GapWatch Glossary
Authoritative definitions of GapWatch proprietary metrics and core concepts. These are the canonical references for GapScore, Velocity Score, and narrative intelligence terminology as used on this platform.
GapScore
Proprietary metric · 0–100 scaleA 0–100 metric showing how far a story's social media attention is out of sync with mainstream news coverage.
How it works
GapWatch tracks how often and how intensely a story is discussed on platforms like Reddit and X, then compares that to how often and how prominently it appears across more than 180 mainstream outlets. When social conversation significantly outpaces news coverage, the story's GapScore rises. When coverage keeps pace with public attention, the score stays low.
Reading the scale
| Range | Classification | Meaning |
|---|---|---|
| 0–39 | Aligned | Social and mainstream attention are broadly in sync. |
| 40–69 | Moderate Gap | Social is ahead of news, or coverage is narrow relative to interest. |
| 70–89 | High Gap | Noticeable underreporting relative to public attention. |
| 90–100 | Blind Spot | Large, sustained social conversation with minimal mainstream coverage. |
Why it matters
GapScore turns a qualitative hunch — “this feels undercovered” — into a comparable number you can track across stories, outlets, and topics. It helps journalists, researchers, and analysts quickly spot narratives that are big online but small in print, without reading every post and article themselves.

Velocity Score
Proprietary metric · 0–100 scaleA metric capturing how fast attention to a story is changing across social platforms and mainstream outlets.
How it works
GapWatch measures changes in mentions, engagement, and outlet pickup over short rolling windows, then normalizes those changes onto a 0–100 scale. Stories with rising mention and engagement curves get higher Velocity Scores. Stories that have plateaued or are fading get lower scores.
What it tells you
Velocity Score answers “Is this story taking off right now?” while GapScore answers “Is this story undercovered?” Used together, they distinguish slow-burn narratives from sudden spikes that may need immediate editorial or analytical attention.

Media Blind Spot
Classification · GapScore 90+A story with very high social attention and very low mainstream coverage — defined in GapWatch by a GapScore of 90 or above.
How GapWatch defines it
Many tools discuss blind spots in terms of political bias — stories one side of the spectrum covers and the other ignores. GapWatch instead measures a cross-channel gap: stories that audiences are already debating online that have not yet been picked up, contextualized, or fully reported by major outlets. GapWatch does not take positions on why gaps exist — only that they do.
Why it matters
Media blind spots are often where new narratives, controversies, and breaking developments first appear. By making them visible and measurable, GapWatch helps journalists, researchers, and analysts identify these stories before they break into the mainstream.

Narrative Propagation
Concept · measured by GapWatchThe process by which a story moves from its origin through social amplification to mainstream coverage — tracked by GapWatch across platforms and over time.
What GapWatch tracks
For each story, GapWatch follows where it starts (which platforms, communities, or outlets), how it spreads (growth in mentions, engagement, and outlet diversity), and how its GapScore and Velocity Score change as the narrative evolves.
Narrative maps and story graphs
GapWatch visualizes propagation with narrative maps and story graphs that show how a story branches into related threads and which actors drive each wave of attention. These views make it easier to see who moved first, who amplified, and when mainstream coverage began to catch up with — or diverge from — social conversation.

Coverage Gap
Concept · quantified by GapScoreThe measurable difference between the level of social media discussion about a story and the volume of mainstream news coverage it receives.
How it is measured
GapWatch quantifies coverage gaps using the GapScore metric — a 0–100 index derived from the ratio of social mention volume and velocity to mainstream article volume and prominence. The larger the gap between social attention and mainstream coverage, the higher the GapScore.
