Definition
The Altlex dataset consists of pairs of sentences that share the same underlying meaning but utilize different vocabulary or syntactic structures. It is primarily utilized in training embedding models to ensure that semantically similar sentences are mapped to close vector representations, even when surface-level lexical overlap is minimal. This enhances the robustness of natural language understanding systems in handling paraphrases and synonyms effectively.
Summary
