kuromoji_baseform token filter
editkuromoji_baseform token filter
editThe kuromoji_baseform token filter replaces terms with their
BaseFormAttribute. This acts as a lemmatizer for verbs and adjectives. Example:
PUT kuromoji_sample
{
"settings": {
"index": {
"analysis": {
"analyzer": {
"my_analyzer": {
"tokenizer": "kuromoji_tokenizer",
"filter": [
"kuromoji_baseform"
]
}
}
}
}
}
}
POST kuromoji_sample/_analyze
{
"analyzer": "my_analyzer",
"text": "飲み"
}
which responds with:
{
"tokens" : [ {
"token" : "飲む",
"start_offset" : 0,
"end_offset" : 2,
"type" : "word",
"position" : 0
} ]
}
