What the Data for This Category Looks Like
Data for cultural and entertainment product research reports comes primarily from public reports released by industry consulting institutions, public financial reports of leading brands, offline retail inventory and sales data, and e-commerce platform sales monitoring data. The update cycle is mostly monthly; ad-hoc updates are made for research reports tied to industry hot events such as new product launches or policy adjustments.
Document structure includes fields such as report title, issuing institution, release date, core category revenue data, segmented SKU sales volume, channel share, trend analysis, and more. Most fields involve entity names, numerical data, and qualitative analysis content, with units including RMB yuan, units, and others.
What Constraints Do These Characteristics Impose on the "Document Parsing and Chunking" Link
The multi-source data characteristics of cultural and entertainment product research reports require the parsing process to adapt to structured tables, unstructured analysis paragraphs, and semi-structured monitoring data simultaneously.
The relatively high update frequency requires that chunk size not be too large, to avoid excessive synchronization costs during subsequent incremental updates.
The large number of entity names and cross-paragraph associated analysis content in reports requires that chunking retain contextual semantics, to avoid splitting core retrieval entities from their associated information.
The cross-page layout of some reports requires chunking by theme instead of by page number, to ensure complete thematic content per chunk.
How to Configure the Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
segment_length | 800–1200 characters | Cultural and entertainment product research reports include entity names, revenue data, and analysis paragraphs. This range retains core semantics while avoiding excessively long chunks that impair retrieval performance. |
chunk_overlap_rate | 15%–20% | Research reports contain a large amount of cross-paragraph associated information. Setting overlap reduces contextual breaks. |
enableTableParse | Enabled | Cultural and entertainment product research reports often include structured sales and revenue tables. Enabling this option retains row and column association information for tables. |
mineruApiKey | Enter a valid API key | For PDF-format research reports, enhanced parsing can extract annotation text next to charts and embedded table data. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Large research report files take longer to parse. This duration prevents mid-parsing timeouts. |
splitBySemantic | Enabled | Some research reports use cross-page layout organized by theme. Semantic chunking retains complete thematic content per chunk. |
The parameter values provided on this page are general recommendations to serve as a starting point for configuration. 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 Misconfigurations
- After uploading an Excel-format cultural and entertainment product research report, only the first two columns of data are recognized as knowledge base content. This occurs when multi-column table parsing configuration is not enabled. The default logic only extracts the first two columns as associated content for question and answer pairs.
- When using the PDF enhanced parsing function, the returned parsing results lack annotation text next to charts. This happens when the
mineruApiKeyparameter is not configured or the key is invalid, causing the enhanced parsing function to not trigger properly. - When retrieving core content from cultural and entertainment product research reports, semantically broken retrieval results appear. This is caused by segment length being too short or chunk overlap rate being insufficient, leading to core entities and their associated analysis content being split into different chunks.
How to Verify Correct Configuration
- Upload a single small PDF-format cultural and entertainment product research report, view the parsed chunk list, and confirm that table content is fully extracted and not split.
- Enter the parsing settings module of the knowledge base configuration page, check the entry status of
mineruApiKey, and confirm that the key is valid and has not been tampered with. - Upload an Excel research report file containing multiple columns of data, view the parsed field list, and confirm that all column data is recognized and imported into the knowledge base.
- Test retrieval for a cultural and entertainment product brand name, view the returned chunk content, and confirm that associated revenue data and analysis paragraphs are fully contained in the same chunk or adjacent chunks.
