We present a supervised learning approach to identification of anaphoric and non-anaphoric noun phrases and show how such information can be incorporated into a coreference resolution system. The resulting system outperforms the best MUC-6 and MUC-7 coreference resolution systems on the corresponding MUC coreference data sets, obtaining F-measures of 66.2 and 64.0, respectively.

The Phrase Detectives Game-With-A-Purpose for anaphoric annotation has been live since December 2008, collecting over 2.5 million judgments on the anaphoric expressions in texts in two languages (English and Italian) from around 9,000 players. In this paper we summarize our recent work on creating a corpus using these annotations.

Highly distributed, loosely organized, independent, informal work organizations sometimes manage both joint efforts and collective welfare at least as well as centralized bureaucracies do. This aligns closely with the view that markets are superior to bureaucracies as ways of organizing both joint efforts and collective welfare. There are other forms of work organization between perfect markets...

This paper discusses a French-English corpus annotated and aligned at anaphoric level. It also presents an annotation scheme based on the study of a detailed corpus featuring different types of correspondences and mismatches. The scheme which is adapted from EAGLES recommendations, supports the alignment at anaphoric level and caters for the different kinds of mismatches.

We analyze anaphoric phenomena in the context of building an input understanding component for a conversational system for tutoring mathematics. In this paper, we report the results of data analysis of two sets of corpora of dialogs on mathematical theorem proving. We exemplify anaphoric phenomena, identify factors relevant to anaphora resolution in our domain and extensions to the input interp...

We report the results of a study of the reliability of anaphoric annotation which (i) involved a substantial number of naive subjects, (ii) used Krippendorff’s α instead of K to measure agreement, as recently proposed by Passonneau, and (iii) allowed annotators to mark anaphoric expressions as ambiguous.
