Semio Corporation announced new versions of its SemioTagger categorization engine and its Semio Plumtree Integration Module. Enhancements to SemioTagger include support for Oracle databases and the ability to crawl data stored by Documentum, performance improvements and additional source file support. Significant new features in the Semio Plumtree Integration Module include relevance ranking and crawl-time indexing. The new Oracle database support, in addition to existing Microsoft SQL Server support, means that XML metadata generated by Tagger can be automatically loaded into most databases in either Unix or Windows environments. Documentum support has also been expanded in SemioTagger for Unix, enabling categorization of information for Documentum in both environments. These features, along with many performance enhancements, are available immediately in version 4.2 of SemioTagger.
