Research On Android Application Quality Evaluation System Based On Soft Sets

In recent years,with the rapid development of mobile communication technology,the mobile internet is gradually changing the world.The Android system,as currently holds the world's highest market share in mobile phone operating system have become more and more popular ever since it's been introduced because of its open properties.Since the release of the first Android device HTC G1,Android's market share has steadily improved in recent years.And it had held the largest mobile operating system market share in the past two years.Almost all of the domestic mobile phone manufacturers are producing Android-based mobile phone operating system,such as Huawei,Xiaomi,Lenovo and so on.The global security Android users has exceeded one billion.It is foreseeable that Android systems in the coming years will continue to lead the mobile Internet,playing an important role in the big data,mobile payment,cloud computing and other new technologies.At the same time,a large number of Android mobile phone applications have been developed.Users,in the face of so many applications usually,can not have a fast and efficient choice.Developers are scrambling to develop a variety of applications software applications,leading Android application market confusion.At the same time due to the lack of effective evaluation model,making it difficult for application developers to understand the problems of their own products.So it is essential and reasonable to evaluate the quality of Android applications.Soft set theory is a new mathematical tool to deal with uncertainty problems,the way it describes objects very is flexible.This research will apply soft set theory to the soft Android application quality evaluation,making up the difficulty of traditional methods when describing uncertain issues.The main contents and results are as follows:Firstly,on the basis of the relevant literature on software quality evaluation and research of soft set,this research explains the meaning of software quality and summarizes several commonly used modeling software quality evaluation.Secondly,this research,on the basis of past research,sums up the principles of constructing software quality evaluation index,and thus teases out the Android application quality evaluation index system.The system consists of 3 first-level indicators and 11 secondary indicators.Thirdly,this paper introduces the definition and algorithm of soft set and of bijective soft set decision system,and definitions of related dependence and importance,it also presents a reducing method approach based on the importance.Fourth,the paper obtains raw data of Android application quality evaluation through questionnaires,transforming raw data into Android applications decision system containing five Android applications,and then calculates the degree of importance of each indicator.So this paper proposes a new method to evaluate the quality of Android applications.The results show that strengthening the interface design level is the key to improve the overall quality.Finally,through the empirical analysis concluded,that the model is proven a reasonable model to evaluate the quality of Android applications.It can parameterize qualitative and quantitative information,digging out valuable information.This paper has proposed suggestions to Android software developers,providing theoretical and practical reference.
