宏检索及SDARTS协议探讨

An Introduction to Metasearching and SDARTS Protocol

宏检索的目标是实现跨多个分布式异构数据源的检索,并能对检索结果进行有效整合。SDARTS协议撷取了SDLIP和STARTS两个协议的精华部分,构建了宏检索的基本框架。本文介绍目前宏检索的研究现状,对SDARTS协议的特点及有待完善的地方作一探讨。

SDARTS is a protocol for metasearching over online document collections. It is developed as part of the Digital Libraries Project at the Columbia University Department of Computer Science. The purpose of SDARTS is to make a wide variety of collections with heterogeneous interfaces accessible under one uniform interface. This paper introduces the current research of metasearching, and discusses the characteristics of SDARTS.
