We present two classifiers to classify news articles based on Labeled Latent Dirichlet Allocation, called LLDA-C and SLLDA-C.

Dealing with big data in computational social networks may require powerful machines, big storage, and high bandwidth, which may seem beyond the capacity of small labs. We demonstrate that researchers with limited resources may still be able to conduct big-data research by focusing on a specific type of data. In particular, we present a system called MPT (Microblog Processing Toolkit) for handling...
