from llama_index.vector_stores.neptune import NeptuneAnalyticsVectorStore

graph_identifier = "<YOUR_GRAPH_ID>"
embed_dim = 1536
neptune_vector_store = NeptuneAnalyticsVectorStore(
    graph_identifier=graph_identifier,
    embedding_dimension=embed_dim
)

from llama_index.core import VectorStoreIndex, SimpleDirectoryReader

documents = SimpleDirectoryReader("")  # path to your documents
documents = documents.load_data()

# Create the index
storage_context = StorageContext.from_defaults(vector_store=neptune_vector_store)
index = VectorStoreIndex.from_documents(documents, storage_context=storage_context)

Step 4: Querying the Knowledge Graph

query_engine = index.as_query_engine()
response = query_engine.query("What happened with Interleaf?")
display(response)

Use Cases for the Integration

1. Fraud Detection: Use graph techniques to monitor relationships between accounts and transactions, cross-referencing with real-time data pulled from user queries.
2. Recommendations: Build recommendation engines that utilize existing relationships in the database alongside user-input data from LlamaIndex.
3. Customer Insights: Analyze customer databases, pull insights, and predict future behaviors using LlamaIndex as a query interface integrating multiple data sources.
