What data for this category looks like
Financial report data for medical device enterprises comes primarily from publicly disclosed annual, semi-annual, and quarterly reports, as well as official announcements from corresponding exchanges. The data update rhythm follows fixed report cycles. A single financial report document usually includes sections such as main financial statements, R&D pipeline details, production and sales data, and medical device registration certificate information.
Document formats are mainly PDF and DOCX, with multiple types of embedded tables. These include numerical tables for financial revenue, and nested detail tables for R&D products. Fields include the number of devices, number of consumables, revenue amount, and more. Corresponding units are units, pieces, ten thousand yuan, and others. Some financial reports from overseas-listed companies also include foreign currency-denominated fields.
Constraints for document parsing and chunking
The multi-type nested tables, multi-unit fields, and fixed-cycle update features of medical device financial reports create clear constraints for the parsing and chunking process. Nested detail tables require parsing tools to fully identify hierarchical structures, and avoid missing key fields such as registration certificate numbers and validity periods in sub-tables. The associated nature of multi-unit fields requires chunking to retain the binding relationship between fields and their corresponding units, and not split them to lose context association. Single documents have large volume and include cross-chapter data, so chunking must split according to chapter logic, while retaining overlapping content in adjacent chunks to maintain data coherence. Financial reports for overseas-listed companies include multi-language or multi-currency fields, so parsing must support non-Chinese field annotations.
How to configure the settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Single medical device financial report PDF or DOCX files usually have large volume and contain multiple nested tables. The default timeout period is insufficient to complete full parsing |
maxChunkSize | 1200–1500 characters | Long paragraphs of R&D pipeline descriptions and detail tables exist in financial reports. This length can fully retain all associated data of a single product group |
chunkOverlap | 200–300 characters | Financial report data has chapter associations across chunks. Overlapping content prevents key context from being split and broken |
ENABLE_NESTED_TABLE_PARSE | Enabled | Medical device financial reports include nested tables such as R&D pipelines and production details. Enabling this setting allows full extraction of sub-table fields |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Some annual financial reports include multi-page attachment PDFs. This setting supports upload and parsing of large-volume files |
RECALL_CHUNK_COUNT | Top 8 entries | Financial report retrieval needs to cover multiple sets of associated data. This recall count ensures that returned results contain sufficient valid information |
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. It is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- Phenomenon: Retrieved data is less than the content in the original Excel or PDF table. For example, when querying the revenue of an overseas subsidiary, only the main table data is returned and the detail items in the sub-table are missing. Cause: The
ENABLE_NESTED_TABLE_PARSEconfiguration is not enabled, resulting in missing sub-table fields nested in the main table. - Phenomenon: After uploading a PDF-format financial report, the parsing status shows a timeout error, and the status code returns
504. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted. The default timeout period is insufficient to complete parsing of large-volume documents. - Phenomenon: Chunked content loses the association between chapter titles and corresponding data. For example, revenue data from the "cardiovascular devices" chapter is assigned to an unrelated chunk. Cause: The parameter that retains chapter titles during chunking is not configured, resulting in separation of product chapters and corresponding revenue data in the financial report.
How to confirm the configuration is correct
- Upload a single medical device quarterly financial report, check the parsed chunk list, and confirm that each chunk contains complete table rows, corresponding unit labels, and the affiliated chapter title.
- Initiate a retrieval test, enter a query term related to the financial report content, and confirm that the returned results include all relevant fields and values from the original document.
- Check the parsing log, confirm that the
ENABLE_NESTED_TABLE_PARSEparameter is enabled, and there are no error records of failed nested table parsing. - Test uploading a large-volume annual financial report PDF, confirm that the upload and parsing process proceeds normally, with no timeout or file interception prompts.
