    This paper describes some practical and theoretical foundations of Structured Document Logic (SDL), which is a logical methodology for analyzing properties of Web documents, like XML or HTML. SDL can make benefits in searching of HTML pages, or in defining filters for web documents. Both syntax and semantics of SDL are described, and an efficient evaluation algorithm is also introduced

    The objective of this research programme is to contribute to the establishment of the emerging science of Formal Ontology in Information Systems via a collaborative project involving researchers from a range of disciplines including philosophy, logic, computer science, linguistics, and the medical sciences. The re­searchers will work together on the construction of a unified formal ontology, which means: a general framework for the construction of ontological theories in specific domains. The framework will be constructed using the axiomatic-deductive method of modern formal ontology. It will be tested via a series of applications relating to on-going work in Leipzig on medical taxonomies and data dictionaries in the context of clinical trials. This will lead to the production of a domain-specific ontology which is designed to serve as a basis for applications in the medical field
