Citation Source and Traceability for Cement Industry

What the data for this category looks like

Cement industry research report data comes from the China Building Materials Federation, regional building materials associations, annual reports of listed cement enterprises, and third-party industry consulting institutions. Updates follow a monthly regular schedule. Quarterly industry-wide analysis reports are released. Ad-hoc reports are added when raw material prices shift suddenly or policies are adjusted.

Document structures typically include core data tables, supply and demand analysis, policy interpretations, and future market forecasts. Core data tables cover cement ex-factory prices and capacity utilization rates across regions and grades. Fields include cement grade, region, price unit (yuan/ton), publishing institution, and release date. Some reports include additional segmented data such as production capacity and inventory.

What constraints do these characteristics impose on citation source and traceability

The core data of cement research reports is tied to precise fields like region and grade. Traceability must match these segmented dimensions. Otherwise, cited passages will deviate from the user’s specific query scenario.

Update cycles are fixed with clear release times. The traceability process must filter expired data to avoid using outdated price or production capacity information.

A single research report contains multiple independent segmented data units. Traceability must support matching by content passages, not entire documents. This prevents irrelevant regional or grade data from being included.

Some reports include multi-dimensional cross data. Traceability results must accurately align with the query’s specific fields. Irrelevant full passages must not be returned.

How to configure settings

Configuration Item	Recommended Value	Rationale
`Recall count`	Top 10 entries	Cement research report data includes segmented dimensions such as region and grade. A sufficient number of candidate passages are needed to match precise query demands
`Similarity threshold`	0.72–0.85	Filter irrelevant research report passages with insufficient matching accuracy, while retaining enough candidates to cover queries across different segmented dimensions
`Rerank result count`	Top 3 entries	Core data of a single cement research report is concentrated. Prioritize returning precise passages that best match the query dimensions
`Citation Fragment Length`	600–1000 characters	Cover complete data units including cement grade, region, and price, to avoid truncating critical information
`Source Document Metadata Extraction`	Enabled	Extract fields such as region, grade, and release date from research reports for precise traceability matching
`API Return Citation Field`	Enabled	Return the filename and passage position of the associated document according to API call requirements, to meet traceability needs for external calls

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. It is recommended to test on your own samples before finalizing settings.

Three common mistakes

Symptom: API call results do not include the cited filename or passage position. Cause: The API Return Citation Field configuration item is not enabled, and the metadata return switch is not activated.
Symptom: Returned cited passages do not match the region or grade specified in the user’s query. Cause: Secondary filtering by cement-specific fields such as region and grade is not configured, and passages with similar matching accuracy but incorrect dimensions are recalled.
Symptom: Multiple segmented field contents from different research reports cannot be cited in a single answer. Cause: Traceability binding configuration for multiple recalled passages is not enabled, and only metadata for a single passage can be bound.

How to confirm the configuration is correct

Upload a standard cement industry research report document. Verify if parsed metadata includes region, grade, and release date fields. Confirm the Source Document Metadata Extraction configuration is active.
Submit a test query: "2024 East China P.O42.5 cement ex-factory price". Review returned cited passages to confirm they match the specified region and grade. Verify the Similarity threshold and Recall count configurations are properly set.
Initiate the same query via an API call. Check returned results for the filename and passage position of the cited document. Confirm the API Return Citation Field configuration is enabled.
Submit a query with multi-dimensional requirements, such as "2024 North China and East China P.O42.5 cement price comparison". Review returned results to confirm they include research report passages for both regions. Verify the multi-passage traceability configuration is active.
