🚀 Law Text2Vec
This model is used to calculate the similarity of legal texts and can be used to create vector databases, etc.
🚀 Quick Start
The Law Text2Vec model is designed for calculating the similarity of legal texts. It can be used in various legal text processing scenarios, such as building vector databases.
✨ Features
- Legal Text Similarity Calculation: Specifically designed for legal texts, it can accurately calculate the similarity between different legal statements.
- Based on Large-scale Legal Datasets: Trained on a large dataset of 936,727 national case records, ensuring the model's generalization ability.

| Whether the non - compliance of the leased house with fire safety requirements can lead to the failure to achieve the contract purpose and whether the contract is of course invalid. |
The original trial held that the two defendants, as lessees, leased a general house. Both parties were aware of the leased property, and the subject matter met the contract requirements. The leased house had problems such as insufficient fire separation distance from adjacent buildings and insufficient width of evacuation passages. The fire separation distance from adjacent buildings and the width of evacuation passages of the subject matter did not meet the national standards. After the lessees obtained the leased house for hotel operation, the fire safety requirements were increased, but it was not inevitable that the contract purpose could not be achieved, so the invalidity of the contract was not supported. The retrial held that since the leased house had been used as a service - oriented business place after its completion, the fire safety problems mentioned in this case existed to varying degrees. However, there was no record of administrative departments prohibiting its operation before. The notice from the public security fire department this time was for rectification, not for prohibiting operation. According to the "Regulations on Fire Supervision and Administration of Construction Projects" promulgated by the Ministry of Public Security in 2012, the scope of mandatory fire safety requirements applies to buildings below 50 meters. That is, the establishment of a contract relationship with the house as the leased property does not violate the mandatory provisions of the state. Referring to the relevant opinions in the reply [2003] Min Yi Ta Zi No. 11 of the Supreme People's Court on "How to Determine the Validity of a House Lease Contract Concluded without Fire Acceptance", it was determined that the lease contract signed by both parties was established and valid. |
