|Title of the thesis:||Knowledge-based software representation, querying and visualization|
|Summary:||In the recent years information visualization became very important as it allows us to gain insight into large amounts of data. Better information comprehension can be obtained by observing graphical representations of data, which may reveal hidden patterns. Among various data types that can be visualized, software is a suitable candidate due to software's intangibility. In our work we focused on the visualization of software artifacts and their interconnections. We propose a software visualization method that uses a hypergraph-based data model as a unifying representation that is used in the whole visualization process: from artifacts extraction and representation, trough filtering and querying to visualization. Inspired by the knowledge representation field we propose a modified hypergraph-based representation that enhanced by incidences that are suitable to represent roles objects play in relations. We also propose a query language in which queries and query results are hypergraphs, thus making the approach transparent for visualization. The visualization of the hypergraphs representing the extracted software artifacts and their relations is based on the well known force-based graph layout algorithms. The proposed method was implemented in a software visualization prototype and verified by visualizations of an existing software project.|
