Reuse and challenges in evaluating language generation systems
Kalina Bontcheva · 2003
Although there is an increasing shift towards evaluating Natural Language Generation (NLG) systems, there are still many NLG-specific open issues that hinder effective comparative and quantitative evaluation in this field. The paper starts off by describing a task-based, i.e., black-box evaluation of a hypertext NLG system. Then we examine the problem of glass-box, i.e., module specific, evaluation in language generation, with focus on evaluating machine learning methods for text planning.
