To retrieve the previous and next nodes of a node obtained using QueryFusionRetriever without using RetrieverQueryEngine and PrevNextNodePostprocessor, you can directly use the get_forward_nodes and get_backward_nodes functions. Here is how you can do it: def retrieve_prev_next_nodes(node_with...
(1)登录链接,创建一个新的 Search Engine https://programmablesearchengine.google.com/ (2)创建完后,Search engine ID 即为所需的 CSE ID。 (3)配置 CSE ID 到你的代码中:将这个 CSE ID 放到你的程序 .env 文件中作为环境变量加载。 GOOGLE_CSE_ID = "xxxxxxx" 0.3 安装依赖Python包 我的安装以下两...
KnowledgeGraphRAGRetriever实际上是一个检索器对象,将问题或任务作为输入,对知识图谱执行子图谱 RAG 的检索,将检索结果(节点)返回,作为下游的LLM或者query engine使用。 KnowledgeGraphRAGRetriever的工作原理如下: 从用户自然语言的查询字符串中获取实体。 从图存储中以知识序列(Knowledge Sequence)的形式获取子图谱(Subgra...
* Meta Searching: The scope of each search engine is limited and no search engine has the database that covers all the web pages. This problem was noted long ago and was solved with the help of Meta search sites that make use of multiple search engines to search for the "Query String....

The data set discovery engine comprises a data set indexer configured to generate similarity indexes for a plurality of data sets, and a relativistic retriever coupled to the data set indexer and configured to obtain a suitability template for a query and to execute the query against one or ...
The engine instance uses the DataConnection to query the database based on the rule conditions, and any rows returned by the query would be asserted into the engine's working memory as TypedDataRows. Reasserting the DataConnection ensures that rows from a previous execution of the engine are ...
The system searching module uses a retriever and re-ranker engine that first finds the closest neighbors to the query embedding and then sifts the results through a cross-encoder model that identifies the most relevant documents. The ... D Silva,F Bao 被引量: 0发表: 2022年 A Framework for...
