Legal research is a vital part of the work of lawyers. the increasing complexity of legal cases has led to a desire for fast and accurate legal information retrieval, leveraging semantic information. However, two main problems occur on that path. First, the share of published judgments is only marginal. Second, it lacks state-of-the-art NLP approaches to extract semantic information. the latter, in turn, can be attributed to the issue of data scarcity. One big issue in the publication process of court rulings is the lack of automatization. Yet, the digitalization of court rulings, specifically transforming the textual representation from the court into a machine-readable format, is mainly done manually. To address this issue, we propose an automated pipeline to segment court rulings and extract metadata. We integrate that pipeline into a prototypical web application and use it for a qualitative evaluation. the results show that the extraction of metadata and the classification of paragraphs into the respective verdict segments perform well and can be utilized within the existing processes at legal publishers.

In this paper, a wideband 1-bit dual-polarized unit cell has been presented at Ku-band. It comprises three substrates and four metallic layers. the proposed structure uses polarization conversion technique, and out of phase characteristic of electric field in patch dominant mode to get two phase states. Using this characteristic provides the proposed structure with considerable bandwidth and accurate phase difference between two states. Two PIN diodes are used as switches for two phase states. Activating one diode for each state results in the conversion of x-polarized to y-polarized (and vice versa) incident wave with a 180 ° phase difference between the two states. Notably, only one control voltage suffices for both diodes, simplifying the design of the control system. the proposed structure has been simulated using CST software. Numerical results show good matching and 180 ° ±2 ° phase difference between two states from 11.2 GHz -14.2 GHz with 25 % relative bandwidth. the proposed structure can be used for different beamforming, beam steering and RIS applications.
