What data for this category looks like
Data for decoration and renovation research reports mainly comes from annual market reports released by industry associations, quarterly price bulletins from building material suppliers, project completion case documents from renovation companies, and renovation construction compliance documents issued by housing and urban-rural development authorities. Update cadence is inconsistent. Policy documents are released in line with regulatory requirements. Building material price data is updated monthly. Project case documents are released irregularly as construction projects are completed. Most documents contain structured tables, long-text process descriptions, budget data with units, and clear chapter hierarchies. Fields include numerical values tied to corresponding units.
What constraints do these characteristics impose on document parsing and chunking
Decoration and renovation research reports have a high proportion of structured tables. The parsing process must fully retain the row-column structure and cell content of tables, to avoid splitting table content into scattered text. There are many numerical fields tied to units. Chunking must ensure that numerical values and their corresponding units are in the same chunk, to prevent separation of unit prices and units during retrieval. Long-text construction process descriptions and project cases follow coherent logic. Chunking should not arbitrarily break chapter boundaries, and reasonable splitting should be done in line with the original chapter structure of the document. Some documents contain embedded images and descriptive text. Associations between images and their corresponding descriptions must be established, to avoid returning only image links without contextual support during retrieval.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_TABLE_ENABLE | Enabled | Decoration and renovation research reports contain a large number of material quotation and budget tables, and structured content must be retained |
CHUNK_SIZE | 800–1200 characters | Single-segment process descriptions and project cases in research reports mostly fall within this range, to avoid splitting critical logic |
CHUNK_OVERLAP | 100–150 characters | Retain contextual connections across chunks, to adapt to long construction step descriptions |
PARSE_KEEP_UNIT | Enabled | Fields such as material unit prices and construction durations in research reports are tied to units, to prevent separation of units and numerical values |
PARSE_TIMEOUT_SECONDS | 120 seconds | Single research reports often contain multi-page project cases, requiring sufficient parsing time |
RECALL_CHUNK_TOPK | Top 6 results | Match precise retrieval needs in decoration and renovation scenarios, to avoid redundant results |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material formats, data volume and business rules. Specific issues require targeted analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Symptom: After uploading a decoration and renovation research report that includes images, the knowledge base can recognize the image links, but question-and-answer tests cannot call content related to the images. Cause: The
PARSE_KEEP_IMAGE_CAPTIONconfiguration is not enabled, causing the image description text and image links to be separated, and no valid association can be established. - Symptom: When parsing large-scale renovation budget tables, the console returns a
PARSE_TABLE_PARSE_FAILEDerror. Cause: ThePARSE_TABLE_MAX_ROWSparameter is not adjusted, and the default value cannot adapt to large budget tables with more than 20 rows. - Symptom: When retrieving construction process content after chunking, steps are split across two non-consecutive chunks. Cause: The
CHUNK_OVERLAPparameter is set to below 50 characters, and insufficient contextually connected content is retained.
How to confirm configurations are properly set
- Upload a sample decoration and renovation research report that includes tables, images and construction process descriptions, and check whether the table structure in the parsing results is complete, and whether image links are accompanied by corresponding descriptive text.
- Retrieve keywords for material unit prices in the research report, and confirm that the returned chunked content contains numerical values and their corresponding units in the same text segment.
- Test retrieval of keywords for long-text construction steps, and check whether the returned chunked content contains a coherent logical chain, with no obvious step breaks.
- Check the background logs of the parsing task, and confirm that there are no error messages such as
PARSE_TIMEOUTorCHUNK_SPLIT_ERROR.
