**概要 [#p12e6500]
We put forward an optimized method of stock factors prediction model which can be easily
extended to realtime prediction system., based on the new version of Yahoo Financial text board of
2012.11~2013.6 with about 4000 companies. Preceding studies have verified that BBS text can be used to
forecast trade volume and return. On this basis, LSA (Latent Semantic Analysis) and multi-SVM model
are put forward in our framework to improve the accuracy of natural language processing and the
