Expressive Power of Abstract Meaning Representations
نویسنده
چکیده
The syntax of abstract meaning representations (AMRs) can be defined recursively, and a systematic translation to first-order logic (FOL) can be specified, including a proper treatment of negation. AMRs without recurrent variables are in the decidable two-variable fragment of FOL. The current definition of AMRs has limited expressive power for universal quantification (up to one universal quantifier per sentence). A simple extension of the AMR syntax and translation to FOL provides the means to represent projection and scope phenomena.

Mental Representations of Lyrical Prose
The article analyzes mental representations of Russian lyrical prose texts. The texts demonstrate collective memory engrams that are defined by cultural and historical legacy of the nation and authors’ creative world perception. In architectonics of a lyrical prose text, sense perception reveals itself in accumulated underlying meanings and wisdom conveyed by expressive means. The author’s inte...
متن کاملThe Expressive Power of Abstract-State Machines
Conventional computation models assume symbolic representations of states and actions. Gurevich’s “Abstract-State Machine” model takes a more liberal position: Any mathematical structure may serve as a state. This results in “a computational model that is more powerful and more universal than standard computation models” [5]. We characterize the Abstract-State Machine model as a special class o...
متن کاملSemantic Parsing for Textual Entailment
In this paper we gauge the utility of general-purpose, open-domain semantic parsing for textual entailment recognition by combining graph-structured meaning representations with semantic technologies and formal reasoning tools. Our approach achieves high precision, and in two case studies we show that when reasoning over n-best analyses from the parser the performance of our system reaches stat...
متن کاملOn the Expressive Completeness of Underspecified Representations
One property of underspecified representation formalisms is that of expressive completeness, i.e. the ability to provide representations for all possibly occuring sets of readings. In this paper a general and formal definition of completeness along the lines of [6] will be given. Several formalisms will then be compared concerning their expressive power and shown to be incomplete.
متن کاملThe expressive power of analog recurrent neural networks on infinite input streams
We consider analog recurrent neural networks working on infinite input streams, provide a complete topological characterization of their expressive power, and compare it to the expressive power of classical infinite word reading abstract machines. More precisely, we consider analog recurrent neural networks as language recognizers over the Cantor space, and prove that the classes of ω-languages...
