The Sentiment Star Rating System
How SentiSignal converts numeric sentiment scores into an intuitive 1-to-5 star rating for quick visual assessment.
From Numbers to Stars
While the raw sentiment scale (-1.0 to +1.0) is precise, it can be hard to interpret at a glance. That is why SentiSignal converts sentiment scores into a 1-to-5 star rating that appears in asset headers, news cards, and summary widgets. Stars give you an instant visual read on market sentiment.
In the screenshot above you can see the XRP asset header: XRP (XRP) — AI Sentiment Analysis, then the current Price $1.37 +3.18%, followed by 7D Sentiment shown as green stars (★★★½☆) with the numeric value +0.28 (Bullish), and finally (382 articles) indicating how many news articles were analyzed. The green color of the stars confirms the sentiment is in positive territory.
The Formula
The conversion from sentiment score to stars uses a linear mapping:
stars = ((sentiment + 1) / 2) × 4 + 1This maps the full -1.0 to +1.0 range onto a 1 to 5 star scale:
- -1.0 → ★☆☆☆☆ (1 star) — Extremely Bearish
- -0.5 → ★★☆☆☆ (2 stars) — Bearish
- 0.0 → ★★★☆☆ (3 stars) — Neutral
- +0.5 → ★★★★☆ (4 stars) — Bullish
- +1.0 → ★★★★★ (5 stars) — Extremely Bullish
Half-Star Precision
The star display supports half-star increments using gradient fills. For example, a sentiment score of +0.25 maps to 3.5 stars — shown as three full stars and one half-filled star. This gives you more granularity than whole stars alone.
Color Coding
Stars are color-coded based on the sentiment zone:
- Green (#22c55e) — Sentiment above +0.2 (bullish territory)
- Red (#ef4444) — Sentiment below -0.2 (bearish territory)
- Yellow (#eab308) — Sentiment between -0.2 and +0.2 (neutral zone)
The color provides an additional layer of information beyond the star count. You can spot a "red 2-star" rating instantly — it means bearish sentiment — without needing to read the numeric value.
Where Stars Appear
Asset Header
On every asset page, the header displays the 7-day sentiment as a star rating alongside the numeric score. This is usually the first thing you see when visiting an asset page and gives you an immediate sentiment summary.
News Cards
Individual news articles in the feed show a star rating based on the article's LLM sentiment score. This helps you quickly scan a list of articles and identify the most bullish or bearish ones without reading every headline.

Stars are a convenience layer — the numeric score underneath is always the more precise value. But for scanning dashboards, comparing assets, and getting a quick read, the star system makes sentiment data instantly accessible.
