PoD: Positional Dependency-Based Word Embedding for Aspect Term Extraction [PDF]

Proceedings of the 28th International Conference on Computational Linguistics, 2020
يتعلم تضمين الكلمات القائم على سياق التبعية بشكل مشترك تمثيلات سياق الكلمة والتبعية، وقد ثبتت فعاليته في استخراج المصطلح الجانبي. في هذه الورقة، نقوم بتصميم تضمين الكلمات القائم على التبعية الموضعية (POD) الذي يأخذ في الاعتبار كل من سياق التبعية والسياق الموضعي لاستخراج المصطلح الجانبي. على وجه التحديد، يتم نمذجة السياق الموضعي عبر ترميز الموضع النسبي.
