Figure 4
The figure shows nine circles, and at the top, the title reads “2013 to 2018.” Each circle has nodes in it, and all the nodes inside the circles are marked with an inverted triangle. All the nodes are densely connected to each other with lines. The largest circle in the middle is labeled “Robotics Thermodynamics Computer Science, Software Engineering.” The second largest circle is on the top right of the largest circle and is labeled “Radiology, Nuclear Medicine and Medical Imaging Geography, Physical Information Science and Library Science.” The largest node is in the largest circle labeled “BAIDU” with dense connection with other nodes of the circle. Some of the nodes in these two circles are as follows: “tencent ai,” “suny buffalo,” “univ kentucky,” “northwestern polytech univ,” “carnegie mellon univ,” “macau univ sci and technol,” “cornell univ,” “rutgers state un,” “peking univ,” “huawei noahs ark labnankai univ,” “rutgers state,” “dalian univ technol,” “calif los angeles,” “shanghai nao tong univ,” “univ sydney,” “beihang univ,” “natl univ singapore,” “univ oxford,” “xi an jiao tong univ,” “chinese acad sci,” and so on. On the bottom right, two medium-sized circles are present labeled “Chemistry, Analytical Instruments and Instrumentation Computer Science, Information Systems,” and “Engineering, Aerospace Telecommunications Computer Science, Information Systems.” Some nodes in these two circles are as follows: “univ sci and technol,” “south china univ technol,” “technol and applicat,” “nanjing unis,” “univ chinese acad sci,” “hong kong univ sci and technol,” “shenzhen univ,” “fudan univ,” “chinese ctr dis control and prevent.” At the bottom, a small blue circle is present labeled “Psychology, Experimental Psychology, Multidisciplinary Mechanics,” and the nodes are as follows: “nanyang technol univ,” “mit univ hong kong,” “hunan univ.” The small rectangle at the bottom left is labeled “Education, Scientific Disciplines Chemistry, Multidisciplinary Biochemistry and Molecular Biology.” The nodes in this circle are as follows: “beijing univ posts,” “missouri univ sci and technol,” “univ elect.” At the top left, a small blue circle is shown labeled “Computer Science, Software Engineering Telecommunications Engineering, Electrical and Electronic.” The only one node is as follows: “univ cent.” At the top, another small circle is shown labeled “Multidisciplinary Sciences.” The nodes are as follows: “univ maryland,” “jilin univ.” At the top, another circle is shown labeled “Business Engineering, Multidisciplinary ManagementL.” The nodes are as follows: “jiaotong univ,” “renmin univ china,” “xidian univ,” “technol beijing co ltd.”Baidu’s co-publication network from 2013 to 2018.
