This paper presents results from lesion experiments on a modular attractor neural network model of semantic access. Real picture data forms the basis of perceptual input to the model. An ultrametric attractor space is used to represent semantic memory and is implemented using a biologically plausible variant of the Hopfield model. Lesioned performance is observed to be in agreement with neurops...

Semantic representation is receiving growing attention in NLP in the past few years, and many proposals for semantic schemes (e.g., AMR, UCCA, GMB, UDS) have been put forth. Yet, little has been done to assess the achievements and the shortcomings of these new contenders, compare them with syntactic schemes, and clarify the general goals of research on semantic representation. We address these ...

We present a method for automatically creating large-scale semantic networks from natural language text, based on deep semantic analysis. We provide a robust and scalable implementation, and sketch various ways in which the representation may be deployed for conceptual knowledge acquisition. A translation to RDF establishes interoperability with a wide range of standardised tools, and bridges t...

Semantic strategies are a kind of discourse strategy that include the sum of language and cognitive moves which are used to reach an adequate goal of communication normally resulting in text comprehension by the reader or listener. Here, the language user takes a number of steps in order to perform a complex task. Semantic strategies in prejudiced talk have been examined extensively in western ...

terrorism is regarded as among the current issues discussed in the international community. it has particularly attracted the attention of people all over the world, both in the east and the west, after the events of september 11, 2001. however, there is no consensus in determining its semantic framework, with each definition admitting to this terms’ relativity. our religion, nevertheless, is a...

Despite advances in computer technology, terminologists still tend to rely on manual work to extract all the semantic information that they need for the description of specialized concepts. In this paper we propose the creation of new word sketches in Sketch Engine for the extraction of semantic relations. Following a pattern-based approach, new sketch grammars are developed in order to extract...

Recent work in the field of middleware technology proposes semantic spaces as a tool for coping with the scalability, heterogeneity and dynamism issues of large scale distributed IT environments. In this paper we discuss the impact that functional and non-functional requirements have on the scalability of a semantic space installation. Based on this analysis we elaborate on the application scen...
