Information networks are ubiquitous in many applications and analysis on such networks has attracted significant attention in the academic communities. One of the most important aspects of information network analysis is to measure similarity between nodes in a network. SimRank is a simple and influential measure of this kind, based on a solid theoretical(More)
The concept of dominance has recently attracted much interest in the context of skyline computation. Given an N-dimensional data set <i>S</i>, a point <i>p</i> is said to dominate <i>q</i> if <i>p</i> is better than <i>q</i> in at least one dimension and equal to or better than it in the remaining dimensions. In this paper, we propose extending the concept(More)
Recently there has been a lot of interest in graph-based analysis. One of the most important aspects of graph-based analysis is to measure similarity between nodes in a graph. SimRank is a simple and influential measure of this kind, based on a solid graph theoretical model. However, existing methods on SimRank computation suffer from two limitations: 1)(More)
There is a trend that, virtually everyone, ranging from big Web companies to traditional enterprisers to physical science researchers to social scientists, is either already experiencing or anticipating unprecedented growth in the amount of data available in their world, as well as new opportunities and great untapped value. This paper reviews big data(More)
We study the problem of question topic classification using a very large real-world Community Question Answering (CQA) dataset from Yahoo! Answers. The dataset contains 3.9M questions and these questions are organized in more than one thousand categories in a hierarchy. To our best knowledge, this is the first systematic evaluation of the performance of(More)
Neural cross talk between visceral organs may play a role in mediating inflammation and pain remote from the site of the insult. We hypothesized such a cross talk exists between the duodenum and pancreas, and further it induces pancreatitis in response to intraduodenal toxins. A dichotomous spinal innervation serving both the duodenum and pancreas was(More)
N(6)-methyladenosine (m(6)A) is the most prevalent internal modification present in mRNAs of all higher eukaryotes. With the development of MeRIP-seq technique, in-depth identification of mRNAs with m(6)A modification becomes feasible. Here we present a transcriptome-wide m(6)A modification profiling effort for rice transcriptomes of differentiated callus(More)
