Thus, for the per-category precision, the list of terms used to generate the denominator in the metric are not necessarily mutually exclusive across categories.
No per-category precision is reported for PHI in the "Undefined" category, since these PHIs are extremely infrequent or absent from the gold standard corpus.
The per-category precision for category i is defined as the number of true positives in category i divided by all PHIs located by the algorithm using the filter specific to category i.
The overall F-value on the matched categories was 95.3% (precision 98.1%, recall 92.8%), higher than 64.7% F-value on the discrepant categories (precision 53.4%, recall 81.8%).> -wrap-foot> P indicates precision; R recall; F F-value.
The experimental results are reported under two main performance measurement categories, precision-recall curves and classification accuracies.
As expected, Table 3 illustrates that the best results are achieved with partial matches and one unique PHI category (95% precision, 78% recall and 67% F2-measure), decreasing dramatically when considering fully-contained matches (58% precision, 36% recall, 37% F2-measure).
From 2004 to 2010, 3.1% of participants changed exposure category, a precision we consider acceptable and which is unlikely to bias our results appreciably.
The performance of Textpresso on the evaluation dataset at the sentence level is comparable to that presented in the internal benchmarking for Category 4 (precision and recall 80.1% and 30.0%, respectively, compare sentence level in Benchmark Tables 1 and 4).
More specifically, the method identified 39 high‐precision categories reaching precision at 40 values equal or larger than 0.75.
Although that sounds as if it would hurt (and tongues bleed, right?), the scraper would still face stiff competition from another haunting entrant in the personal hygiene category, the Flowbee Precision Haircutting System.
Disruption will involve pushing more of medicine into the precision category, then automating that care to make it better and cheaper.
