英文原文

a United Nations agency says the United States, China, and Japan are leading the world in developing artificial intelligence, or AI technology. The three countries were named in a new study from the UN's World Intellectual Property Organization, or WIPO. The organization says on its website that WIPO aims to lead the development of a balanced and effective international intellectual property system.

联合国的一个机构表示，美国、中国和日本在开发人工智能（AI）技术方面处于世界领先地位。这三个国家被联合国世界知识产权组织（WIPO）发布的一项新研究点名。该组织在其网站上表示，WIPO旨在引领建立一个平衡、有效的国际知识产权体系。

The new study examines development activities in four different AI technologies worldwide. It also attempts to predict the future progression of AI as it relates to new inventions. This study is based on international patent legal findings, scientific publications, and other information. It includes patent requests in machine learning through 2016, the last year for which details are available.

这项新研究考察了全球四种不同的人工智能技术的发展活动。它还试图预测人工智能在未来与新发明相关的进展情况。本研究基于国际专利法律发现、科学出版物和其他信息。它包括了截至2016年（可获得详细信息的最后一年）的机器学习的专利申请。

Much of today's AI-related technologies are powered by machine learning. The study found that there had been as many patent applications for artificial intelligence since 2013 as there were in all the time since the term AI was first used in the 1950s.

当今许多与人工智能相关的技术都是由机器学习驱动的。研究发现，自2013年以来，人工智能的专利申请数量已经与自20世纪50年代首次使用人工智能一词以来的总数相当。
