What Data for This Category Looks Like
Investment research data for the optical and optoelectronics field comes from multiple sources. These include monthly supply and demand reports from industry associations, quarterly financial reports of listed companies, technical documents from patent databases, laboratory test parameter reports, and transaction data from upstream and downstream industrial chains. Data update cycles vary significantly. Financial reports are updated quarterly, industry reports are released monthly, and patent and test data are synchronized in real time. Document structures fall into three categories: structured parameter tables, long-form technical analysis, and industrial chain maps. Core fields include product model, performance parameters, publishing entity, and release date. Most parameter units use professional metrology standards such as cd/m², ppi, and nanometers.
What Constraints Do These Characteristics Impose on the "Citation Source and Traceability" Link
Multi-source and heterogeneous data sources require traceability systems to support metadata extraction for different document types. This prevents traceability mismatches across data sources. Mixed structures of structured parameter tables and long-form text require traceability anchors to accurately match specific segments where parameters are located. Broadly associating with entire documents cannot meet the precision requirements of investment research. Professional parameter unit labeling requires traceability information to include unit fields. Without this, investment research conclusions cannot be verified for accuracy. Data sources with different update frequencies require regular synchronization of traceability metadata. This prevents traceability information from outdated documents from being disconnected from current data.
Configuration Settings
This configuration applies to FastGPT 4.8.10 and later versions.
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
Recall Count | Top 8-12 results | Optical and optoelectronics investment research data mostly consists of specialized subdivision parameters. Too many recalled results will introduce redundant information, while too few will fail to cover core reference documents |
Similarity Threshold | 0.75-0.85 | The field is dense with professional terminology. A threshold that is too low will introduce irrelevant industry reports, while a threshold that is too high will miss precise technical parameter documents |
Citation Source Display Toggle | Enabled | Investment research scenarios require clear reference basis for each conclusion to ensure information traceability |
Chunk Length | 600-1000 characters | Optical and optoelectronics technical documents often contain consecutive paragraphs with associated parameters. Chunks that are too short will break the logical connections between parameters |
Metadata Extraction Rules | Extract document title, release date, enterprise name, parameter unit | Investment research reports require clear source entities and professional metrology standards to ensure complete traceability information |
Traceability Anchor Matching Mode | Exact segment matching | Traceability of professional parameters requires locating specific paragraphs. Fuzzy matching will lead to traceability mismatches |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, 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
- Citation sources are displayed in the debug interface, but citation fields are empty after official release. This occurs because the
Citation Source Display Togglewas only enabled in debug mode, and the function was not enabled in the global release configuration. - The text content extraction component cannot extract document information referenced by the knowledge base. This occurs because the
Metadata Extraction Ruleswere not configured to include reference anchor fields, so the component cannot identify traceability-associated document metadata. - The published knowledge base page does not display unit information corresponding to parameters. This occurs because the
Metadata Extraction Ruleswere not configured to extract parameter unit fields, resulting in missing professional dimensions in traceability information.
How to Verify Successful Configuration
- Initiate a query containing optical and optoelectronics professional parameters, and check whether traceability information such as document title, release date, and parameter unit is displayed below the reply.
- Enter the knowledge base management page, and check whether the
Citation Source Display Toggleis enabled. - Call the text content extraction component, input conversation context that references the knowledge base, and confirm that the component output includes metadata of traceable documents.
- Publish a test version of the knowledge base page, and check whether each reply’s corresponding citation source is fully displayed on the page.
