Feature‐Based Relation Classification Using Quantified Relatedness Information

Feature selection is very important for feature‐based relation classification tasks. While most of the existing works on feature selection rely on linguistic information acquired using parsers, this letter proposes new features, including probabilistic and semantic relatedness features, to manifest the relatedness between patterns and certain relation types in an explicit way. The impact of each feature set is evaluated using both a chisquare estimator and a performance evaluation. The experiments show that the impact of relatedness features is superior to existing well‐known linguistic features, and the contribution of relatedness features cannot be substituted using other normally used linguistic feature sets.

From application service provision to service-oriented computing: A study of the IT outsourcing evolution

IT outsourcing is not a new concept. Originating from the early 60’s in the form of time sharing, IT outsourcing has evolved to the application service provision (ASP) model, in the late 90’s to pure services in the beginning of the century. Services, and their major representative web services, are actually the next phase of the movement toward Internet-based componentized software, known in the not so distant past as ASP. As the continuous expansion of the Internet and its relating technologies creates new marketing opportunities, traditional monolithic architectures are giving way to service-oriented computing (SOC), the architecture that enables service provision. SOC permits the utilization of large systems which are comprised of self-containing building blocks: services. Services may be made public, searched, reused and combined to form complex business processes while in the same time retaining a significant level of flexibility. Services and SOC have emerged as a response to a fundamental shift in enterprise business culture that started at the late 90’s. Although they are promising as an IT outsourcing enabler, many issues need to be dealt with before they can be considered suitable for wide adoption. These issues are of technological, business, economic and cultural nature and they were also faced by ASPs in the past. It is worth revisiting the successes and failures of the ASP model in order to get a better understanding of the evolving IT outsourcing industry. In this work, we describe the evolution of service provision from its initial form as software application, through the application service provision era and towards the new trend of web services.     

面向工作流的组织记忆描述模型与实现

为在知识密集型工作流中捕获组织中的知识或信息并嵌入到流程中，提出了一种面向工作流的组织记忆描述模型，设计了基于本体的组织记忆描述模型到面向对象模型的映射器，在此基础上给出了面向工作流组织记忆的实现框架。它根据工作流上下文获取支持信息，支持对语义Web内容的集成，并提供了易于被现有工作流开发人员使用和掌握的工具包，因此提高了上下文感知能力、集成性和可用性。     

智能流程应用模式下基于流程语义库的需求获取

为自动生成满足用户需求的个性化流程,在给出智能流程应用模式的基础上,提出一种用户个性化需求获取新方法。对业务流程中活动进行归纳和抽象,定义一种新服务——元服务,并由元服务组成流程语义库,然后基于流程语义库,提出一种用户需求获取算法,帮助用户快速准确地输入需求信息。理论分析和应用表明：算法提高了用户需求获取的准确程度和效率。
