Answer Extraction Using a Dependency Grammar in Extrans
نویسندگان
چکیده
Nous exposons ici l’implémentation d’un système d’extraction de réponses, ExtrAns, qui utilise la sortie d’un analyseur et d’une grammaire basés sur les dépendances. Afin d’augmenter la vitesse de calcul, l’analyseur et la grammaire utilisés sacrifient le fonctionnalisme (dans le cadre des grammaires de dépendance) au profit de la projectivité. Nous avons découvert que les structures de dépendance résultantes, bien qu’elles soient difficiles à traiter, peuvent être utilisées par ExtrAns pour trouver les dépendances syntaxiques et sémantiques nécessaires dans plusieurs des étapes du traitement linguistique. En particulier, nous mettons l’accent sur la génération de formes logiques minimales.

Dependency-Based Semantic Interpretation for Answer Extraction
This paper focuses on the use of two algorithms for the integration of two broad-coverage dependency-based parsing systems into ExtrAns, an answer extraction system that operates over Unix manual pages. In the process, ExtrAns uses a semantic interpreter that converts the output of the parser into flat logical forms. The semantic interpreter for the first parsing system, Link Grammar, uses a to...
متن کاملFrom Minimal Logical Forms for Answer Extraction to Logical Graphs for Question Answering
Many exciting things happened since I left the ExtrAns project at the University of Zurich. In this paper I present a very brief journal of the research that derived from my work at Zurich. My work combined a study of several representations of questions and answer sentences with the development of procedures to find the answer. The culmination of this work was the definition of the Logical Gra...
متن کاملExtrAns Answer Extraction from Technical Documents by Minimal Logical Forms and Selective Highlighting
Logic-based answer extraction techniques present a solution to retrieve and mark those exact passages in a document that directly answer a natural language query. In contrast to pure information retrieval techniques that treat content words as isolated terms, answer extraction techniques exploit syntactic information in a document to a certain degree and consider semantic relations between func...
متن کاملA Real World Implementation of Answer Extraction
In this paper we describe ExtrAns, an answer extraction system. Answer extraction (AE) aims at retrieving those exact passages of a document that directly answer a given user question. AE is more ambitious than information retrieval and information extraction in that the retrieval results are phrases, not entire documents, and in that the queries may be arbitrarily specific. It is less ambitiou...
متن کاملA Novel Approach to Conditional Random Field-based Named Entity Recognition using Persian Specific Features
Named Entity Recognition is an information extraction technique that identifies name entities in a text. Three popular methods have been conventionally used namely: rule-based, machine-learning-based and hybrid of them to extract named entities from a text. Machine-learning-based methods have good performance in the Persian language if they are trained with good features. To get good performanc...
