In this paper we report employing frame-based system as the basis to build up a ontology-based portal. The basic idea is to transform the ontology schema and instances collected from various digital library sites using the semantics of the frame-based system. The service programs written using the frame-based reasoning formalism thus can make use the knowledge.

We propose a novel semantics for logic programs with negation by viewing the application of a clause in a derivation as an action in the situation calculus. Program clauses are then identiied with situation calculus effect axioms as they are understood in axiomatic theories of actions. We then solve the frame problem for these eeect axioms using a recent approach of Reiter 21], and identify the...

Frame semantics is a theory of linguistic meanings, and is considered to be a useful framework for shallow semantic analysis of natural language. FrameNet, which is based on frame semantics, is a popular lexical semantic resource. In addition to providing a set of core semantic frames and their frame elements, FrameNet also provides relations between those frames (hence providing a network of f...

Введение. Современные исследования терминологий и терминосистем все чаще проводятся в аспекте когнитивного терминоведения. Популярность набирают исследования, посвященные изучению семантики термина рамках терминоведения.Цель работы состоит построении фреймовых моделей предметной области «Строительные технологии», выявлении основных когнитивных категорий подкатегорий, репрезентированных данными ...
