AI-native match evidence · Retrieval

Asking the match, not scrubbing the timeline.

BlueX studies how complete-match observations can become searchable football context while every answer remains linked to source video.

A complete football sequence organized as searchable, time-linked match evidence

Research question

How can a tactical question return the right moment, its setup, and its evidence without manual video tagging?

Why this matters

Study the behavior that changes the work.

Search becomes useful only when the system understands a sequence as football context and can return the footage that supports its answer. A summary without the original timeline is not enough for match review.

01

Complete-match context

Organize observations, phases, actions, participants, and outcomes across the full timeline rather than a hand-picked clip set.

02

Semantic retrieval

Study how football questions map to the sequence and evidence a coach or analyst actually needs to review.

03

Evidence chain

Return time-linked video, supporting observations, confidence, and review state with the interpretation instead of only an answer.

Validation principles

Evidence before a claim.

Analysts can move from a football question to reviewable match evidence without rebuilding the same timeline through manual tagging and scrubbing.

V1

Test tactical questions across a complete match, including moments that are similar in appearance but different in football meaning.

V2

Review whether the returned interval includes the relevant setup, action, response, and outcome.

V3

Audit unsupported answers, missed evidence, taxonomy drift, and reviewer correction as first-class retrieval results.

Reading standard

Evidence stays attached.

01

Every answer remains linked to the source interval and evidence used to produce it.

02

The system distinguishes observed facts, contextual inference, and analyst interpretation.

03

Unsupported or ambiguous questions return an explicit review state rather than fabricated certainty.
