What this category of data looks like
Computer equipment financing daily report data comes primarily from project ledgers of financial leasing institutions, public disclosure information for government computer equipment procurement, and shipment filing data from equipment manufacturers. Updates occur daily, covering new computer equipment financing projects from the previous calendar day. Most documents use structured tables. Core fields include financing subject, equipment model, single device financing amount, total financing scale, financing institution, loan date, and repayment period. Corresponding units are name, model, CNY, CNY, institution name, YYYY-MM-DD formatted date, and month/year.
What constraints do these characteristics impose on knowledge base retrieval and recall
This category has many structured fields, and some fields share names but have different meanings. For example, single device financing amount and total financing scale. Retrieval operations require precise matching of field identifiers to avoid confusing results. Updates occur daily, so the retrieval pipeline must support incremental index updates to reduce resource consumption from full index rebuilding. Equipment models have hierarchical classifications, such as laptops, servers, and peripherals. The same model may link to multiple financing subjects. Recall operations must prioritize matching combined conditions of equipment model and financing subject. The loan date field requires the retrieval pipeline to support time range filtering, to screen financing projects within a specified period.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | The fields in computer equipment financing daily reports are mostly short text, amounts, and dates. This segment length preserves field integrity and avoids truncating critical information |
recallTopK | Top 10 entries | New financing entries per day typically fall in the hundreds range. Recalling the top 10 entries covers core financing projects and avoids redundant results |
similarityThreshold | 0.75–0.85 | Equipment model and financing subject are strongly matching fields. This threshold filters low-correlation non-target financing entries |
rerankTopN | Top 5 entries | High-precision, highly matched results must be retained for subsequent context supplementation in knowledge base question answering |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Structured table parsing requires reading multiple fields. This duration prevents timeout for large daily report file parsing |
enableIncrementalIndex | Enabled | Adapts to the daily incremental update rhythm, reducing server resource usage |
The parameter values provided on this page are common recommended starting points 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 mistakes
- Phenomenon: After restoring a project backup, no computer equipment financing daily report retrieval entries appear in the backend knowledge base. Cause: Only the project configuration file was restored, and vector database index data was not synchronized. Both the vector database directory and project configuration file must be backed up and restored together.
- Phenomenon: Knowledge base returned financing daily report content is truncated, and cannot fully display comparative data for single device financing amount and total financing scale. Cause: The
chunkSizeparameter value is too small, causing structured fields to be split and truncated, leading to loss of complete information. - Phenomenon: Retrieval results include financing projects unrelated to computer equipment. Cause: No equipment category filtering conditions were added to the retrieval configuration, and other category financing data was recalled only through keyword matching.
How to confirm correct configuration
- Upload a test computer equipment financing daily report file, view the parsed field list, and confirm all core fields are correctly extracted.
- Initiate a retrieval request, enter a specified equipment model and loan date range, and check whether the number of returned results and field content meet expectations.
- Adjust the similarity threshold and number of recalled entries, and verify whether the relevance and completeness of retrieval results meet business requirements.
- Execute an incremental update task, view the system index update log, and confirm that new daily report entries are correctly synchronized to the knowledge base.
