This paper examines a new approach to making the evaluation of personal search systems more feasible. Comparability and diverse coverage of personal search tasks are two main issues in evaluating these systems. To address these issues, the proposed approach relies on identifying the differences between search tasks. An experiment was conducted to measure user perceptions of such differences acr...

We present a model of absolute autonomy and power in agent systems. This absolute sense of autonomy captures the agent’s liberty over an agent’s preferences. Our model characterizes an affinity between autonomy and power. We argue that agents with similar individual autonomy and power experience an adjusted level of autonomy and power due to being in a group of like agents. We then illustrate o...

abstracttask-based language teaching is considered an effective way to achieve a harmony between grammar and communication. the present study investigates two different ways of teaching modal verbs: task-based versus traditional approaches. to this purpose, an oxford placement test was administered to select 40 homogeneous participants out of a larger population who took this test. the selected...

This experimental study examined the relationship between pretend play and false-belief. Eighteen-month-old children engaged in pretend play with an experimenter using various controlled behaviors and performed a false-belief task. The results showed that the children who understood pretend play performed better on the false-belief task. This suggests that pretended play and false-belief are re...

This paper describes the third participation of IR-n system at CLEF-2003. Two previous participation are focused on Spanish monolingual task. This year, we participated in three different tasks: multilingual task (four languages), bilingual task (Italian-Spanish) and monolingual task (Spanish, German, French, Italian). This paper describes the experiments carried out as training process in orde...

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...
