The Influence Of Semantic Information On Subjective Evaluation Of Soundscape

The population of China continues to rise,and the demand for urban building density has gradually increased.The balance between man and nature is becoming more and more difficult to maintain in cities.The balance between man and land has become one of the important contradictions in urban development.The rapid development of the Internet in the past decade has rapidly reshaped the perception of life and environment in the city.Therefore,the dimension of architecture has expanded from a pure local experience to the Internet.The time and space limitations of architectural perception have been greatly expanded compared to before,and the information on the Internet also has an impact on the perception of architecture and landscape.This article takes the Qunar Travel Network and the famous scenic spot Jichangyuan Harmony Garden as the research object,combining the description of the attractions and the comments of the attractions,through the research methods of data science and natural language processing,the semantic information in the website description is related to the soundscape Study the impact of subjective evaluation.Among the traditional soundscape research methods,commonly used research methods include questionnaire survey,semantic subdivision,focus group and other methods.In the testing process,it always includes more or less semantic communication between the experimenter and the subject,which may affect the subjective evaluation.At the same time,for the experimental design that does not adopt single-blind or double-blind experiments,it may also subjectively increase the attention of sound scene perception,thereby affecting the sound scene perception.Therefore,this article adopts natural data extraction,which is to analyze the past scenic spot comment information,avoiding the possible subjective guidance of the experimental subjects in the process of describing the investigation questions.And through the relevant methods of natural language processing,generate emotional scores and extract relevant indicators of semantic information about soundscapes.In order to study the soundscape as a perceptive dimension of the overall landscape,its awakening degree at the level of perception consciousness,that is,soundscape attention.Soundscape subjective evaluation and soundscape perception are an important research object of soundscape research.Through investigation and analysis,this article finds that the semantic information in the website description will have an impact on the perception and evaluation of the soundscape in the review.In the experimental group with semantic information in the description,the proportion of semantic information in the comments also increased significantly,and the sentiment score was more positive.Then this paper analyzes the comments containing semantic information,starting with the vocabulary selection,vocabulary frequency,vocabulary length,clause length and other factors of semantic information,and combining with the relevant research results of linguistics,the concept and calculation method of semantic information weights are proposed.Semantic information weight is a measure of the attention degree of the impact of semantic information in the description of sound scene perception.The higher the semantic information weight,the more attention the experimenter pays to the auditory level of the landscape at the conscious level.This index can be used as a reference index for soundscape elements in the overall landscape evaluation.The interviewee is the subject of soundscape research.This article also analyzes the meta-information of scenic spot reviews,including the analysis of information such as publishing websites,scenic spots,review times,and user names.Respondents themselves have different levels of perception and expression of sound.The product positioning of the published website is closely related to the users,and the regional nature of the attractions will also have an impact on the psychology of the users.Among them,because the generation time of the travel Internet is relatively short,and the user experience has only formed habits and stickiness in the past ten years,this article analyzes the comment time into daily,weekly,monthly,and yearly.This article only analyzes the correlation and basic statistics.From the principle and mechanism level,there are many research possibilities for mining in the future.In this study,as one of the emerging directions of tourism research,soundscape has attracted more and more attention from scholars at home and abroad.Chinese gardens have a unique position in the world landscape,and are also tourism resources with humanistic value.Their acoustic environment is increasingly valued by users and managers.This article aims to explore a research method that combines the subjective evaluation of landscape and the subjective evaluation of soundscape.Based on the means of data science,under the condition of not emphasizing the user's focus on the elements of soundscape,the impact of semantic information on the subjective evaluation of soundscape is studied..Through analysis methods such as natural language processing,word cloud maps,contour maps,etc.,and based on the evaluation of open source travel websites on the Internet,this article finds that semantic information has an impact on the subjective evaluation of soundscapes,and consistently improves the emotional positiveness of the subjective evaluation of landscapes.Degree,that is,semantic information has a masking effect on the subjective evaluation of soundscape.And based on this,this article gives suggestions on the propaganda and design strategies of the soundscape,focusing on the spread of the soundscape in the future and the improvement of the perceived dimensions and emotional scores in the landscape.
