Chinese internet players have flocked to a research conference on artificial intelligence here, fighting to attract students from their home country who received a top-notch education in the U.S. From a report: Chinese is the language of choice among 34 company and group booths occupying prime real estate near the entrance to the Association for the Advancement of Artificial Intelligence conference, opened Friday. Native speakers represent companies including virtual mall operator Alibaba Group Holding and Tencent Holdings, which runs the communication platform WeChat. They woo students, mainly of Chinese origin, with descriptions of comfortable jobs or invite them to attend parties. The intense competition reflects the great strides China has made in the field. This year, the AAAI received research submissions in record numbers -- at least 3,800. Entries from China increased 57% on the year to a level roughly even with those from the U.S. Moreover, Chinese researchers were involved with about 60% of the research posters on display -- a privilege given to selected papers. The research poster exhibition was sponsored by Chinese internet company Baidu.
