In this paper we discuss the problenl of ascribing beliefs to an agent, given partial knowledge of his beliefs. The particular kind of ascription we are interested in we call explanatory ascription, since it ascribes beliefs to an agent as a means of explaining the beliefs we already know he has. We explore two approaches to explanatory ascription. In the first, we develop a model of belief cal...

In a morphological lexicon, each entry combines a lemma with a specific inflection class, often defined by a set of inflection rules. Therefore, such lexica usually give a satisfying account of inflectional operations. Derivational information, however, is usually badly covered. In this paper we introduce a novel approach for enriching morphological lexica with derivational links between entrie...

The paper presents construction of Derywator – a language tool for the recognition of Polish derivational relations. It was built on the basis of machine learning in a way following the bootstrapping approach: a limited set of derivational pairs described manually by linguists in plWordNet is used to train Derivator. The tool is intended to be applied in semi-automated expansion of plWordNet wi...

We show that in the context of orthogonal term rewriting systems, derivational complexity is an invariant cost model, both in innermost and in outermost reduction. This has some interesting consequences for (asymptotic) complexity analysis, since many existing methodologies only guarantee bounded derivational complexity.

The present paper deals with the double verb patterns go-and-V and go-V. While generative approaches have argued that the latter are truncated surface forms derived from the former, the present paper adds to the empirical evidence obtained so far, arguing in favor of the view that the two patterns be adequately conceived of as separate constructions (the notion of construction being defined in ...

The primary aim of this paper is to argue that a unified approach to strong and weak islands is misguided: strong and weak islands are different phenomena, to be accounted for at different levels of representation. Our central claim is that a theory of locality that represents these islands in one level cannot capture the pattern of island sensitivity exhibited by the various grammatical depend...

Recent work in syntactic theory has been much concerned with the issue of derivationality vs. representationality in the application of syntactic principles. Arguments for an essentially derivational approach to syntactic relations, whereby syntactic principles apply in an on-line fashion, during the course of the derivation, rather than at independently identified levels of representation such...
