Transformer-based language models for semantic search and mobile applications r...

Search engines are being extensively used by Mobile App Stores, where millions of users world-wide use them every day. However, some stores still resort to simple lexical-based search engines, despite the recent advances in Machine Learning, Information Retrieval, and Natural Language Processing, which allow for richer semantic strategies. This work proposes an approach for semantic search of mobile application...

Semantic search of mobile applications using word embeddings

This paper proposes a set of approaches for the semantic search of mobile applications, based on their name and on the unstructured textual information contained in their description. The proposed approaches make use of word-level, character-level, and contextual word-embeddings that have been trained or fine-tuned using a dataset of about 500 thousand mobile apps, collected in the scope of this work. The propo...

Magnetic fingerprint of Southern Portuguese speleothems and implications for pa...

Environmental magnetism of speleothems is still in its early stage of development. Here we report on our investigation of the environmental and paleomagnetic information that has been recorded in speleothems, and what are the factors that control its preservation and reliability. To address these issues, we used a multidisciplinary approach, including rock magnetism, petrography, scanning electron microscopy, s...

Frequency independent patterns from double shell lenses fed by leaky wave feeders

This work aims at designing a wideband leaky lens antenna capable of providing frequency independent patterns over a wide frequency band of operation, about one octave, using connected array of leaky slots as lens feeder in presence of a double shell lens. In addition to on-axis feeding, offset feeding is also studied in order to increase the scanning performance of the antenna system within the proposed freque...

Validade estrutural do questionário de atitudes face às ciências da natureza: E...

As Ciências da Natureza devem ajudar os alunos a adquirir um conjunto de conhecimentos e competências essenciais para iniciar o estudo das ciências. Pela necessidade de dispor de instrumentos validados para a população portuguesa, apresentamos um estudo de validação do Questionário de Atitudes Face às Ciências da Natureza (QAFCdN) para alunos portugueses. Neste estudo participaram 487 alunos do 2º ciclo do Ensi...

Validade estrutural do questionário de atitudes face às ciências naturais: Estu...

As disciplinas de Ciências são fundamentais para qualquer currículo. A investigação aponta para a existência de relação entre as atitudes do indivíduo e a aprendizagem. Atendendo à necessidade de dispor de instrumentos validados para a população portuguesa, apresentamos um estudo de validação do Questionário de Atitudes Face às Ciências Naturais para alunos portugueses. Este estudo incidiu sobre uma amostra de ...
