"# How to get a RAG application to add citations\n",
|
||
"\n",
|
||
"This guide reviews methods to get a model to cite which parts of the source documents it referenced in generating its response.\n",
|
||
"\n",
|
||
"We will cover five methods:\n",
|
||
"\n",
|
||
"1. Using tool-calling to cite document IDs;\n",
|
||
"2. Using tool-calling to cite documents IDs and provide text snippets;\n",
|
||
"3. Direct prompting;\n",
|
||
"4. Retrieval post-processing (i.e., compressing the retrieved context to make it more relevant);\n",
|
||
"5. Generation post-processing (i.e., issuing a second LLM call to annotate a generated answer with citations).\n",
|
||
"\n",
|
||
"We generally suggest using the first item of the list that works for your use-case. That is, if your model supports tool-calling, try methods 1 or 2; otherwise, or if those fail, advance down the list.\n",
|
||
"\n",
|
||
"Let's first create a simple [RAG](/docs/concepts/rag/) chain. To start we'll just retrieve from Wikipedia using the [WikipediaRetriever](https://python.langchain.com/api_reference/community/retrievers/langchain_community.retrievers.wikipedia.WikipediaRetriever.html). We will use the same [LangGraph](/docs/concepts/architecture/#langgraph) implementation from the [RAG Tutorial](/docs/tutorials/rag)."

The global cheetah population was estimated in 2021 at 6,517; it is listed as Vulnerable on the IUCN Red List. It has been widely depicted in art, literature, advertising, and animation. It was tamed in ancient Egypt and trained for hunting ungulates in the Arabian Peninsula and India.

"Another approach is to post-process our retrieved documents to compress the content, so that the source content is already minimal enough that we don't need the model to cite specific sources or spans. For example, we could break up each document into a sentence or two, embed those and keep only the most relevant ones. LangChain has some built-in components for this. Here we'll use a [RecursiveCharacterTextSplitter](https://python.langchain.com/api_reference/text_splitters/text_splitter/langchain_text_splitters.RecursiveCharacterTextSplitter.html#langchain_text_splitters.RecursiveCharacterTextSplitter), which creates chunks of a specified size by splitting on separator substrings, and an [EmbeddingsFilter](https://python.langchain.com/api_reference/langchain/retrievers/langchain.retrievers.document_compressors.embeddings_filter.EmbeddingsFilter.html#langchain.retrievers.document_compressors.embeddings_filter.EmbeddingsFilter), which keeps only the texts with the most relevant embeddings.\n",

After a gestation of nearly three months, females give birth to a litter of three or four cubs. Cheetah cubs are highly vulnerable to predation by other large carnivores. They are weaned at around four months and are independent by around 20 months of age.\\nThe cheetah is threatened by habitat loss, conflict with humans, poaching and high susceptibility to diseases. The global cheetah population was estimated in 2021 at 6,517; it is listed as Vulnerable on the IUCN Red List. It has been widely depicted in art, literature, advertising, and animation. It was tamed in ancient Egypt and trained for hunting ungulates in the Arabian Peninsula and India. It has been kept in zoos since the early 19th century.'"
