What Data for This Category Looks Like
Financial report data for the chemical raw materials category comes from quarterly reports, annual reports, and temporary announcements disclosed by domestic and overseas listed entities. Updates follow a fixed quarterly and annual cadence, supplemented by temporary disclosures triggered by sudden industry policy changes or capacity shifts. Document structures include core operating data chapters, with fields covering capacity, output, average raw material procurement price, gross profit per unit product, inventory turnover days, and other metrics for various basic chemical raw materials. Common units include ten thousand tons, tons, yuan per ton, and 100 million yuan.
What Constraints These Characteristics Impose on Vector Models and Indexing
The multi-frequency update pattern of chemical raw material financial reports requires indexes to support incremental synchronization based on announcement time and reporting period. This avoids excessive time spent on full reindexing. The mixed structure of structured numerical data and unstructured analysis text requires converting values and units into standardized text fragments before embedding. This prevents loss of data dimensions in vector representations. The dense professional terminology content requires selecting vector models fine-tuned for the basic chemical industry. This improves embedding accuracy for technical terms. The timeliness requirements for temporary announcements require adding timestamp weights to indexes. This prioritizes recalling announcement data from the last three months.
How to Configure Settings
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
segment_length | 800–1200 characters | Matches the text length of professional term combinations and operating data in chemical raw material financial reports, avoids splitting context |
chunk_overlap | 100–150 characters | Covers cross-segment industry term associations, ensures contextual coherence for terms such as "polyvinyl chloride" and "MDI" |
embedding_model | Open-source vector model fine-tuned for the basic chemical industry | Adapts to embedding accuracy for industry-specific terms, improves recall matching precision |
index_refresh_interval | 86400 seconds | Matches the fixed quarterly financial report update cycle, supports daily incremental synchronization of temporary announcement data |
recall_top_k | Top 8–10 results | Balances recall accuracy and total context length, avoids interference from excessive low-relevance historical data in analysis |
similarity_threshold | 0.72–0.78 | Filters general industry text unrelated to chemical raw material operating topics, retains highly relevant data fragments |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material form, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: When starting vector index configuration, no optional options appear in the index model dropdown menu, and subsequent setup cannot be completed. Cause: The deployment address and authentication parameters of the vector model are not filled correctly, so the system cannot identify available models.
- Phenomenon: After importing multiple financial report documents, the recalled fragments contain a large amount of general text unrelated to chemical raw material operations, leading to large deviations in analysis results. Cause: A reasonable similarity threshold is not set, or a vector model adapted to the basic chemical industry is not selected, resulting in insufficient embedding accuracy for professional terms.
- Phenomenon: After updating quarterly financial reports, historical data from previous years still occupies the top positions in recall results, leading to insufficient timeliness. Cause: Timestamp weights are not enabled in the index configuration, or documents are not classified and indexed by reporting period, resulting in failure of the data sorting logic.
How to Confirm Proper Configuration
- Upload a single chemical raw material financial report document, check the parsed segmented fragments, confirm that professional terms are not split, and that segment length matches the preset configuration.
- Enter the index management page, check the index update log, confirm that incremental update tasks are triggered regularly according to the preset update interval.
- Initiate a financial report analysis query, verify that the number of recall results matches the preset recall count, and that the results include operating data fields for the target chemical raw materials.
- Check the vector model call log, confirm that each embedding request uses the configured domain-adapted model, and does not fall back to a general-purpose model.
