A Contract Sentence Meaning Similarity Measure is a sentence meaning similarity measure between two or more contract sentences.
- Context:
- Output: Contract Sentence Similarity Score.
- It can be referenced by a Similar Contract Sentence Search System (that uses a similar contract sentence search algorithm).
- It can involve the transformation of contract-specific sentences into vectorized representations, known as embeddings, which capture the sentences' underlying meanings with a focus on legal terminology and concepts.
- It can support Contract-Related Tasks such as: contract content retrieval, contract analysis, legal document review, automated contract summarization, contractual risk assessment to identify or group sentences with similar meanings.

- Example(s):
- one based on a Contract Sentence Embedding Model.
- Contract Sentence Similarlity ("The lessee shall not sublet any portion of the premises without the lessor's prior written consent.", “Subleasing any part of the premises requires the prior written approval of the lessor.") =>
0.95
. - Contract Sentence Similarlity ("Payment shall be due within 30 days of receiving the invoice.", “The contractor must deliver the project report by the end of the month.") =>
0.53
. - Contract Sentence Similarlity ("All intellectual property rights are retained by the provider.", “This agreement shall be governed by the laws of the State of California.") =>
0.11
. - ...
- Counter-Example(s):
- A General Sentence Meaning Similarity Measure, which does not specifically account for the legal context or specialized terminology found in contracts.
- A Legal Entity Recognition System, which focuses on identifying and classifying legal entities in text rather than measuring sentence similarity.
- A Document Classification System for contracts, which categorizes entire documents rather than measuring similarity at the sentence level.

- Given two sentences, the challenge includes determining whether they express the same or very similar meaning, with a focus on applications like legal document analysis for contract management.
