Abstract

The invention discloses a natural language query method, a device and a system based on an ER model. The query method includes: receiving a keyword input by a client; Performing intention recognitionon the keyword to obtain an intention recognition result; Returning a data entry hit by a keyword according to an intention recognition result; Receiving a target entry selected by a client among thedata entries hit by the keyword; Searching data content associated with the target item in a database according to an ER model; Returning the data content found as a result of the query. The inventionperforms information retrieval based on natural language recognition and ER model technology, identifies the intention from the natural language input by a user, locates from a plurality of databasesof an enterprise, organizes corresponding data, provides data content to a user, reduces the threshold of data use and improves the use efficiency.

Description

technical field [0001] The invention relates to the application field of information management technology, in particular to an ER model-based natural language query method, device and system. Background technique [0002] With the vigorous development of digitalization, all kinds of enterprise data are exploding. But what we often see is that the data is distributed in different systems in different forms. When employees look for data, it is often difficult to effectively use the data after overcoming the communication barriers within the enterprise. This is due to the following reasons: first, the amount of data is huge, and information cannot be fully queried; second, the data is scattered in different systems, and it is necessary to be fully familiar with the system; third, in the face of specific business problems, specific support I don’t know where to get the data; fourth, the information system is often upgraded regularly, which requires employees to learn and mast...
