Data Characteristics in this Domain
Target discovery data primarily originates from public biomedical databases (e.g., PubMed, Gene Ontology, KEGG), clinical trial registries (e.g., ClinicalTrials.gov), and experimental data reports like high-throughput sequencing and proteomics. These data sources have varying update frequencies; some databases update weekly or monthly, while experimental reports release irregularly based on research progress. Documents typically exist as research papers, patents, experimental reports, gene sequence files, and protein structure files. Fields include gene/protein identifiers (e.g., Entrez Gene ID, UniProt Accession), disease names (e.g., ICD-10 Code), drug names, mechanisms of action, clinical phases, experimental conditions, and statistical P-values. Units are diverse, covering molecular weight (kDa), concentration (nM), activity (IC50), and expression levels (FPKM).
Constraints Imposed by these Characteristics on Citation and Traceability
The heterogeneity and varied update frequencies of target discovery data sources require FastGPT to support multi-source data import and incremental update mechanisms during knowledge base construction. For example, processing journal articles involves handling multiple formats like PDF and XML, extracting key information. The diversity and specialized nature of fields mean traditional keyword matching may be insufficient for traceability. This necessitates more complex semantic understanding and entity recognition capabilities to accurately link a Gene ID with its IC50 value in a specific disease. Furthermore, statistical P-values and similar data in experimental reports are crucial for traceability accuracy; the system must identify and cite these key numerical values. Frequent data updates also demand timely citation sources, ensuring referenced literature or data is the latest version.
Configuration Guidelines
| Configuration Item | Recommended Value | Rationale for Recommendation |
|---|---|---|
Chunk size (Segment Length) | 500-800 characters (characters) | Accommodates paragraph lengths in research papers and experimental reports, balancing contextual completeness and retrieval efficiency. |
Recall count (Recall Count) | 10-15 entries (items) | Considering the complex associations involved in target discovery, increasing the recall count helps cover more potentially relevant information. |
Similarity threshold (Similarity Threshold) | 0.75-0.85 | Ensures recalled results are highly relevant to the query, avoiding the introduction of excessive noise data. |
Rerank result count (Rerank Return Count) | 5-8 entries (items) | After high recall, reranking focuses on the most relevant and authoritative citation sources. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds (seconds) | Handles parsing large experimental reports or complex literature, preventing import failures due to timeouts. |
Knowledge Base Citation Limit (Knowledge Base Citation Limit) | 900 | Addresses the large volume of knowledge and rapid literature updates in the target discovery field, ensuring sufficient capacity. |
Common Pitfalls
- Symptom: After importing a large number of PDF documents into the knowledge base, some document content is missing or formatted incorrectly. Reason: The document parser has insufficient compatibility with certain complex layouts or scanned PDFs, leading to incomplete content extraction.
- Symptom: A query for a specific gene fails to include the gene's activity data from the latest research in the returned citation sources. Reason: The knowledge base did not synchronize updated public database information in time, or the incremental update mechanism was improperly configured.
- Symptom: When processing user queries about drug mechanisms of action, the system returns citation sources that do not match the user-input
ICD-10 Code. Reason: The entity recognition model has insufficient capability to identify synonyms or abbreviations for medical terms, failing to correctly link query terms withICD-10 Codein the knowledge base.
Validation Steps
- Select a batch of typical literature containing gene identifiers, disease names, and key experimental data. After importing into the knowledge base, query these key pieces of information. Verify if the returned citation sources accurately point to the corresponding data points and paragraphs in the original text.
- Simulate user queries, inputting target information from the latest research. Check if the system recalls and cites the most recently updated literature or database entries.
- For different document types (e.g., plain text, PDF, XML), observe if parsing failure error logs appear during knowledge base construction. Check the completeness of the content after import.
