Currently, the school children usually spend a lot of time on the games in their recreational activities and some of them are even addicted to the games. Compared with other extracurricular activities, the e-Learning system reflects the fact that school children are very interested in the games. As a result, educators have lately craved to develop effective teaching activities that allow the school children to learn some subjects and to play the games simultaneously.  Therefore, this study is based on an e-Learning system which combines the serious game by Unity3D Game Engine with augmented reality (AR). Students are able to acquire their knowledge and to foster logical skills via this game-based e-Learning system.  According to its efficacy and utilities, this study has assessed and compared the game-based e-Learning system with the traditional learning and other e-Learning systems. The experimental results have indicated that the proposed game-based e-Learning system can outperform other existing systems.
Predictive analysis of instruction in science to students’ declining in-terest in science-An analysis of gifted students of sixth - and seventh-grade in Taiwan
Authors: Hsieh Chia-Yen
Published: June 2020

Students’ interest in science declines substantially in the transition from elementary to secondary education. Using students’ ratings of their instruction on the topic of oxidation-reduction reaction, we examined if changes in instructional practices accounted for differences in situational interest in science imagination instruction and enduring individual interest in science imagination between elementary and secondary school classrooms. Multilevel regression analyses were conducted for a sample of 162 sixth - and 161 seventh-grade gifted classrooms. The use of student experiments, the elicitation of student explanations, and lack of clarity accounted to varying degrees for disparities in science interest between grade levels. The impact of instructional practices on individual interest was mediated by situational interest.

Published: June 2020

Discectomy with replacement of disc is one possibility for treating disc perforation where conservative, mini-invasive therapy and arthroscopy has had no effect. Allogenic or autologous materials are used to replace the disc. The authors assess the use of a free fat flap (FFF) in 19 patients who in 2015–2016 underwent a unilateral discectomy with disc replacement. In the retrospective 24-month follow-up study a total of 16 patients (84%) were free of difficulties. 24 months after the operation mouth opening was on average 39.3 mm, pain (VAS – visual analog scale (0–10) was assessed on average at 0.3). Crepitus was present after 24 months in 37.5% of patients (6 patients). An assessment of changes in joint structures on cone beam computed tomography (CBCT) for these patients 24 months after the operation showed the progression of flattening of the joint head, in one case unevenness of the joint head. In 3 cases (16%) there was a recurrence of the state within 24 months – in all cases with clinical manifestations of pain and limited mobility, for these patients on the CBCT significant unevennesses of the joint head, subchondral cysts were noted. The authors find discectomy with use of FFF to be an effective method of treatment with a minimum of complications. However, one should take into account the relatively short time of monitoring after the operation (2 years) and limited number of patients in the cohort (19 patients).

Introduction
The Silence of Fragmentation
Authors: Crockett Talia E.
Published: June 2020

Holocaust literature is a challenging space in which to write, seeking toa convey an event that cannot truly be represented in words: the systematic destruction of millions of lives, an estimated 1.5 million of which were children who were permanently silenced in the concentration camps. Young adult authors have the added challenge of creating texts that convey the trauma of the Holocaust in ways that are accessible to teenage readers, attempting to reconcile a moral duty to historical accuracy with the desire for an engaging, empathetic novel. This article addresses the evolving use of silence and fragmentation to represent the trauma of the Holocaust in three young adult novels from the last thirty-five years: Jane Yolen’s Briar Rose (1992), Marianne Fredriksson’s Simon och ekarna (Simon and the Oaks, 1985), and Sharon Hart-Green’s Come Back for Me (2017). As this event recedes further into history, historical knowledge of it may be in decline, while anti-Semitism is still prevalent. The Holocaust is something about which we must continue to speak, but now we must do so in different ways. Building on the work of Lydia Kokkola and Leona Toker, this article demonstrates how silence has been used to represent the trauma of the Holocaust as we become increasingly removed from the event. If a traumatic event is understood as it returns to a victim in shards of memories, then fragmentation can be used to recreate the experience for a reader, representing the chaos as opposed to attempting to order it. By writing in a form rife with silent gaps in narrative, knowledge, and understanding, young adult authors can select that which they reveal to their readers according to present historical knowledge while simultaneously mimicking the chaotic, fractured experience of trauma itself. Ultimately, that which is not said becomes as powerful as that which is.
Seeking Asylum, Speaking Silence
Authors: King Helen
Published: June 2020

“How could she ever put those terrible pictures into words?” (Naidoo, Truth 51). This question is at the heart of Beverley Naidoo’s The Other Side of Truth (2000), which narrates the trauma of Nigerian asylum seeker children Sade and Femi as they flee to Britain. Speech and silence are ambivalent within the text, fluctuating in meaning dependant on the social context in which they are enacted. Showing this text to be primarily a narrative of activism, I explore how Naidoo’s representations of trauma inform her critique of the British immigration system. This text invites a reading that draws on recent postcolonial theories of trauma. Using both textual and paratextual analysis of the novel and Naidoo’s archive, held by Seven Stories: The National Centre for Children’s Books in Britain, I draw on Forter’s model of psychosocial trauma to demonstrate that the trauma the protagonists face is a result of their encounter with a racist society and bureaucracy. Reflecting Kertzer’s claim that social justice should be central in trauma narratives for children, Naidoo shows healing from trauma to be the locus of political awakening for both characters and implied reader. The aim of this article is to integrate contemporary models of postcolonial trauma with an understanding of the activist nature of Naidoo’s work, showing that in this sort of children’s trauma narrative, the site of healing from trauma is simultaneously the site of social change. Since the trauma that the child protagonists face is a social phenomenon, the speech that allows the children to begin to heal is similarly socially situated, and their healing is synonymous with social justice.

Authors: Shen Yuzhou , Ma Jiancheng , Jiang Junsheng , Chen Zhilin , Yan Wenzhu , Wang Yue , Wang Feng , Liu Li
Published: June 2020

Nonviral targeting technology has become promising as a form of gene therapy for diseases and injuries, such as Achilles tendon injuries. In this study, we used avidin–biotin bridge and positive–negative charge attractions to load the intercellular adhesion molecule-1 (ICAM-1) antibody and the basic fibroblast growth factor (bFGF) plasmid onto the surface of the microbubbles. The saturated loading capacity for 1.1 × 108microbubble was 6.55 ± 0.53 µg. We established the ICAM-1 antigen microenvironment using tumor necrosis factor-alpha-stimulated human umbilical vein endothelial cells and found the targeting ability of the prepared microbubblesin vitro.In vivo, we also found that the injected targeted bFGF gene microbubbles expressed the bFGF gene better when compared with that of the control group. Furthermore, we evaluated adhesions after Achilles tendon injuries in rabbits using hematoxylin and eosin and immunohistochemical (IHC) staining methods. The collagen fibers were properly arranged in the tendon, and there was greater cellularity inside the tendon sheath and a clearer boundary between the internal and external tendon sheath than that of the control group. IHC staining showed greater ICAM-1 expression inside the tendon sheath when compared with outside the tendon sheath. In conclusion, targeted microbubbles can be a useful carrier of genes to provide gene therapy for the prevention of adhesions after tendon injury.
Critical Analysis on Historiography of Gamelan Bebonangan In Bali
Authors: Santosa Hendra
Published: June 2020

Historical sources on gamelan Bebonangan refer to the different shapes and forms of the ensemble. This inevitably results in perplexity on the origin, shapes, and forms of gamelan Bebenongan. The paper, therefore, aims to redress the confusion by rewriting it through critical history, a type of criticism on historical sources related to the term gamelan Bebonangan in Bali. The method used for the paper is historical approaches that include heuristics, criticism, interpretation, and historiography as the finale. The word bebonangan is not found in historical sources of Balinese karawitan in the form of Old Javanese literature, which is today preserved in Bali and the Balinese literature itself. The only literary work that mentions these pencon-ed instruments is the Book of Pararaton, calling the as reyong instruments. The Book of Prakempa refers to the instruments in names such as reyong barangan and reyong pangageng. By indicating that the reyong instrument becomes the main instrument, one may expect peculiarity in the claims. It may be pointed out that opinions have been led in the beginning by the foreign influence to impose the view to the Balinese to challenge their own identity and, at the same time to be applauded for their arts and culture.Sumber sejarah tentang gamelan Bebonangan yang menunjuk bentuk dan wujud yang berbeda. Hal ini tentu saja menyebabkan kesimpang siuran tentang asal-usul dan wujud gamelan Bebonangan itu sendiri. Oleh karenanya penulisan ini bertujuan untuk meluruskan kesimpangsiuran yang terjadi dengan menuliskannya melalui kritik terhadap sumber-sumber sejarah istilah gamelan Bebonangan di Bali. Metode yang dipergunakan yaitu metode sejarah yaitu heuristik, kritik, interpretasi atau penafsiran, dan terakhir adalah historiografi. Kata bebonangan tidak ditemukan dalam sumber-sumber sejarah karawitan Bali yang berupa literatur kesusastraan Jawa Kuna yang sekarang diawetkan di Bali dan literatur kesusastraan Bali sendiri. Satu-satunya karya kesusastraan yang menyebutkan instrumen berpencon ini adalah kitab pararaton yang menyebutnya dengan instrumen reyong. Prakempa menyebutkan instrumen-instrumen gamelan Bebonangan antara lain reyong Barangan dan reyong Pangageng. Merujuk hal tersebut dimana instrumen reyong merupakan instrumen utama, maka tentulah hal ini menjadi sebuah keanehan. Sepertinya telah terjadi penggiringan sejak awal, adanya pengacauan asing telah memaksakan orang Bali untuk mempertanyakan dasar identitas mereka, pada saat yang sama mereka juga mendapat sanjungan untuk seni dan budayaannya.

This research talks about the process of Islamization in Indramayu. The Islamization in Indramayu raises three main questions. The first question is, where was the arrival of Islam in Indramayu. Second, when is the appearance of Islam. Third, who has a role in the Islamization process. This research uses the historical method, which consists of four stages: heuristic, criticism, interpretation, and historiography. This method was then collaborated with Islamic social movement theory to analyze the ideology of leadership and movement mobility of the propagator group of Islam in Indramayu. The results showed that the arrival of Islam in Indramayu came from the port of Cimanuk. Then spread to various areas, including in the countryside. Second, Islam has been dating in Indramayu since the 15th century. Third, some communities play a role in Islamization in Indramayu. The communities were very influential until the 19th century. They consisted of the Arab community and the adherents of the tarekat, especially from Cirebon. The first order to develop was Syattariyah. Meanwhile, the Arabic community leader from Cirebon was Sayyid Abdur Rahman bin Muhammad Basy-Syaiban. He is a figure who originated from the Hadramaut in the early seventeenth century.Penelitian ini berbicara tentang proses islamisasi di Indramayu.

Published: June 2020

This study aims to identify the challenges faced by teachers and the efforts made in the implementation of HOTS-based history learning. In this study, a qualitative method was used by taking research at the Lab School in Kebayoran Jakarta. The analysis was carried using Strauss & Corbin grounded theory approach. The results illustrate three interrelated things, namely the concept of HOTS used, implementation, and challenges faced by history teachers. This study shows that the difficulty faced by history teachers in teaching and learning history based on HOTS is that assessment has been carried out using the HOTS model. On the other hand, training in learning that supports HOTS has not been provided to teachers, many curriculum demands, teacher competencies/skills, lack of time in the learning process, and the learning design made by the teacher does not yet support HOTS. The efforts to answer these challenge can be overcome by (1) increasing teacher understanding/mastery of HOTS concepts, (2) the planning of learning devices arranged to suit the needs of students, and (3) during the implementation of learning using models that support HOTS namely inquiry learning.Penelitian ini bertujuan untuk mengidentifikasi tantangan yang dihadapi guru dan upaya yang dilakukan dalam pelaksanaan pembelajaran sejarah berbasis HOTS. Dalam penelitian ini, metode kualitatif digunakan dengan mengambil penelitian di SMA Lab School Kebayoran Jakarta. Analisis dilakukan dengan menggunakan pendekatan teori ground Strauss & Corbin. Hasil penelitian menggambarkan tiga hal yang saling terkait, yaitu konsep HOTS yang digunakan, implementasi, dan tantangan yang dihadapi oleh guru sejarah. Studi ini menunjukkan bahwa kesulitan yang dihadapi oleh guru sejarah dalam pengajaran dan pembelajaran sejarah berdasarkan HOTS adalah penilaian telah dilakukan dengan menggunakan model HOTS. Di sisi lain, pelatihan dalam pembelajaran yang mendukung HOTS belum diberikan kepada guru, banyak tuntutan kurikulum, kompetensi / keterampilan guru, kurangnya waktu dalam proses pembelajaran, dan desain pembelajaran yang dibuat oleh guru belum mendukung HOTS. Upaya menjawab tantangan ini dapat diatasi dengan (1) peningkatan pemahaman guru / penguasaan konsep HOTS, (2) perencanaan perangkat pembelajaran yang disesuaikan dengan kebutuhan siswa, dan (3) selama pelaksanaan pembelajaran menggunakan model yang mendukung HOTS yaitu pembelajaran inkuiri.

Published: June 2020

Se realizó la implementación de un modelo de calidad del agua superficial, a través del cual se procuraba hacer un primer acercamiento a los procesos de modelado matemático como insumo para la gestión integrada de la cuenca media del río Virilla. El estudio se desarrolló específicamente en un tramo de 20 km que inicia en San Miguel de Santo Domingo y finaliza en San Antonio de Belén, se tiene como principal afluente el río Tibás y la inclusión de algunas descargas de aguas residuales provenientes de diversas actividades productivas. El enfoque que se utilizó fue cuantitativo, mediante el modelo MOHID Land con la aplicación de datos experimentales e históricos de las variables necesarias para el modelado. El modelo implementado es un programa numérico capaz de simular la dinámica existente entre agua-suelo y los procesos de transporte de solutos; en este caso, se eligió modelar la concentración de dos indicadores de calidad: el oxígeno disuelto y la demanda bioquímica de oxígeno. Los resultados obtenidos en la modelación presentaron un buen ajuste en contraste con los datos utilizados para la validación del modelo, los porcentajes de error obtenidos son calificados como muy buenos, buenos y satisfactorios, lo que en general se puede describir como un modelo aplicable. A pesar de esto, es necesario el desarrollo de una calibración más robusta que a su vez se acompañe de un análisis de sensibilidad. Es importante que en el nivel país exista una mayor diseminación del uso de esta herramienta para la gestión integrada del recurso hídrico, este estudio sirve como base para la futura modelación de otros parámetros fisicoquímicos del cuerpo de agua, así como la aplicación del mismo en otros ríos similares.

Factors in Labor Activity of Modern Russian Technical Intelligentsia
Authors: Makarenko Ekaterina I.
Published: June 2020

Introduction. The real situation in the economic, political and educational spheres hinders the development of intellectual and professional resources of technical intelligentsia. The purpose of the study is to identify objective conditions and subjective factors that determine the labor activity of modern Russian technical intelligentsia as a personnel basis for socio-economic changes and innovative transformations in the country.

Materials and Methods. Official statistics and legislative acts were used as the materials for an analysis of the objective conditions. The methodological principles of historicism and socio-historical continuity, the methods of mathematical statistics were applied. When interpreting subjective factors, the empirical data obtained using the methods of the mass survey “Modernization of the Economy and Technical Intelligentsia” and the expert survey “Innovative Activity of Technical Intelligentsia” were examined. The surveys made it possible to reveal technical intelligentsia’s opinion – an assessment of current events in terms of adaptation to market relations and crises of recent years, job satisfaction, material remuneration for one’s work, value orientations.

Results. The study made it possible to identify the objective conditions (the economic situation of the country, the state of institutions of education, etc.) and the subjective factors (the degree and level of labor adaptation of technical intelligentsia to the ongoing socio-economic transformations of recent decades, job satisfaction, etc.) that characterize modern Russian technical intelligentsia. The performed analysis of these conditions and factors indicates the difficulties for implementing a large-scale innovative breakthrough both in Russia’s economy and society as a whole.

Discussion and Conclusion. Modern objective conditions determining the development of technical intelligentsia do not contribute to the completion of its traditional social mission – to be the pillar of scientific, technological and innovative transformations. The article is of practical importance for government agencies at various levels, for public organizations working to improve policies in the field of innovation in industry, science and education. Empirical data can be used for further scientific interpretations, as well as for diagnostics and advice on targeted support to enterprises and organizations in the productive sector.
Monetary policy independence and floating exchange rates: what does the Brazilian evidence tell us?
Authors: GONÇALVES CARLOS EDUARDO SOARES
Published: June 2020

ABSTRACT Some authors have advocated that shifting from fixed exchange rates to floating regimes has not delivered better economic outcomes to developing countries. As the argument goes, pervasive fear of floating in these economies has prevented drops in real interest rates and, more importantly, has been a hindrance in the way towards more monetary policy autonomy. This paper presents evidence suggesting this may not be the case for Brazil. More precisely, there are signs that fear of floating was less acute here (presumably due to low exchange rate pass-through) than elsewhere, and also that policymakers are now targeting monetary policy principally to domestic objectives.
On Open Systems
Authors: CHICK VICTORIA
Published: June 2020

ABSTRACT To many, economics is seen as increasingly divorced from reality. I shall argue that one of the causes of this divorce is the attachment to closed-system theorising, and advocate instead the method of open systems with partial and temporary closures. Definitions of closed and open systems are examined. It is evident that there are many different criteria which may define open systems. Theorists differ in their emphasis on one or other criterion. There are also different dimensions of openness: openness to non-economic factors; the openness of economic theories themselves; the interplay of micro- and macro-economics; and the treatment of time. These are explored, using Keynes’s General Theory as a case study of an open system.
COVID-19-related challenges in dental education: experiences from Australia, Brazil, and the USA
Authors: Peres Karen G , Reher Peter , Castro Ricardo Dias de , Vieira Alexandre Rezende
Published: June 2020

Aim: To describe the management of dental education in three dental schools during the COVID-19 crisis. Methods: Adopted strategies in the Federal University of Paraíba (UFPB), Brazil, University of Pittsburgh (UP), USA, and Griffith University (GU), Australia were detailed. Results: In the UFPB, all on-site teaching was suspended, and resources for distance learning set up as a supplementary semester to be available as face to face classes later. A protocol for clinical care followed safety measures recommended by Brazilian official health institutions. The adequacy of the physical structure, human resources, and personal protective equipment (PPE) acquisition for the return to clinical activities are currently under discussion. In the UP, learning activities were shifted to virtual teaching using lecture recordings and live sections. All elective patients care was postponed. Urgent dental cases were discussed via teledentistry. The physical layout of the dental clinics and pre-clinical laboratories were changed, allowing a safe distance between students. In the GU, all clinical and pre-clinical activities were cancelled, and theoretical activities were maintained online for all students. Several clinically based scenarios where created and delivered in the format of online problem-based learning. The reception area was redesigned, ensuring social distancing. Safety measures follow the Australia Dental Association. Conclusions: Dealing with dental education depends on the stage of the epidemic and the characteristics of each country.

A pandemia, juntamente com o óbvio impacto relacionado à saúde, também representa uma séria ameaça ao bem-estar psicológico dos indivíduos e resultou em mudanças comportamentais significativas. O principal objetivo deste artigo foi descrever a resposta psicocomportamental a esta crise entre a população da região central da cidade de São Paulo, compreendendo os bairros da Bela Vista, Bom Retiro, Cambuci, Consolação, Liberdade, República, Sé e Santa Cecília, no mês de abril de 2020. Um questionário estruturado e autoaplicável foi construído, com base em pesquisas precedentes avaliando o impacto psicológico e as mudanças comportamentais referentes ao novo cenário de Pandemia na cidade de São Paulo. Os questionários foram disponibilizados on-line e foram endereçados a qualquer indivíduo residente nos bairros selecionados, durante abril de 2020. Os dados foram analisados usando o Statistical Package for the Social Sciences (SPSS) versão 21.0 para identificar possíveis riscos fatores para mudanças psicológicas e comportamentais. Foram estudados dados de 400 participantes residentes na região metropolitana de São Paulo. A disseminação do novo vírus resultou no desenvolvimento subsequente de medos na população-alvo estudada, com a maioria dos entrevistados se sentindo ansiosa diariamente (62,5%). Os participantes temiam ir aos mercados (88,8%), preocupavam-se com a saúde de seus familiares (94,5%) e sentiam-se pouco confiantes com as medidas atuais de controle de infecção (71%). Níveis de medo significativamente elevados foram observados entre pessoas com mais de 35 anos de idade. Eles eram mais propensos a temer pela segurança de sua saúde, mesmo em casa (p = 0,06). Enquanto isso, o aumento dos níveis de ansiedade devido ao uso de mídias sociais entre pessoas com menos de 35 anos resultou em comportamentos de fuga (p = 0,04). Houve maior tendência para os graduados temerem pela segurança de sua saúde, mesmo em casa (p < 0,01). Além disso, mais de três quartos dos participantes da pesquisa incorporaram mudanças em seu comportamento para garantir sua segurança, ou seja, contato físico reduzido (86,5%) e visitas a unidades de saúde (74,5%), planos cancelados (84,5%) e lavagem das mãos mais frequentemente (87%). Como resultados, houve o aumento dos níveis de ansiedade que um indivíduo experimentava regularmente em relação à sua saúde, à saúde de seus próximos, a certos comportamentos de prevenção como resultado da doença e a mudanças de comportamento da amostra analisada.

Published: June 2020

This article sought to identify articles published on the action of the dentist in the application of the Oral Rapid HIV Test (ORHT). The search was undertaken from October 2018 to August 2019, and investigated the databases PubMed, Cochrane, Lilacs e Scopus, from articles published in the English language during the period from 2015 to 2019. Altogether 89 bibliographical references were found, after repetitions and articles that did not deal with the subject were eliminated, a total of 11 remained for analysis. Five articles reported the direct clinical action of the dentist and the remainder dealt with research on the oral rapid test. The studies showed how the dentist may contribute meaningfully to public health by the identification of persons infected with HIV.
Causally Denoise Word Embeddings Using Half-Sibling Regression
Authors: Yang Zekun , Liu Tianlin
Published: June 2020

Distributional representations of words, also known as word vectors, have become crucial for modern natural language processing tasks due to their wide applications. Recently, a growing body of word vector postprocessing algorithm has emerged, aiming to render off-the-shelf word vectors even stronger. In line with these investigations, we introduce a novel word vector postprocessing scheme under a causal inference framework. Concretely, the postprocessing pipeline is realized by Half-Sibling Regression (HSR), which allows us to identify and remove confounding noise contained in word vectors. Compared to previous work, our proposed method has the advantages of interpretability and transparency due to its causal inference grounding. Evaluated on a battery of standard lexical-level evaluation tasks and downstream sentiment analysis tasks, our method reaches state-of-the-art performance.
Automatic Generation of Headlines for Online Math Questions

Mathematical equations are an important part of dissemination and communication of scientific information. Students, however, often feel challenged in reading and understanding math content and equations. With the development of the Web, students are posting their math questions online. Nevertheless, constructing a concise math headline that gives a good description of the posted detailed math question is nontrivial. In this study, we explore a novel summarization task denoted as geNerating A concise Math hEadline from a detailed math question (NAME). Compared to conventional summarization tasks, this task has two extra and essential constraints: 1) Detailed math questions consist of text and math equations which require a unified framework to jointly model textual and mathematical information; 2) Unlike text, math equations contain semantic and structural features, and both of them should be captured together. To address these issues, we propose MathSum, a novel summarization model which utilizes a pointer mechanism combined with a multi-head attention mechanism for mathematical representation augmentation. The pointer mechanism can either copy textual tokens or math tokens from source questions in order to generate math headlines. The multi-head attention mechanism is designed to enrich the representation of math equations by modeling and integrating both its semantic and structural features. For evaluation, we collect and make available two sets of real-world detailed math questions along with human-written math headlines, namely EXEQ-300k and OFEQ-10k. Experimental results demonstrate that our model (MathSum) significantly outperforms state-of-the-art models for both the EXEQ-300k and OFEQ-10k datasets.
Neural Simile Recognition with Cyclic Multitask Learning and Local Attention
Authors: Zeng Jiali , Song Linfeng , Su Jinsong , Xie Jun , Song Wei , Luo Jiebo
Published: June 2020

Simile recognition is to detect simile sentences and to extract simile components, i.e., tenors and vehicles. It involves two subtasks: simile sentence classification and simile component extraction. Recent work has shown that standard multitask learning is effective for Chinese simile recognition, but it is still uncertain whether the mutual effects between the subtasks have been well captured by simple parameter sharing. We propose a novel cyclic multitask learning framework for neural simile recognition, which stacks the subtasks and makes them into a loop by connecting the last to the first. It iteratively performs each subtask, taking the outputs of the previous subtask as additional inputs to the current one, so that the interdependence between the subtasks can be better explored. Extensive experiments show that our framework significantly outperforms the current state-of-the-art model and our carefully designed baselines, and the gains are still remarkable using BERT.

Span Model for Open Information Extraction on Accurate Corpus
Authors: Zhan Junlang , Zhao Hai
Published: June 2020

Open Information Extraction (Open IE) is a challenging task especially due to its brittle data basis. Most of Open IE systems have to be trained on automatically built corpus and evaluated on inaccurate test set. In this work, we first alleviate this difficulty from both sides of training and test sets. For the former, we propose an improved model design to more sufficiently exploit training dataset. For the latter, we present our accurately re-annotated benchmark test set (Re-OIE2016) according to a series of linguistic observation and analysis. Then, we introduce a span model instead of previous adopted sequence labeling formulization for n-ary Open IE. Our newly introduced model achieves new state-of-the-art performance on both benchmark evaluation datasets.

Authors: Zhong Haoxi , Xiao Chaojun , Tu Cunchao , Zhang Tianyang , Liu Zhiyuan , Sun Maosong
Published: June 2020

We present JEC-QA, the largest question answering dataset in the legal domain, collected from the National Judicial Examination of China. The examination is a comprehensive evaluation of professional skills for legal practitioners. College students are required to pass the examination to be certified as a lawyer or a judge. The dataset is challenging for existing question answering methods, because both retrieving relevant materials and answering questions require the ability of logic reasoning. Due to the high demand of multiple reasoning abilities to answer legal questions, the state-of-the-art models can only achieve about 28% accuracy on JEC-QA, while skilled humans and unskilled humans can reach 81% and 64% accuracy respectively, which indicates a huge gap between humans and machines on this task. We will release JEC-QA and our baselines to help improve the reasoning ability of machine comprehension models. You can access the dataset from http://jecqa.thunlp.org/.
