Internet of Things (IoT) is the future of ubiquitous and personalised intelligent service delivery. It consists of interconnected, addressable and communicating objects, which are embedded in our environments. To realize this new and promising generation of ubiquitous systems, the IoT's 'smart' objects should be supported with intelligent platforms for data acquisition, preprocessing, classification, modelling, reasoning and inference including context distribution. However, some current IoT systems lack these capabilities: they provide only the functionality for obtaining raw sensor data. In this paper, we propose a framework towards deriving high-level context information from streams of raw IoT sensor data, using artificial neural networks (ANN) as context recognition model. Before building the model, the data was preprocessed using weighted average low-pass filtering and a sliding window with overlapping algorithm. From the resulting windows, statistical features were extracted as vectors, which were used to train the ANN model. Evaluations of the proposed system show that it has between 87.3% and 98.1% accuracies.
