The invention discloses a data query method and device based on a natural language text and computer equipment, relates to the technical field of artificial intelligence, and can solve the problems that when a natural language is used for information search, the conversion accuracy is low, a converted database execution language is likely to have deviation, and thus the search result of the information is not accurate enough. The method comprises the following steps: preprocessing each preset data table in a database, and extracting a first word feature and a first label feature of each preset data table; receiving a natural language text used for querying the table data, performing text feature extraction on the natural language text, and determining a second word feature and a second tag feature corresponding to the natural language text; and according to the first word feature and the first tag feature of each preset data table and the second word feature and the second tag feature corresponding to the natural language text, screening a target data table with the highest matching degree with the natural language text from the preset data tables based on a preset screening rule.
Description
Technical field [0001] The present application relates to the field of artificial intelligence, and in particular, a data query method, apparatus, and computer equipment based on natural language text. Background technique [0002] As the data size is increasing, how to improve the public, especially non-professionals, the ability to use data, and provide friendly and convenient query retrieval services, becoming a key issue to be resolved. The research of this problem is of great significance for promoting my country's data open process and promoting big data development. [0003] Natural language is a natural form of people's expression. If you can automatically convert natural language queries to query statements, it is convenient to meet the user's query requirements. However, natural language is greatly challenging for accurate query conversion in expression of fuzziness and abstraction and analysis of structural query languages. [0004] In the process of information search...
