Scientists always face difficulties dealing with disjointed information. There is a need for a standardized and robust way to represent and exchange knowledge. Ontology has been widely used for this purpose. However, since research involves semantics and operations, we need to conceptualize both of them. In this thesis, we propose ReShare to provide a solution for this problem. Maximizing utilization while preserving the semantics is one of the main challenges when the heterogeneous knowledge is combined. Therefore, operational annotations were designed to allow generic object modeling, binding and representation. Furthermore, a test bed is developed and preliminary results are presented to show the usefulness and robustness of our approach. Moreover, two aggregation techniques for fusing ontology matchers are investigated as an initial work for building an algorithm which converts descriptive ontologies into operational ones.

Ericsson is one of the world leaders in radio network technology and are spending a lot of resources on research in this area. This produces big amounts of data and there is a desire for tools that allows the researchers to investigate and present the data in a user friendly way. This is the motivation behind Elsa GVP, Ericsson’s visualization platform, which facilitates the production of interactive visualizations. The platform handles database connections and provides a number of visual components that can be used in an interactive visualization, such as bar charts, scatter plots and maps. Although Elsa GVP certainly makes the production of an interactive visualization speedier it is still a time consuming task and requires expert knowledge. Therefore, there is a desire to make the entire process easier and more user-friendly so that any employee can construct an interactive visualization. This is the motivation behind this master thesis work whose main objective is to investigate how to reduce the amount of work required to produce an interactive visualization by providing an intuitive graphical user interface.
