Party Building Learning Q&A for Coal Mine Production: Vector Models and Indexes

Party Building Learning Q&A for Coal Mine Production: Vector Models and Indexes This document is written based on FastGPT v4.17.0.

Reference only; verify against the target FastGPT release and deployment documentation.

What this category of data looks like

Data mainly comes from party building policy documents issued by the mine party committee, party building learning records from pre-shift meetings of each production work area, party members’ online learning ledgers, and special archives integrating safety production and party building. Update cadence follows three schedules: upper-level policy documents issued as needed, branch learning records updated weekly, and real-time submitted party member learning feedback. Document structures include plain text notices, learning materials with tables, and party lecture transcripts converted from audio. Fields include issuing unit, release time, and applicable work area. Units involved include copies, items, and person-times.

Constraints on vector models and indexing

Long audio-transcribed party lecture transcripts in the documents may cause single input length to exceed the basic chunking threshold, so long text splitting rules must be adapted. Fields include targeted labels for applicable work areas, so layered indexes must be built based on business dimensions to narrow recall scope. Real-time updated party member learning feedback data requires support for incremental index triggers to avoid resource consumption from full index rebuilding. Learning materials with tables require vector extraction logic that retains table semantics to prevent loss of structured party building knowledge points.

Configuration settings

Configuration ItemRecommended ValuesRationale
Chunk length800–1200 charactersAdapt to long text and structured content of coal mine party building documents, avoid breaking single-block information
Overlap length100–200 charactersRetain semantic association between adjacent chunks, prevent splitting and missing party building knowledge points
Similarity threshold0.72–0.80Filter low-relevance non-party building content, focus on core party building Q&A results
Single search limitTop 8 entriesMatch the content scale of the coal mine party building knowledge base, control redundancy of recall results
maxToken4096 tokenAdapt to input limits of mainstream external vector models, avoid truncation of critical content
defaultToken1024 tokenServe as the base length for default recall context, balance answer accuracy and resource usage

Three common mistakes

  • Phenomenon: After importing Excel files and multi-dimensional documents from the Feishu folder, the index result is empty. Cause: The parsing switch for the corresponding document format is not enabled, and the structured parsing rules for coal mine party building documents are not matched.
  • Phenomenon: Frequent timeout errors occur after connecting an external vector model. Cause: A reasonable maxToken parameter is not set, exceeding the model's input limit causes truncation and retries.
  • Phenomenon: Full index rebuilding takes too long, and server resource usage is too high. Cause: Incremental index trigger logic is not configured, and full rebuilding is performed for real-time updated party member learning feedback data.

How to confirm the configuration is correct

  • Upload a typical coal mine party building document, check whether the chunked text length meets the preset chunk length requirements.
  • Submit a test question related to party building, verify whether the number of recall results matches the single search limit setting.
  • Import a party building learning material with tables, check whether the index result retains the structured information in the table.
  • Adjust the defaultToken parameter, check whether the loading length of the Q&A context meets expectations.
