TL;DR
A maximum entropy classifier that significantly improves the accuracy of Argumentative Zoning in scientific literature and is a 23% F-score increase on the Computational Linguistics conference papers marked up by Teufel (1999).
Abstract
We present a maximum entropy classifier that significantly improves the accuracy of Argumentative Zoning in scientific literature. We examine the features used to achieve this result and experiment with Argumentative Zoning as a sequence tagging task, decoded with Viterbi using up to four previous classification decisions. The result is a 23% F-score increase on the Computational Linguistics conference papers marked up by Teufel (1999).

The semantic structure of texts can be described both at the local microlevel and at a more global macrolevel, and a model for text comprehension based on this notion accounts for the formation of a coherent semantic text base in terms of a cyclical process constrained by limitations of working memory.

The trends in the results are in agreement with those of Edmundson who used a subjectively weighted combination of features as opposed to training the feature weights using a corpus, which suggests that even shorter extracts may be useful indicative summmies.
Using Maximum Entropy for Text Classification

This paper uses maximum entropy techniques for text classification by estimating the conditional distribution of the class variable given the document by comparing accuracy to naive Bayes and showing that maximum entropy is sometimes significantly better, but also sometimes worse.
