====== Mining biomedical literature ======
 

Mining biomedical [[literature]] involves extracting, analyzing, and synthesizing information from vast amounts of scientific texts, including research [[paper]]s, [[clinical trial]]s, [[patent]]s, and [[medical report]]s. This process is crucial for staying updated with [[advancement]]s, identifying [[trend]]s, and supporting [[evidence-based medicine]].

===== Key Aspects of Mining Biomedical Literature =====

1. **Text Processing & Data Extraction**
   - **[[Natural Language Processing]] (NLP):** Techniques, like [[Named Entity Recognition]] (NER), [[tokenization]], and part-of-speech tagging help, extract key biomedical entities (genes, proteins, diseases, drugs, etc.).
   - **Ontology-Based Extraction:** Utilizing standardized ontologies such as [[MeSH]], [[UMLS]], and SNOMED CT improves accuracy in retrieving relevant biomedical [[term]]s.

2. **Literature Databases**
   - **[[PubMed]]/[[MEDLINE]]:** The most widely used repository of biomedical articles.
   - **[[Google Scholar]], [[Embase]], [[Scopus]]:** Additional sources for comprehensive searches.
   - **[[ClinicalTrials.gov]]:** For mining ongoing and past clinical trials.

3. **Machine Learning & AI in Literature Mining**
   - **Topic Modeling (LDA, BERT-based models):** Identifies emerging research topics.
   - **Relation Extraction:** Finds interactions between biological entities.
   - **[[Summarization]] & Question Answering:** AI-driven tools like ChatGPT assist in summarizing key findings.

4. **Applications**
   - **[[Drug Discovery]]:** Identifying potential drug targets and repurposing existing drugs.
   - **[[Systematic Review]]s & Meta-Analysis:** Automating literature review processes.
   - **[[Precision Medicine]]:** Analyzing literature for patient-specific treatment recommendations.

5. **Challenges**
   - **Volume & Complexity:** Handling large [[dataset]]s with domain-specific language.
   - **[[Ambiguity]] in Biomedical Terminology:** Resolving synonym issues.
   - **Access [[Restriction]]s:** Many journals require subscriptions.
