In models of visual word recognition that incorporate an interactive activation framework, activation spreads from orthographic and phonological units to semantic units and from semantic units back to phonological and orthographic units. The present research examined whether semantic feedback changes over the time course of lexical processing and as a function of stimulus quality. Using a media...

Sports videos can be characterized as a sequence of recurrent semantic story units. Storing sports videos in this story-unit-based form will lead to develop an intelligent content-based retrieval, browsing, and summarization system. The storage requires segmentation of videos and semantic understanding of each segment. Since transcribed broadcasted video speech, the closed-caption text, can be ...

In this paper, we report on our attempt at assigning semantic information from the English FrameNet to lexical units in the Bulgarian valency lexicon. The paper briefly presents the model underlying the Bulgarian FrameNet (BulFrameNet): each lexical entry consists of a lexical unit; a semantic frame from the English FrameNet, expressing abstract semantic structure; a grammatical class, defining...

The lexical component of a human language is typically heterogeneous and extremely complex. Before we can come to grips with the underlying lexical organization, we must reduce the bewildering complexity. Methods must be elaborated by which the interrelations between the units of the lexicon can be elucidated. This paper describes how a Swedish lexical material stored in a computer has been sem...

All practical scientific research and development relies inherently on a well-understood framework of quantities and units. While at first sight it appears that potential issues should by now be well understood, closer investigation reveals that there are still many potential pitfalls. There are a number of well-publicised case studies where lack of attention to units by both humans and machine...
