基于Web的数学公式检索系统设计与实现

The Design and Implementation of Web-based Formula Retrieval System

数学公式在Web环境下使用得越来越广泛,人们迫切需要通过对数学公式检索来获取相关的信息,但是目前主流的搜索引擎都不能检索数学公式。在分析公式自身特点的基础上提出构造公式索引的一些策略,并结合当前信息检索系统研究的成果,设计并实现了Web环境下的检索数学公式系统。

Formulas are used more and more on the web. Retrieval of formulas is becoming more and more important for those who try to find scientific information. The popular Search Engines, however, fail to search math formulas. On the basis of analysis of mathematic formulas characteristics, we provide some strategies of constructing mathematic index. With the achievement of modem information retrieval tchnology, we design and implement a web -based formulas retrieval system.
