A Configurable and Modular RAG Framework.
[ English | 中文 ]
TrustRAG is a configurable and modular Retrieval-Augmented Generation (RAG) framework designed to provide reliable input and trusted output, ensuring users can obtain high-quality and trustworthy results in retrieval-based question-answering scenarios.
The core design of TrustRAG lies in its high configurability and modularity, allowing users to flexibly adjust and optimize each component according to specific needs to meet the requirements of various application scenarios.
“Reliable input, Trusted output”
- Support for multimodal RAG question-answering, API using GLM-4V-Flash, code available at trustrag/applications/rag_multimodal.py
- TrustRAG packaging and build, supporting both pip and source installation
- Added MinerU document parsing: A one-stop open-source high-quality data extraction tool, supporting PDF/webpage/multi-format e-book extraction
[20240907]
- RAPTOR: Recursive tree retriever implementation
- Support for multiple file parsing and modularity, currently supported file types include:
text
,docx
,ppt
,excel
,html
,pdf
,md
, etc. - Optimized
DenseRetriever
, supporting index building, incremental appending, and index saving, including saving documents, vectors, and indexes - Added
ReRank
with BGE sorting, Rewriter withHyDE
- Added
Judge
with BgeJudge, determining the usefulness of articles20240711
- Create a conda environment (optional)
conda create -n trustrag python=3.9
conda activate trustrag
- Install dependencies using
pip
pip install trustrag
- Download the source code
git clone https://github.com/gomate-community/TrustRAG.git
- Install dependencies
pip install -e .

Each line in
corpus.txt
is a news paragraph. You can customize the logic for reading paragraphs. The corpus is from Large Model RAG Intelligent Question-Answering Challenge.
TextChunker
is the text chunking program, primarily using InfiniFlow/huqie as the text retrieval tokenizer, suitable for RAG scenarios.
Configuring the Retriever:
Below is a reference configuration for a hybrid retriever HybridRetriever
, where HybridRetrieverConfig
is composed of BM25RetrieverConfig
and DenseRetrieverConfig
.
# BM25 and Dense Retriever configurations
bm25_config = BM25RetrieverConfig(
method='lucene',
index_path='indexs/description_bm25.index',
k1=1.6,
b=0.7
)
bm25_config.validate()
print(bm25_config.log_config())
dense_config = DenseRetrieverConfig(
model_name_or_path=embedding_model_path,
dim=1024,
index_path='indexs/dense_cache'
)
config_info = dense_config.log_config()
print(config_info)
# Hybrid Retriever configuration
# Since the score frameworks are not on the same dimension, it is recommended to merge them
hybrid_config = HybridRetrieverConfig(
bm25_config=bm25_config,
dense_config=dense_config,
bm25_weight=0.7, # BM25 retrieval result weight
dense_weight=0.3 # Dense retrieval result weight
)
hybrid_retriever = HybridRetriever(config=hybrid_config)
Building the Index:
# Build the index
hybrid_retriever.build_from_texts(corpus)
# Save the index
hybrid_retriever.save_index()
If the index is already built, you can skip the above steps and directly load the index:
hybrid_retriever.load_index()
Retrieval Test:
query = "Alipay"
results = hybrid_retriever.retrieve(query, top_k=10)
print(len(results))
# Output results
for result in results:
print(f"Text: {result['text']}, Score: {result['score']}")
reranker_config = BgeRerankerConfig(
model_name_or_path=reranker_model_path
)
bge_reranker = BgeReranker(reranker_config)
glm4_chat = GLM4Chat(llm_model_path)
# ====================Retrieval Question-Answering=========================
test = pd.read_csv(test_path)
answers = []
for question in tqdm(test['question'], total=len(test)):
search_docs = hybrid_retriever.retrieve(question, top_k=10)
search_docs = bge_reranker.rerank(
query=question,
documents=[doc['text'] for idx, doc in enumerate(search_docs)]
)
# print(search_docs)
content = '\n'.join([f'Information[{idx}]:' + doc['text'] for idx, doc in enumerate(search_docs)])
answer = glm4_chat.chat(prompt=question, content=content)
answers.append(answer[0])
print(question)
print(answer[0])
print("************************************/n")
test['answer'] = answers
test[['answer']].to_csv(f'{PROJECT_BASE}/output/gomate_baseline.csv', index=False)
