[...] * This research cluster deals with information extraction from unstructured, multimodal data, heterogeneous, complex, or dynamic data. Heterogeneity and incomplete data must be structured prior to the analysis in an homogeneous way, as most computer systems work better if multiple items are stored in an identical size and structure. But an efficient representation, access and analysis of semi-structured data is necessary because a less structured design is more useful for certain analysis and purposes.
