Data Characteristics in this Domain
Infectious disease regulatory submissions involve diverse data sources with varying update frequencies. Key data types include clinical trial reports, epidemiological survey data, pathogen detection reports, drug mechanism of action studies, toxicology studies, and relevant guidelines and regulations. Epidemiological data and pathogen variation information update frequently, potentially quarterly or annually. Document structures commonly include structured reports (e.g., ICH E3 clinical study reports), semi-structured documents (e.g., literature reviews, expert consensuses), and unstructured text (e.g., meeting minutes, email communications). Critical fields include pathogen name, host, infection site, drug susceptibility, treatment regimen, and adverse event rates. Units cover concentration (μg/mL), dosage (mg/kg), time (hours, days), and percentage (%), requiring high precision.
Constraints on Citation and Traceability
The high update frequency of infectious disease data requires the knowledge base to rapidly ingest and index newly published epidemiological reports and pathogen variation data, ensuring timely citations. The coexistence of structured and semi-structured documents challenges document parsing capabilities, necessitating accurate extraction of key information and relationship establishment. For example, the system must extract efficacy and safety data for a specific drug in infectious disease treatment from clinical trial reports and trace it back to the original trial design and statistical analysis sections. Diverse fields and units demand correct identification and differentiation of numerical meanings in different contexts during knowledge graph construction or semantic understanding, preventing citation errors due to unit confusion. Furthermore, precise traceability of citation sources is crucial for regulatory compliance, requiring each citation to link to the specific page or paragraph of the original document.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size | 500-800 characters | In infectious disease reports, key information is often concentrated in shorter paragraphs. This length helps maintain contextual completeness. |
Recall count | Top 8-12 | Ensures coverage of critical arguments from multiple relevant documents, especially for multi-factor analysis. |
Similarity threshold | 0.75-0.85 | Domain terminology is highly specialized. A higher threshold reduces recall of irrelevant content, improving precision. |
Rerank result count | Top 5 | Focuses on the most relevant citations, reducing manual screening burden and improving efficiency. |
UPLOAD_FILE_MAX_SIZE | 500 MB | Clinical trial reports or large literature sets can have substantial file sizes, requiring support for large uploads. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing complex PDFs or scanned documents can be time-consuming. This provides sufficient parsing time to avoid timeouts. |
Common Pitfalls
- Incomplete question-answer pair generation in the knowledge base, with some files directly written as raw text: This often occurs when document content has a complex structure, such as numerous tables or images, preventing text extraction and chunking algorithms from identifying effective question-answer boundaries.
- Model testing fails after integration but works in citation: This could be due to an abnormal health check response from the model server while the actual inference service operates normally, or subtle errors in the
API_KEYorBASE_URLwithin the model configuration. - The knowledge base retrieves only one document per query in simple applications: This may relate to a low
Recall countconfiguration, or an overly aggressive document chunking strategy where a single retrieved chunk contains most of the document's information, leading the system to incorrectly assume only one source was cited.
Validation Steps
- Upload a typical infectious disease clinical trial report. Verify that the knowledge base successfully generates multiple question-answer pairs, and that their content accurately reflects key data (e.g., efficacy rates, adverse event rates) from the report.
- For a guideline document containing multiple literature references, query the system to confirm its ability to extract and synthesize information from different sources, ensuring each citation links to the correct original document.
- Simulate a query involving drug susceptibility analysis. Check that the returned citations include pathogen names, drug names, corresponding susceptibility values, and can be traced back to the original detection report or research literature.
- Monitor log outputs to confirm the absence of
TimeoutErrororParsingFailedmessages during file parsing, especially for large PDF files.
