What the Data for This Category Looks Like

Business data for brand agency operations covers brand sales ledgers, user reviews and transaction data from e-commerce platforms, competitor marketing materials, industry compliance documents, and public research reports. Data update cadence varies by business scenario: sales reports are updated daily, user reviews are synced in real time, and marketing materials are updated temporarily alongside launch plans. Document types include structured Excel sales reports, CSV-formatted review export files, semi-structured e-commerce product detail pages and social media copy, as well as unstructured PDF compliance documents and research reports. Fields include SKU codes, sales volume, customer unit price, review keywords, advertising budget, compliance clauses and more. Units include pieces, yuan, times, thousand impressions and others.

What Constraints Do These Characteristics Impose on the Document Parsing and Chunking Process

The multi-type data characteristics of brand agency operations impose multiple constraints on the parsing and chunking link. First, structured data contains strongly correlated fields such as SKU, sales volume and budget. Chunking must retain the complete semantics of field combinations to avoid breaking business meaning after splitting. Second, mixed-format data sources require parsing tools to support Excel, CSV and unstructured text formats at the same time. Failure to do so will result in loss of large amounts of business data. Third, frequently updated real-time data requires the parsing process to have batch fast processing capabilities to avoid task interruptions caused by timeouts. Fourth, mixed scenarios of compliance documents and marketing copy require chunking rules to accurately extract compliance clauses while retaining contextual associations of marketing content.

How to Set the Configurations

Configuration ItemRecommended SettingRationale
PARSE_EXCEL_SUPPORTEnabledMost brand agency operation data is stored as Excel-formatted sales reports and inventory ledgers. Full parsing of multiple worksheets and cell structures is required
PARSE_CSV_MAX_COLUMNSCalibrated via actual business testingBrand agency operation CSV data often contains multiple business fields such as SKU, sales volume and customer unit price. Adaptation to unrestricted column import requirements is needed
chunk_size800–1200 charactersMost brand agency operation documents include marketing copy and competitor analysis paragraphs. This length retains the complete semantics of a single business content item
chunk_overlap100–150 charactersPrevents critical contextual breaks after splitting, and adapts to text with front-to-back associations such as reviews and launch plans
PARSE_FILE_TIMEOUT_SECONDS600 secondsSufficient parsing and upload time must be reserved when batch processing multiple Excel reports
RECALL_SIMILARITY_THRESHOLD0.75–0.85Matches precise business keywords for brand agency operations, and avoids recalling irrelevant non-business documents

The parameter values provided on this page are general 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. It is recommended to test on your own samples before finalizing settings.

Three Common Errors

  • Symptom: The system prompts an unsupported format error when uploading Excel files, or cell formatting and multi-worksheet content are lost after parsing. Cause: The PARSE_EXCEL_SUPPORT configuration item is not enabled, and the default parsing rules do not adapt to complex Excel formats.
  • Symptom: Only the first two columns of data are retained after importing CSV files, and the remaining business fields are lost. Cause: The PARSE_CSV_MAX_COLUMNS parameter is not adjusted, and the default setting limits the maximum number of parsed columns.
  • Symptom: A connection failure error is returned when calling the parsing service, and the docker-deployed service cannot communicate normally. Cause: The parsing service port is not mapped to the local machine, or firewall rules block port communication requests.

How to Confirm the Configuration Is Properly Set Up

  • Upload a CSV test file containing multiple business fields, and verify that all column contents are retained in the parsed data.
  • Upload an Excel test file containing multiple worksheets, and verify that the parsing results include text content from all worksheets.
  • Enter the chunking preview interface, adjust the chunk_size parameter, and confirm that the chunk length falls within the preset 800–1200 character range.
  • Submit a batch parsing task, and verify that the task completion time does not exceed 600 seconds, and no timeout interruption prompts appear.
