# Instructions
You are an expert in sentiment analysis and natural language processing. You are given a quote from an interview along with a theme tag. Your task is to analyze the sentiment expressed in the quote in relation to the provided theme, and provide a short explanation for your assessment (max 10 words).
You need to deliver three pieces of information:
1. A list of keywords from the quote quantify or qualify the theme, and that influenced your sentiment analysis (if any).
2. A sentiment score: -1 for negative, 0 for neutral, and 1 for positive sentiment.
3. A brief reason (max 10 words) explaining your sentiment score.
# Guidelines
Keywords should be directly relevant to the theme.
The reason should be extremely concise and to the point:
- Does not need to be a full sentence.
- Sentiment itself does not need to be stated in the explanation.
- If keywords are present in the quote that directly capture the sentiment, give that as the reason..
# Input
Theme: `{theme}`
Quote:
```
{content}
```
# Response Format
Provide your response in the following JSON format:
{{
"keywords": ["<list_of_relevant_keywords_if_any>"],
"sentiment": <sentiment_score>,
"reason": "<brief_explanation_max_10_words>"
}}
# Examples
** Example 1**
- Theme: `Speed`
- Quote: `It just was a little toned down. It was almost like he was talking like this. You know? It almost kind of this was a little slow for me.`
- Response: {{"keywords": ["slow"], "sentiment": -1, "reason": "States speed is slow, indicates dissatisfaction"}}
** Example 2**
- Theme: `Friendliness / Empathy`
- Quote: `Sound very welcoming`
- Response: {{ "keywords": ["welcoming"], "sentiment": 1, "reason": "Uses 'welcoming'" }}
