Embedding Similarity
A method that encodes text as high-dimensional vectors and measures semantic relatedness between texts using metrics such as cosine similarity. It is widely applied in information retrieval, semantic search, and text classification tasks.
Timeline (last 90 days)
The contract mechanism does not rely on semantic understanding or embedding-similarity judgments, so it has almost zero latency, zero hallucination, and fully predictable behavior.
Task classification can be arranged by increasing cost and accuracy into three methods: heuristic rules, embedding similarity, and small classifier models; a pragmatic architecture is layered, with heuristic rules resolving the majority and the ambiguous remainder going to more expensive classifiers.
Embedding similarity classification decides routing by embedding the incoming prompt and performing nearest-neighbor retrieval against a vector store of past requests with labeled results; during cold start, when the store is empty or sparse, it degenerates into random routing for novel requests, so it is usually a supplement to heuristic rules rather than a replacement.
Common methods for comparing behavioral trajectories include edit distance, sequence alignment, and embedding-based similarity computation.
The embedding similarity method encodes documents and concept descriptions as high-dimensional vectors and assesses semantic closeness via metrics such as cosine similarity, relying on pretrained sentence encoders such as Sentence-BERT and text-embedding-ada-002.
