Document Parsing and Chunking for Aquaculture Research Report Retrieval

Aquaculture research report data sources include the Ministry of Agriculture and Rural Affairs Aquaculture General Station, provincial and municipal

What the data for this category looks like

Aquaculture research report data sources include the Ministry of Agriculture and Rural Affairs Aquaculture General Station, provincial and municipal aquaculture technology promotion stations, policy and market documents released by industry associations, research meeting minutes from securities firm agriculture, forestry, and animal husbandry research teams, and monthly production reports from large-scale aquaculture enterprises. Data update cycles cover weekly (aquaculture water quality indicators, weekly market reports), monthly (enterprise production data) and quarterly/annual (industry trend reports). Document formats include PDF policy files, Word research meeting minutes, Excel production statistics tables, and real-time web market data. Common fields include breeding density, yield per mu, feed coefficient, and dissolved oxygen in water. Corresponding units are tail/mu, kg/mu, no unit, and mg/L.

Varying document formats across multiple sources require the parsing process to support PDF, Word, Excel and web data, with targeted extraction of structured fields. Documents with different update frequencies need matching chunking logic to attach timeliness tags, avoiding cross-cycle data confusion. Professional fields with specific units are tightly bound to their context. During chunking, continuous context of fields and units must be retained to prevent mismatches between units and data during retrieval. A large volume of production statistics data presented in tables requires retaining table structure during parsing, avoiding loss of row and column association information after text-based splitting.

Configuration Settings

Configuration ItemRecommended ValueRationale
PARSE_TABLE_ENABLEEnabledTables account for a large share of aquaculture research reports, retaining structured tables improves retrieval accuracy
CHUNK_SIZE800–1200 charactersCovers professional terminology, units and associated context, avoids splitting professional phrases or truncating field information
PARSE_FILE_TIMEOUT_SECONDS120 secondsAdapts to parsing time of large research meeting minute PDFs, prevents interruptions during long document parsing
ENABLE_CHUNK_ID_COPYEnabledAllows users to copy chunk IDs to associate with custom indexes, meets business docking requirements
ALLOW_DUPLICATE_CHUNKEnabledRetains original chunk order from custom splitting, avoids index misalignment caused by automatic deduplication
TABLE_RENDER_MODEText-based table markupAdapts to aquaculture data exported via pandas, converts structured tables into searchable text format

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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.

Three Common Configuration Errors

  • Phenomenon: The chunk ID cannot be copied via the interface in the knowledge base details page. Cause: The ENABLE_CHUNK_ID_COPY configuration item is not enabled.
  • Phenomenon: Duplicate entries are automatically removed after custom-split document chunks are stored in the knowledge base, causing the pre-configured index order to not match the actual stored content. Cause: The ALLOW_DUPLICATE_CHUNK parameter is not enabled, and the system performs automatic deduplication by default.
  • Phenomenon: Professional fields with units such as dissolved oxygen and breeding density in aquaculture research reports are split into different chunks, and unit information cannot be associated during retrieval. Cause: The chunk length is set too small, truncating the continuous context of fields and units.

How to Verify Correct Configuration

  • Upload a PDF of an aquaculture industry research report, view the parsed chunk list, confirm that a copy button is displayed next to each chunk ID, verifying that the ENABLE_CHUNK_ID_COPY configuration takes effect.
  • Upload a document that was pre-custom split, check that the number of chunks stored in the knowledge base matches the number of custom split chunks, verifying that the ALLOW_DUPLICATE_CHUNK configuration is correct.
  • Submit a search request for professional fields, check whether the returned results contain complete field and unit association content, verifying that the chunk length configuration meets requirements.
  • Upload a document containing tables exported via pandas, check whether tables in the search results are presented in structured form, verifying that the TABLE_RENDER_MODE configuration takes effect.
