API directive is one of the most important knowledge in API specifications. Existing approach only relies on syntactic patterns to detect API directives and lacks a deep semantic understanding. In this study, we propose a deep learning approach DeepDir to automatically detect API directives. Experimental results show that DeepDir significantly improves the state-of-the-art approach by 20.78% on average in terms of F-measure.

DeepDir：API指令检测的深度学习方法

API指令是API规范中最重要的知识之一。现有方法仅依靠语法模式来检测API指令，并且缺乏深刻的语义理解。在本研究中，我们提出了一种深度学习方法DeepDir以自动检测API指令。实验结果表明，就F测量而言，DeepDir可以将最新技术平均提高20.78％。
