Just came across Managed Q, a search application the inventors describe as “dedicated to helping you manage your entire Search Experience: from the keyword, to results, to previewing, to refinement and repeating with a new query.”
The entity extraction around person, place, and thing seems fairly good. But I’m particularly interested in how you interact with the entities. Just by rolling over any one of them, you can see the precise locations in the found documents where that term appears. Niffty.
Of course, to do this they also only show images of the pages found. That’s right–no text list. Even the paging navigation show thumbnails of the next or previous pages. There are a few interaction problems here and there, but overall it’s quite an interesting experience. I like the thumbnail browse view–it’s helpful for somes types of queries and information seeking.
