Mining Unstructured Big Text: A Multi-Dimensional Analysis Approach

The real-world big data are largely unstructured, interconnected, and dynamic, in the form of natural language text. It is highly desirable to transform such massive unstructured data into structured knowledge. Many researchers rely on labor-intensive labeling and curation to extract knowledge from such data.   However, such approaches may not be scalable, especially considering that a lot of text corpora are highly dynamic and domain-specific.  On the other hand, massive text data itself may disclose a large body of hidden patterns, structures, and knowledge.   Equipped with domain-independent and domain-dependent knowledge-bases, we should explore the power of massive data itself for turning unstructured data into structured knowledge.  By organizing massive text documents into multidimensional text cubes, structured knowledge can be extracted and used effectively.

In this talk, we introduce a set of methods developed recently in our group for such an exploration, including mining quality phrases, entity recognition and typing, multi-faceted taxonomy construction, and construction and exploration of multi-dimensional text cubes.   We show that data-driven approach could be a promising direction at transforming massive text data into structured knowledge.



Jiawei Han is Abel Bliss Professor in the Department of Computer Science, University of Illinois at Urbana-Champaign.   He has been researching into data mining, information network analysis, database systems, and data warehousing, with over 900 journal and conference publications. He has chaired or served on many program committees of international conferences in most data mining and database conferences.  He also served as the founding Editor-In-Chief of ACM Transactions on Knowledge Discovery from Data and the Director of Information Network Academic Research Center supported by U.S. Army Research Lab (2009-2016), and is the co-Director of KnowEnG, an NIH funded Center of Excellence in Big Data Computing since 2014.  He is Fellow of ACM, Fellow of IEEE, and received 2004 ACM SIGKDD Innovations Award, 2005 IEEE Computer Society Technical Achievement Award, and 2009 M. Wallace McDowell Award from IEEE Computer Society.  His co-authored book "Data Mining: Concepts and Techniques" has been adopted as a textbook popularly worldwide.
