Incident and Problem Ticket Clustering and Classification Using Deep Learning

A holistic analysis of problem and incident tickets in a real production cloud service environment is presented in this paper.By extracting different bags of words,we use principal component analysis(PCA)to examine the clustering characteristics of these tickets.Then Kmeans and latent Dirichlet allocation(LDA)are applied to show the potential clusters within this Cloud environment.The second part of our study uses a pre-trained bidirectional encoder representation from transformers(BERT)model to classify the tickets,with the goal of predicting the optimal dispatching department for a given ticket.Experimental results show that due to the unique characteristics of ticket description,pre-processing with domain knowledge turns out to be critical in both clustering and classification.Our classification model yields 86%accuracy when predicting the target dispatching department.

Preliminary Study on Selling Tickets in Reason for Last Trains on Beijing Rail Transit Network

With the increase of Beijing urban rail transport network, the structure of the road network is becoming more complex, and passengers have more travel options. Together with the complex paths and different timetables, taking the last train is becoming much more difficult and unsuccessful. To avoid losses, we propose feasible suggestions to the last train with reasonable selling tickets system.

The Research of Event Detection and Characterization Technology of Ticket Gate in the Urban Rapid Rail Transit

Making events recognition more reliable under complex environment is one of the most important challenges for the intelligent recognition system to the ticket gate in the urban rapid rail transit. The motion objects passing through the ticket gate could be described as a series of moving sequences got by sensors that located in the walkway side of the ticket gate. This paper presents a robust method to detect some classes of events of ticket gate in the urban rapid rail transit. Diffused reflectance infrared sensors are used to collect signals. In this paper, the motion objects are here referred to passenger(s) or (and) luggage(s), for which are of frequent occurrences in the ticket gate of the urban railway traffic. Specifically, this paper makes two main contributions: 1) The proposed recognition method could be used to identify several events, including the event of one person passing through the ticket gate, the event of two consecutive passengers passing through the ticket gate without a big gap between them, and the event of a passenger walking through the ticket gate pulling a suitcase;2) The moving time sequence matrix is transformed into a one-dimensional vector as the feature descriptor. Deep learning (DL), back propagation neural network (BP), and support vector machine (SVM) are applied to recognize the events respectively. BP has been proved to have a higher recognition rate compared to other methods. In order to implement the three algorithms, a data set is built which includes 150 samples of all kinds of events from the practical tests. Experiments show the effectiveness of the proposed methods.

Analyze China High-Speed Railway Ticket for Spring Transportation from the Perspective of Microeconomics

In recent ten years, the rapid development of China high-speed railway is called "China miracle", and it not only provides great convenience for people's daily life trip, but also greatly promotes the economic development. However, the annual spring transportation in the special period is still a great challenge to high-speed railway transportation, and this paper analyzes the high-speed railway ticket for spring transportation from the perspective of microeconomics, and then thinks for the solution. This paper specifically analyzes the problem that demand exceeds supply for high-speed railway ticket by using the theories of the demand elasticity of supply and demand and the influence of price on supply and demand, monopoly markets. In addition, opportunity cost, incomplete information and other economic principles are used to think about the theoretical reasons for the difficulty of buying tickets during the spring transportation. I have given my understanding for the two problems owned by China spring transportation, and the corresponding countermeasures and suggestions. For example, speed up the development of substitutes and carry out the mechanism of price fluctuation;In the ticket refunding mechanism, this paper boldly conceives the method to relieve the pressure through a reasonable and scientific ticket refunding mechanism. Finally, this paper starts from the source and find the key point to solve the problem of spring transportation in China by breaking the urban-rural dual structure. Hereafter the final conclusion was drawn: Although there are some problems to cope with the spring transport for the current China high-speed railway, it is believed that in the near future, the difficulty of buying a ticket in spring transportation will no longer hinder the homecoming of wanderers.

An Initial Approach for a NFC M-Ticketing Urban Transport System

Public transport plays an important role in the daily lives of hundreds of millions of people. The limited national and local finances starve the public transport networks of funding, although greater usage would imply important environmental and financial benefits. The recent advances in mobile technologies and services could be harnessed to increase the attractiveness and efficiency of various public transport systems. Increasingly flexible electronic ticketing, smart cards and real-time information feeds via smartphones are making transportation networks faster, cheaper and more efficient for both the passengers and operators. In this paper, we present our approach in designing and implementing an M-ticketing system for urban transport based on NFC technology. We make initial design decisions based on a study of two similar systems Oyster and U-Go. We make use of Microsoft technologies for the prototype implementation and we propose a test suite to validate the system. We conclude on presenting the experience gained from this project and propose a set of further developments in order for the prototype to become more realistic.

Factors Influencing the Adoption of E-Ticketing System in the Bus Transport Sector in Ghana

Electronic ticketing (E-ticketing), an innovative mode of issuing and delivering tickets, is becoming prevalent and is employed by many transport companies in Europe, America, Asia, and some parts of Africa to reduce the cost that goes with printing tickets. This study investigated E-ticketing adoption in the bus transport sector in the Kumasi Metropolis of Ghana. The study applied the Technology Acceptance Model (TAM), and the Structural Equation Modelling technique was used to analyse the factors affecting the intention to use the E-ticketing system. In that regard, the study was based on perceived usefulness, perceived ease of use, subjective norms, and demographic variables. Quantitative research approaches were used by distributing questionnaires to 392 passengers, employing the cluster and random sampling techniques. Findings from the study showed that perceived usefulness and subjective norm were the significant factors affecting passengers’ intention to adopt the E-ticketing system. Besides, perceived ease of use and subjective norms were significant in predicting passengers’ perceived usefulness of adopting E-ticketing system. The findings of this research will provide the government, industrial players, and the entire public a better understanding of the perceived factors that could enhance or serve as a barrier to passengers’ adoption of the E-ticketing system. This can also lead to the development of effective E-ticketing marketing strategies.

How to Buy Train Tickets

Compared to bus and plane tickets, buying train tickets can be tricky for tourists who want to travel by rail during their visit to China. Tickets for busy routes and popular destinations can sell out, and it can be particularly difficult to get tickets for travel during long holidays, for example the two week-long holidays： National Day Holiday （October1-7） and Chinese New Year.

The Awakening of Feminist Consciousness in D.H.Lawrence's Tickets,Please

D. H. Lawrence's"Tickets, Please"displays a wartime love story between Coddy and Annie. In their love affairs, Coddy, the man of impotence deems his freedom much as before while Annie switches back to the traditional female role to consider marriage as the ultimate goal. In"Tickets, Please", the incidental effects of progress on humanity are shown through the Lawrentian central theme of the relationship between men and women. Here, the weaker sex and the stronger sex are respectively and ironically embodied by Annie Stone and John Thomas Raynor. This paper analyzes the wartime setting, the tram girls and the love struggle between Annie and Coddy. Through these analyses, the paper reveals the awakening of feminist consciousness in the story.

高速铁路旅客购票时间选择行为研究

研究高速铁路旅客的购票行为对铁路企业预测需求、优化票价、分配票额等具有重要意义。考虑旅客个体和群体层面的异质性,分别构建混合和潜在类别Logit模型,研究出行时段、票种和供需关系等因素对旅客购票时间选择的影响。利用售票数据估计模型参数,得到高速铁路旅客购票时间选择的规律:一天中下午和晚上出行的旅客在出行当日或前一天购票的可能性更高;购买全价票、儿童票、半价票的旅客偏向于在距离出发日9~30 d内购票,免票旅客往往选择随到随走;供需关系会显著影响旅客的购票时间选择而且越临近出发日影响越显著。进一步结合预售期购票量预测值和旅客购票选择概率,计算各预售阶段的购票量,可为铁路企业制定票额预分和浮动票价等策略提供决策依据。
