Sentence-BERT

Summary. Automation of database indexing is a crucial component of modern database management systems that enhances search performance, scalability, and relevance in large-scale data environments. This paper explores the application of deep learning algorithms for building and optimizing vector indexes capable of automatic adaptation to changes in data structure and query patterns. An experimental comparison was conducted between traditional indexing methods (B-Tree, GIN in PostgreSQL) and vector-based indexing using Sentence-BERT embeddings implemented in FAISS and Milvus systems.

This article presents a comprehensive approach to sentiment analysis in social networks by leveraging modern text processing methods and machine learning algorithms. The primary focus is the integration of the Sentence-BERT model for text vectorization and XGBoost for sentiment classification. Using the Sentiment140 dataset, an extensive study of text messages labeled with sentiment annotations was conducted. The Sentence-BERT model enables the generation of high-quality vector representations of textual data, preserving both lexical and contextual relationships between words.
