Cost-effective outbreak detection in networks
TLDR
This work exploits submodularity to develop an efficient algorithm that scales to large problems, achieving near optimal placements, while being 700 times faster than a simple greedy algorithm and achieving speedups and savings in storage of several orders of magnitude. Expand
The political blogosphere and the 2004 U.S. election: divided they blog
TLDR
Differences in the behavior of liberal and conservative blogs are found, with conservative blogs linking to each other more frequently and in a denser pattern. Expand
Spotting fake reviewer groups in consumer reviews
TLDR
This paper studies spam detection in the collaborative setting, i.e., to discover fake reviewer groups by using several behavioral models derived from the collusion phenomenon among fake reviewers and relation models based on the relationships among groups, individual reviewers, and products they reviewed to detectfake reviewer groups. Expand
What Yelp Fake Review Filter Might Be Doing?
TLDR
This work attempts to find out what Yelp might be doing by analyzing its filtered reviews and postulates that Yelp’s filtering is reasonable and its filtering algorithm seems to be correlated with abnormal spamming behaviors. Expand
Evolutionary games and computer simulations.

  • 30 July 1993
TLDR
It is shown that the results of digital simulations regarding territoriality and cooperation differ greatly when time is discrete as opposed to continuous, which casts doubt on the implications of cellular automata-type simulations for the study of cooperation in social systems. Expand
Cascading Behavior in Large Blog Graphs
TLDR
Some surprising findings of the blog linking and information propagation structure are reported, after one of the largest available datasets, with 45,000 blogs and ~ 2.2 million blog-postings is analyzed. Expand
Patterns of Cascading Behavior in Large Blog Graphs
TLDR
Some surprising findings of the blog linking and information propagation structure are reported, after one of the largest available datasets, with 45, 000 blogs and ≈ 2.2 million blog-postings is analyzed. Expand
Leave a Reply: An Analysis of Weblog Comments
TLDR
A large-scale study of weblog comments and their relation to the posts is presented, using a sizable corpus of comments to estimate the overall volume of comments in the blogosphere; analyze the relation between the weblog popularity and commenting patterns in it; and measure the contribution of comment content to various aspects of weblogs access. Expand
Predicting Movie Sales from Blogger Sentiment
  • G. Mishne, N. Glance
  • Computer Science
  • AAAI Spring Symposium: Computational Approaches…
  • 2006
TLDR
The main finding is that positive sentiment is indeed a better predictor for movie success when applied to a limited context around references to the movie in weblogs, posted prior to its release. Expand
Fake Review Detection : Classification and Analysis of Real and Pseudo Reviews
TLDR
A novel and principled method is proposed to discover the precise difference between the two types of review data using the information theoretic measure KL-divergence and its asymmetric property and reveals some very interesting psycholinguistic phenomena about forced and natural fake reviewers.
