Neural Activation Semantic Models: Computational lexical semantic models of localized neural activations

1 code implementation COLING 2018 Nikos Athanasiou, Elias Iosif, Alex Potamianos, ros

Neural activation models have been proposed in the literature that use a set of example words for which fMRI measurements are available in order to find a mapping between word semantics and localized neural activations.

Crossmodal Network-Based Distributional Semantic Models

no code implementations LREC 2016 Elias Iosif, Alex Potamianos, ros

Despite the recent success of distributional semantic models (DSMs) in various semantic tasks they remain disconnected with real-world perceptual cues since they typically rely on linguistic features.

Cognitively Motivated Distributional Representations of Meaning

no code implementations LREC 2016 Elias Iosif, Spiros Georgiladakis, Alex Potamianos, ros

Although meaning is at the core of human cognition, state-of-the-art distributional semantic models (DSMs) are often agnostic to the findings in the area of semantic cognition.

Word Semantic Similarity for Morphologically Rich Languages

no code implementations LREC 2014 Kalliopi Zervanou, Elias Iosif, Alex Potamianos, ros

In this work, we investigate the role of morphology on the performance of semantic similarity for morphologically rich languages, such as German and Greek.

Associative and Semantic Features Extracted From Web-Harvested Corpora

no code implementations LREC 2012 Elias Iosif, Maria Giannoudaki, Eric Fosler-Lussier, Alex Potamianos, ros

We address the problem of automatic classification of associative and semantic relations between words, and particularly those that hold between nouns.
