本文主要探讨语言数据学所带来的认知更新及其理论内涵。本文先简要回顾数据学和语言数据研究概况，接着阐释有关语言数据学的五个核心问题：语言数据学的学科本质、语言数据学提出的理论考虑、分支学科建立的必然性、语言数据学所带来的认知更新及其理论内涵。最后聚焦讨论：1）语言数据学更新了现代语言学对于语言与数据间理论关系和“语言数据”之概念本质的基本认知。2）从五个维度阐释了语言数据学的主要理论内涵。

This paper mainly explores the cognitive renewal linguistic data science brings to linguistic inquiry and its theoretical connotations. Building on a concise overview of dataology and existing language data studies, this paper focuses on the discussion of five core issues concerning language data science: the theoretical nature of language data science as a subdiscipline, theoretical considerations underlying its disciplinary construction, the theoretical necessity of introducing this subdiscipline into the academic field, the cognitive renewal it introduces to linguistic inquiry, and its theoretical connotations. In brief, this paper primarily addresses two central issues: First, language data science reshapes modern linguistic understandings of the relationship between language and data, as well as the conceptual nature of “language data”. Second, grounded in a reconceptualization of “language data”, this paper outlines the major theoretical connotations of Language Data Science from five dimensions.
