Hi,
Can you tell how you work out the relevancy rankings for queries to your Wikipedia Fulltext Search.
For example, given the query "hollywood": http://ws.geonames.org/wikipediaSearch?q=hollywood&maxRows=10
Here are the top four geonames.org ranked wikipedia articles:
- West Hollywood, California
- Los Angeles, California
- Lagos
- Hollywood, Los Angeles, California
If I go to the Wikipedia website do a similar search (clicking SEARCH rather than GO) and ignore results that aren't articles about specific place names, then I get the following ranked list:
- Hollywood, Los Angeles, California
- West Hollywood, California
- Hollywood, Portland, Oregon
- Hollywood, Florida
I know how search engines work - documents are ranked with respect to the frequency of the query term. I'm just wondering why your rankings are different to Wikipedia's. Are you calculating word frequency from the full wikipedia article or just a summary? Are you giving more weight to a query term if it occurs in the title of that wiki article?
Just curious...
Thanks
