Unverified50% confidenceOpinionExact time
Cosine similarity measures semantic closeness, not factual entailment; treating cosine similarity as a guarantee of factuality is a category error.

VerifiedSemantic retrieval is based on mathematical metrics such as cosine similarity rather than simple keyword matching.80% similarUnverifiedCosine-similarity nearest-neighbor decoding is essentially a projection-style interpretation that reflects the vector's orientation in embedding space rather than the semantic content the model actually encodes or computes at that step, so it can only serve as a rough clue and cannot be treated as reasoning evidence.77% similarUnverifiedVector retrieval is based on semantic similarity rather than logical dependency relationships, and may miss critical type definitions, configuration files, or implicit coupling.70% similarVerified余弦相似度是衡量两个向量方向接近程度的指标，值域在-1到1之间，越接近1表示语义越相似70% similarUnverifiedUsing a simple text similarity threshold or difference detection can easily misclassify reasonable wording changes as violations.69% similar
