With rapid development of information and communication technology, human behavior has extended to mobile internet. In this paper, we studied posting behavior of micro-blog users in mobile internet. Statistical results suggest that there exist significant negative correlation between inter-event time and social concern. This means that users' interest in posting micro-blogs is influenced by social...
Since Jeff Howe introduced the term "crowdsourcing" in 2006 for the first time, crowd sourcing has be come a growing market in the current Internet. Thousands of workers categorize images, write articles or perform other small tasks on platforms like Amazon Mechanical Turk (MTurk), Micro workers or Short Task. In this work, we want to give an inside view of the usage data from Micro workers...
We present our initial experimental findings from the collaborative deployment of network Anomaly Detection (AD) sensors. Our system examines the ingress http traffic and correlates AD alerts from two administratively disjoint domains: Columbia University and George Mason University. We show that, by exchanging packet content alerts between the two sites, we can achieve zero-day attack detection capabilities...
A network of concepts is built from Wikipedia documents using a random walk approach to compute distances between documents. Three algorithms for distance computation are considered: hitting/commute time, personalized page rank, and truncated visiting probability. In parallel, four types of weighted links in the document network are considered: actual hyperlinks, lexical similarity, common category...
Internet is quickly becoming one of the most important parts in social life. As such people could pay more attention to the Internet events. However, it is not clear that which psychological factors influence Internet event attitudes. The present research was to investigate the mechanism of how Big-Five personality and regulatory emotional self-efficacy influence the attitude on Internet event. In...
Increasing moving ability of human and wide distribution of knowledge requires that e-learning system should possess distributed system structure. To better meet individual demand of user e-learning system should integrate with the factor of study context. We presented an agent-based e-learning environment. Our aim was to allow many users to interact collectively and intelligently with the environment...
The internet-based educational technology has been widely used in the medical schools all over the world. It gives a way for teachers to create online self-evaluation tests and for students to take tests without having to turn in a grade to the teachers. To test the hypothesis that internet-based online tests participation/performance is positively correlated with the final score of physiology course,...
This study attempted to investigate the determinants that affecting current Internet shoppers' intention to continually purchase online in one of biggest states in Malaysia. A total of 150 respondents were selected form Johor state, Malaysia and the questionnaires were being personally distributed to the respondents. The data collected is analyzed by statistical methods, such as mean analysis, Pearson...
The problem of measuring semantic similarity between word pairs has been considered as a fundamental operation in natural language processing, such as information retrieval, word sense disambiguation, etc. Nevertheless, developing a computational method capable of generating satisfactory results close to what humans would perceive is still a difficult task somewhat owed to the subjective nature of...
As the dominant tool to access information online, Web search engines still struggle to improve the quality of search results using various methods. Among these methods, query expansion and document refinement are particularly useful and effective. Query expansion aims at generating an expanded query by adding new terms and phrases, but document refinement keeps Web queries invariant and ceaselessly...
This paper regards Web as a semantic lexicon and alleviates the problem of bilingual lexical knowledge acquiring. Based on mix-language Web page counts, four Web bilingual relatedness (WBR) measurements are built. WBR measurements are evaluated by a modified Miller-Charles' dataset and it is found that the measurement based on point-wise mutual information achieves the best performance. Furthermore,...
We investigate the possibility that microRNA could act as an oncogene or tumor suppressor gene. Experimentally verified microRNA targeted genes information are integrated with microRNA and mRNA expression data to study this hypothesis, in which the Pearson correlation coefficient is used to quantify these relations. Cancer related microRNA and genes information are retrieved by literature search....
In recent years, the explicit semantic analysis (ESA) method has got a good performance in computing semantic relatedness (SR). However, ESA method has failed to consider the given context of the word-pair, and generates the same semantic concepts for one word in different word-pairs. It canpsilat exactly determine the intended sense of an ambiguous word. In this paper, we propose an improved method...
It is strong necessary for this study to extent the literature contributions for the effect of resource-based theory on e-CRM study. Based on the theory perspective, the purpose of this study is to expand and achieve a better understanding of a natural e-CRM phenomenon, namely the interaction effect of HR-service capability, IT-service capability, and KM-service capability on its e-CRM process to...
