Data Characteristics for This Category
Solid waste management marketing content data comes primarily from green project promotion brochures from financial institutions, bidding documents for solid waste disposal projects, operation manuals, environmental impact assessment approval reports, and local environmental protection policy notices. Data update cadence varies by scenario: policy documents are updated annually or quarterly, project case documents are updated alongside newly launched solid waste disposal projects, and internal operation manuals are revised every six months. Document structures include structured sections such as qualification requirements, disposal processes, and charging standards, as well as unstructured long text. Core fields include disposal scale (units: tons/day, tons/year), moisture content, degradation rate, project qualification numbers, and some documents include equipment parameters and compliance standard details.
Constraints for Document Parsing and Chunking
The multi-source and structured nature of solid waste management marketing content creates multiple constraints for document parsing and chunking. First, structured documents containing qualifications and process parameters must retain their original chapter hierarchy. This prevents loss of binding relationships between compliance clauses and corresponding parameters, and meets the compliance disclosure requirements of financial institutions. Second, individual documents can reach dozens of pages. Excessively long text exceeds model context windows, so splitting by chapter or fixed length is required. However, splitting must avoid breaking the connection between process descriptions and compliance requirements, which would destroy the core value of marketing content. In addition, core fields have dedicated units such as tons/day and degradation rate percentage. The parsing process must retain the binding between units and corresponding parameters, preventing separation of parameters and units after chunking, which would affect the accuracy of financial product promotions. Some policy documents include version identifiers. Chunking must embed version information into corresponding content blocks, ensuring that retrieval matches the latest compliance requirements.
Configuration Settings
| Configuration Item | Recommended Range | Rationale |
|---|---|---|
maxChunkSize | 800–1200 characters | Solid waste management documents often contain long process descriptions and compliance clauses. This range ensures that a single chunk contains complete process logic or compliance requirements, avoiding split damage to associated information |
chunkOverlap | 100–150 characters | Retaining overlapping content between adjacent chunks connects cross-chunk process parameter explanations, preventing loss of connected compliance details during retrieval |
preserveHeaderFooter | Enabled | Solid waste management documents frequently include metadata such as qualification numbers and project numbers. Enabling this setting retains header and footer identifier content, preventing metadata loss |
extractMetadata | Enable "disposal scale, qualification number" fields | Targeting the core fields of solid waste management documents, extracting specified metadata enables quick location of compliance qualifications and disposal capabilities of corresponding projects during retrieval |
PARSE_TIMEOUT | 300 seconds | Individual solid waste documents have long lengths. A 300-second timeout setting covers the full parsing process, avoiding file upload failures caused by parsing timeouts |
parseFileType | Restrict to .pdf, .docx | Solid waste management marketing content mostly uses these formats. Restricting parsing types reduces resource consumption from invalid parsing |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. It is recommended to test against your own samples before finalizing settings.
Three Common Configuration Mistakes
- Issue: Documents upload and parse correctly in a local environment, but trigger a 404 error when uploading files on a server deployment, and the parsing node cannot read file content. Cause: The file upload directory configuration in the server environment does not match the local environment, or the access permissions of the static resource directory are insufficient, causing the parsing node to fail to obtain uploaded files.
- Issue: When deploying Qwen3-14B using Vllm 0.10, specified fields such as disposal scale and qualification number cannot be extracted from the parsing results of solid waste management documents. Extraction works normally after switching to Qwen2.5-14B. Cause: Different large model versions have varying adaptation logic for structured field recognition. Vllm 0.10's Qwen3-14B has not been adapted to the dedicated fields of solid waste management documents.
- Issue: Parsed chunked content breaks the connection between process descriptions and compliance requirements. For example, process parameters and compliance clauses from the same chapter are split into different chunks. Cause: Chunking is not performed by chapter, and only fixed-length splitting is used, destroying the logical connection of long documents.
How to Verify Proper Configuration
- Upload a solid waste management marketing document that includes structured sections and core parameters. Review the parsed chunk list to confirm that each chunk contains complete process descriptions or compliance clauses.
- Navigate to the parsing configuration page. Verify that the set values of
maxChunkSizeandchunkOverlapmatch actual business requirements, and confirm that the metadata extraction fields include core parameters related to solid waste management. - Upload solid waste management documents in different formats such as
.pdfand.docx. Check that the parsing node's return results include correct file type recognition and metadata extraction. - Simulate a server environment deployment. Upload a test file and review the parsing logs to confirm there are no timeout or 404 error prompts.
