摘要：The integration of the two fast-developing scientific research areas Semantic Web and Web mining is known as Semantic Web mining. The huge increase in the amount of Semantic Web data became a perfect target for many researchers to apply Data mining techniques on it. This paper gives a detailed state-of-the-art survey of on-going research in this new area. It shows the positive effects of Semantic Web mining, the obstacles faced by researchers and propose number of approaches to deal with the very complex and heterogeneous information and knowledge which are produced by the technologies of Semantic Web.

摘要：Microbial cell factories (MCFs) are typical and widely used platforms in biomanufacturing for designing and constructingsynthesis pathways of target compounds in microorganisms. In MCFs, transporter engineering is especially significant forimproving the biomanufacturing efficiency and capacity through enhancing substrate absorption, promoting intracellular masstransfer of intermediate metabolites, and improving transmembrane export of target products. This review discusses thecurrent methods and strategies of mining and characterizing suitable transporters and presents the cases of transporterengineering in the production of various chemicals in MCFs.

摘要：Taking landscape design of the former area in Wangfenggang coal mine of Anhui Huainan as an example,the whole thinking and specific implementations were discussed from aspects including scenic spot planning,plant landscape and characteristics of scenic spots,and created landscape in mining areas,squares and residential districts by combining section peculiarity,old building characteristics and circumstance in the landscape design of mining areas,which aimed to realize sustainable development of landscape in mining areas.

摘要：In very short time today web has become an enormously important tool for communicating ideas, conducting business and entertainment. At the time of navigation, web users leave various records of their action. This vast amount of data can be a useful source of knowledge for predicting user behavior. A refined method is required to carry out this task. Web usages mining (WUM) is the tool designed to do this task. WUM system is used to extract the knowledge based on user behavior during the web navigation. The extracted knowledge can be used for predicting the users’ future request when user is browsing the web. In this paper we advanced the online recommender system by using a Longest Common Subsequence (LCS) classification algorithm to classify users’ navigation pattern. Classification using the proposed method can improve the accuracy of recommendation and also proposed an algorithm that uses LCS method to know the user behavior for improvement of design of a website.

摘要：随着旅游业和互联网融合的不断加深,网络信息已经成为游客感知研究的重要数据来源。将南靖土楼景区游客发布的感知信息作为分析样本,运用ROST Content mining软件挖掘出游记中的高频词,建立分析类目,分析旅游吸引物、旅游配套、景区管理、景区感知、旅游环境五个主类目对应的游客感知,以此为基础,从吃、住、行、游、购、娱六个方面对田螺坑景区的旅游产品设计与改进提出建议。

摘要：数据挖掘扩展插件DMX(Data mining eXtension)语言是由微软提出的在SSAS(SQLServer Analysis Services)中实现的符合OLE DB for Data mining规范的数据挖掘语言,它提供了创建、访问和管理数据挖掘算法和信息的数据存储方式和开源的可扩展的模型调用体系。为了满足目前国内中小企业迫切需求的数据挖掘工具的应用需求,通过分层设计、逐次封装,设计并实现了一种基于DMX语言的特性和功能并具有平台无关性和应用推广性的数据挖掘算法包原型系统。通过公共测试数据验证了该原型系统的可行性和可用性。
