Record extraction from data-rich, unstructured, multiplerecord Web documents works well [8], but only if the text for each record can be located and isolated. Although some multiple-record Web documents present records as contiguous, delineated chunks of text (which can thus be located and isolated [9]), many do not. When some values of textual records are factored out, are split unnaturally ac...

This work compares two alternative methods for record linkage: distance based and probabilistic record linkage. It compares the performance of both approaches when data is categorical. To that end, a distance over ordinal and nominal scales is defined. The paper shows that, for categorical data, distance-based and probabilistic-based record linkage lead to similar results in relation to the num...
