知识库智能化:从数据到知识的跃迁
多模态知识库自动构建
ModelEngine的知识库系统超越了传统的文档存储,实现了真正的知识理解和结构化:
# 智能知识处理管道
class IntelligentKnowledgeProcessor:
def __init__(self):
self.parser_registry = ModelEngine.MultiModalParserRegistry()
self.summary_engine = ModelEngine.HierarchicalSummaryEngine()
self.knowledge_graph_builder = ModelEngine.KnowledgeGraphBuilder()

# 多模态文档解析
parsed_content = self.parser_registry.parse(
source['content'],
content_type=source['type'],
metadata=source.get('metadata', {})
)
# 自动生成智能摘要
summaries = self.summary_engine.generate_multi_level_summary(
content=parsed_content,
levels=['executive', 'technical', 'operational'],
style=source.get('summary_style', 'professional')
)
# 构建知识图谱关系
knowledge_graph = self.knowledge_graph_builder.build_graph(
content=parsed_content,
entity_types=['product', 'feature', 'issue', 'solution'],
relation_types=['depends_on', 'solves', 'related_to']
)
processed_knowledge[source['id']] = {
'raw_content': parsed_content,
'summaries': summaries,
'knowledge_graph': knowledge_graph,
'key_entities': self._extract_key_entities(parsed_content),
'temporal_context': self._extract_temporal_context(parsed_content)
}
return self._build_unified_knowledge_base(processed_knowledge)
# 实际应用示例
