Citation Source and Traceability for Coal Chemical Industry

What the data for this category looks like

Coal chemical industry research report sources primarily include official reports from industry associations, specialized industry research from securities firms, analyses from professional consulting institutions, and internal operational data from large coal chemical enterprises. Update cycles cover monthly industry supply and demand monitoring, quarterly industrial chain trend analysis, and irregular special research reports. Document structures typically include abstracts, core data sections, industrial chain maps, policy interpretations, and risk warnings. Core fields include report number, issuing institution, release date, production capacity value (unit: ten thousand tons/year), product price (unit: yuan/ton), and some reports include upstream and downstream industrial chain related data.

What constraints do these characteristics impose on the citation source and traceability link

The multi-source, dispersed nature of coal chemical industry research reports requires the traceability system to uniformly recognize report identifiers across different institutions to avoid traceability confusion. The long document structure means retrieved segments must accurately locate specific chapters or page numbers; otherwise, complete original content cannot be associated. Differences in update frequencies require the traceability system to support automatic synchronization of newly released reports to ensure the timeliness of retrieved content. The use of specialized terminology and specific units requires that original data units and terminology expressions be retained during traceability to avoid information distortion. In addition, coal chemical industry research reports involve strongly correlated industrial chain data, so traceability must link to corresponding upstream and downstream sections to improve response credibility.

How to configure the settings

Configuration Item	Recommended Value	Rationale
`recall count`	`Top 10–15 results`	Coal chemical industry research reports are professional and lengthy. Excessive recall introduces redundant information and reduces response focus
`similarity threshold`	`0.65–0.75`	Terminology in the coal chemical field is highly specialized. A threshold that is too low introduces irrelevant content, while a threshold that is too high reduces valid recall results
`reordered return count`	`Top 5–8 results`	Only the most relevant and authoritative sources are retained to avoid dispersing the focus of the response
`UPLOAD_FILE_MAX_CHUNK_SIZE`	`800–1200 characters`	Coal chemical industry research reports contain long paragraphs of industry data. This chunk length preserves context integrity
`SOURCE_ID_FIELD`	`report number`	Coal chemical industry research reports generally have unique report numbers, which serve as the core identifier for precise traceability
`PARSE_FILE_TIMEOUT_SECONDS`	`120 seconds`	Parsing large coal chemical industry research reports takes a long time. This duration covers the parsing needs of most long documents

The parameter values provided on this page are conventional recommendations used as a starting point 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

Phenomenon: After adjusting the similarity threshold to the minimum and recall count to the maximum, the retrieved content remains fixed at a set number. Cause: The enable_recall_expand parameter is not enabled, or the max_context setting limits the total retrieved character count, making it impossible to break through the recall upper limit.
Phenomenon: The output content includes raw markdown syntax instead of rendered display effects. Cause: The system prompt does not explicitly require markdown format rendering, or the raw_output parameter is enabled, resulting in output of original parsed content.
Phenomenon: The sourceid cannot be used to associate the corresponding field of the uploaded file. Cause: The SOURCE_ID_FIELD is not configured as the specified unique identifier field during upload, making it impossible to match the field information in the database during traceability.

How to verify the configuration is correct

Upload a test coal chemical industry research report, check the parsed data panel to confirm that the field corresponding to SOURCE_ID_FIELD has been correctly extracted.
Submit a coal chemical industry professional query, check the retrieval result panel to confirm that the recall count matches the configured recall count value.
Check the system prompt to confirm that it includes explicit requirements for markdown rendering, then submit a query to verify whether the output format meets expectations.
Conduct multiple consecutive rounds of queries, check whether the knowledge base remains effective during the session, and confirm that the session context is correctly bound.
