Mayachitra Inc. team submitted runs for the TRECVID 2010 Multimedia Event Detection Pilot (MED) task evaluation. In this paper, we describe the preliminary set of results. The focus of this experiment for the Mayachitra Inc. team was to implement an end-to-end pilot system for multimedia event detection that (i) processes video,extracts and stores state-ofart video descriptors (ii) learns compl...

In an effort to reduce the subjectivity, cost, and complexity of evaluation methods for machine translation (MT) and other language technologies, task-based assessment is examined as an alternative to metrics-based in human judgments about MT, i.e., the previously applied adequacy, fluency, and informativeness measures. For task-based evaluation strategies to be employed effectively to evaluate...

Advance preparation of action courses toward emotional stimuli is an effective means to regulate impulsive emotional behavior. Our experiment shows that performing intentional acts of approach and avoidance in an evaluation task influences the unintended activation of approach and avoidance tendencies in another task in which stimulus valence is irrelevant. For the evaluation-relevant blocks, p...

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...

In this paper we present a query-biased summarisation interface for web searching. The summarisation system has been specifically developed to act as a component in existing web search interfaces. The summaries allow the user to more effectively assess the content of web pages. We also present an experimental investigation of this approach. Our experimental results shows the system appears to b...

In this paper we describe a novel task, namely the Diachronic Text Evaluation task. A corpus of snippets which contain relevant information for the time when the text was created is extracted from a large collection of newspapers published between 1700 and 2010. The task, subdivided in three subtasks, requires the automatic system to identify the time interval when the piece of news was written...
