What this type of data looks like
Data sources for semiconductor financing daily reports include public disclosure documents from domestic semiconductor industry associations, daily financing tracking reports from securities firms, and listed company announcements from the Shanghai, Shenzhen, and Beijing stock exchanges. The update schedule is before 18:00 daily, covering financing events in the semiconductor sector from the current and previous day. Most documents have structured tables embedded in paragraphs, or plain text event lists. Some include PDF format announcement attachments. Fields include full name of financing entity, affiliated semiconductor sub-sector, financing amount (unit: ten thousand RMB or ten thousand USD), financing round, investor list, disclosure date, and associated announcement link.
Constraints imposed on document parsing and chunking
The daily high-frequency update requirement demands low-latency processing for the parsing workflow. This prevents delays that prevent same-day data from being stored in databases. Mixed structured tables and plain text paragraph document structures require accurate distinction between the two content types. This avoids splitting associated information from the same financing event. Some documents include external PDF announcement links. The workflow must support automatic parsing of external link files, while being compatible with different attachment formats. The multi-unit attribute of financing amounts requires retaining the unit field during parsing. This avoids unit confusion in subsequent retrieval. Metadata for semiconductor sub-sectors must be embedded as key identifiers in chunked content. This improves the accuracy of subsequent semantic retrieval.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | The average processing time for a single semiconductor financing daily document (including external link parsing) is approximately 120 seconds. 300 seconds covers extreme large files or scenarios with multiple external links. |
Ideal Chunk Length | 800–1200 characters | The core information of a single semiconductor financing event is approximately 300-800 characters. This length can fully contain 1-2 related events, avoiding semantic fragmentation. |
PARSE_EXTERNAL_LINK_ENABLE | Enabled | Most semiconductor financing daily reports include external links to exchange announcements or industry reports. Automatic pulling and parsing of these links is required to supplement content. |
PARSE_ALLOWED_EXTENSIONS | txt, docx, xlsx, pdf | Common release formats for semiconductor financing daily reports are the types listed above. This covers both upload and external link parsing scenarios. |
TABLE_PARSE_MODE | Structured extraction | Most semiconductor financing daily reports include financing event tables. Structured extraction preserves field correspondence, avoiding loss of metadata during chunking. |
CUSTOM_SEGMENT_RULE | Segment by financing event line breaks | Most single events in semiconductor financing daily reports are separated by line breaks. This rule enables accurate splitting of independent events, avoiding chunking across events. |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, 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 Mistakes
- Phenomenon: After uploading or parsing an external link, the returned file link displays "Only support .txt, .m" when clicked. Cause: The
PARSE_EXTERNAL_LINK_ENABLEconfiguration is not enabled, or the allowed extensions do not include the corresponding file format. This results in the parsed external link file not being correctly identified. - Phenomenon: After parsing a semiconductor financing daily PDF that includes charts, knowledge base retrieval cannot return content associated with images. Cause: The image text extraction configuration is not enabled, or the parsing process skips extracting image annotation information. This means key visual content is not included in the chunked data.
- Phenomenon: After setting the custom segmentation rule, the chunking results still show splicing across financing events. Cause: The ideal chunk length is set incorrectly. A value that is too small causes a single event to be split. A value that is too large causes multiple events to be merged. Alternatively, the segmentation rule is not configured to use the document's native line breaks.
How to Confirm the Configuration is Correct
- Upload a test semiconductor financing daily document, view the parsed chunk preview, and confirm that no single financing event is split across multiple chunks.
- Paste a test data entry that includes an external announcement link, confirm that the parsing workflow can automatically pull and parse the external link content.
- Check the parsed field information, confirm that metadata such as financing amount and affiliated semiconductor sub-sector is fully retained, with no missing entries or unit confusion.
- Trigger a large model retrieval for this knowledge base, confirm that the returned content includes financing event details from the document, with no key information omitted.
