If users are expected to depend on answers from applications and services on the web, they need to have methods for asking for information that will increase their understanding and their trust in the answers. One way of increasing a user’s understanding and trust is to provide a summarized or detailed description of how the answer was obtained. This process would typically depend on some kind ...

With the recent growth of Linked Data on the Web there is an increased need for knowledge engineers to find ontologies to describe their data. Only limited work exists that addresses the problem of searching and ranking ontologies based on a given query term. In this paper we introduce DWRank, a two-staged bi-directional graph walk ranking algorithm for concepts in ontologies. DWRank characteri...

This study examined the role of parenting styles and parental warmth in moderating relations between exposure to political life events and mental health symptoms among 277 Israeli adolescents aged 12-14 and their parents, who had been exposed to protracted periods of war, missile bombardments, and terrorism.

Sir William Osler is celebrated today not only for his contributions to the advancement of medical education, but also for the humanism he brought to the practice of medicine. He was a doctor whose bedside skills and manners were emulated, and can legitimately be called an infectious diseases specialist. Nonetheless, he was also a humanist in the broader sense of the term, a student of human af...

Many of the existing approaches for program comprehension rely on the linguistic information found in source code, such as identifier names and comments. Semantic clustering is one such technique for modularization of the system that relies on the informal semantics of the program, encoded in the vocabulary used in the source code. Treating the source code as a collection of tokens loses the se...

No results found” is a misleading phrase because it masquerades as a definitive answer; in reality, the library being searched may contain content that matches a user’s query. This research seeks to understand the effect of null result sets on search behavior and on the perception of contents in digital libraries. Concepts utilized by social computing frameworks and current-generation eCommerce...

As has been frequently observed in the literature, there is a strong connection between a derived data item’s provenance and its authoritativeness, utility, relevance, or probability. A standard way of obtaining a score for a derived tuple is by first assigning scores to the “base” tuples from which it is derived — then using the semantics of the query and the score measure to derive a value fo...

BACKGROUND Computer decision support systems have been proposed as a suitable method to enable primary care practitioners to manage familial cancer and advise about other developments in clinical genetics. OBJECTIVE To investigate GPs' preferences, attitudes and intentions regarding the use of Genetic Risk Assessment on the Internet and Decision Support (GRAIDS) in clinical practice. METHOD...

At the heart of many effective approaches to the core information retrieval problem— identifying relevant content—lies the following three-fold strategy: obtaining contentbased matches, inferring additional ranking criteria and constraints, and combining all of the above so as to arrive at a single ranking of retrieval units. Over the years, many models have been proposed for content-based matc...
