We present the results of UMBC’s participation in the Web and Nov- elty tracks. We explored various heuristics-based link analysis approaches to the Topic Distillation task. For the novelty task we tried several methods for exploit- ing semantic information of sentences based on the SVD technique. We used SVD to expand the query and to filter redundant sentences. We also used a clus- tering algorithm that is also based on SVD.
