Abstract

In constructing a , to provide intelligent assistance for achieving more efficient, fair, and explainable trial proceedings, we propose a full-process (FITS). In the proposed FITS, we introduce essential tasks for constructing a , including information extraction, evidence classification, question generation, , , and judgment document generation. Specifically, the preliminary work involves extracting elements from legal texts to assist the judge in identifying the gist of the case efficiently. With the extracted attributes, we can justify each piece of evidence‘s validity by establishing its consistency across all evidence. During the trial process, we design an robot to assist the judge in presiding over the trial. It consists of a finite state machine representing procedural questioning and a deep learning model for generating factual questions by encoding the context of utterance in a court debate. Furthermore, FITS summarizes the controversy focuses that arise from a court debate in real time, constructed under a multi-task learning framework, and generates a summarized trial transcript in the dialogue inspectional summarization (DIS) module. To support the judge in making a decision, we adopt first-order logic to express legal knowledge and embed it in deep neural networks (DNNs) to predict judgments. Finally, we propose an attentional and counterfactual natural language generation (AC-NLG) to generate the court‘s judgment.
