عملية التحقق من المطالبة تحديا لأنها تتطلب أولا العثور على أدلة نصية ثم قم بتطبيق تستيط أدلة المطالبة للتحقق من مطالبة.تقوم Works السابقة بتقييم خطوة الاستقبال استنادا إلى الأدلة المستردة، في حين أننا نفترض أن التنبؤ الاستيباري يمكن أن يوفر إشارات مفيدة لاسترجاع الأدلة، بمعنى أنه إذا كانت الجملة تدعم مطالبة أو يجب أن تكون الجملة ذات صلة.نقترح نموذج جديد يستخدم النتيجة الاستقبال للتعبير عن الملاءمة.تجاربنا تحقق من أن الاستفادة من التنبؤ التنفيذ يحسن الترتيب قطع متعددة من الأدلة.
Claim verification is challenging because it requires first to find textual evidence and then apply claim-evidence entailment to verify a claim. Previous works evaluate the entailment step based on the retrieved evidence, whereas we hypothesize that the entailment prediction can provide useful signals for evidence retrieval, in the sense that if a sentence supports or refutes a claim, the sentence must be relevant. We propose a novel model that uses the entailment score to express the relevancy. Our experiments verify that leveraging entailment prediction improves ranking multiple pieces of evidence.
