Abstract

The invention discloses a power grid equipment word segmentation dictionary and a fault case library construction method. The method comprises the steps: constructing a power grid field word segmentation dictionary, carrying out the format conversion and word segmentation of fault case data, carrying out the analysis and generation of structured power grid equipment fault cases, feature tags, keyword clouds and association rules from text data through employing a plurality of technical means. and designing a relational database Schema for the information, taking a report as a main key, and storing the text information and information such as pictures, authors and the like reserved in preprocessing in a library to form a power grid equipment fault case library. According to the method, the word segmentation accuracy of the power grid field text is improved, the structured case database enables retrieval according to case contents to be more accurate, the feature tags in the fault case database serve as item sets, effective association rules of faults are sorted and mined, the method can be used for fault early warning, and the blank of application of the power grid field text analysis technology is filled up. The application value of corpora in the power grid field is improved, and the consulting cost is reduced.
