\citetitle{} 无定冠词

Question

我有以下引用：

\citet{vonNeumann1947} introduced expected utility theory, the first fully formalized theory of choice under risk, in their \citetitle{vonNeumann1947}.

定义vonNeumann1947如下

@book{vonNeumann1947,
address = {Princeton},
author = {von Neumann, John and Morgenstern, Oskar},
booktitle = {The Theory of Games and Economic Behavior},
publisher = {Princeton University Press},
title = {{The Theory of Games and Economic Behavior}},
year = {1947}
}

这被渲染biblatex为

von Neumann and Morgenstern (1947) introduced expected utility theory, the first fully formalized theory of choice under risk, in their The Theory of Games and Economic Behavior.

有没有什么方法可以将The书名中的从中删除，\titlecite{}而又不必弄乱.bib文件中的标题？

Answer 1

有了 Biber，一切就变得如此简单

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map[overwrite=false]{
      \step[fieldsource=title, match=\regexp{\AThe\s+(.*)}, final]
      \step[fieldset=shorttitle, fieldvalue={$1}]
    }
  }
}

但因为你在球场周围还有另一副支架，title所以我们需要用稍长一点的

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map[overwrite=false]{
      \step[fieldsource=title, match=\regexp{\AThe\s+(.*)}, final]
      \step[fieldset=shorttitle, fieldvalue={$1}]
    }
    \map[overwrite=false]{
      \step[fieldsource=title, match=\regexp{\A\{The\s+(.*)\}}, final]
      \step[fieldset=shorttitle, fieldvalue=\regexp{{$1}}]
    }
  }
}
