Method for Opinion mining

i am working on my final year project "OPINION MINING" of mobile set. i have gone thr开发者_开发问答ough bin liu's site and hav refered nearly 50 Different papers but all are suggesting different methods and i am not finding a clear cut solution as to how to proceed with opinion mining i.e. steps.

Double propogation method suggested by bing liu is very hard to proceed (as i have to use c# strictly) and the dependency parser "Minipar" which he uses in that method happens to be in .net 2003 m using vs 2008.

can anybody suggest me a simple nlp based method to do opinion mining where i want to do tasks like: 1.feature extraction 2.opinion lexicon creation and opinion extraction 3.opinion orientation 4.summerization 5.searching for opinions

please help me guys i badly require ur help especially from anybody working in this area...

thanx. amey.

you opinion on bing liu's blog is right

what u need to do now is that you have to compile the pdemo.cpp file or if a problem download the exe hosted under the link http://wanghao.name/minipar/pdemo.zip and write c# code to interact with the application "pdemo.exe"

i have done it, its easy and very efficient
