About
similarities is a comprehensive, open-source toolkit designed for advanced similarity calculation and semantic search. Built with Python 3, it offers out-of-the-box functionality for various tasks, including text-to-text, text-to-image, and image-to-image searches, capable of handling billion-level datasets. The toolkit features semantic matching models based on text2vec for text similarity and search, supporting multiple SentenceBERT-like pre-trained models across various languages. It also includes literal matching models like Word2Vec and BM25. For image and cross-modal similarity, similarities leverages CLIP models, enabling image-to-image, text-to-image, and vector-to-image searches with support for Chinese-CLIP models and GPU acceleration. It provides command-line tools for vector extraction, index building, batch retrieval, and service deployment, making it a versatile solution for developers and data scientists.
