This paper used GDELT database as data source and obtained full text data of English news in 25 countries along \u2018the Belt and Road\u2019. The paper also introduced the topic model, combined with the unsupervised method (latent Dirichlet allocation, LDA) and the supervision method (labeled LDA) to mine the topics contained in the news data. It constructed the transportation development model and analyzed the development trend of transportation in various countries. The study found that the development trend of transportation in the countries along the line is unbalanced, which can be divided into four types: rapid development type, stable development type, slow development type and lagging development type. The method of this paper can effectively extract temporal and spatial variation of news events, discover potential risks in various countries, support real-time and dynamic monitoring of the social development situation of the countries along the border and provide auxiliary decision support for implementation of the \u2018the Belt and Road\u2019 initiative, which has important application value.<\/jats:p>","DOI":"10.1093\/comjnl\/bxaa102","type":"journal-article","created":{"date-parts":[[2020,7,7]],"date-time":"2020-07-07T19:09:14Z","timestamp":1594148954000},"page":"337-346","source":"Crossref","is-referenced-by-count":0,"title":["Transportation Index Computation: A Development Theme Mining-Based Approach"],"prefix":"10.1093","volume":"64","author":[{"given":"Gang","family":"Han","sequence":"first","affiliation":[{"name":"Postdoctoral Programme of Management Science and Engineering, Beijing Jiaotong University, Beijing 100044, China"}]},{"given":"Menggang","family":"Li","sequence":"additional","affiliation":[{"name":"National Academy of Economic Security, Beijing Jiaotong University, Beijing 100044, China"},{"name":"Beijing Laboratory of National Economic Security Early-warning Engineering, Beijing Jiaotong University, Beijing 100044, China"},{"name":"Beijing Center for Industrial Security and Development Research, Beijing Jiaotong University, Beijing 100044, China"}]},{"given":"Yiduo","family":"Mei","sequence":"additional","affiliation":[{"name":"Postdoctoral Programme of China Centre for Industrial Security Research, Beijing Jiaotong University, Beijing 100044, China"}]},{"given":"Deming","family":"Li","sequence":"additional","affiliation":[{"name":"School of Economics and Management, Beijing Jiaotong University, Beijing 100044, China"}]}],"member":"286","published-online":{"date-parts":[[2020,9,15]]},"reference":[{"key":"2021120506111373000_ref1","first-page":"1005","article-title":"One belt and one road: the grand geo-strategy of China\u2019s rise","volume":"34","author":"Debin","year":"2015","journal-title":"Geogr.
