I’d just hit “publish” on my last post about the challenges of faceted search for the web when I saw this post from Jeff about Yahoo announced an extension to their public BOSS API that provides “key terms” for search results.
Jeff quotes this excerpt from their description:
Key Terms is derived from a Yahoo! Search capability we refer to internally as “Prisma.”… Key Terms is an ordered terminological representation of what a document is about. The ordering of terms is based on each term’s frequency and its positional and contextual heuristics…Each result contains up to 20 terms describing the document.
Yes, I know, key terms aren’t a faceted classification. And I don’t know what quality or consistency this feature provides. Still, it’s a step towards addressing the first and most serious challenge raised in the Microsoft researchers’ position paper. And it’s nice to see news about Yahoo beyond the saturation coverage of Jerry Yang stepping down.
