what are the best references for learning IoT ontologies and how they could be used for auto-discovery of Smart Things (SThs) integration in the IoT network. and how to building a frame work that use them for searching in the IoT.
Some of our work on IoT ontologies (thanks Ameer Sameer for the citations):
Ontology for IoT enties, resources and services: http://epubs.surrey.ac.uk/127271/
The above ontology was used in this IoT platform: http://epubs.surrey.ac.uk/531903/ and for associating IoT objects with services: http://epubs.surrey.ac.uk/805573/
