IR-n: A Passage Retrieval System at CLEF-2001 [chapter]

Fernando Llopis, José L. Vicedo
2002 Lecture Notes in Computer Science  
This paper reports on experiments with IR-n system, a information retrieval system based on the selection of passages of variable size as basic unit of information, in the monolingual (Spanish) and bilingual  ...  Previous works showed that the use of document passages like basic unit of information, to calculate the relevance of a document to a question, improve the results of the information retrieval systems  ...  This supposes an increment of the information to store regarding those systems of information retrieval based on complete documents.  ...

Question Answering Survey: Directions, Challenges, Datasets, Evaluation Matrices [article]

Hariom A. Pandya, Brijesh S. Bhatt
2021 arXiv   pre-print
In this review work, the research directions of QA field are analyzed based on the type of question, answer type, source of evidence-answer, and modeling approach.  ...  Question answering involves but not limited to the steps like mapping of user question to pertinent query, retrieval of relevant information, finding the best suitable answer from the retrieved information  ...  Introduction Information retrieval(IR) has been an active area of research for past many decades as manual retrieval of fruitful information from enormous data is a tedious and time-consuming task.  ...

A Review of Question Answering Systems

Bolanle Ojokoh, Emmanuel Adebisi
2019 Journal of Web Engineering  
Hence, in this paper, we take a short study of the generic QA framework vis a vis Question Analysis, Passage Retrieval and Answer Extraction and some important issues associated with QA systems.  ...  We subsequently made an informed judgment of the basis for each classification criterion through literature on QA systems.  ...  Paragraph Retrieval Module Passage retrieval is naturally based on an orthodox search engine to retrieve a set of significant candidate passages or sentences from a knowledge base.  ...

A New Question Answering System for the Arabic Language

Ghassan Kanaan, Awni Hammouri, Riyad Al-Shalabi, Majdi Swalha
2009 American Journal of Applied Sciences  
In order to handle this problem, traditional information retrieval techniques joined with a sophisticated natural language processing approach have been used in this research work.  ...  The system differs from most question answering systems in its dependency on data redundancy rather than complicated linguistic analyses of either questions or contender answers.  ...  ACKNOWLEDGMENT The authors would like to thank Professor Martha Evens from Illinois Institute of Technology for her helpful comments and suggestions that reflected many improvements in the presentation  ...

An analysis of two approaches in information retrieval: From frameworks to study designs

Kalervo Järvelin
2007 Journal of the American Society for Information Science and Technology
