    Abstract
    Dow Jones Interactive Publishing has developed a sophisticated automatic knowledge indexing system that will allow searchers of the Dow Jones News / Retrieval service to get highly targeted results from a search in the service's Publications Library. Instead of relying on a thesaurus of company names, the new system uses a combination of that basic algorithm plus unique rules based on the editorial styles of individual publications in the Library. Dow Jones have also announced its acceptance of the definitions of 'selected full text' and 'full text' from Bibliodata's Fulltext Sources Online directory

    Abstract
    Explores the potential of text analysis as a tool in full text search and design improvement. Reports on a trial analysis performed in the domain of family history. The findings offered insights into possible gains and losses in using one search or design strategy versus another and strong evidence was provided to the potential of text analysis. Makes search and design recommendation
