Exemplar-based pitch accent categorisation using the generalized context model

This paper presents the results of a pitch accent categorisation simulation which attempts to classify L*H and H*L accents using a psychologically motivated exemplar-theoretic model of categorisation. Pitch accents are represented in terms of six linguistically meaningful parameters describing their shape. No additional information is employed in the categorisation process. The results indicate...

Interplay between semantic and emotional information in visual scene processing

We examined whether and how image’s semantics and emotion content interact during visual processing. In each trial, we briefly presented two emotional or neutral images (a scene context and an object), manipulating the semantic consistency and the emotional consistency of the pair. Participants categorised one image semantically or emotionally. Semantic categorisation was overall better than em...

Categorisation by Context

Assistance in retrieving of documents on the World Wide Web is provided either by search engines, through keyword based queries, or by catalogues, which organise documents into hierarchical collections. Maintaining catalogues manually is becoming increasingly difficult due to the sheer amount of material, and therefore it will be necessary to resort to techniques for automatic classification of...

The Role of Automated Categorisation in e-Government Information Retrieval

High-precision search results are essential for supporting e-government employees’ information tasks. Prior studies have shown that existing features of e-government retrieval systems need improvement in terms of search facilities, navigation and metadata. This paper investigates how automated categorisation can enhance information organisation and retrieval and presents the results of a realis...
