Knowledge Base Retrieval and Recall for Smart Due Diligence Reports in Communications Equipment

What the data for this category looks like

Data sources for communications equipment smart due diligence reports include official manufacturer technical specifications, Ministry of Industry and Information Technology network access approval documents, carrier procurement parameter sheets, and third-party testing compliance reports. Documents are divided into three structural categories: technical parameter pages, compliance statement pages, and operation and maintenance guidance pages. Technical parameter pages contain fields such as frequency band range, transmit power, interface type, and power consumption, with explicit units including MHz, dBm, and kg. Data updates are adjusted dynamically alongside new product launches, network access license updates, and publicized procurement winning bid results. There is no fixed update cycle.

Constraints imposed on knowledge base retrieval and recall

Communications equipment parameters are mostly hard indicators with fixed units. The retrieval process must support exact matching of fields and units, to avoid parameter confusion caused by fuzzy matching. Multi-source documents have large structural differences. Retrieval logic must adapt to both structured parameter tables and unstructured compliance text. Document volume grows as the number of equipment series increases. Both incremental updates and full indexing must balance efficiency and completeness. Some compliance documents require associated retrieval with technical parameters. Cross-document associated recall logic must be configured to ensure due diligence reports cover both technical indicators and compliance requirements.

Configuration Settings

Configuration ItemRecommended Value RangeRationale
segment length800–1200 charactersCommunications equipment technical documents often contain continuous parameter paragraphs. This segment length covers a complete set of radio frequency indicators or interface specifications, preventing parameter splitting
similarity threshold0.75–0.85Communications equipment parameters are hard indicators. A higher matching precision is required to avoid recalling irrelevant equipment parameters with low similarity
PARSE_FILE_TIMEOUT_SECONDS300 secondsSingle manufacturer technical specifications may contain multi-page parameter tables, requiring a longer parsing timeout
recall counttop 8 entriesCovers multi-dimensional parameters of the same equipment model, while avoiding excessive results that disrupt due diligence judgment
UPLOAD_FILE_MAX_SIZE500 MBSupports uploading complete single packages of technical documents for an entire manufacturer's equipment series
reranked return counttop 3 entriesFocuses on the most matching core parameters, adapting to the rapid reference needs of due diligence reports

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.

Three Common Misconfigurations

  • An upstream connect error or disconnect/reset before head error occurs when uploading compliance documents. The cause is failure to adjust the UPLOAD_FILE_MAX_SIZE configuration, leading to connection timeout during large file chunked upload.
  • Parameter entries with mixed frequency band units appear in retrieval results. The cause is failure to configure field-level matching rules, with fuzzy matching incorrectly associating indicators with different units.
  • Retrieval efficiency is low for QA split file sets created via OpenAPI. The cause is failure to set a reasonable segment length, leading to too many index shards that require traversal of large amounts of redundant shards during retrieval.

How to Verify Proper Configuration

  • Upload a single communications equipment technical document larger than 100 MB, and check that parsing completes normally with no timeout errors.
  • Enter a search query containing a specific frequency band unit, and verify that retrieval results only return parameter documents matching that unit.
  • Call the knowledge base retrieval interface, count single retrieval latency, and adjust recall count and segment length to ranges that meet business requirements.
  • View knowledge base index logs, and confirm that incremental updates only target newly uploaded documents, with no repeated parsing of previously uploaded historical files.
