SCOPE:
Intelligent pre/post-processing plays a crucial role in knowledge discovery from big data. Counting of words, compression/decompression of row data, and segmentation of time series, etc. are those concrete examples and are embedded in many important applications. However, such a task becomes a critical part when processing whole data along with an increase of the data size. For this problem, many researchers have proposed novel data structures, algorithms, and frameworks for data use. Besides, we need a new approach for handling dynamic data streams and reconstructing veracious knowledge. Graph structures including string, tree, bipartite- and di-graph are a promising notion for the above problem. So, as the focus of this workshop, we call any idea for realizing big data integration, including but not limited to developing algorithm or data structure with theoretical/experimental results, introducing a framework for feature extraction, and learning, mining and modeling with big data in the real world. A survey of this field is also welcome.

KEYWORDS (not limited to):
Algorithms and data structures for strings/trees/graphs, information extraction, community extraction, and knowledge discovery from graphs, pattern mining algorithms, data compression, stream algorithms for time series, structured learning, graphical models, combinatorial optimization in machine learning/data mining, and their applications.
