用量化方法揭示阿拉伯应用语言学领域主题高度分散的现状
Thematic Dispersion in Arabic Applied Linguistics: A Bibliometric Analysis using Brookes' Measure
- 采用布罗克斯主题分散度公式分析1564篇文献的主题分布
- 计算得Δ=0.194，表明领域内主题极端分散、缺乏集中焦点
- 方法可复现，适合关注学科结构与演化的研究者参考
本研究运用布罗克斯类别分散度测量法（Δ）分析2019至2025年间1,564篇阿拉伯应用语言学文献的主题结构。这些文献被划分为八个核心子领域，计算得出Δ = 0.194，该极低数值表明该领域呈现显著的主题分散性，反映出强烈的异质性而非集中趋势。研究发现，计算语言学虽占主导地位但未形成霸权，与社会语言学、语言教学等其他子领域共存并持续发展。本文澄清了布罗克斯原始公式的正确使用方式，展示了其在领域特征刻画中的有效性，并提供了一种可复制的文献计量方法，适用于跨领域学科结构评估。
原文摘要 · Abstract (English)
This study applies Brookes' Measure of Categorical Dispersion (Δ) to analyze the thematic structure of contemporary Arabic Applied Linguistics research. Using a comprehensive, real-world dataset of 1,564 publications from 2019 to 2025, classified into eight core sub-disciplines, we calculate a dispersion index of Δ = 0.194. This remarkably low value indicates extreme thematic dispersion, revealing that the field is characterized by pronounced heterogeneity rather than concentration. The analysis identifies Computational Linguistics as a dominant but non-hegemonic force, coexisting with robust research in Sociolinguistics, Language Teaching, and other subfields. This study clarifies the correct application of Brookes' original formula, demonstrates its utility for field characterization, and provides a replicable bibliometric methodology for assessing disciplinary structure across domains.
