Extracting biomedical relations such as drug-drug interaction (DDI) from text is an important task in biomedical NLP. Due to the large number of complex sentences in biomedical literature, researchers have employed some sentence simplification techniques to improve the performance of the relation extraction methods. However, due to difficulty of the task, there is no noteworthy improvement in t...

Although gait-related dual-task interference in aging is well established, the effect of gait and cognitive task difficulty on dual-task interference is poorly understood. The purpose of this study was to examine the effect of gait and cognitive task difficulty on cognitive-motor interference in aging. Fifteen older adults (72.1 years, SD 5.2) and 20 young adults (21.7 years, SD 1.6) performed ...

This paper examines the theoretical rationales and practical aspects of task-based language teaching (TBLT) with particular reference to research findings in EFL/ESL contexts. The definitional scope of the term ‘task’, polarizations in terms of task vs. non-task, and its relation to different language teaching approaches have engendered conceptual and methodological ambiguities.  Moreover, fact...

The effects of the sensory modality of the lead stimulus and of task difficulty on attentional modulation of the electrical and acoustic blink reflex were examined. Participants performed a discrimination and counting task with either two acoustic, two visual, or two tactile lead stimuli. In Experiment 1, facilitation of the electrically elicited blink was greater during task-relevant than duri...

This paper describes ongoing research on the development of a hybrid planning system that integrates casebased reasoning (CBR) methods into SIPE-2,t a generative planning system. Novel aspects of this work include the integration of CBR methods with a hierarchical task network (HTN) planner; the estimation of adaptation cost based on a classification of planning conditions; the reuse of plans u...
