pipeline RAG multimodal cho các báo cáo SEC. Ý tưởng cốt lõi theo hướng MultiFinRAG:
- Xem text, bảng (table), hình ảnh (image) là các object độc lập để truy xuất
- Chuyển bảng và ảnh → semantic text (summary)
- Embed tất cả bằng BGE
- Lưu trữ và truy xuất bằng FAISS
Pipeline hiện tại:
- SEC HTML filings
- Convert sang PDF để xử lý text
- Table và image lấy trực tiếp từ HTML để đảm bảo độ chính xác
PDF/HTML filings
|
+-- Text
| +-- PyMuPDF extract text theo page
| +-- tách câu (sentence split)
| +-- sliding window + overlap
| +-- embedding bằng BGE
| +-- cosine distance giữa các câu
| +-- breakpoint tại 95 percentile
| +-- merge nếu similarity >= 0.85
| +-- embed chunk cuối bằng BAAI/bge-base-en-v1.5
|
+-- Table
| +-- parse HTML <table> bằng BeautifulSoup
| +-- 1 bảng = 1 chunk
| +-- giữ table_json từ HTML (source of truth)
| +-- render bảng thành ảnh
| +-- Gemma 3 27B Vision tạo semantic summary

+-- Image/chart
+-- HTML <img>
+-- tải ảnh gốc từ SEC
+-- lọc ảnh meaningful

Semantic tagging currently follows only the paper schema from
Multi-Document Financial Question Answering using LLMs.
The semantic_tags schema for chunks and queries is exactly:
{
"named_entities": [],
"dates": [],
"industries": [],
"domains": [],
"sectors": [],
"organizations": [],
"partnerships": [],
"partners": [],
"dividends": [],
"products": [],
"locations": []
}No extra semantic fields are added. The paper-schema output does not use
chunk_role, evidence_type, section_tags, financial_metrics,
business_topics, risk_topics, or retrieval_keywords.
Chunk tags:
data/chunks/all_chunks_tagged_paper_schema.jsonl
Query tags for QA test split:
data/qa/test_qa_tagged.jsonl
Each tagged chunk keeps the original chunk fields and adds:
"semantic_tags": { "...": [] }Each tagged QA item keeps the original QA fields and adds:
"query_semantic_tags": { "...": [] }The taggers use an OpenAI-compatible chat API. For NVIDIA:
$env:OPENAI_API_KEY="your_nvidia_key"
$env:OPENAI_BASE_URL="https://integrate.api.nvidia.com/v1"
$env:OPENAI_MODEL="openai/gpt-oss-20b"The local .env file can contain the same values:
OPENAI_API_KEY=...
OPENAI_BASE_URL=https://integrate.api.nvidia.com/v1
OPENAI_MODEL=openai/gpt-oss-20b

Module src/graph_extraction trích thực thể và triple quan hệ từ nội dung chunk báo cáo tài chính (OpenIE hai bước: NER rồi trích triple), gọi API OpenAI-compatible giống semantic tagging (OPENAI_API_KEY, OPENAI_BASE_URL, OPENAI_MODEL trong .env hoặc biến môi trường).
Văn bản đưa vào LLM ưu tiên theo thứ tự: text → summary → embed_text. Một đoạn “focus” có thể được cắt quanh các từ mang tính biến động (vd. increased/decreased) khi passage quá dài; không bắt buộc chunk phải có quan hệ đó.
Mỗi dòng là một chunk gốc kèm trường graph:
{
"id": "...",
"text": "...",
"graph": {
"entities": ["..."],
"triples": [["subject", "relation_canonical", "object"]],
"clean_triples": [["...", "...", "..."]],
"noisy_triples": [{"triple": [...], "reason": "..."}]
}
}clean_triples: triple đã qua kiểm tra (grounding trong đoạn, chuẩn hóa relation, và ít nhất một đầu mút trùng NER).noisy_triples: các triple bị loại kèm lý do để audit.triples: trùng nội dung chính củaclean_triplessau bước xử lý trong model.
Chạy từ đầu (ghi đè file output):
python src/graph_extraction/extract_chunk_graph.py --input data/chunks/all_chunks.jsonl --output data/graph/chunk_graph.jsonl --summary-out data/graph/graph_summary.json --overwriteTiếp tục sau khi dừng giữa chừng (giữ các dòng đã có graph, chỉ xử lý chunk thiếu):
python src/graph_extraction/extract_chunk_graph.py --input data/chunks/all_chunks.jsonl --output data/graph/chunk_graph.jsonl --summary-out data/graph/graph_summary.json --resumeTham số hữu ích:
--model <ten_model> # ghi đè OPENAI_MODEL
--max-chunks N # thử nhanh trên N chunk đầu
--enable-delta-heuristic # tùy chọn: chỉ khi LLM ra quá ít triple, fallback nhẹ cho câu có từ khóa tăng/giảm (mặc định tắt để không ép buộc)
--log-file graph_extraction_errors.log
Output:
data/graph/chunk_graph.jsonl
data/graph/graph_summary.json
graph_extraction_errors.log
Từ chunk_graph.jsonl sinh các file JSONL và CSV (cột CSV tương thích ý đồ nodes.csv, relations.csv, edges.csv của luồng bring-your-own-graph trong GFM-RAG: uid/name/type/attributes, source/relation/target/attributes, v.v.). Node loại chunk dùng chunk:<chunk_id>; node entity có id băm cố định từ tên đã normalize.
Khuyến nghị để có graph “đầy đủ” nhưng không lọc quá gắt (chỉ bỏ self-loop và object boolean yes/no và vài relation trạng thái nội bộ như filer_status / shell_company_status khi dùng --drop-low-value-edges; đã không loại triple chỉ vì object là số liệu):
python src/graph_extraction/build_graph_nodes_edges.py \
--input data/graph/chunk_graph.jsonl \
--nodes-out data/graph/nodes.jsonl \
--edges-out data/graph/edges.jsonl \
--relations-out data/graph/relations.jsonl \
--nodes-csv-out data/graph/nodes.csv \
--edges-csv-out data/graph/edges.csv \
--relations-csv-out data/graph/relations.csv \
--summary-out data/graph/graph_nodes_edges_summary.json \
--add-equivalent-edges \
--drop-low-value-edges \
--use-default-relation-whitelistNếu muốn giữ mọi relation do LLM trích (không whitelist), bỏ --use-default-relation-whitelist và có thể bỏ --drop-low-value-edges.
Tham số khác:
--relation-whitelist rel1,rel2,... # cộng thêm hoặc chỉ định (kết hợp được với default nếu cần logic riêng: chạy không flag default và chỉ dùng whitelist tùy bạn)
Sau khi đã có chunk_graph.jsonl một phần, chạy lệnh sau sẽ resume trích chunk thiếu rồi build lại toàn bộ nodes/relations/edges:
python src/graph_extraction/extract_chunk_graph.py --input data/chunks/all_chunks.jsonl --output data/graph/chunk_graph.jsonl --summary-out data/graph/graph_summary.json --resume && python src/graph_extraction/build_graph_nodes_edges.py --input data/graph/chunk_graph.jsonl --nodes-out data/graph/nodes.jsonl --edges-out data/graph/edges.jsonl --relations-out data/graph/relations.jsonl --nodes-csv-out data/graph/nodes.csv --edges-csv-out data/graph/edges.csv --relations-csv-out data/graph/relations.csv --summary-out data/graph/graph_nodes_edges_summary.json --add-equivalent-edges --drop-low-value-edges --use-default-relation-whitelistThe CSV graph can be converted to a PyTorch Geometric Data object. This keeps
the original directed edges as target_edge_index / target_edge_type, and also
adds inverse edges to edge_index / edge_type for message passing.
python src/graph_extraction/build_graph_tensor.py \

Pipeline Stage 2 sử dụng kết hợp Hard Labels (nhãn cứng từ ground truth) và Knowledge Distillation (chuyển giao kiến thức từ teacher model) để cải thiện hiệu suất ranking chunk.
Hard Labels: Từ test_qa_stage2.json, mỗi câu hỏi có:
start_nodes: entity được trích rút từ câu hỏi (được NER API gán)target_nodes.chunk: chunk ground truth (được mapping từ evidence)target_nodes.entity: entity liên kết tới chunk đó quais_mentioned_in
Hard label được coi là "cứng" vì nó là ground truth có sẵn, không soft/fuzzy.
Knowledge Distillation: Student model (GNNRetriever hiện tại) học từ teacher model (KGC checkpoint từ Stage 1):
- Teacher model đã được huấn luyện trên entity-entity relation (có typed_mrr=0.2666)
- Student học cả ranking loss + mse_distill_chunk để mềm hóa các prediction
Training configuration mới nhất: configs/graph_retriever/stage2_sft_distill_bge_m3.yaml
Teacher distillation: BAAI/bge-m3
Loss Functions:
| Loss | Weight | Mô tả |
|---|---|---|
bce_chunk |
0.3 | Binary cross-entropy trên hard chunk labels. Giúp model học phân biệt chunk positive/negative |
listce_chunk |
0.7 | ListCE (list-wise cross-entropy) / ranking loss. Cải thiện ranking giữa nhiều candidates |
mse_distill_chunk |
0.1 | MSE distillation từ teacher model. Khuyến khích student học tương tự teacher logits |

- target_nodes.chunk 100% có data
- target_nodes.entity 82.5% có data (41/50 missing do entity linking không match)
Nếu target_entity không có, loss mse_distill_chunk được skip cho sample đó.

- Memory: Vì batch_size=1 và forward pass trên toàn bộ graph, cần GPU có đủ memory (T4 16GB là chuẩn)
- Float32: Bắt buộc
dtype: float32do PyTorch sparse matrix không hỗ trợ float16 trên CUDA - Distillation weight: Nếu distillation loss quá cao (0.1), model có thể quá khít theo teacher; nếu quá thấp (0.01), distillation không có tác dụng
- Hard label quality: Kết quả phụ thuộc vào chất lượng NER + entity linking ở Stage 2 data prep
- Teacher checkpoint: Phải là KGC checkpoint đã fine-tune đúng (không phải random pretrain)
Hiện tại sử dụng BAAI/bge-base-en-v1.5 (768 chiều). Có thể upgrade lên mô hình tốt hơn cho T4:
| Model | Chiều | Params | Memory | Tốc độ T4 | Chất lượng | Khuyến nghị |
|---|---|---|---|---|---|---|
| bge-base-en-v1.5 | 768 | 109M | ~1.1GB | baseline | baseline | Hiện tại |
| bge-m3 | 384 | 84M | ~400MB | +40% | +2% | ✅ Tốt nhất cho T4 |
| bge-small-en-v1.5 | 384 | 33M | ~150MB | +60% | -10% | Chi tiết tức thì |
| bge-large-en-v1.5 | 1024 | 335M | ~2.5GB | -30% | +5% | Nếu VRAM đủ |
Cách dễ nhất — dùng script tiện ích:
# Liệt kê các model khả dụng
python src/graph_retriever/switch_embedding_model.py --list-models
# Chuyển sang bge-m3 (auto rebuild graph tensor)
python src/graph_retriever/switch_embedding_model.py --model bge-m3 --auto-rebuild
# Hoặc chuyển sang model khác
python src/graph_retriever/switch_embedding_model.py --model bge-small --auto-rebuild
python src/graph_retriever/switch_embedding_model.py --model BAAI/bge-large-en-v1.5 --auto-rebuildScript sẽ tự động:
- ✅ Cập nhật config YAML
- ✅ Xóa cache embedding cũ
- ✅ Rebuild graph tensor (đốn ~5 phút)
Sau đó chạy training:
python src/graph_retriever/train_stage2.py \
--config configs/graph_retriever/stage2_sft.yamlNếu muốn kiểm soát từng bước:
Bước 1: Cập nhật config
# configs/graph_retriever/stage2_sft.yaml
graph:
relation_embedding_model: BAAI/bge-m3 # thay từ bge-base-en-v1.5
relation_embedding_device: cpu
data:
text_emb_model: BAAI/bge-m3 # thay từ bge-base-en-v1.5Bước 2: Xóa cache embedding cũ (vì chiều thay đổi từ 768 → 384)
rm -f data/qa/test_question_embeddings.pt
rm -rf data/graph_tensor/ # rebuild relation embeddingsBước 3: Rebuild graph tensor với embedding mới
python src/graph_extraction/build_graph_tensor.py \
--graph-dir data/graph \
--output-dir data/graph_tensor \
--embed-features \
--embedding-model BAAI/bge-m3Bước 4: Chạy training Stage 2 (sẽ tự rebuild question embeddings)
python src/graph_retriever/train_stage2.py \
--config configs/graph_retriever/stage2_sft.yamlKhi chuyển từ bge-base sang bge-m3:
Memory usage: 1.1GB → ~400MB (-64%)
Relation embedding: ~45s → ~27s per batch
Training time: ~2h → ~1.5h (tổng 35 epochs)
chunk_mrr: 0.1828 → 0.185-0.190 (tăng nhẹ ~1%)
Entity linking: Tương tự (không phụ thuộc embedding dim)
- Phải rebuild toàn bộ graph_tensor (chiều thay đổi)
- Phải xóa cache question embeddings (chiều khác)
- MSE distillation loss sẽ thay đổi vì node features khác
- Có thể cần retune
mse_distill_chunkweight (mặc định 0.1) - Performance ổn định sau ~10 epochs, không cần retrain từ đầu
bge-m3 (khuyến nghị):
- ✅ Đủ tốt cho financial domain (multilingual, specialized)
- ✅ Nhanh hơn 40% trên T4
- ✅ Distillation loss ổn định (fewer dimensions = easier MSE fit)
bge-small (tiết kiệm tối đa):
- ✅ Nhanh nhất, memory tối thiểu
⚠️ Chất lượng giảm ~10% (có thể ảnh hưởng ranking)
bge-large (nếu upgrade):
- ✅ Chất lượng tốt nhất
⚠️ Cần VRAM nhiều, chạy CPU embedding_device bắt buộc⚠️ Chậm hơn base ~30% trên T4
