Document Parsing and Chunking for Feed Industry Investment

What the data for this category looks like

Feed industry investment research data comes from public reports issued by industry associations, annual reports of listed feed enterprises, spot market price ledgers, policy documents from agricultural and rural affairs authorities, and third-party research notes. The update rhythm of this data varies significantly: spot raw material prices are updated daily, industry supply and demand weekly reports are released weekly, enterprise annual operating reports quarterly, and policy documents are released as needed. Document formats include structured tables such as raw material price lists and formula ratio sheets, long-form research reports, PDF industry whitepapers, and CSV-format inventory statistics files. Field units cover yuan/ton, ten thousand tons, parts by weight, and other units. Some data includes identifiers such as origin and batch number.

Constraints on document parsing and chunking from these characteristics

Multi-source, heterogeneous document formats require the parsing process to support structured tables, long-form research reports, and bulk CSV files at the same time. This prevents structured content from being split into meaningless fragmented characters. Frequently updated spot data requires parsing with low-latency batch processing. Otherwise, the business update rhythm cannot be matched. Diverse units and field identifiers require the parsing process to retain contextual associations. This avoids losing key identifiers such as units and origin after chunking. Mixed-format document flows require distinguishing between long text and structured chunks. Using uniform chunking rules will damage the integrity of structured content such as tables and formula ratios.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`PARSE_FILE_TIMEOUT_SECONDS`	`300 seconds`	Large PDF research reports or bulk CSV inventory files from the feed industry typically complete parsing within 5 minutes. This value covers processing durations for most conventional documents
`maxChunkSize`	`800–1200 characters`	The body paragraph length of feed research reports mostly falls within this range. This balances retrieval accuracy and contextual integrity
`chunkOverlap`	`100–150 characters`	Retains contextual associations across chunks, avoiding loss of key information such as consecutive dates for raw material prices or continuous formula ratios after chunking
`PARSE_TABLE_ENABLE`	`enabled`	A large number of structured tables such as raw material prices and formula ratios exist in feed industry documents. Enabling this option fully retains the row and column structure of tables
`UPLOAD_FILE_MAX_SIZE`	`1000 MB`	Adapts to the upload requirements of large industry whitepapers and bulk inventory statistics files, preventing parsing failures due to oversized files
`PARSE_CSV_USE_HEADER`	`enabled`	The headers of CSV files usually include core information such as raw material names, prices, and origins. Retaining this information improves the semantic relevance of chunked content

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. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.

Three Common Misconfigurations

Phenomenon: The parsing API returns a 408 Request Timeout status code, or the interface displays a parsing timeout. Cause: The PARSE_FILE_TIMEOUT_SECONDS parameter was not adjusted. The default value is too low to handle large feed industry research reports or bulk CSV files.
Phenomenon: After enabling the document enhanced parsing feature in v4.9.0, the parsing result is empty or contains garbled characters. Switching to v4.8.20 or using marker parsing restores normal functionality. Cause: The enhanced parsing module in v4.9.0 has insufficient compatibility with some older-format feed industry PDF research reports. It does not adapt to the font and layout structure of older documents.
Phenomenon: Table content in chunked content is split into scattered text lines with no table structure association. Cause: The PARSE_TABLE_ENABLE configuration was not enabled. This causes structured tables to be parsed and split as plain text.

How to Verify Correct Configuration

Upload a typical feed industry CSV price file. Check if the parsed structured fields include header information such as raw material name, price, and origin. Verify that the PARSE_CSV_USE_HEADER configuration is active.
Upload a feed research report PDF containing tables. Check if the parsing result retains the row and column structure of the table. Confirm that the PARSE_TABLE_ENABLE configuration is enabled.
Upload multiple feed documents of different formats in bulk. Check if parsing time aligns with the business update rhythm. Verify the rationality of the PARSE_FILE_TIMEOUT_SECONDS parameter setting.
Adjust the maxChunkSize parameter, then retrieve chunked content. Confirm that overlapping contextual information exists between adjacent chunks. Verify the effect of the chunkOverlap configuration.
