In this paper we argue that a clear division between two sources of information— one oriented to world knowledge, the other to linguistic semantics—offers a framework within which mechanisms for modelling the highly flexible relation between language and interpretation necessary for natural discourse can be specified and empirically validated. Moreover, importing techniques and results from for...

Full discourse parsing in the PDTB framework is a task that has only recently been attempted. We present the Two Taggers approach, which reformulates the discourse parsing task as two simpler tagging tasks: identifying the relation within each sentence, and identifying the relation between each pair of adjacent sentences. We then describe a system that uses two CRFs to achieve an F1 score of 39...

We describe our experiments on evaluating recently proposed modifications to the discourse relation annotation scheme of the Penn Discourse Treebank (PDTB), in the context of annotating discourse relations in Hindi Discourse Relation Bank (HDRB). While the proposed modifications were driven by the desire to introduce greater conceptual clarity in the PDTB scheme and to facilitate better annotat...

Discourse parsing is the process of discovering the latent relational structure of a long form piece of text and remains a significant open challenge. One of the most difficult tasks in discourse parsing is the classification of implicit discourse relations. Most state-of-the-art systems do not leverage the great volume of unlabeled text available on the web–they rely instead on human annotated...

Varvarigos, E.A. and D.P. Bertsekas, Communication algorithms for isotropic tasks in hypercubes and wraparound meshes, Parallel Computing 18 (1992) 1233-1257. We consider a broad class of communication tasks, which we call isotropic, in a hypercube and in a wraparound mesh of processors. These tasks are characterized by a type of symmetry with respect to origin node. We show that executing such...

The present research aimed at investigating the interaction of the classroom talk to have a better understanding of the teachers’ practice teaching which can pave the way for reflection on teaching. The study benefitted from conversation analytic perspective to qualitatively and interpretively examine the classroom discourse of the teacher-learner interaction. The classroom talk was analyzed th...

OBJECTIVE To investigate the cognitive and neural correlates of discourse impairment in corticobasal syndrome (CBS). BACKGROUND Difficulty communicating is a frequent clinical manifestation in patients with CBS. However, the mechanisms underlying this disabling problem are not well understood. METHODS Twenty patients with CBS and 8 healthy seniors narrated a picture story. Narratives were a...

We are interested in scheduling tasks from several selfish agents on a set of parallel identical machines. A coordination mechanism consists in giving a scheduling policy to each machine. Given these policies, each agent chooses the machines on which she assigns her tasks, and her aim is to minimize the average completion times of her tasks. The aim of the system (social cost) is to minimize th...

Previous findings have demonstrated that hemispheric organization in deaf users of American Sign Language (ASL) parallels that of the hearing population, with the left hemisphere showing dominance for grammatical linguistic functions and the right hemisphere showing specialization for non-linguistic spatial functions. The present study addresses two further questions: first, do extra-grammatica...

This paper presents the results of a sentence completion study and a self-paced reading experiment involving a relative clause attachment ambiguity. Our results provide evidence that comprehenders resolve local structural ambiguity during incremental sentence processing by combining expectations about upcoming discourse continuations with their knowledge of typical relationships between event p...
