JATSdecoder efficiently extracts data from PubMed Central XML files, enabling text mining of scientific literature. However, inconsistencies in metadata tags and author identification present challenges for researchers.
Area of Science:
- Biomedical and Health Sciences
- Computational Biology
- Bibliometrics
Background:
- PubMed Central (PMC) hosts over 3.2 million open-access biology, medical, and health science articles.
- NISO-JATS (Journal Article Tag Suite) is a standard for coding XML documents in scientific publishing.
- Text mining scientific literature requires reliable data extraction tools.
Purpose of the Study:
- To evaluate the utility of JATSdecoder for processing the PubMed Central (PMC) document collection.
- To analyze the consistency and extraction capabilities of NISO-JATS tags within the PMC corpus.
- To identify possibilities and limitations for text mining scientific literature using JATSdecoder.
Main Methods:
- Processing a large corpus of PMC documents using the JATSdecoder toolbox.
- Analyzing the development and consistency of extracted NISO-JATS tags over time.
- Examining specific metadata elements, including author identification and date stamps.
Main Results:
- JATSdecoder reliably extracts key metadata and text elements from NISO-JATS XML files.
- NISO-JATS tags are generally used consistently, facilitating metadata and text extraction.
- Inconsistencies were noted in date stamps and author identification codes, particularly for authors with common or Asian names.
- Subject and keyword tags show significant inconsistency, requiring careful selection criteria for subset analysis.
Conclusions:
- JATSdecoder is a valuable tool for text mining PMC's open-access scientific literature.
- Researchers can leverage JATSdecoder for new monitoring and text mining approaches.
- Careful application of inclusion/exclusion criteria based on NISO-JATS tags is crucial for accurate data subset selection.
