It plays an important role in maintaining the coastal ecological environment, and also provides a guarantee for the survival of various organisms. In the past half century, mangrove has been seriously damaged, so it is very important to find an efficient and accurate method to monitor mangrove changes. The remote sensing technology is an important approach to monitor the dynamic changes of mangrove resources and health status. This paper takes the mangrove in Dandou Ocean of Guangxi province as the research area, uses a variety of optical satellite data sources, analyzes the key features of mangrove remote sensing information recognition, and studies the effective methods of mangrove extraction from different data sources. The experimental results show that the accuracy of mangrove extraction is mainly related to the amount of information in the spectrum feature space and the spatial resolution of the data source, and the difficulty of classification is mainly the distinction between terrestrial plants and mangroves. The accuracy of Sentinel-2A satellite using maximum likelihood classification(MLC) and support vector machine classification(SVM) is very close. Landsat8 satellite with medium and low resolution and large number of spectrum feature space and Gaofen-1 satellite with small number of high spatial resolution spectra are more suitable to be extracted by support vector machine classification. The accuracy of landsat8 satellite image extraction by support vector machine classification is the highest, the overall accuracy is 91.42%, and the kappa coefficient is 0.8819.","PeriodicalId":371599,"journal":{"name":"2021 11th International Conference on Information Science and Technology (ICIST)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125745714","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}

However, propagation of fake news becomes a serious issue concerning the public and government due to openness and rapidity of online communication. It is widely concerned how to automatically detect fake news as soon as possible. Nevertheless, most existing methods do not well utilize comments which contain rich semantic information or ignore their effect. Inspired by the revealing role of some comments to the original post, we propose the neural network model which consists of comment-level-attention (CLA) and comment-type-awareness (CTA) for fake news detection. In CLA, we devise the attention mechanism which considers semantic relation between the post and the comments. Based on attention weights we take the weighted sum of different comment representations for the sample as corresponding comment feature, which can capture key comment information. As similar to stance, we assume comments can gather into several different types naturally. Therefore, in CTA, we store comment type representations by the memory matrix which is learned in the training process of sample stream. Comment feature for the sample is aware of the memory matrix, and then corresponding comment type feature is obtained. We concatenate the above two auxiliary features and learned post feature to help detect fake news. Our validation experiments using the Weibo dataset and Pheme dataset demonstrate the effectiveness of the proposed model.","PeriodicalId":371599,"journal":{"name":"2021 11th International Conference on Information Science and Technology (ICIST)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134208304","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}
