What the data for this category looks like
Data for telecom service marketing content primarily comes from internal financial institution telecom marketing material systems, activity planning document repositories, and exported files from SMS and phone call script materials used for external distribution. Update cycles include regular updates for financial product promotions, as well as temporary new documents added during holidays and new service launches. Document formats include editable PDF, Word, exported official account post text, customer service script manuals, and more. Structures include product parameter tables, fee descriptions, applicable customer group rules, activity validity period descriptions, and more. Fields include product name, annualized yield, service period, activity coverage, and more. Units use standard business units such as %, yuan, days.
What constraints these characteristics impose on the document parsing and chunking stage
Multi-format sources of telecom service marketing documents from financial institutions require parsing engines to support reading multiple unstructured and semi-structured documents. Uncertain update cycles require parsing workflows to have fast response capabilities to adapt to temporary bulk import needs. Documents contain structured product comparison tables, so the chunking process must not break field relevance, and must avoid splitting content across rows and columns. Business fields have clear units and semantic attributes, so chunking must retain the binding between fields and units to prevent parameter-unit mismatches during retrieval. Long customer service script paragraphs require chunking to follow semantic logic, ensuring contextual coherence during retrieval.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
upload_file_max_size | 500 MB | Financial telecom marketing documents are mostly product descriptions and script manuals. Single files typically do not exceed 500 MB. Exceeding this size will trigger parsing failure |
max_chunk_size | 800–1200 characters | Financial telecom marketing documents include product parameters and activity rules. This length retains semantic integrity and avoids splitting cross-field content |
chunk_overlap | 100–150 characters | Retains contextual association between adjacent chunks, facilitating association between product tiers and applicable rules during retrieval |
enable_table_parse | Enabled | Financial telecom marketing documents often include product comparison tables. Enabling this setting allows complete extraction of table fields and corresponding content |
parse_timeout | 300 seconds | Large marketing documents contain multiple pages of product descriptions. 300 seconds covers the complete parsing process |
chunk_mode | semantic | Scripts and activity rules in financial telecom marketing documents require semantic chunking to avoid hard splitting that damages business logic |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Parsed content is empty after uploading some PDF documents, while other documents are recognized normally. Cause: Some PDFs only contain image-embedded scan layers and do not have embedded extractable plain text content, so the parsing engine cannot read valid information.
- Importing a Java interface document after changing its file extension to .txt results in no business content being parsed. Cause: Changing the file extension does not alter the actual code-structured format of the file. Plain text parsing rules cannot recognize business fields and logical structures within Java interface documents.
- Using
chunk_modeto call the pushdata API for upload causes the interface to remain in the indexing state for a long time. Cause: Chunking parameters are set too large, or the uploaded file size exceeds theupload_file_max_sizelimit, leading to blocked parsing and indexing processes.
How to confirm configurations are properly set
- Upload a single typical financial telecom marketing document, check the parsed chunk preview, and confirm that business fields such as product tiers and fee standards are not incorrectly split.
- Check the logs of the parsing task, confirm that no timeout-related error prompts appear, matching the current configured timeout parameter.
- Import a marketing document containing product comparison tables, confirm that the parsed result completely retains the table fields and corresponding content.
- Call the test interface to submit an upload request with chunking mode, confirm that the returned chunk results conform to the semantic logic of the business document.
