Information aggregation method facing total system information management based on circumstances and semantics

Abstract

The present invention discloses an information aggregation method facing total system information management based on circumstances and semantics. The method comprises the steps of: achieving an information registration discovery mechanism, performing RDF description of air control business information according to a metadata model, analyzing business circumstance factors such as air control application targets, user demands, behaviors, time and places, constructing a circumstance model based on a body, when a user demands object information, associating with the circumstance model, automatically performing Web service discovery through a circumstances and semantic tag matching algorithm, combining mapping tables on a word list and the body to achieve matching of the basic description attributes, quality attributes and function attributes to associate with the corresponding data, and finally, after information aggregation fusion, forming business object information products meeting thecircumstances. The information aggregation method facing total system information management based on circumstances and semantics can achieve data cross-domain information sharing between different interested parties of the air control to construct a uniform information coordination environment and form a uniform situation perception capacity.

Description

technical field [0001] The invention belongs to the field of air traffic information management, and in particular relates to an information aggregation method based on scenarios and semantics for SWIM (System Wide Information Management) of air traffic control. Background technique [0002] With the development and wider application of air traffic management information integration technology, air traffic management related users have higher and higher requirements for information, especially the advanced concept of next-generation air traffic management and the ASBU block upgrade of ICAO planning, and put forward high-level requirements for information sharing and management. It is required to provide a globally common aviation data standard and reference system, allowing mutual integration and integration, and providing comprehensive situational awareness; implementing system-wide information management (SWIM) to provide credible and quality-assured information to the air...

AI Technical Summary

Problems solved by technology

[0007] However, the existing technologies or methods focus on the simple aggregation and integration of data in the field of media or data processing under single conditions, and cannot realize the large-scale information system in the field of air traffic control, the variety and heterogeneity of data, and the integration of complex scenarios. Intelligent information aggregation requirements

Existing methods cannot solve the problems of cross-domain information sharing, building a unified information collaboration environment, forming a unified situational awareness, service intelligent discovery and data intelligent aggregation among different air traffic control stakeholders
