Chinese Text Segmentation
Chinese text segmentation, keyword extraction and speech tagging For R.
"结巴"中文分词的R语言版本，支持多种分词模式，同时有词性标注，关键词提取，文本Simhash相似度比较等功能。项目使用了Rcpp和CppJieba进行开发。
细胞词库转换可以使用 cidian 包 ：https://github.com/qinwf/cidian/
特性
- 支持 Windows，Linux，Mac 操作系统。
- 通过 Rcpp 实现同时加载多个分词系统,可以分别使用不同的分词模式和词库。
- 支持多种分词模式、中文姓名识别、关键词提取、词性标注以及文本Simhash相似度比较等功能。
- 支持加载自定义用户词库，设置词频、词性。
- 同时支持简体中文、繁体中文分词。
- 支持自动判断编码模式。
- 比原"结巴"中文分词速度快，是其他R分词包的5-20倍。
- 安装简单，无需复杂设置。
- 可以通过Rpy2，jvmr等被其他语言调用。
- 基于MIT协议。
安装
通过CRAN安装:
install.packages("jiebaR")library("jiebaR") cc = worker()cc["这是一个测试"] # or segment("这是一个测试", cc) # [1] "这是" "一个" "测试"
同时还可以通过Github安装开发版，建议使用 gcc >= 4.9 编译，Windows需要安装 Rtools ：
library(devtools)install_github("qinwf/jiebaRD")install_github("qinwf/jiebaR")library("jiebaR")

and speech tagging. jiebaR supports four
types of segmentation modes: Maximum Probability, Hidden Markov Model, Query Segment and Mix Segment.
Features
- Support Windows, Linux,and Mac.
- Using Rcpp to load different segmentation worker at the same time.
- Support Chinese text segmentation, keyword extraction, speech tagging and simhash computation.
- Custom dictionary path.
- Support simplified Chinese and traditional Chinese.
- New words identification.
- Auto encoding detection.
- Fast text segmentation.
- Easy installation.
- MIT license.

News
Changes in Version 0.9.1 (2016-9-28)
o Major Change: distance and vector_distance now return integer value as distance.
o Major Change: requires C++11 with GCC 4.9+ to build this package
o Fix: tobin now returns the correct value
o Fix: get_idf rownames with 1 based index
o Add: new_user_word now has a default tag
o Add: apply_list to handle nested list input data
o Add: simhash_dist to compute distance of simhash values
o Add: simhash_dist_mat to compute compute distance matrix of simhash values
o Add: vector_tag to tag a character vector
o Add: more docs
o Depreciated: quick mode will be remove in v0.11.0
o Depreciated: filecoding to file_coding
o Warning: next version will update internal CppJieba version to 5.0.0, query_threshold, words_locate will be removed due to the upstream apis changes.
Changes in Version 0.8.2 (2016-4-18)
o Add: user_weight option for worker(), and default value is the max weight. o Fix: Build with R 3.3.0
Changes in Version 0.8 (2016-1-14)
o Remove: ShowDictPath() EditDict() tag() o Remove: some C API due to CppJieba V4.4.1 update.
o C APIs will not work: jiebaR_mp_ptr jiebaR_mp_cut jiebaR_query_ptr jiebaR_query_cut jiebaR_hmm_ptr jiebaR_hmm_cut.
o C APIs will work but give a warning: jiebaR_mix_ptr jiebaR_mix_cut jiebaR_tag_ptr jiebaR_tag_tag jiebaR_tag_file. jiebaR_mix_cut.
o C APIs change: jiebaR_key_ptr jiebaR_sim_ptr add user path varible.
o Add: some C API due to CppJieba V4.4.1 update.
jiebaR_jiebaclass_ptr, jiebaR_jiebaclass_mix_cut, jiebaR_jiebaclass_mp_cut, jiebaR_jiebaclass_hmm_cut, jiebaR_jiebaclass_query_cut, jiebaR_jiebaclass_full_cut, jiebaR_jiebaclass_level_cut, jiebaR_jiebaclass_level_cut_pair, jiebaR_jiebaclass_tag_tag,jiebaR_jiebaclass_tag_file, jiebaR_set_query_threshold, jiebaR_add_user_word, jiebaR_u64tobin, jiebaR_get_loc
