Paper Review - Event Extraction for Criminal Legal Text(Q Li, 2020)
This paper addresses issues within the realm of legal work by employing event extraction technology on the case description section of Chinese legal texts, specifically focusing on larceny cases. The authors define event types, event arguments, and their roles in larceny cases. They create a dataset for event extraction through data annotation and divide the extraction process into two stages: identifying event trigger words and jointly extracting arguments, followed by assigning event argument roles. The methodology involves utilizing BERT for Chinese character vectors, employing a BiLSTM-CRF model for initial extraction, integrating additional features, and using a CRF model for improved extraction. The extracted event data is presented in a chronological sequence to facilitate litigation visualization. The paper also discusses formatting Chinese time expressions, sorting event information chronologically, and introducing a web application for displaying the event timeline. The primary focus areas are Chinese legal text, event dataset creation, event extraction, and litigation visualization.

RAM data significance in Digital Forensics
Last semester, I made memory dump file for analyzing trace remaining after using Tor-browser. However, my boss said it is useless because that file was available to get only when the computer kept power on. After that I thought the RAM data are so volatile that forensic investigators really don’t care about when do investigation. However, today professor mentioned about RAM evidence in class, so I thought it can be important in some cases even if it has volatile properties. And then I found this paper explaining about the significance of volatile data.

The Implication of Chain of Custody to Digital Forensics Practitioners
The entire job of a digital forensic examiner is to get to the truth that the digital device under his analysis will reveal. This expertise is what the courts rely on to make conclusion on a case. The weight placed on such evidence how ever good the job done is, can be thrown away if the defence can prove a broken chain of custody. Therefore, it is imperative for a digital forensic practitioner to pay attention to how chain of custody can impact on his job.
