METHOD AND SYSTEM FOR SELECTING THINGS BASED ON QUALITY OF SERVICE IN WEB OF THINGS
First Claim
1. A method for recommending a predetermined thing to a user in a web of things environment, the method comprising:
- (a) obtaining web log data and metadata of at least one thing;
(b) computing QoS (Quality of Service) features of the thing from the web log data and metadata;
(c) in response to obtaining user'"'"'s review information on the thing, computing QoS grade information on the thing from the review information; and
(d) generating a rule for predicting a QoS grade for a thing for which there is no review information with reference to the QoS grade information on the thing and the QoS features of the thing.

10. A system for recommending proper things to a user in a web of things environment, the system comprising:
-
a QoS features generator configured to obtain web log data and metadata of at least one thing, and to compute QoS features of the thing from the web log data and metadata; a QoS classifier generator configured to generate a QoS grade classifier for obtaining user'"'"'s review information on the thing, for computing QoS grade information on the thing from the review information, and for predicting a QoS grade for a thing for which there is no review information with reference to the QoS grade information on the thing and the QoS features of the thing; and a thing recommender configured to, in response to receiving a request to provide a web of things service from a user, search a list of things and compute QoS features for each of the things, input the QoS features of each of the things to the rule to predict a QoS grade for each of the things, and recommend a thing having a high QoS grade to the user. - View Dependent Claims (11, 12)
