基于统一搜索的信息服务平台

针对目前多数IT系统的信息服务只具备简单数据查询且资源定位能力薄弱的现状,本文对现有信息服务模式进行了分析,提出了基于信息集成的统一搜索模式。本模式主要包括两部分内容。第一,通过信息集成将分布式异构数据进行提炼、转换和汇总,形成数据全集做为信息源。第二,基于互联网搜索引擎模式和Compass搜索框架,将不同类型、不同粒度和不同主题的信息以统一的方式检索与展示。它的优势在于实现了多种数据源的应用整合并提高了系统可扩展性,更为重要的是极大地提升了用户的信息定位能力,使其获得类似百度或谷歌的使用体验。此模式已被成功应用于中国科学院十一五信息化项目信息管理与服务平台的开发中,获得了良好的应用效果。

Information Service Platform Based on Unified Search

Nowadays,most of IT information service system are lack of resources localization ability and only provide simple data query.Therefore,I analyse the drawback in the current information service models,and propose unified search structure based on information integration framework to improve information search quality.This model consists of two components.Firstly,in order to form data collection as the source of information,distributed heterogeneous data is extracted,transformed and aggregated by the information integration module.Secondly,according to Internet Search Engine model and COMPASS framework,different types,size and themes data is queried and displayed in a unified way.This enhances system information integration capabilities and shows powerful expansibility.What is more important is our proposed system extremely promotes user’s information localization ability and using experience as Baidu or Google.Finally,this model is successfully applied to the information management and service platform development,which is one of the Eleventh Five-year informationization projects of Chinese Academy of Sciences.
