Steps Toward Automatic Theory Formation

This paper describes a theory formation system which can discover a p a r t i a l axiomization of a data base represented as extensional ly defined binary r e l a t i o n s . The system f i r s t discovers a l l possible in tens ional d e f i n i t i o n s of each binary re la t i on in terms of the others. It then determines a minimal set of these re la t ions from which the others can be def ...

Macrocyclic drugs and synthetic methodologies toward macrocycles.

Macrocyclic scaffolds are commonly found in bioactive natural products and pharmaceutical molecules. So far, a large number of macrocyclic natural products have been isolated and synthesized. The construction of macrocycles is generally considered as a crucial and challenging step in the synthesis of macrocyclic natural products. Over the last several decades, numerous efforts have been underta...

Half-steps toward LMNL

Overlap in markup occurs where some markup structures do not nest, such as where the sentence and phrase boundaries of a poem and the metrical line structure describe different hierarchies. LMNL (Layered Markup and Annotation Language) is a model for representing textual data, designed to recognize and account for layer separation and markup overlap. LMNL is specified as a data model, not as a ...
