Context and Token for Small Home Appliance Investment Research Knowledge Base Construction

Sources of small home appliance investment research data include brand-public product specification documents, industry association-published category

What the data for this category looks like

Sources of small home appliance investment research data include brand-public product specification documents, industry association-published category monitoring data, sales data from mainstream e-commerce platforms, compliance certification reports from third-party testing institutions, and track investment research reports released by securities firms. Update frequency includes daily updates for parameters and sales data during concentrated new product launch periods, weekly synchronizations during regular cycles, and monthly updates for investment research reports. Document structures include structured single-product parameter tables, long-text research reports with multiple paragraphs and charts, and fixed-format compliant PDFs or scanned documents. Fields cover product model, rated power (W), rated voltage (V), overall dimensions (mm), energy efficiency rating, launch date, supply chain cost proportion, and others. Units use international standard measurement symbols uniformly.

What constraints do these characteristics create for context and token processing

Small home appliance investment research data has mixed characteristics of structured short fields, long-text research reports, and high-frequency updates, creating multiple constraints during context and token processing. The large number of structured parameter fields with uniform units requires precise field matching during recall to avoid redundant splicing, which would otherwise increase invalid token consumption. High-frequency updated sales and new product data require recent information to be included in the context, expanding the coverage of the context window and increasing token usage. Differences in segmentation across heterogeneous documents can cause format confusion during context splicing, further increasing the proportion of invalid tokens. Additionally, the fast iteration speed of the small home appliance category requires limiting the time span of context recall to avoid outdated data occupying token resources.

How to set configurations

Configuration ItemRecommended ValueRationale
maxContext8000–12000 charactersSmall home appliance investment research data includes multiple sets of structured parameters and single research reports. This range covers the core context required for a single round of interaction and avoids token overflow
chunkSize800–1000 charactersSmall home appliance product parameters are mostly combinations of short fields. This segmentation length ensures that a single segment contains complete single-product parameters or a single chapter of research report content, reducing segmentation errors
similarityTopKTop 8–10 resultsThere are many competing product parameters in the small home appliance category. Too many recalled results will increase token consumption, while too few will fail to cover core comparison dimensions
rerankTopNTop 3–5 resultsFor the precise matching needs of structured parameters, re-ranking retains core competing products and research report data, reducing the proportion of invalid context
contextRecallTimeRangeLast 90 daysSmall home appliances iterate quickly. This time range filters outdated data and reduces invalid token occupation
tokenLimitPerRequest15000 charactersMatches the model's input token limit to avoid a single round of request exceeding the model's supported range

The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and testing on local samples is recommended before finalizing.

Three common configuration mistakes

  • Phenomenon: After self-hosted deployment, single-round interaction token consumption is higher than online version test data. Background monitoring shows the number of documents recalled in the context exceeds expectations. Cause: Default configurations of similarityTopK and rerankTopN were not adjusted, and too many non-core small home appliance competing product data were included in the context, increasing token consumption.
  • Phenomenon: Search results are not associated with the current small home appliance investment research context, returning generic industry content. Cause: The context-bound search configuration item was not enabled, and the search instruction did not carry the context parameters of the current session, causing search results to be disconnected from the current investment research scenario.
  • Phenomenon: After uploading compliant PDF documents, duplicate fields and units appear in context splicing. Cause: chunkSize was not set to adapt to the short-field structure of small home appliance parameter documents. When splitting segments, multiple sets of parameters of the same product were split into different segments, resulting in redundant content after splicing and increasing invalid token occupation.

How to confirm configuration is correctly set

  • Upload a single small home appliance product parameter document, trigger an investment research interaction, and check the total_tokens field in the background log to confirm the value is within the preset tokenLimitPerRequest range.
  • Initiate an investment research question involving a comparison of two small home appliance competing products, check the number of context recalled results in the returned results to confirm the quantity matches the configuration values of similarityTopK and rerankTopN.
  • Upload a document for a discontinued small home appliance product, initiate a query about related parameters, and confirm the returned results do not mention the product, verifying the contextRecallTimeRange configuration takes effect.
  • Test the search function, enter a query that includes the current session context, and confirm the search results are associated with specific parameters of the current small home appliance category or track research report content.
