What Data Looks Like for This Category
Data sources include daily production ledgers of aquaculture entities, daily price summaries from regional aquatic product buyers, and daily financing application submissions. Full daily data is updated at a fixed time each day. Most documents are structured Excel sheets or PDF reports with fixed headers. Fields include: pond ID, aquaculture species, pond area, total daily feed input, daily average purchase price, daily financing application amount, and approval status. Their respective units are: none (for ID), species name, mu, kilogram, yuan/kg, ten thousand yuan, and text status. A small number of documents include handwritten or electronic abnormal explanation remarks.
Constraints Imposed by These Characteristics on Document Parsing and Chunking
High proportions of structured tables with fixed headers require accurate matching of fields to corresponding values to avoid misaligned parsing. Multiple units coexist in fields, so chunking must retain the binding between fields and their units to prevent data ambiguity during retrieval. Documents are added in batches daily, so the workflow must adapt to high-frequency batch parsing and chunking. A small amount of unstructured remark content must be bound to adjacent structured fields during chunking to avoid separating core data from supplementary explanations. The core financing amount field must be prioritized within chunk boundaries to prevent truncation and loss of critical information. Field details vary across aquaculture species, so chunking must retain the association between species and corresponding data to avoid mixing data across species.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1000 characters | A single complete structured entry for aquaculture financing daily reports is approximately 100 characters. This length can accommodate 7–10 complete entries, avoiding splitting cross-entry headers and data |
chunk_overlap | 100–150 characters | Must retain field associations across adjacent chunks, such as the contextual connection between pond ID and daily financing amount, to prevent loss of cross-chunk associated information during retrieval |
parse_table_mode | structured_only | Aquaculture financing daily reports center on structured tables. Prioritize parsing table fields and ignore unstructured page headers and footers to improve parsing accuracy |
batch_parse_max_count | 20–30 documents per batch | The number of newly added documents each day is stable. Batch processing balances parsing efficiency and server load |
field_mapping_threshold | 0.85 | Must accurately match headers to field names, avoid field misalignment caused by minor header differences, and ensure the integrity of chunked data |
max_context_retention | Previous 3 adjacent chunks | Core data for aquaculture financing daily reports relies on the context of the daily overall ledger. Retaining adjacent chunks improves the contextual completeness of retrieval |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Errors
- Symptom: The core financing amount field is empty in parsed chunks. Cause: Structured parsing mode for
parse_table_modewas not enabled, and table content was recognized as plain text, preventing correct extraction and binding of fields. - Symptom: Contextual references display unrendered Markdown source code. Cause: Table format markers from the original document were not retained during chunking, or the parsing process did not correctly convert table structures to renderable formats, leading to failed rendering during reference display.
- Symptom: Adjacent pond ID and financing amount fields are split into different chunks after chunking. Cause:
chunk_overlapvalue was set too low, and insufficient contextual overlap was retained, cutting off cross-field associations.
How to Verify Proper Configuration
- Upload a standard Excel document for aquaculture financing daily reports, check the parsed field list to confirm core fields such as pond ID and financing amount have been correctly identified.
- View the chunk preview interface to confirm each chunk contains complete structured entries with no cross-field splitting.
- Simulate batch upload of 10 daily documents to confirm the parsing and chunking workflow has no timeouts or error prompts.
- Trigger a contextual reference test to confirm referenced content renders correctly into readable format, with no raw source code displayed.
