Data and its relationship with Machine Learning and Artificial Intelligence algorithms, is increasingly dominating the research landscape, as intelligent applications become embedded in our daily lives. My research in techniques that extract, transform and integrate data using graph based approaches, is central to this relationship. People and machines can benefit from these techniques applied to knowledge graphs or linked data or semantic web, for purposes such as data integration, knowledge discovery and in-depth analyses.
