Integrating Microsoft GraphRAG into Neo4j | by Tomaz Bratanic | Jul, 2024

Microsoft’s GraphRAG implementation has gained vital consideration currently. In my final weblog put up, I mentioned how the graph is constructed and explored a number of the revolutionary features highlighted within the analysis paper. At a excessive degree, the enter to the GraphRAG library are supply paperwork containing numerous data. The paperwork are processed utilizing an Massive Language Mannequin (LLM) to extract structured details about entities showing within the paperwork together with their relationships. This extracted structured data is then used to assemble a data graph.

After the data graph has been constructed, the GraphRAG library makes use of a mixture of graph algorithms, particularly Leiden neighborhood detection algorithm, and LLM prompting to generate pure language summaries of communities of entities and relationships discovered within the data graph.

On this put up, we’ll take the output from the GraphRAG library, retailer it in Neo4j, after which arrange retrievers instantly from Neo4j utilizing LangChain and LlamaIndex orchestration frameworks.

The code and GraphRAG output are accessible on GitHub, permitting you to skip the GraphRAG extraction course of.

Dataset

The dataset featured on this weblog put up is “A Christmas Carol” by Charles Dickens, which is freely accessible through the Gutenberg Challenge.

We chosen this ebook because the supply doc as a result of it’s highlighted within the introductory documentation, permitting us to carry out the extraction effortlessly.

Graph building

Despite the fact that you’ll be able to skip the graph extraction half, we’ll discuss a few configuration choices I feel are a very powerful. For instance, graph extraction may be very token-intensive and expensive. Due to this fact, testing the extraction with a comparatively low cost however good-performing LLM like gpt-4o-mini is sensible. The fee discount from gpt-4-turbo may be vital whereas retaining good accuracy, as described on this weblog put up.

GRAPHRAG_LLM_MODEL=gpt-4o-mini

Crucial configuration is the kind of entities we need to extract. By default, organizations, individuals, occasions, and geo are extracted.

GRAPHRAG_ENTITY_EXTRACTION_ENTITY_TYPES=group,individual,occasion,geo

These default entity varieties would possibly work nicely for a ebook, however be sure to alter them accordingly to the area of the paperwork you’re looking at processing for a given use case.

One other essential configuration is the max gleanings worth. The authors recognized, and we additionally validated individually, that an LLM doesn’t extract all of the accessible data in a single extraction go.

The gleaning configuration permits the LLM to carry out a number of extraction passes. Within the above picture, we will clearly see that we extract extra data when performing a number of passes (gleanings). A number of passes are token-intensive, so a less expensive mannequin like gpt-4o-mini helps to maintain the price low.

GRAPHRAG_ENTITY_EXTRACTION_MAX_GLEANINGS=1

Moreover, the claims or covariate data shouldn’t be extracted by default. You’ll be able to allow it by setting the GRAPHRAG_CLAIM_EXTRACTION_ENABLED configuration.

GRAPHRAG_CLAIM_EXTRACTION_ENABLED=False
GRAPHRAG_CLAIM_EXTRACTION_MAX_GLEANINGS=1

It appears that evidently it’s a recurring theme that not all structured data is extracted in a single go. Therefore, we now have the gleaning configuration possibility right here as nicely.

What’s additionally fascinating, however I haven’t had time to dig deeper is the immediate tuning part. Immediate tuning is elective, however extremely inspired as it may enhance accuracy.

After the configuration has been set, we will observe the directions to run the graph extraction pipeline, which consists of the next steps.

The extraction pipeline executes all of the blue steps within the above picture. Evaluate my earlier weblog put up to be taught extra about graph building and neighborhood summarization. The output of the graph extraction pipeline of the MSFT GraphRAG library is a set of parquet information, as proven within the Operation Dulce instance.

These parquet information may be simply imported into the Neo4j graph database for downstream evaluation, visualization, and retrieval. We are able to use a free cloud Aura occasion or arrange a neighborhood Neo4j surroundings. My pal Michael Starvation did a lot of the work to import the parquet information into Neo4j. We’ll skip the import clarification on this weblog put up, nevertheless it consists of importing and establishing a data graph from 5 – 6 CSV information. If you wish to be taught extra about CSV importing, you’ll be able to examine the Neo4j Graph Academy course.

The import code is out there as a Jupyter pocket book on GitHub together with the instance GraphRAG output.

After the import is accomplished, we will open the Neo4j Browser to validate and visualize components of the imported graph.

Graph evaluation

Earlier than shifting onto retriever implementation, we’ll carry out a easy graph evaluation to familiarize ourselves with the extracted information. We begin by defining the database connection and a operate that executes a Cypher assertion (graph database question language) and outputs a Pandas DataFrame.

NEO4J_URI="bolt://localhost"
NEO4J_USERNAME="neo4j"
NEO4J_PASSWORD="password"
driver = GraphDatabase.driver(NEO4J_URI, auth=(NEO4J_USERNAME, NEO4J_PASSWORD))
def db_query(cypher: str, params: Dict[str, Any] = {}) -> pd.DataFrame:
"""Executes a Cypher assertion and returns a DataFrame"""
return driver.execute_query(
cypher, parameters_=params, result_transformer_=Consequence.to_df
)

When performing the graph extraction, we used a piece measurement of 300. Since then, the authors have modified the default chunk measurement to 1200. We are able to validate the chunk sizes utilizing the next Cypher assertion.

db_query(
"MATCH (n:__Chunk__) RETURN n.n_tokens as token_count, depend(*) AS depend"
)
# token_count depend
# 300         230
# 155         1

230 chunks have 300 tokens, whereas the final one has solely 155 tokens. Let’s now examine an instance entity and its description.

db_query(
"MATCH (n:__Entity__) RETURN n.title AS title, n.description AS description LIMIT 1"
)

Outcomes

It appears that evidently the challenge Gutenberg is described within the ebook someplace, in all probability in the beginning. We are able to observe how an outline can seize extra detailed and complex data than simply an entity title, which the MSFT GraphRAG paper launched to retain extra refined and nuanced information from textual content.

Let’s examine instance relationships as nicely.

db_query(
"MATCH ()-[n:RELATED]->() RETURN n.description AS description LIMIT 5"
)

Outcomes

The MSFT GraphRAG goes past merely extracting easy relationship varieties between entities by capturing detailed relationship descriptions. This functionality permits it to seize extra nuanced data than easy relationship varieties.

We are able to additionally look at a single neighborhood and its generated descriptions.

db_query("""
MATCH (n:__Community__) 
RETURN n.title AS title, n.abstract AS abstract, n.full_content AS full_content LIMIT 1
""")

Outcomes

A neighborhood has a title, abstract, and full content material generated utilizing an LLM. I haven’t seen if the authors use the complete context or simply the abstract throughout retrieval, however we will select between the 2. We are able to observe citations within the full_content, which level to entities and relationships from which the data got here. It’s humorous that an LLM generally trims the citations if they’re too lengthy, like within the following instance.

[Data: Entities (11, 177); Relationships (25, 159, 20, 29, +more)]

There is no such thing as a solution to increase the +extra signal, so it is a humorous means of coping with lengthy citations by an LLM.

Let’s now consider some distributions. We’ll begin by inspecting the distribution of the depend of extracted entities from textual content chunks.

entity_df = db_query(
"""
MATCH (d:__Chunk__)
RETURN depend {(d)-[:HAS_ENTITY]->()} AS entity_count
"""
)
# Plot distribution
plt.determine(figsize=(10, 6))
sns.histplot(entity_df['entity_count'], kde=True, bins=15, coloration='skyblue')
plt.axvline(entity_df['entity_count'].imply(), coloration='purple', linestyle='dashed', linewidth=1)
plt.axvline(entity_df['entity_count'].median(), coloration='inexperienced', linestyle='dashed', linewidth=1)
plt.xlabel('Entity Rely', fontsize=12)
plt.ylabel('Frequency', fontsize=12)
plt.title('Distribution of Entity Rely', fontsize=15)
plt.legend({'Imply': entity_df['entity_count'].imply(), 'Median': entity_df['entity_count'].median()})
plt.present()

Outcomes

Keep in mind, textual content chunks have 300 tokens. Due to this fact, the variety of extracted entities is comparatively small, with a mean of round three entities per textual content chunk. The extraction was accomplished with none gleanings (a single extraction go). It could be fascinating to see the distribution if we elevated the gleaning depend.

Subsequent, we’ll consider the node diploma distribution. A node diploma is the variety of relationships a node has.

degree_dist_df = db_query(
"""
MATCH (e:__Entity__)
RETURN depend {(e)-[:RELATED]-()} AS node_degree
"""
)
# Calculate imply and median
mean_degree = np.imply(degree_dist_df['node_degree'])
percentiles = np.percentile(degree_dist_df['node_degree'], [25, 50, 75, 90])
# Create a histogram with a logarithmic scale
plt.determine(figsize=(12, 6))
sns.histplot(degree_dist_df['node_degree'], bins=50, kde=False, coloration='blue')
# Use a logarithmic scale for the x-axis
plt.yscale('log')
# Including labels and title
plt.xlabel('Node Diploma')
plt.ylabel('Rely (log scale)')
plt.title('Node Diploma Distribution')
# Add imply, median, and percentile traces
plt.axvline(mean_degree, coloration='purple', linestyle='dashed', linewidth=1, label=f'Imply: {mean_degree:.2f}')
plt.axvline(percentiles[0], coloration='purple', linestyle='dashed', linewidth=1, label=f'twenty fifth Percentile: {percentiles[0]:.2f}')
plt.axvline(percentiles[1], coloration='orange', linestyle='dashed', linewidth=1, label=f'fiftieth Percentile: {percentiles[1]:.2f}')
plt.axvline(percentiles[2], coloration='yellow', linestyle='dashed', linewidth=1, label=f'seventy fifth Percentile: {percentiles[2]:.2f}')
plt.axvline(percentiles[3], coloration='brown', linestyle='dashed', linewidth=1, label=f'ninetieth Percentile: {percentiles[3]:.2f}')
# Add legend
plt.legend()
# Present the plot
plt.present()

Outcomes

Most real-world networks observe a power-law node diploma distribution, with most nodes having comparatively small levels and a few essential nodes having loads. Whereas our graph is small, the node diploma follows the facility regulation. It could be fascinating to establish which entity has 120 relationships (linked to 43% of entities).

db_query("""
MATCH (n:__Entity__) 
RETURN n.title AS title, depend{(n)-[:RELATED]-()} AS diploma
ORDER BY diploma DESC LIMIT 5""")

Outcomes

With none hesitation, we will assume that Scrooge is the ebook’s most important character. I might additionally enterprise a guess that Ebenezer Scrooge and Scrooge are literally the identical entity, however because the MSFT GraphRAG lacks an entity decision step, they weren’t merged.

It additionally exhibits that analyzing and cleansing the information is a crucial step to decreasing noise data, as Challenge Gutenberg has 13 relationships, regardless that they aren’t a part of the ebook story.

Lastly, we’ll examine the distribution of neighborhood measurement per hierarchical degree.

community_data = db_query("""
MATCH (n:__Community__)
RETURN n.degree AS degree, depend{(n)-[:IN_COMMUNITY]-()} AS members
""")
stats = community_data.groupby('degree').agg(
min_members=('members', 'min'),
max_members=('members', 'max'),
median_members=('members', 'median'),
avg_members=('members', 'imply'),
num_communities=('members', 'depend'),
total_members=('members', 'sum')
).reset_index()
# Create field plot
plt.determine(figsize=(10, 6))
sns.boxplot(x='degree', y='members', information=community_data, palette='viridis')
plt.xlabel('Degree')
plt.ylabel('Members')
# Add statistical annotations
for i in vary(stats.form[0]):
degree = stats['level'][i]
max_val = stats['max_members'][i]
textual content = (f"num: {stats['num_communities'][i]}n"
f"all_members: {stats['total_members'][i]}n"
f"min: {stats['min_members'][i]}n"
f"max: {stats['max_members'][i]}n"
f"med: {stats['median_members'][i]}n"
f"avg: {stats['avg_members'][i]:.2f}")
plt.textual content(degree, 85, textual content, horizontalalignment='heart', fontsize=9)
plt.present()

Outcomes

The Leiden algorithm recognized three ranges of communities, the place the communities on greater ranges are bigger on common. Nonetheless, there are some technical particulars that I’m not conscious of as a result of if you happen to examine the all_members depend, and you’ll see that every degree has a distinct variety of all nodes, regardless that they need to be the identical in concept. Additionally, if communities merge at greater ranges, why do we now have 19 communities on degree 0 and 22 on degree 1? The authors have accomplished some optimizations and methods right here, which I haven’t had a time to discover intimately but.

Within the final a part of this weblog put up, we’ll talk about the native and world retrievers as specified within the MSFT GraphRAG. The retrievers might be applied and built-in with LangChain and LlamaIndex.

Native retriever

The native retriever begins through the use of vector search to establish related nodes, after which collects linked data and injects it into the LLM immediate.

Whereas this diagram would possibly look advanced, it may be simply applied. We begin by figuring out related entities utilizing a vector similarity search based mostly on textual content embeddings of entity descriptions. As soon as the related entities are recognized, we will traverse to associated textual content chunks, relationships, neighborhood summaries, and so forth. The sample of utilizing vector similarity search after which traversing all through the graph can simply be applied utilizing a retrieval_query function in each LangChain and LlamaIndex.

First, we have to configure the vector index.

index_name = "entity"
db_query(
"""
CREATE VECTOR INDEX """
+ index_name
+ """ IF NOT EXISTS FOR (e:__Entity__) ON e.description_embedding
OPTIONS {indexConfig: {
`vector.dimensions`: 1536,
`vector.similarity_function`: 'cosine'
}}
"""
)

We’ll additionally calculate and retailer the neighborhood weight, which is outlined because the variety of distinct textual content chunks the entities locally seem.

db_query(
"""
MATCH (n:`__Community__`)<-[:IN_COMMUNITY]-()<-[:HAS_ENTITY]-(c)
WITH n, depend(distinct c) AS chunkCount
SET n.weight = chunkCount"""
)

The variety of candidates (textual content items, neighborhood reviews, …) from every part is configurable. Whereas the unique implementation has barely extra concerned filtering based mostly on token counts, we’ll simplify it right here. I developed the next simplified high candidate filter values based mostly on the default configuration values.

topChunks = 3
topCommunities = 3
topOutsideRels = 10
topInsideRels = 10
topEntities = 10

We are going to begin with LangChain implementation. The one factor we have to outline is the retrieval_query , which is extra concerned.

lc_retrieval_query = """
WITH gather(node) as nodes
// Entity - Textual content Unit Mapping

lc_vector = Neo4jVector.from_existing_index(
OpenAIEmbeddings(),
url=NEO4J_URI,
username=NEO4J_USERNAME,
password=NEO4J_PASSWORD,
index_name=index_name,
retrieval_query=lc_retrieval_query
)

This Cypher question performs a number of analytical operations on a set of nodes to extract and set up associated textual content information:

1. Entity-Textual content Unit Mapping: For every node, the question identifies linked textual content chunks (`__Chunk__`), aggregates them by the variety of distinct nodes related to every chunk, and orders them by frequency. The highest chunks are returned as `text_mapping`.

2. Entity-Report Mapping: For every node, the question finds the related neighborhood (`__Community__`), and returns the abstract of the top-ranked communities based mostly on rank and weight.

3. Outdoors Relationships: This part extracts descriptions of relationships (`RELATED`) the place the associated entity (`m`) shouldn’t be a part of the preliminary node set. The relationships are ranked and restricted to the highest exterior relationships.

4. Inside Relationships: Equally to exterior relationships, however this time it considers solely relationships the place each entities are throughout the preliminary set of nodes.

5. Entities Description: Merely collects descriptions of every node within the preliminary set.

Lastly, the question combines the collected information right into a structured end result comprising of chunks, reviews, inner and exterior relationships, and entity descriptions, together with a default rating and an empty metadata object. You’ve the choice to take away a number of the retrieval components to check how they have an effect on the outcomes.

And now you’ll be able to run the retriever utilizing the next code:

docs = lc_vector.similarity_search(
"What are you aware about Cratchitt household?",
okay=topEntities,
params={
"topChunks": topChunks,
"topCommunities": topCommunities,
"topOutsideRels": topOutsideRels,
"topInsideRels": topInsideRels,
},
)
# print(docs[0].page_content)

The identical retrieval sample may be applied with LlamaIndex. For LlamaIndex, we first want so as to add metadata to nodes in order that the vector index will work. If the default metadata shouldn’t be added to the related nodes, the vector index will return an error.

# https://github.com/run-llama/llama_index/blob/most important/llama-index-core/llama_index/core/vector_stores/utils.py#L32
from llama_index.core.schema import TextNode
from llama_index.core.vector_stores.utils import node_to_metadata_dict
content material = node_to_metadata_dict(TextNode(), remove_text=True, flat_metadata=False)
db_query(
"""
MATCH (e:__Entity__)
SET e += $content material""",
{"content material": content material},
)

Once more, we will use the retrieval_query function in LlamaIndex to outline the retriever. Not like with LangChain, we’ll use the f-string as a substitute of question parameters to go the highest candidate filter parameters.

retrieval_query = f"""

"""

Moreover, the return is barely totally different. We have to return the node sort and content material as metadata; in any other case, the retriever will break. Now we simply instantiate the Neo4j vector retailer and use it as a question engine.

neo4j_vector = Neo4jVectorStore(
NEO4J_USERNAME,
NEO4J_PASSWORD,
NEO4J_URI,
embed_dim,
index_name=index_name,
retrieval_query=retrieval_query,
)
loaded_index = VectorStoreIndex.from_vector_store(neo4j_vector).as_query_engine(
similarity_top_k=topEntities
)

We are able to now take a look at the GraphRAG native retriever.

response = loaded_index.question("What are you aware about Scrooge?")
print(response.response)
#print(response.source_nodes[0].textual content)
# Scrooge is an worker who's impacted by the generosity and festive spirit 
# of the Fezziwig household, notably Mr. and Mrs. Fezziwig. He's concerned 
# within the memorable Home Ball hosted by the Fezziwigs, which considerably 
# influences his life and contributes to the broader narrative of kindness 
# and neighborhood spirit.

One factor that instantly sparks to thoughts is that we will enhance the native retrieval through the use of a hybrid strategy (vector + key phrase) to search out related entities as a substitute of vector search solely.

World retriever

The world retriever structure is barely extra easy. It appears to iterate over all of the neighborhood summaries on a specified hierarchical degree, producing intermediate summaries after which producing a closing response based mostly on the intermediate summaries.

We’ve got to resolve which outline prematurely which hierarchical degree we need to iterate over, which is a not a easy choice as we do not know which one would work higher. The upper up you go the hierarchical degree, the bigger the communities get, however there are fewer of them. That is the one data we now have with out inspecting summaries manually.

Different parameters enable us to disregard communities beneath a rank or weight threshold, which we gained’t use right here. We’ll implement the worldwide retriever utilizing LangChain as use the identical map and scale back prompts as within the GraphRAG paper. Because the system prompts are very lengthy, we won’t embody them right here or the chain building. Nonetheless, all of the code is out there within the pocket book.

def global_retriever(question: str, degree: int, response_type: str = response_type) -> str:
community_data = graph.question(
"""
MATCH (c:__Community__)
WHERE c.degree = $degree
RETURN c.full_content AS output
""",
params={"degree": degree},
)
intermediate_results = []
for neighborhood in tqdm(community_data, desc="Processing communities"):
intermediate_response = map_chain.invoke(
{"query": question, "context_data": neighborhood["output"]}
)
intermediate_results.append(intermediate_response)
final_response = reduce_chain.invoke(
{
"report_data": intermediate_results,
"query": question,
"response_type": response_type,
}
)
return final_response

Let’s now take a look at it.

print(global_retriever("What's the story about?", 2))

Outcomes

The story primarily revolves round Ebenezer Scrooge, a miserly man who initially embodies a cynical outlook in the direction of life and despises Christmas. His transformation begins when he’s visited by the ghost of his deceased enterprise accomplice, Jacob Marley, adopted by the appearances of three spirits—representing Christmas Previous, Current, and But to Come. These encounters immediate Scrooge to replicate on his life and the implications of his actions, finally main him to embrace the Christmas spirit and endure vital private development [Data: Reports (32, 17, 99, 86, +more)].

### The Position of Jacob Marley and the Spirits

Jacob Marley’s ghost serves as a supernatural catalyst, warning Scrooge in regards to the forthcoming visitations from the three spirits. Every spirit guides Scrooge by means of a journey of self-discovery, illustrating the affect of his decisions and the significance of compassion. The spirits divulge to Scrooge how his actions have affected not solely his personal life but additionally the lives of others, notably highlighting the themes of redemption and interconnectedness [Data: Reports (86, 17, 99, +more)].

### Scrooge’s Relationships and Transformation

Scrooge’s relationship with the Cratchit household, particularly Bob Cratchit and his son Tiny Tim, is pivotal to his transformation. Via the visions introduced by the spirits, Scrooge develops empathy, which conjures up him to take tangible actions that enhance the Cratchit household’s circumstances. The narrative emphasizes that particular person actions can have a profound affect on society, as Scrooge’s newfound generosity fosters compassion and social duty inside his neighborhood [Data: Reports (25, 158, 159, +more)].

### Themes of Redemption and Hope

Total, the story is a timeless image of hope, underscoring themes comparable to empathy, introspection, and the potential for private change. Scrooge’s journey from a lonely miser to a benevolent determine illustrates that it’s by no means too late to alter; small acts of kindness can result in vital optimistic results on people and the broader neighborhood [Data: Reports (32, 102, 126, 148, 158, 159, +more)].

In abstract, the story encapsulates the transformative energy of Christmas and the significance of human connections, making it a poignant narrative about redemption and the affect one particular person can have on others throughout the vacation season.

The response is sort of lengthy and exhaustive because it suits a world retriever that iterates over all of the communities on a specified degree. You’ll be able to take a look at how the response adjustments if you happen to change the neighborhood hierarchical degree.

Abstract

On this weblog put up we demonstrated the best way to combine Microsoft’s GraphRAG into Neo4j and implement retrievers utilizing LangChain and LlamaIndex. This could means that you can combine GraphRAG with different retrievers or brokers seamlessly. The native retriever combines vector similarity search with graph traversal, whereas the worldwide retriever iterates over neighborhood summaries to generate complete responses. This implementation showcases the facility of mixing structured data graphs with language fashions for enhanced data retrieval and query answering. It’s essential to notice that there’s room for personalization and experimentation with such a data graph, which we’ll look into within the subsequent weblog put up.

As all the time, the code is out there on GitHub.
