The current study evaluated the effects of conditional discrimination (listener) training with coins on the emergence of novel stimulus relations, textual behavior, tacts, and intraverbals. Two preschoolers with autism were taught 3 relations among coins, their names, and values. After initial training, 4 relations emerged for the first participant and 7 for the second participant, suggesting t...

This paper presents a commercial shot classification scheme combining well-designed visual and textual features to automatically detect TV commercials. To identify the inherent difference between commercials and general programs, a special mid-level textual descriptor is proposed, aiming to capture the spatio-temporal properties of the video texts typical of commercials. In addition, we introdu...

This paper presents an approach to computer-assisted teaching of reading abilities using corpus data. The approach is supported by a set of tools for automatically selecting and classifying texts retrieved from the Internet. The approach is based on a linguistic model of textual cohesion which describes relations between larger textual units that go beyond the sentence level. We show that textu...

We present a Textual Entailment (TE) recognition system that uses semantic features based on the Universal Networking Language (UNL). The proposed TE system compares the UNL relations in both the text and the hypothesis to arrive at the two-way entailment decision. The system has been separately trained on each development corpus released as part of the Recognizing Textual Entailment (RTE) comp...

In the logic approach to Recognizing Textual Entailment, identifying phrase-tophrase semantic relations is still an unsolved problem. Resources such as the Paraphrase Database offer limited coverage despite their large size whereas unsupervised distributional models of meaning often fail to recognize phrasal entailments. We propose to map phrases to their visual denotations and compare their me...

This paper describes the experiments developed and the results obtained in the participation of UNED in the Third Recognising Textual Entailment (RTE) Challenge. The experiments are focused on the study of the effect of named entities in the recognition of textual entailment. While Named Entity Recognition (NER) provides remarkable results (accuracy over 70%) for RTE on QA task, IE task require...

On the text surface the transition from one communicative goal to another can, for instance , be observed from the text layout. Where a new goal sets in, the p;i.ragral)h structure is often interrupted and a new paragraph begins. Also, the theme of the first sentence of such a new paragraph is in inost ca.ses not related to any element in the previous sentence, which is the case when subsequent...
