What the data for this category looks like
Cultural and entertainment products investment research data mainly comes from annual reports released by industry associations, public financial reports and product manuals from manufacturers, sales monitoring data from e-commerce platforms, IP licensing agreements, and offline exhibition survey records. Updates are concentrated around new product launches and financial report disclosure seasons, with scattered updates accompanying industry dynamics and channel sales data on an ongoing basis. Common document formats include multi-column structured Excel sales ledgers, industry whitepaper PDFs with nested tables, Word R&D documents with parameter lists, and CSV supply chain data files. Core fields include SKU codes, product categories, licensing fees, shipment volumes, material parameters, and more. Units include pieces, ten thousand yuan, meters, grams, and others.
What constraints do these characteristics impose on the document parsing and chunking link
Multi-column structured Excel sales ledgers cause the default chunking logic to fail to identify business units. This easily splits the same product data across columns into different segments. Industry documents with nested tables lose key investment research information such as SKU comparisons and channel proportions if structure is not retained during parsing. Documents with different update frequencies require adapted parsing modes; chunking logic differs between static industry standard documents and dynamic sales data. Forcing character-based splitting of proprietary cultural and entertainment product terms such as IP names, SKU codes, and licensing clauses damages semantic integrity.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_EXCEL_SHEET_MODE | Split by row | Cultural and entertainment products investment research documents are mostly SKU ledgers and sales data. Each row corresponds to a single product or transaction record. Splitting by row preserves business integrity |
MAX_PARSE_CHUNK_SIZE | 800–1200 characters | Cultural and entertainment products documents contain product parameters and industry terminology. Overly long chunks cause semantic fragmentation. Overly short chunks lose contextual association |
PARSE_KEEP_TABLE_STRUCTURE | Enabled | Cultural and entertainment products investment research documents often include nested tables and SKU comparison tables. Retaining structure prevents post-parsing information chaos |
UPLOAD_FILE_MAX_SIZE | 500 MB | Large exhibition materials and annual supply chain reports have large individual file sizes. This setting adapts to large file upload requirements |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing multi-page PDFs and nested tables takes significant time. This setting avoids timeout interruptions |
AUTO_CHUNK_SPLITTER | Split by semantic unit | R&D documents and licensing contracts for cultural and entertainment products have clear semantic units. Splitting by semantics better fits investment research needs than fixed character count splitting |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: After uploading an XLSX format document, the content returned by the knowledge base only contains headers or empty fields. Cause: The Excel structured parsing mode is not configured. The default behavior merges the entire table into a single text block, failing to retain column-level business information.
- Phenomenon: After uploading a multi-column SKU sales ledger, the automatic chunking result is chaotic. Cross-column data of the same product is split into different segments. Cause: A fixed character length chunking logic is used, failing to adapt to the business unit characteristics divided by rows in cultural and entertainment products documents.
- Phenomenon: After uploading a single attachment, the parsing result includes content from previously uploaded documents. Cause: The global incremental parsing switch is not turned off. The system defaults to merging the current and previously uploaded documents of the same type for parsing.
How to confirm the configuration is correct
- Upload a test multi-column SKU ledger XLSX document. Check the parsed text blocks to confirm each row of content is used as an independent segment.
- Upload an industry whitepaper PDF containing nested tables. Check that the parsing result retains the table's row and column structure with no content loss.
- After uploading a single test document, check the parsing log to confirm only the currently uploaded file is included in the parsing scope, with no historical document content mixed in.
- Upload a product packaging image. Check that the content returned by the knowledge base includes the text information in the image, confirming the OCR process is triggered normally.
