What the data for this category looks like
Feed industry financing daily report data primarily comes from public reports released by domestic animal husbandry industry associations, periodic financing announcements disclosed by listed feed enterprises, and real-time transaction data from regional animal husbandry trading platforms. Updates occur daily. Each daily report covers all industry-wide financing events from the current day. Most documents use PDF or structured table formats. They include fields such as enterprise name, financing amount (unit is mostly ten thousand yuan), financing round, corresponding feed category (such as pig feed, poultry feed, aquafeed), transaction counterparty, release date, and some documents include brief financing background notes.
What constraints these characteristics impose on the document parsing and chunking step
Daily updated batch documents require the parsing process to have efficient adaptability, to avoid excessive time spent processing single files. The mixed presence of structured fields and semi-structured notes means chunking cannot split associated information from the same financing event. For example, do not split an enterprise name and its corresponding financing amount into different chunks. The existence of segmented feed category fields requires chunking to retain contextual association, to ensure subsequent retrieval can accurately match financing information for specific categories. Single documents contain many entries, but each entry has short content. This requires avoiding merging multiple independent financing events into a single chunk, or over-splitting the complete information of a single event.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | The total length of a single financing event and its associated information is approximately 300–600 characters. This range reserves sufficient context space to avoid splitting complete events |
chunk_overlap | 100–150 characters | Retain overlapping content between adjacent chunks to prevent critical information split across segments, such as financing round and amount, from being separated |
custom_separator | , Financing Event, Enterprise Details | Matches the line break separators and event title markers commonly used in feed industry financing daily reports, ensuring each independent financing event acts as the basic chunk unit |
parser_mode | structured+markdown | Adapts to structured tables and markdown format notes in daily reports, retaining field hierarchy |
max_file_size | 50 MB | Single feed industry financing daily report files are generally smaller than 10 MB. This value reserves sufficient margin for batch upload scenarios |
parse_timeout | 300 seconds | Meets the parsing needs of daily batch documents, avoiding task failure caused by single-file processing timeout |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: After setting
custom_separator, chunks still merge multiple independent financing events. Cause: The line break\n\nwas not used as a priority separator, causing the system to fail to recognize natural paragraph breaks in the daily report. - Phenomenon: An error is returned when processing feed industry financing daily report PDFs after deploying Marker via docker, with the response
{"detail":"Error message: ..."}. Cause: Marker's environment variables were not configured correctly, or the uploaded PDF file contains encrypted content that cannot be parsed. - Phenomenon: Chunks cannot be linked to the original document, and retrieval results do not include source information. Cause: The
enable_citationconfiguration item was not enabled, or document metadata fields were not retained during chunking.
How to confirm the configuration is correct
- Upload a single test feed industry financing daily report file, view the parsed segment preview, and confirm that each independent financing event is a single chunk unit.
- Check the overlapping character count between adjacent chunks, and confirm it falls within the configured value range.
- Review the parsing task log information, and confirm there are no timeout, format error, or permission abnormality prompts.
- Initiate a retrieval for a specific feed category financing event, and confirm that the recalled results include complete associated fields and source document information.
