complex test reports submitted by crowdsourcing workers, and has the function of performing Chinese word segmentation, stop word removal and other preprocessing on the crowdsourcing reports. Sentences represented by the preprocessed phrases are represented as word vectors by utilizing a Word2Vec technology, a cosine similarity measurement mode is selected to calculate the distance between the word vectors, training is performed by adopting a semantic model trained according to a large amount of previous crowd test report data, and then each word vector is taken as input of K-Means clustering analysis, and clustering analysis is carried out on each word vector, and similar reports are classified into the same class according to a set similarity threshold, so that the similarity between the crowdsourcing test reports can be accurately measured.

Description

technical field [0001] The invention belongs to the field of software engineering, is an application of natural language processing in the field of software engineering, and is used for detecting code similarity. Background technique [0002] The detection of similar crowdsourced test reports is a key technology to improve the utilization rate of crowdtest reports and reduce the workload of testers reading repeated reports. The crowdsourcing test report is the result that the crowdsourcing workers feedback to the testers after completing the tasks set by the initiator, and the testers guide the reproduction and location of the bug based on the crowdsourcing report. If there are a lot of repeated content describing the same bug content in the public test report, testers cannot know in advance whether the bug described in the report is mentioned before before reading, so testers need to waste a lot of time In reading duplicate reports, this is not helpful for testers to repro...
