Workflow · Topic chronology

Build a Telegram topic timeline from cited posts

Build a chronological, evidence-linked account of how a topic appeared and changed across selected Telegram sources and a defined period.

Direct answer. The Ocean can retrieve exact and semantically related posts about a defined topic inside selected indexed sources, apply a date window, and organize cited evidence into a chronology. The timeline can highlight first observed appearances, later updates, disagreements, and changes in framing, but it remains a synthesis of retrieved evidence rather than a complete propagation graph or proof of causal influence.

Research fit

Who this workflow is for

Researchers reconstructing an event or narrative across public channels who need readable chronology, source-level citations, and explicit gaps instead of a relevance-ranked list with dates mixed together.

01

Define the topic

Specify entities, claims, event boundaries, and exclusions so the timeline is about one research proposition rather than every use of a broad term.

02

Select sources and dates

Choose the relevant channel set and an explicit period; record sources with no messages inside it.

03

Retrieve exact and semantic evidence

Use literal matches for known wording and semantic search for paraphrases, translations, or conceptually related updates.

04

Order and synthesize

Arrange verified posts chronologically, preserve disagreements, and label source claims separately from independently confirmed facts.

05

Audit gaps

State missing history, unavailable sources, retrieval limits, and whether the earliest row is merely earliest in the selected corpus.

Practical module

Cited topic-timeline template

A strong timeline uses evidence rows first and narrative synthesis second, so a reviewer can challenge every turning point.

Topic definitionEntities, distinctive claims, languages, aliases, exclusions, and the decision the chronology should inform.
PeriodInclusive start, exclusive end, timezone, and explanation for why those boundaries matter.
Evidence rowTimestamp, source, concise observation, exact quotation status, and direct Telegram permalink.
Change typeFirst observed mention, update, repetition, contradiction, correction, escalation, or framing shift.
Verification stateSource claim, corroborated observation, disputed statement, or unresolved gap.
Coverage noteSelected sources with messages, zero-message sources, and important unindexed evidence.

Analysis contract

What the calculation actually does

The workflow combines hybrid semantic retrieval with deterministic exact matches and stored publication timestamps, then asks the model to synthesize only the cited context in chronological order.

Scope

Selected indexed Telegram sources and an explicit or interpreted publication period. Full-period summaries fail closed when the message count exceeds the configured safe limit.

Measured fields

  • Publication timestamp
  • Source and message reference
  • Exact or semantic relevance
  • Chronology position
  • Evidence citation
  • Coverage status

Coverage rules

  • Source scope and period are stated in the answer
  • Exact matches remain distinguishable from semantic retrieval
  • Zero-message selected sources are recorded for period work
  • Oversized periods require narrowing
  • First appearance remains corpus-bounded

Questions to ask

  • Build a timeline of how these channels discussed the policy change in August.
  • Show the first mention, later updates, and disagreements about this launch.
  • Create a cited chronology of the narrative and identify important evidence gaps.

Telegram topic-timeline recipe

A structured method for turning retrieved posts into a source-checkable chronology with explicit event types and coverage gaps.

Copy-ready query

Across [selected channels] from [start] to [end], build a chronological timeline for [defined topic]. Include exact and semantic evidence, source, timestamp, permalink, change type, and verification status. Preserve disagreements, name zero-message sources, and describe the earliest item only as earliest found in this corpus.

Deterministic calculation

plain semantic

Hybrid retrieval plus chronological ordering of cited stored publication timestamps; synthesis is narrative and never replaces the underlying evidence rows.

Inputs to set

Topic
Entities, claims, aliases, languages, and exclusions that bound the investigation.
Sources
The selected ready channels whose indexed history is in scope.
Period
Explicit start and end dates with timezone.
Timeline taxonomy
First mention, update, repetition, contradiction, correction, or shift.

Expected output

  • Chronological evidence rows
  • Cited turning points
  • Source disagreements
  • Verification status
  • Coverage and earliest-evidence caveat

Coverage rules

  • Do not infer propagation from timestamp order
  • Do not omit zero-message selected sources
  • Do not summarize an oversized period
  • Keep every substantive event linked to evidence
  • Review translations and paraphrases in the original post

# Telegram topic-timeline recipe

A structured method for turning retrieved posts into a source-checkable chronology with explicit event types and coverage gaps.

## Calculation

- Mode: plain_semantic
- Formula: Hybrid retrieval plus chronological ordering of cited stored publication timestamps; synthesis is narrative and never replaces the underlying evidence rows.

## Query

Across [selected channels] from [start] to [end], build a chronological timeline for [defined topic]. Include exact and semantic evidence, source, timestamp, permalink, change type, and verification status. Preserve disagreements, name zero-message sources, and describe the earliest item only as earliest found in this corpus.

## Inputs

- **Topic:** Entities, claims, aliases, languages, and exclusions that bound the investigation.
- **Sources:** The selected ready channels whose indexed history is in scope.
- **Period:** Explicit start and end dates with timezone.
- **Timeline taxonomy:** First mention, update, repetition, contradiction, correction, or shift.

## Expected output

- Chronological evidence rows
- Cited turning points
- Source disagreements
- Verification status
- Coverage and earliest-evidence caveat

## Coverage checks

- [ ] Do not infer propagation from timestamp order
- [ ] Do not omit zero-message selected sources
- [ ] Do not summarize an oversized period
- [ ] Keep every substantive event linked to evidence
- [ ] Review translations and paraphrases in the original post

Boundaries

What this does not establish

  • Retrieved evidence may omit relevant paraphrases
  • A chronology does not prove causation between sources
  • The first row may not be the original publication
  • LLM synthesis requires source-level human review
  • Large periods may need narrower sources or dates for safe processing
