Opinion Mining and Sentiment Analysis

by Bo Pang, Lillian Lee , 2008
"... An important part of our information-gathering behavior has always been to find out what other people think. With the growing availability and popularity of opinion-rich resources such as online review sites and personal blogs, new opportunities and challenges arise as people now can, and do, active ..."

, actively use information technologies to seek out and understand the opinions of others. The sudden eruption of activity in the area of opinion mining and sentiment analysis, which deals with the computational treatment of opinion, sentiment, and subjectivity in text, has thus occurred at least in part

Data Security

by Dorothy E. Denning, Peter J. Denning , 1979
"... The rising abuse of computers and increasing threat to personal privacy through data banks have stimulated much interest m the techmcal safeguards for data. There are four kinds of safeguards, each related to but distract from the others. Access controls regulate which users may enter the system and ..."

Fab: Content-based, collaborative recommendation

by Marko Balabanovic, Yoav Shoham - Communications of the ACM , 1997
"... Fab is a recommendation system designed to help users sift through the enormous amount of information available in the World Wide Web. Operational since Dec. 1994, this system combines the content-based and collaborative methods of recommendation in a way that exploits the advantages of the two appr ..."

approaches while avoiding their shortcomings. Fab’s hybrid structure allows for automatic recognition of emergent issues relevant to various groups of users. It also enables two scaling problems, pertaining to the rising number of users and documents, to be addressed. © COPYRIGHT 1997 Association

New directions in cryptography.

by Whitfield Diffie , Martin E Hellman - IEEE Trans. Inf. Theory, , 1976
"... Abstract Two kinds of contemporary developments in cryp-communications over an insecure channel order to use cryptogtography are examined. Widening applications of teleprocess-raphy to insure privacy, however, it currently necessary for the ing have given rise to a need for new types of cryptograph ..."

The Computational Brain.

by P S Churchland , T J Sejnowski , Bruce Bridgeman , 1994
"... Keywords: reductionism, neural networks, distributed coding, Karl Pribram, computational neuroscience, receptive field 1.1 The broad goal of this book, expressed at the start, is ``to understand how neurons give rise to a mental life.'' A mental reductionism is assumed in this seductively ..."

Temperature-aware microarchitecture

by Kevin Skadron, Mircea R. Stan, Wei Huang, Sivakumar Velusamy, Karthik Sankaranarayanan, David Tarjan - In Proceedings of the 30th Annual International Symposium on Computer Architecture , 2003
"... With power density and hence cooling costs rising exponentially, processor packaging can no longer be designed for the worst case, and there is an urgent need for runtime processor-level techniques that can regulate operating temperature when the package’s capacity is exceeded. Evaluating such techn ..."

Feasibility of a Serverless Distributed File System Deployed on an Existing Set of Desktop PCs

by William J. Bolosky, John R. Douceur, David Ely, Marvin Theimer - Proc. ACM SIGMETRICS , 2000
"... We consider an architecture for a serverless distributed file system that does not assume mutual trust among the client computers. The system provides security, availability, and reliability by distributing multiple encrypted replicas of each file among the client machines. To assess the feasibility ..."

X-means: Extending K-means with Efficient Estimation of the Number of Clusters

by Dau Pelleg, Andrew Moore - In Proceedings of the 17th International Conf. on Machine Learning , 2000
"... Despite its popularity for general clustering, K-means suffers three major shortcomings; it scales poorly computationally, the number of clusters K has to be supplied by the user, and the search is prone to local minima. We propose solutions for the first two problems, and a partial remedy for the t ..."

Greedy layer-wise training of deep networks

by Yoshua Bengio, Pascal Lamblin, Dan Popovici, Hugo Larochelle , 2006
"... Complexity theory of circuits strongly suggests that deep architectures can be much more efficient (sometimes exponentially) than shallow architectures, in terms of computational elements required to represent some functions. Deep multi-layer neural networks have many levels of non-linearities allow ..."

Skill Biased Technological Change and Rising Wage Inequality: Some Problems and Puzzles

by David Card, John E. DiNardo - NATIONAL BUREAU OF ECONOMIC RESEARCH , 2002
"... The recent rise in wage inequality is usually attributed to skill-biased technical change (SBTC), associated with new computer technologies. We review the evidence for this hypothesis, focusing on the implications of SBTC for overall wage inequality and for changes in wage differentials between grou ..."
