What Data for This Category Looks Like
Solid waste treatment investment research data is sourced from solid waste disposal ledgers and hazardous waste management permit platform data published by regional housing and urban-rural development and ecological environment departments, sampling analysis reports from third-party testing institutions, process research materials released by industry associations, and operation logs from project sites. Data update frequencies fall into three categories: real-time (project operation logs, temporary disposal notices), monthly (regional disposal volume statistics), and quarterly (industry process update reports). Document formats include plain text compliance clauses, tabular material balance and disposal parameter data, and structured permit information. Fields include disposal volume, pollutant concentration, disposal method, permit number, and other relevant items.
Constraints for Retrieval and Recall Workflow
Solid waste treatment investment research data contains a large number of structured tables and technical terms. The retrieval link must support table semantic parsing and precise matching to avoid breaking the contextual association of professional parameters. Data sources with multiple update frequencies require an update mechanism that combines incremental and full updates. This ensures timeliness of compliance documents and real-time operation data. Fields have clear unit and number identifiers. Retrieval must support filtering by field dimensions to avoid confusion between general terms and professional scenarios. Long-text process descriptions and compliance clauses require a segmentation strategy that preserves complete process logic. This prevents parameters and application scenarios from being split and losing their association.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_TABLE_ENABLE | Enabled | Solid waste investment research data contains a large number of material balance and disposal parameter tables. Enabling this setting preserves table semantic structure and improves retrieval matching accuracy for professional parameters |
Segment Length | 800–1200 characters | Solid waste treatment documents include long-text process descriptions and regulatory clauses. Excessively long segments lose contextual association, while excessively short segments break the correspondence between process logic and parameters |
Number of Retrieved Results | Top 8–12 | Solid waste investment research requires multi-dimensional reference to regional disposal quotas, compliance standards, and process solutions. Too many retrieved results introduce irrelevant content, while too few omit critical reference data |
Similarity Threshold | 0.72–0.80 | Terminology related to solid waste is highly specialized. A threshold that is too low introduces irrelevant environmental protection documents, while a threshold that is too high omits reference data for similar processes. Adjust based on actual test results |
Incremental Update Interval | Every 24 hours | Regional solid waste disposal quotas and monthly statistics are updated on a periodic basis. Incremental updates ensure timeliness of knowledge base data and reduce resource consumption from full updates |
Number of Reranked Results | Top 3–5 | Investment research decisions need to focus on core compliance requirements and process solutions. Reranking filters low-correlation retrieved results and improves information acquisition efficiency |
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. Each scenario requires individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Issue: A large number of general environmental protection documents unrelated to solid waste treatment appear in retrieval results, with unsatisfactory relevance. Cause: The
PARSE_TABLE_ENABLEsetting is not enabled, and vector matching logic is not optimized for solid waste technical terms, leading to generalized semantic matching. - Issue: A
PARSE_FILE_TIMEOUTerror is triggered when uploading large project feasibility study reports. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, and parsing time for long solid waste treatment documents exceeds the default threshold. - Issue: The knowledge base does not automatically update the retrieval index after uploading documents via API. Cause: The
AUTO_REINDEX_AFTER_UPLOADsetting is not enabled, or thereindexparameter is not included in the API call.
How to Verify Proper Configuration
- Upload a solid waste disposal document containing material balance tables, and check if the parsed segments retain table structure and field associations.
- Enter a technical keyword such as "hazardous waste incineration pollutant emission limits", and verify that the retrieved results include compliance documents and parameter data for the corresponding scenario.
- Adjust the
Similarity Thresholdand compare the number and relevance of retrieval results between the two attempts to confirm the parameter takes effect. - Call the knowledge base retrieval API, check if the
scorefield in the returned results falls within the preset threshold range, and verify that the retrieval logic is working correctly.
