Text Mining Analysis Of New Energy Vehicles In China

With the continuous development of society,the scope of people’s daily activities has become larger and larger,so cars are becoming more and more important to our daily lives.However,in recent years,the number of traditional fuel vehicles has increased.While automobiles have brought us convenience in life,they have also caused global negative effects such as "environmental pollution" and "resource shortage",which have attracted great attention from countries all over the world.The birth of new energy vehicles will alleviate these negative effects to a certain extent.Therefore,most countries in the world are advocating the development of pollution-free new energy vehicles.New energy vehicles are bound to become the future development direction of the automotive industry.However,there are still some problems in the current development and status quo of new energy vehicles.People still have concerns about the development of new energy vehicles,especially in the user’s car experience.Therefore,it is of practical significance to analyze people’s views or experience feelings of new energy vehicles through text mining.This article first summarizes the research methods,research status and application of text mining on new energy vehicles by the predecessors through literature analysis,and determines the research methods of this article.Secondly,from a macro perspective,Zhihu’s answer to the opinion on new energy vehicles uses sentiment analysis based on the text classification algorithm of the sentiment dictionary,and at the same time,the semantic network diagram is constructed separately for the positive and negative emotional tendencies.Next,perform a descriptive analysis of the experience of new energy vehicles in different aspects,and compare them with traditional fuel vehicles.Finally,according to the results of the descriptive analysis,the “space” and “manipulation”of domestic new energy vehicles and the performance of new energy vehicles are analyzed."Oil(energy)consumption" carries out LDA theme model analysis to further explore the advantages and disadvantages of current new energy vehicles.Through the analysis results,it is found that most people who care about new energy vehicles are more optimistic about the development of my country’s new energy vehicles.People are most concerned about new energy vehicle batteries and charging technology and national and local government policies.Users are quite satisfied with the overall experience of new energy vehicles,especially in terms of battery life,fuel(energy)consumption,power and noise control,and there is room for improvement in space,control,charging and price.In the space dimension of new energy vehicles,users are most concerned about the space of the rear and trunk;in terms of control,users focus on the sensitivity and accuracy of steering and braking;users are satisfied with energy consumption and also mentioned a lot of " Keywords such as "charging pile" and "charging".It can be seen that these aspects are key factors to further improve the experience of new energy vehicle users.Based on the above analysis results,this article gives the following suggestions: First,for automakers,they should pay more attention to the design of new energy vehicles in terms of space,handling and appearance,while further improving the technology of new energy vehicles in terms of battery and charging.So as to ensure battery life and battery life;secondly,for the state and local governments,they should deeply cooperate with local enterprises to further plan the arrangement of charging piles.At the same time,according to market demand,specific implementation of new energy vehicle subsidy policies,and finally appropriate policies to strengthen battery and charging technology Cultivating talents in various aspects,improving battery and charging technology.
