I'm trying to get similar results with Watson Alchemy Sentiment API for Spanish sentences compared to translation results in English.
Here's the phrase (actually is a tweet translated from spanish)
"Lower tax revenues and increase electricity subsidy costs = disaster formula"
This is the result from Alchemy Sentiment Score negative -0.74192
Now same sentence but in Spanish (this is the original one)
Bajar ingresos por impuestos y aumentar gastos con subsidio eléctrico = fórmula de desastre
<docSentiment>
<type>neutral</type>
</docSentiment>
What can be done to improve this, thanks for your help.
