### Constructing a knowledge graph from text
Text data often contain rich relationships and insights that can be useful for various analytics, recommendation engines, or knowledge management applications.
Diffbot's NLP API allows for the extraction of entities, relationships, and semantic meaning from unstructured text data.
By coupling Diffbot's NLP API with Neo4j, a graph database, you can create powerful, dynamic graph structures based on the information extracted from text.
These graph structures are fully queryable and can be integrated into various applications.
```python
from langchain.graphs import Neo4jGraph
from langchain_experimental.graph_transformers.diffbot import DiffbotGraphTransformer
```
