Data Set Used
When a dataset involves multiple classes, there is often a need to express the key contrasting features among these classes in humanly understandable terms, that is, to proole the classes. Commonly, one class is contrasted from the rest by aggregating the latter into a pseudo-class; alternatively, classes are treated separately without coordinating their… (More)
The paper describes a novel computational tool for multiple concept learning. Unlike previous approaches, whose major goal is prediction on unseen instances rather than the legibility of the output, our MPD (Maximally Parsimonious Discrimination) program emphasizes the conciseness and intelligibility of the resultant class descriptions, using three… (More)
We describe a discovery program, called UNIVAUTO (UNIVersals AUthoringTOol), whose domain of application is the study of language universals, a classic trend in contemporary linguistics. Accepting as input information about languages, presented in terms of feature-values, the discoveries of another human agent arising from the same data, as well as some… (More)
The empirical validity of the projeetivity hypothesis for Bulgarian is tested. It is shown that the justification of the hypothesis presented for other languages suffers serious methodological deficiencies. Our automated testing, designed to evade such defi-ciencies~ yielded results falsifying the hypothesis for Bulgarian: the non-projective constructions… (More)
The difficulties to be met with the resolution of syntactical ambiguity in MT can be at least partially overcome by means of preserving the syntactical ambiguity of the source language into the target language. An extensive study of the correspondences between the syntactically ambiguous structures in English and Bulgarian has provided a solid empirical… (More)
A logic formalism is presented which increases the expressive power of the ID/LP format of GPSG by enlarging the inventory of ordering relations and extending the domain of their application to non-siblings. This allows a concise, modular and declarative statement of intricate word order regularities.
In a companion paper (), I describe UNIVAUTO (UNI-Versals AUthoring TOol), a linguistic discovery program that uncovers language universals and can write a report in English on its discoveries. In this contribution, the system is evaluated along a number of parameters that have been suggested in the literature as necessary ingredients of a successful… (More)
