Using the Wikipedia as a corpus, the Link-the-Wiki track, launched by INEX in 2007, aims at producing a standard procedure and metrics for the evaluation of (automated) link discovery at different element levels. In this paper, we describe the preliminary procedure for the assessment, including the topic selection, submission, pooling and evaluation. Related techniques are also presented such a...

In this issue, Gafni et al.1 provide a strong and timely case for evaluating the reliability and validity of multi-station selection centres (SCs, sometimes referred to as assessment centres). In developing this important research topic, we highlight: (i) important differences between SCs and objective structured clinical examinations (OSCEs); (ii) the importance of demonstrating the construct ...

Many tasks in speech processing involve classification of long term characteristics of a speech segment such as language, speaker, dialect, or topic. A natural technique for determining these characteristics is to first convert the input speech into a sequence of tokens such as words, phones, etc. From these tokens, we can then look for distinctive phrases, keywords, that characterize the speec...

Automatic generation of hyperlinks in multimedia video data is a subject with growing interest, as demonstrated by recent work undergone in the framework of the Search and Hyperlinking task within the Mediaeval benchmark initiative. In this paper, we compare NLP-based strategies for precise target selection in video hyperlinking exploiting speech material, with the goal of providing hyperlinks ...

This study sought to test the hypothesis that topic-selection control influences fluency in writing. A total of 29 second-year university students (9 men, 20 women) in two separate classrooms engaged in a free writing activity using different topics (both teacher-selected and self-selected) in order to determine which approach was more likely to increase writing fluency. Participants’ written o...

Statistical topic modeling has become a popular tool for analyzing large, unstructured text collections. There is a significant body of work developing sophisticated topic models and their applications. To date, however, the task of evaluating topic models has not been specifically addressed. Evaluation is an important issue: the unsupervised nature of topic models makes model selection difficu...

Clinical trials are conducted extensively in clinical research. Most often, the eligibility screening consists of manually reviewing individual (patient) health records to identify potential candidates. Automated selection can improve the selection accuracy, increase the number of selected patients, and reduce the cost of the selection process. A formal representation of clinical trial eligibil...

Transport networks serve critical functions in biological and engineered systems, and yet their design requires trade-offs between competing objectives. Due to their sessile lifestyle, plants need to optimize their architecture to efficiently acquire and distribute resources while also minimizing costs in building infrastructure. To understand how plants resolve this design trade-off, we used h...
