What the data for this category looks like
Telecom equipment investment research data sources include 3GPP standardized technical documents, public financial reports and technical white papers from equipment manufacturers, carrier procurement bidding announcements, third-party telecom equipment performance test reports, and Ministry of Industry and Information Technology industry monitoring data. Update cadence varies by data type: standardized documents are updated with version iterations, financial reports and procurement announcements are released quarterly or monthly, and test reports are updated irregularly alongside equipment iterations. Document structure includes three categories: structured parameter tables, long-form technical descriptions, and project bidding details. Fields cover device model, radio frequency band, transmission bandwidth, power consumption indicators, deployment cost, operation and maintenance cycle, and more. Units include dBm, Mbps, units/sets, ten thousand yuan, and others.
What constraints do these characteristics create for the knowledge base retrieval and recall process
Data sources are scattered and have large format differences, including both structured parameter tables and long-form technical descriptions, so targeted parsing and recall rule configuration is required. Update frequencies are inconsistent, so incremental update support is needed to balance data timeliness and computing resource consumption. Document length varies widely, from a few pages of manufacturer financial reports to dozens of pages of standardized documents, creating differentiated requirements for text segment length. There are many field dimensions and high precision requirements, so field-level precise retrieval support is needed to avoid invalid results from fuzzy matching.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall count | 10–15 | Telecom equipment investment research data includes multi-dimensional technical parameters and project information. A single result needs to cover sufficient details; too many results will increase context redundancy |
similarity threshold | 0.72–0.85 | Telecom equipment technical parameters have high precision requirements. A threshold that is too low will include irrelevant parameter documents, while a threshold that is too high will omit matching qualified sub-model data |
segment length | 800–1200 characters | If a single segment of 3GPP standard documents is too long, context association will be lost; if too short, complete expression of technical parameters will be disrupted. This range adapts to long-form technical document splitting |
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Large 3GPP standard documents take a long time to parse. Adjusting the timeout period can avoid import failures for large-volume documents |
structured field index toggle | Enabled | Telecom equipment investment research data includes structured fields such as device model and radio frequency indicators. Enabling this supports precise field-level retrieval and improves recall accuracy |
reranked return count | Top 5 | Investment research decisions need to prioritize matching core technical parameters and project cases. Returning the Top 5 results after reranking allows quick location of valid information |
The parameter values provided on this page are all 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 your own samples before finalizing settings.
Three Common Mistakes
- Symptom: Knowledge base retrieval response time exceeds 20 seconds, and the backend log returns the
ETIMEDOUTerror code. Cause: The segment length and recall count have not been adjusted for long-form technical documents, leading to loading excessive redundant data during a single retrieval. - Symptom: The exported dataset.csv file only contains the index column, and the content field is empty. Cause: The table content extraction toggle was not enabled during document parsing, so parameter tables and structured field content in telecom equipment documents were not captured.
- Symptom: When importing large 3GPP standard documents, the page progress bar keeps refreshing and cannot complete import verification. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted, and parsing of large-volume documents timed out, triggering a repeated loading loop.
How to Confirm the Configuration Is Correct
- Initiate a retrieval for a specific telecom equipment model, and check that the response time of the returned results meets expectations.
- Export the dataset.csv file of the knowledge base, and check that the content column contains valid content such as device parameters and technical indicators.
- Import a single standardized document with more than 100 pages, and confirm that the import progress bar loads normally without continuous refreshing.
- Check the structured index status in the knowledge base backend, and confirm that fields such as device model and radio frequency indicators have been successfully indexed.
