Speech Title: Towards User-centric Information Seeking in the Intelligent Era
Abstract: One of the fundamental problems in information science has become even more critical in intelligent era: how to identify objects satisfying a user’s information need. The goal is to present to the user only information that is of personalized interests, in an interactive and interpretable way. Unfortunately, to this goal, current information seeking techniques are still far from being as satisfied as expected. User’s information need is often complex and vague and most information services perform the seeing process mainly replying on relevance matching. In this talk, I will first highlight the key characteristics and challenges of information seeking in the intelligent era, and then introduce recent progresses made in my team at Renmin University of China. Specifically, I will introduce our research work on personalized search, interactive search, and explainable recommendation. Finally, I will discuss some directions for future research.
Speech Title: Big Data, Semantics, Their Relationships, and Their Methodologies
Abstract: Big data analysis has been booming for a several years and various methodologies have been proposed to the solutions to big data analysis. Its purpose is to discover patterns of bid data, reveal new relationships/links among the big data, and thus predict what will happen in the future. At moment such big data analysis is beset by the “pure” data analysis methods without human being’s strong involvement and interference. An example in this direction is machine translation – learning to translate from massive translation instances. However, profound understanding of data, their relationships, and sematic discovery depend on the acquisition, understanding, and representation of concepts (the connotation of data), whereas the values of the data can be considered to be the extension. Various relationships among concepts, such as part-whole, internal-external, inter-layers, and “material-element” are a few typical semantic relationships that describe better the characteristics of big data and hence provide an innovative view toward big data analysis. This talk intends to open up a door to semantic analysis of big data as well as connections from data to concepts

Speech title: Key technologies of stock forecasting models based on big data and crowd intelligence
Abstract: Along with the economic development, an increasing number of factors and high-order data have considerably influenced the fluctuations in stock market. Many existing studies have considered the spatio-temporal correlation of stock index but ignored the comprehensive influence of crowd intelligence on stock index with changes in time and space. Therefore, to improve the forecasting accuracy of the multi-factor and high-order time series stock forecasting models, some key technologies based on big data and crowd intelligence are explored, by combining knowledge graph, crowd sensing, semantic search, personalized recommendation, game theory, fuzzy time series, credit scoring, deep learning, etc. The experimental results demonstrate that the proposed model shows outstanding forecasting accuracy compared with the benchmark methods on the Shanghai Stock Exchange Composite Index and Taiwan Stock Exchange Capitalization Weighted Stock Index.

Speech Title: The Gesture Recognition Driven by Big Data
Abstract: Gesture recognition has attracted great attention owing to its applications in many fields such as Human Computer Interaction. In recent years, the development of deep learning has promoted approaches of gestures recognition. However, the performance of deep learning techniques depends on the quantity and quality of training data. In other words, the big data plays a significant role in the deep learning-based gesture recognition.
This talk will share our experience on Large-scale video-based Gesture Recognition with an effective 3D CNN based method. To use the big data to drive the gesture recognition, we first employ different modalities of data, including RGB, depth, saliency, and optical flow, and enhance them according their different characters. Then we leverage the 3D CNN to extract spatiotemporal features blended together in the next stage to boost the performance. Finally the classes are predicted with a linear SVM classifier. Our proposed method ranked the 1st place in two rounds of the Chalearn LAP Large-scale Gesture Recognition Challenge in 2016 and 2017.

Speech title: Deep Data Analysis in Healthcare
Abstract: Nowadays, with the rapid development of the medical industry, the application of big data technology in the medical industry has also brought tremendous opportunities. Big data in healthcare have the following characteristics: multi-source, heterogeneous, polysemy and low quality. This report introduces many challenges and difficulties we met during our work, such as multi-heterogeneous data fusion, inconsistent medical concepts and so on. In order to solve these difficulties, we have made great efforts, and made great progress in our research work. Our research works can divided into seven aspects: fusion of big data in whole life cycle healthcare, big data in healthcare modeling and store base on big graph, quality assessment for big data in healthcare, construction of health map, medical concept representation learning and disease risk prediction, quality monitoring for medical services, clinical pathway pattern mining, etc. Making good use of these achievements will be of great value to medical diagnosis, decision aids, patient monitoring and government management.
