The effect of stance width on postural responses to 12 different directions of surface translations was examined. Postural responses were characterized by recording 11 lower limb and trunk muscles, body kinematics, and forces exerted under each foot of 7 healthy subjects while they were subjected to horizontal surface translations in 12 different, randomly presented directions. A quasi-static a...

BACKGROUND To date, no direct measurement has been done that quantitatively characterizes the foot-ground contact during Tai Chi Chuan movements. The goal of this study was to quantify the biomechanical characteristics of foot-ground contact during a Tai Chi gait (TCG), one of the basic but common Tai Chi Chuan movements. METHODS The ground reaction force profiles, center of pressure (COP) an...

This paper introduces a new class of temporal expression – named temporal expressions – and methods for recognising and interpreting its members. The commonest temporal expressions typically contain date and time words, like April or hours. Research into recognising and interpreting these typical expressions is mature in many languages. However, there is a class of expressions that are less typ...

We describe SUTIME, a temporal tagger for recognizing and normalizing temporal expressions in English text. SUTIME is available as part of the Stanford CoreNLP pipeline and can be used to annotate documents with temporal information. It is a deterministic rule-based system designed for extensibility. Testing on the TempEval-2 evaluation corpus shows that this system outperforms state-of-the-art...

This paper describes the system implemented by the NLP GROUP AT UNED for the Knowledge Base Population 2013 English Slot Filling (SF) and Temporal Slot Filling (TSF) tasks. For the Slot Filling task, we implemented a distant supervision approach, using Freebase as a source of training relations and news sources to retrieve training examples. For the Temporal Slot Filling task, our approach is b...

The temporal expressions recognition and normalization system for Spanish language described in this paper was presented by the University Carlos III de Madrid to the NIST ACE07 evaluation. The system focuses on the primary TERN task in Spanish, a pilot experience this year. The description of its architecture and modules is detailed, as well as the rule-based approach implemented by a finite s...

Temporal expressions are words or phrases that describe a point, duration or recurrence in time. Automatically annotating these expressions is a research goal of increasing interest. Recognising them can be achieved with supervised machine learning, but interpreting them accurately (normalisation) is a complex task requiring human knowledge. In this paper, we present TIMEN, a community-driven t...

We see a temporal data warehouse as a set of temporal views defined in the past fragment of the temporal relational algebra extended with set-valued attributes and aggregation. This paper proposes an incremental maintenance method for temporal views that allows improvements over the re-computation from scratch. We introduce a formalism for temporal data warehouse specification that summarizes i...

Lois Childs discussed GE's efforts to extract temporal expressions from text through the identification of relevant patterns . The Shogun system used 37 patterns in English, and 7 for Japanese . Patterns wer e context dependent, and referenced a dateline in order to handle relative time . The patterns were able to perform temporal calculations, and the system computed a temporal structure from ...

A serious game for learning the social skills required for effective police interviewing is a challenging idea. Building artificial conversational characters that play the role of a suspect in a police interrogation game requires computational models of police interviews as well as of the internal psychological mechanisms that determine the behaviour of suspects in this special type of dialogue...
