 - Синтаксический анализ языков программирования: в компиляторах, интерпертаторах, средах разработки, других инстументах.
 - Анализ естественных языков. Активность в этой области несколько спала, так как на передний план сейчас вышли различные методы машинного обучения.
-  Однако и в этой области ведуться работы.Например, [International Conference on Parsing Technologies](http://www.wikicfp.com/cfp/program?id=1853).
