What the Data for This Category Looks Like
Telecommunications service industry financial report data comes from public periodic reports filed by listed companies, including annual, semi-annual, and quarterly reports. Core operating data is updated quarterly. Annual reports include complete financial and business operation data. Most documents are in PDF format, with structured financial statement sections and business operation data sections. Unique fields include mobile user count (unit: ten thousand households), ARPU value (unit: yuan per household per month), mobile internet traffic (unit: TB per month), total number of base stations (unit: units), and some reports also include segmented business fields such as roaming revenue and dedicated line revenue.
Constraints Imposed by These Characteristics on Deployment and Upgrade
Single telecommunications service financial report documents can be dozens of pages long, with individual text lengths exceeding 10,000 characters. Context processing and parsing timeout parameters must be adjusted. Unique business fields require customized extraction logic, and a field whitelist must be configured to limit the extraction scope. The quarterly update frequency requires deploying a scheduled pull and incremental synchronization mechanism to avoid repeated full data pulls. Multi-data source integration requires optimizing the chunking strategy for vector recall to ensure recall accuracy for core fields. Adapting Qwen3 series models requires matching vllm versions; lower version deployment tools may experience model loading errors, so version compatibility must be verified in advance.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–16000 characters | The average length of a single annual telecommunications service financial report can reach 12,000 characters, which needs to cover complete financial statements and business sections |
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Multi-page PDF parsing includes structured financial statements and business data, so sufficient parsing time must be reserved |
vllm_deploy_version | 0.10.0 and above | Adapts the inference logic for Qwen3 series models, resolves field extraction errors in lower versions |
RECALL_TOP_N | Top 10–15 entries | Telecommunications service financial reports include multiple segmented business fields, so enough relevant context fragments need to be recalled |
FIELD_EXTRACT_WHITELIST | Mobile User Count, ARPU, Mobile Traffic Revenue, Base Station Count | Accurately extract unique core business fields from telecommunications service financial reports, avoid redundant extraction |
UPLOAD_FILE_MAX_SIZE | 500 MB | Covers the PDF file sizes of annual/quarterly financial reports for most listed telecommunications service companies, with reasonable headroom |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing.
Three Common Configuration Mistakes
- Phenomenon: When deploying Qwen3-14B using vllm 0.9.0, the console returns the
Unrecognized model architectureerror. Cause: vllm 0.9.0 does not adapt to the new inference logic of Qwen3 series models, and cannot correctly load model weights. - Phenomenon: When extracting fields from telecommunications service financial report PDF parsing results, the
ARPU值field is empty. Cause: The unique business field is not configured in theFIELD_EXTRACT_WHITELIST, so the model does not recognize the target extraction item. - Phenomenon: A
400 Bad Requesterror occurs when calling the Qwen3-Embedding-8B model interface. Cause: The interface path and request headers for the embedding model are not correctly configured, resulting in connection abnormalities.
How to Confirm Successful Configuration
- Upload a test telecommunications service financial report PDF, check if the parsed text includes complete balance sheet, income statement, and business operation sections to verify that the document parsing configuration is effective.
- Call the locally deployed vllm model interface, input the identifier of the Qwen3 series model, check if the returned model loading logs include compatible version information to verify that the deployment version is correct.
- Configure a field extraction task, specify the preset business field list, check if the extraction results only include the unique telecommunications service business fields in the list to verify that the whitelist configuration is effective.
- Send test text to the Qwen3-Embedding-8B model interface, check if vector data that meets dimension requirements is returned to verify that the embedding model connection is normal.
