Verso la costruzione di una biblioteca digitale.

A data base of the "Antonio Zampolli Fund" has been created and the respective catalogue has been published1. The work of analysis and selection of texts for cataloguing helped in creating this bibliography, in large part built on references extracted by books and journals. Very old bibliographical references have also been retrieved by curricula prepared by Professor Zampolli for various projects and commissions

\u2018Ontology\u2019 and Terminological Frameworks: an Overview of Issues and Term(s)

This paper addresses the question of the protean nature of \u2018ontology\u2019, with special attention paid to its use within the domain of terminology theories and applications. This term is widely used nowadays within various disciplines for designating different types of organising relational frameworks. Yet, its designations remain unvaried and, in this way, it causes ambiguity. The multifaceted nature of the so-called \u2018ontology\u2019 hinders the possibility of providing an unambiguous defi nition. This is mainly due to the multi- and interdisciplinary dimension of this notion, which is outlined here through an overview of its application within philosophy, information science, and linguistic disciplines. The reference model of ontology that is applied nowadays in various disciplines corresponds to an object, or more precisely, to various types of objects which are all based on a relational framework, and are used for organising different types of knowledge units. This view differs from the original value of ontology that was shaped within philosophy as a purely theoretical model, a global and universally-valid abstract classifi cation of reality. Therefore, it seems appropriate that this term should acquire greater precision especially when it is used within the domain of terminology

XMG : eXtensible MetaGrammar

International audienceIn this article, we introduce eXtensible MetaGrammar (xmg), a framework for specifying tree-based grammars such as Feature-Based Lexicalised Tree-Adjoining Grammars (FB-LTAG) and Interaction Grammars (IG). We argue that xmg displays three features which facilitate both grammar writing and a fast prototyping of tree-based grammars. Firstly, \xmg\ is fully declarative. For instance, it permits a declarative treatment of diathesis that markedly departs from the procedural lexical rules often used to specify tree-based grammars. Secondly, the \xmg\ language has a high notational expressivity in that it supports multiple linguistic dimensions, inheritance and a sophisticated treatment of identifiers. Thirdly, xmg is extensible in that its computational architecture facilitates the extension to other linguistic formalisms. We explain how this architecture naturally supports the design of three linguistic formalisms namely, FB-LTAG, IG, and Multi-Component Tree-Adjoining Grammar (MC-TAG). We further show how it permits a straightforward integration of additional mechanisms such as linguistic and formal principles. To further illustrate the declarativity, notational expressivity and extensibility of \xmg , we describe the methodology used to specify an FB-LTAG for French augmented with a unification-based compositional semantics. This illustrates both how xmg facilitates the modelling of the tree fragment hierarchies required to specify tree-based grammars and of a syntax/semantics interface between semantic representations and syntactic trees. Finally, we briefly report on several grammars for French, English and German that were implemented using \xmg\ and compare \xmg\ to other existing grammar specification frameworks for tree-based grammars

Research in the Language, Information and Computation Laboratory of the University of Pennsylvania

This report takes its name from the Computational Linguistics Feedback Forum (CLiFF), an informal discussion group for students and faculty. However the scope of the research covered in this report is broader than the title might suggest; this is the yearly report of the LINC Lab, the Language, Information and Computation Laboratory of the University of Pennsylvania. It may at first be hard to see the threads that bind together the work presented here, work by faculty, graduate students and postdocs in the Computer Science and Linguistics Departments, and the Institute for Research in Cognitive Science. It includes prototypical Natural Language fields such as: Combinatorial Categorial Grammars, Tree Adjoining Grammars, syntactic parsing and the syntax-semantics interface; but it extends to statistical methods, plan inference, instruction understanding, intonation, causal reasoning, free word order languages, geometric reasoning, medical informatics, connectionism, and language acquisition. Naturally, this introduction cannot spell out all the connections between these abstracts; we invite you to explore them on your own. In fact, with this issue it’s easier than ever to do so: this document is accessible on the “information superhighway”. Just call up http://www.cis.upenn.edu/~cliff-group/94/cliffnotes.html In addition, you can find many of the papers referenced in the CLiFF Notes on the net. Most can be obtained by following links from the authors’ abstracts in the web version of this report. The abstracts describe the researchers’ many areas of investigation, explain their shared concerns, and present some interesting work in Cognitive Science. We hope its new online format makes the CLiFF Notes a more useful and interesting guide to Computational Linguistics activity at Penn
