Abstract: The evergrowing number of small devices with sensing capabilities produce massive amounts of diverse data. However, it becomes increasingly difficult to manage all these new data sources. Currently there is no single way to represent, share, and understand IoT data, leading to information silos that hinder the realization of complex IoT/M2M scenarios. IoT/M2M scenarios can only achieve their full potential when the devices become intelligent: work and learn together with minimal human intervention. We developed methods to estimate semantic similarity based on distributional profiles, cluster algorithm were used to learn semantic categories and improve the model accuracy. In this paper we discuss the impact of the cluster algorithm and respective heuristic to estimate inital parameters in the task of learning semantic categories. Our evaluation has shown that k-means combined with silhouette method achieved the higher result.
