PiQASso is a Question Answering system based on a combination of modern IR techniques and a series of semantic filters for selecting paragraphs containing a justifiable answer. Semantic filtering is based on several NLP tools, including a dependency-based parser, a POS tagger, a NE tagger and a lexical database. Semantic analysis of questions is performed in order to extract keywords used in re...

OBJECTIVE To determine which drug references Utah pharmacists use most frequently. To determine which types of drug information questions are most commonly asked, and whether Utah pharmacists have access to adequate references to respond to these questions. METHODS A 19-question survey was created using Qualtrics, LLC (Provo, Utah) software. An electronic survey link was sent to 1,431 pharmac...

Logical reasoning skills are important for a successful mathematical learning and in students’ future career. These skills are essential for a primary school teacher, because they need to explain solving methods and solutions to their pupils. In this research we studied pre-service primary school teachers’ logical reasoning skills. The results show that only one third of the students gave an ar...

In a recent paper [BBL02] a propositional logic called Qualitative Choice Logic ( ) was introduced. The logic contains a new connective representing ordered disjunction. Intuitively, stands for: if possible , but if is impossible then (at least) . This connective allows context dependent preferences to be represented in a simple and elegant fashion. In this paper we show how to combine ideas un...

Deciphering the functioning of the so-called biological networks is one of the central tasks in systems biology. In particular, signal transduction networks are crucial for the understanding of the cellular response to external and internal perturbations. Notably, such networks are involved in biomedical processes and their control has a crucial impact on drug target identification and diagnosi...

This paper aims to apply modal logics arising from partitionistic structures to the logic of questions and answers. Taking it for granted that a partition of possible worlds serves as a representation of a context, the idea of multi-contextual situation motivates the proposal of partitionistic structures. Logical properties of answers are represented by modal operators on such structures. 1 Mot...

[1] Since 2009 the Lunar Reconnaissance Orbiter (LRO) has made comprehensive measurements of the Moon and its environment. The seven LRO instruments use a variety of primarily remote sensing techniques to obtain a unique set of observations. The analyses of the LRO data sets have overturned previous beliefs and deepened our appreciation of the complex nature of our nearest neighbor. This introd...
