What This Category of Data Looks Like
Carbon steel financial report data primarily originates from periodic reports and temporary announcements disclosed by domestic and overseas stock exchanges, as well as monthly operating data released by industry associations. Updates follow quarterly and annual core cycles, with temporary performance forecasts or adjustment announcements released synchronously. Document structures include structured tables (such as output, revenue, and cost breakdowns) and unstructured analysis paragraphs (such as industry trend interpretations). Core fields include crude steel output, per-ton steel gross profit, raw material procurement costs, and others. Common units are ten thousand tons, yuan per ton, and hundred million yuan.
Constraints for Document Parsing and Chunking
Structured tables make up a large portion of carbon steel financial reports, and fields are tightly bound to their respective units. During parsing, it is necessary to accurately identify table boundaries and unit information to prevent splitting associated data across tables. The high update frequency requires support for batch and scheduled document synchronization. During chunking, chapter hierarchy must be preserved to avoid mixing data from financial reports of different cycles. Additionally, some financial report PDFs feature complex table layouts; conventional parsing often loses formatting and field associations, so targeted optimization of parsing logic is needed.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Segment Length | 800–1200 characters | Adapts to the average length of single-paragraph analysis content and table row groups in carbon steel financial reports, avoiding overly fragmented or overly long chunks |
Maximum Paragraph Depth | 3 | Matches the chapter nesting hierarchy of carbon steel financial reports (report chapter > sub-chapter > subsection) to preserve contextual association of content |
Enable Multi-Vector Support | Enabled | Generates multi-dimensional vector indexes for the large volume of structured table data in carbon steel financial reports, improving recall accuracy for table fields |
PDF Enhanced Parsing | Enabled | Preserves table structures, unit information, and embedded fields in officially disclosed PDF documents, avoiding data loss after parsing |
Chunk Overlap Rate | 10–15% | Reduces content splitting across chapters and tables, ensuring contextual integrity within chunks |
API Call Timeout | 600 seconds | Adapts to the parsing time of large carbon steel financial reports, avoiding task interruption due to API call timeout |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on local samples before finalizing settings.
Three Common Misconfigurations
- Empty table data recall after configuration. Phenomenon: Knowledge base searches cannot retrieve table fields such as crude steel output and per-ton steel gross profit from financial reports. Cause:
Enable Multi-Vector Supportis not enabled, so only plain text content is chunked, and no vector indexes are extracted for structured tables. - Loss of units and formatting after PDF parsing. Phenomenon: Units such as "yuan per ton" and "ten thousand tons" are missing from parsed text, and table rows are disorganized. Cause:
PDF Enhanced Parsingis not enabled, so default parsing does not retain PDF-embedded table structures and unit fields. - Timeout after API-triggered chunking. Phenomenon: Chunk API calls return 504 status codes or timeout errors. Cause:
API Call Timeoutis not adjusted to 600 seconds, so parsing time for large carbon steel financial reports exceeds the default API timeout threshold.
How to Confirm Proper Configuration
- Upload a standard carbon steel financial report PDF, then review the parsed text to confirm that table units and field names are fully retained, with no garbled characters or formatting errors.
- Navigate to the settings page of the corresponding knowledge base, verify that the
Enable Multi-Vector Supportswitch is enabled, and thatSegment Lengthis set within the 800–1200 character range. - Call the chunking API interface with a test document, then check if the returned chunk results include independent fragments of structured tables, and that content is not split across chapters.
- Search for preset carbon steel financial report keywords in the knowledge base, confirm that table-related fields are accurately retrieved with no omissions or incorrect matches.
