Model Access and Configuration for Chemical Raw Material Investment Research Knowledge Base Construction

Chemical raw material data sources include industry association public monitoring data, monthly production and sales announcements from manufacturers

What data for this category looks like

Chemical raw material data sources include industry association public monitoring data, monthly production and sales announcements from manufacturers, customs import and export trade statistics documents, Material Safety Data Sheets (MSDS), and upstream and downstream industry chain related documents. Update frequencies cover weekly, monthly, and quarterly. Document formats include structured spreadsheet documents, long-form industry analysis PDFs, and standardized parameter manuals. Fields include product CAS number, production capacity, monthly shipment volume, ex-factory unit price, warehousing and logistics parameters, with units such as tons, yuan per ton, cubic meters, and others.

Chemical raw material data includes both structured parameter documents and long-form text analysis reports. The parsing logic for different document formats varies, so targeted parsing trigger rules must be configured. The update cadence of weekly ex-factory price data and quarterly industry capacity reports differs significantly, so different scheduled synchronization intervals and incremental update verification logic must be matched. Unique identifier fields such as product CAS number and capacity values require precise matching rules for entity extraction to avoid cross-category entity confusion. Some documents contain non-standard unit expressions, so pre-processing rules for unit standardization conversion must be configured.

How to set configurations

Configuration ItemRecommended SettingRationale
PARSE_TABLE_ENABLEEnabledMost chemical raw material documents contain structured capacity and price tables, enabling this option allows extraction of structured fields
UPLOAD_FILE_MAX_SIZE2000 MBSome industry report PDFs have large file sizes, this setting accommodates long document upload requirements
maxContext8000–12000 charactersLong-form industry reports require sufficient context to associate upstream and downstream industry chain data
RECALL_TOP_KTop 6–8 entriesChemical raw material data has many field dimensions, sufficient associated entries must be recalled to avoid missing information
SYNC_INTERVAL168 hours (weekly data sources) or 720 hours (quarterly data sources)Matches the official update frequency of different data sources to reduce unnecessary synchronization
ONE_API_MODEL_TOKEN_LENGTH4096Accommodates scenarios with many chemical raw material parameter fields, avoids call failures caused by insufficient token length

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by document format, data volume, and business rules. Specific issues require targeted analysis, and it is recommended to test on your own samples before finalizing settings.

Three common configuration mistakes

  • Phenomenon: After upgrading the version, the saved qwenplus model configuration automatically switches to gpt-4o during chat. Cause: The global model binding rules were not re-verified after the version upgrade, and the system default model overrode the custom application's model configuration.
  • Phenomenon: When using marker to process chemical raw material PDF documents, processing time exceeds a reasonable range. Cause: Redundant image parsing configuration was not disabled. Chemical raw material MSDS documents contain a large number of unnecessary safety identification images, which occupy significant processing resources.
  • Phenomenon: Adding a token in oneapi returns Error 1406 (22001): Data too long for column 'models'. Cause: The input length of the model call list was not limited. The chemical raw material category requires association with multiple product parameter models, resulting in an overly long model name list that exceeds the database field limit.

How to confirm the configuration is complete

  • Navigate to the application configuration page, verify that the Model Binding item matches the preset configuration, and confirm it is not overwritten by the global default configuration.
  • Upload a single structured chemical raw material parameter document, check whether the capacity and price fields in the parsing results are fully extracted, to verify that the PARSE_TABLE_ENABLE configuration takes effect.
  • Trigger a scheduled synchronization task, check that the number of updated documents in the synchronization log matches the update records of the corresponding data source.
  • Initiate a single model call test, verify that the model name in the call log matches the configured model parameters.
