What this type of data looks like
Biologics research report data primarily comes from securities firm pharmaceutical industry research reports, National Medical Products Administration CDE public review files, pharmaceutical company official clinical and financial report announcements, and monthly monitoring reports from pharmaceutical industry associations. There are two update cycles: regular securities firm reports are updated quarterly and monthly. Emergency review and batch issuance data are synced in real time. Document structures typically include core product parameters, such as monoclonal antibody specifications and vaccine dosage units, competitive product benchmarking data, and policy interpretation excerpts. Fields include product generic names, review numbers, batch issuance lot numbers, units such as IU/bottle and mg/vial. Some long documents include clinical data tables.
What constraints these characteristics impose on citation source and traceability
The precise parameter attributes of biologics research reports require traceability to match original text fragments corresponding to specific parameters. Generic keywords must not be used to avoid confusing similar data from different products. Real-time updated batch issuance and review data require traceability links to point to the latest version of official documents. Knowledge base historical snapshots must not be used. In scenarios with cross-referencing across multiple sources, the original data source hierarchy must be clearly marked. This distinguishes between securities firm interpretations and official raw data. For clinical table fragments in long documents, the specific page number or table number must be located. Only using paragraph ranges as positioning criteria must be avoided to prevent parameter matching errors.
How to configure the settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_max_length | 800-1200 characters | Biologics research reports often contain precise parameters with units. Too long a chunk will break the contextual association of parameters. Too short a chunk will fail to cover complete parameter explanations |
recall_top_k | Top 3-5 results | Biologics parameters are precise. Too many recalled results will introduce irrelevant data and reduce traceability efficiency |
similarity_threshold | 0.75-0.85 | Filter low-similarity irrelevant recall results to avoid incorrectly associating non-target product parameters with traceability content |
parse_enable_table | Enable table parsing and retain cell metadata | Clinical data tables in biologics research reports contain core parameters. Table position and field correspondence must be fully retained to facilitate accurate positioning of traceability fragments |
chunk_overlap | 100-150 characters | Biologics parameters often span multiple chunks. Overlapping chunks ensure complete parameter context and avoid loss of key associated information during traceability |
source_link_type | Point to the online address of the original document | Biologics research reports include real-time updated batch issuance and review data. The latest version of official documents must be linked. Knowledge base historical snapshots must not be used |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- Phenomenon: The interface returns a string of red numeric error codes, and citation cannot be completed. Cause: The
source_link_typeparameter is not configured correctly, or uploaded documents in the knowledge base are not associated with their original online addresses. This results in failed traceability link generation and triggers parameter errors. - Phenomenon: The cited fragment cannot open the online preview of the original document before the chunk was created. Cause: The
sourceLinkEnableparameter is not enabled, or the configured traceability link only points to the local storage path of the knowledge base. It is not associated with the public online address of the original document. - Phenomenon: The output content does not mark source information, making it impossible to confirm whether it comes from the knowledge base. Cause: The
show_source_detailparameter is not enabled, or original document metadata fields are not retained during document chunking. This results in failure to extract source identifiers.
How to confirm the configuration is complete
- Upload a biologics research report document. After triggering knowledge base parsing, view the parsed chunk content to confirm that the table structure and parameter fields are fully retained.
- Initiate a search related to biologics. Check the traceability area of the returned results to confirm that the online link of the original document and the specific fragment position are displayed.
- Adjust the recall-related parameters, then initiate the same search. Observe the change in the number of recalled results to confirm that the parameter configuration takes effect.
- Check the associated information of knowledge base documents to confirm that the public online address of the original document has been bound. Local storage paths alone should not be used.
