What the data for this category looks like
Marketing documents related to electronic components for the financial industry mainly come from manufacturer datasheets, authorized dealer quotations, industry technical white papers, and brand marketing materials. Document update cycles vary by source. Manufacturer specification documents are updated with product model iterations. Dealer quotations are adjusted based on market supply and demand. Typical document structures include specification parameter tables, pin definitions, application circuits, and compliance certification descriptions. Core fields include resistance value, capacitance value, operating temperature range, and package model. Corresponding units are ohms, farads, degrees Celsius, and package codes.
What constraints do these characteristics impose on the "document parsing and chunking" link
Marketing documents for electronic components in the financial industry have obvious structural differences across sources. Manufacturer datasheets mostly use fixed parameter formats, while marketing materials use free layouts. General parsing rules cannot cover all document types. Core parameters may use multiple units interchangeably. For example, resistance values are labeled with both milliohms and kiloohms. The association between units and numerical values must be accurately identified. Some documents embed non-text elements such as pin diagrams and circuit schematics. Parsing must retain the association between parameters and their corresponding descriptions, rather than only extracting plain text. Batch documents contain a large number of duplicate compliance certification paragraphs. Chunking must avoid redundant splits while ensuring the integrity of parameter blocks.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_FILE_MAX_SIZE | 200 MB | Single files for electronic component documents are mostly tens of megabytes. Files exceeding this threshold are mostly batch-packaged manuals. Setting this limit avoids parsing timeouts |
CHUNK_SIZE | 800–1200 characters | Electronic component parameter blocks mostly cover 300-800 characters of specifications and descriptions. Chunking must retain complete parameter units |
CHUNK_OVERLAP_RATIO | 0.15–0.2 | Associated content such as pin definitions and application scenarios exists between parameter blocks. The overlap ratio ensures contextual coherence |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Multi-page datasheets contain charts and long parameter lists. Sufficient parsing time must be reserved |
ENABLE_OCR_PARSE | Enable based on document type | Scanned marketing materials require OCR to extract text. Native PDF documents do not need this setting enabled |
FILTER_REPEAT_CONTENT | Enable | Batch documents contain duplicate compliance certification paragraphs. Filtering reduces chunking redundancy |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, 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
- The symptom is that some parameter tables or long text paragraphs are missing from the parsed knowledge base content. The cause is that OCR parsing for scanned documents is not enabled, or
PARSE_FILE_TIMEOUT_SECONDSis set too short, resulting in incomplete parsing. - The symptom is that complete parameter groups are frequently split in chunking results. The cause is that the
CHUNK_SIZEparameter is not adjusted based on category characteristics, and the default configuration for general categories is used. - The symptom is that the returned text stream does not retain the original document's hierarchical structure, appearing as unformatted continuous text. The cause is that the Markdown format retention option is not enabled, so parsed content does not retain the original document's layout information.
How to confirm correct configuration
- Upload a single typical electronic component document, view the parsed text preview, and confirm that core parameters and associated descriptions are not split or omitted.
- Batch upload multiple types of electronic component documents, check the completion status of parsing tasks, and confirm that the configuration adapts to the current document scale and format.
- Call the knowledge base query interface to retrieve specific parameter keywords, and confirm that the returned chunked content contains complete parameter groups and related descriptions.
- View the streamed text fragments, confirm that the format retains the original document's paragraph and structural characteristics, and adapts to front-end display requirements.
