What Data for This Category Looks Like
Photovoltaic enterprise financial report data mainly comes from annual reports, quarterly reports and temporary announcements publicly disclosed by domestic and overseas stock exchanges, supplemented by industry chain supply and demand reports released by industry associations. Data updates are concentrated in the statutory disclosure windows at the end of quarters and the end of the year, and temporary announcements are released in real time with major changes in business. The structure of a single financial report document includes sections such as core financial indicators, production capacity and shipment data, and industry chain layout analysis. Fields include component shipments, unit production costs, installed capacity, industry chain revenue scale, etc. Units mostly use industry-standard metrics such as GW, yuan per watt, and ten thousand yuan. Some documents embed charts and tabular data.
Constraints on Knowledge Base Retrieval and Recall
The multi-source release, specific industry field units, embedded charts, and concentrated disclosure characteristics of photovoltaic financial reports impose multiple constraints on the retrieval and recall process. First, documents from multiple channels including exchanges and industry associations require unified indexing rules to avoid matching deviations for the same indicator data from different sources. Second, industry-specific measurement units such as GW and yuan per watt must be included in the retrieval matching logic to prevent invalid recall results caused by unit confusion. Embedded charts and tabular data require retrieval tools to support parsing and recall of non-text content. Structured sections of long documents require reasonable segmentation strategies to avoid broken context that disrupts complete analysis logic. The concentrated disclosure window will trigger a large number of index update requests in a short period, requiring adaptation to high-concurrency retrieval pressure.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_IMAGE_ENABLE | Enabled | Photovoltaic financial reports embed charts of production capacity and shipment volume, requiring extraction of text data within charts |
CHUNK_SIZE | 800–1200 characters | A single section of a photovoltaic financial report contains complete quarterly production capacity data, avoiding splitting that breaks indicator relevance |
RECALL_TOP_N | Top 6–8 results | Photovoltaic financial reports have numerous and scattered indicators, requiring recall of sufficient relevant segments to cover complete analysis logic |
SIMILARITY_THRESHOLD | 0.72–0.85 | Low-correlation industry-general expressions must be filtered out, retaining results that accurately match photovoltaic financial report indicators |
UPLOAD_FILE_MAX_SIZE | 500 MB | Single annual financial report PDF/DOCX files typically do not exceed this threshold, avoiding upload timeouts |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Large financial report documents contain multiple charts and tables, requiring sufficient parsing time |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Issue: When uploading a DOCX document of a photovoltaic financial report that contains embedded images, the interface displays an error prompt "Incorrect file format". Cause: The
PARSE_IMAGE_ENABLEconfiguration item is not enabled, or the parsing service does not support specific encoding formats of DOCX embedded images. - Issue: When calling the interface to upload HTML-formatted financial report titles and content via an external program, a
400 Bad Requeststatus code is returned. Cause: Thetitleandcontentfields are not passed in the JSON structure required by the official interface, or a valid knowledge base ID parameter is not included. - Issue: After selecting the "Question and Answer Splitting" training mode, production capacity data embedded in charts of financial report documents cannot be recalled. Cause: The question and answer splitting mode disables non-text content parsing by default, and the
PARSE_IMAGE_ENABLEconfiguration item is not enabled to support image content extraction.
How to Verify Proper Configuration
- Upload a photovoltaic financial report DOCX document that contains embedded charts, view the parsed text content, and confirm whether relevant data within the charts has been extracted.
- Search for keywords related to photovoltaic industry-specific indicators, check the relevance of recall results, and adjust the similarity threshold to a range that meets business requirements.
- Call the official document upload interface, pass test titles and HTML content, and check whether corresponding entries are generated in the knowledge base.
- Select multiple uploaded financial report documents and attempt batch download, confirming that the batch download process can be triggered normally.
