Personal computing systems like e.g., laptop, smartphone, and smartwatches are nowadays ubiquitous in people's everyday life. People use such systems not only for communicating or searching for information, but also as digital companions, able to track and support their daily activities such as sleep, food intake, physical exercise and even work. Sensors embedded in personal computing systems...

The purpose of this thesis is to create clusters from historical data with and without domain knowledge. The method used to cluster the data with domain knowledge is a pattern matching sequence and the method done without domain knowledge is a clustering algorithm that will be defined later. The data had to be retrieved from four old databases, then prepared to be clustered. A...

Wikidata is rapidly emerging as a key resource for a multitude of online tasks such as Speech Recognition, Entity Linking, Question Answering, or Semantic Search. The value of Wikidata is directly linked to the rich information associated with each entity – that is, the properties describing each entity as well as the relationships to other entities. Despite the tremendous manual and...

The vision of Machine Reading is to automatically understand written text and transform the contained information into machine-readable representations. This thesis approaches this challenge in particular in the context of commercial organizations. Here, an abundance of domain-specific knowledge is frequently stored in unstructured text resources. Existing methods often fail in this scenario,...

With the end of Moore's law and Dennard scaling, applications no longer enjoy performance improvements by simply waiting for the next generation of CPUs. This has led to the rise of domain-specific computing. As developers try to squeeze more performance out of applications, they have offloaded application functionality to specialized hardware, such as GPUs, FPGAs and ASICs. Programming these...

Collaborative Knowledge Graph platforms allow humans and automated scripts to collaborate in creating, updating and interlinking entities and facts. To ensure both the completeness of the data as well as a uniform coverage of the different topics, it is crucial to identify underrepresented classes in the Knowledge Graph. In this paper, we tackle this problem by developing statistical techniques...
