تركز طرق تعلم الجهاز لتحليل المستندات المالية بشكل رئيسي على الجزء النصي.ومع ذلك، فإن الأجزاء العددية من هذه المستندات غنية أيضا بمحتوى المعلومات.من أجل تحسين تحليل النص المالي، يجب علينا أن نحقق المعلومات الرقمية في العمق.في ضوء ذلك، فإن الغرض من هذا البحث هو تحديد الارتباط بين CASCTAG المستهدف والأرقام المستهدفة في التغريدات المالية، التي تعد أكثر تحديا من تحليل الأخبار والوثائق الرسمية.في هذا البحث، قمنا بتطوير نهج خلط متعدد النماذج يدمج تمثيلات تشفير ثنائية الاتجاه من المحولات (بيرت) والشبكة العصبية التنافعية (CNN).نحن أيضا ترميز معلومات التبعية خلف النص إلى النموذج لاستخلاص الميزات الكامنة الدلالية.تظهر النتائج التجريبية أن نموذجنا يمكنه تحقيق أداء رائع ومقارنات تفوق.
Machine learning methods for financial document analysis have been focusing mainly on the textual part. However, the numerical parts of these documents are also rich in information content. In order to further analyze the financial text, we should assay the numeric information in depth. In light of this, the purpose of this research is to identify the linking between the target cashtag and the target numeral in financial tweets, which is more challenging than analyzing news and official documents. In this research, we developed a multi model fusion approach which integrates Bidirectional Encoder Representations from Transformers (BERT) and Convolutional Neural Network (CNN). We also encode dependency information behind text into the model to derive semantic latent features. The experimental results show that our model can achieve remarkable performance and outperform comparisons.
