| Abstract: |
A drawback of the current document representation scheme in the ADS abstract service is its heterogeneous subject indexing. Several related but inconsistent indexing languages are represented in ADS. A method of reconciling some indexing inconsistencies is described. Using lexical similarity alone, one out of six ADS descriptors can be automatically mapped to some other descriptor. Analysis of postings data can direct administrators to those mergings it is most important to check for errors. |
