USI: a fast and accurate approach for conceptual document annotation

BMC Bioinformatics

Table 1 F-score, semantic score and processing time for different methods with k =20

Method	F-score	Semantic score	Processing time (s)
PMRA* + MetaMap + Clustering (MTI) [12]	0.398	0.68	N/A
PMRA* + LTR [18]	0.467	0.768	0.169
PMRA* + algorithm implemented in Equation 5	0.474	0.785	0.791
PMRA* + USI	0.474	0.785	0.015
PMRA* + USI_filter	0.521	0.776	0.003
PMRA* + USI + map	0.509	0.807	0.014
PMRA* + USI_filter + map	0.546	0.802	0.004

Note that PMRA* is never taken into account for the processing time since it has already been computed in the benchmark dataset. USI running times were measured on a 2.7Ghz microprocessor and 16Go of RAM Linux machine, whereas LTR running times, kindly provided by Huang et al., were measured on a somewhat comparable configuration but on a different machine.
