What the data for this category looks like
Telecommunications service research reports primarily come from broker telecommunications industry research institutes, publicly disclosed documents from telecommunications equipment manufacturers, and monthly monitoring reports from industry associations. Update cadences cover monthly tracking, quarterly earnings report interpretations, annual strategy outlooks, and ad-hoc analyses following major industry events. Document structures typically include sections such as industry overviews, segmented track data (e.g., base station deployment volume, optical module shipment volume), financial metrics, and risk warnings. Common fields include user count (unit: 10,000 households), revenue (unit: 100 million yuan), ARPU value (unit: yuan/household), device speed (unit: Gbps), and other professional metrics.
What constraints do these characteristics impose on the document parsing and chunking workflow?
The multi-source, mostly semi-structured nature of telecommunications service research reports creates multiple constraints for document parsing and chunking. First, a single report often contains mixed formats of PDF, Word, and Excel. Excel files mostly carry structured data for segmented tracks, so accurate identification of cell and row correspondence is required. Second, reports contain a large number of professional terms and context-bound metrics (e.g., the association between optical module speed and corresponding manufacturers). Chunking must retain the complete context of metrics to avoid splitting critical information. In addition, single reports often range from several megabytes to tens of megabytes in size. The parsing process must balance completeness and efficiency to prevent timeouts or broken chunks.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale | ||
|---|---|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Telecommunications research reports are mostly large documents, requiring sufficient timeout to complete full parsing | ||
| Chunk Length | 800–1200 characters | Telecommunications research reports contain long paragraphs of industry analysis and structured data. This range can retain metric context and avoid splitting critical information | ||
| Custom Delimiters | `\n\n | ### | #### ` | Telecommunications research reports often use third-level and fourth-level titles as paragraph separators. Combining with line breaks enables accurate splitting of different module contents |
UPLOAD_FILE_MAX_SIZE | 50 MB | Single telecommunications research reports are often large in size. This threshold covers the import needs of most conventional reports | ||
CHUNK_OVERLAP | 100–150 characters | Professional terms and metrics need to retain context across chunks. The overlap length ensures complete associated information is retrieved during searches | ||
TABLE_EXTRACT_MODE | Split by row | Structured tables in telecommunications research reports are mostly monthly/quarterly data arranged by row. Splitting by row ensures each piece of data becomes an independent chunk for accurate retrieval |
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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: When uploading a Word research report larger than 10 MB, the parsing status stays for a long time and eventually returns a timeout error. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted. The default timeout duration is insufficient to complete full parsing of large research reports. - Phenomenon: When importing an Excel file containing segmented track data, the automatic splitting result merges multiple rows of data into a single chunk. Cause: The Custom Delimiters are not configured with line breaks, or the table row extraction mode is not enabled, resulting in failure to correctly split structured data.
- Phenomenon: A search request targeting a specific clear metric in a report fails to retrieve the corresponding chunk content, but normal retrieval works after creating a knowledge base with the same configuration. Cause: Chunk-related parameters are not fixed. Chunking rules differ across knowledge bases, leading to inconsistent search matching logic.
How to Verify Correct Configuration
- Upload a telecommunications research report of typical size, view the chunk list after parsing is complete, and confirm that each chunk contains complete industry metrics or paragraph content.
- Import an Excel research report containing structured tables, and check whether the chunk results are split by row, with each piece of data corresponding to a single chunk.
- After adjusting chunk-related parameters, initiate a search request targeting a clear metric in the report, and confirm that the retrieved chunk contains the complete context of the target metric.
- Upload multiple telecommunications research reports in different formats, check whether the parsing progress proceeds normally, and there are no timeout-related errors.
