考虑开发者兴趣迁移的开源项目推荐方法

社交化编码是当前软件开发生产的一个重要方式,其开发模式的灵活性与开放性吸引了大量的开发者.开发者通过参与开源项目能够提升自己的开发能力并在社区中形成自己的影响力.许多开源社区如GitHub上有大量的开源项目.开发者将花费大量的时间与精力去寻找自己感兴趣的项目.开源项目推荐引起了研究者的兴趣,然而,目前的方法中仅仅基于开发者过去参加过的项目的相似性进行项目推荐,没有对开发者的兴趣迁移进行考虑.针对这一问题,本文提出了一种基于项目主题迁移频繁模式挖掘的推荐算法.该方法结合了概率主题模型与顺序频繁模式挖掘,并考虑项目社交关联和流行度,从而为开发者提供个性化开源项目推荐.本文所提方法的召回率比传统的方法高出了10.9%,推荐效果显著提升.

基于开发者行为分析的Web资源推荐

现代的软件开发集成开发环境(IDE)为开发者提供了错误提示、代码补全、代码分析、版本管理等多方面的辅助开发支持,大大提高了开发效率。同时,开发者在日常开发过程中还常常依赖于互联网获取代码样例、配置说明、错误处理等Web开发资源。由于需要频繁地在IDE和浏览器之间进行切换并通过各种方式进行信息检索,开发者往往需要在Web开发资源的获取上花费大量的时间和精力。为此,提出一种基于开发者开发行为分析和挖掘的Web信息资源推荐方法。该方法通过自动记录和抓取开发者在IDE中的代码浏览和修改等动作以及在浏览器中的页面浏览信息获取基础信息。在此基础上,该方法从所抓取的浏览器页面中抽取结构化的信息资源,并通过聚类和基于时间的关联分析确定IDE开发行为与Web信息资源之间的相关性,从而在开发者在IDE中执行开发任务时自动推荐相关的Web信息资源。最后通过一个实验分析初步验证了所提方法的有效性。

A resource integration approach for HTML5 mobile applications

As the new HTML5 specification is being accepted, comprehensive HTML5-based mobile applications provide users with better experiences. Huge amount of existing Internet-based resources are rapidly integrated into mobile applications based on HTML5. However, this could result in some difficulties in adapting the resources into various types of existing mobile devices. To enhance the utilization of existing HTML5 based Internet resources into various mobile terminals, this paper proposed a new integration approach for mobile web applications, which can assist application service providers to provide HTML5-based mobile hybrid applications for various types of mobile ends. It is a novel attempt to quickly transplant huge emerging HTML5 Internet resources into mobile applications accepted by various mobile terminals. This work also examines necessary mechanisms and means to support the proposed framework seamlessly working with existing infrastructures. Finally, a prototype integration platform is built and comprehensive simulations are implemented to test and prove its high feasibility.     

Eco System: an Internet commerce architecture

Robust electronic commerce will require several proprietary systems to interoperate. CommerceNet is proposing Eco System, a cross industry effort to build a framework of frameworks, involving both e-commerce vendors and end users. Eco System will consist of an extensible object oriented framework (class libraries, application programming interfaces and shared services) from which developers can assemble applications quickly from existing components. These applications could subsequently be reused in other applications. We are also developing a Common Business Language (CBL) that lets application agents communicate using messages and objects that model communications in the real business world. A network services architecture (protocols, APIs, and data formats) will insulate application agents from each other and from platform dependencies, while facilitating their interoperation. Functionally, Eco System fills three distinct roles. It is: a layer of middleware that facilitates agent interoperation through services such as authentication, billing, payment, and directories; an object oriented development environment that encourages the reuse of e-commerce modules (even modules that represent the product line of an entire company); and an industry roadmap and interoperability example that promotes open standards and helps technology vendors communicate with end users about product features     

Context-aware recommendations through context and activity recognition in a mobile environment

The mobile Internet introduces new opportunities to gain insight in the user’s environment, behavior, and activity. This contextual information can be used as an additional information source to improve traditional recommendation algorithms. This paper describes a framework to detect the current context and activity of the user by analyzing data retrieved from different sensors available on mobile devices. The framework can easily be extended to detect custom activities and is built in a generic way to ensure easy integration with other applications. On top of this framework, a recommender system is built to provide users a personalized content offer, consisting of relevant information such as points-of-interest, train schedules, and touristic info, based on the user’s current context. An evaluation of the recommender system and the underlying context recognition framework shows that power consumption and data traffic is still within an acceptable range. Users who tested the recommender system via the mobile application confirmed the usability and liked to use it. The recommendations are assessed as effective and help them to discover new places and interesting information.     

Hybreed: A software framework for developing context-aware hybrid recommender systems

This article introduces Hybreed, a software framework for building complex context-aware applications, together with a set of components that are specifically targeted at developing hybrid, context-aware recommender systems. Hybreed is based on a concept for processing context that we call dynamic contextualization. The underlying notion of context is very generic, enabling application developers to exploit sensor-based physical factors as well as factors derived from user models or user interaction. This approach is well aligned with context definitions that emphasize the dynamic and activity-oriented nature of context. As an extension of the generic framework, we describe Hybreed RecViews, a set of components facilitating the development of context-aware and hybrid recommender systems. With Hybreed and RecViews, developers can rapidly develop context-aware applications that generate recommendations for both individual users and groups. The framework provides a range of recommendation algorithms and strategies for producing group recommendations as well as templates for combining different methods into hybrid recommenders. Hybreed also provides means for integrating existing user or product data from external sources such as social networks. It combines aspects known from context processing frameworks with features of state-of-the-art recommender system frameworks, aspects that have been addressed only separately in previous research. To our knowledge, Hybreed is the first framework to cover all these aspects in an integrated manner. To evaluate the framework and its conceptual foundation, we verified its capabilities in three different use cases. The evaluation also comprises a comparative assessment of Hybreed’s functional features, a comparison to existing frameworks, and a user study assessing its usability for developers. The results of this study indicate that Hybreed is intuitive to use and extend by developers.     

Easy come or easy go? Empirical evidence on switching behaviors in mobile payment applications

Switching behaviors of mobile payment application received scarce attention. This study investigates the key factors influencing the switching behaviors of mobile payment application through the perspective of the push–pull–mooring framework. Privacy concerns, alternative rewards, and inertia are identified as push, pull, and mooring factors, respectively. The model was tested with 3785 valid responses among Alipay users. Inertia was found to attenuate the relationship between alternative rewards and switching behavior. This study sheds new light on the switching behavior of mobile payment application users. Our findings inform service providers to retain existing users as well as attract potential users.
