'Automatically extract a bibitem in LaTex

I am writing a conference paper in which I am required to use the format \bibitem entries rather than a BibTeX file for the references. Google Scholar support BibTeX. Is there an automatic method or a tool to extract \bibitem?

Example: I have the references in BibTeX format as follow:

 @article{rieck2011similarity,
  title={Similarity measures for sequential data},
  author={Rieck, Konrad},
  journal={Wiley Interdisciplinary Reviews: Data Mining and Knowledge Discovery},
  volume={1},
  number={4},
  pages={296--304},
  year={2011},
  publisher={Wiley Online Library}
}

and I want to convert BibTeX format into the following format (\bibitem):

\bibitem{rieck2011similarity} K.~Rieck, \emph{Similarity measures for sequential data},\hskip 1em plus 0.5em minus 0.4em\relax Wiley Interdisciplinary Reviews: Data Mining and Knowledge Discovery, 2011.
latex


Solution 1:[1]

Since there is no other answer, this (not exactly automatic) way could be helpful :

  • Create a *.tex file with your bibliography in BibTeX
  • Compile as usual (latex/bibtex/latex)
  • In the directory of the *.tex file, open the *.bbl : all citations are converted in bibitem.
  • Copy/paste in your document

I created this online bibtex converter, so it could convert your BibTeX text or file to bibitem.

Example:

 @article{rieck2011similarity,
  title={Similarity measures for sequential data},
  author={Rieck, Konrad},
  journal={Wiley Interdisciplinary Reviews: Data Mining and Knowledge Discovery},
  volume={1},
  number={4},
  pages={296--304},
  year={2011},
  publisher={Wiley Online Library}
}

BibItem output

\bibitem{rieck2011similarity}Rieck, K. Similarity measures for sequential data. {\em Wiley Interdisciplinary Reviews: Data Mining And Knowledge Discovery}. \textbf{1}, 296--304 (2011)

Well, I used this matlab function to convert it automatically one by one, its more easy to get the job done. You can download it from GitHub, and here is the matlab function as the following. 

function [bibitem] = bibtex2bibitem(bibtexpath)
path = bibtexpath;
cells = importdata(path);
A = string(cells);
n = length(cells);
K_name = strings(n,1);
citecode = extractBetween(A(1),'{',',');

for i = 2:1:n-1
        rawleft = extractBefore(A(i),'=');
        K_name(i) = strtrim(rawleft);

%--------------------------------------------------------------------
        if strcmp(K_name(i),"author")
            SVacI(1) = 1;
            rawright = extractAfter(A(i),'=');
            ccb = regexp(rawright,'}');     % ccb = [check curly bracket]
            if (ccb~=0)
                author = strtrim(extractBetween(A(i),'{','}'));
            else 
                author = strtrim(extractBetween(A(i),'=',','));
            end 

%--------------------------------------------------------------------         
        elseif strcmp(K_name(i),"title")
            SVacI(2) = 1;
            rawright = extractAfter(A(i),'=');
            ccb = regexp(rawright,'}');     % ccb = [check curly bracket]
            if (ccb~=0)
                title = strtrim(extractBetween(A(i),'{','}'));
            else 
                title = strtrim(extractBetween(A(i),'=',','));
            end
