I am writing my thesis using a LaTeX template. When I tried to import my references, I got the following errors when I texifyed my thesis.tex:

? 

So how to solve these warnings and especially how to solve the 'missing \item' one. I know the problem must occurs in the bibliography section. The content of my bibtex file is like:

@article{Abdessalem10,
  author    = {Talel Abdessalem and
               Bogdan Cautis and
               Nora Derouiche},
  title     = {ObjectRunner: Lightweight, Targeted Extraction and Querying
               of Structured Web Data},
  journal   = {PVLDB},
  volume    = {3},
  number    = {2},
  year      = {2010},
  pages     = {1585-1588},
  ee        = {http://www.comp.nus.edu.sg/$\sim$vldb2010/proceedings/files/papers/D18.pdf},
  bibsource = {DBLP, http://dblp.uni-trier.de}
}

I am using the following code:

    \bibliographystyle{aaai}%{CUEPhDbiblio-url}
    \bibliography{12_backmatter/myrefs} % adjust this to fit your BibTex file

I am using Winedt 6 & MikTex2.9 x64, and after I ran BibTex in 'Tex', the following errors popped up:

Command Line:   bibtex.exe "thesis"

The best, and most general, way to find and solve problems like these is by constructing a minimal working example (MWE). You can then edit your question to include it so that others can help you locate and solve the problem(s). –  jon Apr 8 '13 at 16:59
    
I don't think aaai.bst is not a standard file; it would be helpful if you told us where it came from. –  jon Apr 8 '13 at 17:01
    
Welcome to TeX.SX. A tip: If you indent lines by 4 spaces, then they're marked as a code sample. You can also highlight the code and click the "code" button ({}) or hit Ctrl+K. –  Claudio Fiandrino Apr 8 '13 at 17:03
    
It sounds very much like there's a problem with the instruction \bibliography{12_backmatter/myrefs}. Have you checked that (i) your bib file is named myrefs.bib and (ii) that the bib file is located in a subdirectory (relative to your main tex file) named "12_backmatter"? Have you tried moving myrefs.bib to the directory where your main tex file is located and then rerunning latex/bibtex/latex/latex -- this time without the 12_backmatter/ substring in the \bibliography statement? –  Mico Apr 8 '13 at 17:08
    
my bib file is named 'myrefs.bib', and it is located in '12_backmatter', I have checked that. '12_backmatter' is located in the main folder where 'thesis.tex' is placed. –  daiyue Apr 8 '13 at 17:14

Since this only happened when you tried to import your references, you should carefully check your BibTeX file for non-LaTeX friendly content. For example, in the citation you listed, I can see a URL with $\sim$. This is probably causing you a problem and needs to be removed. Try to make a new BibTeX file and add your references one-by-one to check which one has problems and which not.

does it have something to do with the code i am using? like:\bibliographystyle{aaai}%{CUEPhDbiblio-url} \bibliography{12_backmatter/myrefs} % adjust this to fit your BibTex file –  daiyue Apr 8 '13 at 16:54
    
The $\sim$ will not cause a problem from BibTeX's point of view. –  jon Apr 8 '13 at 16:56

I guess the problem maybe that your bibtex compilation didn't generate any correct items, thus the bibliography section is now empty. So, LaTeX think you are trying to create a list environment without any items ... this is what I can guess to the best of my knowledge! –  Bichoy Apr 8 '13 at 16:57

Maybe. It looks to me like he hasn't run bibtex on the file. But the $\sim$ can be put in a bibliography entry just fine, AFAIK (though I wouldn't put one in a URL). –  jon Apr 8 '13 at 17:04

@Bichoy, something (a botched BibTeX run?) did create the file the bibliography is trying to process, probably empty. Or OP did not only add the bibliography, but inadvertently messed up some other environment (yes, I've spent hours looking at the wrong environments, only to find a stupid typo from an editor command getting into the file in some totally unrelated place). –  vonbrand Apr 8 '13 at 17:30

You could try a couple of things:

1) Make sure you are citing correctly, i.e. \cite{authorlabel}. e.g: \cite{Abdessalem10}.

2) Try putting your .bib file in the same directory as your main file, and point to it directly. e.g:

\bibliography{myrefs}

3) If using TeXnicCenter, make sure you have checked the UsesBibTeX option in your project properties.
