What data for this category looks like
Packaging and printing financing daily report data comes from three main sources: public disclosures of national printing industry associations, public information released by local light industry manufacturing competent departments, and financing announcements actively issued by packaging and printing enterprises. The platform updates one single financing event document daily. Each document contains these fields: full enterprise name, financing date, financing amount (unit: ten thousand RMB), investor entity, financing round, core business direction, and overview of implemented projects. Most documents use structured tables paired with short explanatory text. Some documents attach enterprise qualification certificate attachments.
Constraints on knowledge base retrieval and recall from these characteristics
Non-standard data from multiple sources creates large differences in single document structure. This increases format adaptation difficulty during chunking. The daily update rhythm requires the knowledge base to support incremental import. This avoids resource consumption caused by full synchronization. The financing amount field uses ten thousand RMB as its unit. Retrieval requires unified numerical mapping rules. This prevents accuracy degradation from unit confusion. Special business fields for the packaging and printing industry require category keyword filtering in the recall link. This excludes irrelevant industry financing events and narrows the retrieval scope.
Configuration Settings
| Configuration Key | Recommended Value | Rationale |
|---|---|---|
chunk_length | 800–1200 characters | Single financing event text for packaging and printing financing daily reports is compact. Excessively long chunks will split associated fields such as financing amount and financing round. Excessively short chunks will cause context breaks in chunks. |
recall_count | Top 6–10 entries | The number of financing events in the packaging and printing industry per day is limited. This range covers valid daily retrieval results and avoids interference from redundant information. |
similarity_threshold | 0.78–0.85 | Accurate distinction between financing events of different enterprises and different rounds in the same industry is required. A threshold that is too low will mix in irrelevant industry content, while a threshold that is too high will miss accurately matched items. |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Single financing daily report document has a small volume. 300 seconds is sufficient to complete format parsing, chunking, and metadata extraction. |
INCREMENTAL_UPLOAD_ENABLE | Enabled | Financing daily reports update one single event per day. Incremental import avoids repeated uploads of full historical data and improves update efficiency. |
rerank_return_count | Top 3–5 entries | Most retrieval demands focus on accurately obtaining single or a small number of core financing information. Reducing the returned range after reranking improves reading efficiency. |
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 specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Phenomenon: The exported knowledge base file size is only hundreds of KB, and some financing document content is missing. Cause: The full synchronization switch is not enabled, and only temporary chunk data from the current session is exported.
- Phenomenon: Image links not from online image beds in markdown files imported into the knowledge base cannot be displayed normally. Empty placeholder fields are returned during retrieval. Cause: Local image paths are not replaced with the platform's built-in image bed address. Only original local file paths are retained.
- Phenomenon: A large number of financing events from non-packaging and printing industries are mixed in retrieval results. The number of recalled entries exceeds the expected range. Cause: No category keyword filtering rules are set. Matching conditions for packaging and printing related fields are not added during the retrieval link.
How to Confirm Configuration Is Correct
- Upload a test packaging and printing financing daily report markdown file. Check the number of parsed chunks and field integrity to confirm that the chunk length configuration takes effect.
- Initiate a retrieval containing industry keywords. Verify the industry relevance of returned results. Adjust the similarity threshold and recall count to meet requirements.
- Perform an incremental import operation. Check the knowledge base update log to confirm that only the day's financing events are added, and historical data is not uploaded repeatedly.
- Export all knowledge base content. Verify the number and type of documents included in the file to confirm that the export configuration covers all valid chunks and attachments.
