With `QAnything`, you can simply drop any locally stored file of any format and receive accurate, fast, and reliable answers. Currently supported formats include: **PDF(pdf)**,**Word(docx)**,**PPT(pptx)**,**XLS(xlsx)**,**Markdown(md)**,**Email(eml)**,**TXT(txt)**,**Image(jpg，jpeg，png)**,**CSV(csv)**,**Web links(html)** and more formats coming soon… ## Key features - **Data Security**, supports installation and usage with network cable unplugged throughout the process. - **Cross-language QA support**, freely switch between Chinese and English QA, regardless of the language of the document. - **Supports massive data QA**, two-stage retrieval ranking, solving the degradation problem of large-scale data retrieval; the more data, the better the performance. - **High-performance production-grade system**, directly deployable for enterprise applications. - **User-friendly**, no need for cumbersome configurations, one-click installation and deployment, ready to use. - **Multi knowledge base QA** Support selecting multiple knowledge bases for Q&A ## Architecture

### Why 2 stage retrieval? In scenarios with a large volume of knowledge base data, the advantages of a two-stage approach are very clear. If only a first-stage embedding retrieval is used, there will be a problem of retrieval degradation as the data volume increases, as indicated by the green line in the following graph. However, after the second-stage reranking, there can be a stable increase in accuracy, **the more data, the better the performance**.
two stage retrievaal
QAnything uses the retrieval component [BCEmbedding](https://github.com/netease-youdao/BCEmbedding), which is distinguished for its bilingual and crosslingual proficiency. BCEmbedding excels in bridging Chinese and English linguistic gaps, which achieves - **A high performance on Semantic Representation Evaluations in MTEB**; - **A new benchmark in the realm of RAG Evaluations in LlamaIndex**. ### 1st Retrieval（embedding） | Model | Retrieval | STS | PairClassification | Classification | Reranking | Clustering | Avg | |:-------------------------------|:--------:|:--------:|:--------:|:--------:|:--------:|:--------:|:--------:| | bge-base-en-v1.5 | 37.14 | 55.06 | 75.45 | 59.73 | 43.05 | 37.74 | 47.20 | | bge-base-zh-v1.5 | 47.60 | 63.72 | 77.40 | 63.38 | 54.85 | 32.56 | 53.60 | | bge-large-en-v1.5 | 37.15 | 54.09 | 75.00 | 59.24 | 42.68 | 37.32 | 46.82 | | bge-large-zh-v1.5 | 47.54 | 64.73 | **79.14** | 64.19 | 55.88 | 33.26 | 54.21 | | jina-embeddings-v2-base-en | 31.58 | 54.28 | 74.84 | 58.42 | 41.16 | 34.67 | 44.29 | | m3e-base | 46.29 | 63.93 | 71.84 | 64.08 | 52.38 | 37.84 | 53.54 | | m3e-large | 34.85 | 59.74 | 67.69 | 60.07 | 48.99 | 31.62 | 46.78 | | ***bce-embedding-base_v1*** | **57.60** | **65.73** | 74.96 | **69.00** | **57.29** | **38.95** | ***59.43*** | - More evaluation details please check [Embedding Models Evaluation Summary](https://github.com/netease-youdao/BCEmbedding/blob/master/Docs/EvaluationSummary/embedding_eval_summary.md)。 ### 2nd Retrieval（rerank） | Model | Reranking | Avg | |:-------------------------------|:--------:|:--------:| | bge-reranker-base | 57.78 | 57.78 | | bge-reranker-large | 59.69 | 59.69 | | ***bce-reranker-base_v1*** | **60.06** | ***60.06*** | - More evaluation details please check [Reranker Models Evaluation Summary](https://github.com/netease-youdao/BCEmbedding/blob/master/Docs/EvaluationSummary/reranker_eval_summary.md) ### RAG Evaluations in LlamaIndex（embedding and rerank） ***NOTE:*** - In `WithoutReranker` setting, our `bce-embedding-base_v1` outperforms all the other embedding models. - With fixing the embedding model, our `bce-reranker-base_v1` achieves the best performance. - **The combination of `bce-embedding-base_v1` and `bce-reranker-base_v1` is SOTA**. - If you want to use embedding and rerank separately, please refer to [BCEmbedding](https://github.com/netease-youdao/BCEmbedding) ### LLM The open source version of QAnything is based on QwenLM and has been fine-tuned on a large number of professional question-answering datasets.
