The Arabic natural language process (ANLP) community does not have an automatic generator of questions for texts in the Arabic language. Our objective is to provide it one. This paper presents a novel automatic question generation approach that generates questions as a form of support for children learning through the platform QUIZZITO. Our approach combines the semantic role labelling of PropBank (SRL) and the flexibility of question models. It essentially relates to an approach of instantiation model of representation based on an analysis focused on the semantics. This allowed us to capture the maximum sense of sentence given the flexibility of the grammar of the Arabic language. This model was written in a set of Patterns and Templates based on the REGEX languages. Our goal is to enrich Quizzito's online quiz platform, which contains more than 254.5k quizzes, and to provide it with a generator of Arabic language questions for children's texts. Our Arabic Question Generator system (AQG) is functional and reaches up to 86% f-measure.
Today, many sources of unstructured information such as social networks and blogs are more or less freely available on the web, and their volume is constantly growing, which constitutes a free gold mine for collecting public opinion. Opinion plays a crucial role because it can influence the decision-making process. Sentiment or opinion analysis is a discipline that can be used to meet decision-making needs, provide feedback to new product launches and marketing campaigns, and protect a company’s reputation, especially in social networking environments with massive data by exploiting textual data generated by users. In contrast to the techniques used, we have used and adapted in this study deep learning techniques: CNN and LSTM to identify their potential in this area and apply it to a corpus of Arabic data and in particular in Algerian dialect collected from social networks (50572 Facebook comments). We obtained promising results with an 85% f-measure. This represents a good start for an opinion analysis on the Algerian Dialect.
Abstract. In many fields using information systems (IS), knowledge is often represented by UML models, in particular, by including class diagrams. This formalism has the advantage of being controlled by a large community and therefore the perfect means of exchange. The desire to use an automated tool that formalizes the intellectual process of the expert from an IS specification texts seems interesting. Our problem is devoted to the presentation of a new strategy that allows us to move from an informal to a semi-formal representation model, which is the UML class diagram. This issue is not new. It has aroused great interest for a long time. The originality of our work is that these texts are in Arabic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
