"結巴"中文分詞：做最好的 PHP 中文分詞、中文斷詞組件，目前翻譯版本為 jieba-0.33 版本，未來再慢慢往上升級，效能也需要再改善，請有興趣的開發者一起加入開發！若想使用 Python 版本請前往 fxsjy/jieba

現在已經可以支援繁體中文！只要將字典切換為 big 模式即可！

Feature

  • 支持三種分詞模式：

  • 1）默認精確模式，試圖將句子最精確地切開，適合文本分析；

  • 2）全模式，把句子中所有的可以成詞的詞語都掃描出來，但是不能解決歧義。（需要充足的字典）

    1. 搜尋引擎模式，在精確模式的基礎上，對長詞再次切分，提高召回率，適合用於搜尋引擎分詞。

  • 支持繁體斷詞

  • 支持自定義詞典

Usage

  • 自動安裝：使用 composer 安裝後，透過 autoload 引用

代碼示例

composer require fukuball/jieba-php:dev-master

代碼示例

require_once "/path/to/your/vendor/autoload.php";
  • 手動安裝：將 jieba-php 放置適當目錄後，透過 require_once 引用

代碼示例

require_once "/path/to/your/vendor/multi-array/MultiArray.php";
require_once "/path/to/your/vendor/multi-array/Factory/MultiArrayFactory.php";
require_once "/path/to/your/class/Jieba.php";
require_once "/path/to/your/class/Finalseg.php";

Algorithm

  • 基於 Trie 樹結構實現高效的詞圖掃描，生成句子中漢字所有可能成詞情況所構成的有向無環圖（DAG)
  • 採用了動態規劃查找最大概率路徑, 找出基於詞頻的最大切分組合
  • 對於未登錄詞，採用了基於漢字成詞能力的 HMM 模型，使用了 Viterbi 算法
  • BEMS 的解釋 fxsjy/jieba#7

Interface

  • 組件只提供 jieba.cut 方法用於分詞
  • cut 方法接受兩個輸入參數: 1) 第一個參數為需要分詞的字符串 2）cut_all 參數用來控制分詞模式
  • 待分詞的字符串可以是 utf-8 字符串
  • jieba.cut 返回的結構是一個可迭代的 array

功能 1)：分词

  • cut 方法接受想個輸入參數： 1) 第一個參數為需要分詞的字符串 2）cut_all 參數用來控制分詞模式
  • cutForSearch 方法接受一個參數：需要分詞的字符串，該方法適合用於搜索引擎構建倒排索引的分詞，粒度比較細
  • 注意：待分詞的字符串是 utf-8 字符串
  • cut 以及 cutForSearch 返回的結構是一個可迭代的 array

代碼示例 (Tutorial)

ini_set('memory_limit', '1024M');

require_once "/path/to/your/vendor/multi-array/MultiArray.php";
require_once "/path/to/your/vendor/multi-array/Factory/MultiArrayFactory.php";
require_once "/path/to/your/class/Jieba.php";
require_once "/path/to/your/class/Finalseg.php";
use Fukuball\Jieba\Jieba;
use Fukuball\Jieba\Finalseg;
Jieba::init();
Finalseg::init();

$seg_list = Jieba::cut("怜香惜玉也得要看对象啊！");
var_dump($seg_list);

$seg_list = Jieba::cut("我来到北京清华大学", true);
var_dump($seg_list); #全模式

$seg_list = Jieba::cut("我来到北京清华大学", false);
var_dump($seg_list); #默認精確模式

$seg_list = Jieba::cut("他来到了网易杭研大厦");
var_dump($seg_list);

$seg_list = Jieba::cutForSearch("小明硕士毕业于中国科学院计算所，后在日本京都大学深造"); #搜索引擎模式
var_dump($seg_list);

Output:

array(7) {
  [0]=>
  string(12) "怜香惜玉"
  [1]=>
  string(3) "也"
  [2]=>
  string(3) "得"
  [3]=>

(此處，“杭研“並沒有在詞典中，但是也被 Viterbi 算法識別出來了)

Search Engine Mode:
array(18) {

  [15]=>
  string(6) "大学"
  [16]=>
  string(18) "日本京都大学"
  [17]=>
  string(6) "深造"
}

功能 2)：添加自定義詞典

  • 開發者可以指定自己自定義的詞典，以便包含 jieba 詞庫裡沒有的詞。雖然 jieba 有新詞識別能力，但是自行添加新詞可以保證更高的正確率

  • 用法： Jieba::loadUserDict(file_name) # file_name 為自定義詞典的絕對路徑

  • 詞典格式和 dict.txt 一樣，一個詞佔一行；每一行分為三部分，一部分為詞語，一部分為詞頻，一部分為詞性，用空格隔開

  • 範例：

    云计算 5 n 李小福 2 n 创新办 3 n

    之前： 李小福 / 是 / 创新 / 办 / 主任 / 也 / 是 / 云 / 计算 / 方面 / 的 / 专家 / 加載自定義詞庫後：　李小福 / 是 / 创新办 / 主任 / 也 / 是 / 云计算 / 方面 / 的 / 专家 /

說明："通过用户自定义词典来增强歧义纠错能力" --- fxsjy/jieba#14

功能 3)：關鍵詞提取

  • JiebaAnalyse::extractTags($content, $top_k)
  • content 為待提取的文本
  • top_k 為返回幾個 TF/IDF 權重最大的關鍵詞，默認值為 20
  • 可使用 setStopWords 增加自定義 stop words

代碼示例 (關鍵詞提取)

ini_set('memory_limit', '600M');

require_once "/path/to/your/vendor/multi-array/MultiArray.php";
require_once "/path/to/your/vendor/multi-array/Factory/MultiArrayFactory.php";

Finalseg::init();
JiebaAnalyse::init();

$top_k = 10;
$content = file_get_contents("/path/to/your/dict/lyric.txt", "r");

$tags = JiebaAnalyse::extractTags($content, $top_k);

var_dump($tags);

JiebaAnalyse::setStopWords('/path/to/your/dict/stop_words.txt');

Online Demo

Feature

  • Support three types of segmentation mode:
    1. Accurate Mode, attempt to cut the sentence into the most accurate segmentation, which is suitable for text analysis;
    1. Full Mode, break the words of the sentence into words scanned
    1. Search Engine Mode, based on the Accurate Mode, with an attempt to cut the long words into several short words, which can enhance the recall rate

Usage

  • Installation: Use composer to install jieba-php, then require the autoload file to use jieba-php.

Algorithm

  • Based on the Trie tree structure to achieve efficient word graph scanning; sentences using Chinese characters constitute a directed acyclic graph (DAG).
  • Employs memory search to calculate the maximum probability path, in order to identify the maximum tangential points based on word frequency combination.
  • For unknown words, the character position HMM-based model is used, using the Viterbi algorithm.
  • The meaning of BEMS fxsjy/jieba#7.

Interface

  • The cut method accepts two parameters: 1) first parameter is the string to segmentation 2）the second parameter cut_all to control segmentation mode.
  • The string to segmentation may use utf-8 string.
  • cutForSearch accpets only on parameter: the string that requires segmentation, and it will cut the sentence into short words
  • cut and cutForSearch return an segmented array.

Function 1) Segmentation

Example (Tutorial)

ini_set('memory_limit', '1024M');

require_once "/path/to/your/vendor/multi-array/MultiArray.php";
require_once "/path/to/your/vendor/multi-array/Factory/MultiArrayFactory.php";
require_once "/path/to/your/class/Jieba.php";
require_once "/path/to/your/class/Finalseg.php";
use Fukuball\Jieba\Jieba;
use Fukuball\Jieba\Finalseg;
Jieba::init();
Finalseg::init();

$seg_list = Jieba::cut("怜香惜玉也得要看对象啊！");
var_dump($seg_list);

seg_list = jieba.cut("我来到北京清华大学", true)
var_dump($seg_list); #全模式

seg_list = jieba.cut("我来到北京清华大学", false)
var_dump($seg_list); #默認精確模式

seg_list = jieba.cut("他来到了网易杭研大厦")
var_dump($seg_list);

seg_list = jieba.cut_for_search("小明硕士毕业于中国科学院计算所，后在日本京都大学深造") #搜索引擎模式
var_dump($seg_list);

Output:

array(7) {
  [0]=>
  string(12) "怜香惜玉"
  [1]=>
  string(3) "也"
  [2]=>
  string(3) "得"
  [3]=>
  string(3) "要"
  [4]=>
  string(3) "看"
  [5]=>
  string(6) "对象"
  [6]=>
  string(3) "啊"
}

Full Mode:
array(15) {
  [0]=>
  string(3) "我"
  [1]=>
  string(3) "来"
  [2]=>
  string(6) "来到"
  [3]=>
  string(3) "到"
  [4]=>
  string(3) "北"
  [5]=>
  string(6) "北京"
  [6]=>
  string(3) "京"
  [7]=>
  string(3) "清"
  [8]=>
  string(6) "清华"
  [9]=>
  string(12) "清华大学"
  [10]=>
  string(3) "华"
  [11]=>
  string(6) "华大"
  [12]=>
  string(3) "大"
  [13]=>
  string(6) "大学"
  [14]=>
  string(3) "学"
}

Default Mode:
array(4) {
  [0]=>
  string(3) "我"
  [1]=>
  string(6) "来到"
  [2]=>
  string(6) "北京"
  [3]=>
  string(12) "清华大学"
}
array(6) {
  [0]=>
  string(3) "他"
  [1]=>
  string(6) "来到"
  [2]=>
  string(3) "了"
  [3]=>
  string(6) "网易"
  [4]=>
  string(6) "杭研"
  [5]=>
  string(6) "大厦"
}
(此處，“杭研“並沒有在詞典中，但是也被 Viterbi 算法識別出來了)

Search Engine Mode:
array(18) {
  [0]=>
  string(6) "小明"
  [1]=>
  string(6) "硕士"
  [2]=>
  string(6) "毕业"
  [3]=>
  string(3) "于"
  [4]=>
  string(6) "中国"
  [5]=>
  string(6) "科学"
  [6]=>
  string(6) "学院"
  [7]=>
  string(9) "科学院"
  [8]=>
  string(15) "中国科学院"
  [9]=>
  string(6) "计算"
  [10]=>
  string(9) "计算所"
  [11]=>
  string(3) "后"
  [12]=>
  string(3) "在"
  [13]=>
  string(6) "日本"
  [14]=>
  string(6) "京都"
  [15]=>
  string(6) "大学"
  [16]=>
  string(18) "日本京都大学"
  [17]=>
  string(6) "深造"
}

Function 2) Add a custom dictionary

  • Developers can specify their own custom dictionary to include in the jieba thesaurus. jieba has the ability to identify new words, but adding your own new words can ensure a higher rate of correct segmentation.

  • Usage: Jieba::loadUserDict(file_name) # file_name is a custom dictionary path.

  • The dictionary format is the same as that of dict.txt: one word per line; each line is divided into two parts, the first is the word itself, the other is the word frequency, separated by a space.

  • Example:

    云计算 5 李小福 2 创新办 3

    之前： 李小福 / 是 / 创新 / 办 / 主任 / 也 / 是 / 云 / 计算 / 方面 / 的 / 专家 / 加載自定義詞庫後：　李小福 / 是 / 创新办 / 主任 / 也 / 是 / 云计算 / 方面 / 的 / 专家 /

Function 3) Keyword Extraction

  • JiebaAnalyse::extractTags($content, $top_k)
  • content: the text to be extracted
  • top_k: to return several TF/IDF weights for the biggest keywords, the default value is 20

Example (keyword extraction)

ini_set('memory_limit', '600M');

require_once "/path/to/your/vendor/multi-array/MultiArray.php";
require_once "/path/to/your/vendor/multi-array/Factory/MultiArrayFactory.php";
require_once "/path/to/your/class/Jieba.php";
require_once "/path/to/your/class/Finalseg.php";
require_once "/path/to/your/class/JiebaAnalyse.php";
use Fukuball\Jieba\Jieba;
use Fukuball\Jieba\Finalseg;
use Fukuball\Jieba\JiebaAnalyse;
Jieba::init(array('mode'=>'test','dict'=>'small'));
Finalseg::init();
JiebaAnalyse::init();

$top_k = 10;
$content = file_get_contents("/path/to/your/dict/lyric.txt", "r");

$tags = JiebaAnalyse::extractTags($content, $top_k);

var_dump($tags);

Output:

array(10) {
  ["是否"]=>
  float(1.2196321889395)
  ["一般"]=>
  float(1.0032459890209)

}
