【Easy Issue/入门实战】Enhancements for the knowledge post-processing components/知识召回后置处理组件贡献

[LandJerry]

======================== English version ==============================
agentUniverse currently provides default knowledge recall post-processing component. We requires other processing component, and hope you can focus on the following directions:

Rerank: Reranking of recalls (you can refer to the Dashscope rerank component in aU).
Other post-processing component for Fusion, filtering, summarization.

You can optimize and submit the PR by combining them with specific practical application scenarios.

======================== 中文版 ==============================
agentUniverse目前提供默认的知识召回后置处理组件，项目需要其他的加工手段，期待您建设的方向如下：

• rerank：召回重排（可参考目前au接入的dashscope rerank组件）
• 融合、过滤、摘要、总结：

可结合具体场景，对于召回内容进行融合、过滤、摘要或总结，进一步提升多路召回后内容的质量
