英文摘要:
      Objective To compare the subject indexing and retrieval functions between PubMed and Embase. Methods The PubMed and Embase were comparatively analyzed in terms of their development history, structure system, subject indexing and retrieval. Results The MeSH had a long, mature, stable history, and a larger application scope. The structure of MeSH was similar to that of Emtree. The volume of Emtree was larger than that of MeSH while the subject indexing in PubMed was better than that in Embase. Conclusion PubMed and Embase have their own characteristics. PubMed is easier to use than Embase while Embase attaches greater importance to its visualized operation and variability in processing its retrieval results than PubMed does.
