Data Characteristics of This Category
Commercial property financial report data primarily originates from property operation management systems, rent collection ledgers, business type filing reports, and annual audit reports. Update cycles are divided into three categories: monthly operation data, quarterly business briefings, and annual official financial reports. Annual official financial reports must be filed with the local competent authority within four months after the end of the fiscal year. Documents are centered on structured tables, with fields including rentable area, total receivable rent, actual collected amount, business type proportion values, and other metrics. Some documents include unstructured paragraphs such as operation status descriptions and tenant structure analysis. Field units include square meters, yuan, and other measurement standards.
Constraints Imposed on Vector Models and Indexing
The high structured proportion, large number of fields, and clear measurement standards of commercial property financial reports require the indexing process to retain row-column association information, preventing damage to data logic during splitting. Data sources with multiple update cycles create high demand for batch indexing. The system must support time-based targeted updates to avoid full reindexing. The length of single financial report documents varies widely, from dozens of pages of quarterly briefings to hundreds of pages of annual audit reports. Indexing chunking strategies must adapt to the mixed structure of long text descriptions and short tables. Additionally, avoid redundant indexing caused by duplicate fields or table splitting. Set the indexing construction timeout threshold appropriately to match the timeliness requirements from filing deadlines.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_TABLE_MODE | Retain row-column association | Commercial property financial reports contain a large number of structured tables. Retaining row-column association avoids breaking data logic during splitting |
CHUNK_SIZE | 800–1200 characters | Adapts to the mixed structure of long text descriptions and short tables in financial reports, balancing context association and chunk granularity |
SIMILARITY_THRESHOLD | 0.72–0.85 | Financial reports have many fields and high precision requirements. This interval filters low-relevance recall results |
RECALL_TOP_K | Top 6–8 results | Covers the query requirements of multiple financial report fields, avoiding redundancy caused by too many recall results |
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | Single annual financial report documents have a large length, reserving sufficient time for parsing and indexing |
ENABLE_TABLE_VECTOR | Enabled | Structured tables are core data for financial reports. Enabling this improves field-level recall accuracy |
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, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: After uploading a single financial report document, the interface initially displays 8 segments, then changes to 13 segments after a period of time, with duplicate segmentation. Cause: The
PARSE_TABLE_MODEretain row-column association setting is not enabled, causing cell text within tables to be repeatedly split into different segments. - Phenomenon: After upgrading from version 4.9.0 to 4.9.3, previously queryable financial report content can no longer be recalled, returning empty results. Cause: The new version adjusted the default
CHUNK_SIZEparameter. The chunk format of old documents does not match the new parameter, and content cannot be correctly recalled without reindexing. - Phenomenon: Batch retraining of the vector model cannot be triggered, and only single-file parameter adjustment followed by separate upload is supported. Cause: The
AUTO_REINDEX_BATCHparameter is not configured, and the batch indexing scheduling function is not enabled, making unified retraining of multiple documents impossible.
How to Confirm Correct Configuration
- Upload a single quarterly financial report document, view the parsed segment details, and confirm that row-column association information for tables is not damaged.
- Enter query terms that include exclusive fields such as "rentable area" and "total receivable rent", and check whether the relevance of recall results meets business expectations.
- Check the indexing task run logs, and confirm that no parsing timeout or duplicate segmentation error messages appear.
- Trigger a batch indexing task, and verify whether the function of time-based targeted update of financial reports for a specified time period works properly.
