Query: Research on Cross-media Science and Technology Information Data
  Retrieval   Since the era of big data, the Internet has been flooded with all kinds of
information. Browsing information through the Internet has become an integral
part of people's daily life. Unlike the news data and social data in the
Internet, the cross-media technology information data has different
characteristics. This data has become an important basis for researchers and
scholars to track the current hot spots and explore the future direction of
technology development. As the volume of science and technology information
data becomes richer, the traditional science and technology information
retrieval system, which only supports unimodal data retrieval and uses outdated
data keyword matching model, can no longer meet the daily retrieval needs of
science and technology scholars. Therefore, in view of the above research
background, it is of profound practical significance to study the cross-media
science and technology information data retrieval system based on deep semantic
features, which is in line with the development trend of domestic and
international technologies.
