PLDA model was used to identify topic contained in the NSF project data in the field of artificial intelligence from 2013 to 2018. The funding time, funding amount and centrality indexes of the topic were taken as three indexes to judge research front topics. Threshold value was set according to Pareto Law. And 17 research front topics in the artificial intelligence field were determined. The results showed that 13 aspects, including intelligent system and intelligent community, quantum technology, molecular programming, intelligent simulation, underwater communication and positioning, big data analysis and so on, are the main research front contents concerned in the field of artificial intelligence in the United State. co-word analysis, probability theme mode, etc. The effect of probability theme model is preferably [2]. In 2017, Zhang lei et al [1] used text analysis and tech- mining methods to analyze the National Science Foundation (NSF)fund projects data, and illustrates Graphene will impact the evolution of the main research fields and research hot- spots. Based on the Top50 subject words obtained, the emerging indicators were used to explore the technical hot- spots and future research directions in the Graphene field. In 2017, Wang wenjuan et al. [3] found a new way based on LDA to detect subjects of projects and their articles to grasp topic distribution and evolution of funding agency and found the topics of projects. In 2017, Wang xiaoyue et al. [4] used PLDA model to identify the theme in the fund project data of carbon nano-tubes. And they detected the research front topics based on the subsidy time of topics, the amount of subsidies and the center of the index. At the same time, the visual analysis method of topic evolution is used to analyze the evolution of research topics and predict the development trend. In 2018, Xu lu et al. [5] proposed a new scientific research fronts detecting method to fund sponsored projects based on the TDT (Topic Detection and Tracking) model. The paper analyzes the funding intensity, time dimension, topic dimension, and other attributes of fund projects, constructed the indexes of scientific research front detection to identify hot-spots front topics, emerging front topics and future front topics. As the same time, the competitive situation of scientific research fronts was revealed. In 2018, Li jing et al. [6] proposed a method of forecasting and visualizing the emerging topics of fund sponsored projects based on time series analysis and SVM model. They constructed the emerging topics detection formula, and use deep learning algorithms model to predict and analyze the development trend of new topics. Moreover, visual analysis software Gephi is applied to visualize and reveal the competitive trend in Graphene field.

I NTRODUCTION The change and development of science and technology is the result of long-term accumulation of basic research. The National Science Foundation (NSF), founded in 1950, has been playing an important role in basic scientific research in United States and even the whole world. Professor Subra Suresh, President of the NSF, said in his tenure summary in 2013:In more than 60 years, 70% of the researchers who won the Nobel Prize were related to NSF fund sponsored projects [1]. That means more than 200 winners whose research have been funded by NSF. Therefore, investigating the information contained in the text of the NSF found projects will help us know well the research front earlier and faster. Recently, many scholars have carried out fruitful theoretical exploration and empirical studies about detecting research front based on found projects information. Commonly methods used are mainly burst word detection, 978-1-7281-4691-1/19/$31.00 ©2019 IEEE DOI 10.1109/AIAM48774.2019.00023 In recent years, artificial intelligence has developed rapidly and achieved remarkable results.
