ACM bibtex 格式问题

Question

大家好，我正在使用 ACM 格式（严格遵守 SIGS 样式）来编辑我的 bibtex 文件。现在我遇到了一个奇怪的问题，这是我的代码：

 @INCOLLECTION{Chen06
 AUTHOR = "Chen, Yi-Wei and Lin, Chih-Jen",
 TITLE = "Combining SVMs with Various Feature Selection Strategies",
 BOOKTITLE = {Feature Extraction},
 PUBLISHER = "Springer Berlin Heidelberg",
 PAGES = {315-324},
 YEAR={2006} }

现在，当我使用 BibTex 对其进行处理时，出现以下错误：

 I was expecting a `,' or a `}'---line 262 of file cikmRefs.bib
 : 
 : AUTHOR = "Chen, Yi-Wei and Lin, Chih-Jen",
(Error may have been on previous line)
I'm skipping whatever remains of this entry
Warning--empty author in Chen06
Warning--empty title in Chen06
Warning--empty booktitle in Chen06
Warning--empty publisher in Chen06
Warning--empty year in Chen06

我在“Chen06”后面漏了一个逗号，谢谢大家。另一个问题是编译器给了我以下错误，对应于以下代码：

 @INCOLLECTION{Platt99a,
 AUTHOR = "Platt, John C.",
 CHAPTER = "Fast training of support vector machines using sequential minimal optimization",
 BOOKTITLE = {Advances in kernel methods},
 PUBLISHER = "MIT Press",
 ADDRESS = "Cambridge, MA, USA",
 YEAR = {1999}  } 

 Warning--empty title in Platt99a

我没有发现我的代码有任何问题。
