Re: [tagmaps] Re: suggestions for getting original flickr image from tagmaps api


Most of what we do in World Explorer / TagMaps is described in the paper
Shane Ahern, Mor Naaman, Rahul Nair, Jeannie Yang. World Explorer: Visualizing Aggregate Data from Unstructured Text in Geo-Referenced Collections.

Indeed, we do follow step B I listed below, using a "search by relevance and bounding box" to get the photos on the right pane. Yes, it seems to work better than tag search. A lot of it has to do with the bounding box restriction (see the paper "How Flickr Helps Us Make Sense of the World" for some actual evidence that the bounding box improves things).

As to your second question, our related tags are simply the other high-scoring tags in the same bounding box. Yes, using some correlations and better filtering may help!

I was hoping of jumping from (a) to (c) with the specific images that
TagMaps has recognized as relevant to that tag. At least from
appearances in the flash app, it seems that the number (and quality)
of images that appear for a specific tag seem to have been refined
from what I might find by doing a direct tag search via the Flickr
interface. Is this true or are my expectations just lower because I'm
used to unassisted browsing by tags?

In another direction entirely, can you tell me if you do any
correlation between the tags suggested by TagMaps and the tags that
Flickr seems to statistically predict with it's "getRelated" function?
(sorry I would provide the exact url for clarity, but it seems the
interface is down) By this I'm wondering if you leverage the tags
that you've found from one geographical area in TagMaps versus the
tags that may be statistically related to give the smaller list that
appears when I hover over an area. If not, how _do_ you create that
smaller list of suggested tags ;) ?

Thanks again and I look forward to working with this great data.

Eric
