*4.4. Semantic Enrichment*

The IoTCrawler framework is capable of adding new meta-information to known data and data sources. For this purpose, the Semantic Enrichment (SE) is being used. Currently, the component contains two parts, but can be extended further: the QoI Analyser and the Pattern Extractor, where the first one is responsible to add information about QoI to a data stream and the second one to extract patterns and therefore learn additional information from a stream.
