Social influence is ubiquitous in cultural markets, from book recommendations in Amazon, to song popularities in iTunes and the ranking of newspaper articles in the online edition of the New York Times to mention only a few. Yet social influence is often presented in a bad light, often because it supposedly increases market unpredictability. Here we study a model of trial-offer markets, in whic...

Over 20 years ago, in 1989, The New York Times published a very similar article, also citing studies demonstrating the connection between exercise and lifespan. ( http://www.nytimes.com /1989/11/03/us/exercise-and-longevity-a-little-goes-a-long-way.html ) The study did not elaborate on what health aspects exercise improved, just that the mortality rate was 3 times higher in the least fit category.

We introduce period names, a new approach for quantitative and qualitative temporal representation and reasoning of resources in the Semantic Web. Our work has been implemented into the Bremen University Semantic Translator for Enhanced Retrieval (BUSTER). This enables us to perform a query of the form concept@location in time. Motivation and requirements An important part of search in the Web ...

The Pentagon intended to employ a "virtual stock market" — for the aggregation of information and derivation of forecasts — to help predict foreign-policy events such as a coup d'état in a particular country or terrorist atta...

This paper studies crossword puzzles as a vehicle for analyzing information in a rigorous yet meaningful fashion. The paper asks, how does information operate in the context of crossword puzzles? A model is proposed that quantifies the difficulty of a puzzle P with respect to its clues. Given a clue-answer pair (c, a), we model the difficulty of guessing a based on c using the conditional proba...

This paper presents a method for constructing a specific type of language resources that are conveniently applicable to analysis of trending topics in time-annotated textual data. More specifically, the method consists of building a co-occurrence network from the on-line content (such as New York Times articles) that conform to key words selected by users (e.g., ’Arab Spring’). Within the netwo...
