What Data Looks Like for This Category
Snack food investment research data primarily comes from public industry research reports, e-commerce platform sales ledgers, supply chain manufacturer weekly shipment reports, supermarket sales records, and consumer public reviews. Update rhythms vary across data sources: e-commerce sales data is updated daily, industry research reports are updated weekly or monthly, supply chain shipment data is synchronized weekly, and consumer reviews are generated in real time. Document structures fall into three categories: structured SKU sales tables containing fields such as SKU ID, shipment volume, and display location type; semi-structured industry analysis sections covering category trends and competitor updates; unstructured consumer feedback text covering product taste, packaging reviews and other content. Some data has field format differences due to varying data sources.
Constraints on Model Access and Configuration
The multi-source heterogeneous characteristics of snack food investment research data require the model access link to support multi-format document parsing and field alignment. Daily updated e-commerce data needs a high-frequency synchronization mechanism to avoid data lag impacting research timeliness. Long-text consumer reviews and industry reports need appropriate chunking rules to prevent exceeding model context windows. A large number of SKUs with significant field format differences require unified field mapping rules to ensure accurate matching of target data during retrieval. Additionally, real-time consumer feedback needs to support incremental synchronization to avoid excessive compute resource usage from full synchronization.
How to Set Configurations
These configurations are compatible with FastGPT V4.9.3 and later versions:
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Matches the text length of snack food industry report paragraphs and consumer reviews, prevents single chunks from exceeding model context limits |
recallTopK | Top 6–8 results | Balances retrieval coverage and response efficiency given the large number of snack food SKUs, avoids retrieving too many non-core data points |
syncInterval | 1–24 hours | Aligns with update rhythms of daily e-commerce data and weekly supply chain data; sync cycles can be adjusted individually per data source type |
fieldMappingEnable | Enabled | Aligns field formats of SKUs, shipment volumes and other fields across different data sources, unifies field standards for knowledge base retrieval |
parseStructuredTable | Enabled | Supports parsing structured documents such as SKU sales tables and sales ledgers, retains core fields of original data |
similarityThreshold | 0.72–0.80 | Filters low-relevance non-snack food content while retaining valid retrieval results for the target category |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: Model connection failure or 500 status code displayed in the debug preview interface. Cause: The
apiBaseUrlparameter is not correctly configured to point to a locally deployed oneapi or ollama node, or a valid API key is not filled in. - Symptom: Knowledge base retrieval returns no results or a large amount of non-snack food category content. Cause: The
fieldMappingEnableparameter is not enabled, and field formats across different data sources are not aligned, leading to failure to match valid data during retrieval. - Symptom: The model does not reference knowledge base retrieval results in non-tool call mode. Cause: The snack food investment research knowledge base is not associated with the current application, or the
recallTopKvalue is set too low, resulting in failure to retrieve valid results.
How to Confirm Configuration is Complete
- Navigate to the FastGPT model management page, select the fully configured model to initiate a test call, confirm the returned status code is 200 and there are no connection error prompts.
- Upload a snack food SKU sales table to the knowledge base, run a parsing task, confirm that the parsed fields include original content such as SKU ID and shipment volume, with no fields missing.
- Initiate a retrieval request for a specific snack food product, confirm that the retrieval results include matching SKU data, industry report content or consumer reviews.
- Enable non-tool call mode, submit a test question about the snack food industry, confirm that the model's reply references relevant retrieval results from the knowledge base.
