Engineering ethics is essentially a practical ethics. It exists in all aspects of the conceptual design to project implementation. This article sorts out the major ethical problems in the practice of engineering, including security, effectiveness evaluation, ecological and ethical issues, public rights, conflict of interest issues; and points out the causes of these problems: the uncertainty of engineering...
The traditional medians are now challenged by the new media. For the law-makers the character of new media is different from the traditional counterparts, therefore, more related reforms are also demanded in the Chinese society. The characters of new media include: interactivity, quasi-networks and market domination. Reforms demanded then are to establish independent new media networks and a media...
In this paper, the automatic prediction of micro-blog users' attribute information is modeled as a multi-label classification process considering the relevance and co-occurrence of user attributes instead of single-label or regression, where each user has more than one attribute. Two basic and one improved multi-label classification methods are evaluated and compared in this task. Taking micro-blogging...
Balanced Graph Partitioning is one of the fundamental combinatorial optimization problems. It is still a challenge to effectively achieve a High-quality Balanced Graph Partitioning for super-large graphs. In this paper, we propose a graph partitioning algorithm based on Label Swapping. Normalized Cut is used as optimization target and this algorithm iteratively updates the graph with Label Swapping...
Using the new uncertainty indexes from Baker et al. (2012), we investigate the effect of economic policy uncertainty in the United States on export duration of Chinese industrial enterprises. The empirical results show that economic policy uncertainty in the United States is negatively related to the duration of export and the conclusion is robust when we adopt different economic policy uncertainty...
The development of computer science and applications changes with each passing day. The software companies and research institutions put forward higher requirements for computer science majors' professional capacity and creative ability. However, many problems still exist in the current status of teaching computer science majors and directly affect the quality of professional training, so it brings...
In this work, we are studying a basic economic system of producer agents situated in a 2D world and how it is affected by decisions to initiate war. We are considering survival wars and wars initiated by culturally inherited stress, pugnacity, perception of wealth inequality and greed, which is perception of intangible status inequality. We show through agent-based modelling that cultural evolution...
This paper proposes a Research paper Similarity system that measures the similarity of an input paper with other papers based on the summarized version of each paper. Currently, This system will take into account 2 different types of summarization for papers based on the different types of keywords,i.e, Normal keywords and Stemmed keywords. On the contrast to the current and existing recommendation...
There are a lot of Human resource companies and other business companies that are experiencing difficulties in selecting applicants that would fill their vacant job positions. They usually use the traditional way of selecting applicants like series of interviews, trainings and giving probationary period to employees at work before they can finally decide if they will employ the applicant or not. On...
Semantic relatedness or semantic similarity between words is an important basic issue for many Natural Language Processing (NLP) applications, such as sentence retrieval, word sense disambiguation, question answering, and so on. This research issue attracts many researchers, but most of studies focus on improving the effectiveness, i.e., applying kinds of techniques to improve precision (effectiveness)...
Determining the influence or strength of a country has become increasingly important for the world's politics, economics, culture, foreign policy, international trade, military, among others. While the issue has been tackled by researchers for decades, the results obtained so far have been largely static and unsatisfactory. By constructing daily matrices from a massive political events data, the Global...
Currently microblog search engines have the function to find related users according to input topic keywords. Traditional approaches rank users by their authentication information or their self descriptions (introductions or labels).However, many users may not publish the posts closely related to their certification profile. In this paper, we study the problem of identifying domain-dependent influential...
Many listed companies in Shenzhen and Shanghai just leave from traditional business models and begin construct their modern accounting system. The transparency of financial statements quietly attract attention in these backgrounds. This study identifies that the world's second largest stock market has contrarian profit. Momentum profit for Shenzhen, Shanghai and Hong Kong are all negative and differ...
We study a housing pricing model with heterogeneous agents including house buyers, investors and property developers. Each agent maximizes his own objective subject to financial constraints. Without investors in the housing market, the equilibrium housing price is determined by cost and demand. In contrast, if investors exist in the housing market, the equilibrium housing price may persistently deviate...
Microblog is one of the most influential social media platforms. Timely prediction of the popular tweet in microblog is of great value in monitoring emergency monitoring, public opinions, personalized recommendations, marketing and other areas. This paper presents our improved method for predicting popularity of tweet in microblog. Firstly, we propose some new dynamic features, such as retweet depth,...
Portable personalization service has been proved very useful in the sharing and reusing of user personalized profiles among different platforms. We present an approach of a Web requesting framework for portable personalization service based on iterative profiling algorithm with time unit of weighted keywords and give a detailed explanation about its ideas and design principles. Some important challenges...
Influenced by the fusion of Internet Plus and education, Nanjing University of Finance and Economics launches the construction of “Intelligent Campus” through the application of NFC Smart Campus Card. Through reviewing the functions of NFC mobile phone smart campus card, the multiple application scenes on campus are demonstrated and the advantages are indicated as multi-function, optimized user experience,...
With more and more social public attention from microblog opinion leaders, they have gradually become the essential role to publicize information and influence public opinion in microblog platform, whose ability in monitoring and guiding public opinions also causes public focus.

As an advanced artificial intelligence technology, error back-propagation (BP) neural network algorithm has been widely applied to electronics, communications, automation and other fields. However, traditional BP neural network algorithm has the disadvantages, such as inclination to stick into local optima, and slow convergence, which exert a great impact on the processing performance, and also limit...
