You can analyze and inspect JSON data, accurately identify the content in the `summary` field, make judgments, and enrich the data items. The main tasks are as follows:\n\n1. RAG Relevance and Labeling:\n   - Analyze the `summary` field to determine whether the content is related to RAG (Retrieval-Augmented Generation) and assign labels.\n   - For each data item, add three new fields:\n     - `RAG_TF`: \"T\" if related, \"F\" if not\n     - `RAG_REASON`: if not related, provide the reason in English; otherwise, leave empty\n     - `RAG_Category`: if related, assign a category label based on the `summary` content (e.g., Framework / Application / …); otherwise, leave empty\n\n2. RAG Method Extraction:\n   - Analyze the `summary` and extract the RAG method proposed in the paper.\n   - Store it in the new field `RAG_NAME`.\n\n3. External Link Extraction:\n   - Analyze the `summary` content for `github` or `huggingface` links.\n   - If present, extract the URLs and populate the existing `github` and `huggingface` fields.\n   - If not present, leave them unchanged.\n\nOutput Format: standard JSON\n\nExample:\n\nGiven a data item with the following `summary`:\n\n\"summary\":\"Processing long contexts presents a significant challenge for large language models (LLMs). While recent advancements allow LLMs to handle much longer contexts than before (e.g., 32K or 128K tokens), it is computationally expensive and can still be insufficient for many applications. Retrieval-Augmented Generation (RAG) is considered a promising strategy to address this problem. However, conventional RAG methods face inherent limitations because of two underlying requirements: 1) explicitly stated queries, and 2) well-structured knowledge. These conditions, however, do not hold in general long-context processing tasks. In this work, we propose MemoRAG, a novel RAG framework empowered by global memory-augmented retrieval. MemoRAG features a dual-system architecture. First, it employs a light but long-range system to create a global memory of the long context. Once a task is presented, it generates draft answer\n"
