The growth of social media provides a convenient communication scheme for people, but at the same time it becomes a hotbed of misinformation. The wide spread of misinformation over social media is injurious to public interest. We design a framework, which integrates collective intelligence and machine intelligence, to help identify misinformation. The basic idea is: (1) automatically index the ...

chronology of extinction roughly coincided with major climatic changes that occurred during the Pleistocene – Holocene transition and also with the fi rst arrival of humans into the South American continent (Koch and Barnosky 2006). However, recent work that synthesizes information from many investigators suggests somewhat diff erent extinction chronologies in diff erent eco-regions of the cont...

Search log sessions contain a large number of paraphrases contributed by users during query rewriting. However, it is a big challenge to distinguish paraphrases from the simply related queries in the sessions. This paper addresses this problem by making innovative use of user behavior information embodied in query sessions. Specifically, we learn paraphrase patterns from the search log sessions...

In this paper, we propose a time-line based framework for topic summarization in Twitter. We summarize topics by sub-topics along time line to fully capture rapid topic evolution in Twitter. Specifically, we rank and select salient and diversified tweets as a summary of each sub-topic. We have observed that ranking tweets is significantly different from ranking sentences in traditional extracti...

The electrophoretic mobility of oil droplets, dispersed without any surfactant in the aqueous phase, was measured. Four different oils were studied: xylene, dodecane, hexadecane, and perfluoromethyldecalin. Special precautions were undertaken to avoid artifacts caused by the presence of surfactant impurities. The results show that the oil droplets are negatively charged and the magnitude of the...

Cellular data and communication networks are usually modeled as graphs with each node representing a base station in a cell in the network, and edges representing geographical adjacency of cells. The problem of channel assignment in such networks can be seen as a graph multicoloring problem. We survey the models, algorithms, and lower bounds for this problem. — 1.1 INTRODUCTION In a cellular ne...
