Reproducibility checklist

Use this checklist when an NL Analytics output will support a paper, policy note, appendix, replication file, monitoring output, report, or dashboard.

Search definition

Record:

• Exact query string.
• Date range.
• Selected metrics.
• Search options used where applicable.
• Any document-level or within-document filters used.
• Merge logic if searches were combined.

Review evidence

Keep notes from matched-sentence review:

• Examples of true positives.
• False positives and exclusions added.
• Missing terms added during refinement.
• Ambiguous terms and how they were handled.

Matched-sentence review supports auditability. It does not, by itself, prove construct validity.

Export context

Record:

• Export date.
• Corpus coverage statement used for the analysis.
• File downloaded.
• Search metadata or configuration file where available.
• Product share link where used.

Do not rely on a saved search or share link alone as a replication package. Keep exported files, query metadata, and downstream code or notes together.

Downstream analysis

Record:

• Join key.
• Identifier checks.
• Sample restrictions.
• Whether raw counts were normalized by nr_of_sentences.
• Any filtering of zero rows.
• Version of the downstream dataset.

Zero Exposure means the selected query did not match sentences in that transcript. It does not mean the company had no real-world exposure to the topic.
