In this paper, we present the JUCSE system, designed for the TempEval-3 shared task. The system extracts events and temporal information from natural text in English. We have participated in all the tasks of TempEval-3, namely Task A, Task B & Task C. We have primarily utilized the Conditional Random Field (CRF) based machine learning technique, for all the above tasks. Our system seems to perf...

There is an extensive literature on task modelling related to the design of computer systems. Task analysis and task modelling have been widely recognized as central components in human-centred approaches. The aim of this paper is to report on some results of a worldwide survey about actual practices of task descriptions languages (TDL) in SIGCHI community. Results suggest that academic TDL are...

q-mode hierarchical cluster (hca) and principal component analysis (pca) were simultaneously applied to groundwater hydrochemical data from the three times in 2004: june, september, and december, along the ain azel aquifer, algeria, to extract principal factors corresponding to the different sources of variation in the hydrochemistry, with the objective of defining the main controls on the h...

schema matching is a critical step in many applications, such as data warehouse loading, online analytical process (olap), data mining, semantic web [2] and schema integration. this task is defined for finding the semantic correspondences between elements of two schemas. recently, schema matching has found considerable interest in both research and practice. in this paper, we present a new impr...

Conditional real-time task models, which are generalizations of periodic, sporadic, and multi-frame tasks, represent real world applications more accurately. These models can be classified based on a tradeoff in two dimensions – expressivity and hardness of schedulability analysis. In this work, we introduce a class of conditional task models and derive efficient schedulability analysis techniq...

patients and methods subjects of this study include teaching hospitals in mashhad, affiliated with mashhad university of medical sciences and the tool used in gathering the data was a questionnaire, completed based on the information provided by the proceedings of the meetings held by the ethics committees. also, for the purpose of gathering the suggestions, specifically on the improvement of t...

Recently, the role of task analysis in design has been brought into question. It has been argued, for example, that task analysis leads to the non-creative redesign of existing artefacts. In this paper. we offer a view of task analysis that resolves this problem. In particular, we argue that by focusing upon the analysis of user/operator goals rather than an existing task implementation, task a...

The IBM Task Modeler supports the rapid creation and analysis of hierarchical task models, thereby providing a valuable and naturally visual tool for information architects. Task Modeler not only facilitates the essential processes of design, validation, and modification but also enables an information architect to develop and apply schemes for information classification.
