livelihoods, how to deal with its negative impacts, and which mitigation or adaptation policies to support. A line of related work has used bag of words and word-level features to detect frames automatically in text. Such works face limitations since standard keyword based features may not generalize well to accommodate surface
retrieval are challenges under the consideration of the aggregation of medical data is so large that it has to be stored in a cloud server. This paper proposes the similarity search tree structure to enhance the hit rate of multi-keyword ranking search. We also propose dynamic interval clustering algorithm DIK-MEDOIDS under
single machine. Our motivating application is recommenders, which typically deal with big numbers of users and items, but other applications might benefit as well, like keyword search. In this paper, we propose a parallel top-k MapReduce algorithm that, unlike existing MapReduce solutions, manages to handle cases in which
Mining big data often requires tremendous computational resources. This has become a major obstacle to broad applications of big data analytics. Cloud computing allows data scientists to access computational resources on-demand for building their big data analytics solutions in the cloud. However, the monetary cost of mining big data in the cloud can still be unexpectedly high. For example, running...
microposts of delegates selected from each similar community. Selecting delegates can reduce the processing time of large amounts of redundant data during topic detection. Obtaining public opinion keywords in real time allows organizations to respond to public opinion security incidents in real time. Experiments showed that our
