What Data for This Category Looks Like
Financial report data for the chemical fiber category comes from public periodic reports of listed companies disclosed by domestic and overseas stock exchanges, plus official industry monitoring data published by relevant chemical fiber industry bodies. Data is updated on a fixed schedule: quarterly operating data is released quarterly, half-year reports are released semi-annually, and annual reports are released annually. All disclosures occur within two months after the end of the reporting period.
Documents are split into three modules: financial statements, discussion and analysis of operating conditions, and core business data. The core business data module includes production and sales figures for segmented products, raw material consumption, capacity utilization, and related metrics.
Available fields include polyester filament sales (tons), polyester chip production costs (yuan/ton), accounts receivable turnover days (days), polymerization plant utilization rate, and other industry-specific metrics. Most units use standard weight, currency, or time units. No percentage-based proportional statements are included.
Constraints on Model Access and Configuration
Chemical fiber financial report data has fixed update cycles but lengthy individual documents. The core business data module in particular occupies significant model context space, so context window parameters optimized for long text must be configured.
Most fields are industry-specific industrial metrics, so the model must support recognition of segmented terminology. During model access, a domain-adapted model must be specified, or terminology recognition weights must be configured. Additionally, field naming may vary across different data sources. Unified field mapping rules must be configured to prevent parsed data formats from becoming inconsistent.
Some data units may be inconsistent across documents, so automatic unit conversion parameters must be configured to ensure data consistency.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Adapts to the average length of the core business module of chemical fiber financial reports, avoids truncation of core data such as production capacity and costs |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Covers the parsing time required for chemical fiber financial reports containing multiple segments of detailed business data, prevents task interruption mid-process |
chunkSize | 1000–1500 characters | Balances content coherence and retrieval accuracy for chemical fiber financial reports, avoids destroying metric correlation by using overly short segments |
fieldMappingRule | Map according to chemical fiber industry standard terminology | Unifies naming formats for exclusive fields such as "polymerization capacity" and "PTA purchase price", facilitating model recognition |
similarityThreshold | 0.75–0.85 | Filters low-match irrelevant content, adapts to the semantically similar characteristics of chemical fiber industry terminology |
retrieveTopK | Top 6 entries | Covers the distribution concentration of core business data in chemical fiber financial reports, improves retrieval efficiency |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Phenomenon: Model calls return a 422 status code, with a prompt message indicating token length does not meet requirements. Cause: The
maxContextparameter is not configured for long text fragments of chemical fiber financial reports, causing incoming document content to exceed the model's supported token limit. - Phenomenon: Parsing tasks fail after uploading financial report documents, with a timeout error displayed in the interface. Cause:
PARSE_FILE_TIMEOUT_SECONDSis set to a value lower than the actual required parsing time, without accounting for the parsing time of chemical fiber financial reports containing multiple segments of detailed business data. - Phenomenon: A large amount of general financial report content is mixed into retrieval results, and exclusive metrics for the chemical fiber category are not hit. Cause:
fieldMappingRuleis not configured, orsimilarityThresholdis set too low, causing the model to recall irrelevant non-chemical fiber industry data.
How to Confirm Proper Configuration
- Upload a local financial report document of a chemical fiber listed company, review the parsed field list to confirm that core industrial metrics have been correctly identified and mapped to a unified format.
- Initiate an analysis request for chemical fiber financial reports, check whether the returned results cover core business data within the configured number of retrieved entries, adjust
similarityThresholdto filter irrelevant content. - Run batch parsing tasks, confirm that all tasks complete within the time period set by
PARSE_FILE_TIMEOUT_SECONDS, with no timeout errors. - View model call logs, confirm that the incoming context length does not exceed the configured range of
maxContext, with no token limit related errors.
