SYSTEM AND METHOD FOR AUTOMATIC WRAPPER INDUCTION BY APPLYING FILTERS

摘要

Information from a plurality of domains is automatically extracted according to an iterative application of rules. A first rule is generated based on a target string. The first rule comprises at least one filter. A domain of interest is identified and a training set is generated using the target string and at least one document in the domain of interest. The first rule is applied to each document in the training set to obtain a first of target results. The first set of target results are compared to desired set of target results. Based on the comparison, a second rule may is created and applied to the training set to yield an improved second set of target results.
