Example Embodiment

[0023] The present invention is a method for describing a spatial entity object based on a relationship. The method specifically includes the definition of the spatial entity object and the description of the spatial region relationship;

[0024] 1. Description of the definition of spatial entity objects:

[0025] Assume Is a collection of entities in a space, an entity object defined as,

[0026]

[0027] among them,

[0028] (1) , , And all Are all Directly contains, Representation entity And entity Spatial relationship .

[0029] (2) , , And all Direct inclusion , Representation entity And entity Spatial relationship .

[0030] (3) , , , Is a triple, representing the entity And entity Have a relationship .

[0031] It can be seen from the definition that a spatial entity knowledge description model is a triplet ,among them , , Respectively represent spatial entities Internal information, spatial entity Inheritance information, and relationship infor...

Abstract

The invention discloses a method for describing space entity knowledge based on relations. In the prior art, the ability of effective organizing and expressing in space knowledge is still weak, the description for knowledge and semantic of information is lacked, so as to be in a condition that data is rich but the knowledge is lacked, and a robot is different to understand and apply. The method particularly comprises the defining for space entity objects and the describing for space area relations, and builds a universal space knowledge mold and a description method by abstractly defining the relations between environment entities, wherein the mold has space semantic information, and can better conduct organizing, searching, inferring, and analyzing for space data.

Description

technical field [0001] The invention belongs to the field of information science, especially the field of intelligence theory and its technical application, and focuses on the description model of spatial entity knowledge. Background technique [0002] In recent years, ontology has gradually become the core issue of common concern in the fields of knowledge engineering, artificial intelligence and semantic information. With the development of robot technology, the collection and application of space environment information by robots has been promoted, and various forms of environment description models have been obtained. However, the ability to effectively organize and express spatial knowledge is still weak, lacking knowledge of information and semantic description, and in a situation where data is abundant but knowledge is lacking, robots are also difficult to understand and apply. Therefore, a new environmental knowledge description model is proposed, which can express...
