In this paper, a restricted domain question answering (QA) system is described. The design architecture of this QA system and the features that allow the adaptation of the QA system to the medical domain are also presented. The advantages of…

Žinių samprata yra sudėtinga, įvairi ir daugiaprasmė. Moksliniu požiūriu žinių prigimtį ir esmę jau keletą dešimtmečių tyrinėja įvairių sričių mokslininkai, tačiau iki šiol nėra sukurtos visuotinai pripažintos žinių potencialo vertinimo metodikos, vartojamos skirtingos sąvokos, nesutariama, kokie veiksniai yra esminiai vertinant…

Conversational interfaces have received much attention as a promising natural communication channel between humans and computers. A typical conversational interface consists of three major systems: speech understanding, dialog management and spoken language generation. In such a conversational interface, speech recognition…

The Embrapa Agricultural Instrumentation Center, one of the thematic centers of the Brazilian Agricultural Research Corporation, is an institution of science and technology in instrumentation. Its purpose is to promote Brazilian agribusiness through the generation, adaptation, and transference of knowledge…

Quand le E-learning a émergé il ya 20 ans, cela consistait simplement en un texte affiché sur un écran d'ordinateur, comme un livre. Avec les changements et les progrès dans la technologie, le E-learning a parcouru un long chemin, maintenant…

This work extends the semantics and implementation of fuzzy prolog presented in [VGM02] in order to include Default Knowledge capability. The new semantic allows non-uniform default assumptions and has Closed World Assumption (CWA) and Open World Assumption (OWA) as particular…

The Knowledge Engineering Suite is an ontology production method, based on relationship networks, for knowledge representation inside specific contexts. The production of these ontologies has three basic steps, since catching the client data, knowledge base creation, and information retrieval and…

Current methods for bipedal walking control include playback of recorded joint motion and the derivation of dynamic equations to map desired forces at the body to the required torques at the joints. Both methods require a significant amount of up-front…

The objective of the experiments described in this thesis is to perform a detailed spectroscopic study of the dynamics on the A and X state surfaces of 13C2H2 in order to further understand the acetylene - vinylidene isomerization process in…

The proper interpretation of measurements from an optical fiber sensor requires a full understanding of its mechanical response to external action and the corresponding change in optical output. To quantify the mechanical behavior it is necessary to know the mechanical…
