Brands can enhance customer satisfaction and gain a competitive edge by collecting, processing, and reacting to customer reviews in real time, as demonstrated in a tutorial on building a brand sentiment analysis solution for a cat food brand called "MeowMunch." This solution leverages technologies such as Redpanda, ClickHouse, and OpenAI to ingest and analyze customer feedback from various touchpoints like websites and social media. Using a Python script, reviews are streamed into Redpanda after generating vector embeddings with an OpenAI model, which are then ingested into ClickHouse for semantic queries. A Streamlit application provides a user-friendly interface for the marketing team to analyze customer sentiment by displaying popular review phrases, identifying reviews with similar sentiments, and highlighting reviews that mention specific product attributes like price. This demonstration underscores the potential of these technologies to apply to a wide range of real-time data processing tasks.
