Query: Knowledge Graph and Accurate Portrait Construction of Scientific and
  Technological Academic Conferences   In recent years, with the continuous progress of science and technology, the
number of scientific research achievements is increasing day by day, as the
exchange platform and medium of scientific research achievements, the
scientific and technological academic conferences have become more and more
abundant. The convening of scientific and technological academic conferences
will bring large number of academic papers, researchers, research institutions
and other data, and the massive data brings difficulties for researchers to
obtain valuable information. Therefore, it is of great significance to use deep
learning technology to mine the core information in the data of scientific and
technological academic conferences, and to realize a knowledge graph and
accurate portrait system of scientific and technological academic conferences,
so that researchers can obtain scientific research information faster.
