Yahoo Term Extraction
I'm exploring how to improve the relevance of Yahoo Term Extraction API results. My initial question to Yahoo revealed that their system uses a semantic network to relate words and phrases. I'm experimenting with a two-step process: first, extract terms without a query to identify the most relevant term, and second, use that term as a query in a second extraction to refine the results. This might improve relevance, though it doubles the number of API calls. I plan to test this in my DeliTag and AjaxTag applications.
