This project is a transformer-based framework for generating dense and sparse vector embeddings of text and multimodal data. It serves as a library for fine-tuning models to perform semantic similarity tasks, retrieval, and reranking. The system is distinguished by its support for diverse architectural patterns, including bi-encoders for fast similarity search and cross-encoders for high-precision reranking. It provides dedicated pipelines for multimodal embeddings, mapping text and images into a shared vector space, and implements knowledge distillation to compress large models into smaller,
pgai is a PostgreSQL AI toolkit and framework designed to integrate large language models and vector embeddings directly into a database. It serves as a bridge for executing machine learning model requests and performing text-to-SQL translations within standard database queries. The project provides an automated vector embedding pipeline that handles the loading, parsing, and chunking of text from tables and unstructured documents. This system utilizes a background worker to synchronize embeddings automatically as source data changes and includes specialized tools for building retrieval-augme
Synonyms is a natural language processing library and semantic similarity engine specifically designed for Chinese text. It functions as a word embedding toolkit and tokenizer that extracts semantic meaning and identifies synonyms by calculating the conceptual closeness between words and sentences. The system provides a toolkit for Chinese word embedding and synonym discovery, allowing for the retrieval of semantically similar words to expand vocabulary. It distinguishes itself through a configuration-driven approach to model loading, which supports the integration of custom word embeddings t
Synonyms is a Chinese natural language processing tool focused on semantic analysis. It provides capabilities for Chinese word segmentation, part-of-speech tagging, and the retrieval of synonyms based on semantic proximity. The project converts words and sentences into numerical vector representations to calculate similarity scores. This allows for the determination of semantic proximity between different phrases and the identification of chatbot intent through sentence comparison. The system also includes tools for automated keyword extraction and importance ranking to identify significant
text2vec ist ein Text-Vektorisierungs-Toolkit und Framework für semantische Ähnlichkeit, das verwendet wird, um Wörter und Sätze in numerische Vektoren umzuwandeln. Es bietet integrierte Toolsets zur Generierung von Embeddings, zur Berechnung semantischer Nähe sowie zur Implementierung von lexikalischer und semantischer Suche.
