What the data for this category looks like
Engineering consulting marketing content data primarily comes from project feasibility study reports, tender response documents, customer success case libraries, industry policy interpretation documents, and standardized marketing script libraries. Update cadence varies by content type: winning project cases are updated alongside project delivery, industry policy documents are adjusted in line with regulatory requirements, and marketing scripts are iterated quarterly. Individual documents typically include structured fields such as project number, consulting scope, customer name, deliverables, price range, and applicable scenarios. Some long documents also include multi-chapter technical details and marketing highlights. Consulting cycles are measured in workdays, project scales are measured in square meters and 100 million yuan, and quotations are measured in 10,000 yuan per project.
What constraints these characteristics impose on knowledge base retrieval and recall
Document structures are complex and include multiple structured fields. Fixed-length chunking can easily break business associations, so chunking must combine semantic and field associations. Data update cadences vary widely, so static policy documents and dynamic project cases must be categorized as hot or cold data, and recall weights adjusted accordingly. Marketing content is intended for customer communication, so retrieval results must align with business scenarios, and overly technical internal documents should be excluded. Fields include specific units, so retrieval must match unit-related semantics to avoid retrieving mismatched consulting content.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
segment length | 800–1200 characters | Engineering consulting documents are mostly long texts containing multi-paragraph project plans and policy interpretations. This length preserves semantic integrity and avoids splitting that disrupts business logic. |
chunkOverlap | 100–150 characters | Retains overlapping content between adjacent chunks, prevents cross-paragraph marketing scripts from being split apart, and ensures semantic coherence during recall. |
recall count | Top 6–8 results | Engineering consulting marketing content requires a balance between comprehensiveness and precision. Too many results lead to redundant responses, while too few fail to cover potential customer inquiry scenarios. |
similarity threshold | 0.72–0.78 | Matches the density of professional terminology in engineering consulting. A threshold that is too low will introduce irrelevant general consulting content, while a threshold that is too high will fail to retrieve marketing materials for niche scenarios. |
reranked return count | Top 3–5 results | Filters content that most closely matches user marketing inquiry needs, and avoids non-core technical details interfering with marketing communication. |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Engineering consulting documents often include multi-page tender plans and feasibility study reports. A longer timeout ensures complete parsing. |
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 case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- An error with
message: Invalid URL, code: 500is returned when uploading knowledge base files via theapiCollectioninterface. Cause: The file storage path associated with the knowledge base was not configured correctly, or the incoming file URL did not pass the platform's whitelist verification. - Retrieval results only match the main content of chunks, and do not associate with auxiliary field information. Cause: The auxiliary data retrieval configuration item was not enabled, or auxiliary fields such as project number and customer name were not correctly extracted during chunking.
- Generated responses retain reference links from the source knowledge base documents. Cause: The reference link output switch in responses was not turned off, or relevant parameters for disabling source document jumps were not disabled during configuration.
How to confirm configurations are set correctly
- Access the knowledge base management interface, review the chunk preview of uploaded engineering consulting documents, and confirm that chunks retain complete business paragraphs and auxiliary fields.
- Initiate a test query simulating a marketing inquiry, and verify that the number and similarity of returned recall results match preset configuration expectations.
- Call the
apiCollectioninterface to query the knowledge base list, and confirm that the target knowledge base ID parameter can be retrieved normally. - Generate a test response, and check that it includes the expected marketing content, with no extraneous reference links or invalid error messages.
