Automatically Generating Wikipedia Articles: A Structure-Aware Approach

In this paper, we investigate an approach for creating a comprehensive textual overview of a subject composed of information drawn from the Internet. We use the high-level structure of human-authored texts to automatically induce a domain-specific template for the topic structure of a new overview. The algorithmic innovation of our work is a method to learn topic-specific extractors for content selection jointly for the entire template. We augment the standard perceptron algorithm with a global integer linear programming formulation to optimize both local fit of information into each topic and global coherence across the entire overview. The results of our evaluation confirm the benefits of incorporating structural information into the content selection process.National Science Foundation (U.S.) (grant IIS-0448168)National Science Foundation (U.S.) (grant IIS-0835445)National Science Foundation (U.S.) (grant IIS- 0835652)National Institutes of Health (U.S) ( grant V54LM008748
