What this type of data looks like
Telecommunications equipment financing daily report data is primarily sourced from industry news platforms, government and enterprise bidding announcements, official announcements from telecommunications equipment manufacturers, and financing information aggregation channels. Updates occur on a daily basis. Each daily report covers financing events from the current day and the previous three business days. Common document formats include Excel, Word, and standardized PDF. Each file contains multiple independent financing project entries, with fields including project ID, manufacturer entity, telecommunications equipment category, financing amount, financing round, disclosure date, cooperating units, and more. Amount units are typically ten thousand yuan or hundred million yuan. The equipment category field often includes detailed model parameters.
Constraints for Parsing and Chunking
Daily updated bulk entries require the parsing process to support efficient batch identification and avoid timeout for single project parsing. The structure with multiple fields and detailed parameters requires that chunking preserves the binding relationship between fields and their corresponding content, to prevent field misalignment after splitting. Single files often reach tens of megabytes and contain a large number of structured tables, which imposes constraints on the parsing engine's memory usage and processing speed. Each individual financing project in the daily report is an independent business unit, so chunking must use the project as the smallest unit. General paragraph splitting logic must be avoided to prevent business logic breakdown after splitting.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600-900 seconds | Telecommunications equipment financing daily reports often reach tens of megabytes per file and contain multiple table contents, requiring sufficient processing time to be reserved |
UPLOAD_FILE_MAX_SIZE | 20-50 MB | Daily report files are mostly Excel or Word, with single-file size within daily submission limits, to avoid upload interception |
chunk_size | 800-1200 characters | The information length of a single financing project mostly falls within this range, which can retain business integrity and retrieval relevance |
chunk_overlap | 50-100 characters | Adjacent project context must be retained to prevent critical information from breaking at chunk boundaries |
excel_split_mode | Split by row | Each row in Excel corresponds to one financing project, splitting by row ensures that a single financing project is an independent chunk |
similarity_threshold | Calibrated based on actual testing | Adapt to the keyword matching logic of financing daily reports, avoiding overly strict or loose recall rules |
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, and it is recommended to test on self-provided samples before finalizing settings.
Three Common Configuration Mistakes
- Phenomenon: After uploading a daily-sized Word-format financing report, the parsing status remains unresponsive for an extended period, eventually returning a
504 Gateway Timeouterror. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted. The default timeout period cannot cover the processing flow of large files containing a large number of structured tables. - Phenomenon: After importing an Excel-format financing daily report, automatically split chunks contain multiple rows of content, and a single financing project is split across multiple chunks. Cause: The
excel_split_modeconfiguration was not set toSplit by row. The default paragraph-based splitting logic leads to cross-project content merging. - Phenomenon: Some financing project chunks that exactly match user queries are not included in search results. Cause: The
similarity_thresholdparameter is set incorrectly, or thechunk_sizeconfiguration is too small, causing key field information matching the query to be lost within the chunk.
How to Verify Correct Configuration
- Upload a single daily-sized Word-format financing report, confirm parsing progress completes within a reasonable time frame and no timeout-related errors occur.
- Import an Excel-format financing daily report, randomly select several project entries, and verify that each chunk only contains complete information for a single financing project.
- Enter a known financing project keyword present in the daily report, perform a search operation, and confirm that the corresponding chunk is successfully recalled in the result list.
- Batch upload multiple daily report files, and confirm that the system generates independent processing units for each file, with no cross-file merging occurring.
