What the Data for This Category Looks Like
Financial report data for the oil and gas extraction industry comes primarily from public annual reports, quarterly reports, and temporary announcements disclosed by listed companies, plus production statistics reports released by industry associations. Data updates follow two schedules: regular and irregular. Regular reports are released on a fixed quarterly or annual fiscal cycle. Temporary announcements are issued immediately when major production changes or reserve adjustments occur.
Document structures include sections such as management discussion and analysis, oil and gas production and sales prices, production cost breakdowns, capital expenditure plans, and proven reserve evaluations. Core fields include oil and gas production (usually measured in barrels or barrels of oil equivalent), unit sales price (USD per barrel), exploration and development expenditure amounts (USD), and reserve scale (billion cubic feet or barrels of oil equivalent). Some specialized terms require interpretation in line with industry standard definitions.
Constraints Imposed on Citation Source and Traceability
Publicly disclosed documents contain both structured data and unstructured paragraphs. Traceability requires precise location of the original text in specific sections, to avoid breaking term integrity by splitting content. The mixed schedule of regular and irregular updates requires the knowledge base to sync new announcements at a reasonable frequency. Otherwise, traceability results will lag behind the latest industry developments.
The multi-dimensional field and unit system requires citations to include corresponding units and disclosure context, to avoid unit confusion across different financial reports. Individual financial report documents are lengthy. Citation snippets must be controlled to a reasonable length, otherwise redundant content will be added or key analysis basis will be truncated.
The use of industry-specific terms requires traceability to link back to the original paragraph where the term appears. Extracting only general keywords cannot guarantee analysis accuracy.
Configuration Settings
| Configuration Item | Recommended Range | Rationale |
|---|---|---|
similarity_threshold | 0.75-0.85 | Oil and gas industry terms are highly specialized. A threshold that is too low will introduce unrelated industry reports. A threshold that is too high will miss segmented fields such as barrels of oil equivalent conversion ratios |
rerank_top_n | Top 6-8 results | Oil and gas financial report documents are lengthy and dense with terms. Too many retrieved results will introduce irrelevant content. Too few will miss key reserve and production data |
max_citation_chars | 1200-1800 characters | Key information in a single financial report paragraph, such as capital expenditure plans, typically runs around 1000 characters. This range preserves complete term-containing paragraphs |
rag_chunk_size | 800-1000 characters | Term paragraphs in oil and gas financial reports are usually coherent. Splitting too finely will break term integrity. Splitting too coarsely will introduce redundant content |
citation_template | [Document Name] Disclosure Time: [Time] Page Number: [Page Number] | Oil and gas financial report analysis requires clear disclosure time and location of sources to meet compliance verification requirements |
knowledge_base_refresh_rate | Daily | Temporary announcements such as drilling progress updates will affect analysis results. Latest data must be synced in a timely manner |
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 Configuration Errors
- Symptom: After enabling
rerank_top_n, retrieval results are empty or only return 1 entry. Cause:similarity_thresholdis set too high, and re-ranking filters all relevant snippets below the threshold, resulting in no valid citation sources. - Symptom: Citation sources lack disclosure time or document metadata is missing. Cause:
citation_templateis not configured to include the time field, or the knowledge base has not synced the disclosure metadata for documents. - Symptom: A single citation is truncated and loses core terms such as the definition of proven reserves. Cause:
max_citation_charsis not adjusted, and the default value for general categories is used, without adapting to the term structure of lengthy oil and gas financial report paragraphs.
How to Verify Proper Configuration
- Navigate to the knowledge base management page, check the
knowledge_base_refresh_ratesetting, and confirm the refresh frequency matches the data update schedule. - Submit a query related to oil and gas financial reports, review the citation section of the returned results, and confirm that each citation includes the document name, disclosure time, and page number information.
- Adjust the values of
similarity_thresholdandrerank_top_n, test the number of retrieved results across different thresholds, and ensure the number of retrieved results is stable and meets analysis requirements. - Manually upload a test oil and gas financial report document, verify that the
rag_chunk_sizesplitting preserves complete term-containing paragraphs such as unit conversion rules.
