With the increase of the number of college graduates, the country needs to do much in promoting their employment. Meanwhile as the rapid development of Internet lead to explosive growth of information, the real value needs to be effectively and immediately selected to benefit both employers and employees. This paper aims to propose two content based algorithms, one starting with cold boot and the...
In the process of the rise of Internet, journalism industry has been impact greatly as a traditional media. And as a very important Internet technique to meet the needs of users, personalized recommendation has been paid much more attention currently by a great number of researchers who were engaged in the journalism industry. Personalized recommendation algorithm has been extensively studied, and...
Knowledge-based economic develops rapidly in the 21st century. Formal learning is playing the leading role in school education, some disciplinary knowledge also needs supplement and improvement through informal learning. This passage proposes the way of informal learning based on web2.0 by using the popular social software platform as learning terminal, such as cell phone and computer. It constructs...
The study uses augmented reality (AR) technology to integrate virtual objects into the real learning environment for language learning. The English AR classroom is constructed using the system prototyping method and evaluated by semi-structured in-depth interviews. According to the flow theory by Csikszenmihalyi in 1975 along with the immersive factors from Trevino and Webster in 1992, the proposed...
This paper proposes a role-playing game model with mobile learning (MRPGL) platform, which is an extension of the previous KBIC (Knowledge-Based Intelligent Classroom) system. In addition to the six layers of KBIC structure, MRPGL owns an extra seventh layer game map. The formal definitions of agents, learning activities and learning materials are constructed upon the coordinates of game map. A web-based...
Today, internet of things is on the rapid development stage. Scientific measures for supply chain performance which based on internet of things is an important content of the supply chain management. This article establishes the performance evaluation index system which based on internet of things from five aspects. They are financial, customer, business process, node coordination and information...
Search-based advertising services provided by search engines enable companies to promote their products to internet users based on their queries is now a major online advertising channel. In most search based advertising services, a company sets a budget, selects keywords, bid for each keyword and pay for each click received. Thus the profit of the company highly lies on the reward of each keyword,...
In this paper, we propose a formal model of trust chain from the view of measurement structure and remote attestation. Trust chain is an important technology in Trusted Computing and has received considerable attention. However, related researches on trust chain have some deficiencies such as the coarse granularity, single measurement function and ignorance of influence from run-environment when report...
TASTIER is a research project on the new information-access paradigm called type-ahead search, in which systems find answers to a keyword query on-the-fly as users type in the query. In this paper we study how to support fuzzy type-ahead search in TASTIER. Supporting fuzzy search is important when users have limited knowledge about the exact representation of the entities they are looking for, such...
The emphases of this study are Web log data preprocessing and collaborative filtering. Aiming at user session identification in the process of data preprocessing and analyzing existing algorithms, this paper established a Web log data preprocessing algorithm based on collaborative filtering. Detailed steps of algorithm and an experimental simulation were carried out. The results of the experiment...
As increasingly popular of search engine advertising which displays advertisements alongside the search results in response to user queries, advertisers can issue ads campaigns across different search engines simultaneously for better return of investment and overall clicks. Advertisers typically have a limited budget that should not be overspent, therefore advertisers must decide how to allocate...
Multicast provides an efficient mechanism for a sender to send messages to multiple receivers simultaneously. Designing secure and efficient key agreement schemes is the key requirement of realizing dynamic secure multicast. In this paper, a new identity-based key agreement scheme for dynamic multicast groups using bilinear pairings is proposed. The procedures of secret communications between subgroups...
The goal of this paper is to develop a framework for designing good data repositories for Web applications. The central theme of our approach is to employ statistical methods to predict quality metrics. These prediction quantities can be used to answer important questions such as: How soon should the local repository be synchronized to have a quality of at least 90% precision with certain confidence...
Location-based information contained in publicly available GIS databases is invaluable for many applications such as disaster response, national infrastructure protection, crime analysis, and numerous others. The information entities of such databases have both spatial and textual descriptions. Likewise, queries issued to the databases also contain spatial and textual components, for example, "Find...
This paper describes a middleware framework for integrating heterogeneous building sub-systems on the Internet. The middleware framework is based on the sub-system peer mode, that is all sub-systems are peers. In this model a middleware provides the standard industry interface OPC for all sub-systems, to accommodate different communication interfaces/protocols such as BACnet, LonTalk, API, DDE and...
