Data Characteristics in Target Discovery
Target discovery data comes from diverse sources. These include public literature, patent databases, clinical trial reports, genomics and proteomics data, high-throughput screening results, and internal experimental data. Data update frequencies vary. Public literature and patent databases typically update monthly or quarterly. Internal experimental data may be generated in real-time. Document structures are complex. They include unstructured research papers and experimental records, semi-structured compound activity data and gene expression profiles, and structured database records. Fields and units are highly specialized. Examples include compound IC50 values (nanomolar/nM), gene expression levels (FPKM/TPM), and protein interaction affinity (Kd values). These involve numerous biomolecular identifiers, disease ontology terms, and experimental condition descriptions.
Constraints Imposed by Data Characteristics on Model Integration and Configuration
The complexity of target discovery data places specific demands on model integration and configuration. Pre-processing unstructured documents requires robust text extraction and entity recognition capabilities. These capabilities extract key information like targets, diseases, compounds, and mechanisms of action from vast amounts of literature. Integrating multi-source heterogeneous data requires models to handle different formats and update frequencies, then effectively merge these data streams. Specialized fields and units require models to possess domain knowledge. Models must understand biomedical terminology, accurately interpret IC50 values and their units, and avoid confusing values with different units. This directly influences the choice of vectorization models, which need good domain adaptability. The large volume and specialized nature of the data also require fine-tuned adjustments to knowledge base chunking granularity, recall strategies, and reranking logic. This ensures the accuracy and relevance of query results.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Chunk Size) | 800–1200 characters | Balances context completeness with vector model processing efficiency |
Chunk overlap (Chunk Overlap) | 100–200 characters | Ensures continuity of information across chunks and captures key entity relationships |
embeddingModel | bge-large-zh | Better understanding of biomedical terminology, supports Chinese literature processing |
maxContext | 4096 tokens | Covers key summaries and experimental results of most research papers |
Recall count (Recall Count) | 10–15 items | Balances recall breadth with subsequent reranking load |
Similarity threshold (Similarity Threshold) | Calibrate based on actual measurements | Optimizes recall precision for specific datasets and query types |
Common Pitfalls
- Knowledge base query results are empty. The
embeddingModelmay not correctly identify biomolecular entities and specialized terms, leading to poor vectorization quality and failed query matches. - Model-returned target information is inaccurate or lacks critical values. The text extractor may have failed to parse table data from PDFs or images during file upload, resulting in original data loss.
- After integrating a domain-specific model, the API test shows an error
KokoroModel' object has no attribute 'mode'. This typically indicates an incompatible model interface protocol or incorrect API key configuration.
Validation Steps
- Upload a batch of PDF literature and structured experimental data containing various target information. Check if compound names, gene IDs, mechanisms of action, and key values are correctly extracted into the knowledge base.
- Conduct multi-turn dialogue tests for typical target discovery questions (e.g., "Find CDK inhibitors related to tumor immunity"). Evaluate if the model can recall relevant literature snippets and provide accurate answers. Check the
Similarity thresholddistribution of the recall results. - Compare model output with human-annotated reference answers. Evaluate the accuracy and recall rate of key entity identification (e.g., targets, diseases, drugs). Adjust
Chunk sizeandChunk overlapparameters based on the results.
