(Via Nathan Torkington) Amazon has added text concordances and statistics to all the books it has full text for. They have the statistically improbable phrases, which work well to tag the book, but they also have reading level, most common words, and even words-per-currency unit. The information is very much a "by the way" side page, and not a primary navigation tool the way "best reviewed", "bestselling", and so on are sort options when viewing book search results.In the near future it can be easily imagined that the "tags" (aka statistically improbable phrases) feeding into the category hierarchy and search results. It would be insightful to try out this text analysis mechanism to assess Amazon’s collaborative filtering, personalization and recommendation features.
