One of the main reasons for having low quality automatic extracts is the presence of dangling anaphors. This paper analyses the referential expressions in a corpus of human written scientific summaries and tries to identify ways for improving the quality of automatic extracts. By recording the distance between the anaphoric expressions and their referents we noticed that humans do not use an ag...

One motivation for Universal Grammar (UG) comes from the existence of induction problems in language acquisition, and their solutions. Previous induction problem characterizations have typically not recognized that INDIRECT POSITIVE evidence may be both available and useful, in addition to other types of evidence. As a case study, we investigate whether a probabilistic learner utilizing indirec...

The method of encoding communication of agents in a multi-agent system (MAS) is described. The autonomous agents communicate with each other by exchanging messages formulated in a near-to-natural language. Transparent Intensional Logic (TIL) is an expressive system primarily designed for the logical analysis of natural language; thus we make use of TIL as a tool for encoding the semantic conten...

One of the central issues in the study of discourse anaphora is concerned with the problem of anaphoric distribution in discourse, namely how to account for the choice of a particular referential/anaphoric form at a particular point in discourse. Needless to say, anaphoric distribution in discourse is a very complex phenomenon, involving, among other things, structural, cognitive and pragmatic ...
