The three motivations behind the Rand index [4], a general clustering evaluation metric, can be rephrased in coreference terms: (i) every mention is unequivocably assigned to a specific entity; (ii) entities are defined just as much by those mentions which they do not contain as by those mentions which they do contain; and (iii) all mentions are of equal importance in the determination of the e...

Our submission was a reduced version of the system described in Haghighi and Klein (2010), with extensions to improve mention detection to suit the OntoNotes annotation scheme. Including exact matching mention detection in this shared task added a new and challenging dimension to the problem, particularly for our system, which previously used a very permissive detection method. We improved this...

Induction is the process by which seen data becomes the basis for prediction of unseen data. There has long been a desire to explain the procedure in a context-free way. But Hume’s circularity problem and the no-free-lunch theorems both seem to suggest the logical impossibility of any context-free mechanism. Machine Learning takes the position that no such mechanism exists. But an alternative c...

While significant effort has been put into annotating linguistic resources for several languages, there are still many left that have only small amounts of such resources. This paper investigates a method of propagating information (specifically mention detection information) into such low resource languages from richer ones. Experiments run on three language pairs (Arabic-English, Chinese-Engl...

A black bag, needed especially for home visits, has been used since the time of Hippocrates who, in his treatise "On good manners", gave the first detailed description of a medical bag with guidelines for the required equipment and structure. Ancient Egyptian and Palestinian references also date back at least two millenniums.

In many contexts, pronouns are interpreted as referring to the character mentioned first in the previous sentence, an effect called the ‘firstmention bias’. While adults can rapidly use the first-mention bias to guide pronoun interpretation, it is unclear when this bias emerges during development. Curiously, experiments with children between two and three years old show successful use of order ...
