Information Contagion: An Empirical Study of the Spread of News on Digg and Twitter Social Networks

Kristina Lerman, R. Ghosh
Computer Science, Physics
ICWSM
12 March 2010

We extract social networks of active users on Digg and Twitter, and track how interest in news stories spreads among them. Expand

Using a model of social dynamics to predict popularity of news

Kristina Lerman, T. Hogg
Computer Science
WWW '10
26 April 2010

We show that stochastic models of user behavior on social media sites allows predicting popularity based on early user reactions to new content. Expand

MixHop: Higher-Order Graph Convolutional Architectures via Sparsified Neighborhood Mixing

Sami Abu-El-Haija, Bryan Perozzi, +5 authors A. Galstyan
Computer Science, Mathematics
ICML
30 April 2019

We propose a new model, MixHop, that can learn these relationships, including difference operators, by repeatedly mixing feature representations of neighbors at various distances. Expand

Mathematical Model of Foraging in a Group of Robots: Effect of Interference

Kristina Lerman, A. Galstyan
Computer Science
Auton. Robots
1 September 2002

We present a mathematical model of foraging in a homogeneous multi-robot system, with the goal of understanding quantitatively the effects of interference. Expand

Analysis of Dynamic Task Allocation in Multi-Robot Systems

Kristina Lerman, C. Jones, A. Galstyan, M. Mataric
Computer Science
Int. J. Robotics Res.
1 March 2006

Dynamic task allocation is a class of task allocation in which the assignment of robots to sub-tasks is a dynamic process and may need to be continuously adjusted. Expand

Social Browsing on Flickr

Kristina Lerman, L. Jones
Computer Science
ICWSM
7 December 2006

We show that social browsing through the contacts' photo streams is one of the primary methods by which users find new images on Flickr. Expand

The DARPA Twitter Bot Challenge

V. Subrahmanian, Amos Azaria, +19 authors T. Huang
Computer Science, Physics
Computer
20 January 2016

We need to identify and eliminate "influence bots" - realistic, automated identities that illicitly shape discussions on social media - before they get too influential. Expand

Electric Elves: Applying Agent Technology to Support Human Organizations

Hans Chalupsky, Y. Gil, +5 authors Milind Tambe
Computer Science
IAAI
7 August 2001

The operation of a human organization requires dozens of everyday tasks to ensure coherence in organizational activities. Expand

Wrapper Maintenance: A Machine Learning Approach

Craig A. Knoblock, Kristina Lerman, Steven N. Minton
Computer Science
J. Artif. Intell. Res.
23 June 2011

We present an efficient algorithm that learns structural information about data from positive examples alone. Expand

Automatic Data Extraction from Lists and Tables in Web Sources

Kristina Lerman, Craig A. Knoblock, Steven N. Minton, M. Rey
Computer Science
2001

We describe a technique for extracting data from lists and tables and grouping it by rows and columns by exploiting the regularities both in the format of the pages and the data contained in them. Expand
