What the data for this category looks like
Packaging and printing research reports are sourced from light manufacturing industry databases, public materials released by industry associations in the packaging and printing segment, regular announcements of listed packaging and printing enterprises, and weekly price reports from raw and auxiliary material suppliers. Update frequency varies by data type: overall industry supply and demand research reports are updated quarterly, enterprise operation materials are released at disclosure deadlines, and raw and auxiliary material price data is updated weekly. Document structures typically include a table of contents, industry supply and demand analysis section, market size data for segmented categories such as corrugated packaging and flexible packaging, upstream and downstream industry chain linkage analysis, and policy interpretation and trend prediction sections. Fields include per-square-meter printing cost (unit: yuan/㎡), monthly production capacity scale (unit: 10,000 square meters), pulp purchase price (unit: yuan/ton), monthly equipment operating hours (unit: hours), and others.
What constraints these characteristics impose on the model access and configuration link
The multi-source and heterogeneous data characteristics of packaging and printing research reports require configuring parsing adapters compatible with different formats in the model access link, covering structured tables from industry databases, plain text from enterprise announcements, short text from weekly reports, and other types. Differences in update frequencies across different data require configuring layered timed synchronization trigger parameters to distinguish quarterly and weekly update cycles. Documents include long-text analysis and structured data for segmented categories, requiring configuration of precise recall parameters for table content. The diversity of field units requires configuring preprocessing rules for unit standardization to prevent models from confusing values with different measurement standards. Some individual research reports exceed 10,000 characters, requiring configuration of reasonable segment lengths to adapt to model context window limits.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | The typical length of individual packaging and printing research reports ranges from 5000 to 10000 characters, reserving sufficient space for processing recalled content and context interactions |
PARSE_TABLE_ENABLED | Enabled | Packaging and printing research reports contain a large number of structured tables for raw and auxiliary material prices and production capacity scales, requiring accurate extraction of numerical values |
DATA_SYNC_INTERVAL | Weekly synchronization | Covers weekly updated raw and auxiliary material price data, while also adapting to quarterly updated overall industry research reports |
RECALL_TOP_K | Top 8–12 entries | There are many segmented dimensions in packaging and printing research reports; an appropriate number of recalls can cover multi-dimensional retrieval needs such as category, region, and cost |
UNIT_STANDARDIZATION | Enabled | Research reports contain multiple measurement fields such as yuan/㎡, yuan/ton, and 10,000 square meters, requiring unified conversion to standard units |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing some large packaging and printing research report documents takes a long time, preventing parsing failures caused by timeouts |
The parameter values provided on this page are all common recommended starting points for determining configuration baselines. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to conduct tests on your own samples before finalizing settings.
Three common configuration mistakes
- Phenomenon: Raw and auxiliary material price fields are empty or have mixed numerical units in model-returned research report retrieval results. Cause: The
UNIT_STANDARDIZATIONconfiguration is not enabled, and multi-unit fields in research reports are not standardized, causing the model to fail to recognize values with unified measurement standards. - Phenomenon: After triggering data synchronization, parsing is not completed within the time set by the
PARSE_FILE_TIMEOUT_SECONDSconfiguration, and the task status shows a timeout error. Cause: The timeout parameter is not adjusted based on the actual parsing time of large packaging and printing research reports; the default timeout duration is too short to complete long document parsing. - Phenomenon: The results of model comparison experiments do not differ significantly, making it impossible to distinguish the retrieval effects of different models. Cause: A matching test dataset is not set for the segmented dimensions of packaging and printing research reports; using a general dataset fails to cover exclusive retrieval scenarios such as category and cost, leading to experimental results that lack specificity.
How to confirm successful configuration
- Upload a packaging and printing industry research report, view the parsed text and table content, and confirm that all structured fields are correctly extracted.
- Trigger a data synchronization task, check whether the updated data time after synchronization matches the configured
DATA_SYNC_INTERVAL. - Enter a retrieval question that includes segmented categories and costs, and check whether the number of recalled results falls within the configured recall range.
- Call the model interface to conduct a retrieval, and confirm that the measurement fields in the returned results are uniformly converted to standard units.
