Operational steps for data teams to capture slides, quotes, and sentiment at conferences and turn them into citable datasets.

Hook: Why conference data capture must stop being ad-hoc

Data teams are under pressure: leadership wants distilled intelligence from industry conferences (Skift Megatrends, CES, RSA) within 48 hours — not raw notes. Yet many capture programs still rely on scraps: blurry slide photos, scattered quotes in Slack, and one analyst’s rough sentiment read. The result is low trust, wasted time, and missed strategy windows.

Executive summary — what this guide delivers

Conference Data Capture: How to Turn Megatrends Panels into Structured Datasets is an operational playbook for data teams attending executive conferences in 2026. You’ll get a concise, repeatable workflow to capture slide metrics, timestamped quotes, and panel sentiment; transform them into citable CSV/Sheet/Airtable datasets; and deliver an executive summary and analysis ready for leadership.

Core outputs you should be able to deliver within 48–72 hours after a one-day conference:

Master dataset (CSV) with session, speaker, slide, quote, and sentiment metadata
Slide metrics table (chart counts, numeric callouts, visual density)
Quoted repository with verbatim text, timestamps and speaker attribution
Panel sentiment scores at sentence, speaker, and session levels
One-page executive summary and a 6-slide leadership deck

Why this matters in 2026

Events like Skift Travel Megatrends are now where strategy shifts are seeded. In 2026, three trends change the capture playbook:

Multimodal AI: Robust audio-to-text and image OCR let small teams produce structured outputs fast.
Real-time expectations: Leadership expects early signals for budgeting windows; delays erode value.
Privacy & IP awareness: Conferences and speakers are increasingly explicit about capture policy — compliance is non-negotiable.

Top-level workflow (the inverted pyramid)

Prepare: schema, roles, tooling and legal checks.
Capture: high-quality slide images, audio, live notes, and metadata.
Enrich: OCR, ASR, speaker diarization, and structural extraction.
Transform: normalize fields, deduplicate, sentiment-score, and label visual features.
Deliver: datasets + executive summary + reproducible scripts/templates.

Preparation: schema-first, not tool-first

Start with what leadership wants. Build a simple schema before you buy hardware or SaaS licenses. A schema prevents post-conference chaos and guarantees the datasets are analyzable.

Minimum viable schema (master dataset fields):

event_id — e.g., skift-megatrends-2026-nyc
session_id — session slug or numeric id
session_title
session_start / session_end (ISO 8601 timestamps)
speaker_id, speaker_name, speaker_org
slide_id, slide_image_url, slide_index
slide_text_extract (raw OCR)
slide_visual_features (chart_count, image_count, table_count)
quote_id, quote_text, quote_start, quote_end
sentiment_score (numeric), sentiment_label
confidence (source-specific score for OCR/ASR)
evidence_link (screenshot/audio clip)

Define this schema in a Google Sheet or Airtable before travel. Share it with stakeholders so everyone aligns on output expectations.

Roles & responsibilities for a compact 2–4 person team

Lead Analyst: schema owner, QA, and final deliverable author.
Capture Operator: collects slide photos, records audio, timestamps live notes.
Enrichment Engineer: runs OCR/ASR and performs speaker diarization after each session.
Communications/QC (optional): checks compliance, speaker permissions, and prepares evidence links for delivery.

Capture: what to record and how

Capture quality directly determines dataset usefulness. Prioritize these artifacts for every session:

Clean slide images — full-slide photos or PDFs. Aim for 300–600 DPI equivalent; use a tripod or smartphone clamp to avoid skew. Name files using event_session_slideIndex.jpg.
High-quality audio — capture the room feed if available; otherwise use lapel mics or a dedicated recorder. Save as lossless or high-bitrate MP3/AAC.
Live timestamped notes — record speaker turn starts (00:03:45) and slide changes. A simple timestamp column in a Google Sheet works.
Context metadata — room, panel moderator, intended audience level.

Pro tip (2026): many venues now provide an organizer feed or RTMP stream. Capture the stream if allowed — it’s ideal for downstream ASR and synchronization.

Enrichment: converting raw capture to structured fields

After the session, move quickly to enrichment. The sooner you run OCR and ASR, the fresher it is for leadership.

1. OCR slides to extract text and layout

Run images through a modern OCR pipeline that preserves layout (text blocks, titles, numeric callouts):

Google Cloud Vision / AWS Textract for production-grade OCR and table detection.
Open-source alternatives (Tesseract+layoutparser) for local processing.

Extracted outputs to store per slide:

title_text, body_text, bullet_count, numeric_entities (regex for % / $ / dates)
chart_type tags (pie, bar, line) via simple image classification or heuristic rules
visual_density score (text area proportion vs blank space)

2. ASR and speaker diarization

Turn audio into time-aligned transcripts. For 2026, use a hybrid approach:

Run a fast ASR (Whisper, OpenAI, AssemblyAI) for baseline transcripts.
Apply speaker diarization (pyannote, NVIDIA NeMo) and align speaker labels to timestamps.
Post-process with a domain lexicon (travel, sustainability, monetization) to fix industry terms.

Save sentence-level transcripts with start/end times and speaker_id to feed quote extraction and sentiment analysis.

3. Quote extraction & attribution

Define rules for what becomes a captured quote. Suggested rules:

Any sentence with a numeric claim (e.g., “We saw 40% YoY growth”) — capture verbatim.
Any phrase that leadership flagged in pre-briefing topics (e.g., “dynamic pricing”, “decarbonization”).
Contrarian statements or provocative lines (use keyword filters: risk, failure, challenge).

For each quote, record: quote_text, speaker_id, timestamp_start, timestamp_end, linked_slide_id (if referenced), and an evidence_link (audio or screenshot). Preserve provenance and storage references so leadership can audit claims later (see long-term storage and workflows).

Sentiment and stance: practical scoring for panels

Sentiment in conference panels is nuanced — speakers rarely use overtly positive or negative language. Use a layered approach:

Lexicon-based baseline (VADER or a tuned travel lexicon) for speed.
Transformer re-ranker (RoBERTa or a fine-tuned instruction model) for sentences near the polarity threshold.
Contrast labels: assign stance (optimistic/neutral/cautious) rather than raw polarity when appropriate.

Score at three granularities:

Sentence-level sentiment_score (float) and sentiment_label.
Speaker-level aggregation (mean sentiment, standard deviation).
Session-level trend (trend slope over session time to detect shifts).

Important: capture model confidence and flag low-confidence items for human review. For leadership, provide both the numeric score and two representative verbatim quotes that justify that score.

Transform: normalization, dedupe, and enrichment

Once OCR and ASR outputs exist, run a reproducible transform pipeline (Python or Google Apps Script) to:

Normalize timestamps and convert to UTC.
Deduplicate quotes and slide text fragments (fuzzy match 90%+).
Link quotes to slides via keyword overlap and timestamp proximity.
Tag domain concepts using a controlled vocabulary (pricing, distribution, sustainability, AI).

Store a provenance column for every record pointing to the raw file (slide image, audio clip, transcript) so leadership can audit claims. For long-term evidence preservation and shareable links, consider memory and archival workflows that preserve context and attribution.

Deliverables: what leadership expects

Leadership doesn’t want raw datasets; they want insight plus defensible evidence. Deliverables should include:

Master CSV with the schema described earlier.
Slide metrics table summarizing slide counts, average bullet density, percent of slides with charts, and numeric claims per session.
Quote repository with verbatim text, speaker, timestamps, and evidence links.
Sentiment dashboard (Google Data Studio / Looker / Tableau) showing speaker sentiment and session trendlines.
1-page executive summary with three signal takeaways, two supporting charts, and methodology/limitations bullet points.

Executive summary template (6 sections)

Headline takeaway (one sentence)
Key metrics (slides processed, quotes captured, sessions analyzed)
Top 3 themes (with representative quotes)
Sentiment snapshot (session-level heatmap)
Implications for FY26 planning
Confidence and limitations

Spreadsheet templates & quick formulas

Keep canonical templates in Google Sheets for quick post-conference delivery. Key sheets to include:

Master — complete dataset, linked evidence URLs.
Slides — slide_id, slide_img_url, ocr_text, chart_count, numeric_count.
Quotes — quote_id, speaker, text, start_ts, end_ts, slide_id, sentiment_score.
Summary — auto-calculated dashboard with pivot tables.

Example Google Sheets formulas:

Count slides per session: =COUNTIF(Slides!A:A, session_id)
Average sentiment per speaker: =AVERAGEIF(Quotes!B:B, speaker_name, Quotes!F:F)
Percent slides with charts: =COUNTIF(Slides!D:D, ">0")/COUNTA(Slides!A:A)

Automation & reproducibility

Automate as much of the enrichment pipeline as possible. Example stack used by many teams in 2026:

Storage: S3 or Google Cloud Storage for raw artifacts.
Processing: serverless pipelines (Cloud Run/Lambda) to run OCR/ASR and push results to BigQuery or Snowflake.
NLP: Hugging Face models for named-entity recognition and sentiment fine-tuning.
Visualization: Looker Studio or Athena-backed dashboards for quick delivery.

Keep all scripts in a Git repo and tag releases by event date for reproducibility (e.g., megatrends-2026-01-22-v1).

Ethics, compliance, and provenance

Not all events permit recording or redistribution. Before you capture:

Check the event’s media policy and obtain explicit permissions for recording.
When publishing quotes internally, include evidence links and timestamps to guard against misattribution.
Obey privacy laws for attendee or panelist data (GDPR-style rules). Minimize PII in delivered datasets.

“Leaders want a shared baseline before budgets harden.” — organizing premise behind Skift Megatrends, 2026

Case study: Skift Megatrends NYC (compact, 1-day capture)

Scenario: A 3-person data team covers five panels. They used the schema above and produced deliverables within 48 hours.

What they captured and how:

Slides: 65 slides photographed and OCR’d; slide metrics showed 72% contained numeric claims.
Quotes: 48 notable quotes captured; 12 numeric claims (e.g., “we saw 25% higher ancillary revenue in Q3”).
Sentiment: Session-level stance shifted from cautious to optimistic as panels discussed demand recovery; aggregated sentiment increased from 0.1 to 0.4 (scale -1 to 1).

Deliverables: a 1-page executive brief, a CSV master dataset, and an interactive dashboard. Leadership used the brief to reallocate marketing budgets within a week.

Common pitfalls and how to avoid them

Pitfall: No schema before capture. Fix: Define fields, evidence links, and formats pre-event.
Pitfall: Over-reliance on raw ASR without diarization. Fix: Prioritize speaker attribution pipelines for accurate quote capture.
Pitfall: Delivering data without provenance. Fix: Always attach the evidence_link column for claims.
Pitfall: Ignoring event recording rules. Fix: Clear capture permissions and make policy part of the pre-event checklist.

Methodology notes and limitations

Be transparent about what the dataset represents:

Sampling bias: Panels reflect invited speakers and organizers’ framing; do not infer population-level claims.
ASR/OCR error: Non-native accents, technical jargon, and noisy rooms will reduce confidence — show confidence scores.
Sentiment nuance: Categorical labels (optimistic/cautious) are interpretive — provide verbatim quotes for context.

Actionable checklist to use at the next conference

Pre-event: finalize schema, confirm recording permissions, and assign roles.
Day-of: capture slides, record audio, and timestamp slide changes.
0–12 hours after sessions: run OCR/ASR and diarization; extract quotes and initial sentiment.
12–36 hours: run normalization, dedupe, and produce the master CSV.
36–72 hours: finalize executive summary, dashboard, and deliver to leadership with evidence links.

Final takeaways

Schema-first capture turns messy conference output into citable intelligence.
Evidence-linking (screenshots/audio clips) is essential to maintain trust with leadership.
Layered NLP (lexicon + transformer) balances speed and accuracy for sentiment and quote extraction.
Automate reproducibly and treat each conference like a repeatable data product.
