Tools to generate game-based learning materials are seldom implemented in Massive Open Online Course (MOOC) platforms. First experiments with game-based learning MOOCs had shown good results. In my research, I will focus on the integration of game-based learning to the openHPI MOOC platform. The use of game-based learning materials will be evaluated in three iterations: (1) by existing means the platform...
Learning evaluation in larger online university courses has become a challenge, especially in those cases when learning focuses on the development of professional skills. The objective of this article is to analyze how "authentic Assessment" applied by students correlate with the judgment of the teaching team, in the framework of a course for business and administration students. The results...
While there is a large amount of text data on the Internet, people need to organize the text data with experienced category. However, the flat structure of categories could not satisfy the modern information management. To solve this problem, we propose a hierarchical classification process with a strategy, called candidates, used to relieve the blocking problems. Besides, we establish the description...
Nowadays cross-media retrieval is an useful technology that helps people find expected information from the huge amount of multimodal data more efficiently. A common cross-media retrieval framework is first to map features of different modalities into an isomorphic semantic space so that the similarity between heterogeneous data can be measured. For most of semantic space based methods, the mapping...
With the explosive growth of information on the Internet, it becomes more and more important to improve the efficiency of information acquisition. Automatic text summarization provides a good means for quick acquisition of information through compression and refinement. While existing methods for automatic text summarization achieve elegant performance on short sequences, however, they are facing...

In this research, we conducted a questionnaire survey and interview on the current state of flipped classrooms for university faculty members in order to obtain teacher support methods. The survey showed that flipped classrooms are practiced with various subjects and class sizes, which indicates the necessity of support for a wide range of subjects. In the educational method, the authors found that...
The background of this paper is the issue of how to overview the knowledge of a given query keyword. Especially, we focus on concerns of those who search for Web pages with a given query keyword. The Web search information needs of a given query keyword is collected through search engine suggests. Given a query keyword, we collect up to around 1,000 suggests, while many of them are redundant. We cluster...
Linking the growing IPv6 deployment to existing IPv4 addresses is an interesting field of research, be it for network forensics, structural analysis, or reconnaissance. In this work, we focus on classifying pairs of server IPv6 and IPv4 addresses as siblings, i.e., running on the same machine. Our methodology leverages active measurements of TCP timestamps and other network characteristics, which...
Social media constitute nowadays one of the most common communication mediums. Millions of users exploit them daily to share information with their community in the network via messages, referred as posts. The massive volume of information shared is extremely diverse and covers a vast spectrum of topics and interests. Automatically identifying the topics of the posts is of particular interest as this...
The financial market is very fickle and investors have the difficult task of following and trying to predict the swings of the market so that their strategies result in better financial returns. With the use of Big Data and Bayesian mathematical statistics based on prior knowledge and examples of training to determine the likelihood of a hypothesis, financial news can be tracked continuously and affecting...
The computer interaction may be an alternative to developing cognition in older people. The objective of the study was to evaluate the cognitive functions of elderly people who participated in interaction processes in a social network on the Internet. The research is a randomized, interventional and descriptive-analytical clinical type. The study sample consisted of 41 elderly women from Brazil. The...
with the development of Internet, many companies announced the stock information by various medium, and stock buyers comment that information as well as make rational investment strategies to maximize their profit. At present, many retail investors, who lack of channels to obtain real information, scarce professional knowledge of investment theory and easy to be affected by public opinion of Internet,...
In this paper we propose and evaluate three approaches for automated classification of texts in over 60 languages without the need for a manually annotated dataset in those languages. All approaches are based on the randomized Explicit Semantic Analysis method using multilingual Wikipedia articles as their knowledge repository. We evaluate the proposed approaches by classifying a Twitter dataset in...
Here, we present and discuss a proposal of activities for the teaching of ICT, using the web-based platform Edmodo, to be developed within the framework of Adult Education and Training courses. It is based on the experience gained in the teaching of this type of course throughout the academic year of 2015/2016, in a school of the District of Vila Real, Portugal. We also present the framework that...
Different from general-purpose search engines, vertical search engine only needs to collect and index only a specific knowledge domain, and then provides more professional search services for users. In this paper, we propose a novel library resource vertical search engine based on ontology technology. In the vertical search engine, the information that crawler collects from Internet should be further...

At the same time, the modern vocational education advocates “work and study, the integration of theory and practice, do in Teaching, learning by doing.” Numerical...
This paper introduces an automatic categorical-marking model for text categorization. Traditional classification algorithms are generally applying labeled training set and call for a lot of manual work to tag classifications beforehand. Also due to the ambiguity and fuzziness of texts, the results of traditional text categorization algorithms may not be clear enough and abundant in content. This paper...
