Embodiment 1

[0062] Based on the limitations of the current technology, the embodiment of the present invention adopts ontology technology to abstract the smart home environment, and establishes the ontology model of the smart home. The model includes information such as device ontology, environment ontology, and user ontology. together to form a complete context. According to the query keyword input by the user, the constructed ontology model is queried through the query language and query algorithm, so as to obtain the ontology information related to the query keyword, the ontology information includes status information, service information or device information, etc.

[0063] This embodiment provides a processing flow of an ontology-based smart home semantic query method as follows: figure 1 As shown, the following processing steps are included:

[0064] Step S110, abstract the information in the smart home environment, abstract multiple ontologies, define the relevant attributes of e...

Embodiment 2

[0080] The processing flow of a context-oriented query method in an ontology model provided by this embodiment is as follows: Figure 4 As shown, the following processing steps are included:

[0081] Step S410, the user inputs an ontology model to be queried and a query keyword.

[0082] The query method is mainly based on the device ontology, user ontology, location ontology and context ontology in the ontology model to realize the query of the context in the smart home environment, that is, the query of the device status, user status and environment status.

[0083] The above-mentioned query keywords can uniquely correspond to a certain concept in the above-mentioned device ontology, user ontology, and location ontology. For example, to query the status of the user, you can select the user ontology and input a concept in the user ontology as the query keyword.

[0084] Step S420: Select a designated ontology in the ontology model according to the query keyword input by the ...

Embodiment 3

[0095] The processing flow of the query method for the services that meet the requirements and the devices that implement the services in the ontology model provided by this embodiment is as follows: Figure 5 As shown, the following processing steps are included:

[0096] Step S510, the user selects a demand ontology, and selects a concept in the demand ontology as a first query keyword.

[0097] Step S520 , query the requirement ontology according to the first query keyword, and obtain the specified concept in the requirement ontology, related instances of the specified concept, and all attribute characteristics of the specified concept.

[0098] Step S530: Select the value range corresponding to the couldBeSatisfiedBy attribute from all attribute characteristics of the specified concept in the requirement ontology, and select the specified concept in the service ontology that satisfies the value range as the second query keyword.

[0099] For example, the entertainment dem...

Abstract

The embodiment of the invention provides an ontology-based smart home semantic query method and an ontology-based smart home semantic query device. The method mainly includes the following steps: information in a smart home environment is abstracted, so that a plurality of ontologies are abstracted out, the related attributes of each ontology and the relation between the ontologies are defined, and an ontology model of the smart home is created; according to a query keyword inputted by a user, the ontology model is semantically queried, so that the related information, which corresponds to the query keyword, in the smart home environment is obtained. By creating the ontology model of the smart home, the embodiment of the invention can realize the query of status information of users or devices or the environment in the smart home environment according to the ontology model and the query of services satisfying demand and devices implementing the services in the smart home environment, consequently, the information in the entire smart home environment can be fully known, and the various devices in the smart home environment can be effectively and centrally managed.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to an ontology-based smart home semantic query method and device. Background technique [0002] Smart home refers to the use of advanced computer technology, network communication technology, and integrated wiring technology to organically combine various subsystems related to home life, and to make home life more comfortable, safe and effective through overall management. Compared with ordinary homes, smart homes not only have traditional living functions, but also provide a comfortable, safe, high-grade and pleasant family living space; they have also transformed from the original passive static structure into dynamic and intelligent tools, providing a full range of information interaction functions , to help families maintain smooth information exchange with the outside world, optimize people's lifestyles, help people effectively arrange time, enhance the safety and comfort of...
