Comparative VADER Sentiment Dashboard

Interactive review of baseline and improved methods across minScore=0.5 and maxScore=0.5 endpoint datasets. The live multi-subreddit block below fetches fresh ReleaseTrain slices on each page load and runs VADER in the browser.

Live multi-subreddit VADER

Loading ReleaseTrain data and VADER…

Comment-index trajectories: up to 5 top posts for the selected subreddit (comment count, then score).

Sources: three merged filter slices (up to 500 posts each): Pool (minComments≥1, no post-score filter), Class 1 (minScore=0.5 on post), Class 2 (maxScore=0.5). Each post is tagged with the slice(s) it appeared in. Top 5 per target subreddit by comment count then score, preferring at least one Class 1 and one Class 2 when available. One line chart per post (VADER compound vs chronological comment index). Click a point on any chart or the header link to open that Reddit thread.

All meta subreddits — balanced min / max post scores

Loading subreddit list and class slices…

Up to 6 charts: up to 3 from Class 1 (min post score ≥0.5) and 3 from Class 2 (max ≤0.5) per sub. If a cohort is missing, you get up to 5 from the available slice only, or a mixed 5 (e.g. 1+4). The dropdown is the full releasetrain.io/api/reddit/meta/subreddits list (case-insensitive, deduplicated, sorted). Many names may have no rows in the current min/max samples—use another or Refresh.

Slices: minComments=3&minScore=0.5 vs minComments=3&maxScore=0.5 (500 rows each), filtered to the selected subreddit. Interactive Plotly: click a point to open the Reddit thread.
