Policy and Regulatory Basis Q&A for Power Generation Equipment Manufacturing: Document Parsing and Chunking

Policy and Regulatory Basis Q&A for Power Generation Equipment Manufacturing: Document Parsing and Chunking

What the data for this category looks like

This data primarily comes from power generation equipment manufacturing industry policies issued by the National Energy Administration and the Ministry of Industry and Information Technology, technical standard documents developed by industry associations, and internal corporate compliance documents. Updates occur irregularly, with new or updated documents added when policies are revised or standards are updated. Most documents follow formal official document formats, including document numbers, release dates, applicable equipment type sections, embedded technical parameter tables, with fields including equipment model, rated power, detection cycle, etc., and units mostly including kilowatts, hours, tons, and similar units.

Constraints on document parsing and chunking

Policy documents for power generation equipment manufacturing have formal official document formats and embedded tables, which impose multiple constraints on document parsing and chunking. Redundant information such as headers, footers, and document numbers in formal official documents will interfere with core content extraction, requiring precise filtering. Embedded technical parameter tables contain bound fields and units. When chunking, the contextual association of cells must be retained to avoid separating parameters from their units. Irregularly updated documents require incremental parsing support to avoid repeated processing of already parsed content. Long documents may contain cross-page policy clauses. When chunking, each chunk must contain complete clause units to avoid splitting critical policy requirements.

Configuration settings

The following configurations apply to FastGPT v4.17.0.

Configuration ItemRecommended SettingRationale
chunkSize800–1200 charactersMost policy documents for power generation equipment manufacturing contain long clauses and table parameters. 800–1200 characters can cover a complete single policy clause and avoid splitting critical parameters
chunkSplitterLayered by paragraph + titlePolicy documents have clear section titles and clause paragraphs. Splitting in this way ensures each chunk has complete logical content
customPdfParseEnable header/footer filtering + table binding parsingPolicy documents contain redundant header/footer information such as document numbers and issuing institutions. Enabling filtering improves parsing accuracy, and table binding preserves the association between fields and units
UPLOAD_FILE_MAX_SIZE1000 MBA single industry policy compilation may include multiple related files. 1000 MB covers conventional bulk upload requirements
PARSE_FILE_TIMEOUT_SECONDS600 secondsParsing large policy compilation documents takes a long time. 600 seconds ensures complete parsing without timeout
chunkSettingModeManual configurationThe table and parameter structures of power generation policy documents are special. Manual configuration allows precise adjustment of chunking rules

Three common configuration mistakes

  • Phenomenon: After uploading a policy compilation file larger than 10 MB, more than 1000 chunks are generated, some chunks fail vectorization, and the interface displays the "chunk embedding failed" error. Cause: The chunkSize is not adjusted to fit the long clauses of the policy documents, the chunk size does not match the input dimension of the vector model, or the retry mechanism is not triggered correctly.
  • Phenomenon: When parsing technical parameter tables in policy documents, fields and units are split into different chunks, and subsequent Q&A cannot associate parameters with their corresponding units. Cause: The table binding parsing function of customPdfParse is not enabled, and the contextual association of table cells is not retained during chunking.
  • Phenomenon: When uploading multiple policy files in bulk, the parsing task times out, and the interface displays the "parse timeout" status code. Cause: PARSE_FILE_TIMEOUT_SECONDS is not adjusted to a duration matching the document size, or unnecessary parsing preprocessing steps are not turned off.

How to verify correct configuration

  • Upload a single typical power generation equipment policy document, check the generated chunk list, and confirm that each chunk contains complete policy clauses or table units.
  • Trigger the parsing task, check the task logs and interface prompts, and confirm that the "chunk embedding failed" or "parse timeout" errors do not appear.
  • Export the parsed chunk data, and verify that the fields and units of the embedded technical parameter tables are fully bound and not split into different chunks.
  • Upload bulk policy compilation files, and confirm that the total size of the uploaded files does not exceed the configured UPLOAD_FILE_MAX_SIZE threshold.
