topic detection using cognitive services
Hi all I followed the excellent post by DataChant on text analytics using the Cognitive Services APIs and was wondering if anyone had seen anything on Topic Detection? I have tried unsuccessfully...
- The API is not so new. Last time I tried it (6 months ago), I wasn't sure how to send a POST request with no content, which was required by the API. But now I know how to do it :)
I may share the solution to apply Topic Detection in my Power BI Text Analytics Webinar: https://info.microsoft.com/US-PowerBI-WBNR-FY17-03Mar-09-TextAnalyticsinPowerBI300768_01Registration-ForminBody.html
Update: I am sorry. My answer above is wrong. The POST with the empty content was a showstopper of a different API. The issue with this API is that it returns HTTP 202 with the operation-location header that contains the URL where the answer will be available. Unfortunately, Power Query doesn't support HTTP 202 due to security reasons. According to the dev team, this is by design. The only way you can implement Topic detection is outside Power Query.
