Hey @icewizardry! I'm here to assist you while you wait for a human maintainer. Let's tackle this challenge together!
To get the similarity of the question to the context and output a particular statement if the question is context-neutral, you can modify your code to check the similarity score and handle context-neutral questions accordingly. Here is an improved example of how you might do this:
from llama_index import SimpleVectorIndex, Query, SimilarityPostprocessor
# Assuming you have already created and populated your index
index = SimpleVectorIndex.load("path_to_your_index")
def query_index(question):
similarity_threshold = 0.3
similarity_top_k = 10
# Create the query engine with the SimilarityPostprocessor
query_engine = index.as_query_engine(
streaming=False,
node_postprocessors=[SimilarityPostprocessor(
similarity_cutoff=similarity_threshold, top_k=similarity_top_k)],
response_fn=custom_response_fn
)
# Query the index with the question
response = query_engine.query(question)
# Check if the question is context-neutral
if is_context_neutral(question):
return "The question is context-neutral."
# Process the response
if response:
# Check if the response contains relevant information
for res in response:
if "N/A" not in res.get('refined_response', ''):
return res['initial_response']
return "No relevant information found."
else:
return "No relevant information found."
def is_context_neutral(question):
# Implement your logic to determine if the question is context-neutral
# For example, you might check for certain keywords or patterns
neutral_keywords = ["general", "overview", "summary"]
return any(keyword in question.lower() for keyword in neutral_keywords)
# Example usage
question = "Can you give me a general overview?"
print(query_index(question))
In this improved example, the query_index
function processes the response more robustly by checking each response for relevant information and avoiding responses that indicate no relevant context (e.g., responses containing "N/A"). This ensures that the function returns the most relevant answer available [1][2].

How to get similarity_score?
Here is part of my code that queries the vector library by asking a question and returns the result to the user. How do I calculate the similarity of the question to the context, based on which I want to output a specific response?
