I am currently exploring three services for identifying person's tweets or facebook post's are helpfulness or not:
will I need to write my on wrapper on these services to identify the helpfulness characteristic or is there any other way to just query & get result.
can anyone please guide which service I need to use for this task
Thanks
It all depends on how you define helpfulness. Whether it is in general, or helpful to answering a question etc.
For Personality Insights, have a look at https://www.ibm.com/watson/developercloud/doc/personality-insights/models.html which has all the traits, as well as what they mean. The closest trait to helpfulness is probably Conscientiousness.
