Computational Constancy Measures of Texts—Yule's K and Rényi's Entropy
Computational Constancy Measures Yule's K Renyi's Entropy
2015/9/16
This article presents a mathematical and empirical verification of computational constancy measures for natural language text. A constancy measure characterizes a given text by having an invariant val...
Improved Estimation of Entropy for Evaluation of Word Sense Induction
Entropy for Evaluation Word Sense Induction
2015/9/14
Information-theoretic measures are among the most standard techniques for evaluation of clustering methods including word sense induction (WSI) systems. Such measures rely on sample-based estimates of...
Enriching the Knowledge Sources Used in a Maximum Entropy Part-of-Speech Tagger
Maximum Entropy Part Speech Tagger
2015/6/12
This paper presents results for a maximumentropy-based part of speech tagger, which achieves superior performance principally by enriching the information sources used for tagging. In particular, we g...
