What data for this category looks like
The data sources for film theater financing daily reports are mainly National Film Bureau filing announcements, publicly disclosed project financing notices from industry associations, and official announcements from production companies. Updates are released every working day. No new data is added on non-working days. Documents use a structured table format. Each record contains 7 fixed fields: project name, filing number, full production company name, financing amount (unit: ten thousand RMB), financing round, disclosure date, and original announcement link. There is no redundant nested content.
Constraints for citation sources and traceability
The unique identifier field is the filing number. The traceability link must use this field as the core basis for cross-data source matching. This avoids matching errors caused by project name abbreviations or changes to production company names. Updates follow a working day schedule. Filter invalid updates from non-working days during data source synchronization. This ensures all retrieved traceability data is the latest valid disclosure content. Single record structures are fixed with clear fields. No complex long text splitting is required. Ensure each field’s value exactly matches the original announcement. This prevents information deviations during traceability. The original announcement link is the final traceability basis. It must be bound one-to-one with the filing number. This allows each record to directly jump to the official disclosure page.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
source_id_field | Filing Number | Each record in film theater financing daily reports uses the filing number as its unique identifier, which can directly link to the original disclosure announcement to enable accurate traceability |
Recall count | Top 8 entries | The number of disclosed entries in a single financing daily report typically ranges from 5 to 10. Retrieving too many entries will introduce irrelevant data and reduce traceability accuracy |
Similarity threshold | 0.75-0.85 | Fields such as financing project names and filing numbers have strong recognizability. A threshold that is too low will match irrelevant financing projects, while a threshold that is too high will miss valid traceability results |
Rerank result count | Top 3 entries | Each financing record corresponds to a single disclosure announcement, so precise traceability can be completed without excessive results |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Financing daily report documents are usually structured tables, so parsing takes relatively little time. Setting a timeout avoids unnecessary waiting |
Chunk size | 1000-1500 characters | The text description of a single financing record is relatively short. An overly long segment will introduce irrelevant fields, while an overly short segment will damage record integrity |
The parameter values provided on this page are all common recommended starting points for determining 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
- Phenomenon: The
source linkfield in traceability results is empty. Cause: The URL of the disclosure announcement was not configured to the associated field corresponding tosource_id_field. Only the filing number was extracted, and no cross-table association was completed. - Phenomenon: Unformatted raw Markdown code appears in the context citation area. Cause: The
Chunk sizewas set too short. This splits a single financing record into multiple fragments, causing format markers to be truncated. - Phenomenon: The content of the corresponding film theater financing daily report cannot be retrieved after submitting a query. Cause: The
Similarity thresholdwas set too high, filtering out financing projects with similar names but different filing numbers. Orsource_id_fieldwas not configured for precise matching.
How to confirm configuration is correct
- Upload a single film theater financing daily report document. Check the parsed field list to confirm that the
备案编号andsource linkfields have been correctly extracted. - Initiate a test query containing a specific filing number. Verify whether the traceability link of the corresponding disclosure announcement is included in the retrieval results.
- Adjust the
Similarity thresholdto 0.7 and 0.85 respectively for testing. Confirm that the number and accuracy of retrieval results meet expectations. - Check system logs. Confirm that the time taken to parse the document does not exceed the value set for
PARSE_FILE_TIMEOUT_SECONDS, with no timeout errors.
