Faced with the massive App software, most users usually view the other users’ comments and marks to selecting the desired App software. Due to the freedom and randomness of the network comments, the inconsistence between the user’s comment and mark makes it difficult to choose App software. This paper presents a method by analyzing the relationships among user’s comment information, the user’s mark and App software information. Firstly, the consistency between user’s comment information and App software information is judged. Then, through analyzing the grammar relationships among the feature-words, adverbs and the feature-sentiment-words in App software’s feature-sentimentword- pairs, the user’s emotional tendency about App software is quantified quantified combining with the dictionary and the network sentiment words. After calculating the user’s comprehensive score of App software, the consistency of App software’s user comment is judged by comparing this score and the user’s mark. Finally, the experimental results show that the method is effective.展开更多

In order to safeguard environmental public interests, many local prosecutorial organizations have practiced environmental public interests litigation. Since Chinese law has not made explicit stipulation on the function of the People's Procuratorate instituting environmental public interest litigation, the plaintiff's subject qualification for environmental public interest litigation instituted by the People's Procuratorate is still in question. In order to propel the People's Procuratorate to completely and fully exercise their power of supervision and prosecution, there shall be corresponding legislation that provides powerful guarantee for the People's Procuratorate instituting environmental public interest litigation.展开更多

In 2006, China issued its National Plans for Medium and Long-term Development of Science and Technology (2006-2020) (NPMLDST). Since 2006, there has been a rapid increase in the number of citations of China's interna- tional papers in the field of communications. In accordance with the goals listed in the NPMLDST, China needs to over- take several competitors by 2020 to be among the top five countries in the field of natural science field. By comparing two Essential Science Indicators (ESI) (i.e., the total number of citations and the number of citations per paper) for China and other countries, China's annual growth rate is found to exceed that of other influential countries in the field of sci- ence and technology, and exhibits evident growth-type characteristics. Besides, our study also shows that the short- age of high-quality academic papers in China is the main obstacle to improving the impact of China's academic publications.展开更多
