Estou escrevendo minha tese usando um modelo LaTeX. Quando tentei importar minhas referências, recebi os seguintes erros ao texificar meu arquivo thesis.tex:

? 

Então, como resolver esses avisos e principalmente como resolver o que está faltando \item. Eu sei que o problema deve ocorrer na seção de bibliografia. O conteúdo do meu arquivo bibtex é assim:

@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}
}

Estou usando o seguinte código:

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

Estou usando Winedt 6 e MikTex2.9 x64 e depois de executar o BibTex em 'Tex', os seguintes erros apareceram:

Responder1

Como isso só aconteceu quando você tentou importar suas referências, você deve verificar cuidadosamente seu arquivo BibTeX em busca de conteúdo não compatível com LaTeX. Por exemplo, na citação que você listou, posso ver um URL com $\sim$. Provavelmente isso está causando um problema e precisa ser removido. Tente criar um novo arquivo BibTeX e adicione suas referências uma por uma para verificar qual delas tem problemas e quais não.

Responder2

Você pode tentar algumas coisas:

1) Certifique-se de estar citando corretamente, ou seja \cite{authorlabel}. por exemplo: \cite{Abdessalem10}.

2) Tente colocar seu arquivo .bib no mesmo diretório do arquivo principal e aponte para ele diretamente. por exemplo:

\bibliography{myrefs}

3) Se estiver usando o TeXnicCenter, certifique-se de ter marcado a UsesBibTeXopção nas propriedades do seu projeto.
