Linguistic Knowledge And Question Answering
نویسنده
چکیده
The availability of robust and deep syntactic parsing can improve the performance of all modules of a Question Answering system. In this article, this is illustrated using examples from our QA system Joost, a Dutch QA system which has been used for both open and closed domain QA. The system can make use of information found in the fully parsed version of the document collections. We demonstrate that this improves the performance of various components of the system, such as answer extraction and selection, lexical acquisition, off-line relation extraction, and passage retrieval. RÉSUMÉ. Une analyse syntaxique profonde et robuste améliore la performance d’un système de question-réponse. Dans cet article, nous le montrerons en donnant des exemples de notre système QR, appelé Joost. C’est un système néerlandais, qui a été appliqué au domaine général ainsi qu’au domaine restreint. Le système utilise l’information contenue dans une version analysée syntaxiquement du corpus des documents. Nous montrerons que l’utilisation de l’information syntaxique améliore certains modules de Joost, comme l’extraction et l’ordonnancement final des réponses, l’acquisition automatique d’information lexicale, l’extraction de faits hors ligne et la recherche de passages.

Examining the Role of Statistical and Linguistic Knowledge Sources in a General-Knowledge Question-Answering System
We describe and evaluate an implemented system for general-knowledge question answering. The system combines techniques for standard ad-hoc information retrieval (IR), query-dependent text summarization, and shallow syntactic and semantic sentence analysis. In a series of experiments we examine the role of each statistical and linguistic knowledge source in the question-answering system. In con...
متن کاملHybridization in Question Answering Systems
Question answering systems can benefit from the incorporation of a broad range of technologies, including natural language processing, machine learning, information retrieval, knowledge representation, and automated reasoning. We have designed an architecture that identifies the essential roles of components in a question answering system. This architecture greatly facilitates experimentation b...
متن کاملKnowledge Tracking: Answering Implicit Questions
Research on Question Answering has produced an arsenal of useful techniques for detecting answers that are explicitly present in the text of a collection of documents. To move beyond current capabilities, effort must be directed toward analyzing the source documents and interpreting them by representing their content, abstracting away from the particular linguistic expressions used. The content...
متن کاملIntegrating Linguistic Knowledge in Passage Retrieval for Question Answering
In this paper we investigate the use of linguistic knowledge in passage retrieval as part of an open-domain question answering system. We use annotation produced by a deep syntactic dependency parser for Dutch, Alpino, to extract various kinds of linguistic features and syntactic units to be included in a multi-layer index. Similar annotation is produced for natural language questions to be ans...
متن کاملLogAnswer - A Deduction-Based Question Answering System
LogAnswer is an open domain question answering system which employs an automated theorem prover to infer correct replies to natural language questions. For this purpose LogAnswer operates on a large axiom set in first-order logic, representing a formalized semantic network acquired from extensive textual knowledge bases. While other work in the field of question answering focuses on shallow lin...
متن کاملOganizing Encyclopedic Knowledge based on the Web and its Application to Question Answering
We propose a method to generate large-scale encyclopedic knowledge, which is valuable for much NLP research, based on the Web. We first search the Web for pages containing a term in question. Then we use linguistic patterns and HTML structures to extract text fragments describing the term. Finally, we organize extracted term descriptions based on word senses and domains. In addition, we apply a...
