Corpus availability

Check whether the calls in NL Analytics cover the sample your research needs.

Current scope

The corpus consists of English earnings-call transcripts available in NL Analytics. You cannot upload your own documents or search other content types.

Check sample availability

1. Define your target firms, countries, sectors, and time period.
2. Run an exploratory search and export the call-level data.
3. Tabulate calls by headquarterscountry, economic_sector, and date_q. Compare them with your intended sample, including firms or periods with missing calls. Keep zero-match rows; those calls are present.

Then check whether topic matches vary enough within that sample. Broader query terms can find more language; they cannot add missing calls.

• Refine the query when relevant language is missed or matches are noisy. Use sentence review to choose changes.
• Narrow the research question when coverage or topic variation supports only part of your intended sample.
• Postpone the topic when too few calls or too little relevant language remain to support the design.

Refresh timing

The corpus refreshes roughly every two weeks, typically every 13 to 16 days. The timing is approximate. Record the corpus statement and export date used for your analysis.
