Contracts need to be reviewed to be verified if they include all the essential clauses for them to be valid. Such clauses are highly formal and repetitive regardless of the kinds of contracts, and automated legal technologies are required for legal text comprehension. In this paper, we have constructed a simple item-by-item classification model for clauses in contracts to estimate contract eligibility by addressing formal and repetitive properties of contract clauses. We have used keyword embeddings based on conventional requirements of contracts and concatenate them to sentence embeddings of clauses, extracted from a BERT model fine-tuned with legal documents. The contract eligibility can be verified by the predicted labels. Based on our methods, we report reasonable performances with the accuracy of 90.57 and 90.64, and an F1-score of 93.27 and 93.26, using additional keyword embeddings with BERT embeddings.

Due to the exponential growth of mobile data and the densification of base stations, it is necessary to newly install various types of transport networks such as fronthaul, mid-haul, and backhaul, to enhance mobile communication networks. However, as the existing wired line based solution was not profitable for mobile communication operators in proportion to data volume growth, there is a need of a new concept and technology that can support flexible deployment of radio access network and enhance the cost efficiency of mobile communication carriers. In this paper, we design a network architecture and a transmission scheme for xHaul link as a unified wireless transport solution for MXN(Mobile xHaul Network) that can improve the installation flexibility and the network mobility with mobile multi-hop relay technology. Then we evaluate the performance of xhaul link in various deployment scenarios through system level simulator. As the results of performance evaluation, we verify that xHaul can provide up to 20Gbps capacity and that MXN can meet the performance requirements of 5G mobile service.
