TLDR
Information foraging theory is an approach to understanding how strategies and technologies for information seeking, gathering and consumption are adapted to the flux of information in the environment. Expand
Want to be Retweeted? Large Scale Analytics on Factors Impacting Retweet in Twitter Network
TLDR
We found that, amongst content features, URLs and hashtags have strong relationships with retweetability. Expand
The cost structure of sensemaking
TLDR
We analyze sensemaking tasks and develop a model of the cost structure of sensemaking and its implications for user interfaces, representational tools, and information retrieval systems. Expand
The Structure of Design Problem Spaces
TLDR
It is proposed that there are important generalizations about problem solving in design activity that reach across specific disciplines. Expand
Information Foraging Theory: Adaptive Interaction with Information
Although much of the hubris and hyperbole surrounding the 1990's Internet has softened to a reasonable level, the inexorable momentum of information growth continues unabated. This wealth of… Expand
Information foraging in information access environments
TLDR
Information foraging theory is an approach to the analysis of human activities involving information access technologies that analyzes the adaptive value of information gained against the costs of performing activity in human-computer interaction tasks. Expand
A focus+context technique based on hyperbolic geometry for visualizing large hierarchies
TLDR
We present a new focus+context (fisheye) technique for visualizing and manipulating large hierarchies that assigns more display space to a portion of the hierarchy while still embedding it in the context of the entire hierarchy. Expand
Mining Longest Repeating Subsequences to Predict World Wide Web Surfing
  • J. Pitkow, P. Pirolli
  • Computer Science
  • USENIX Symposium on Internet Technologies and…
  • 11 October 1999
TLDR
Modeling and predicting user surfing paths involves tradeoffs between model complexity and predictive accuracy. Expand
Using information scent to model user information needs and actions and the Web
TLDR
This paper aims to develop predictive models capable of modeling and extracting user needs and simulating usage with respect to these needs. Expand
