What data for this category looks like
Infrastructure construction financing daily report data mainly comes from public disclosure documents of housing and urban-rural development authorities, credit disclosure announcements of commercial banks, and statistical briefings of industry associations. It updates each business day, releasing the latest disclosed financing project information of the day. Single document structure includes fields such as project name, construction undertaking entity, financing amount, financing method, release date, and disclosure source link. Financing amount uses ten thousand yuan or hundred million yuan as its unit. Some projects attach local Development and Reform Commission approval document numbers.
What constraints these characteristics impose on citation sources and traceability
Official public sources for infrastructure construction financing daily reports usually have clear publishing entities and links. Traceability requires matching the official domain name of the disclosure source, to prevent unauthorized reposted content from being mixed in. Single documents contain multi-dimensional fields. Recall must accurately match core fields such as project name and financing amount. Otherwise, traceability results will have association errors. The daily business day update rhythm requires knowledge base synchronization frequency to align with the release cycle. Otherwise, traceability content will lag behind the latest disclosed information. Some projects include approval document numbers. Traceability must include this field in association verification, to ensure cited content fully corresponds to original disclosure.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
similarity_threshold | 0.65–0.75 | Core fields of infrastructure construction financing daily reports have high recognizability. This range filters low-association non-project content, while retaining association results for the same project across different disclosure sources |
retrieval_limit | Top 8 entries | Single daily report content is compact. 8 recall entries can cover multi-source disclosure information for a single project, avoiding redundancy |
rerank_top_n | Top 5 entries | Prioritize displaying officially released authoritative sources, which complies with compliance display requirements for infrastructure project financing information |
sync_interval | 24 hours | Aligns with the business day update rhythm. Daily synchronization ensures traceability content covers the latest disclosed projects of the day |
enable_source_verify | Enabled | Verifies official domain names, preventing unauthorized reposted content from being treated as valid traceability sources |
required_match_fields | Project name, financing amount | Ensures recalled content matches core information of the target project, avoiding traceability errors caused by field misalignment |
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 specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Phenomenon: After setting
similarity_thresholdto 1, a large number of non-target project citation content still appears. Reason: Project names in infrastructure construction financing daily reports use mixed abbreviations and full names. A strict 1 similarity threshold cannot match variant expressions, leading to some valid sources being filtered out or irrelevant content being mixed in. - Phenomenon: Citation sources include inaccessible links, or display a 404 status code. Reason: The
enable_source_verifyconfiguration is not enabled, and expired official disclosure links are not filtered. Some links from old disclosure content have been taken offline by the platform. - Phenomenon: Traceability results do not include content corresponding to the local Development and Reform Commission approval document number. Reason:
required_match_fieldsis not configured to include the approval document number. Only matching project name and amount leads to content with missing associated fields not being correctly recalled.
How to Verify Proper Configuration
- Access the knowledge base management interface, check the
sync_intervalconfiguration item, confirm the value matches the business day update rhythm. - Initiate a query containing a specific infrastructure project name and financing amount, review the citation list of returned results, confirm the proportion of links with official domain names meets expectations.
- Manually adjust the value of
similarity_threshold, compare the change in the number of associated results between the two queries, to verify that the configuration takes effect. - Copy an expired official link into the test knowledge base, initiate a relevant query, confirm the system does not include this expired link as a valid citation source.
