Problems solved by technology

[0004] The inventors found in the research that currently commonly used environmental information representation methods such as predicate logic representation, production rule representation and semantic web ontology representation mostly emphasize the concepts in the environment and the relationship between concepts. Not only is it difficult to express the characteristics of environmental information, but there are also problems such as high artificial participation in semantic information and insufficient knowledge reasoning ability, which cannot meet the needs of intelligent robot services.

Embodiment 1

[0039] This embodiment discloses an environment representation method in the intelligent service of a service robot. A standard and standardized environmental semantic information knowledge base is constructed by using the knowledge graph. In the subsequent service process of the robot, the structured knowledge of the knowledge base can be combined with the map. together to form a semantic map for use by robots.

[0040] In the specific implementation example, the construction of the knowledge base based on the knowledge map, please refer to the attached figure 1 shown, including:

[0041] Build a knowledge base based on the knowledge graph, and combine the knowledge obtained from the Internet with environmental information to form a unified expression. The construction of the knowledge base mainly includes the construction of the data layer and the construction of the concept layer, including the acquisition of entities and the extraction of concepts, where entities refer to...

Abstract

The invention discloses an environment characterization method in intelligent service of a service robot. Knowledge fusion based on vector characteristics is adopted for knowledge from different datasources, a knowledge reasoning algorithm based on a Markov logic network is adopted for further mining the implicit relation existing in the environment information, the autonomous development function of the knowledge base is achieved, and therefore expression work of the indoor environment information based on the knowledge graph is completed. Article relations among environments are stored in agraph form of the knowledge graph, and the search speed of the robot is increased by means of the efficient search capacity of the graph form.

Description

technical field [0001] The invention belongs to the technical field of robots, in particular to an environment representation method in the intelligent service of service robots. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The key for robots to complete intelligent service tasks in complex environments is efficient environmental information modeling. Usually, the environmental information faced by service robots when performing tasks has the characteristics of diversity, semantics, hierarchy, and relevance. The essence of environmental modeling is to encode these diverse and related information in a structured and unified form, and Based on these coding services, robots can understand the environment more comprehensively and reasonably, and then realize intelligent services. Therefore, an efficient environmental information represen...
