The aim of Evalita Parsing Task is at defining and extending Italian state of the art parsing by encouraging the application of existing models and approaches. As in the Evalita’07 and ’09, the Task is organized around two tracks, i.e. Dependency Parsing and Constituency Parsing. In this paper, we describe only the Constituency Parsing track by presenting the data sets for development and testi...

We describe our participation in the INEX 2009 Entity Ranking and Link-the-Wiki tracks. We provide a detailed account of the ideas underlying our approaches to these tasks.

Trans-equatorial long-distance migrations of high-latitude breeding animals have been attributed to narrow ecological niche widths. We suggest an alternative hypothesis postulating that trans-equatorial migrations result from a possible increase in the rate at which body stores to fuel migration are deposited with absolute latitude; that is, longer, migrations away from the breeding grounds sur...

We propose a dynamic semantics of questions in dialogue that tracks the public commitments of each dialogue agent, including commitments to issues raised by questions.

The common track fusion algorithms in multi-sensor systems have some defects, such as serious imbalances between accuracy and computational cost, the same treatment of all the sensor information regardless of their quality, high fusion errors at inflection points. To address these defects, a track fusion algorithm based on the reliability (TFR) is presented in multi-sensor and multi-target envi...

Let G be a group acting on a tree X such that all edge stabilizers are finite. We extend Bestvina-Handel’s theory of train tracks for automorphisms of free groups to automorphisms of G which permute vertex stabilizers. Using this extension we show that there is an upper bound depending only on G for the complexity of the graph of groups decomposition of the fixed subgroups of such automorphisms...

One of the striking differences between MOOCs and previous innovations in the education technology field is the unprecedented interest and involvement of the general public. As MOOCs address pressing problems in higher education and the broader educational practice, awareness of the general public debate around MOOCs is essential. Understanding the public discourse around MOOCs can provide insi...
