What does a conditional knowledge base entail? [article]

Daniel Lehmann, Menachem Magidor
2002 arXiv   pre-print
We look for a plausible definition of the set of all conditional assertions entailed by a conditional knowledge base. In a previous paper, S.  ...  A conditional knowledge base, consisting of a set of conditional assertions of the type "if ... then ...  ...  The fundamental question studied in this paper is the following: given a knowledge base K, what are the conditional assertions that should be considered as entailed, i.e., logically implied, by K?  ...

'Knows' Entails Truth

Michael Hannon
2013 Journal of Philosophical Research (JPR)  
In a recent article, Allan Hazlett argues that our ordinary concept of knowledge is not factive.  ...  From this it seems to follow that epistemologists cannot appeal to ordinary language to justify the truth condition of knowledge.  ...  Even philosophers who think that knowledge cannot be analysed in terms of necessary and sufficient conditions agree that knowledge entails truth (e.g. Williamson 2000: 42) .  ...

Does Knowledge Entail Belief?

Masaharu Mizumoto
2008 Kagaku tetsugaku  
The "entailment thesis", or the principle that knowledge entails belief, is accepted by most epistemologists today. However, not everyone agrees.  ...  belief or knowledge 3) a premise in practical reasoning and re-define the original criterion in the form of a necessary condition as: One has memory-based propositional knowledge only when he possesses  ...  (knowledge as competence). Either case, therefore, does not stand as a counterexample to the entailment thesis, that knowledge entails belief.  ...

Defining textual entailment

Daniel Z. Korman, Eric Mack, Jacob Jett, Allen H. Renear
2018 Journal of the Association for Information Science and Technology  
Much ingenuity has been devoted to developing algorithms for identifying textual entailments, but relatively little to saying what textual entailment actually is.  ...  Textual entailment is a relationship that obtains between fragments of text when one fragment in some sense implies the other fragment.  ...  Acknowledgments We acknowledge the contributions by David Dubin, Catherine Blake, and Henry A.  ...

Generalized Entailments

Andrzej Wiśniewski
2017 Logic and Logical Philosophy  
Entailment understood in the standard way exhibits a kind of asymmetry: what is entailed is a single wff, while what is entailing it is a set of wffs.  ...  What 'must' means here depends on a logic under consideration, and similarly for 'truth.'  ...  This work was supported by funds of the National Science Centre, Poland (DEC-2012/04/A/HS1/00715).  ...

Does Perceiving Entail Knowing?

JOHN TURRI
2010 Theoria  
First, it refutes an influential view about the relationship between perception and knowledge. In particular, it demonstrates that perceiving does not entail knowing.  ...  Second, it leverages that refutation to demonstrate that knowledge is not the most general factive propositional attitude.  ...  Since (1) P entails R, but (2) S does not entail R, it follows that (3) S does not entail P. 3 Radford 1966 dissents.  ...

Knowledge entails dispositional belief

their respondents had intuitions conforming to the view that knowledge does not entail belief.  ...  So runs the leading challenge to the orthodox view that knowledge entails belief.  ...  Johnston gives the example of a fragile glass which is struck (triggering condition) but does not shatter (no manifestation) due to careful packaging (the mask).  ...

XTE: Explainable Text Entailment [article]

Vivian S. Silva, André Freitas, Siegfried Handschuh
2020 arXiv   pre-print
Furthermore, for entailments requiring world knowledge, most systems still work as a "black box", providing a yes/no answer that does not explain the underlying reasoning process.  ...  Also, if a semantic matching is involved, we make the answer interpretable, using external knowledge bases composed of structured lexical definitions to generate natural language justifications that explain  ...  For semantic entailments, we look for the semantic relationships holding between T and H, employing a distributional (word embedding-based) navigation algorithm that explores a graph knowledge base composed  ...

Necessity, Entailment, Shared Agonism

Dominic Smith
2021 Foundations of Science  
I argue that the contingency of our contemporary sense of the transcendental can be precisely what makes it valuable.  ...  AbstractThis short paper offers a series of responses to Jochem Zwier and Timothy Barker's comments on my extended paper 'Taking Exception: Philosophy of Technology as a Multidimensional Problem Space.  ...  Although this point is exaggerated, there is, I think, more than a grain of truth to it. 3 2 Entailment Zwier's second big question is: 'what does Smith's renewal of the transcendental imply and entail  ...

Entailment among Probabilistic Implications

Albert Atserias, Jose L. Balcazar
2015 2015 30th Annual ACM/IEEE Symposium on Logic in Computer Science  
Its formulas are pairs of conjunctions of positive literals, related together by an implicational-like connective; the semantics of this sort of implication is defined in terms of a threshold on a conditional  ...  By exploiting a previously noted alternative view of this entailment in terms of linear programming duality, we characterize exactly the cases of entailment from arbitrary numbers of premises.  ...  But when these necessary conditions for proper entailment are disjuncted with the necessary and sufficient conditions for improper entailment, what results is an if and only if characterization of entailment  ...

From Building Corpora for Recognizing Faceted Entailment to Recognizing Relational Entailment

Martin Víta
2018 Position Papers of the 2018 Federated Conference on Computer Science and Information Systems  
Recognizing textual entailment (RTE) became a well established and widely studied task.  ...  In this paper, we present a semi-automatic approach to deriving corpora for faceted entailment task from a general RTE corpus using open information extraction (open IE) tools.  ...  Next, probably more important application of recognizing relational entailment, arise from checking/proving facts in open knowledge bases, i. e., in knowledge bases that consist of open IE tuples.  ...

Temporal and Aspectual Entailment [article]

In this paper we propose a novel entailment dataset and analyse the ability of a range of recently proposed NLP models to perform inference on temporal predications.  ...  We show that the models encode a substantial amount of morphosyntactic information relating to tense and aspect, but fail to model inferences that require reasoning with these semantic properties.  ...  This research was supported in part by ERC Advanced Fellowship GA 742137 SE-MANTAX, a Google faculty award, a Bloomberg L.P.  ...

The paper presents a rule-based system for paraphrasing and textual entailment generation in Czech.  ...  The transformations make use of several language resources as well as a natural language generation (NLG) subsystem. The paraphrases and entailments are annotated by one or more annotators.  ...  -EDITS (Edit Distance Textual Entailment Suite) 7 is a RTE software based on edit distance.  ...
