What Data This Category Includes
Water utility financial report-related data comes from three main sources: annual, semi-annual, and quarterly reports publicly released by listed water utility enterprises, monthly industry operation reports published by municipal public utility regulatory agencies, and completion settlement archives for water utility projects.
Data update schedules follow regulatory requirements. Annual reports are updated once per year. Semi-annual reports are updated every six months. Monthly operation data is updated each month.
Document structures include standard financial statements and special water utility business notes. These notes contain dedicated fields such as average daily water supply volume, sewage treatment compliance rate, pipe network leakage rate, and unit water supply cost. Supported units include ten thousand cubic meters, yuan per ton, percentage, and others.
Constraints on Knowledge Base Retrieval and Recall
Dispersed data sources require independent recall trigger rules for each source. This prevents mixing monthly operation data and annual financial report content.
Water utility-specific fields require matching both field names and units during retrieval. Only fragments containing "average daily water supply volume (ten thousand cubic meters)" will be recalled, without generalized matching for "water supply volume".
Long document structures mean a single financial report note may hold multiple related data sets. When performing segmented recall, context between fields and their corresponding values must be retained. This avoids losing data association relationships after splitting.
Differences in update frequencies across data sources require configuring differentiated synchronization cycles for incremental knowledge base updates, grouped by data source type.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
segment_length | 800–1200 characters | Water utility financial report special notes contain multiple sets of related data. This range preserves context binding between fields and their corresponding values to avoid split breaks |
recall_count | Top 6–8 results | Water utility financial report-specific fields are concentrated. Too many recall results will introduce irrelevant standard financial content, while too few will fail to cover complete business scenarios |
similarity_threshold | 0.72–0.85 | Semantic matching accuracy requirements for dedicated business fields are high. This range filters low-correlation non-water utility content |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Single annual financial report files have large file sizes and long parsing times. This duration avoids mid-parsing timeout failures |
knowledge_base_grouping | Group by data source type | Distinguish between annual financial reports, monthly operation data, and project archives to enable precise recall of content within specified ranges |
answer_mode | Knowledge base content only, preset prompt for no results | Strictly limit responses to retrieved results, which complies with compliance requirements for water utility financial report analysis |
The parameter values provided on this page are standard recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis, and testing on samples specific to the deployment is recommended before finalizing settings.
Three Common Configuration Errors
- Symptom: Responses include standard financial explanatory content not uploaded to the knowledge base. Cause: The
answer_modeconfiguration was not set to knowledge base only mode, leading the large language model to use pre-trained knowledge. - Symptom: Retrieval results mix water utility data across different cycles, preventing precise recall of operation information for a specified quarter. Cause: Knowledge base grouping was not configured by data source type, or grouping rules were not bound to the source tags of uploaded files.
- Symptom: Single annual financial report file parsing fails, with an
ETIMEDOUTerror displayed in the interface. Cause: ThePARSE_FILE_TIMEOUT_SECONDSconfiguration value is lower than the actual parsing time required for the file.
How to Verify Correct Configuration
- Upload a test water utility monthly operation data file, trigger knowledge base synchronization, and verify that the source tag of this file is automatically associated in the knowledge base grouping.
- Initiate a query including "2023 average daily water supply volume", and verify that retrieval results only include text fragments matching this field and unit.
- Trigger a test with
answer_modeset to knowledge base only mode, input a standard financial question outside the knowledge base, and verify that the preset custom prompt content is returned. - Call the knowledge base file export interface, and verify that the returned file list includes all uploaded water utility financial report-related files.
