Bing Synonyms API Now Available on Windows Azure Marketplace

Bing is making the Synonyms API available for Customer Technical Preview (CTP) in the Windows Azure Marketplace.  The Synonyms API returns alternate references to real world entities like products, people, locations, and more.

For instance, the API intelligently matches the following real world entities to commonly used synonyms:

  • Product synonyms: “Canon 600D” is synonymous with “canon rebel t3i”, etc
  • People synonyms: “Jennifer Lopez”” is synonymous with “jlo”, etc
  • Place synonyms: “Seattle Tacoma International Airport” is synonymous with “sea tac”, etc

These synonyms are mined using data assets gathered by Bing with a measured precision (percentage of correct synonym pairs) of roughly 90%. Knowledge of these entity-synonym pairs can dramatically improve results coverage for product search, local search or people search by mapping the user submitted synonym to the root entity. Results are returned in either XML or JSON. Sign up in the Marketplace today to access the Synonyms API.

During our CTP, developers will have free access to the API up to the monthly cap of 5,000 API calls.  CTP is a public beta for APIs that provides developers with a no-cost opportunity to evaluate the Synonyms API in exchange for providing feedback across a broader set of customer scenarios which Bing will use to improve the accuracy of results and overall performance of the service.

  • Hi there. I just came across this service in the Azure Data Marketplace, and it seems like it may be a great fit for a project I'm working on, but I can't find any information since the CTP announcement. The CTP documentation suggests that there was an aim to release this for broader use last Fall, but I don't see any evidence that this happened.

    So was this project abandoned? Or is this still going to be released at some point?
