This article discusses the implementation of semantic search using PostgreSQL and OpenAI Embeddings. It explains how word embeddings capture semantic relationships between words and demonstrates how to utilize text-embedding-ada model and cosine similarity for sorting reviews. The article also covers the use of vector databases, specifically the open-source PostgreSQL extension pgvector, for storing and searching embeddings. The potential applications of semantic search extend beyond text data to other forms of data such as sound, video, and images.
Implementing Semantic Search with PostgreSQL and OpenAI Embeddings
Implementing semantic search within corporate databases can be challenging, but it doesn’t have to be. In this article, we show you how to use PostgreSQL and OpenAI Embeddings to implement semantic search on your data. We also provide links to free embedding models if you prefer not to use OpenAI Embeddings API.
What are Word Embeddings?
Word embeddings are dense vector representations of words in a vector space. They capture semantic relationships between words, allowing for semantic search on available data.
Using OpenAI’s Text-Embedding-Ada Model
We can use OpenAI’s text-embedding-ada model to generate embeddings. The choice of distance function doesn’t matter much, but cosine similarity is recommended by OpenAI.
Storing Embeddings in a Database
Once a word or document is transformed into an embedding, it can be stored in a database. However, the database needs to support fast operations on the vector to be considered a vector database.
Using pgvector with PostgreSQL
We can use pgvector, an open-source PostgreSQL extension, to enable vector similarity search functionalities. The article provides instructions on how to run PostgreSQL with pgvector and demonstrates how to create a table, insert embeddings, and select similar items.
The Potential Applications
Implementing semantic search with PostgreSQL and OpenAI Embeddings has vast applications. It can be used for corporate searches, medical record systems, and similarity calculations for various types of data such as sound, video, and images.
