Recent years have seen increasing research on extracting and using temporal information in natural language applications. However most of the works found in the literature have focused on identifying and understanding temporal expressions in newswire texts. In this paper we report our work on anchoring temporal expressions in a novel genre, emails. The highly under-specified nature of these exp...

Handling temporal information has been a main concern of areas such as natural language processing planning and knowledge repre sentation In scheduling dialogues temporal reference is central and the relations between temporal expressions contain much of the ellip sis and anaphora to be resolved As a consequence lling in missing information contributes to the understanding of the text In this p...

The German question answering (QA) system InSicht participated in QA@CLEF for the third time. InSicht realizes a deep QA approach: it builds on full sentence parses, inferences on semantic representations, and matching between semantic representations derived from questions and document sentences. InSicht was improved for QA@CLEF 2006 in the following main areas: temporal expressions are better...

The paper describes the main steps for the construction, annotation and validation of the Romanian version of the TimeBank corpus. Starting from the English TimeBank corpus – the reference annotated corpus in the temporal domain, we have translated all the 183 English news texts into Romanian and mapped the English annotations onto Romanian, with a success rate of 96.53%. Based on ISO-Time the ...

People use spatial metaphors to talk about temporal concepts. They also gesture frequently during speech. The characteristics of these gestures give information regarding the mental timelines people form to experience time. The present study investigates the expression of temporal concepts on a natural setting with Turkish speakers. We found that Turkish speakers used more metaphoric temporal p...

This paper presents the methodology and results of a project for the large-scale analysis of public messages in political discourse on Facebook, the dominant social media site in Hungary. We propose several novel social psychologymotivated dimensions for natural language processing-based text analysis that go beyond the standard sentiment-based analysis approaches. Communion describes the moral...

In this paper we present the DANTE system, a tagger for temporal expressions in English documents. DANTE performs both recognition and normalization of the expressions in accordance with the TIMEX2 annotation standard. The system is built on modular principles, with a clear separation between the recognition and normalisation components. The interface between these components is based on our no...

Suregen-2 applications are intended for use as add-on modules for clinical information systems. Currently, Suregen-2 permits refinement of the predefined medical ontology, specification of text plans and description knowledge for objects of the ontology. It has built-in constructs for referential expressions, aggregation, enumeration and recurrent semantic constellations. A first application bu...

We derive analytical expressions of local codimension-1 bifurcations for a fully connected, additive, discrete-time recurrent neural network (RNN), where we regard the external inputs as bifurcation parameters. The complexity of the bifurcation diagrams obtained increases exponentially with the number of neurons. We show that a three-neuron cascaded network can serve as a universal oscillator, ...

As an extension of the discrete-time case, this note investigates the variance of the total cumulative reward for the embedded Markov chain of semi-Markov processes. Under the assumption that the chain is aperiodic and contains a single class of recurrent states recursive formulae for the variance are obtained which show that the variance growth rate is asymptotically linear in time. Expression...
