词汇内涵的统一特征表示

A Unified Feature Representation for Lexical Connotations

Columbia University(哥伦比亚大学)

Emily Allaway, Kathleen McKeown

摘要:

意识形态的态度和立场往往通过词语和短语的微妙含义来表达。理解这些内涵对于认识说话者的文化和情感观点至关重要。在本文中,我们使用远距离标记来创建一个新的词汇资源表示名词和形容词的内涵方面。我们的分析表明,它与人类的判断非常一致。此外,我们提出了一种方法,用于创建词汇表示,捕获嵌入空间内的内涵,并表明使用嵌入提供了统计上的显着改善的任务时,数据是有限的立场检测。

英文摘要:

Ideological attitudes and stance are often expressed through subtle meanings of words and phrases. Understanding these connotations is critical to recognizing the cultural and emotional perspectives of the speaker. In this paper, we use distant labeling to create a new lexical resource representing connotation aspects for nouns and adjectives. Our analysis shows that it aligns well with human judgments. Additionally, we present a method for creating lexical representations that captures connotations within the embedding space and show that using the embeddings provides a statistically significant improvement on the task of stance detection when data is limited.
