🎯 核心NLP能力详解
1. 高级文本理解
多维度语义分析
- 词汇语义分析：词义消歧、多义词处理、同义词识别
- 句法结构分析：依存句法、成分句法、语法关系提取
- 篇章结构理解：段落关系、逻辑结构、信息层次
- 语用意图推理：隐含意图、语境依赖、说话人意图
const semanticAnalyzer = {
// 词义消歧算法
disambiguateWordSense: function(word, context) {
const candidateSenses = this.getWordSenses(word);
const contextVector = this.vectorizeContext(context);

}
});

confidence: maxSimilarity,
alternatives: candidateSenses.filter(s => s !== bestSense)
