The Laboratory for Computational Content Analysis (LCCA) at the Institute for Computing in the Humanities, Arts, and Social Science and National Center for Supercomputing Applications on the University of Illinois campus is dedicated to the application of computational methods to the analysis of vast archives of textual content in the service of deriving new understanding of data at scales previously impossible.
In particular, the Laboratory brings together a core of highly interdisciplinary expertise, leveraging disciplines from geography and journalism to psychology and linguistics unified with a deep background in computational methods and high performance computing to tackle the "grand challenge" problems that define the new era of "big data" research.
Laboratory research spans the range of computational content analysis approaches, from digitization and digital content acquisition (including scanning and OCR), to vocabulary analysis, textually referenced spatial and temporal analysis, topic analysis, natural language processing, automatic categorization and clustering, sentiment and valiance analysis, and network analysis. We work with a wide range of data sources, from declassified global news archives to social media, thematic digital libraries, corporate data archives, and just about any other large source of data.
A key focal point of the Laboratory's research is on the application of these techniques at scale, adapting and evolving the state of the art to exploit the hundred-million-page archives emerging from the global digital revolution, leveraging the large-memory supercomputing resources of the NSF's Teragrid and producing fundamentally new understandings.
