[0006] However, Lucene's word frequency statistics are used for the calculation of hit result scores, not as overall statistics of data resources
Solr's word frequency statistics are used to realize the automatic completion function. Although it is used as an overall statistics of data resources, for each information unit, if there are multiple target words in multiple fields (ie "domain"), it is only calculated once. It belongs to coarse-grained statistics, and the accuracy of statistics is poor

The present invention provides a hot word analysis and statistics system and method, wherein the hot word analysis system includes: an analysis topic module for determining analysis data sources, defining analysis topics, and defining the data type of each domain; a focus vocabulary module , used to form the sequence of concerned vocabulary; the word segmentation service module is used to extract the data information in the corresponding domain, and segment the data information according to the sequence of concerned vocabulary to generate the sequence of word elements; the index service module is used to record each word The index position of the element in the corresponding domain and the data information corresponding to each word element are recorded, and the word element index file is generated; the word element statistics module is used to count the number of each word element; the hot word analysis module, the generated hot words The related information and the word frequency of hot words are fed back to the user. It realizes the accurate statistics of hot words and the index storage of the association relationship of hot words, solves the requirement of analyzing hot words by class, and improves the accuracy of hot word statistics.
Description
technical field [0001] The present invention relates to the technical field of data processing, in particular to a hot word analysis and statistics system and method. Background technique [0002] With the continuous improvement of the level of informatization, people's demand for data is no longer limited to simple data acquisition and data retrieval, but more attention is paid to using the collected information to discover and solve hidden problems. For example, in the field of public security technology, public security decision-makers pay more attention to generating hot words from the collected information through technical means such as text analysis and mining technology, and then solve business problems through statistical analysis results of hot words. [0003] Hot words are hot words. Simply put, when the word frequency of a word reaches a certain threshold, it is called a hot word. As a lexical phenomenon, the popularity of hot words reflects the issues and thing...
