What the data for this category looks like
Optical module financing daily report data is sourced from public financing disclosure announcements and daily summaries from industry news platforms, with a daily update frequency. Each daily report contains one or more financing event entries. Each entry includes fields such as the name of the relevant optical module entity, financing amount (unit: ten thousand yuan or hundred million yuan), financing round, investor list, disclosure date, optical module product type, and associated transaction amount. Most documents are structured tables or text files with clear field labels.
What constraints do these characteristics impose on knowledge base retrieval and recall
The daily update requirement means the knowledge base must support incremental synchronization. The recall process must prioritize newly disclosed events to avoid interference from outdated information. Fields include detailed business attributes such as optical module product type and financing amount, with inconsistent units across entries. This requires the retrieval process to perform synonym expansion for product types, normalize amount units, and support field filtering. Additionally, single event descriptions are lengthy. When splitting text into chunks, balance context completeness and retrieval accuracy, and avoid breaking semantic associations between business fields.
How to configure settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_CHUNK_SIZE | 800–1200 characters | Single event descriptions in optical module financing daily reports are lengthy. Too large a chunk size will lose context associations, while too small a size will damage the integrity of business fields |
RECALL_TOP_N | Top 8–12 entries | The number of daily financing events is limited. Too many recalled results will cause redundancy, while too few will miss key business events |
SIMILARITY_THRESHOLD | 0.72–0.85 | Balances accurate matching of business keywords such as 800G optical module and Series C financing, and recall coverage. It avoids mistakenly recalling financing events from non-optical module fields |
INCREMENTAL_SYNC_INTERVAL | 60 minutes | Matches the daily update rhythm of daily reports, ensuring newly disclosed financing events are synced to the knowledge base in a timely manner |
FIELD_FILTER_ENABLE | Enabled | Supports filtering recall results by fields such as optical module product type and financing round, to align with business segmentation needs |
RERANK_TOP_N | Top 3–5 entries | Focuses on the most relevant and latest financing events, improving the practicality of retrieval results |
The parameter values provided on this page are common recommended 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
- Phenomenon: Unable to recall target entries via optical module model numbers in query terms. The recall results returned by the console do not include title matching items. Cause: Retrieval weight configuration for title fields is not enabled, or the word segmentation process does not retain the complete semantics of the title.
- Phenomenon: Model generation response time exceeds 25 seconds after knowledge base retrieval. Logs show a
context window overflowerror. Cause: The number of recalled entries is set too high, causing the input context to exceed the model's context window limit, and the re-ranking process is not configured to compress valid content. - Phenomenon: Retrieval results include financing events from non-optical module categories, or financing amount units are mixed. Cause: The field filter switch is not enabled, or the amount unit of ingested documents is not normalized, leading to insufficient retrieval accuracy.
How to verify correct configuration
- Enter a query containing optical module model numbers and financing rounds, run a single retrieval test, and check the field integrity and business relevance of the recall results
- View the knowledge base sync logs to confirm that daily incremental sync tasks trigger on schedule, with no failed error records
- Modify parameters such as similarity threshold and number of recalled entries, verify that configuration changes take effect in real time
- Check the field filter configuration to confirm that only financing events related to optical modules are included in the recall range
