title: Bing/Google/Flickr API: how would you find an image to go along each of 150,000 Japanese sentences?
body: <p>I'm doing part-of-speech &amp; morphological analysis project for Japanese sentences. Each sentence will have its own webpage. To make this page more visual, I want to show one picture which is somehow related to the sentence. For example, For the sentence "私は学生です"　（"I'm a student"), the relevant pictures would be pictures of school, Japanese textbook, students, etc. What I have: part-of-speech tagging for every word. My approach now: use 2-3 nouns from every sentence and retrieve the first image from search results using Bing Images API. Note: all the sentence processing up to this point was done in Java. </p>

  <p>Have a couple of questions though:
  1) what is better (richer corpus &amp; powerful search), Google Images API, Bing Images API, Flickr API, etc. for searching nouns in Japanese? 
  2) how do you select the most important noun from the sentence to do the query in Image Search Engine without doing complicated topic modeling, etc.?
  Thanks!</p>
