Known limitations
These limitations describe confirmed NL Analytics behavior and current documentation scope.
Product scope
Current public docs cover English earnings-call transcripts. NL Analytics is not documented here as a generic upload-any-text product.
Future data-source expansions are not documented as current product scope.
There is no public end-user API documented for NL Analytics. These docs do not include API authentication, endpoints, schemas, SDKs, examples, rate limits, or automation workflows.
Coverage
The corpus source universe is LSEG earnings-call transcripts available to NL Analytics. Coverage varies by country, sector, firm, and time.
Refresh cadence is not documented as a guarantee.
Search and filtering
Query design affects every metric. Users may need to refine keywords, include plurals manually, validate suggested terms, and balance precision against recall.
The Risk Tool search form currently does not allow users to specify particular industries or firms before running a search. Users can focus on firms or industries after search through output files and supported Snippet Tool filters.
The nr_of_sentences variable currently does not adjust when users restrict a search by section or speaker, or when adjacent sentences are included.
Risk Tool search results are retained for 90 days. Search inputs remain available, but older searches must be rerun before their matched sentences can be inspected again in the Snippet Tool.
Metrics
Metrics are raw integer sentence-count measures. They are not black-box LLM scores, causal estimates, investment advice, forecasts, compliance determinations, or complete summaries of business risk.
Researchers still own construct validation, sample design, normalization choices, crosswalk checks, and empirical interpretation.
Topic Future is mentioned in NL Analytics materials as a metric under development. It is not documented here as an available product metric because current docs do not confirm that it appears in the user interface or export files.
Exports
Search result CSV files include all earnings calls in the selected date range, including rows where no sentences satisfy the query.
Authoritative CSV filenames, full schemas, and public sentence-download fields are not confirmed in these docs.
The GVKey crosswalk is a convenience output for downstream joins. Verify match quality before relying on joined results.
Compliance claims
These docs do not include compliance, certification, or regulatory-assurance claims.
