Alin: improving interactive ontology matching by interactively revising mapping suggestions

Ontology matching aims at discovering mappings between the entities of two ontologies. It plays an important role in the integration of heterogeneous data sources that are described by ontologies. Interactive ontology matching involves domain experts in the matching process. In some approaches, the expert provides feedback about mappings between ontology entities, that is, these approaches select mappings to present to the expert who replies which of them should be accepted or rejected, so taking advantage of the knowledge of domain experts towards finding an alignment. In this paper, we present Alin, an interactive ontology matching approach which uses expert feedback not only to approve or reject selected mappings but also to dynamically improve the set of selected mappings, that is, to interactively include and to exclude mappings from it. This additional use for expert answers aims at increasing in the benefit brought by each expert answer. For this purpose, Alin uses four techniques. Two techniques were used in the previous versions of Alin to dynamically select concept and attribute mappings. Two new techniques are introduced in this paper: one to dynamically select relationship mappings and another one to dynamically reject inconsistent selected mappings using anti-patterns. We compared Alin with state-of-the-art tools, showing that it generates alignment of comparable quality.

Upgrading Development and Application of Agricultural Information Service System Based on WeChat Public Platform— —A Case of WeChat Public Platform of 12396 Beijing new rural sci-tech service hotline

The WeChat public platform is a new service platform based on WeChat applications that provides business services and user management for individuals, businesses and organizations. It provides a new solution to the lag of agricultural information dissem-ination in the traditional media. However, services based on Tencent's backend can only meet the basic needs of users and reduce the user's experience in agricultural science and technology consulting process. In order to provide efficient and convenient service to users and solve existing problems in consultation process, the platform-related API were used to upgrade the 12396 hotline WeChat public platform to an integrated agricultural information interactive service system. It mainly carries out the following three aspects to upgrade development. Firstly, 12396 hotline WeChat public platform added two sub-menu items, “use ask” and “expert answer” to push the user’s question to expert directly, reducing the backend customer service’s works and improving the efficiency of problem solving. Secondly, 12396 WeChat public platform upgraded and developed an integrated "one-stop" micro-site to allow users know the agriculture market timely, releasing supply and demand information, etc. Thirdly, the 12396 WeChat public platform combined initiative push information with the user's automatic acquisition of information by sending keywords which increased user selectivity. The upgraded platform has obtained a good preliminary application achievement and recognized and welcomed by users. Finally, we concluded and looked forward to the future development direction of agricultural mobile consulting.

The Design of “The Use and Maintenance of Common Digital Products” Popular Science Website

With the development of technology and the improvement of people’s living standard, more and more people purchase digital products, a multimedia website becomes an important way for people to learn how to use and maintain the digital products. The demand for knowledge about digital products use and maintenance was identified by questionnaire and interview, and then the popular science website was designed and made. From the paper, you can learn the design principles of the popular science website: properly selecting contents, using multimedia technology, clear navigation and easy to be used. This website contains the modules of computer, mobile phone, camera, DV, MP4, expert answer and forum, you can learn the basic modules and functions design, and the technical key points of implementation of the popular science website in the paper.
