Project Description:
I have an android application, I get the title of products from web sites and add my arraylist. In total 890 title that I got however some of them are unrelated data, and also it takes long time ( max 5 min) to get all.

1.I have to filter the data by using filtering algorithm ( not directly use because this is my master thesis I have to add some value to the algorithm) In addition,I have thought to add a score of each of them then sort according to this value.

2.I have to decrease the time for example max 1 min.

Could you help me ? Any information is appreciated.
