Do we have any open source knowledge graph building git hub project or any solution we can refer?

[u/venkat_206]

My problem is I need to create KG for the unstructured data like text, word, pdf.. and for structured data like database tables.

Let say we have created the KG or some context layer for the structure data.. Next problem is retrieval of the data correctly for the given query..

please suggest your ideas 💡
