We present a method for determining the sentiment expressed by a customer review. The semantic orientation of a review can be positive, negative, or neutral. Our method counts positive and negative terms, but also takes into account contextual valence shifters, such as negations and intensifiers. Tests are done taking both negations and intensifiers into account, and also using only negations w...

Opinion Lexicons are linguistic resources annotated with semantic orientation of terms (positive and negative) and are important for opinion mining tasks. In the literature we see a variety of proposals for the construction of opinion lexicons using different linguistic resources and techniques. In this work, we propose and evaluate the integration of such linguistic resources to create a singl...

The article provides an insight into a problem of lexical semantic change. A short historical outline of the development of semantic studies is given. The authors analyze some of the most important stages in the history of the formation of this field. The existing approaches to dealing with form and meaning, namely semasiological and onomasiological ones are discussed. The authors consider the ...

The effectiveness of speech communication depends on the immersion in uniqueness and specificity national culture through knowledge reality. A literary text transmits background experiences, which process perception are not only interpreted by a reader, but also form value universals. Dialogue as intercultural is due to impact addressee, that is, pragmatic approach contributes to: 1) tolerance ...

1. Overview In the following we wish to highlight the design and implementation concepts of a non-standard database system (NDBS) called PRIMA and its provision for object orientation. Non-standard database applications such as CAD/CAM, VLSI design, and knowledge-based systems require adequate modeling facilities for their application objects for various reasons [H~.88b]. Data models dedicated ...

Five experiments systematically investigated whether orientation is a visual object property that aVords action. The primary aim was to establish the existence of a pure physical aVordance (PPA) of object orientation, independent of any semantic object–action associations or visually salient areas towards which visual attention might be biased. Taken together, the data from these experiments su...

This paper describes new algorithms for detecting and interpreting linear features of a real scene as imaged by a single camera on a mobile robot. The lowlevel processing stages are specifically designed to increase the usefulness and the quality of the extracted features for a semantic interpretation. The detection and interpretation processes provide a 3-D orientation hypothesis for each 2-D ...

In the context of semantic image segmentation, we show that knowledge of world-centric camera orientation (from an inertial sensor) can be used to improve classification accuracy. This works because certain structural classes (such as the ground) tend to appear in certain positions relative to the viewer. We show that orientation information is useful in conjunction with typical image-based fea...
