ToCT: A task ontology to manage complex templates

Natural language interfaces are a well-known approach to grant non-experts access to semantic web technologies. A number of such systems use simple templates to achieve that for English and more elab-orate solutions for other languages. They keep being designed from scratch in an ad hoc manner, since there is no shared conceptualisation of simple templates and there is no model that is formalised using a Semantic Web language to apply the techniques to itself. We aim to address this by proposing a general-purpose solution in the form of a novel model for templates, formalised as a task ontology in OWL,calledToCT. We used it to develop an ontology-driven text generator for isiZulu, a morphologically-rich language, to test its capabilities. The generator verbalises the TBox of an ontology as validationq uestions. This evaluation showed that the task ontology is sufficiently expressive for the template design, which was subsequently verified with user evaluations who judged the texts positivel

A classification of grammar-infused templates for ontology and model verbalisation

Involving domain-experts in the development, maintenance, and use of knowledge organisation systems can be made easier through the introduction of easy-to-use interfaces that are based on natural language. Well resourced languages make use of natural language generation techniques to provide such interfaces. In particular, they often make use of templates combined with computational grammar rules to generate grammatically complex text. However, there is no model of pairing templates and computational grammar rules to ensure suitability for less-resourced languages. These languages require a modular design that ensures grammar detachability so as to allow grammar re-use across domains and applications. In this paper, we present a model and classification scheme for grammar-infused templates suited for less-resourced languages and classify existing systems that make use of them. We have found that of the 15 systems that pair templates and grammar rules, and their 11 distinct template types, 13 have support for detachable grammars

Surface realization architecture for low-resourced African languages

There has been growing interest in building surface realization systems to support the automatic generation of text in African languages. Such tools focus on converting abstract representations of meaning to text. Since African languages are low-resourced, economical use of resources and general maintainability are key considerations. However, there is no existing surface realizer architecture that possesses most of the maintainability characteristics (e.g., modularity, reusability, and analyzability) that will lead to maintainable software that can be used for the languages. Moreover, there is no consensus surface realization architecture created for other languages that can be adapted for the languages in question. In this work, we solve this by creating a novel surface realizer architecture suitable for low-resourced African languages that abide by the features of maintainable software. Its design comes after a granular analysis, classification, and comparison of the architectures used by 77 existing NLG systems. We compare our architecture to existing architectures and show that it supports the most features of a maintainable software product.Hasso Plattner Institute for Digital Engineering through the HPI Research School at UCT and the National Research Foundation (NRF) of South Africahttps://dl.acm.org/journal/tallipInformatic

Proceedings of the 60th Annual Meeting of the Association for Computational Linguistics: Student Research Workshop

Indonesian and Malay are underrepresented in the development of natural language processing (NLP) technologies and available resources are difficult to find. A clear picture of existing work can invigorate and inform how researchers conceptualise worthwhile projects. Using an education sector project to motivate the study, we conducted a wide-ranging overview of Indonesian and Malay human language technologies and corpus work. We charted 657 included studies according to Hirschberg and Manning's 2015 description of NLP, concluding that the field was dominated by exploratory corpus work, machine reading of text gathered from the Internet, and sentiment analysis. In this paper, we identify most published authors and research hubs, and make a number of recommendations to encourage future collaboration and efficiency within NLP in Indonesian and Malay

Text Complexity Levels and Second Language Reading Performance in Indonesia

This study examined the effect of text complexity on L2 reading performance of Indonesian students with different language proficiency levels. Four passages consisting of two low complexities and two high complexities were given to participants. Text complexity levels were analysed using Flesch’s reading ease index or grade level formula (Flesch, 1948, 1951, 1979),Text-Evaluator designed by Education Testing Service (2013), and Coh-Metrix version 3.0 indexes (McNamara, Louwerse, Cai & Graesser, 2013). Additionally, Pearson’s correlation, regression and one-way ANOVA were employed. There were 1054 university EFL students participating in this study. The findings revealed that text complexity had a moderate correlation and significantly contributed to L2 reading. Keywords: text complexity, reading comprehension, readabilit

EFL Teachers’ Reconciliation with Moral Forces Brought into Curriculum

This paper presents EFL teachers’ strategies when reconciling with moral forces underpinning Indonesian curricula: School-based curriculum and character education policy. While School-based curriculum allows teachers to develop more flexible EFL classes, the character education policy promotes such controlled EFL classes that the teachers are required to focus on students’ moral behaviour. The moral forces of the school-based curriculum resonate with communicative language teaching regarding the teachers’ opportunity for developing teaching materials to meet learners’ needs. This paper suggests that the EFL teachers have particular dilemmas as they attempt to embrace the moral forces of two curricula.

Factors Influencing Customer Satisfaction towards E-shopping in Malaysia

Online shopping or e-shopping has changed the world of business and quite a few people have decided to work with these features. What their primary concerns precisely and the responses from the globalisation are the competency of incorporation while doing their businesses. E-shopping has also increased substantially in Malaysia in recent years. The rapid increase in the e-commerce industry in Malaysia has created the demand to emphasize on how to increase customer satisfaction while operating in the e-retailing environment. It is very important that customers are satisfied with the website, or else, they would not return. Therefore, a crucial fact to look into is that companies must ensure that their customers are satisfied with their purchases that are really essential from the ecommerce’s point of view. With is in mind, this study aimed at investigating customer satisfaction towards e-shopping in Malaysia. A total of 400 questionnaires were distributed among students randomly selected from various public and private universities located within Klang valley area. Total 369 questionnaires were returned, out of which 341 questionnaires were found usable for further analysis. Finally, SEM was employed to test the hypotheses. This study found that customer satisfaction towards e-shopping in Malaysia is to a great extent influenced by ease of use, trust, design of the website, online security and e-service quality. Finally, recommendations and future study direction is provided. Keywords: E-shopping, Customer satisfaction, Trust, Online security, E-service quality, Malaysia
