This semantic search service is powered by a vector search enabled by large language models (LLMs). We have used an LLM embedding model to convert descriptions of each of the GLORIA sectors into vectors, or points, in a high dimensional space. When you enter a query the service converts it to vector then uses a cosine similarity metric to find the GLORIA sector nearest to the query vector.
You can visualize this process with a simple example. Imagine the words,dog, cat, and helicopter as points in a 3-D space. Because of their meaning and use, the words dog and cat will be closer together while helicopter will be further away. If you add the word puppy to the space, puppy will be located closer to dog than cat. Here we use the same idea to find the GLORIA sectors nearest in semantic similiarty to your query. This approach is called semantic search because it uses the meaning of the words, not keywords or string matching, to find the best match.
