Our long-term goal is to build a query answering system that can answer questions on a wide variety of topics and explain the answers. In such a situation, a designer faces the challenge of how to specify the KR&R requirements that are needed to answer questions. In this paper, we introduce a categorization of KR&R methods, and apply it to specifying the requirements for answering questions in ...

The Semantic Web (SW) was originally positioned as a combination of Knowledge Representation (KR) and the Web. However, most applications that use SW data today lean more towards the Information Retrieval spectrum. The reason for this is that traditional KR systems are designed to work with datasets that are small, curated, homogeneous, and application-specific. However, the SW is large-scale, ...

Think of elementary linear logic as an idealized functional programming language with a severe typing mechanism. Definition by recursion is, of course, forbidden, but some sort of iteration still is possible and the purpose of this paper is to show that enough computing power remains so that elementary recursive functions can be implemented. Actually, the whole paper can be considered an exerci...

A novel scheme of coUinear fast beam laser spectroscopy for the detection of the long lived rare isotope *^Kr by observing the optical hyperfme structure spectrum is presented. The technique utilizes cascade two-step excitation to pump metastable krypton atoms to a high-lying Rydberg level. The present work on krypton was motivated by the fact that *̂ Kr is a major tracer gas for exploring the r...

Paradox is one of the literary techniques in the poetry of the Safavid poets. Hazin-e Lahiji, like so many other poets of that age, employed this technique in his pursuit and showed that "unfamiliar meaning". Paradox is used in the poetry of Hazin-e Lahiji for the purpose of defamiliarization and exoticism. The poet in order to create new implications and subtle and insightful points and also t...

The Shining Hospital is situated in the town of Pokhara in the Himalayan foothills, at an altitude of 1000 metres. To the north lie the desolate peaks of the Annapurna range, while in other directions numerous small villages are scattered among the hills. The people of these agrarian communities, together with the traders of Pokhara Bazaar, make up the hospital's catchment population of about o...

We present the Kr-Kr derived exposure ages for H-chondrites which were recently investigated for their Cl-Ar ages. After demonstrating that our Kr-Kr ages are reliable and reproducible we find hints that Kr/Kr and Kr/Kr might depend on the relative concentrations on the target elements Rb, Sr, Y, Zr, and Nb. In addition, the Kr-Kr ages for the large L-chondrite Gold Basin indicate that the Kr-K...
