| Abstract: | The NLP community has shown a renewed interest in deeper semantic analyses, among them automatic recognition of semantic relations
in text. We present the development and evaluation of a semantic analysis task: automatic recognition of relations between
pairs of nominals in a sentence. The task was part of SemEval-2007, the fourth edition of the semantic evaluation event previously
known as SensEval. Apart from the observations we have made, the long-lasting effect of this task may be a framework for comparing
approaches to the task. We introduce the problem of recognizing relations between nominals, and in particular the process
of drafting and refining the definitions of the semantic relations. We show how we created the training and test data, list
and briefly describe the 15 participating systems, discuss the results, and conclude with the lessons learned in the course
of this exercise. |
