These features are extracted in this case from HL7-CDA EHRs, but other XML-based standards for EHRs, such as new versions of the HL7-CDA, will provide new possibilities to identify relevant retrieval terms within more structured documents.
Textwords within the validated search filter are already known to be highly effective title/abstract retrieval terms, having been identified as such during the clinician review, frequency analysis, testing, and validation stages of filter development.
Otherwise, the memory performance data depicted in Table 3 leads us to suggest that the null effect we found during the long-term retrieval condition is probably due to higher forgetting rates in the LHG during the sham condition.
In addition, we evaluate the four models of information retrieval in terms of complexity and applicability.
Adding formal definitions to MedDRA would allow retrieval of terms according to a case definition that may correspond to novel categories that are not currently available in the terminology.
The regions differed in their ability to discriminate species, and in ease of retrieval, in terms of amplification and sequencing success.
Second, the high temporal resolution of EEG allows a fine-grained characterization of concept retrieval in terms of the electrophysiological patterns that make decoding possible.
[The standard ROC terminology refers to 'true positives' and 'false positives', but in information retrieval, the terms 'relevant' and 'irrelevant' are pertinent. Unlike some authors (Hand, 2009), we view information retrieval as a problem in ranking, not a problem in classification.] Let the total number of irrelevant records be F.
The terms "guideline", "practice guideline", and "recommendation" produced the highest number of relevant retrievals (CPG term + "back pain" in Table 1), and were therefore defined as the three CPG terms to be used as the first term of the GLAD search strategy.
In addition, a spatio-temporal assessment of residuals has been performed to evaluate the accuracy of retrievals in terms of daily and seasonal variation, land cover, landscape heterogeneity and topography.
