Rethinking the Objectives of Extractive Question Answering [article]

Martin Fajcik, Josef Jon, Pavel Smrz
2021 arXiv   pre-print
Among those, we propose a compound objective, composed from the joint probability while still keeping the objective with independence assumption as an auxiliary objective.  ...  This work demonstrates that using the objective with independence assumption for modelling the span probability P(a_s,a_e) = P(a_s)P(a_e) of span starting at position a_s and ending at position a_e has  ...  question-passage-answer triplet (q, D, a) from dataset D.  ...

Pre-nosology diagnostics

Roman М. Baevsky, Azalia P. Berseneva
2017 Cardiometry  
Author contributions The authors read the ICMJE criteria for authorship and approved the final manuscript.  ...  Filling out the questionnaire also is not a problem. The questionnaire must contain no more than 15-20 questions with multiple choice answers.  ...  Another argument for the choice is that DT is a key parameter in pre-nosology diagnostics, as it can be measured using a comparatively simple and proven method of heart rate variabil- LF = FR · DT. ity  ...

NLog-like Inference and Commonsense Reasoning

Lenhart Schubert
2014 Linguistic Issues in Language Technology  
Recent implementations of Natural Logic (NLog) have shown that NLog provides a quite direct means of going from sentences in ordinary language to many of the obvious entailments of those sentences.  ...  We show here that Episodic Logic (EL) and its Epilog implementation are well-adapted to capturing NLog-like inferences, but beyond that, also support inferences that require a combination of lexical knowledge  ...  The paper owes its existence to the organization of the LSA Workshop on Semantics for Textual Inference and follow-up work by Cleo Condoravdi and Annie Zaenen, and benefited from their editorial comments  ...
