Data Characteristics for This Category
Solid tumor R&D document data primarily comes from clinical trial reports, pathology analysis reports, gene sequencing data, drug mechanism of action research papers, and regulatory submissions. Data update frequencies vary. Clinical trial data typically updates with phased reports, while basic research papers publish continuously. Document structures are complex, often containing extensive unstructured text, tables, images, and graphs. Fields include tumor type (e.g., TNM staging), molecular markers (e.g., EGFR mutation status), treatment regimens (e.g., dose, cycle), and efficacy evaluations (e.g., RECIST criteria). Units are diverse, including mg/kg, Gy, mm, and %.
Constraints Imposed by These Characteristics on "Reference Sourcing and Traceability"
The complex structure and diverse data sources of solid tumor R&D documents demand high precision in reference identification and traceability. For example, multi-round treatment regimens and evaluation results in clinical trial reports require the system to differentiate data sources from various stages. Extensive specialized terminology and abbreviations in gene sequencing reports need accurate linking to original definitions. Inconsistent document update frequencies necessitate version management within the knowledge base to ensure references point to the latest or specified data. For documents with charts and tables, text chunking requires careful attention to avoid splitting critical information, which could lead to loss of context in cited fragments and difficult traceability.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Chunk Size) | 800–1200 characters | Prevents over-segmentation of complex solid tumor descriptions and multi-field information, maintaining contextual integrity. |
Recall count (Recall Count) | Top 8–12 items | Solid tumor R&D questions may involve multiple chains of evidence; increasing recall covers a wider range. |
Similarity threshold (Similarity Threshold) | 0.75–0.85 | The solid tumor domain has much specialized terminology, requiring a higher similarity to ensure citation precision. |
maxContext | 4096 tokens | Allows the model to process longer solid tumor clinical report segments, providing sufficient context for reasoning. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Addresses large solid tumor research reports and complex PDF parsing, preventing parsing failures due to timeouts. |
Rerank result count (Reranked Return Count) | Top 5 items | Further refines the most relevant solid tumor research evidence from the initial recall. |
Common Pitfalls
- The citation results contain many irrelevant or duplicate fragments. This occurs when the
Similarity threshold(Similarity Threshold) is set too low, leading to the recall of non-core information. - A "citation limit insufficient" prompt appears during knowledge base calls, indicating fewer citations returned than expected. This usually means the
Recall count(Recall Count) parameter is set too conservatively, failing to cover enough solid tumor-related literature. - After parsing large solid tumor clinical trial reports, some critical table data is not correctly structured or is cited as empty. This might be because
PARSE_FILE_TIMEOUT_SECONDSis too short, leading to incomplete file parsing.
Verification Steps
- For typical solid tumor R&D questions, verify that cited sources accurately pinpoint specific paragraphs or tables in the original documents.
- Import documents of varying complexity related to solid tumors for testing. Check that chunked content in the knowledge base maintains contextual coherence and avoids splitting critical information.
- Simulate high-concurrency queries. Observe the knowledge base's response time and the stability of citation returns to ensure reliable traceability information under load.
