2002 Text Retrieval Conference  
As a foundation for targeting complex questions involving opinions, events, and paragraph-length answers, we recently built two systems for answering short factual questions.  ...  We conclude by discussing current work aiming at combining modules from the two systems in a unified, more accurate system and adding capabilities for producing complex answers in addition to short ones  ...  We would like to thank Ralph Weischedel of BBN Systems and Technologies for giving us the named entity tagger (Identifinder), and Daniel Gildea for the FrameNet parser.  ...

AQA-WebCorp: Web-based Factual Questions for Arabic

Wided Bakari, Patrice Bellot, Mahmoud Neji
2016 Procedia Computer Science  
We present a method for recovering text passages. This method is based on a real automatic interrogation of Google, in order to generate passages of texts and answer the factual questions.  ...  As well as, Arabic doesn't have an equivalent number of linguistic corpuses as compared to other languages like English. In this paper, we focus on building our corpus of Arab questions-texts.  ...  Acknowledgements I give my sincere thanks for my collaborators Professor Patrice BELLOT (University of Aix Marseille, France) and Mr.  ...

Natural Language Interfaces to Data

Abdul Quamar, Vasilis Efthymiou, Chuan Lei, Fatma Özcan
2022 Foundations and Trends in Databases  
There are two main approaches in the literature for interpreting a user's natural language query. Rule-based systems make use of semantic indices, ontologies, and knowledge  ...  While early systems evolved from keyword search and focused on simple factual queries, the complexity of both the input sentences as well as the generated SQL queries has evolved over time.  ...  Instead of a simple keyword search over the data, question answering systems can provide more meaningful and insightful information in the form of short answers to the user's natural language questions  ...

Mendel Actually Wants to Say: Genes Are Only One Element of the Hereditary Material

Muying Zhou
2018 OALib  
It means that genes are not a producer. This compels us to review Mendel's experiments and the original meaning of genes.  ...  The template has the controlling product's specifications, which guide the operator to produce an individual that conforms to its given specifications. The template cannot produce the individual.  ...  Acknowledgements We thank Lesley Benyon, PhD, from Liwen Bianji, Edanz Group China (http://www.liwenbianji.cn/ac), for editing the English text of a draft of this manuscript.  ...

Question temporality

Aditya Pal, James Margatan, Joseph Konstan
2012 Proceedings of the ACM 2012 conference on Computer Supported Cooperative Work - CSCW '12  
Our research can be instructive for interface designers to design temporality-aware interfaces and influence selection of questions and answers for display.  ...  In this paper, we introduce the concept of question temporality as a measure of the usefulness of the answers provided on the questions asked in the Question Answering sites (QA).  ...  ACKNOWLEDGEMENT We would like to thank the anonymous reviewers for providing their valuable feedback.  ...

QAFactEval: Improved QA-Based Factual Consistency Evaluation for Summarization [article]

Alexander R. Fabbri, Chien-Sheng Wu, Wenhao Liu, Caiming Xiong
2022 arXiv   pre-print
Building on those insights, we propose an optimized metric, which we call QAFactEval, that leads to a 14% average improvement over previous QA-based metrics on the SummaC factual consistency benchmark,  ...  In this work, we conduct an extensive comparison of entailment and QA-based metrics, demonstrating that carefully choosing the components of a QA-based metric, especially question generation and answerability  ...  We believe that our work lays the foundation for future work in QA-based metrics for factual consistency by offering a fairer comparison to other metrics across datasets and settings.  ...
