  The School of Computer has a first-level discipline of "Computer Science and Technology", which consists of three second-level disciplines: "Computer Application Technology", "Computer Software and Theory" and "Computer Architecture". At present, three characteristic research directions of "information security", "graphics and image processing" and "digital resource management" have been condensed.


1. Information Security

The research direction of information security mainly involves research fields such as information system security evaluation, sensitive information discovery, and network public opinion analysis.


1) Information system security evaluation


Focusing on key components related to network security evaluation, such as security vulnerabilities, security management, security configuration, security policies, malicious code, and important files, carry out research on key technologies such as vulnerability discovery, evaluation model research, network security situation awareness, and exemplary security management. A series of security evaluation systems such as the host security evaluation system, network security evaluation system, enterprise network security evaluation, online network security evaluation, secret-related evaluation management system, and self-evaluation platform have been developed.


2) Sensitive information discovery


Mainly researches the collection of Internet documents and the discovery of sensitive information, the identification of host sensitive information, image pattern recognition technology, etc., developed a host document sensitive information discovery system, and achieved technological breakthroughs in the collection and storage of Internet web pages and documents.


3) Analysis of online public opinion


Focusing on the collection and storage of government online public opinion information, the classification and clustering of topics, the discovery and mining of hot topics based on sentiment computing and semantic analysis, and the backtracking and tracking of public opinion development processes, research and development of government public opinion monitoring and guidance Control platform.


2. Graphics and image processing

The research direction of graphics and image processing mainly involves research fields such as video tracking technology, image fusion technology, and medical image processing.


1) Video target detection and tracking technology


For applications such as vehicle violation monitoring and suspicious person tracking, the use of video image processing, computer vision, artificial intelligence, and pattern recognition technologies to overcome changes in lighting in the environment, changes in the appearance of targets, and noise interference in the background. The trajectory and motion parameters of the moving object in the video, such as position and scale.


2) Image fusion technology


For the fields of medicine, remote sensing, weather forecasting and military target recognition, research the technology of integrating multiple images obtained from sensors with different characteristics, different times and different resolutions into one image in the same scene, achieving pixel level, feature level and decision level Three levels of image fusion.


3) Medical image processing and analysis


In the field of medical imaging, research on medical image segmentation, medical image registration and fusion, as well as false color processing, texture analysis, three-dimensional visualization and other algorithms, to provide doctors with clearer and more accurate diagnostic information, which is conducive to the diagnosis and differential diagnosis of diseases. Improve the level of modern medical treatment.



3. Digital Resource Management

The research direction of digital resource management mainly involves research fields such as unstructured databases, electronic file management, and big data analysis and processing.


1) Unstructured database


Closely track the latest research results of TRIP database in TRIPGraph, TRIP Semantic, TRIPcof, etc., study Chinese semantic processing based on TRIP database, data mining support, vocabulary-based cross-language retrieval, etc.; study the characteristics and similarities and differences between TRIP database and NOSQL database ; Research and develop industry products based on unstructured databases.


2) Electronic file management


Focusing on the management and security control of large-scale electronic documents, carry out technical research to ensure the authenticity, integrity, reliability, and availability of electronic documents; conduct research on the Open Archive Information System (OAIS) model, and conduct long-term research on electronic documents based on OAIS. Save for technical research and system research and development; develop series of tool software and mature electronic file management products.


3) Big data analysis and processing


For the field of e-government and e-commerce, research the dynamic and heterogeneous big data analysis and mining, big data privacy and security, visualization technology under the Internet and Internet of things environment, develop big data processing technology and systems, and provide real-time or quasi-real-time data Query and analysis capabilities to meet the management needs of the government and enterprises.
