Rigotrio At Semeval-2017 Task 9: Combining Machine Learning And Grammar Engineering For Amr Parsing And Generation
2017
By addressing both text-to-AMR parsing and AMR-to-text generation, SemEval-2017 Task 9 established AMR as a powerful semantic interlingua. We strengthen the interlingual aspect of AMR by applying the multilingual Grammatical Framework (GF) for AMR-to-text generation. Our current rule-based GF approach completely covered only 12.3% of the test AMRs, therefore we combined it with state-of-the-art JAMR Generator to see if the combination increases or decreases the overall performance. The combined system achieved the automatic BLEU score of 18.82 and the human Trueskill score of 107.2, to be compared to the plain JAMR Generator results. As for AMR parsing, we added NER extensions to our SemEva…
RDF* Graph Database as Interlingua for the TextWorld Challenge
2019
This paper briefly describes the top-scoring submission to the First TextWorld Problems: A Reinforcement and Language Learning Challenge. To alleviate the partial observability problem, characteristic to the TextWorld games, we split the Agent into two independent components: Observer and Actor, communicating only via the Interlingua of the RDF* graph database. The RDF* graph database serves as the “world model” memory incrementally updated by the Observer via FrameNet informed Natural Language Understanding techniques and is used by the Actor for the efficient exploration and planning of the game Action sequences. We find that the deep-learning approach works best for the Observer componen…
The silent work of speech. On an Enactive Grammar’s Insight
2019
Many research programs have been worked out in recent years in order to account for an apparently trivial aspect of the human language activity. We refer to the fact that every speaker hears the sound of his own words. Our paper aims to embed this empirical insight in the theoretical framework of the so-called enactive grammar. This choice is justified by the fact that the enactive grammar introduced a formal distinction which allows to provide a clear formulation of the jakobsonian assert. In order to highlight this point, the paper will be subdivided into seven sections. The first section will be devoted to the experience of the hearing oneself speak. The second one will examine this expe…
The international state of research on measurement of competency in higher education
2015
With the Program for International Student Assessment and Trends in International Mathematics and Science Study surveys, competency assessment became an important policy instrument in the school sector; only recently has international competency measurement gained attention in higher education with the Assessment of Higher Education Learning Outcomes (AHELO) feasibility study. As AHELO showed, measurement of competencies in higher education is a complex and multidimensional task, which poses great methodological challenges. These challenges arise out of the high diversity of degree courses, study programs, and institutions of higher education. Nevertheless, we need to address these challeng…
Measurement Advances and Challenges in Competency Assessment in Higher Education
2016
Domain-specific and generic competencies have become target outcomes of students' learning in higher education, and competency assessment plays an increasingly important role in higher education on an international scale. Recent reviews of the literature show that there is still a substantial lack of research on assessment practices in higher education, especially on measurement models and valid instruments for competency assessment. This special issue provides an overview of current international research and innovative developments in this research area, covering a broad range of assessment perspectives, addressing prevalent shortcomings of educational assessment practices, and presenting…
Mapping Elderly Citizen’s Computer and ICT Use in a Small-sized Norwegian Municipality
2015
In Norway, many citizensâ services are exclusively or at least delivered online. They usually require sufficient knowledge to use information and communication technologies (ICT). As part of an Interreg IV European project focused on e-inclusion for elderly, this work presents a study to map computer and Internet use among the elderly. The study was carried out in a small municipality of 10 000 inhabitants in Southern Norway, of whom15% were 65-year-olds or older. 178 replies out of 500 were obtained. Results showed that 9 out of 10 had access to and frequently used a computer at home. However, there still was 1 out of 5 who did not make effective use of ICT. Importantly, half of the resp…
CellMinerHCC: a microarray-based expression database for hepatocellular carcinoma cell lines.
2012
Background & Aims Therapeutic options for hepatocellular carcinoma (HCC) still remain limited. Development of gene targeted therapies is a promising option. A better understanding of the underlying molecular biology is gained in in vitro experiments. However, even with targeted manipulation of gene expression varying treatment responses were observed in diverse HCC cell lines. Therefore, information on gene expression profiles of various HCC cell lines may be crucial to experimental designs. To generate a publicly available database containing microarray expression profiles of diverse HCC cell lines. Methods Microarray data were analyzed using an individually scripted R program package. Dat…
The Gypsy Database (GyDB) of mobile genetic elements.
2007
In this article, we introduce the Gypsy Database (GyDB) of mobile genetic elements, an in-progress database devoted to the non-redundant analysis and evolutionary-based classification of mobile genetic elements. In this first version, we contemplate eukaryotic Ty3/Gypsy and Retroviridae long terminal repeats (LTR) retroelements. Phylogenetic analyses based on the gag-pro-pol internal region commonly presented by these two groups strongly support a certain number of previously described Ty3/Gypsy lineages originally reported from reverse-transcriptase (RT) analyses. Vertebrate retroviruses (Retroviridae) are also constituted in several monophyletic groups consistent with genera proposed by t…
eWOM in reward-based crowdfunding platforms: a behavioral approach
2020
[EN] Electronic word of mouth (eWOM) plays a crucial role in influencing purchasing decisions of consumers in situations governed by asymmetric information. In this context, investors in reward-based crowdfunding platforms might modify their purchasing intentions according to recommendations of peers and/or experts. The goal of this paper is to analyze the power of eWOM to shape consumers’ purchasing decisions. We do so by conducting an experiment through Amazon Mechanical Turk (AMT). This online experimental tool allows for an instant access to a large and culturally diverse subject pool, facilitating behavioral research requiring large amounts of subjects. By recreating a reward-based cro…
