Encyclopaedic Question Answering
Open-domain question answering (QA) is an established NLP task which enables users to search for speciVc pieces of information in large collections of texts. Instead of using keyword-based queries and a standard information retrieval engine, QA systems allow the use of natural language questions …

Context in Question Answering
Question Answering (QA) has seen a massive surge in interest, and a correlated improvement in modelperformance, over the past half decade, even surpassing humans on some datasets. Many models for this task rely on some form of contextual information that leads from the question to the answer. This …

Soft matching for question answering
… of syntactic and semantic features in current question answering (QA) systems. Such hard matching may fare poorly given variations in natural language texts. To combat such problems, I develop two soft matching schemes. I implement both soft matching schemes using statistical models and apply …

Interpretable Multi-hop Question Answering
… and challenging task of Artificial Intelligence. Question Answering (QA), an advanced form of information retrieval in the field of Natural Language Processing, aims to build a system to answer natural language questions posed by humans. Since QA tasks can be used to quantify the understanding and …

Automated Approaches to Community Question Answering
… forums, social networks, allow users to pose questions about a given topic to a community of expert users. Although successful, these applications suffer from a major drawback: it is rather complex to find similar questions with traditional keyword-based search. Thus, Community Question …

Visual question answering using external knowledge
Accurately answering a question about a given image requires combining observations with general knowledge. While this is effortless for humans, reasoning with general knowledge remains an algorithmic challenge. To advance research in this direction, a novel `fact-based' visual question answering …

Query expansion techniques for question answering
… engine, such as those commonly found in question answering (QA) systems. Common methods of query expansion for Boolean keyword-based document retrieval engines include inserting query terms, such as alternate inflectional or derivational forms generated from existing query terms, or …

Exploiting syntactic relations for question answering
… implementation of SMARTQA, a proof-of-concept question answering system that compares syntactic trees in a principled manner. Specifically, SMARTQA uses a tree edit-distance algorithm to calculate the similarity between unordered, unrooted syntactic trees. The general case of this problem is …

Utilizing the Transformer Architecture for Question Answering
The Question Answering (QA) task aims at building systems that can automatically answer a question or query about the given document(s). In this thesis, we utilize the transformer, a state-of-the-art neural architecture to study two QA problems: the answer sentence selection and the answer summary …

Syntax-based Concept Extraction For Question Answering
<p>Question answering (QA) stands squarely along the path from document retrieval to text understanding. As an area of research interest, it serves as a proving ground where strategies for document processing, knowledge representation, question analysis, and answer extraction may be evaluated in …

Clinical Question-Answering over Distributed EHR Data
… (RAG), in which an LLM is provided with both the question and context returned by an external retriever, is a promising technique for addressing the unique qualities of clinical text. LLMs using RAG can answer questions about patient records without training on privacy-sensitive data; updated …

Role of Premises in Visual Question Answering
… work, we make a simple but important observation questions about images often contain premises -- objects and relationships implied by the question -- and that reasoning about premises can help Visual Question Answering (VQA) models respond more intelligently to irrelevant or previously unseen …

Visual Question Answering in the Medical Domain
… it becomes crucial to have a reliable Visual Question Answering (VQA) system which can provide a "second opinion" on medical cases. However, most of the VQA systems that work today cater to real-world problems and are not specifically tailored for handling medical images. Moreover, the VQA …
