Learning bayesian belief networks: an approach based on the mdl principle
Wai Lam,Fahiem Bacchus +1 more
TL;DR: A new approach for learning Bayesian belief networks from raw data is presented, based on Rissanen's minimal description length (MDL) principle, which can learn unrestricted multiply‐connected belief networks and allows for trade off accuracy and complexity in the learned model.
Proceedings ArticleDOI
MEAD - A Platform for Multidocument Multilingual Text Summarization
Dragomir R. Radev,Timothy Allison,Sasha Blair-Goldensohn,John Blitzer,Arda Çelebi,Stanko Dimitrov,Elliott F. Drabek,Ali Hakim,Wai Lam,Danyu Liu,Jahna Otterbacher,Hong Qi,Horacio Saggion,Simone Teufel,Michael Topper,Adam Winkel,Zhu Zhang +16 more
TL;DR: The functionality of MEAD is described, a comprehensive, public domain, open source, multidocument multilingual summarization environment that has been thus far downloaded by more than 500 organizations.
Proceedings ArticleDOI
Transformation Networks for Target-Oriented Sentiment Classification
TL;DR: The authors proposed a new model that employs a CNN layer to extract salient features from the transformed word representations originated from a bi-directional RNN layer, which achieved state-of-the-art performance.
Journal ArticleDOI
A multilevel approach to intelligent information filtering: model, system, and evaluation
TL;DR: A filtering model is proposed that decomposes the overall task into subsystem functionalities and highlights the need for multiple adaptation techniques to cope with uncertainties.
Proceedings ArticleDOI
Using a generalized instance set for automatic text categorization
Wai Lam,Chao Yang Ho +1 more
TL;DR: This work proposes a new technique known as the generalized instance set (GIS) algorithm by unifying the strengths of k-NN and linear classifiers and adapting to characteristics of text categorization problems.
