Foundation for advanced RAG (#538)
So far, LangChain4j had only a simple (a.k.a., naive) RAG
implementation: a single `Retriever` was invoked on each interaction
with the LLM, and all retrieved `TextSegments` were appended to the end
of the `UserMessage`. This approach was very limiting.
This PR introduces support for much more advanced RAG use cases. The
design and mental model are inspired by [this
article](https://blog.langchain.dev/deconstructing-rag/) and [this
paper](https://arxiv.org/abs/2312.10997), making it advisable to read
the article.
This PR introduces a `RetrievalAugmentor` interface responsible for
augmenting a `UserMessage` with relevant content before sending it to
the LLM. The `RetrievalAugmentor` can be used with both `AiServices` and
`ConversationalRetrievalChain`, as well as stand-alone.
A default implementation of `RetrievalAugmentor`
(`DefaultRetrievalAugmentor`) is provided with the library and is
suggested as a good starting point. However, users are not limited to it
and can have more freedom with their own custom implementations.
`DefaultRetrievalAugmentor` decomposes the entire RAG flow into more
granular steps and base components:
- `QueryTransformer`
- `QueryRouter`
- `ContentRetriever` (the old `Retriever` is now deprecated)
- `ContentAggregator`
- `ContentInjector`
This modular design aims to separate concerns and simplify development,
testing, and evaluation. Most (if not all) currently known and proven
RAG techniques can be represented as one or multiple base components
listed above.
Here is how the decomposed RAG flow can be visualized:
This mental and software model aims to simplify the thinking, reasoning,
and implementation of advanced RAG flows.
Each base component listed above has a sensible and simple default
implementation configured in `DefaultRetrievalAugmentor` by default but
can be overridden by more sophisticated implementations (provided by the
library out-of-the-box) as well as custom ones. The list of
implementations is expected to grow over time as we discover new
techniques and implement existing proven ones.
This PR also introduces out-of-the-box support for the following proven
RAG techniques:
- Query expansion
- Query compression
- Query routing using LLM
- [Reciprocal Rank
Fusion](https://learn.microsoft.com/en-us/azure/search/hybrid-search-ranking)
- Re-ranking ([Cohere Rerank](https://docs.cohere.com/docs/reranking)
integration is coming in a [separate
PR](https://github.com/langchain4j/langchain4j/pull/539)).
