In current education, it is difficult for a teacher to know the engagement of each student, the contents that students cannot understand and the reason why students cannot perform sufficiently in the quizzes and exams. To study student engagement in classroom, we digitize materials used in lectures, including textbooks and collect event logs of tablets used by students. By analyzing these logs, we...
In this study, build interactive location database intelligent video car recorder system. Video automotive logger system was established in the iOS intelligent mobile devices (iPhone). The video car recorder system can be record the current driving conditions, display the current location on the map, and upload it to the location database. Location database is constructed by a network server, MySQL,...
Most of the existing academic social networks like DBLP and ArnetMiner suggest co-authors as being related to each author based on author and co-author details, which are extracted from academic researchers publications. Instead of this approach, we propose grouping of researchers on basis of topics they have in common that would make more semantic sense for a user searching for publications in an...
This paper contains analysis and simulation of recent dynamic models, describing human emotion. The pharmacological discussions lead to a new model of drug taking, which also have a better performance for description of psychological and psychiatric phenomena. Studying the effects of the order of fractional model, obtains an advantage of the fractional order model over the integer order one.
Fungus belongs to the group of eukaryotic organisms. Many of which are pathogens of humans and other animals. More than 35 million people in the world are suffering from fungal nail infections only [1]. Around 1.5 million fungal species are estimated to be present on earth. Out of which only 5% have been formally classified [2]. Out of these around 150 fungal species are classified in the category...
While intelligence analysis has been a primary target domain for visual analytics system development, relatively little user and task analysis has been conducted within this area. Our research community's understanding of the work processes and practices of intelligence analysts is not deep enough to adequately address their needs. Without a better understanding of the analysts and their problems,...
As an encyclopedia, Wikipedia has the advantages of large amount of information, wide coverage and timely updating. The Wikipedia is constructed and shared by all users. Currently, with comparison to the applications of other language resources such as WordNet and Hownet in natural language processing (NLP), Wikipedia is seldom used in NLP by researchers. In this paper, firstly, the main characteristics...
It is a normal method that CAPTCHA is used to distinguish general users from software robots in E-Business website. With the rapid development of reCAPTCHA, traditional simple CAPTCHA is facing the challenge of being cracked, while too complicated CAPTCHA is difficult for users to identify. This paper proposes a novel CAPTCHA based on digital image information hiding, which is easy for users to identify...
This paper proposes a method to obtain the semantic knowledge from an online encyclopedia called Hudong encyclopedia 2(hudong baike). We obtain concepts and then their semantic related concepts and compute the semantic relatedness by utilizing inner hyperlinks and the open category information in Hudong encyclopedia. By comparing our results with human judgments, we show that our relatedness computing...
In the midst of a developing Web that increases its size with a constant rhythm, automatic document organization becomes important. One way to arrange documents is by categorizing them into topics. Even when there are different forms to consider topics and their extraction, a practical option is to view them as document groups and apply clustering algorithms. An attractive alternative that naturally...
Intelligent books are Web-based textbooks that can adapt and improve their content and guide students through graphical example exercises that resemble the diagrams and notations a student might use on paper. The exercises use formal AI systems to analyse students' work, and different AI systems are used for different questions. This brings the issue of how a person can write questions if they are...
