In this paper we examine the influence of dimensionality on natural language route directions in dialogue. Specifically, we show that giving route instructions in a quasi-3d environment leads to experiential descriptive accounts, as manifested by a higher proportion of location descriptions, lack of chunking, use of 1st person singular personal pronouns, and more frequent use of temporal and sp...

This paper describes the approach of the system that we built as part of the participation in ‘PAN 2015 Source Retrieval’ task. Chunking of documents based on paragraphs and efficient download filtering improved the overall performance of the system. Source Retrieval is an important task of a Plagiarism Detection system

Our approach for unsupervised extraction of prosodic structure in spontaneous speech consists of the four steps: chunking into interpausal units, syllable nucleus extraction, prosodic boundary detection, and pitch accent detection. The extraction is based on acoustic features derived from F0 parameterization, and on energy and segment duration features. Phrase boundaries and accents are detecte...

Significant amount of work has been devoted recently to develop learning techniques that can be used to generate partial (shallow) analysis of natural language sentences rather than a full parse. In this work we set out to evaluate whether this direction is worthwhile by comparing a learned shallow parser to one of the best learned full parsers on tasks both can perform — identifying phrases in...

The Indian Ocean tsunami of 26 December 2004 was one of the greatest natural disasters; it was also the first internet-mediated natural disaster. Despite the presumed ubiquity and power of advanced technologies including satellites and the internet, no advance warning was given to the affected coastal populations by their governments or others. This article examines the conditions for the suppl...

In this study, dynamic bearing capacity of adjacent shallow strip foundations located on sandy soil was examined using a numerical finite difference modeling, FLAC. The behavioral interference of shallow strip foundations under different conditions was investigated. The effect of soil strength parameters, geometric characteristics of shallow foundations and cyclic loads at different distance ra...

The studied area includes Sulaimani, Erbil and Dohuk Governorates where Cretaceous rocks are well exposed in the High Folded Zone of North and Northeastern Iraq. This area is part of the northwestern boundary of Arabian platform near to Iranian border. In these governorates, the study tries to clarify the relations between deep and shallow stratigraphic units (formation or facies) during Cretac...

The extraction of the keywords that characterize each document in a given collection is one of the most important components of an Information Retrieval system. In this article, we propose to apply shallow parsing, implemented by means of cascades of finite-state transducers, to extract complex index terms based on an approximate grammar of Spanish. The effectiveness of the index terms extracte...
