Abstract
Description
Technical Field
[0001] The present invention relates to the field of computer technology, and in particular to a method and system for intelligent collection and editing of knowledge in a work order system. Background Art
[0002] In modern enterprise operations, the work order system is an important tool for maintaining service quality and responding to customer needs. However, traditional work order processing methods often rely on manual operations, which are not only inefficient but also prone to errors. At the same time, it is difficult to automatically accumulate solutions / knowledge for work order solutions. Therefore, manual operation strategies are often adopted to identify hot issues / knowledge in work order analysis or keyword screening to achieve knowledge collection and editing, such as Figure 1 shown.
[0003] 1. The following is the difference between the knowledge collection and compilation method in the present invention and the "A method for intelligent extraction of small sample event elements based on clustering algorithm" (patent number: CN202410359544.0): The patent is a method for intelligent extraction of small sample event elements based on clustering algorithm, which uses the Word2Vec model to vectorize text data, clusters it through the K-means algorithm, and selects multiple samples with the highest information entropy similarity weight as representative samples of the cluster. It is mainly aimed at event extraction in small sample cases, and can also be used as a method for knowledge extraction. However, the patent directly processes text data, and there is a problem of low efficiency in clustering analysis.
[0004] 2. The knowledge collection and editing in "A method and system for generating question-answer pairs based on a large language model" (patent number: CN202410465219.2) is different from that in the present invention: the patent is a method for generating question-answer pairs based on a large language model, which mainly uses document knowledge data through triple enhancement and two-stage retrieval enhancement, and then uses a large model to generate question-answer pairs, which is a re-editing and processing of explicit knowledge. However, the patent directly processes explicit knowledge, and in order to take into account the influence of implicit knowledge, the generated question-answer pairs are not sufficiently relevant.
[0005] Existing knowledge collection and editing methods and systems have the following shortcomings in the hybrid search part:
[0006] (1) They often rely on preset rules and templates and cannot flexibly adapt to different work order contents and formats, and cannot recognize synonyms and similar expressions.
[0007] (2) When processing a large number of work orders, existing knowledge collection and editing methods and systems make manual analysis difficult and unable to quickly locate hot issues, resulting in low analysis efficiency.
[0008] (3) The analysis granularity is relatively coarse and not comprehensive enough to accurately quantify hot issues and knowledge, so the improvement brought to subsequent knowledge empowerment is poor.
[0009] (4) The analysis dimension is limited. It can only analyze through the work order content and the completed opinion, and cannot analyze and mine by combining information such as system error messages and chat records. Summary of the Invention
