What the data for this category looks like
Core data sources for oil and gas extraction research reports include industry exploration and development associations, specialized energy research institutes, and third-party energy consulting institutions. Updates follow a monthly or quarterly regular release schedule, with temporary incremental updates during major exploration breakthroughs or policy adjustments. Most documents are in PDF format, with nested structured tables and professional charts. Fields include exploration block coordinates, drilling depth, single-well production, barrel oil equivalent cost, reserve evaluation data, and more. Units include meters, cubic meters, USD per barrel, tons, and other professional measurement standards. Some documents contain industry-specific abbreviated terms and compliance markings.
Constraints imposed by these characteristics on citation source and traceability
Since data sources are scattered and update cycles are inconsistent, the traceability link must support associated binding and incremental synchronization verification across multiple knowledge base sources. Documents with nested structured tables and professional fields require retention of the mapping between original field names and units. Without this mapping, key parameter information will be lost in traceability displays. A high density of professional terms with clear semantic boundaries means retrieved segments must accurately match original text expressions. This avoids term deviations during traceability. Long documents account for a large share of the corpus. Segment processing must balance semantic integrity, otherwise cited traceability segments will not align with complete argumentation logic.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
relevantChunkCount | Top 8–12 results | Core information of a single oil and gas extraction research report is distributed across multiple segments. This range covers professional content across exploration, extraction, cost, and other dimensions |
similarityThreshold | 0.72–0.80 | Balances semantic matching accuracy for professional terms and recall coverage. It prevents low-relevance non-target research report segments from being included |
enableSourceCitation | Enabled | Oil and gas extraction research reports contain many irreplaceable professional parameters. This setting requires clear labeling of the source document’s publishing institution, publishing time, and block information |
parseTableEnable | Enabled with field mapping retained | Nested drilling data and reserve evaluation tables in research reports are core traceability content. This setting preserves the complete mapping between original field names and units |
chunkSize | 1000–1200 characters | Balances segment integrity and semantic coherence for long documents. It supports complete extraction of professional terms and avoids splitting that damages argumentation logic |
API_KEY_SCOPE | Bound to private knowledge base permissions | Restricts external API calls to only access specified private knowledge bases, meeting industry data confidentiality requirements |
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 case-by-case analysis, and it is recommended to test against your own samples before finalizing.
Three Common Misconfigurations
- Phenomenon: Matching research report entries appear in the citation list, but the corresponding content does not display in the answer body. Cause:
relevantChunkCountis set too low, so core argumentation segments are not included in the generation context, orenableSourceCitationis not bound to the answer generation logic. - Phenomenon: External API calls to private knowledge bases return a
403 Forbiddenstatus code. Cause:API_KEY_SCOPEis not configured to allow external calls to this private knowledge base, or the key permission scope does not cover the target research report library. - Phenomenon: Structured parameters such as drilling depth and reserve units do not appear in the citation source. Cause:
parseTableEnableis not enabled, so structured fields in tables are not extracted, making it impossible to associate corresponding parameters during traceability.
How to Confirm Correct Configuration
- Upload a single oil and gas extraction research report to the knowledge base. Check if the parsed text includes structured fields such as exploration blocks and drilling parameters to verify that the
parseTableEnableconfiguration is active. - Initiate a test query containing professional terms. Check if the end of the answer includes citation entries labeled with publishing institution and publishing time to verify that the
enableSourceCitationconfiguration is active. - Use an API key bound to a private knowledge base to initiate an external call. Verify that the returned results contain the expected research report content, confirming that the
API_KEY_SCOPEconfiguration is correct. - Adjust
similarityThresholdto 0.75, then initiate multiple test queries. Verify that the matching degree of recall results meets expectations, with no low-relevance irrelevant content included.
