# kuromoji_part_of_speech token filter [analysis-kuromoji-speech]
|
|
|
|
The `kuromoji_part_of_speech` token filter removes tokens that match a set of part-of-speech tags. It accepts the following setting:
|
|
|
|
`stoptags`
|
|
: An array of part-of-speech tags that should be removed. It defaults to the `stoptags.txt` file embedded in the `lucene-analyzer-kuromoji.jar`.
|
|
|
|
For example:
|
|
|
|
```console
|
|
PUT kuromoji_sample
|
|
{
|
|
"settings": {
|
|
"index": {
|
|
"analysis": {
|
|
"analyzer": {
|
|
"my_analyzer": {
|
|
"tokenizer": "kuromoji_tokenizer",
|
|
"filter": [
|
|
"my_posfilter"
|
|
]
|
|
}
|
|
},
|
|
"filter": {
|
|
"my_posfilter": {
|
|
"type": "kuromoji_part_of_speech",
|
|
"stoptags": [
|
|
"助詞-格助詞-一般",
|
|
"助詞-終助詞"
|
|
]
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}
|
|
|
|
GET kuromoji_sample/_analyze
|
|
{
|
|
"analyzer": "my_analyzer",
|
|
"text": "寿司がおいしいね"
|
|
}
|
|
```
|
|
|
|
Which responds with:
|
|
|
|
```console-result
|
|
{
|
|
"tokens" : [ {
|
|
"token" : "寿司",
|
|
"start_offset" : 0,
|
|
"end_offset" : 2,
|
|
"type" : "word",
|
|
"position" : 0
|
|
}, {
|
|
"token" : "おいしい",
|
|
"start_offset" : 3,
|
|
"end_offset" : 7,
|
|
"type" : "word",
|
|
"position" : 2
|
|
} ]
|
|
}
|
|
```
