Embodiment 1

[0059] In the absence of user registration information, historical service invocation information and sensitive user data privacy, in order to realize the privacy-protected personalized entity service search in the Internet of Things environment, this application proposes a privacy-protected Internet of Things entity service search method. like figure 1 shown, including:

[0060] S1. Using the multi-source heterogeneous information of the IoT entity service provider, the representation vector of the IoT entity service is obtained through representation learning; the multi-source heterogeneous information includes social networks, description documents and service attribute labels;

[0061] In S1, the representation vector is low-dimensional, dense and rich in heterogeneous information.

[0062] S2. Combine the representation vector and attribute label of the IoT entity service to establish a data graph representation model of the IoT entity service;

[0063] S3. Mining user ...

Abstract

The invention relates to a privacy-protected Internet of Things entity service search method, which comprises the following steps of: obtaining a representation vector of an Internet of Things entity service through representation learning by utilizing multi-source heterogeneous information of an Internet of Things entity service provider; establishing a data graph representation model of the Internet of Things entity service; establishing a personalized search sorting model; providing a candidate entity service search sorting list for the user; and obtaining a personalized search result of privacy protection. The method has the beneficial effects that the association fusion graph of the heterogeneous Internet of Things entity services is established, and the search intention of the user is deeply mined, so that high-quality search results which vary from person to person for the Internet of Things entity services are realized, and the service satisfaction degree of the user is improved.

Description

technical field [0001] The invention relates to the field of Internet of Things search, more specifically, it relates to a privacy-protected Internet of Things entity service search method. Background technique [0002] The rapid development and popularization of technologies such as sensors, wireless communication and ubiquitous computing make a large number of physical objects with sensing, computing and communication functions widely exist in the Internet of Things. Vehicles, environmental monitoring devices, wearable devices, and various daily necessities in smart homes all over the world are all physical objects, and all behaviors of people and things can be perceived by various physical objects. It is foreseeable that, just as we currently use web search engines to find information on the Internet, with various application fields (such as environmental monitoring, smart home, smart logistics, and smart construction sites, etc.), there is an increasing demand for servic...
