Document Parsing and Chunking for Software Development

What this category of data looks like

Data for this category is sourced primarily from public annual and quarterly financial report PDFs and HTML attachments of software development enterprises, supporting R&D expense detail documents, and interface HTML documents generated by Javadoc. The update schedule follows quarterly releases for quarterly reports, annual releases for annual reports, with temporary announcements published as needed.

Document structures include page headers and footers, multi-dimensional tables (such as R&D cost breakdown, project revenue proportion), embedded charts, and footnotes. HTML versions include tables and images with structured tags. Javadoc-generated documents contain class names, method signatures, parameter descriptions, and other structured content.

Fields covered include R&D expenditure amounts, project revenue proportions, API call volumes, and some fields have clear units such as ten thousand yuan and calls.

What constraints these characteristics impose on the document parsing and chunking stage

These characteristics impose clear constraints on the document parsing and chunking stage.

Fixed headers and footers in financial report PDFs introduce irrelevant content. Specified regions must be excluded during parsing. Cross-page table content is truncated by page breaks. Table boundaries must be identified and cross-page fragments merged during chunking.

Embedded charts and their accompanying explanatory text are often separated. Associations must be established after parsing to avoid split information after chunking.

Javadoc-generated HTML has structured tags. Hierarchical relationships between classes and methods must be preserved. Chunking should not disrupt the correspondence between code blocks and functional modules.

High-frequency updated batch documents increase parsing pressure. Reasonable timeout and sharding settings must be implemented.

How to Set Configurations

Configuration Item	Recommended Value	Rationale
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Software development financial report documents contain multi-page tables and charts, with long parsing times. 600 seconds covers parsing requirements for most documents
`CHUNK_SIZE`	`800–1200 characters`	Financial report documents contain a large number of structured tables and long text passages. This range balances content integrity and recall accuracy
`CHUNK_OVERLAP`	`100–150 characters`	Cross-page tables and chart descriptions require contextual association. The overlap interval retains key connecting information to avoid content breaks after chunking
`PARSE_IGNORE_HEADERS_FOOTERS`	`Enabled`	Headers and footers of financial report documents contain fixed irrelevant content such as page numbers and enterprise names. Enabling this setting removes interfering information
`PARSE_TABLE_MERGE`	`Enabled`	Cross-page table content is split by page breaks. Enabling this setting merges cross-page fragments of the same table to ensure data integrity
`PARSE_HTML_STRICT_MODE`	`Disabled`	Javadoc-generated HTML has non-standard tag structures. Disabling strict mode supports parsing more structured content and avoids parsing failures

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 Mistakes

Symptom: After Javadoc-generated HTML interface documents are uploaded, the knowledge base has no parsing results or only displays a small amount of meaningless content. Cause: PARSE_HTML_STRICT_MODE is enabled. The strict mode cannot accommodate non-standard HTML tag structures generated by Javadoc, which interrupts the parsing process.
Symptom: After financial report documents are uploaded using chunk mode via the pushdata API, the interface displays the "Indexing" status long-term with no progress updates. Cause: The PARSE_FILE_TIMEOUT_SECONDS parameter is not adjusted. The default timeout period is insufficient to complete parsing of multi-page financial report documents, causing the parsing task to be forcibly terminated.
Symptom: After a financial report PDF containing embedded charts is uploaded, the parsed chunked content does not associate the text descriptions of the charts, or chart-related information is lost. Cause: The PARSE_TABLE_MERGE configuration is not enabled. Cross-page chart descriptions and main content are split by page breaks and not merged, resulting in incomplete information after chunking.

How to Confirm Correct Configuration

A small Javadoc-format HTML interface document may be uploaded. Parsed chunked content can be reviewed to confirm retention of the hierarchical relationship between class names and method signatures, and that the configuration status of PARSE_HTML_STRICT_MODE matches preset settings.
A financial report PDF containing cross-page tables may be uploaded. Parsed chunked content can be reviewed to confirm merging of cross-page table content, and that the PARSE_TABLE_MERGE configuration is effective.
Parsing task logs can be reviewed to confirm that parsing time does not exceed the duration set by PARSE_FILE_TIMEOUT_SECONDS, with no timeout error messages.
A financial report PDF containing embedded charts may be uploaded. Parsed chunked content can be reviewed to confirm inclusion of text descriptions corresponding to charts, and that irrelevant header and footer content has been filtered out.
