What Data for This Category Includes
Data for this category comes from concentrate and auxiliary material analysis, DCS systems, cell voltage and current monitoring, laboratory testing, energy and environmental monitoring. Daily documents include batching lists, smelting records, electrolytic cell condition records, laboratory reports, anode and cathode quality records, and environmental protection ledgers. Most document fields are process parameters, weight, temperature, current, and grade values, with units including tons, degrees Celsius, volts, amperes, and others. Update frequency runs in real time with each batch of raw materials, each furnace, or each cell operation. Each single document records complete operation data for a single batch or single cell.
Constraints Imposed by This Category’s Characteristics on Document Parsing and Chunking
The multi-source collection, high-frequency real-time updates, and specialized field characteristics of this category impose multiple constraints on document parsing and chunking. Diverse specialized documents require accurate identification of industry-specific terms and specific fields to avoid parsing errors. Single documents with high-frequency real-time updates have large fluctuations in data volume, so parsing tasks must adapt to different lengths. Cross-document business correlations (such as the linkage between batching lists, smelting records, and electrolytic cell condition records) require retaining contextual associations during chunking to prevent key business logic from being split apart. Real-time requirements also limit parsing duration to avoid delaying ledger summary progress.
Configuration Settings
These configurations are based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the length of specialized paragraphs in documents of this category, avoiding splitting complete single process parameter records |
chunkSplitter | By paragraph + specialized term boundary | Retains the integrity of specialized paragraphs such as batching, smelting, and cell conditions, adapting to the structural characteristics of industry documents |
customPdfParse | Enabled | Preserves original typesetting and field positioning for PDF-format ledgers of this category, such as official laboratory reports and environmental protection ledgers |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the parsing duration of single large smelting or electrolytic cell condition documents, avoiding parsing failure due to timeout |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Supports batch uploading of multiple batches of raw material analysis and operation record documents, meeting the batch requirements for ledger summary |
chunkSettingMode | Manual configuration | Adapts to the special parsing needs of specialized documents of this category, avoiding parameter adaptation deviations from automatic mode |
Three Common Misconfigurations
- Parsing tasks fail to read uploaded PDF or DOCX documents, and the interface shows file not found or parsing failed. The cause is incorrect configuration of the file upload directory, making it impossible to locate the storage path of ledger documents for this category.
- Audio and video files have no valid content after parsing, and chunking results are empty or only contain garbled text. The cause is that the adapted VLM model parsing is not enabled for this scenario, and parsing configuration for audio and video files is not supported.
- Chunking results split cross-operation associated data. Chunks of batching lists and smelting records for the same batch are scattered across different segments. The cause is that
chunkSplitteris configured to split by fixed characters, without retaining the boundaries of business paragraphs.
How to Verify Configurations Are Correct
- Upload a typical electrolytic cell condition record PDF document, and check if the parsed text fully retains specialized fields such as cell voltage and current strength.
- View the parsing task logs to confirm no timeout errors occur, and that the duration matches the value set for
PARSE_FILE_TIMEOUT_SECONDS. - Check the chunked text segments to confirm that associated paragraphs between batching lists and corresponding smelting records are not split apart.
- Test pushing files to the knowledge base via an external system, and confirm that files can be automatically parsed and chunked, supporting subsequent chat access.
- Test uploading audio and video files, and confirm that parsing results meet expectations (if VLM model parsing is enabled).
Note: The configuration values listed above are common starting points. They should be evaluated against the reader's own specific samples.
