我今天发布了 RMMSeg 0.1.4 版。性能有少许提升，现在使用 ComplexAlgorithm 大约有 20KB/s 的速度，而 SimpleAlgorithm 差不多是 60KB/s 。我在一个 branch 里用 C 来实现了一部分代码，减少了许多 String 的构造，可是效果并不明显，让我非常失望，而且由于我在前一篇 Blog 里提到的 Ruby 关于 Hash 的 Bug ，需要打过 patch 的 Ruby 才能正常运行，所以并没有把带 C 扩展的版本包含在这个 Release 中。

下面是 RubyForge 上的 Release announcement:

rmmseg version 0.1.4 by pluskid http://rmmseg.rubyforge.org

== DESCRIPTION

RMMSeg is an implementation of MMSEG Chinese word segmentation algorithm. It is based on two variants of maximum matching algorithms. Two algorithms are available for using:

* simple algorithm that uses only forward maximum matching. * complex algorithm that uses three-word chunk maximum matching and 3 additonal rules to solve ambiguities.

For more information about the algorithm, please refer to the following essays:

== CHANGES

* Let user store their customized word to Dictionary after loaded. * Improved performance of SimpleAlgorithm.
