A Survey of Text Question Answering Techniques
Question Answering (QA) is a specific type of information retrieval. Given a set of documents, a Question Answering system attempts to find out the correct answer to the question pose in natural language. Question answering is multidisciplinary. It involves information technology, artificial intelligence, natural language processing, knowledge and database management and cognitive science. From...
متن کاملCore Techniques of Ontology-Based Question Answering Systems: a Survey
The Semantic Web contains an enormous amount of information in the form of ontologies. To make this information available, many ontology-based question answering (QA) systems were created in the last years. Building a QA system is difficult since many different challenges have to be solved. To address these challenges, QA systems generally combine techniques from natural language processing, ma...

متن کاملSurvey of Visual Question Answering: Datasets and Techniques
Visual question answering (or VQA) is a new and exciting problem that combines natural language processing and computer vision techniques. We present a survey of the various datasets and models that have been used to tackle this task. The first part of this survey details the various datasets for VQA and compares them along some common factors. The second part of this survey details the differe...
متن کاملQuestion Answering Evaluation Survey
Evaluating Question Answering (QA) Systems is a very complex task: state-of-the-art systems involve processing whose influences and contributions on the final result are not clear and need to be studied. We present some key points on different aspects of the QA Systems (QAS) evaluation: mainly, as performed during large-scale campaigns, but also with clues on the evaluation of QAS typical softw...
