What this category of data looks like
Data for this category mainly comes from the national government service platform's "One Thing" special zone, local integrated government service platforms, electronic certificate repositories, and departmental approval systems. The update frequency is daily. Daily processed documents include joint handling item lists, one-time notice sheets, joint handling application forms, material circulation sheets, parallel approval opinions, completion receipts, and party building learning content such as requirements for party building-led joint handling and party member service rules. Documents contain fields including item number, lead department, co-handling department, material requirements, and processing associated nodes. Some documents also embed HTML-format interface instructions or stamped PDF materials.
What constraints do these characteristics impose on the document parsing and chunking link
Documents contain cross-departmental business associated fields and original party building policy text. When chunking, the front-back relationship of items, material reuse rules, and complete semantics of original policy text must be retained. Splitting cross-departmental business logic and party building learning content must be avoided. Document sources include HTML-format interface documents and PDF materials with images, so support for non-plain-text format parsing and text extraction from images is required. High-frequency documents updated daily require controlling the parsing duration per file to prevent update task failures due to timeouts. Additionally, joint handling documents have certain non-standard structural characteristics, so flexible chunking rules must be adapted, and fixed character length should not be used as the only chunking basis.
How to configure the settings
The following configuration items are all parameters supported by FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the single-paragraph content length of joint handling item lists, one-time notice sheets, and original party building policy text, retaining complete semantics of cross-departmental associations and party building learning content |
chunkSplitter | Chunk by document structure | Adapts to the fixed business structure of joint handling documents, avoiding splitting the front-back association logic of cross-departmental items and original party building policy text |
customPdfParse | Enable image text recognition | Adapts to PDF files containing approval opinion stamps and material samples in joint handling documents, extracting text content embedded in images |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the parsing duration of joint handling documents containing multi-department materials, avoiding parsing timeouts for high-frequency updated documents |
chunkSettingMode | Manual configuration | Adapts to the non-standard business structure of joint handling documents, flexibly adjusting chunking rules to match actual business needs |
Three common misconfigurations
- Uploading HTML interface documents generated by javadoc results in no parsing output: The cause is that HTML tag parsing configuration is not enabled. The default setting only parses plain text format and cannot recognize the embedded interface document structure of HTML.
- Uploading PDF documents containing images fails to retrieve text within images: The cause is that the image recognition switch for
customPdfParseis not enabled. The default setting only extracts plain text content from PDF pages. - Parsing a joint handling material circulation sheet larger than 5MB results in a timeout: The cause is that the value of
PARSE_FILE_TIMEOUT_SECONDSis not adjusted. The default timeout duration is insufficient to complete complete parsing of multi-department associated content.
How to confirm the configuration is correct
- Upload a single HTML-format joint handling item list, check if the parsed text content retains the original document's title and list hierarchy structure.
- Upload a PDF approval opinion document containing stamped images, verify if the parsed result includes handwritten or printed text content within the images.
- Upload a joint handling material circulation sheet under 10MB, confirm that the parsing task completes within 10 minutes with no timeout error prompts.
- Retrieve joint handling policy content related to party building, verify that the retrieved results include complete original policy text paragraphs.
