Bio: Kevin C. Chang is an Associate Professor in Computer Science, University of Illinois at Urbana-Champaign. He received a BS from National Taiwan University and PhD from Stanford University, in Electrical Engineering. His research addresses large scale information access, focusing on "entity-centric" information search, integration and mining over Web and social networks. He received a VLDB Best Papers Selection in 2000, an NSF CAREER Award in 2002, an NCSA Faculty Fellow Award in 2003, IBM Faculty Awards in 2004 and 2005, Academy for Entrepreneurial Leadership Faculty Fellow Award in 2008, and the Incomplete List of Excellent Teachers at University of Illinois in 2001, 2004, 2005, 2006, 2010, and 2011. He loves to bring research results to the real world and, with his students, co-founded Cazoodle, a startup from the University of Illinois, for deepening vertical "data-aware" search over the web. 


I lead the FORWARD Group, which is part of the larger Data and Information Systems Laboratories, at the CS department of UIUC. -

Our research interests span from Data Management to Data Mining, Information Retrieval, and Machine Learning. Our recent focus studies 1) entity-centric search and integration over text and 2) information network analysis, and 3) interactive data analytics -- across the large unstructured and structured data on the Web and social networks. As our objectives, we aim at developing novel systems, prinicpled algorithms, and formal theories that ultimately deliver real world applications. As our approaches, we try to be inspired by and learn from the data we are tackling-- in both their nature and scale-- with machine learning and data processing techniques.

Cazoodle: Search, integrate, and organize-- the real world. A UIUC startup aiming at bringing forward data-aware search, the objectives of the MetaQuerier and WISDM projects, to the world.

Current Research Projects

ARISE: Augmented Reality Information Search Engine. While the Web, as the virtual world, has information about everything in the real world, the two worlds are organized in very different orders. Can we seamlessly "mash" the two worlds-- by reorganizing the Web's "pages" into the "entities" of the real world?
WISDM: Web Indexing and Search for Data Mining. The Web has gone far beyond a corpus of pages-- it contains all sorts of "stuff", can we search the Web for every "thing" it contains? [CIDR'07, VLDB'07 , WSDM'10, EDBT'10, WWW'10, WSDM'11 (Demos: SIGMOD'07, SIGMOD'09, SIGMOD'10)
Online Demo: Entity Search (Prototype system over 500-million English pages in the ClueWeb09 corpus, for 10+ entity types, running on a 30-node PC cluster.)

Graduated Research Projects

MetaQuerier: Exploring and Integrating the Deep Web. the Web has deepened dramatically- A significant and increasing amount of information is now hidden on the "deep Web," behind the query interfaces of searchable databases, can we enable access and integrate such dynamic data? [SIGMOD'03, SIGMOD'04, KDD'04, VLDB'05, CIDR'05, KDD'05, TODS'06, CACM'07, VLDB'07, CIKM'08) (Demos: SIGMOD'04, SIGMOD'05,ICDE'05, ICDE'07
Online Demo:
AIM: Supporting Efficient Top-k Ranked Query Processing-- AIMing for top query answers. Our goal is to support ranked queries, or top-k queries, for matching data by "soft" conditions such as similarity, relevance, or preference, in order to return best k answers. [SIGMOD'02, SIGMOD'05, SIGMOD'06a, SIGMOD'06b, ICDE'07, TODS'07, TKDE'07,  SIGMOD'07a, SIGMOD'07b] (Demos:VLDB'05, SIGMOD'07)
