What Data for This Category Looks Like
Telecommunications services industry financial report data primarily comes from domestic and overseas stock exchange disclosure platforms and official corporate investor relations sections. Updates follow a quarterly cadence, with full semi-annual and annual reports released concurrently. Most documents are in PDF format, some include editable text and embedded tables. Fixed core fields include financial summaries, revenue breakdowns (segmented into fixed and mobile communications, value-added services, 5G services, etc.), user scale, ARPU value, and other core fields. Field units include RMB yuan, ten thousand yuan, hundred million yuan, ten thousand households, yuan per user per month, and others. There is no unified typesetting format.
Constraints Imposed on the Knowledge Base Retrieval and Recall Workflow
The multi-source, non-standardized format of telecommunications services financial reports requires retrieval systems to support multi-format parsing and structured field extraction, to avoid text loss caused by scanned documents. The quarterly high-frequency update cycle requires knowledge bases to support incremental synchronization mechanisms, to avoid resource consumption from full updates. Multi-dimensional segmented business fields require retrieval to accurately match business types and units, to prevent mismatches between ARPU values and user counts. The long length of individual documents requires the recall stage to pinpoint specific chapters, to avoid returning irrelevant full text.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Telecommunications services financial report PDFs typically include multiple pages of tables and images, with long parsing times. 300 seconds covers the parsing needs of most individual financial reports |
chunk_size | 1000–1200 characters | Financial reports contain large numbers of structured tables and long paragraphs. This range preserves field association, and avoids breaking data integrity during splitting |
recall_top_k | Top 8–10 results | Telecommunications services financial reports have many segmented dimensions. A sufficient number of recalled entries is needed to cover query needs across different business segments |
similarity_threshold | 0.75–0.85 | Financial report content is highly specialized. A higher threshold filters irrelevant industry-general documents, while retaining results related to segmented businesses |
rerank_top_n | Top 3–5 results | Reranking increases processing time per result. Limiting the number of returned entries balances response speed and result relevance |
UPLOAD_FILE_MAX_SIZE | 500 MB | Individual annual financial report PDFs typically do not exceed 200 MB. This value reserves space to support batch uploads of multiple financial report documents |
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 individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Symptom: After enabling
rerank_top_nand optimizing queries, the API returns a 504 status code or takes more than 30 seconds to respond. Cause: Telecommunications services financial reports have long documents and many fields. The reranking model must process a large number of recalled entries, exceeding default timeout settings. - Symptom: After calling the HTML content upload API, the corresponding title and content do not appear in the knowledge base. Cause: The API request header parameters were not configured correctly, or the passed HTML content does not contain valid text nodes.
- Symptom: Retrieval results include financial report content from non-telecommunications services industries. Cause: The
similarity_thresholdwas set too low, failing to filter cross-industry general financial documents.
How to Verify Correct Configuration
- Upload a test telecommunications services financial report PDF, and check if the parsed text includes core fields such as revenue and user count, with no missing content or garbled text.
- Submit a query containing segmented business keywords, verify that the relevance of the recalled results meets expectations, and that the number of returned entries matches the configured
recall_top_kvalue. - Enable the reranking function, submit batch queries, record response times, and confirm that the times fall within a reasonable range.
- Call the conversation export API, export the specified conversation content, and confirm that the export format matches the configuration, with no missing content.
