الكلمات الرئيسية أو استخراج مفاتيح الصوت هي تحديد الكلمات أو العبارات التي تقدم الموضوعات الرئيسية للمستند.تقترح هذه الورقة الاهتمام، وهو نموذج انتباه هجين، لتحديد الرابط القصوى من وثيقة بطريقة غير مخالفة.تعاني Natheatrank حساب اهتمام الذات والاهتمام عبر النموذج اللغوي المدرب مسبقا.تم تصميم اهتمام الذات لتحديد أهمية المرشح في سياق الجملة.يتم احتساب الاعتماد المتبادل لتحديد الأهمية الدلالية بين المرشح والجمل في وثيقة.نحن نقيم الاهتمام بثلاث مجموعات بيانات متاحة للجمهور ضد سبعة خطوط خطوط خطوط خطوط خطوط خطوط خطوط خطوط فيه.تظهر النتائج أن Natheationrank هو نموذج استخراج مفاتيح مفاتيح غير مؤظفي فعال وقوي على الوثائق الطويلة والقصيرة.يتوفر شفرة المصدر على Github.
Keyword or keyphrase extraction is to identify words or phrases presenting the main topics of a document. This paper proposes the AttentionRank, a hybrid attention model, to identify keyphrases from a document in an unsupervised manner. AttentionRank calculates self-attention and cross-attention using a pre-trained language model. The self-attention is designed to determine the importance of a candidate within the context of a sentence. The cross-attention is calculated to identify the semantic relevance between a candidate and sentences within a document. We evaluate the AttentionRank on three publicly available datasets against seven baselines. The results show that the AttentionRank is an effective and robust unsupervised keyphrase extraction model on both long and short documents. Source code is available on Github.
