- W2360624123 abstract "The traditional way of information retrieval is to use the Keywords to express the information requirement.But it is hard to faithfully express the user's retrieval purpose.So this paper brings forward an information retrieval mechanism based on the domain ontology.We use the domain ontology to comprehend and extend the original keywords inputted by the user,then assign a weighted value to each keyword based on the concept-correlation value of the domain ontology and put it into use of the later information retrieval work.The experiment results prove that this way can obviously improve the recall ratio while basically maintaining the precision ratio." @default.
