What the data for this category looks like
Marketing content data for decoration and renovation in the financial sector mainly comes from project case documents, quotation sheets, unit type analysis manuals from cooperating decoration companies, as well as home improvement installment activity plans and promotional copy from financial institutions themselves. The data update rhythm adjusts in real time alongside new property partnerships, activity launches, and renovation process iterations, with no fixed cycle. Document structures include structured Excel quotation tables, PDF case sets with hierarchical headings, and long-text marketing tweets. Core fields include unit type area (unit: ㎡), renovation budget (unit: ten thousand yuan), installment interest rate, construction period (unit: days). Some documents also include customer feedback and text descriptions of on-site construction photos.
What constraints do these characteristics impose on document parsing and chunking?
The mixed structured and unstructured characteristics of decoration and renovation marketing content in the financial sector create multiple constraints for document parsing and chunking. Merged cells and multi-row service items in Excel quotation sheets easily trigger field misalignment or content merging during chunking, especially in scenarios where financial information including installment rates is bound to decoration services. Key identifiers such as package titles and unit type descriptions in long-text promotional copy require precise separation logic to retain complete context for decoration services and financial rates. Frequently updated document content requires the parsing process to quickly adapt to new format specifications. Image text descriptions embedded in some documents must be chunked together with the main text to avoid breaking key budget and rate information.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
segment_length | 800–1200 characters | Financial decoration marketing documents include long-text promotional copy and structured tables. This range retains the complete context of decoration services and installment rates within a single package |
custom_delimiters | \n【家装套餐】, \n【户型方案】, \n--- | Financial decoration marketing documents often use package titles and unit type titles as natural separation identifiers for content blocks, enabling accurate splitting of independent business units |
PARSE_EXCEL_MERGE_CELL | Enabled | Decoration quotation Excel files often use merged cells to mark service categories. Enabling this option retains the hierarchical association of fields and avoids misalignment between installment rate and decoration service fields |
chunk_overlap | 100–150 characters | Key information such as budget and installment rates in financial decoration marketing content often appears at the start and end of chunks. Setting overlap prevents context breaks |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | A single financial decoration marketing document usually does not exceed 50MB. This duration covers the complete parsing and chunking process |

Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- The phenomenon: After importing an Excel-format decoration quotation sheet, decoration services and installment rates in the same row are split into multiple chunks, or multi-row content is merged into a single chunk. Cause: The custom delimiters are not configured to adapt to Excel row separation, or the Excel row-by-row parsing parameter is not enabled.
- The phenomenon: After uploading multiple decoration marketing documents, exclusive information for each individual document cannot be extracted one by one. Cause: The multi-document independent parsing configuration is not enabled, or an independent identification field is not set for each document.
- The phenomenon: Chunked content contains redundant format symbols, leading to subsequent retrieval and matching failures. Cause: The
PARSE_CLEAN_EXTRA_SPACEconfiguration is not enabled, or redundant format characters are set in custom delimiters.
How to Verify Correct Configuration
- Upload a single decoration quotation Excel file, check whether chunking results split service items by row, and confirm that configuration items match the current document type.
- Import long-text decoration marketing promotional copy, check whether key information such as unit type area and installment rate is completely retained in a single chunk.
- Batch upload multiple decoration documents, check whether the parsing status and chunking results of each document are generated independently, with no content confusion across documents.
- Test the retrieval and matching process, confirm that normal recall occurs when input content matches chunked content, and adjust corresponding parameters to the range that meets business requirements.
