Twitter data from a crisis that impacted many English–Spanish bilinguals show that the direction of codeswitches is associated with the statistically documented tendency of single speakers to prefer one language over another in their tweets, as gleaned from their tweeting history. Further, lexical diversity, a measure of vocabulary richness derived from information-theoretic measures of uncertainty in communication, is greater in proximity to a codeswitch than in productions remote from a switch. The prospects of a role for lexical diversity in characterizing the conditions for a language switch suggest that communicative precision may induce conditions that attenuate constraints against language mixing.

在线交流对语码转换的洞察：语言偏好和词汇丰富性产生的条件的影响

来自影响许多英语-西班牙语双语者的危机的 Twitter 数据表明，从他们的推文历史中可以看出，从统计上记录的单个说话者在推文中偏爱一种语言而不是另一种语言的趋势与语码转换的方向有关。此外，词汇多样性是一种衡量词汇丰富程度的方法，它是从信息论对交流不确定性的测量中得出的，在靠近语码开关的地方比在远离开关的产品中更大。词汇多样性在表征语言转换条件方面的作用的前景表明，交际精确度可能会导致减弱对语言混合的限制的条件。
