What the data for this category looks like
Data sources for semiconductor research reports include third-party industry research institutions, public listed company financial reports, and industry exhibition disclosures. Update schedules adjust dynamically with industry events. Regular reports are released quarterly, and temporary reports are added for sudden technology iterations or capacity changes. Documents mostly use a long text-image mixed structure, including core data tables, industry chain flowcharts, and excerpts of manufacturer capacity plans. Fields include professional parameters such as process node, shipment volume, and gross margin. Units use industry-standard values such as nanometers, ten thousand wafers, and percentages.
Constraints imposed on deployment and upgrade by these characteristics
High proportions of long documents with embedded tables and images extend per-file parsing time. Parsing timeout thresholds must be adjusted during deployment. Volatile update schedules mean regular scheduled incremental updates cannot adapt to sudden temporary reports. An event-triggered incremental synchronization mechanism must be configured. Professional parameter units and field naming follow industry-specific rules. Vector models must adapt to professional semantics, and field validation rules must be configured to filter invalid data. Large differences exist across multi-source data formats. Compatibility with layout structures of reports from different institutions must be maintained during upgrades to avoid parsing errors.
Configuration recommendations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Semiconductor research reports are mostly long documents with embedded tables and images. Parsing takes longer under standard conditions, and 600 seconds covers most single-file parsing requirements |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Some semiconductor research reports include complete financial report appendices and high-definition industry chain diagrams. Single-file size can reach hundreds of MB, and this value accommodates most compliant files |
maxContext | 8000–12000 characters | Core argumentative paragraphs of research reports are mostly long text. Adapting to this window preserves complete professional analysis logic |
Recall Count | Top 8–12 results | Semiconductor research reports cover many professional dimensions. A sufficient number of relevant segments must be recalled to cover information such as capacity, process, and market |
Similarity Threshold | 0.72–0.85 | Professional terminology has high semantic differentiation. This range filters general industry documents and retains accurate semiconductor-specific content |
RE_RANK_TOP_N | Top 3–5 results | The re-ranking phase must screen the most relevant segments to avoid excessive redundant content interfering with question answering logic |
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 specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three common errors
- Phenomenon: Calling the embedding interface returns a 503 error, and the interface displays "Vector service unavailable". Cause: The bge-m3 access endpoint of GPUStack is not configured correctly, or model loading fails due to insufficient allocated video memory.
- Phenomenon: Dependency conflict errors occur when deploying marker locally, or crashes occur during parsing due to insufficient video memory. Cause: The marker docker image was not built according to official guidelines, or sufficient graphics card video memory was not reserved for processing high-definition images in research reports.
- Phenomenon: Search results are not updated synchronously after knowledge base image updates. Cause: A FastGPT version that supports image index update is not used, or incremental reindex operation is not manually triggered.
How to confirm proper configuration
- Upload a test semiconductor research report, check the parsing log, confirm that parsing time does not exceed the configured
PARSE_FILE_TIMEOUT_SECONDSthreshold, and table content is fully extracted. - Initiate a vector recall test, verify that the similarity of returned results falls within the preset range, and no large number of irrelevant general industry documents are mixed in.
- Trigger an incremental update operation, check the knowledge base index progress, confirm that newly added or modified research report content has been synchronized to the vector database.
- Call the embedding interface, return normal vector data, no connection timeout or permission errors.
