Abstract

The invention discloses an NLP-based domain model extraction method for airborne display control system requirements. The method comprises the steps of S1, preprocessing an input requirement text; S2,analyzing and extracting a dependency relationship and a co-exponential analysis relationship in the requirement text; S3, according to a set composed of verb phrases and noun phrases, a dependency item analysis result and a co-reference analysis result, improving the dependency relationship of words to semantic unit dependency, and triggering rules to construct a domain model; and S4, visualizing the domain model constructed in the step S3. Domain model extraction is performed on airborne display and control system requirements according to existing model extraction rules,, the effectivenessof the rules in the aspect of airborne display and control system requirement domain model extraction is demonstrated through experiments, and the method has the advantages of being high in correlation, good in application prospect and the like.

Description

technical field [0001] The present invention relates to the technical field of airborne display and control system requirements processing, in particular to an NLP-based method for extracting domain models of airborne display and control system requirements. Background technique [0002] As the scale of the avionics system continues to increase, the complexity also increases sharply, so the requirements for the reliability, real-time, and interactive design of the entire avionics system are also higher. Display and control system (referred to as display and control system), as the core part of modern aircraft integrated avionics system, is the upper management and processing software of all electronic equipment. The complexity of the requirements of the airborne display and control system means that the requirements engineer will not be able to quickly obtain and accurately express these requirements. Without any prompts and guidance, the requirements engineer cannot immedia...
