Tourist travel texts collected from Ctrip.com and Mafengwo are used as research samples. Based on the \"cognition-emotion\" model of tourist destination image perception, the high-frequency feature words of Guilin image perception are extracted by text analysis method. The results show that: (1) Yangshuo, Li River, and Yulong River are the basic cognitive images of tourists for Guilin’s tourism image. (2) Tourists are highly satisfied with tourism resources and tourism activities, and the evaluation is mainly based on neutral emotions. (3) The overall image perception is a landscape tourist attraction, the overall image perception is positive, and the overall positive perception accounts for a high proportion. (4) The travel notes semantic network diagram takes Guilin as the core, and Guilin-Yangshuo, Guilin-Lijiang, and Guilin-Yulonghe are closely related relation chains in the network diagram.","PeriodicalId":156653,"journal":{"name":"Proceedings of the International Conference on Information Economy, Data Modeling and Cloud Computing, ICIDC 2022, 17-19 June 2022, Qingdao, China","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129795631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, based on the price data of gold and bitcoin from 9/11/2016 to 9/10/2021, the corresponding mathematical models are established by the LSTM, evaluation model, and single-objective optimization model in an attempt to obtain the optimal investment strategy. Firstly, the price is predicted by the LSTM model after data cleaning. The evaluation system is constructed from three perspectives: market trading intention, price stability and market environment trend. Based on the scores and thresholds of the evaluation system, the trading directions (buy, sell, hold) are obtained qualitatively. Then, based on the corrected predicted price, a single-objective optimization is established for maximizing total assets, obtaining the final investment strategy, where an initial $1,000 asset is able to reach a final total asset of $134,226 after five years. Secondly, we establish the evaluation system of investment strategies and establish three evaluation indexes of Sharpe Value, Max Drawdown, and Interest Rate in terms of both return and risk. We construct four new investment strategies with different types of investment product and model selection. Comparing the five investment strategies, we can find that our investment strategy has the highest Interest Rate, higher Sharpe Value, and smaller Max Drawdown compared with other investment strategies. Thirdly, we test the impact of transaction costs on the model and learn that the model is more sensitive to the change of bitcoin transaction costs and not sensitive to the change of gold transaction cost.","PeriodicalId":156653,"journal":{"name":"Proceedings of the International Conference on Information Economy, Data Modeling and Cloud Computing, ICIDC 2022, 17-19 June 2022, Qingdao, China","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121801875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the growth of social economy, people's living conditions have improved, and they have sufficient material conditions to travel to meet the needs of spiritual civilization. Under this premise, China's tourism economy has developed rapidly. In order to study the factors that promote the development of China's tourism economy and promote the development of China's economy as a whole, this study conducts an empirical study on the relationship between tourism economic growth and urban-rural income gap. This study selects China's economic data from 1994 to 2016, establishes a vector autoregression model, and uses the methods of ensemble analysis and Granger causality test to conduct an in-depth study of the relationship between China's tourism economic growth and urban-rural income gap. analyze.
