What the data for this category looks like
Hotel and catering industry research report data primarily comes from public industry research institution reports, quarterly financial reports of chain brands, monthly statistics from local catering and accommodation industry associations, and public operational disclosures of leading brands. Update cycles vary widely. Financial reports are updated quarterly. Industry association statistics are released monthly. Special research reports have no fixed update schedule. Most document structures include fields such as regional market size, per-store revenue, customer unit price, table turnover rate, and occupancy rate. Units include RMB yuan, person-times, room-nights, and percentage, among others.
What constraints these characteristics impose on the citation source and traceability link
Dispersed data sources and inconsistent update cycles require the traceability process to accurately match the identification systems of different data sources. This avoids confusing similar data released by different institutions. The quarterly update rhythm of financial report data requires traceability records to mark the report release time and financial report period. This prevents citing expired historical data. The presence of multi-dimensional segmented fields requires traceability information to accurately point to specific chapters or footnote paragraphs in the document, rather than just the file name. This ensures the specific cited content can be verified.
How to configure the settings
| Configuration Item | Recommended Value | Basis for This Value |
|---|---|---|
Recall Count | Top 10–15 entries | Hotel and catering research reports cover multiple segmented dimensions, requiring sufficient recall volume to cover multiple types of data such as regional and single-store data |
Similarity Threshold | 0.75–0.85 | Segmented fields such as customer unit price and table turnover rate have small semantic differences, requiring a high threshold to filter irrelevant recall results |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | A single research report may contain multi-page segmented data, requiring sufficient parsing time to complete complete text extraction |
Segment Length | 800–1200 characters | Data analysis paragraphs in research reports are long. Excessively long segments will destroy data context association, while excessively short segments will lose field association |
Citation Source Display Fields | Report title, publishing institution, release time, document page number | Match the multi-dimensional identification requirements of hotel and catering research report traceability, ensuring that cited content can be accurately verified |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three common mistakes
- The citation source field of returned results is empty. The cause is that the required items of
Citation Source Display Fieldsare not configured, and only the basic recall function is enabled without enabling the traceability display configuration. - Recall results include expired quarterly financial report data. The cause is that the
Document Update Time Filterparameter is not set, and no limit is applied to only recall research reports and financial report documents from the past 12 months. - Calls cannot correctly reference segmented field variables in the knowledge base. The cause is that fields such as customer unit price and table turnover rate in the research report are not configured as extractable knowledge base variables, and only the original document is imported without enabling the field extraction function.
How to confirm the configuration is complete
- Upload a hotel and catering research report document, start retrieval and check the citation source area of the returned results, confirm that the preset report title, publishing institution and other fields are displayed.
- Enter a query containing regional customer unit price, check whether the similarity score of the recall results falls within the preset interval.
- Upload a quarterly financial report document, confirm after retrieval that the citation source marks the financial report release period and time, and no expired data appears.
- Check the knowledge base disk usage statistics page, confirm that the statistics include three types of data: original files, split file blocks, and embedding vectors.
