Counting Answers to Existential Questions [article]

Holger Dell, Marc Roth, Philip Wellnitz
2019 arXiv   pre-print
If the dominating star size of a conjunctive query is large, then we show that counting solution tuples to the query is at least as hard as counting dominating sets, which yields a fine-grained complexity  ...  Using ideas stemming from Lov\'asz, we lift complexity results from the class of conjunctive queries to arbitrary existential or universal formulas that might contain inequalities and negations on constraints  ...  In particular, we are very grateful to Joshua and Daniel for pointing out the reference [31] .  ...

Has not psychoanalysis taught us to answer this question with great circumspection? In this predicament existentialism offers us still another, a third way.  ...  Existentialism answers this question in the unexpected sense that it denies any substance underlying accidents in man.  ...

Natural Answer Generation: From Factoid Answer to Full-length Answer using Grammar Correction [article]

Manas Jain, Sriparna Saha, Pushpak Bhattacharyya, Gladvin Chinnadurai, Manish Kumar Vatsa
2021 arXiv   pre-print
Question Answering systems these days typically use template-based language generation.  ...  We compare our system with (i) Modified Pointer Generator (SOTA) and (ii) Fine-tuned DialoGPT for factoid questions. We also test our approach on existential (yes-no) questions with better results.  ...  We present a rule based approach for existential questions (Yes/No questions) where Yes/No is considered as the factoid answer and natural answer is generated by rearranging noun phrase and verb phrase  ...

Approximating Givenness in Content Assessment through Distributional Semantics

Ramon Ziai, Kordula De Kuthy, Detmar Meurers
2016 Proceedings of the Fifth Joint Conference on Lexical and Computational Semantics  
Current approaches only implement a very basic, surface-based perspective on Givenness: A word of the answer that appears as such in the question counts as GIVEN.  ...  As experimental testbed, we focus on short answer assessment, in which the goal is to assess whether a student response correctly answers the provided reading comprehension question or not.  ...  Acknowledgments We would like to thank Mohamed Balabel for his work on training and selecting the distributional model.  ...

Stop beating the donkey! A fresh interpretation of conditional donkey sentences

María José Frápolli, Aránzazu San Ginés
2017 THEORIA : an International Journal for Theory, History and Fundations of Science  
We propose a new approach to conditional donkey sentences that allows us to face successfully the often called proportion problem.  ...  The main ingredients of the proposal are van Benthem's generalized quantifier approach to conditionals (van Benthem, 1984), and Barwise's situation semantics (Barwise, 1989).  ...  YES NO THE RESULTS Context and question 1: Context and question 2: Answer to question 1: NO Answer to question 2: YES 1 6 Answer to question 1: NO Answer to question 2: NO 5 5 Observation: In our experiment  ...
