The Dynamics of Discourse Situations (Extended Abstract)
No full text) Massimo Poesio University of Edinburgh Centre for Cognitive Science / HCRC 2 Buccleuch Place Edinburgh EH8 9LW, UK e-mail: [email protected] Reinhard Muskens University of Tilburg Department of Linguistics 2 Warandelaan 5000 LE Tilburg, The Netherlands e-mail: [email protected] Abstract The effects of utterances such as cue phrases, keep-turn markers, and grounding signals cannot be characterized as changes to a shared record of the propositions under discussed: the simplest (and arguably most natural) way of characterizing the meaning of these utterances is in terms of a theory in which the conversational score is seen as a record of the discourse situation, or at least of the speech acts that have been performed. The problem then becomes to explain how discourse entities are accessible. We consider three hypotheses about the dynamics of a speech act-based theory of the conversational score, and argue that they could be implemented with relatively minor modifications to the tec..
A unified representation for morphological, syntactic, semantic, and referential annotations
No full textThis paper reports on the SYN-RA (SYNtax-based Reference Annotation) project, an on-going project of annotating German newspaper texts with referential relations. The project has developed an inventory of anaphoric and coreference relations for German in the context of a unified, XML-based annotation scheme for combining morphological, syntactic, semantic, and anaphoric information. The paper discusses how this unified annotation scheme relates to other formats currently discussed in the literature, in particular the annotation graph model of Bird and Liberman (2001) and the pie-in-thesky scheme for semantic annotation
Local Entity Detection and Recognition Task EVALITA 2009
No full textThis article describes a system that detects and recognizes local entities for the Italian language. The system is divided into 2 modules, the Entity Mention Detection (EMD) module which detects all the mentions related to persons, organizations, geo-political entities and locations; and the Coreference Resolution module that recognizes which mentions refer to the same entity. Understanding entity as an object or group of objects in the world; and, mention as the textual reference of an entity.We explain the architecture of both modules and report the results of the system at the EVALITA 2009 campaign
Measure instrumental in russian
No full textWe will argue that some seemingly adverbial free DPs in the instrumental in Russian which are traditionally termed measure instrumental are best understood as secondary predicates. We present the relevant syntactic assumptions and propose a semantics of this use of DPs in the instrumental. This proposal hears on the distinction between adjunct modification and secondary predication
Structure-Preserving Pipelines for Digital Libraries
No full textMost existing HLT pipelines assume the input is pure text or, at most, HTML and either ignore (logical) document structure or remove it. We argue that identifying the structure of documents is essential in digital library and other types of applications, and show that it is relatively straightforward to extend existing pipelines to achieve ones in which the structure of a document is preserved
Supervised relation extraction for ontology learning from text based on a cognitively plausible model of relations.
No full textMost work on ontology learning from text relies on unsupervised methods for relation extraction inspired by Hearst’s work, and attempts to extract relations identified in work in formal linguistics and ontology. In this paper we present work aiming at extracting from text the set of concept attributes actually associated to concepts according to psychological research, and using state-of-the art supervised relation extraction techniques
Real adjuncts in instrumental in Russian
No full textAn adjunct-DP in the free instrumental case occurs in a number of surface positions where the DP is syntactically optional. does not depend on any element in the sentence, and has a number of different interpretations. We introduce Bailyn's proposal which postulates a uniform syntactic environment for all the uses of instr. This calls for a uniform semantics of these DPs which can nevertheless accomodate the different interpretations. Starting with the hypothesis of Roman Jakobson about the semantics of the instrumental case we formulate a semantic interpretation theory based on abduction. We give a uniform semantics for three different adjunct uses of instr in this framework. In the concluding part of the paper we discuss some possible alternatives and ramifications as well as questions and objections raised with respect to the treatment proposed in this paper
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
