NLU Analyze: does the -1 to 1 Sentiment Score for Keyword/Entity represent Magnitude or Confidence?

Using the NLU Analyze for Entities and Keywords, the response returns the following Sentiment item score: Sentiment score for the concept ranging from -1 to 1. Negative scores indicate negative sentiment, and positive scores indicate positive sentiment.

Does this score represent the magnitude of the positive or negative sentiment (i.e. -.9952 is very negative while -.1301 is sort of negative)? OR Does this score represent the confidence of the positive or negative sentiment (i.e. -.9952 is definitely negative while -.1301 only probably negative)

The score represents the magnitude of the sentiment. In addition to the links you referenced, I found this Redbook on the IBM Watson NLU (Natural Language Understanding) service quite interesting. It is linked off the additional resources in the NLU docs.
