HLZD Knowledge Graph

B2B 实体抽取 + 轻量内存图 + BFS 查询 + DOT 导出。

节点类型

customer / product / country / certification / hs_code / supplier

边类型

边	含义
interested_in	customer → product
sourced_from / hosted_in	customer → country
certified_by	product → certification
classified_under	product → hs_code
ordered_from	customer → supplier
complies_with	product/customer → standard

用法

from scripts import lib

text = "We need OCTG from Saudi Arabia with API 5CT and ISO 9001."
result = lib.run_pipeline(text, customer_name="Aramco",
                           query_product="OCTG",
                           query_country="Saudi Arabia")
# result["extracted_entities"] + result["graph"] + result["queries"]

Output schema

{
  "$schema": "hlzd-knowledge-graph/v1",
  "extracted_entities": {
    "products": ["OCTG", "Steel Pipe"],
    "countries": ["Saudi Arabia"],
    "certifications": ["API 5CT", "ISO 9001"]
  },
  "graph": {
    "nodes": [...],
    "edges": [...],
    "stats": {"node_count": 5, "edge_count": 6, "by_type": {...}}
  },
  "queries": {
    "related_customers_for_product": [...],
    "products_in_country": [...]
  }
}

DOT 导出

import lib
g = lib.build_graph_from_entities(entities)
dot_str = lib.export_dot(g)
# `dot -Tpng > out.png`
