Chinese micro-blog sentiment analysis based on semantic features and PAD model

Abstract: With the increasing impact of social networks, microblog becomes important carrier of information and social interaction for human beings, which contains emotional states that have important research significance. We try to analysis the microblog text with the methods of emotional vocabulary, combining domain knowledge of psychology and affective computing, continuous dimension of emotion psychology PAD model which is adopted as basis of sentiment analysis. Emotional state inherent in the text is analyzed to obtain a more accurate result and achieve purposes of emotional analysis. At the same time, to achieve emotional microblog text computability from the aspect of personal characteristics. Experimental results show that the method can improve the microblog text sentiment analysis accuracy and precision. The method is able to get a good application in the different themes and different emotional features.

The Virtual Construction Site: Knowledge Management in Virtual Environments

Abstract: The purpose of this study is to examine the potential of the virtual construction site as a tool of knowledge management on technological processes of construc-tion production at the university. A digital paradigm that ensures the unity of in-novative and smart technologies in construction education and improves knowledge management tools has become the methodological basis. The authors present the criteria for the effectiveness of teaching technological processes with the help of virtual construction site (digital, professional, personal). The guide-lines for teaching students to make a technological map in construction are pro-posed. The levels of knowledge of modern digital technologies are presented. The practical significance of the study is to present the experience of teaching techno-logical processes using digital content. The social significance lies in the for-mation of a sustainable orientation of students towards the digitalization of con-struction production. Originality of research consists in substantiation of virtual construction site as the effective tool of knowledge management.

The improved hybrid genetic algorithm for solving TSP based on Handel-C

Abstract: Traveling Salesman Problem (TSP) is a kind of classical combinatorial optimization problem that is easy to be described but difficult to be solved. It belongs to NP-hard problem and is applied broadly in practice. Thus rapid and effective solving TSP is very important application value in practice. Genetic Algorithm (GA) is a kind of heuristic global optimization search algorithm that simulates the biology evolutionary system. GA is applied quite broadly to the combinatorial optimization domain. The paper adopts Handel-C language to program for the simple and improved hybrid genetic algorithms that solve TSP. The experiment results show that the performance of the improved algorithm enhances greatly.
