Declaration Materials and Dossier Review for Power Grid Enterprises: Document Parsing and Chunking

Declaration Materials and Dossier Review for Power Grid Enterprises: Document Parsing and Chunking

What Data for This Category Looks Like

Data for power grid enterprise declaration materials and dossier review originates from project declaration systems and archive management systems. Updates are uploaded in batches alongside project progress, with bulk updates during centralized review periods.

Document types include PDF engineering feasibility study reports, Word declaration forms, HTML interface documents generated by Javadoc, and some text files with modified extensions. Most documents have uniform standard headers and footers. Interface documents contain fixed class names, method names, and parameter lists. Core fields include project code, voltage level, and equipment model. Units include kV, MW, A and other power industry-specific units.

Constraints on Document Parsing and Chunking

Mixed document types with both structured and unstructured content require the parsing module to support multiple formats, particularly Javadoc HTML and text files with modified extensions.

Fixed headers and footers on some documents lead to repeated chunks or redundant content. These must be removed during the parsing phase.

The structured syntax of interface documents requires chunking rules to preserve code semantic units, avoiding disruption to professional expressions.

Significant variation exists in the sizes of batch-uploaded files, ranging from several KB interface documents to hundreds of MB feasibility study reports. The system must adapt to different upload and parsing thresholds.

Configuration Settings

Reference only; verify against the target FastGPT release and deployment documentation.

Configuration ItemRecommended ValueRationale
chunkSize800–1200 charactersPower grid declaration materials are mostly engineering long-paragraph documents. This chunk length adapts to semantic units of professional technical content, avoiding excessively long chunks that harm retrieval accuracy
chunkSplitterSemantic chunkingPower grid documents contain a large number of power industry technical terms and structured parameters. Semantic chunking preserves content integrity and avoids breaking professional expressions
customPdfParseEnabledPower grid PDF documents often have uniform headers and footers. Enabling custom parsing removes redundant identifiers and improves chunking accuracy
UPLOAD_FILE_MAX_SIZE1000 MBLarge power grid feasibility study reports can reach hundreds of MB. This setting adapts to large file upload requirements, with the upper limit calibrated via actual testing
PARSE_FILE_TIMEOUT_SECONDS600 secondsParsing large PDF and HTML interface documents takes significant time. This setting reserves sufficient time to complete the parsing process
chunkSettingModeManual configurationPower grid documents have diverse types. Manual configuration allows adjusting chunking rules for different document types, adapting to both structured and unstructured content

Three Common Misconfigurations

  • Uploading a Java interface file with a modified TXT extension results in empty parsing results. The parsing rule for code text is not enabled. When the system parses as plain text by default, it cannot recognize the syntax structure of Java code, so valid content cannot be extracted.
  • Using chunk mode to call the pushdata API for uploads causes the interface to show indexing for an extended period. A reasonable PARSE_FILE_TIMEOUT_SECONDS value is not configured, or the uploaded file exceeds UPLOAD_FILE_MAX_SIZE. This leads to parsing process timeout without completion, and the indexing task stalls.
  • Uploading an HTML interface document generated by Javadoc results in no valid parsed content. Structured parsing for HTML documents is not enabled. The system only extracts plain text by default, ignoring embedded code blocks and structured parameter lists in the HTML, leading to empty parsing results.

How to Verify Proper Configuration

  • Upload a single typical power grid engineering PDF declaration material, check the parsed chunked content. Confirm that headers and footers have been removed, and technical paragraphs are correctly split.
  • Upload an HTML interface document generated by Javadoc, verify that the parsed result includes structured content such as class names, method names, and parameter lists, with no empty fields.
  • Upload a Java interface file with a modified TXT extension, confirm that the parsed result extracts core methods and parameter information from the code, with no fully empty parsing results.
  • Upload a file close to the UPLOAD_FILE_MAX_SIZE limit, confirm that the upload and parsing processes do not trigger timeouts or errors.
