Today, with the exponential rise in the use of the internet, the trend of the massive use of mobile devices (tablets, laptops, computers, iPads etc...) the user has become inseparable from his smartphone, which facilitates the use of several services in different fields (work, research, commerce, etc.). Besides, with the proliferation of data, the needs of consumers are becoming increasingly complex. So the composition of web services remains a necessary process allowing to combine several atomic services aggregating different functionalities to answer a complex request. Several techniques in the literature like, AI planning, work flow, Agent, Mathematics and Semantic. These techniques are mainly involved in the automation and improvement of the composition process. In this article, we will survey several context aware web service composition approaches based on these techniques. Remember that the Mobile environment is characterized by software, hardware and space constraints and Web Service Composition in mobile environment must respect these conditions.

移动环境中的 Web 服务组合：技术综述

如今，随着互联网使用的指数级增长，大量使用移动设备（平板电脑、笔记本电脑、电脑、iPad 等...）的趋势，用户已经与智能手机密不可分，智能手机方便了多种设备的使用不同领域的服务（工作、研究、商业等）。此外，随着数据的激增，消费者的需求变得越来越复杂。因此，Web 服务的组合仍然是一个必要的过程，允许组合多个原子服务，聚合不同的功能来响应复杂的请求。文献中的几种技术，如人工智能规划、工作流程、代理、数学和语义。这些技术主要涉及作曲过程的自动化和改进。在本文中，我们将调查几种基于这些技术的上下文感知 Web 服务组合方法。请记住，移动环境的特点是软件、硬件和空间限制，移动环境中的 Web 服务组合必须尊重这些条件。
