How to guess a relevant image corresponding to a text (a news title) via machine learning.

I am looking for an algorithm which basically takes input in the form of a text and then returns an image related to the text, by searching on the web. Procedure could be described as follows

• Extracts keywords from the text string

• Search for the keywords on google images, and get the most relevant image for the keywords

• Decide which is the most relevant image out of the ones extracted in the last step and return it.

• I am basically looking for some work already done in this field, otherwise I could start making my own thing now that I am learning machine learning.

So if you know of any such thing, please cite it in the comments below. :) Even great if you could give me pointers to do such a thing on my own.
