Question answering from the web using knowledge annotation and knowledge mining techniques

Jimmy Lin, Boris Katz
2003 Proceedings of the twelfth international conference on Information and knowledge management - CIKM '03  
We present a strategy for answering fact-based natural language questions that is guided by a characterization of realworld user queries.  ...  Our approach, implemented in a system called Aranea, extracts answers from the Web using two different techniques: knowledge annotation and knowledge mining.  ...  This technique is a simplified implementation of the technologies pioneered by Start [15] and Omnibase [16] , two components of the world's first Web-based question answering system.  ...

A logical representation of Arabic questions toward automatic passage extraction from the Web

Wided Bakari, Patrice Bellot, Mahmoud Neji
2017 International Journal of Speech Technology  
With the expanding growth of Arabic electronic data on the web, extracting information, which is actually one of the major challenges of the question-answering, is essentially used for building corpus  ...  In this paper, we propose a method to analysis the question and retrieve the passage answer in the Arabic language. For the question analysis, five factual question types are processed.  ...  Figure 2: Source of the questions used for our corpus The data collected from the web about the questions and the texts will help us to build an extensible corpus for Arabic question-answering.  ...

Versatile question answering systems: seeing in synthesis

Sparsh Mittal, Ankush Mittal
2011 International Journal of Intelligent Information and Database Systems  
The complex questions appearing in real-life generally require multiple techniques or sub-division of question at various levels. Several practical systems have been developed to explore this.  ...  Recent advances in massive information storage and growth of internet have led to increased necessity of tools such as search engines and QA systems to get meaningful answers from the vast amount of information  ...  Techniques to answer validation range from purely statistical methods based on web search to the use of semantic techniques (Harabagiu and Maiorano, 1999) .  ...
