Quantitative evaluation of library searching performance

Abstract: A procedure Is descrlbed for the quantltatlve evaluatlon of the performance of a llbrary searchlng system employed for molecular structure elucldatlon. The technlque allows the evaluatlon of any form of spectral representation or any spectral comparison metrlc. The approach Is applicable to any type of spectrometry used for llbrary searchlng (LS) or to comblnatlons of different types of spectra. All comparisons are made relative to a chosen standard of quallty for library searching performance. I t Is assumed … Show more

“…The qualitative evaluation of library searching performance (QELS) (17)(18)(19) was used to evaluate the search performance of the five noise replicates of each of the 20 test spectra (a total of 100 spectra) at each of the 11 S/N levels. The standards used with QELS were generated from library-1842 using the dot product metric.…”

“…Quantitative Evaluation of Library Searching Performance (QELS). A generally applicable quantitative approach to LS performance evaluation has been developed in this laboratory (18). In QELS, the performance of any combination of library spectra representation and comparison metric is compared against the performance of any chosen LS standard.…”

“…e identification of each component in the FTIR spectrum is crucial for accurate quantitative analysis. In the early stage of FTIR spectrum identification, library searching (LS) methods [18] were adopted when the spectral components were single or the absorption peaks rarely overlapped. Lavine et al [19] used pattern recognition methods as the search prefilters for library searching and made the identification more precise and faster.…”

“…The quantitative approach for LS performance evaluation, developed in this laboratory, is described in detail elsewhere. 14 In QELS, the performance of any combination of library spectra representation and comparison metric is compared against an LS standard. In the present case, we employ full-resolution spectra and the Euclidean distance comparison metric as our standard.…”
