Machine learning algorithm
I am looking to research an appropriate algorithm for my purpose, can someone suggest a good learning algorithm for the following scenario:
A user can search for some word in a set of sentences. I will then return the top 10 sentences based on that keyword, I want the algorithm to allow user input, that is a user can click on the best sentences and this information will help the search algorithm to return more appropriate results in the future.
Seems like you want to use user feedback to improve some kind of search results. If that is right you should take a look at Rocchio. You could, also, maintain a list of "clicked" sententes for each keyword. That way you can boost the "clicked" ones positions in the rank.
You might find this chapter in the Qi II manual useful:
6.3 Property Lists
The chapter discusses the use of semantic nets to store and sort data. I also recommend the exercises at the back of the chapter; they may give you some ideas, no matter what language you're writing in.
研究一些矩阵分解技术，如奇异值分解或非负矩阵分解。
