تعد دقة Coureference Event مشكلة بحثية مهمة في العديد من التطبيقات.على الرغم من النجاح الرائع الأخير للنماذج اللغوية المدربة مسبقا، فإننا نجادل بأنه لا يزال مفيدا للغاية لاستخدام الميزات الرمزية للمهمة.ومع ذلك، نظرا لأن المدخلات لتحليل Aquerence عادة ما تأتي من مكونات المنبع في خط أنابيب استخراج المعلومات، فإن الميزات الرمزية المستخرجة تلقائيا يمكن أن تكون صاخبة وأن تحتوي على أخطاء.أيضا، اعتمادا على السياق المحدد، يمكن أن تكون بعض الميزات أكثر إفادة من غيرها.بدافع من هذه الملاحظات، نقترح وحدة نمطية معتمدة على السياق على الرواية السيطرة على تدفق المعلومات من ميزات المدخلات الرمزية.جنبا إلى جنب مع طريقة تدريب صاخبة بسيطة، فإن أفضل طرازات لدينا تحقق نتائج أحدث من الفنون على مجموعة بيانات: ACE 2005 و KBP 2016.
Event coreference resolution is an important research problem with many applications. Despite the recent remarkable success of pre-trained language models, we argue that it is still highly beneficial to utilize symbolic features for the task. However, as the input for coreference resolution typically comes from upstream components in the information extraction pipeline, the automatically extracted symbolic features can be noisy and contain errors. Also, depending on the specific context, some features can be more informative than others. Motivated by these observations, we propose a novel context-dependent gated module to adaptively control the information flows from the input symbolic features. Combined with a simple noisy training method, our best models achieve state-of-the-art results on two datasets: ACE 2005 and KBP 2016.
