BEIJING, July 13 (Xinhua) -- The following is a summary of published science and technology news of China.

AI CANCER DETECTION

Using artificial intelligence (AI) technologies, an international research team led by Chinese scientists has developed a rapid and accurate screening model to detect lymph nodes, which can assist doctors in cancer treatment.

Based on MRI image data selected from 293 patients with rectal cancer at the Sixth Affiliated Hospital of Sun Yat-Sen University from 2013 to 2016, researchers developed the AI-assisted screening model. This turned detection experiences, accumulated by experts, into algorithms. The AI can detect the lymph nodes by a higher percentage, with only 1.37 seconds on each sample. This is 100 times faster than human detection.

NLP RESEARCH

The 58th Annual Meeting of the Association for Computational Linguistics (ACL 2020), a leading international conference on natural language processing (NLP), was held online this year due to the COVID-19 epidemic.

Chinese researchers submitted 1,170 research papers to the meeting, with 205 accepted.

Papers from Chinese researchers covered topics like the application of NLP in the legal system, how to use NLP to facilitate communication between experts and laymen, and machine reading comprehension.

SELF-DRIVING

Shanghai has announced to allow road testing of self-driving vehicles on a 30.6-km downtown open road in the city's Pudong New Area.

Shanghai had previously designated several open test roads in Jiading, Lingang and Fengxian areas in the suburbs. Enditem
