Big Data Processing: Big Challenges and Opportunities

With the rapid growth of emerging applications like social network, semantic web, sensor networks and LBS (Location Based Service) applications, a variety of data to be processed continues to witness a quick increase. Effective management and processing of large-scale data poses an interesting but critical challenge. Recently, big data has attracted a lot of attention from academia, industry as...

Opinion: Big data biomedicine offers big higher education opportunities.

I like to tell my students a story about a time back in the “olden days” of the early 1990s when I was a newly minted postdoctoral fellow at the National Institutes of Health (NIH). Our laboratory conducted brain imaging studies using positron emission tomographic imaging and would routinely obtain 6–12 functional image volumes per subject in our experiments. The director of our neuroimaging la...

Challenges and Opportunities with Big Data

Heterogeneity, scale, timeliness, complexity, and privacy problems with Big Data impede progress at all phases of the pipeline that can create value from data. The problems start right away during data acquisition, when the data tsunami requires us to make decisions, currently in an ad hoc manner, about what data to keep and what to discard, and how to store what we keep reliably with the right...

Opportunities in Big Data Management and Processing

Every day we witness new forms of data in various formats. Some example include structured data from transactions we make, unstructured data as text communications of different kinds, varieties of multimedia files and video streams. To ensure efficient processing of this data, often called ‘Big Data’, the use of highly distributed and scalable systems and new data management architectures, e.g....
