The Problem Of Precision In Restricted-Domain Question Answering. Some Proposed Methods Of Improvement
نویسندگان
چکیده
This paper discusses some main difficulties of restricted-domain question-answering systems, in particular the problem of precision performance. We propose methods for improving the precision, which can be classified into two main approaches: improving the Information Retrieval module, and improving its results. We present the application of these methods in a real QA system for a large company, which yielded very good results.

Presenting a method for extracting structured domain-dependent information from Farsi Web pages
Extracting structured information about entities from web texts is an important task in web mining, natural language processing, and information extraction. Information extraction is useful in many applications including search engines, question-answering systems, recommender systems, machine translation, etc. An information extraction system aims to identify the entities from the text and extr...
متن کاملHyperstability of some functional equation on restricted domain: direct and fixed point methods
The study of stability problems of functional equations was motivated by a question of S.M. Ulam asked in 1940. The first result giving answer to this question is due to D.H. Hyers. Subsequently, his result was extended and generalized in several ways.We prove some hyperstability results for the equation g(ax+by)+g(cx+dy)=Ag(x)+Bg(y)on restricted domain. Namely, we show, under some weak natural...

متن کاملUsing Terminology and a Concept Hierarchy for Restricted-Domain Question-Answering
This paper discusses an important characteristic of restricteddomain question-answering (RDQA): the issue of low precision in finding good answers. We propose methods for improving precision using domain-specific terminology and concept hierarchy to rearrange the candidate list and to better characterize the question-document relevance relationship. Once this relationship has been well establis...
متن کاملInvestigating Embedded Question Reuse in Question Answering
The investigation presented in this paper is a novel method in question answering (QA) that enables a QA system to gain performance through reuse of information in the answer to one question to answer another related question. Our analysis shows that a pair of question in a general open domain QA can have embedding relation through their mentions of noun phrase expressions. We present methods f...
