Embodiment Construction

[0054] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0055] Aiming at the problems of low recall rate and precision rate of the existing keyword-based device search method, the present invention provides a device search method based on domain ontology in smart home.

[0056] like figure 1 As shown, the device search method based on domain ontology in the smart home provided by the embodiment of the present invention includes:

[0057] S101. Obtain the established smart home domain ontology model;

[0058] S102, reasoning the smart home ontology according to the acquired ontology model of the smart home domain, and obtaining the implicit relationship of the smart home ontology;

[0059] S103. Construct an index according to the device information stored in the preset device database to obtain an index tab...

Abstract

The invention provides a domain ontology-based equipment search method in smart hole, and aims at improving the recall ratio and precision ratio. The method comprises the following steps of: obtainingand established smart home domain ontology model; reasoning a smart home ontology according to the obtained smart home domain ontology model; so as to obtain a smart home ontology implication relation; constructing indexes according to equipment information stored in a preset equipment database so as to obtain an index table; and obtaining a query word input by a user, extending the query word byutilizing a smart home ontology-based semantic extension and Tongyici Cilin-based semantic extension combined method according to the obtained smart home ontology implication relation, searching theindex table and returning a corresponding equipment record. The method is suitable for equipment search operations in the internet of things.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a device search method based on domain ontology in smart home. Background technique [0002] With the rapid development of science and technology, the devices in the smart home field have shown exponential growth, and hundreds of sensors and actuators with different functions have begun to appear in the user's living environment. [0003] Due to the complexity of the environment and the relationship between various elements in the smart home, the keyword-based device search method used in the prior art cannot accurately understand the intention of the user's input, resulting in low recall and precision of the search method, which cannot be used for users. Provide satisfactory search results. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a device search method based on domain ontology in smart home, so as to solve the prob...
