Summary

How to optimize a chatbot

Leverage GPT's capabilities: Combine Elasticsearch's search relevance with OpenAI's GPT question-answering capabilities, utilizing the Chat Completion API to return to the user model-generated responses considering these top k documents as a context.

Incorporate Sentiment Analysis: Incorporate a sentiment analysis model to provide awareness of user comments and reactions as the dialog unfolds.

Observability: In addition to logs that capture chatbot interactions, it's important to track response time, latency, and other relevant chatbot metrics. By doing so, you can identify patterns, trends, and even detect anomalies.

Enhancing chatbot capabilities with NLP and vector search in Elasticsearch

In this blog, we'll explore various approaches to retrieving information using Elasticsearch, focusing on lexical and semantic search.

Prerequisites

Lexical search - sparse retrieval

String tokenization for lexical search

Lexical matching

Semantic search - dense retrieval

Semantic search with approximate kNN

Semantic search - learned sparse retrieval

Sparse vector search with Elastic Learned Sparse Encoder

Hybrid search: relevant results by combining lexical and semantic search

Elasticsearch: best of both worlds with lexical and semantic search
