Arabic Cooperative Answer Generation via Wikipedia Article Infoboxes
No full text[EN] The typical question-answering system is facing many challenges related
to the processing of questions and information resources in the extraction
and generation of adequate answers. These challenges increase when the requested
answer is cooperative and its language is Arabic. In this paper, we propose
an original approach to generate cooperative answers for user-definitional
questions designed to be integrated in a question-answering system. This approach
is mainly based on the exploitation of the semi-structured Web
knowledge which consists in using features derived from Wikipedia article infoboxes
to generate cooperative answers. It is globally independent of a particular
language, which gives it the ability to be integrated in any definitional question-answering
system. We have chosen to integrate and experiment it in a definitional
question-answering system dealing with the Arabic language entitled
DefArabicQA. The results showed that this system has a significant impact on
the approach efficiency regarding the improvement of the quality of the answer.The work of the third author was partially funded by the Spanish Ministry of Economy, Industry and Competitiveness (MINECO) under the SomEMBED research project (TIN2015-71147-C2-1-P) and by the Generalitat Valenciana under the grant ALMAMATER (PrometeoII/2014/030).Trigui, O.; Belguith, L.; Rosso, P.

A cross-cultural study on consumer preferences for olive oil
No full textIn this paper, we study consumer preferences for olive oil across four countries (Denmark, France, Tunisia, and the US). Based on a large-scale study with olive oil consumers (N = 3,462), we use the Best-Worst Scaling method to measure perceived importance for product attributes known to influence consumer choice. Our results show that consumers across all countries rate type, price, prior experience, and country of origin as important product attributes. On the other hand, packaging, label design, and brands are considered as less important product attributes. While the perceived importance for olive oil attributes differs across countries, the order of importance is almost similar for all countries. We further derive a three-segment solution and describe each segment based on its attitudinal beliefs, usage, and socio-demographic profile. We discuss implications for the study of consumer preferences for olive oil and provide managerial insights.© 2021 The Author(s). Published by Elsevier Ltd.
