[Tex/LaTex] BibTeX Warning—-empty title

bibtexnatbib

I'm trying to compile my bib references with natbib and \bibliographystyle{nature}. To my uttermost surprise BibTeX reports that some of the entries have an empty title, while IMHO the title is not empty, e.g., on the following bibliographic entries:

@INPROCEEDINGS{WuWangZhaoMa,
author={Wu Kehe and Wang Zhuo and Zhao Xing and Ma Gang},
booktitle={Advanced Computer Theory and Engineering (ICACTE), 2010 3rd International Conference on},
title={Design and implementation of the monitoring system for EJB applications based on interceptors},
year={2010},
month=aug,
volume={4},
pages={V4-5--V4-9},
ISSN={2154-7491},
location = {Chengdu, China}
}

and

@inproceedings{DBLP:conf/sigdoc/TilleyH03,
  author    = {Scott R. Tilley and
               Shihong Huang},
  title     = "A qualitative assessment of the efficacy of {UML} diagrams
               as a form of graphical documentation in aiding program understanding",
  booktitle = {SIGDOC},
  year      = {2003},
  pages     = {184--191},
  ee        = {http://doi.acm.org/10.1145/944868.944908},
  crossref  = {DBLP:conf/sigdoc/2003},
  bibsource = {DBLP, http://dblp.uni-trier.de}
}
@proceedings{DBLP:conf/sigdoc/2003,
  editor    = {Susan B. Jones and
               David G. Novick},
  title     = {Proceedings of the 21st annual international conference
               on Documentation, SIGDOC 2003, San Francisco, CA, USA, October
               12-15, 2003},
  booktitle = {SIGDOC},
  publisher = {ACM},
  year      = {2003},
  isbn      = {1-58113-696-X},
  bibsource = {DBLP, http://dblp.uni-trier.de}
}

Best Answer

According to the documentation of natbib, the following could be sufficient to get a style similar to what Nature uses:

\usepackage[super]{natbib}
\bibpunct{}{}{,}{s}{}{\textsuperscript{,}}
\renewcommand\bibnumfmt[1]{#1.}

and then

\bibliographystyle{plainnat}

Other possibilities are unsrtnat or naturemag in place of plainnat.
