  Indexing Initiative > Datasets & Test Collections
This page contains Datasets and Test Collections related to the various research projects and papers associated with the Indexing Initiative project. In some cases, these are the complete Test Collections used including MEDLINE citations and any manually annotated results. In other cases, we provide PMIDs for the MEDLINE citations used in the experiments and it is up to the user to download these either from Entrez/PubMed or our MEDLINE Baseline Repository web sites. The packaging depends on what permissions we have been granted for releasing the data.

Datasets (DS) Logo denoting Dataset Available - Green circle with letter 'd' : Contain the basic components required to replicate a set of experiments. This will at a minimum include lists of PMIDs and may include additional information.

Test Collections (TC) Logo denoting Test Set Available - Blue circle with letter 't' : Contain a full complement of data required to replicate a set of experiments. This will include PMID lists, MEDLINE citations in XML and or ASCII MEDLINE format, annotated results, and detailed explanations of the results.

  • 151 Citation GIA Test Collection Logo denoting Test Set Available - Blue circle with letter 't'
    Test Collection used in our Gene Indexing Assistant (GIA) project. The GIA corpus consists of 151 manually annotated MEDLINE citations, randomly extracted from journals on human genetics with publication dates between 2002 to 2011. Sentences in each abstract were detected and tokenized using MetaMap.

    Please Note: The use of The GIA Test Collection is covered by the MetaMap Terms and Conditions, please review that document prior to downloading the GIA Test Collection.

    All sentences were processed by our Gene Mention Identification module to tag gene mentions, and then corrected manually by a single annotator. Explicit mentions of individual genes or gene products are normalized to the relevant Entrez Gene ID. In cases where an individual gene is indicated, but the annotator was unable to determine which Entrez Gene ID was correct, the ID has been identified as "-1". For compound mentions, the extent of each mention is marked as the information required to identify the gene. For example, for BRCA1/2, two gene mentions would be delineated as "BRCA1" and "BRCA1/2." Proteins that refer to multiple genes, or mentions of protein families, are not annotated.

    The original sentence by sentence annotated file has been converted into a format consistent with the Biocreative format. The format used is as follows:
    pmid|t|entire title here
    pmid|a|entire abstract here
    pmid<tab>offset start<tab>offset start+strlen<tab>1st gene mention<tab>Gene<tab>Entrez Gene ID

  • Word Sense Disambiguation (WSD) Test Collection Logo denoting Test Set Available - Blue circle with letter 't'
    Please Note: The original 1998 WSD Test Collection is considered out of date at this point. We strongly recommend using the more current version of WSD created by Antonio Jimeno-Yepes and Bridget McInnes - MSH WSD Dataset. The MSH WSD Dataset is more current and contains a much larger and richer set of ambiguities.

    The test collection consists of 50 highly frequent ambiguous UMLS concepts from 1998 MEDLINE. Each of the 50 ambiguous cases has 100 ambiguous instances randomly selected from the 1998 MEDLINE citations. For a total of 5,000 instances. We had a total of 11 evaluators of which 8 completed 100% of the 5,000 instances, 1 completed 56%, 1 completed 44%, and the final evaluator completed 12% of the instances. Evaluations were only used when the evaluators completed all 100 instances for a given ambiguity. The following paper describes in more detail the development of the test collection:

    Access to the WSD Test Collection requires an UMLS KS login.


  • 500 PubMed Central Full Text Test Collection Logo denoting Test Set Available - Blue circle with letter 't'
    Test Collection used in our Full Text experiments to date, and reported on in the 2005 AMIA paper, "Semi-Automatic Indexing of Full Text Biomedical Articles, AMIA 2005" (PDF: 100kb). For more detailed information on Indexing Initiative work involving Full Text, please see the section "Full Text Processing.
    • Original PubMed Central XML Format Original PubMed Central XML Format (October 22, 2003) Version   (8 mb)
      This is a tar file containing XML DTD files and a subdirectory "xml" which contains all 500 of the articles in separate *.pxml files.

    • Original PubMed Central ASCII MEDLINE Format Original PubMed Central ASCII MEDLINE Format (March 22, 2005) Version   (1.4 mb)
      This is a text file containing abstracts in ASCII MEDLINE format from PubMed Enrez for 498 of the 500 articles. This file contains the MeSH Indexing used for comparison purposes in the above mentioned paper. Two of the PMIDs in the test collection have PMIDs of "0" and do not have indexing in this file.

    • Pseudo-ASCII MEDLINE Format Pseudo-ASCII MEDLINE Formatted (December 12, 2003) Version   (15.3 mb)
      This is a single file containing all 500 articles put into a pseudo-ASCII MEDLINE format which is required for MTI.

    • Pseudo-ASCII MEDLINE Label Break-out Format Pseudo-ASCII MEDLINE Formatted Label Break-out (February 6, 2004) Version   (15.4 mb)
      This is a single file containing all 500 articles put into a pseudo-ASCII MEDLINE format which is required for MTI. This file differs from the above in that the "important" sections (which might have separate sub-sections) have been separated in the article and a new "citation" associated with the article PMID and label created. For example, "Background", "Methods", "Results", "Discussion", "Conclusions", etc. With the base abstract and title listed separately and first for each article.

      Example (PMID 11884248): PMC file shows <abs><sec><st> <p>Abstract</p></st> <p>Background</p></st>
      is translated to "AB - Abstract | Background | " in the pseudo-ASCII MEDLINE Break-out version as the main section "Abstract" contains a sub-section "Background".

      Example II (PMID 11884248): PMC file shows </abs></fm><bdy><sec><st> <p>Background</p></st>
      is translated to "PMID- 11884248_Background" in the pseudo-ASCII MEDLINE Break-out version as a new section in the article is identified as "Background", so we create a new "citation" using the same PMID and the new section name as the identifier.



  • 200 MEDLINE Citations Test Collection Logo denoting Test Set Available - Blue circle with letter 't'
    Test Collection used in our original experiments, tuning parameters phase, and now used to track improvements to MTI. We have included the original test collection from January 20, 1999 to allow comparison based on the actual data from that time. We have also included an updated version of the Test Collection to allow for more current comparison studies involving the use of PMIDs and current MeSH Indexing.
