Abstract

A prerequisite relation describes a basic relation among concepts in cognition, education and other areas. However, as a semantic relation, it has not been well studied in computational linguistics. We investigate the problem of measuring prerequisite relations among concepts and propose a simple link-based metric, namely reference distance (RefD), that effectively models the relation by measuring how differently two concepts refer to each other. Evaluations on two datasets that include seven domains show that our single metric based method outperforms existing supervised learning based methods.

总结和评论

1. 找找作者的后续工作，或者他人的工作是否有改进
2. 尝试一下直接的方法，去掉间接引用，来度量先决关系，找到概念之间的方向
3. 可以在wikipedia是数学词条上实验，因为其本身比较严谨
