A parallel system for text inference using marker propagations

TLDR
This paper presents a possible solution for the text inference problem-extracting information unstated in a text, but implied that takes advantage of a semantic English dictionary available in electronic form that provides the basis for the development of a large linguistic knowledge base.
Abstract
This paper presents a possible solution for the text inference problem-extracting information unstated in a text, but implied. Text inference is central to natural language applications such as information extraction and dissemination, text understanding, summarization, and translation. Our solution takes advantage of a semantic English dictionary available in electronic form that provides the basis for the development of a large linguistic knowledge base. The inference algorithm consists of a set of highly parallel search methods that, when applied to the knowledge base, find contexts in which sentences are interpreted. These contexts reveal information relevant to the text. Implementation, results, and parallelism analysis are discussed.

Lexical chains for question answering

TL;DR: Topical relations expressed as lexical chains on extended WordNet improve the performance of a question answering system by increasing the document retrieval recall and by providing the much needed axioms that link question keywords with answers.

An interactive tool for the rapid development of knowledge bases

TL;DR: It is widely accepted that more knowledge means more intelligence, but in many knowledge intensive applications, it is necessary to have extensive domain-specific knowledge in addition to general-purpose knowledge.

Chapter 20 Knowledge Representation and Question Answering

TL;DR: Question answering takes a whole new dimension where the system has a huge body of documents, and it is asked a query in a natural language, and the system is expected to give an answer to the question not only using the documents but also using appropriate commonsense knowledge.
