What the data for this category looks like
Documents for water treatment marketing content originate primarily from equipment manufacturers’ product manuals, project implementation case reports, industry technical specifications, and marketing promotional materials. Their update schedule shifts irregularly alongside product iterations, new project launches, and standard revisions. Most documents combine text and images, including structured parameter tables and scenario description paragraphs. Fields include equipment model, treatment capacity, operating pressure, and applicable water quality indicators. Common units include cubic meters, megapascals, hours, and other engineering units.
Constraints for the document parsing and chunking workflow
Water treatment marketing documents have a high proportion of structured parameter tables. During parsing, avoid splitting cross-row and cross-column parameter tables into scattered text chunks. This prevents broken parameter associations during subsequent retrieval. In mixed text and image scenario descriptions, equipment parameter descriptions often accompany corresponding schematic diagrams. During chunking, retain the contextual binding between text and images. This avoids situations where parameters lack corresponding descriptions during retrieval. Standardized use of engineering units requires retaining the binding between units and parameters during chunking. This prevents numerical values and units from being separated during retrieval. Irregularly updated documents require support for incremental parsing workflows. This avoids resource consumption caused by full repeated parsing.
How to configure the workflow
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Water treatment documents often contain lengthy project case paragraphs and detailed parameter tables. Single-file parsing takes extended time. 600 seconds covers most single-file parsing needs |
maxChunkSize | 800–1200 characters | Parameter tables and scenario descriptions in water treatment documents vary widely in length. This range balances parameter binding and contextual completeness |
PARSE_ENABLE_TABLE_EXTRACT | Enabled | Structured parameter tables in water treatment documents are core retrieval content. Enabling this setting extracts full table content and prevents loss of parameter data |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Large project case documents may include multiple parameter tables and accompanying images. 1000 MB covers upload requirements for most commercial documents |
chunkOverlap | 100–150 characters | Parameters and scenario descriptions in water treatment documents are closely linked. Overlap ranges ensure contextual associations are not interrupted |
PARSE_IMAGE_INCLUDE | Extract alt text only | Accompanying images in water treatment documents are mostly equipment schematics. Alt text already includes core parameter descriptions, so no additional processing of image binary content is required |
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 case-by-case analysis. It is recommended to test on appropriate samples before finalizing settings.
Three common errors to avoid
- Symptom: When deploying version 4.8.21 via Docker, slow operation xxxxms warnings appear continuously in logs during parsing of uploaded water treatment documents. Cause: Water treatment documents contain multiple large parameter tables and lengthy project description paragraphs. The default parsing timeout threshold does not align with the parsing time required for this type of document, triggering timeout warnings.
- Symptom: When uploading a DOCX-format water treatment marketing document with embedded images, a File: <Content> Invalid image file error is returned. Cause: The encoding format of embedded images in the document is not supported by the default parsing module, or the temporary image directory was not correctly mounted during container deployment. This prevents the parsing process from reading supplementary text associated with the images.
- Symptom: When parsing a PDF-format water treatment marketing document, only plain text content is extracted, and parameter descriptions corresponding to images are not linked. Cause: The PDF text-image binding parsing configuration was not enabled, so supplementary descriptions for accompanying images are not included in the chunked content.
How to confirm the configuration is properly set up
- Upload a single water treatment document containing multiple sets of parameter tables. Check that no timeout-related warnings appear in parsing logs, to confirm the parsing timeout configuration matches the parsing time required for the current document.
- Upload a DOCX-format document with embedded images. Check that parsing results fully retain text descriptions associated with images, to confirm image parsing related configurations have been correctly enabled.
- Check hardware resource monitoring on the deployment node. Confirm that multiple parallel parsing tasks can access configured graphics card resources, to confirm multi-card scheduling parameters have been correctly set.
- Retrieve chunked document fragments, confirm that equipment parameters and corresponding scenario descriptions are not split into unrelated chunks, to confirm chunk length and overlap configurations match the characteristics of the document content.
