Probabilistic Plan Inference for Group Behavior Prediction
Found in: IEEE Intelligent Systems
By Wenji Mao,Jonathan Gratch,Xiaochen Li
Issue Date:July 2012
pp. 27-36
A probabilistic plan inference approach explicitly takes an observed agent's preferences into consideration and computes expected plan utilities to disambiguate competing hypotheses.
 
From Causal Scenarios to Social Causality: An Attributional Approach
Found in: IEEE Intelligent Systems
By Wenji Mao,Ansheng Ge,Xiaochen Li
Issue Date:November 2011
pp. 48-57
Inspired by the psychological attribution theory, this article presents a computational approach to construct causal scenarios and facilitate social causality studies based on online textual data.
 
Test Method for Stability Time of Electromagnetic Relay Used in Aerospace
Found in: Pervasive Computing, Signal Porcessing and Applications, International Conference on
By Li Xiaochen, Li Bing, Zhai Guofu
Issue Date:September 2010
pp. 846-850
Time parameters of electromagnetic relay used in aerospace such as the bound time, the arcing time, the over-travel time and the stability time can effectively describe the contact reliability. So these parameters should be carefully measured and checked b...
 
Comparison and Analysis Between Holt Exponential Smoothing and Brown Exponential Smoothing Used for Freight Turnover Forecasts
Found in: 2013 Third International Conference on Intelligent System Design and Engineering Applications (ISDEA)
By Xiaochen Li
Issue Date:January 2013
pp. 453-456
Nowadays, most of the of transportation demand forecast are using Brown exponential smoothing which is a kind of the time series prediction methods. But in practical situation, Brown exponential smoothing is greatly influenced by data, when the data is ina...

In order to promote Chinese language learning and improve the architecture of Chinese learning website to provide a better user experience, we analyze the web usage of a Chinese learning website using power law cumulative probability statistics for the fir...
 
Searching XML Documents by Keywords in Structured P2P Networks
Found in: Database and Expert Systems Applications, International Workshop on
By Xiaochen Li, Toshiyuki Amagasa, Hiroyuki Kitagawa
Issue Date:September 2008
pp. 274-278
In this paper we present a scheme for searching XML documents by keywords in DHT-based structured P2P networks. Our idea is to construct an inverted index for XML documents in an DHT-based P2P network. To this end, we discuss how to decompose XML documents...
 
Ad-hoc distributed spatial joins on mobile devices
Found in: Parallel and Distributed Processing Symposium, International
By P. Kalnis,N. Mamoulis,S. Bakiras, Xiaochen Li
Issue Date:April 2006
pp. 9
PDAs, cellular phones and other mobile devices are now capable of supporting complex data manipulation operations. Here, we focus on ad-hoc spatial joins of datasets residing in multiple non-cooperative servers. Assuming that there is no mediator available...
