Example Embodiment

[0030] The present invention will be described in detail below with reference to the drawings and specific implementations.

[0031] Such as figure 1 As shown, the present invention includes that the system includes a computer and an answering interface marked with a specific segmentation symbol; the computer runs a subjective question review system, and the review system includes a data preprocessing module, a clustering analysis module, a recommendation visualization module, Review the database.

[0032] Such as figure 2 As shown, the specific implementation of the data preprocessing module in the present invention is as follows:

[0033] The user submits student answers and uploads the answers to the review database. In this example, the open source word segmentation tool jieba (see:) can also be used opennlp (http: / / opennlp.apache.org / ) or nlpir (http: / / ictclas. nlpir.org / ) and a custom user dictionary built to segment the answers. Jieba is a commonly used word segmentation com...

Abstract

A subjective question marking system and method combining short text clustering and recommendation mechanism are disclosed. The system comprises a computer. The computer runs a subjective question marking system, and the marking system comprises a data preprocessing module, a clustering analysis module, a recommendation visualization module and a marking database. The invention is suitable for obtaining the marking data of the subjective questions, and is characterized in that the short text clustering and the recommendation mechanism are applied to the marking scene, thereby obtaining the marking result with higher reliability and stronger consistency; on the one hand, the problem that the credibility of the training automatic marking model is not high due to poor marking consistency canbe solved. On the other hand, the credibility of user marking behavior is improved, the score scale changes in the marking process are reduced, and the fairness of marking results is increased.

Description

technical field [0001] The invention belongs to the field of review data collection, specifically, a subjective question review system and method combined with short text clustering and recommendation mechanisms, the system can be applied to subjective question review and high-quality subjective question review data in primary and secondary schools Obtain. Background technique [0002] Subjective question review is an important part of students' learning and teaching, and it is an important way for teachers to understand students' knowledge mastery. At present, teacher review is also a very important step to realize automatic machine review. The current homework review method is single, mainly full-batch full-reform and intensive-batch fine-tune (Yu Taimeng. From "full batch full-reform" to "fine-batch and ingenious correction"[J]. Friends of Students (Junior High School Edition), 2011,09 :14.), homework platforms developed for this method are also emerging, such as homewor...
