Weighted Sentiment Metrics

Definition

The Sentiment Weighted is an improved version of the Sentiment Balance that also takes into account the Unique Social Volume.

Why Sentiment Balance needs improvement?

Sentiment Positive/Negative/Balance metrics' values are in the interval [-social_volume; +social_volume] where social_volume is the number of messages that mention a given coin.

This makes the values of different assets hard to compare, as the mentions of Bitcoin are magnitutes higher compared to the mentions of a small token.

Sentiment Weighted Intuitive Definition

Sentiment Weighted adjusts the values by considering the number of mentions, standardizing data to make diverse asset sentiments comparable.

This means that spikes/dips in the metric will be seen when there is:

• a lot of mentions for a coin
• most of the mentions are expressing the same sentiment -- most are positive or most are negative

If the sentiment is mixed, or the asset is not mentioned a lot, there will be no spikes/dips.

Sentiment Weighted Technical Definition

The metric is defined as a rolling Z-score of the term X, where:

More precisely we choose a duration $d$ which will be the length of our sliding window. Then for any timestamp $t$ we consider the population $X(t,d)$ consisting of all values of $X(t')$ for all timestamps $t'$ between $t-d$ and $t$. If we use $\mu$ and $\sigma$ to denote mean and standard deviation, then we define Sentiment Weighted as:

This score can be explained as a social-volume-weighted sentiment balance $-$ it spikes when the social volume is really high and the vast majority of the messages in it are very positive at the same time. Dips will occur when the social volume again is high, but the overall sentiment is negative. In case the volume is high but the sentiment is mixed, or the sentiment has a strong positive (negative) polarity but with a low volume, the Sentiment Weighted metric won't have significant changes and will stay around 0.

We have 5m, 1h, and 1d weighted sentiment metrics. The difference between them is in the metrics that we use to calculate them.

• for sentiment_weighted (5m) we use sentiment_balance (5m) and unique_social_volume (5m)
• for sentiment_weighted_1h we use sentiment_balance (1h) and unique_social_volume_1h
• for sentiment_weighted_1d we use sentiment_balance (1d) and unique_social_volume_1d

The difference between base metrics lies in the interval on which we aggregate these metrics. In case of 5m aggregated metrics when we calculate standard deviation and average for a window $d$ we take $d$ 5m's datapoints.

In case of 1h aggregated metrics -- we take $d$ 1h's datapoints.

In case of 1d aggregated metrics -- we take $d$ 1d's datapoints.
