In this tutorial, well explore how OpenSearch performs k-NN (k-Nearest Neighbor) search on embeddings. Each word or sentence is mapped to a high-dimensional vector space, where similar meanings cluster together. OpenSearch uses k-Nearest Neighbors (k-NN) search to find the most similar embeddings in the dataset.

For instance, for culture, we have a set of embeddings for sports, TV programs, music, books, and so on. The following image uses these embeddings to visualize how topics are clustered based on similarity and meaning. This is the k-nearest neighbor (k-NN) algorithm.

Services class Texts belonging to this class consist of explicit requests for services such as room reservations, hotel bookings, dining services, cinema information, tourism-related inquiries, and similar service-oriented requests. This doesnt imply that clusters coudnt be highly separable in higher dimensions.
