词霸
jieba 标记符号转换器可将中文文本分解为单词。
jieba 令牌转换器在输出中保留标点符号作为独立令牌。例如,"你好!世界。" 变成["你好", "!", "世界", "。"] 。要删除这些独立的标点符号,请使用 removepunct过滤器。
配置
Milvus 支持jieba 令牌生成器的两种配置方法:简单配置和自定义配置。
简单配置
使用简单配置,只需将标记符设置为"jieba" 。例如
# Simple configuration: only specifying the tokenizer name
analyzer_params = {
"tokenizer": "jieba", # Use the default settings: dict=["_default_"], mode="search", hmm=True
}
Map<String, Object> analyzerParams = new HashMap<>();
analyzerParams.put("tokenizer", "jieba");
const analyzer_params = {
"tokenizer": "jieba",
};
analyzerParams = map[string]any{"tokenizer": "jieba"}
# restful
analyzerParams='{
"tokenizer": "jieba"
}'
此简单配置等同于以下自定义配置:
# Custom configuration equivalent to the simple configuration above
analyzer_params = {
"type": "jieba", # Tokenizer type, fixed as "jieba"
"dict": ["_default_"], # Use the default dictionary
"mode": "search", # Use search mode for improved recall (see mode details below)
"hmm": True # Enable HMM for probabilistic segmentation
}
Map<String, Object> analyzerParams = new HashMap<>();
analyzerParams.put("type", "jieba");
analyzerParams.put("dict", Collections.singletonList("_default_"));
analyzerParams.put("mode", "search");
analyzerParams.put("hmm", true);
// javascript
analyzerParams = map[string]any{"type": "jieba", "dict": []any{"_default_"}, "mode": "search", "hmm": true}
# restful
有关参数的详细信息,请参阅自定义配置。
自定义配置
为获得更多控制权,您可以提供自定义配置,允许您指定自定义字典、选择分割模式以及启用或禁用隐马尔可夫模型(HMM)。例如
# Custom configuration with user-defined settings
analyzer_params = {
"tokenizer": {
"type": "jieba", # Fixed tokenizer type
"dict": ["customDictionary"], # Custom dictionary list; replace with your own terms
"mode": "exact", # Use exact mode (non-overlapping tokens)
"hmm": False # Disable HMM; unmatched text will be split into individual characters
}
}
Map<String, Object> analyzerParams = new HashMap<>();
analyzerParams.put("tokenizer", new HashMap<String, Object>() {{
put("type", "jieba");
put("dict", Arrays.asList("customDictionary"));
put("mode", "exact");
put("hmm", false);
}});
// javascript
analyzerParams := map[string]interface{}{
"tokenizer": map[string]interface{}{
"type": "jieba",
"dict": []string{"customDictionary"},
"mode": "exact",
"hmm": false,
},
}

布尔标志,表示是否启用隐马尔可夫模型(HMM)对字典中找不到的单词进行概率分割。 |

定义analyzer_params 后,您可以在定义 Collections Schema 时将其应用到VARCHAR 字段。这样,Milvus 就能使用指定的分析器对该字段中的文本进行处理,以实现高效的标记化和过滤。有关详情,请参阅示例使用。
示例
在将分析器配置应用到 Collections 模式之前,请使用run_analyzer 方法验证其行为。
