On Heads and Coordination in Valence Acquisition

Abstract. The aim of this paper is to present the design of a partial syntactic annotation of the IPI PAN Corpus of Polish [22] and the cor-responding extension of the corpus search engine Poliqarp [25,12] devel-oped at the Institue of Computer Science PAS and currently employed in Polish and Portuguese corpora projects. In particular, we will argue for the need to distinguish between, and represent both, syntactic and se-mantic heads, and we will sketch the representation of coordination, the area traditionally controversial both in theoretical and in computational linguistics. The annotation is designed in a way intended to maximise the usefulness of the resulting corpus for the task of automatic valence acquisition

Ad-nominal epistemic adverbials at the syntax–semantics interface

This paper provides an analysis of adnominal uses of epistemic adverbials at the syntax–semantics interface. The analysis is couched in Lexical Functional Grammar (LFG) and Glue Semantics (GS)

An English dependency treebank à la Tesnière

During the last decade, the Computational Linguistics community has shown an increased interest in Dependency Treebanks. Several groups have developed new annotated corpora using dependency representation, while other people have proposed several automatic conversion algorithms to transform available Phrase Structure (PS) treebanks into Dependency Structure (DS) notation. Such projects typically refer to Tesnière as the father of dependency syntax, but little attempt has been made to explain how the chosen representation relates to the original work. A careful comparison reveals substantial differences: modern DS annotations discard some relevant features characterizing Tesnière’s model. This paper is presenting our attempt to go back to the roots of dependency theory, and show how it is possible to transform a PS English treebank to a DS notation that is closer to the one proposed by Tesnière, which we will refer to as TDS. We will show how this representation can incorporate all main advantages of modern DS, while avoiding well known problems concerning the choice of heads, and better representing common linguistic phenomena such as coordination

An HPSG-Annotated Test Suite for Polish

The paper presents both conceptual and technical issues related to the construction of an HPSG test-suite for Polish. The test-suite consists of sentences of written Polish --- both grammatical and ungrammatical. Each sentence is annotated with a list of linguistic phenomena it illustrates. Additionally, grammatical sentences are encoded in HPSG-style AVM structures. We describe also a technical organization of the database, as well as possible operations on it. 1. Aims and Design Constraints The aim of this paper 1 is to describe Baza Rozbiorow Gramatycznych (Database of Grammatical Parses) --- a test-suite of written Polish sentences, created as a part of the European Union CRIT-2 project. The idea is based on the TSNLP project (Lehmann et al., 1996; Oepen et al., 1998), which resulted in creating test-suites for various European languages. As a test-suite, BRG contains not only grammatical sentences but also ungrammatical ones, violating various linguistic rules. At the moment, ..
