Adding Relationships to the SEC Knowledge Graph

Creating Form 10K nodes

• Each of the chunks has the information that we need to create the form node.
• 

Adding relationships to the graph

• Goal: Add relationships to improve the context around each chunk.
• 
• We can create linked list of all chunks belonging to a section.
• Another relationship: Connecting the form to the first chunk of each section.
  • This will enable to easily navigate from the form to the beginning of a particular section.

Notebook

• Jupyter Notebook
• Observation:
  • Default retrieval is from a single chunk. For window query, context is expanded with adjacent chunks.
  • This is reflected in the answer to the query on Netapp's ransomware protection. Window query expands the context by mentioning NetApp's ONTAP data management software.
