UnverifiedA study proposes that differences between representational similarity metrics are far less important than the differences introduced by the objects of comparison (i.e., how data is organized).80% similarUnverifiedFunctions such as knowledge base retrieval and semantic search are essentially comparisons of similarity between vectors.77% similarUnverifiedThe core of vector search is semantic similarity, which cannot distinguish hard differences along business dimensions such as year.74% similarUnverifiedThe problem of distinguishing 'different terminology but equivalent meaning' from 'similar terminology but different substance' is referred to as semantic equivalence judgment in the field of information retrieval.72% similarUnverifiedContext relevance is related to but not identical to recall and precision in the information retrieval field: recall measures whether the documents needed for the answer were retrieved, precision measures how many of the retrieved documents are relevant, while context relevance is closer to an overall judgment of whether the retrieval results as a whole are sufficient to answer the user's question.72% similar
