What the Data for This Category Looks Like
Data for kitchen and bathroom appliance financing daily reports is primarily sourced from public investment and financing platforms, official corporate financing announcements, and industry information disclosure platforms. It is updated daily. Most documents are in Excel format. Each daily report includes financing project entries for a single category or all categories of kitchen and bathroom appliances. Fields include financing party name, corresponding kitchen and bathroom appliance product lines, financing amount, financing round, investor, information release date, and other relevant details. Amount units are mostly ten thousand yuan or hundred million yuan. Some supporting announcements are in PDF format, containing financing agreement details and enterprise qualification descriptions.
Constraints Imposed by These Characteristics on Document Parsing and Chunking
Daily updated batch documents require the parsing process to support high-concurrency batch handling, to prevent parsing timeouts for individual documents. Excel format documents often have merged cells and cross-row fields, which can cause field misalignment after basic parsing. Kitchen and bathroom appliance product lines have rich, diverse categories. A single financing project may be linked to multiple product lines. Chunking must split content by financing project, not by individual field, to avoid breaking associated information. Supporting PDF announcements contain long paragraph text. Chunking must retain semantic completeness while adapting to the context length limits of subsequent large models. Some documents use mixed amount units. A unit verification step must be added after parsing to avoid numerical deviations in subsequent processing steps.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Adapts to the total size of a single batch daily report Excel file and supporting PDF files, to avoid large file upload interruptions |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Addresses single-file processing time during batch multi-document parsing, to avoid mid-process timeout interruptions |
chunk_size | 800–1200 characters | Adapts to the information density of kitchen and bathroom appliance financing projects, retains semantic completeness of associated fields for a single project, and complies with large model context window limits |
chunk_overlap | 100–150 characters | Avoids truncating financing clauses and product line associated information during chunking, ensures cross-chunk semantic coherence |
similarity_threshold | 0.75 | Filters duplicate parsed entries for the same financing project, adapts to duplicate reporting situations that may appear in daily reports |
recall_top_k | Top 5 entries | Matches the volume of financing information recalled for a single round of queries, avoids redundant information interfering with large model output |
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 specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: After uploading an Excel format financing daily report, the backend shows no errors but the parsing result is empty. Cause: The Excel file parsing adaptation switch is not enabled, or the configured
UPLOAD_FILE_MAX_SIZEis smaller than the size of a single daily report file, resulting in silent interception after upload. - Symptom: When batch uploading multiple kitchen and bathroom appliance financing daily reports to version 4.9.2, parsing interrupts mid-process, and restarting Docker does not resume parsing. Cause: This version has a memory leak issue with batch parsing, and does not limit the number of documents processed per batch, leading to system memory exhaustion.
- Symptom: Parsed chunked content truncates the financing party's kitchen and bathroom product line information, making it impossible for subsequent links to associate the corresponding project. Cause: The set
chunk_sizeis too small, leaving insufficient characters to accommodate multiple product line fields and financing details for a single project.
How to Verify Proper Configuration
- Upload a single kitchen and bathroom appliance financing daily report Excel file of normal daily file size, check if the backend parsing log generates complete field parsing records.
- Batch upload multiple daily report documents, confirm that parsing progress has no abnormal interruptions, and the backend has no memory overflow or timeout related errors.
- View the chunked text content, confirm that each chunk contains complete associated information for a single financing project, with no field misalignment or truncation.
- Trigger a large model query for specified financing project information, confirm that the returned content includes kitchen and bathroom appliance product line and financing amount details from the parsed documents.
