+* 结巴分词(java版) jieba-analysis
+  首先感谢jieba分词原作者[[https://github.com/fxsjy][fxsjy]]，没有他的无私贡献，我们也不会结识到结巴
+  分词，更不会有现在的java版本。
+
+  结巴分词的原始版本为python编写，目前该项目在github上的关注量为170，
+  打星727次（最新的数据以原仓库为准），Fork238次，可以说已经有一定的用户群。
+
+  结巴分词(java版)只保留的原项目针对搜索引擎分词的功能(cut_for_index、cut_for_search)，词性标注，关键词提取没有实现(今后如用到，可以考虑实现)。
+
+* 简介
+** 支持分词模式
+   - Search模式，用于对用户查询词分词
+   - Index模式，用于对索引文档分词
+
+** 特性
+   - 支持多种分词模式
+   - 全角统一转成半角
+   - 用户词典功能
+   - conf 目录有整理的搜狗细胞词库
+   - 因为性能原因，最新的快照版本去除词性标注，也希望有更好的 Pull Request 可以提供该功能。
+
+* 如何获取
+  - 当前稳定版本
+    #+BEGIN_SRC xml
+      <dependency>

+
+    @Test
+    public void testDemo() {
+        JiebaSegmenter segmenter = new JiebaSegmenter();
+        String[] sentences =
+            new String[] {"这是一个伸手不见五指的黑夜。我叫孙悟空，我爱北京，我爱Python和C++。", "我不喜欢日本和服。", "雷猴回归人间。",
+                          "工信处女干事每月经过下属科室都要亲口交代24口交换机等技术性器件的安装工作", "结过婚的和尚未结过婚的"};
+        for (String sentence : sentences) {
+            System.out.println(segmenter.process(sentence, SegMode.INDEX).toString());
+        }
+    }
+  #+END_SRC
+
+* 算法(wiki补充...)
+  - [ ] 基于 =trie= 树结构实现高效词图扫描
+  - [ ] 生成所有切词可能的有向无环图 =DAG=
+  - [ ] 采用动态规划算法计算最佳切词组合
+  - [ ] 基于 =HMM= 模型，采用 =Viterbi= (维特比)算法实现未登录词识别
+
+* 性能评估
+  - 测试机配置
+  #+BEGIN_SRC screen
+    Processor 2 Intel(R) Pentium(R) CPU G620 @ 2.60GHz
+    Memory：8GB
+
+    分词测试时机器开了许多应用(eclipse、emacs、chrome...)，可能
+    会影响到测试速度
+  #+END_SRC
+  - [[src/test/resources/test.txt][测试文本]]
+  - 测试结果(单线程，对测试文本逐行分词，并循环调用上万次)
+    #+BEGIN_SRC screen
+      循环调用一万次
+      第一次测试结果：
