Processing method and device for searching of natural language by remote sensing data

Abstract

The invention discloses a processing method and a device for searching of a natural language by remote sensing data. The method comprises the following steps: S1, inquiry statements of a user are segmented, and to-be-processed keywords are extracted from the segmented inquiry statements; S2, semantic digging is conducted to the to-be-processed keywords so that keyword groups in a standard format are obtained; and S3, semantic analysis is conducted to the keyword groups so that condition groups are obtained so as to serve as conditions for searching remote sensing data. According to the processing method and the device for searching of the natural language by the remote sensing data, a natural inquiry language of the remote sensing data is processed, the defects that an ordinary natural language has a disadvantage in analysis of a processing method, the natural inquiry language statements can be understood effectively and converted to inquiry condition groups corresponding to user intents, and therefore the problem in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of remote sensing data retrieval, in particular to a processing method and device for remote sensing data retrieval natural language which can be applied to a natural language-oriented remote sensing data retrieval system. Background technique [0002] Compared with controlled language, natural language is human language that has not been processed and normalized. The natural language-oriented query system can allow users to express questions in natural language such as words, words, sentences, and even paragraphs without being restricted by professional terms, and complete information query and retrieval. This query method is beneficial to the information retrieval of non-professionals, and provides technical support for the better application and popularization of the information retrieval system. At present, remote sensing data query generally provides a graphical query interface provided by the system. Users can ...

AI Technical Summary

Problems solved by technology

[0003] However, due to the complexity of natural language, how to correctly and fully understand natural query sentences is one of the important problems to be solved urgently for natural language retrieval systems.

Especially when the natural language retrieval system is applied to a certain professional field, the general natural language processing technology cannot well mine and understand the user's retrieval needs related to the professional field
