Document clustering aims to automatically group similar documents in one cluster using different similarity/distance measures. In this paper, we evaluate the impact of the stemming...
Assessment is an important component of learning and it also noted that many academic examination make heavy used of short answers. This assessment can be a tedious task.

Text classification categories Web documents in large collections into predefined classes based on their contents. Unfortunately, the classification process can be time-consuming and users are still required to spend considerable amount of time scanning through the classified Web documents to identify the ones that satisfy their information needs. In solving this problem, we first introduce CorSum,...
Reports generated by soldiers are common in time-critical military environments. Data fusion systems that attempt to process those reports must maintain the context for each set of observations to avoid inaccurate state estimates. This paper analyzes the selection and assignment of topical context under a Bayesian methodology. We present several techniques to decrease the hypothesis space and heuristics...
