We developed a new integration algorithm for autonomous nomenclature databases in the presence of semantic heterogeneity over international computer networks. First, the algorithm requires users to assign priority according to order of belief for each one of the accessible nomenclature databases. Integration is achieved by increasing the kernel database, selected by the algorithm as the one with the highest priority among the databases. Complex problems are included to recognize consistent parts that can be incrementally added to the kernel database in the remainder of the accessible nomenclature databases through the use of tree structures. The algorithm with relational operators, was proposed after considering both structural and cooperative constraints useful in managing single and multiple databases. In addition, we present a nomenclature database system including the useful algorithm. The system is also accessible from remote users through World-Wide Web and is implemented in SQL programming and CGI (Common Gateway Interface) scripts of World-Wide Web. The system can be useful in both integrating and managing biological taxonomy databases over international computer networks.
