What Data in This Category Looks Like
Data sources for water industry research reports mainly include China Urban Water Supply and Drainage Association industry operation reports, annual and quarterly financial reports of listed water utilities, regulatory data publicly released by the Ministry of Ecology and Environment and local housing and urban-rural development departments, and special research reports from third-party industry consulting institutions.
Update rhythms fall into two categories: fixed cycle and real-time updates. Annual financial reports are released by April 30 of the following year. Quarterly financial reports are released within 45 days after the end of the quarter. Industry operation reports are updated at quarterly and annual nodes. Special policy research reports are updated immediately upon policy release.
Document structures usually include core operating indicators, regional market distribution, cost composition analysis, policy interpretation and project cases. Fields include publishing institution, publish date, indicator name, indicator value, corresponding unit, regional scope and others. Common units include 10,000 cubic meters per day, mg/L, %, yuan per cubic meter and similar.
Constraints Imposed on Citation Sources and Traceability by These Characteristics
Dispersed sources and varied formats require the traceability link to accurately match identification fields across different documents, to avoid confusing association reports with corporate financial reports.
Differences in update frequency require verifying document publish times during traceability, to ensure referenced regulatory data or operating indicators are the latest available.
Mixed structured indicators and unstructured interpretation in document structures require locating both specific text paragraphs and table cell positions during traceability, to avoid referencing fragments detached from indicator context.
Diverse field units require extracting the corresponding units for indicators during traceability, to prevent data ambiguity. For example, confusing "leakage rate 10%" with "leakage rate 10 mg/L".
Additionally, water industry research reports have strong regional attributes, with some data only applicable to specific provinces and cities. Traceability requires marking regional scope to avoid misuse of cross-regional data.
Configuration Settings
| Configuration Item | Recommended Value | Basis for This Setting | |||
|---|---|---|---|---|---|
recall count | Top 8-12 entries | Core indicators of water industry research reports are scattered across multiple paragraphs. Sufficient recall volume covers key data and interpretation content | |||
similarity threshold | 0.75-0.85 | The water industry has many professional terms. A threshold that is too low will introduce irrelevant industry reports, while a threshold that is too high will miss precise data in subdivided fields | |||
rerank return count | Top 5-7 entries | Filter semantically duplicated regional water project data, retain the most relevant research report fragments, and avoid redundant citations | |||
segment length | 1000-1500 characters | Indicator paragraphs in water industry research reports are mostly long text. Segments that are too long lose context association, while segments that are too short split complete indicator analysis units | |||
citation template | `{{source}} | {{publish_date}} | {{region}} | {{metric_unit}}` | Water industry research reports need to clearly mark source institution, publish time, coverage region and indicator unit to meet traceability accuracy requirements |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Large water industry annual reports include multi-page structured tables, parsing takes longer, avoid truncating document content due to timeout |
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, and testing on matching samples is recommended before finalizing.
Three Common Mistakes
- Phenomenon: When asking consecutive water-related questions, subsequent answers reference research reports unrelated to prior questions. Cause: Contextual recall configuration is not enabled, only documents relevant to the current question are recalled once, without associating the context scope of historical questions.
- Phenomenon: 504 Gateway Timeout error occurs when parsing large water industry annual reports. Cause:
PARSE_FILE_TIMEOUT_SECONDSis set below 120 seconds, parsing time for structured tables and long text exceeds the preset duration. - Phenomenon: Citation results do not mark the corresponding unit of the indicator. Cause: The
{{metric_unit}}variable is not included in the citation template, and unit information of the field is not extracted, leading to data ambiguity.
How to Confirm Configuration Is Correct
- Upload an annual financial report of a water enterprise, check if the parsed segments retain complete indicator analysis paragraphs, with no obvious content truncation or splitting errors.
- Test two consecutive related questions, such as first asking "2023 national average daily urban water supply", then asking "corresponding national pipe network leakage rate". Check if the research report sources referenced in both answers are associated with the same set of documents.
- Check the display format of citation results, confirm that key traceability information such as source institution, publish date, coverage region and indicator unit is included.
- Upload a special water industry research report with more than 100 pages, check if the parsing process completes within 120 seconds, with no timeout errors.
