I have two methods to extract the table data from a semi-structured PDF and implement an RAG pipeline with langchain
*** Pandas DataFrame Agent**
*** By using MultiVectorRetriever**
I want to know :
- Is there any other method to extract tables from semi-structured pdf in langchain
- How can I get better responses when the table contains descriptive text
- When I ask a question that does not include the same words as in the table
