How to use multiple targets in AlchemyAPI targeted sentiment analysis?

When using AlchemyAPI Language for targeted sentiment analysis, the docs indicate that you can specify either target or targets. Specifying targets causes the response to contain an array, however I cannot figure out how to specify multiple targets in a single call.

Specifying a single target (but using the targets parameter):

curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d "text=I love cats. Dogs are the worst." -d "targets=cats" -d "outputMode=json" "https://gateway-a.watsonplatform.net/calls/text/TextGetTargetedSentiment?apikey=MY_API_KEY"

Does the service support multiple targets? And if so, how do I pass them?

Solution

  • The documentation has been updated with the answer to this: http://www.alchemyapi.com/api/sentiment/textc.html#targetedsentiment

    The solution is to use pipe characters: dogs|cats.

    Full example:

    curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d "text=I love cats. Dogs are the worst." -d "targets=cats|dogs"  -d "outputMode=json"    "https://gateway-a.watsonplatform.net/calls/text/TextGetTargetedSentiment?apikey=MY_API_KEY"
