Problems solved by technology

One is: the evaluation of concept similarity is not comprehensive enough; the other is: when using traditional methods to calculate concept similarity, the similarity between each concept pair in the ontology is usually calculated, the workload is heavy, and it cannot adapt to the current situation. Explosive development of information transmission and interaction needs of emerging industries
The third is: when constructing ontology, you must have certain basic background knowledge. In many emerging fields, you are facing the problem of lack of background knowledge and matching failure. As a result, ontology mapping can only adapt to tasks in certain specific fields and cannot adapt to future development. needs

Embodiment Construction

[0046] The technical solutions in the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments of the present invention. The described embodiments are only some of the embodiments of the invention.

[0047] The technical scheme that the present invention solves the problems of the technologies described above is:

[0048] Such as figure 1 As shown, the ontology mapping method in the field of robotics includes parsing the matching concept pairs of the ontology, screening out the candidate concept set according to the semantic similarity, calculating the comprehensive similarity of the concept pairs, and outputting the mapping result. The specific operation process is as follows:

[0049] Step 1: Extract ontology O1 and ontology O2 from the ontology library, and input them into the ontology parsing module.

[0050] Step 2: The ontology parsing module first obtains the concept pair to be matched, and j...

Abstract

The invention claims a robot data interoperation domain ontology mapping method based on semantic similarity, which comprises the steps of analyzing matching concept pairs of the ontology, screening out an alternative concept set according to semantic similarity, calculating the comprehensive similarity of the concept pairs, and outputting a mapping result. This method solves the key problem of data interoperability of heterogeneous robot systems with ontology theory, that is, how to find the mapping relationship between ontologies. This method is mainly applied to data interoperability in manufacturing heterogeneous systems, complete the mapping of robot domain ontology, Compared with the traditional manual method, the ontology mapping construction process is more convenient and quick, the workload of mapping process is reduced, and the expansibility and stability of the ontology in the robot domain can be improved.

Description

technical field [0001] The invention belongs to the ontology mapping technology in the field of manufacturing informatization, and belongs to the aspect of robot data interoperation, in particular to an ontology mapping method in the field of robot data interoperation based on semantic similarity. Background technique [0002] With the advent of the information age of the manufacturing industry, information sharing has become an important technology for the development of information technology. However, most manufacturing equipment is only developed for a specific working environment, and some more and more complex tasks require the cooperation of multiple devices to complete. There are many scenarios where various devices work together in industrial sites, but our country’s technical foundation in this area is not strong. With the continuous development of technology, people have put forward higher requirements for data sharing, hoping to eliminate the gap between heteroge...
