This paper provides an overview of a case study research that investigated the use of Digital Library (DL) resources in two undergraduate classes and explored faculty and students’ perceptions of educational digital libraries. This study found that students and faculty use academic DLs primarily for textual resources, but turn to the open Web for visual and multimedia resources. The study parti...

Semantic textual similarity is a measure of the degree of semantic equivalence between two pieces of text. We describe the SemSim system and its performance in the *SEM 2013 and SemEval-2014 tasks on semantic textual similarity. At the core of our system lies a robust distributional word similarity component that combines Latent Semantic Analysis and machine learning augmented with data from se...

Data mining algorithms such as data classification or clustering methods exploit features of entities to characterise, group or classify them according to their resemblance. In the past, many feature extraction methods focused on the analysis of numerical or categorical properties. In recent years, motivated by the success of the Information Society and the WWW, which has made available enormou...

In this paper we describe past and present work dealing with the use of textual resources, out of which semantic information can be extracted in order to provide for semantic annotation and indexing of associated image or video material. Since the emergence of semantic web technologies and resources, entities, relations and events extracted from textual resources by means of Information Extract...

This research explores the extent to which a new assessments can help students to enhance their ways of contributing to explanation-seeking discourse, and also investigates the extent to which expanding contribution repertoires helps students to advance community knowledge as a whole.

Taking this into account, the objective of contrastive parallel corpus-based study was explore way metadiscourse were used and distributed in English discourse their translation Persian language as well analyzing translation. For purpose, 30 different TED ta...

In spite of the current need in the computational community for digital corpora in different languages with complex linguistic annotations going beyond morphosyntactic features, there is not much work within the Digital Humanities community dedicated to this task. In this paper I describe recent work on the development of a bilingual (English-Spanish) corpus consisting of original comparable an...
