Elasticsearch之中文分词器插件es-ik的自定义热更新词库

时间：2021-02-17 14:29:23

1：部署 http 服务

在这使用 tomcat7 作为 web 容器，先下载一个 tomcat7，然后上传到某一台服务器上(192.168.80.10)。

再执行以下命令

tar -zxvf apache-tomcat-7.0.73.tar.gz

cd apache-tomcat-7.0.73/webapp/ROOT

vi hot.dic

测试

在这里，我是为了避免跟我的hadoop和spark集群里的端口冲突，将默认的tomcat8080端口，改为8081端口了。

如果，是3台tomcat集群的话，则对应，比如我的192.168.80.10位8081端口，192.168.80.11位8082端口，192.168.80.12位8083端口

验证一下这个文件是否可以正常访问

http://192.168.80.10:8081/zhoulshot.dic

2：修改 ik 插件的配置文件

cd elasticsearch-2.4.3/plugins/ik/config

vi IKAnalyzer.cfg.xml

修改 key=remote_ext_dict 的 entry 中的内容

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE properties SYSTEM "/dtd/properties.dtd">

<comment>IK Analyzer 扩展配置</comment>

<entry key="ext_dict">custom/mydict.dic;custom/single_word_low_freq.dic;custom/zhouls.dic</entry>

<entry key="ext_stopwords">custom/ext_stopword.dic</entry>

<entry key="remote_ext_dict">http://192.168.80.10:8081/zhoulshot.dic</entry>

</properties>

注意：（1）默认是words_location，我这里改为我自己的了。http://192.168.80.10:8081/zhoulshot.dic （自定义词库）

（2）默认是custom/mydict.dic;custom/single_word_low_freq.dic，我这里改为我自己的了。（自定义热更新词库） custom/mydict.dic;custom/single_word_low_freq.dic;custom/zhouls.dic

3：验证

重启 es，会看到如下日志信息，说明远程的词典加载成功了。

执行下面命令查看分词效果

curl 'http://192.168.80.10:9200/zhouls/_analyze?analyzer=ik_max_word&pretty=true' -d'{"text":"桂林山水"}'

正常情况下桂林山水会分为多个词语，但是我们希望 es 把[桂林山水]作为一个完整的词，又不希望重启 es。

这样就需要修改前面的 zhoulshot.dic 文件，增加一个词语[桂林山水]

vi hot.dic

桂林山水

文件保存之后，查看 es 的日志会看到如下日志信息

再执行下面命令查看分词效果

curl 'http://192.168.80.10:9200/zhouls/_analyze?analyzer=ik_max_word&pretty=true' -d'{"text":"桂林山水"}'

到这为止，可以实现动态添加自定义词库实现词库热更新。

==============================================================================

注意：默认情况下，最多一分钟之内就可以识别到新增的词语。

查看 es-ik 插件的源码可以发现

1：部署 http 服务

第一步：下载tomcat压缩包

/dist/tomcat/tomcat-7/v7.0.73/bin/

第二步：上传tomcat压缩包

第六步：进入tomcat安装目录，并初步认识下

[hadoop@HadoopMaster app]$ cd tomcat-7.0.73/

[hadoop@HadoopMaster tomcat-7.0.73]$

在这里，需要，先事先好，在linux下安装好tomcat。并配置好环境变量。不会的，请移步

第七步：进入webapps/ROOT目录下

[hadoop@HadoopMaster tomcat-7.0.73]$cd webapps/

第八步：新建，自定义的热更新词库。如，我这里，是，zhoulshot.dic

[hadoop@HadoopMaster ROOT]$ pwd

/home/hadoop/app/tomcat-7.0.73/webapps/ROOT

[hadoop@HadoopMaster ROOT]$vim zhoulshot.dic

[hadoop@HadoopMaster ROOT]$ cat zhoulshot.dic

-rw-rw-r--. 1 hadoop hadoop 55 Feb 25 19:44 zhoulshot.dic

[hadoop@HadoopMaster ROOT]$

第九步：验证一下这个zhoulshot热更新词文件是否可以正常访问

2：修改 ik 插件的配置文件

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE properties SYSTEM "/dtd/properties.dtd">

<comment>IK Analyzer 扩展配置</comment>

<entry key="ext_dict">custom/mydict.dic;custom/single_word_low_freq.dic;custom/zhouls.dic</entry>

<entry key="ext_stopwords">custom/ext_stopword.dic</entry>

</properties>

修改为

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE properties SYSTEM "/dtd/properties.dtd">

<comment>IK Analyzer 扩展配置</comment>

<entry key="ext_dict">custom/mydict.dic;custom/single_word_low_freq.dic;custom/zhouls.dic</entry>

<entry key="ext_stopwords">custom/ext_stopword.dic</entry>

<entry key="remote_ext_dict">http://192.168.80.10:8081/zhoulshot.dic</entry>

</properties>

3：验证

重启 es，会看到如下日志信息，说明远程的词典加载成功了。

我这里，为了更好地看出效果，在es的安装目录下，bin/elasticsearch这种方式来启动。

正常情况下桂林不雾霾会分为多个词语，但是我们希望 es 把[桂林不雾霾]作为一个完整的词，又不希望重启 es。

这样就需要修改前面的 zhoulshot.dic 文件，增加一个词语[桂林不雾霾]

直接，ctrl + c，终止es进程，再bin/elasticsearch -d

再执行下面命令查看分词效果

[hadoop@HadoopMaster elasticsearch-2.4.3]$curl 'http://192.168.80.10:9200/zhouls/_analyze?analyzer=ik_max_word&pretty=true' -d '{"text":"桂林不雾霾"}'

{

"tokens" : [ {

"token" : "桂林不雾霾",

"start_offset" : 0,

"end_offset" : 5,

"type" : "CN_WORD",

"position" : 0

}, {

"token" : "桂林",

"start_offset" : 0,

"end_offset" : 2,

"type" : "CN_WORD",

"position" : 1

}, {

"token" : "桂",

"start_offset" : 0,

"end_offset" : 1,

"type" : "CN_WORD",

"position" : 2

}, {

"token" : "林",

"start_offset" : 1,

"end_offset" : 2,

"type" : "CN_CHAR",

"position" : 3

}, {

"token" : "不",

"start_offset" : 2,

"end_offset" : 3,

"type" : "CN_CHAR",

"position" : 4

}, {

"token" : "雾",

"start_offset" : 3,

"end_offset" : 4,

"type" : "CN_WORD",

"position" : 5

}, {

"token" : "霾",

"start_offset" : 4,

"end_offset" : 5,

"type" : "CN_WORD",

"position" : 6

} ]

}

[hadoop@HadoopMaster elasticsearch-2.4.3]$

到这为止，可以实现动态添加自定义词库实现词库热更新!

==============================================================================

注意：默认情况下，最多一分钟之内就可以识别到新增的词语。

完毕！
