Data Characteristics
Lead optimization data comes from high-throughput screening (HTS) reports, computational chemistry simulation results, pharmacokinetic (ADME) prediction reports, and preliminary in vitro or in vivo experimental data. This data is structured (e.g., compound library data, activity screening results) and semi-structured (e.g., experimental logs, researcher notes, methodology documents). Update frequency depends on research progress, typically project-driven, with incremental updates after each experiment or simulation batch. Document structures vary, including CSV, JSON, PDF reports, and Word or Markdown experimental protocols and results. Key fields include compound SMILES strings, IC50 values (in nM or µM), LogP, molecular weight, target affinity, and cytotoxicity data.
Constraints on Citation and Traceability
The diversity and update rhythm of lead optimization data impose specific requirements on citation and traceability. Structured data requires precise field matching to ensure numerical data like IC50 is correctly identified and aggregated during citation. Semi-structured data needs stronger semantic understanding to extract key information from free text. Project-driven incremental updates mean the knowledge base must support efficient partial training and version management, avoiding full rebuilds with each update. Citing compound SMILES strings requires maintaining their integrity; any truncation can lead to traceability failures. Potential contradictions or uncertainties between different experimental data demand that citation results clearly show the original source, assisting engineers in their judgment.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Chunk size (Segment Length) | 500–800 characters (characters) | Balances context completeness and retrieval efficiency, accommodating paragraph lengths in experimental reports. |
Recall count (Recall Count) | Top 8 entries (top 8) | Addresses multi-source data integration needs, increasing initial recall coverage. |
Similarity threshold (Similarity Threshold) | 0.75 | Ensures recalled results are highly relevant to the query intent, reducing noise. |
Rerank result count (Reranked Return Count) | Top 3 entries (top 3) | Focuses on the most relevant information, improving the accuracy and refinement of the final output. |
maxContext | 4096 tokens | Accommodates complex contexts containing multiple experimental data points and method descriptions. |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds (seconds) | Handles longer parsing times for large experimental reports or computational results files. |
Common Pitfalls
- After uploading many files, some files show abnormal training status. This can be due to individual file sizes exceeding the
UPLOAD_FILE_MAX_SIZElimit or file parsing timeouts. - The AI chat component occasionally omits key numerical values (e.g.,
IC50) when citing lead compound data. This usually happens when the knowledge base segmentation strategy is too aggressive, separating the value from its descriptive context, leading to incomplete context during recall. - In variable reference mode, the large model's
temperatureparameter cannot be adjusted. This can limit the model's flexibility in expressing uncertainty in data (e.g., prediction results) when generating responses, preventing adjustment of the generated content's conservative or divergent nature based on requirements.
Verification Steps
- Select representative queries. Check if the returned citations include key compound IDs (
compound_id), experimental values, and corresponding experimental conditions. - Upload a PDF report containing known
SMILESstrings,IC50values, and experimental methods. Verify if the model can accurately extract and cite this information. - Conduct multiple simulated conversations. Observe if the model clearly labels the original document name or section when citing data from different sources.
- In the knowledge base management interface, randomly sample the segmentation of trained files. Confirm that key fields and their contexts remain intact.
