The GraphRAG project aims to leverage implicit relationships in unstructured text to extend the range of questions that AI systems can answer on private datasets.

A key advantage of GraphRAG over traditional vector RAG (or "semantic search") is its ability to answer questions about the entire dataset. global searchFor example, "What are the major themes in the data?" or "What are the most important implications for X?" . In contrast, vectors RAG more specialized local searchThis means that the answer is similar to the query and can be found in a specific text area, usually for questions such as "who", "what", "when" and "where". where" questions.

In recent articles, two new query mechanisms are introduced that leverage the rich, digest-based data index created by GraphRAG to improve local search performance and global search cost, respectively.

In this paper, we introduce a new graph-enhanced RAG approach, LazyGraphRAG, which eliminates the need for pre-summarization of source data and avoids the upfront indexing costs that may be unaffordable for some users and use cases.

The key advantage of LazyGraphRAG is its scalability in terms of cost and quality. Among a range of competing approaches (including standard vector RAG, RAPTOR, GraphRAG local search, global search, and DRIFT search mechanisms), LazyGraphRAG excels in the cost-quality range:

LazyGraphRAG data indexing costs are the same as vector RAGs, at 0.1% of the cost of a full GraphRAG.
At a query cost comparable to that of vector RAGs, LazyGraphRAG outperforms all competing methods for localized queries, including long context vector RAGs and GraphRAG DRIFT searches (a recently introduced RAG method that outperforms vector RAGs), as well as GraphRAG localized searches.
The same LazyGraphRAG configuration also shows comparable answer quality to the GraphRAG global search in terms of global queries, but the query costsReduced by more than 700 timesThe
Query cost of searching 4% globally with GraphRAG, LazyGraphRAG on local and global query typesSignificantly outperforms all competing methodsThis includes GraphRAG global search at the C2 level (the third level of the community hierarchy recommended for most applications).

LazyGraphRAG will soon join the open source GraphRAG library to provide a unified query interface for local and global queries on lightweight data indexes at a cost comparable to standard vector RAGs.

LazyGraphRAG: Combining the Benefits of Vector RAG and GraphRAG

LazyGraphRAG aims to combine the advantages of Vector RAG and GraphRAG while overcoming their respective limitations:

The vector RAG is a Best Priority Search, which uses similarity to the query to select the most matching block of source text. However, it does not consider the breadth of the dataset for the global query.
The GraphRAG global search is a breadth-first search, it uses the community structure of the source text entities to ensure that queries are answered taking into account the complete breadth of the dataset. However, it does not consider the optimal community for localized queries.

LazyGraphRAG combines best-first and breadth-first search dynamics in an iterative deepening manner (Table 1). This approach is "inert" compared to the global search mechanism of the full GraphRAG, which delays the use of LLMs and significantly improves the efficiency of answer generation. The overall performance can be measured by one main parameter - theBudget for relevance testing- - to expand, the parameter controls the trade-off between cost and quality in a consistent manner.

LazyGraphRAG: How it works in detail

Simply put, the core idea of LazyGraphRAG is to "build on demand, check as you go".

Index construction and summarization (on demand): Instead of pre-built full indexes, LazyGraphRAG utilizes Natural Language Processing (NLP) techniques to dynamically extract key concepts and the relationships between them as queries are received. This information is then organized into a graph structure, and this graph is continuously optimized and refined as the query progresses.
Query Optimization and Content Retrieval: LazyGraphRAG utilizes techniques such as text chunk embeddings to optimize queries in real-time and pinpoint the most relevant pieces of data by analyzing associations between concepts.
Answer generation and integration: The system constructs smaller subgraphs from relevant text fragments and integrates these into answers that are coherent, accurate and match the query.

### Key Dates and Steps for Open Enrollment

The open enrollment period for 2024 health insurance plans involves several key dates and steps.

- **Marketplace Plans**: Open enrollment starts on November 1, 2023, and runs through mid-December in most states, ending on January 16, 2023. 2024 [Data: Sources (47419, 47411, 47416, 47421, 47409, +more)].

- **Medicare**: Open enrollment for Medicare runs from October 15, 2023, to December 7, 2023. During this period, individuals can choose between traditional Medicare, Medicare Advantage plans, and prescription drug plans [Data: Sources (72061, 72063, 72060, 72062)].

By considering these factors, individuals can make informed decisions about their health insurance coverage for 2024, ensuring they select plans that best meet their medical needs and financial situations.

LazyGraphRAG demonstrates that a single, flexible query mechanism has the potential to significantly outperform a variety of specialized query mechanisms in the local-global query range, without the upfront costs of LLM data summarization. Its fast and virtually free indexing makes LazyGraphRAG ideal for one-off queries, exploratory analyses, and streaming data use cases, while its ability to smoothly improve answer quality as the budget for relevance testing increases makes it an invaluable tool for benchmarking RAG methods (e.g., "RAG method X beats task Z with budget Y"). LazyGraphRAG").

Does this mean that all graph-enhanced RAGs should be inert? Not really, for three reasons:

The GraphRAG Data Index for Entity, Relationship, and Community Summaries has uses beyond Q&A (e.g., reading and sharing reports).
GraphRAG data indexing of entity, relationship, and community summaries combined with a LazyGraphRAG-like search mechanism may yield better results than LazyGraphRAG alone.
A new type of GraphRAG data indexing designed to support a search mechanism similar to LazyGraphRAG (e.g., through preemptive declarations and topic extraction) may yield the best results.

We will be exploring these directions for some time to come, and all progress (including LazyGraphRAG itself) will be made via the GraphRAG GitHub repository Posted.
