The SciQA Scientific Question Answering Benchmark for Scholarly Knowledge.

Knowledge graphs have gained increasing popularity in the last decade in science and technology. However, knowledge graphs are currently relatively simple to moderate semantic structures that are mainly a collection of factual statements. Question answering (QA) benchmarks and systems were so far mainly geared towards encyclopedic knowledge graphs such as DBpedia and Wikidata. We present SciQA a scientific QA benchmark for scholarly knowledge. The benchmark leverages the Open Research Knowledge Graph (ORKG) which includes almost 170,000 resources describing research contributions of almost 15,000 scholarly articles from 709 research fields. Following a bottom-up methodology, we first manually developed a set of 100 complex questions that can be answered using this knowledge graph. Furthermore, we devised eight question templates with which we automatically generated further 2465 questions, that can also be answered with the ORKG. The questions cover a range of research fields and question types and are translated into corresponding SPARQL queries over the ORKG. Based on two preliminary evaluations, we show that the resulting SciQA benchmark represents a challenging task for next-generation QA systems. This task is part of the open competitions at the 22nd International Semantic Web Conference 2023 as the Scholarly Question Answering over Linked Data (QALD) Challenge.

Improved objective Bayesian estimator for a PLP model hierarchically represented subject to competing risks under minimal repair regime.

In this paper, we propose a hierarchical statistical model for a single repairable system subject to several failure modes (competing risks). The paper describes how complex engineered systems may be modelled hierarchically by use of Bayesian methods. It is also assumed that repairs are minimal and each failure mode has a power-law intensity. Our proposed model generalizes another one already presented in the literature and continues the study initiated by us in another published paper. Some properties of the new model are discussed. We conduct statistical inference under an objective Bayesian framework. A simulation study is carried out to investigate the efficiency of the proposed methods. Finally, our methodology is illustrated by two practical situations currently addressed in a project under development arising from a partnership between Petrobras and six research institutes.

Study and analysis of information technology in dentistry in Latin American countries.

Dentistry increasingly uses Information and Communication Technology (ICT), which has impact on teaching, research, the profession and dental care in general. However, there is a lack of valid information on ICT resources and use in Latin America. This was a descriptive, cross-sectional, multi-center, interdisciplinary study, the aim of which was to conduct a survey on how extensively ICT is used in Dentistry in Latin American countries by enquiring into two primary components: 1) use of ICT in student training and 2) use of ICT by professionals in consulting rooms and services. Two questionnaires on ICT were prepared: one for teachers/researchers and another for students/professionals. We received 94 answers from teachers/researchers at universities in the region providing information on ICT resources for teaching (type and implementation) and 221 answers from professionals (personal use and use in healthcare). Data are presented as absolute relative frequencies and analyzed quantitatively as percentages. RESULTS: 1) Teachers highlight ICT as an instrument for development, democratization and fairness in access to knowledge for higher education. 2) ICT supports collaborative learning and generates other innovative resources (e.g. simulators). 3) Innovations in telemedicine and experiences with electronic clinical history were identified in Brazil, Uruguay and Colombia. These results are a basis upon which to reach a consensus regarding a set of ICT indicators which are comparable at regional level and serve as input to unify the design and implementation of ICTs experiences in both teaching and dental care in Latin America.

La Odontología utiliza en forma creciente las Tecnologías de la Información y la Comunicación (TIC) impactando en la enseñanza, la investigación, la profesión y la atención odontológica en general. Sin embargo, no se cuenta con información válida sobre los recursos e utilización de las TIC en latinoamérica. La investigación representó un estudio descriptivo, de corte transversal, multicéntrico e interdisciplinario, cuyo objetivo fue realizar un relevamiento del grado de informatización en Odontología en países latinoamericanos indagando dos componentes principales en el empleo de las TIC: 1) en la formación de estudiantes y 2) por parte de los profesionales en consultorios y servicios. Se realizaron cuestionarios a referentes TIC: uno para docentes/investigadores y otro para estudiantes/profesionales. Se recibieron 94 respuestas de docentes/investigadores de universidades de la región dando cuenta de los recursos TIC para la enseñanza (tipo e implementación) y 221 de profesionales (personal y en la asistencia clínica). Los datos recogidos fueron analizados cuantitativamente con tabulación en porcentaje y se presentan en frecuencia relativa absoluta. Resultados: 1) Los docentes enfatizan a las TIC como instrumento de desarrollo, democra tiza ción y equidad en el acceso al conocimiento en educación superior. 2) Las TIC apoyan el aprendizaje colaborativo y generan otros recursos innovadores (ej: simuladores). 3) Se identificaron innovaciones en telemedicina y experiencias con historia clínica electrónica en Brasil, Uruguay y Colombia. Los resultados constituyen una base para consensuar un conjunto de indicadores TIC comparables a nivel regional y sirven como insumo para unificar el diseño e implementación de las experiencias TIC tanto en enseñanza como en la asistencia odontológica en Latinoamérica.

Communication, technology and ageing: elderly, senior citizen groups and interaction process in the information age / Comunicação, tecnologia e envelhecimento: idosos, grupos de terceira idade e processo de interação na era da informação

Um ambiente computacional mudará a natureza da atividade interacionista se contemplar as mudanças que estão ocorrendo nos métodos de comunicação, pois deve favorecer o trabalho cooperativo. Para desenvolver ferramentas que viabilizem a construção do conhecimento por meio da interação é preciso conhecer os aspectos biopsicossociais e entender o potencial libertador dos processos comunicativos que se estabelecem quando os sujeitos interagem mediados pela tecnologia. Partindo de uma concepção sócio-histórica de interação social, procuramos preencher um espaço de pesquisa em relação à ação comunicativa e à significação das representações sociais sobre as tecnologias de comunicação e informação. Analisamos a tríade comunicação, tecnologia e envelhecimento, objetos de natureza distinta que advêm quando se ponderam questões que envolvem pessoas idosas num contexto biopsicossocial. Buscamos conhecer as representações simbólicas em relação às tecnologias e analisar os sentimentos desencadeados e o significado das experiências vividas com o uso desses dispositivos. Analisamos os processos de apropriação e significação das tecnologias com um grupo de idosos matriculados em oficias de informática do município de Passo Fundo - RS. A pesquisa é um estudo transversal de cunho analítico e populacional. Para analisar os dados utilizamos análise de variância, teste qui-quadrado, análise fatorial e análise de conglomerado em um nível de significância de 5 por cento (p ≤ 0,05). Os resultados revelam que os idosos participam das oficinas com a finalidade de maximizar os processos de convívio, resultado que ratifica a importância dos programas de educação permanentes oferecidos pelas universidades abertas.

Graphical models and point pattern matching.

This paper describes a novel solution to the rigid point pattern matching problem in Euclidean spaces of any dimension. Although we assume rigid motion, jitter is allowed. We present a noniterative, polynomial time algorithm that is guaranteed to find an optimal solution for the noiseless case. First, we model point pattern matching as a weighted graph matching problem, where weights correspond to Euclidean distances between nodes. We then formulate graph matching as a problem of finding a maximum probability configuration in a graphical model. By using graph rigidity arguments, we prove that a sparse graphical model yields equivalent results to the fully connected model in the noiseless case. This allows us to obtain an algorithm that runs in polynomial time and is provably optimal for exact matching between noiseless point sets. For inexact matching, we can still apply the same algorithm to find approximately optimal solutions. Experimental results obtained by our approach show improvements in accuracy over current methods, particularly when matching patterns of different sizes.
