Problems solved by technology
[0004] However, the current method of interactive question and answer based on natural language may obtain a large amount of information that is not related to meteorological service knowledge through the network search of natural language interactive question and answer. Therefore, the accuracy of meteorological service knowledge obtained through network search is low, and it takes more time to identify relevant meteorological service knowledge, and the acquisition efficiency of meteorological service knowledge is not high.

The present invention provides a method and device for acquiring weather service knowledge, wherein the method for acquiring weather service knowledge includes: performing entity recognition and entity relationship extraction on natural language representation questions raised by users; extracting entities belonging to Meteorological entities in the field of meteorology; based on similarity algorithms, link meteorological entities to pre-built meteorological knowledge graphs; disambiguate entities linked to meteorological knowledge graphs based on the linking results of meteorological entities to meteorological knowledge graphs; After the disambiguation process is linked to the entity in the meteorological knowledge map, a database query statement is constructed, and the meteorological knowledge map is searched according to the constructed database query statement to obtain the weather service knowledge corresponding to the natural language representation problem. The acquisition efficiency of meteorological service knowledge can be improved.
Description
technical field [0001] The invention relates to the technical field of meteorological services, in particular to a method and device for acquiring knowledge of meteorological services. Background technique [0002] Natural language processing technology has been applied in all aspects of daily life and work, especially interactive question and answer based on natural language processing. Interactive question and answer can generate natural language answers according to the natural language questions of the questioner, which is intelligent and can save The cost of a large number of artificial seats is more and more widely used. [0003] At present, the interactive question and answer method based on natural language is widely used in life scenarios. Questions and answers are designed through preset rules, and answers are provided according to the rules, such as ordering meals and air tickets, etc., and the answers to questions are mainly searched through slot filling rules. ...
