What Data for This Category Looks Like
Chemical fiber industry investment research data comes from multiple sources: upstream raw material quotes of the petrochemical industry chain (such as PTA, ethylene glycol prices), monthly industry association reports, quarterly financial reports of listed textile enterprises, trading quotes from futures exchanges, and order data from downstream weaving enterprises.
Data update rhythms vary significantly. Raw material prices update daily. Industry dynamics update weekly. Financial reports update quarterly.
Document structures include three categories:
- Structured quotation tables, with fields such as fineness and degree of polymerization, using units of cN/dtex and 10,000 tons/year.
- Semi-structured research reports that embed capacity distribution maps and price trend charts.
- Unstructured industry analysis articles.
What Constraints These Characteristics Impose on Model Access and Configuration
The high proportion of structured data with diverse field units requires configuring a model access link that supports structured field parsing. This avoids unit recognition errors.
Large differences in data update rhythms require setting differentiated vector database synchronization frequencies for different data sources. This prevents recalling outdated data.
Documents contain a large number of embedded images. This requires additional configuration of a multimodal model access link to parse image content.
Individual research reports have large volume and long content. This requires adjusting the context window and file upload limits to fit business data characteristics.
How to Set the Configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | The core content of a single chemical fiber industry research report is mostly 5000-10000 characters, requiring coverage of complete data paragraphs |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Chemical fiber research reports often include high-definition capacity maps and futures K-line charts, resulting in large single-file sizes |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Parsing large structured quotation data sets takes a long time, to avoid mid-process interruptions |
Number of Recalled Entries | Top 8–12 entries | Chemical fiber investment research needs to consider multi-dimensional associated data including raw materials, downstream, and macroeconomics, requiring sufficient recalled entries |
Similarity Threshold | 0.72–0.80 | There are many chemical fiber sub-categories such as polyester, nylon, acrylic fiber, requiring filtering of low-correlation cross-category data |
PARSE_IMAGE_CONTENT | Enabled | Research reports contain embedded capacity distribution maps and price trend charts, requiring image content parsing to supplement vector features |
The parameter values provided on this page are common recommended starting points for determining configurations. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Only returning text content after calling the integrated
erwan2/DeepSeek-Janus-Pro-7B:latest. This occurs when the model's multimodal generation switch is not enabled, or the pre-parsing link for image input is not configured. - No image-associated features in the vector database after uploading a chemical fiber research report with embedded images. This occurs when the
PARSE_IMAGE_CONTENTconfiguration item is not enabled, or a model supporting multimodal embedding is not connected. - Returning a
504 Gateway Timeouterror when calling a locally deployed large model. This occurs when theLOCAL_MODEL_API_TIMEOUTparameter is not configured with a reasonable value adapted to local hardware, resulting in request timeout.
How to Confirm the Configuration Is Complete
- Upload a single chemical fiber research report of common industry length. Check that the parsed text segments match the configured
segment lengthparameter. - Enter a query containing the chemical fiber fineness unit dtex. Check that the returned results correctly recognize the unit and associate the corresponding structured data.
- Upload a chemical fiber capacity report containing high-definition images. Check that embedding features for the images are generated in the vector database.
- Test calling the configured model interface. Check that the returned status code is
200 OKand the content meets investment research requirements.
