A new rule-based spectra interpretation system named SpecInt is described. Its internal information representation and the simultaneous use of several spectroscopic methods allow one to achieve both high reliability and good performance. For small-and medium-sized molecules, SpecInt is capable of automatically reducing the solution space to under 3%.
The consequences of incomplete spectra interpretation and the
dependence of the efficiency of demanded
and forbidden fragments on their structural characteristics are
investigated. It is shown that the performance
of a rule-based system strongly depends on the type of structure
generator applied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
