Hey @LarFii , would you have a roadmap of when node2vec will be utilised in LightRAG, also additionally, would this have huge improvement over the querying stage of RAG?
经过代码分析,我发现虽然系统中声明了 node_embedding_algorithm=node2vec 作为节点嵌入算法,但实际运行中并未调用 _node2vec_embed 进行嵌入计算。在进行 entity、relationship 和 text units 的召回时,系统仅仅使用了图数据库最基础的 get_node、get_edge 等 graph 操作来查询直接关系,这种使用方式完全可以用普通的关系型数据库来实现。那么,使用 graph 的主要目的是否仅仅局限于数据存储和计算 degree 用于排序?值得注意的是,目前的实现并未充分发挥 graph 在处理多级间接关系方面的优势,比如无法实现从 A 经过 B、C 最终到达 D 这样的间接关系路径发现。
