Accurate Argumentative Zoning with Maximum Entropy models
نویسندگان
چکیده
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). Finally, we demonstrate the performance of our system in different scientific domains by applying it to a corpus of Astronomy journal articles annotated using a modified Argumentative Zoning scheme.

Robust Argumentative Zoning for Sensemaking in Scholarly Documents
We present an automated approach to classify sentences of scholarly work with respect to their rhetorical function. While previous work that achieves this task of argumentative zoning requires richly annotated input, our approach is robust to noise and can process raw text. Even in cases where the input has noise (as is obtained from optical character recognition or text extraction from PDF fil...
متن کاملAssessment of Artificial Neural Network Models and Maximum Entropy in Zoning of Gully Erosion Sensitivity of Golestan Dam Basin
Zoning of gully erosion susceptibility and determining the factors controlling gully erosion is very important and vital. The aim of this study was to investigate the spatial distribution of gully erosion using two models of ANN and MaxEnt and to determine the factors affecting this type of erosion in Golestan Dam basin. Therefore, 14 factors in the form of three divisions, including topographi...
متن کاملAutomatic Critiquing of Novices’ Scientific Writing Using Argumentative Zoning
Scientific writing can be hard for novice writers, even in their own language. We present a system that applies Argumentative Zoning (AZ) (Teufel & Moens 2002), a method of determining argumentative structure in texts, to the task of advising novice writers on their writing. We address this task by automatically determining the rhetorical/argumentative status and the implicit author stance of a...
متن کاملAutomatic Argumentative-Zoning Using Word2vec
In comparison with document summarization on the articles from social media and newswire, argumentative zoning (AZ) is an important task in scientific paper analysis. Traditional methodology to carry on this task relies on feature engineering from different levels. In this paper, three models of generating sentence vectors for the task of sentence classification were explored and compared. The ...
متن کاملZoning Design for Handwritten Numeral Recognition
In the field of Optical Character Recognition (OCR), zoning is used to extract topological information from patterns. In this paper zoning is considered as the result of an optimisation problem and a new technique is presented for automatic zoning. More precisely, local analysis of feature distribution based on Shannon’s entropy estimation is performed to determine “core” zones of patterns. An ...
