What Data Looks Like for This Category
Data for computer equipment investment research comes primarily from manufacturer public technical white papers, hardware test reports, industry standard documents, supply chain data, and hardware-related sections of quarterly earnings reports. Update frequency adjusts based on manufacturer new product launches, industry standard revisions, or supply chain changes, with no fixed cycle. Most documents include structured parameter tables, technical specification appendices, compatibility notes, and similar structures. Fields cover device model, clock speed, power consumption, storage capacity, interface type, and more. Units use standard technical units such as GHz, W, TB, pin.
Constraints Imposed by These Characteristics on Document Parsing and Chunking
The structure that ties structured parameter tables to technical descriptions means parsing cannot randomly split parameters from their corresponding explanations. Otherwise, after chunking, device attributes and descriptive content cannot be linked. A single document may include parameters for multiple device models. Chunking must divide boundaries by model or heading to avoid mixing information from different devices. Documents contain large numbers of technical values with units. Chunking must retain the contextual binding of values and units to prevent loss of association after splitting. Some documents are compressed packages of test report collections. Independent boundaries of individual reports must be identified before parsing.
How to Configure Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
maxChunkSize | 800–1200 characters | Aligns with the average length of parameter descriptions and technical content in computer equipment documents, to avoid splitting cross-parameter paragraphs |
chunkOverlap | 100–150 characters | Retains contextual association between adjacent chunks, to avoid splitting technical values with units |
PARSE_FILE_MAX_SIZE | 200 MB | Aligns with the common size of single hardware manuals and test report collections, to avoid parsing timeouts |
PARSE_OCR_ENABLE | Enabled | Supports documents with hardware appearance parameters and test data screenshots, to extract technical values from images |
retainMetadata | Enabled | Retains document metadata such as model numbers and release dates, to facilitate subsequent filtering by device dimension |
splitByHeading | Enabled | Divides chunk boundaries using second-level headings in documents, to avoid splitting parameter groups for the same device model |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: After upgrading the version, an error "Cannot redefine property: toString" appears in logs when parsing device parameter CSV files. Cause: The new version of the document parsing module has compatibility conflicts with the custom field processing logic of older versions, and object property bindings are not properly reset.
- Symptom: The number of chunks after parsing a single hardware manual exceeds 3000, and knowledge base indexing cannot be completed. Cause: The
maxChunkSizeparameter is not configured, and chunk boundaries are not divided by document headings, leading to excessive splitting of long text. - Symptom: In parsed chunks, technical values are separated from their corresponding units and model information. Cause: Contextual overlap is not retained during chunking, and splitting is not performed along the row boundaries of structured parameter tables, leading to disconnection of associated information.
How to Confirm Configurations Are Correct
- Upload a typical device parameter document, view the parsed chunk list, and confirm that each chunk contains complete parameter and descriptive content with no disconnections.
- Check parsing logs to confirm there are no error records for file size exceeding limits or parsing timeouts, matching the configured
PARSE_FILE_MAX_SIZEandPARSE_FILE_TIMEOUT_SECONDSparameters. - Randomly extract chunk content, verify that technical values, their corresponding units, and model information are fully bound with no losses.
- Test batch upload of multiple device documents of different models, confirm that the number of chunks meets expectations, and there are no abnormal errors.
