We introduce the first system towards the novel task of answering complex multisentence recommendation questions in the tourism domain. Our solution uses a pipeline of two modules: question understanding and answering. For question understanding, we define an SQL-like query language that captures the semantic intent of a question; it supports operators like subset, negation, preference and simi...

Recent progress and remaining challenges related to the understanding and prediction of turbulent flow are described. This is done by explaining the need for the development and basic features of unified turbulence models which integrate, recover and extend well known existing computational methods for turbulent flow calculations. The availability of unified turbulence models enables a signific...

The present work seeks to understand the use of cosmetic creams and perception natural eco-friendly products by women explore impacts their personal characteristics. study was designed using two approaches: (i) an investigation into role characteristics on frequency amount spent creams; (ii) understanding check-all-that-apply (CATA) questions. Results showed that scholarity has a strong influen...

many intelligent systems are intended to communicate with users through natural language. Understanding the natural language by the computer is one of the most essential operations in natural language processing. One of the applications of natural languages is in the exams having essay questions. The objective of this paper is to propose a method for designing an examiner machine and creating a...

Purpose Self-service check-out technologies (SSTs) are becoming a trend across different retail settings, allowing companies to gain efficiency and reduce costs. Nevertheless, the success of SSTs implementation is still subject challenges uncertainties. This study aims provide insights for theory managers on necessary conditions successful SSTs. Design/methodology/approach Based an online surve...

The use of a Classroom Response System (CRS) was evaluated in two sections, A and B, of a large lecture microbiology course. In Section B the instructor used the CRS technology at the beginning of the class period posing a question on content from the previous class. Students could earn extra credit if they answered the question correctly. In Section A, the class also began with an extra credit...

When writing questions with dichotomous response options, those administering surveys on the web or on paper can choose from a variety of formats, including a check-all-that-apply or a forced-choice format (e.g. yes–no) in self-administered questionnaires. These two formats have been compared and evaluated in many experimental studies. In this paper, we conduct a systematic review and a few met...

Generally, students still need help working on story-shaped questions. This error is natural, but if it continues, will harm the mastery of next material. The ability to solve story questions closely related numeracy skills, therefore knowing location difficulties using revised Newman theorem and causal factors achieve higher learning outcomes. research was a quantitative descriptive approach, ...
