Application of Intelligent Information Retrieval For Big Data Oriented Brain Science

With the development of brain and cognition technology, the research on brain science is more and more thorough. And big data related to brain science is emerging. How to acquire and share these data in time is a very urgent problem in the development of brain science. Traditional information retrieval technology is often based on keyword matching, which does not investigate the semantics of retrieval words or search phrases. It has great defects in the field of brain science. And it is difficult to meet the retrieval requirements of brain science. The information retrieval about brain science has characteristics of real-time and retrieval methods diversification. So combining Ontology technology and professional needs, we proposed intelligent retrieval model based on ontology, which is suitable for the field of brain science. We improved semantic similarity algorithm more suitable for brain science information query. And the experimental results show that the retrieval of semantic similarity based on the improved algorithm can improve the recall and precision of information retrieval. Background The study of brain science become the research focus in the world. The United States, the EU, Japan have developed brain research program. New technology and new methods, new discoveries continue to emerge the brain science. In document [1],Innovation and new technology research means creation objective conditions to solve the human brain the mystery. In recent years, the theory of complex network, brain network visualization direction has achieved a breakthrough. It will play important significance for understanding the brain mechanisms and prevention of brain diseases. And it will promote the development of artificial intelligence systems. The progress of brain science is becoming more and more complex. At the same time, a large number of literature materials emerge in an endless stream. If we can index these resources in time and share them with the researchers in the most convenient way, we will greatly promote the progress of scientific research projects. Therefore, we need to design an efficient search system in the field of brain science to provide services for scientific research activities. The fundamental way to improve the quality of Brain Science information retrieval is to change disordered data into ordered knowledge, let computers understand the meaning of Brain Science information, and thus realize semantic retrieval. Research status In the field of modern brain science, information technology has become one of the ke y factors to promote the development of brain science. There are about more than 3290000 00 returned keywords in Google, including brain science, news and latest achievements. Fro m these data, we can see that at present, the information retrieval service in the field of fo 3rd International Conference on Automation, Mechanical Control and Computational Engineering (AMCCE 2018) Copyright © 2018, the Authors.
