Users from all over world share their comments and sentiments on the Internet become a new tradition. Applying natural language processing technology to analyze the text on the Internet for mining the emotional tendencies has become the main way in the social public opinion monitoring and the after-sale feedback of manufactory. Thus, the study on text sentiment analysis has shown important social significance and commercial value. Sentiment analysis is a hot research topic in the field of natural language processing and data mining in recent ten years. The paper starts with the topic of \"Sentiment Analysis using a CNN-BiLSTM deep model based on attention mechanism classification\". First, it conducts an in-depth investigation on the current research status and commonly used algorithms at home and abroad, and briefly introduces and analyzes the current mainstream sentiment analysis methods. As a direction of machine learning, deep learning has become a hot research topic in emotion classification in the field of natural language processing. This paper uses deep learning models to study the sentiment classification problem of short and long text sentiment classification tasks. The main research contents are as follows. Firstly, Traditional neural network based short text classification algorithms for sentiment classification is easy to find the errors. The feature dimension is too high, and the feature information of the pool layer is lost, which leads to the loss of the details of the emotion vocabulary. To solve this problem, the Word Vector Model (Word2vec), Bidirectional Long-term and Short-term Memory networks (BiLSTM) and convolutional neural network (CNN) are combined in Quora dataset. The experiment shows that the accuracy of CNN-BiLSTM model associated with Word2vec word embedding achieved 91.48%. This proves that the hybrid network model performs better than the single structure neural network in short text. Convolutional neural network (CNN) models use convolutional layers and maximum pooling or max-overtime pooling layers to extract higher-level features, while LSTM models can capture long- term dependencies between words hence are better used for text classification. However, even with the hybrid approach that leverages the powers of these two deep-learning models, the number of features to remember for classification remains huge, hence hindering the training process. Secondly, we propose an attention based CNN-BiLSTM hybrid model that capitalize on the advantages of LSTM and CNN with an additional attention mechanism in IMDB movie reviews dataset. In the experiment, under the control of single variable of Data volume and Epoch, the proposed hybrid model was compared with the results of various indicators including recall, precision, F1 score and accuracy of CNN, LSTM and CNN-LSTM in long text.

Therefore, this study aims to enhance our understanding of people's response to the COVID-19 pandemic and their perception regarding aviation safety. Specifically, the study investigates whether in-flight services focusing on sanitation and preventative measures against the virus alleviated negative emotions such as fear and anxiety among passengers, and how this affected their risk perception and group efficacy through cognitive value. To achieve the purpose of the study, an online survey was conducted in December 2021 of passengers with experience boarding aircraft after the COVID-19 outbreak, and 211 valid responses out of 308 were used for analysis. The analysis of the data revealed that in-flight services had a positive effect on cognitive value, which in turn had a positive effect on risk perception and collective efficacy among air passengers. The overall evaluation of in-flight services indicated that passengers now place a greater emphasis on hygiene and quarantine measures. Furthermore, there has been a notable promotion of passengers' efforts and attitudes towards not only ensuring their own safety but also the safety of others and society, which has resulted in a significant improvement in responsible behavior.

In particular, due to the own nature of the aviation industry which is sensitive to external factors of the rapidly changing world, one of the important strategic goals to occupy a firm competitive advantage is securing regular customers such as \"Loyal Customer.\" The purpose of this study is to find out not only the price competitiveness of airlines but also the influence among relationship commitment, brand attachment, and relationship persistence intention in order to survive the fierce competition in the airline industry. Based on that, it is intended to develop strategies that can be used to maintain existing customers and attract new customers to find ways to be more competitive for each airline. The questionnaire consisted of four factors: Frequent flyer programs, relationship immersion, brand attachment, and relationship persistence intention and the survey subjects were passengers using airlines. Statistical processing of the collected data was analyzed using the SPSS v. 25.0 statistical package program. It was found that the relationship immersion according to the frequent flyer programs affected both the love dimension and the solidarity dimension factors of brand attachment. In addition, it was found that both emotional immersion and computational immersion, which are sub-factors of relationship immersion, had a significant effect on relationship persistence intention. The detailed factors of the frequent flyer programs to improve the relationship immersion of airlines were identified and the factors affecting the relationship persistence intention were identified. Also, it was confirmed that relationship immersion was an essential factor to increase brand attachment and relationship persistence intention of customers to the airlines. Through this, this study would contribute to play a big role in developing strategies that can be used to maintain existing customers and attract new customers, and presenting a framework for utilizing existing customer relationship marketing.

Valero","doi":"10.3390/INFO12100427","DOIUrl":"https://doi.org/10.3390/INFO12100427","url":null,"abstract":"Information orders play a central role in the mathematical foundations of Computer Science. Concretely, they are a suitable tool to describe processes in which the information increases successively in each step of the computation. In order to provide numerical quantifications of the amount of information in the aforementioned processes, S.G. Matthews introduced the notions of partial metric and Scott-like topology. The success of partial metrics is given mainly by two facts. On the one hand, they can induce the so-called specialization partial order, which is able to encode the existing order structure in many examples of spaces that arise in a natural way in Computer Science. On the other hand, their associated topology is Scott-like when the partial metric space is complete and, thus, it is able to describe the aforementioned increasing information processes in such a way that the supremum of the sequence always exists and captures the amount of information, measured by the partial metric; it also contains no information other than that which may be derived from the members of the sequence. R. Heckmann showed that the method to induce the partial order associated with a partial metric could be retrieved as a particular case of a celebrated method for generating partial orders through metrics and non-negative real-valued functions. Motivated by this fact, we explore this general method from an information orders theory viewpoint. Specifically, we show that such a method captures the essence of information orders in such a way that the function under consideration is able to quantify the amount of information and, in addition, its measurement can be used to distinguish maximal elements. Moreover, we show that this method for endowing a metric space with a partial order can also be applied to partial metric spaces in order to generate new partial orders different from the specialization one. Furthermore, we show that given a complete metric space and an inf-continuous function, the partially ordered set induced by this general method enjoys rich properties. Concretely, we will show not only its order-completeness but the directed-completeness and, in addition, that the topology induced by the metric is Scott-like. Therefore, such a mathematical structure could be used for developing metric-based tools for modeling increasing information processes in Computer Science. As a particular case of our new results, we retrieve, for a complete partial metric space, the above-explained celebrated fact about the Scott-like character of the associated topology and, in addition, that the induced partial ordered set is directed-complete and not only order-complete.","PeriodicalId":50362,"journal":{"name":"Information-An International Interdisciplinary Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77860839","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}
