Joint Syntacto-Discourse Parsing and the Syntacto-Discourse Treebank

Discourse parsing has long been treated as a stand-alone problem independent from constituency or dependency parsing. Most attempts at this problem are pipelined rather than end-to-end, sophisticated, and not self-contained: they assume gold-standard text segmentations (Elementary Discourse Units), and use external parsers for syntactic features. In this paper we propose the first end-to-end discourse parser that jointly parses in both syntax and discourse levels, as well as the first syntacto-discourse treebank by integrating the Penn Treebank with the RST Treebank. Built upon our recent span-based constituency parser, this joint syntacto-discourse parser requires no preprocessing whatsoever (such as segmentation or feature extraction), achieves the state-of-the-art end-to-end discourse parsing accuracy.Comment: Accepted at EMNLP 201

Morphology-Syntax interface for Turkish LFG

This paper investigates the use of sublexical units as a solution to handling the complex morphology with productive derivational processes, in the development of a lexical functional grammar for Turkish. Such sublexical units make it possible to expose the internal structure of words with multiple derivations to the grammar rules in a uniform manner. This in turn leads to more succinct and manageable rules. Further, the semantics of the derivations can also be systematically reflected in a compositional way by constructing PRED values on the fly. We illustrate how we use sublexical units for handling simple productive derivational morphology and more interesting cases such as causativization, etc., which change verb valency. Our priority is to handle several linguistic phenomena in order to observe the effects of our approach on both the c-structure and the f-structure representation, and grammar writing, leaving the coverage and evaluation issues aside for the moment

The product system

It was some years ago after practising as an industrial designer that I experienced the power of design to convey meanings through the coordinated use of attributes which materialised out of a diversity of manufacturing processes. I was fascinated by the fact that a piece of transformed material, a curve or the enhancement of a product displayed in a shop could so strongly attract the attention of a viewer. I was puzzled by the ability of certain designers to trigger evident or obscure connotations by the complexity of the shapes of their designs. Objects have the ability to define groups of people or personalities by unconscious criteria. I observed how objects can influence cultures and nationalities and we find ourselves influenced and limited by their appearance, function and value. Can we say that designed objects function only as commodities or as marks of economic wellbeing? At the beginning of this investigation my intention was to bring some answers to general questions like this. I realised that my research would involve investigating the most recondite accounts of philosophy, sociology and the theory of knowledge. I had to start from the very foundations of the complex act of understanding and, in order to organise all the different concepts, the research is constructed from three main sections

Digital document and interpretation : re-thinking "text" and scholarship in electronic settings

The contribution starts from outlining the evolution of the scholarly production flow from the print based paradigm to the digital age and in this context it explores the opposition of digital versus analog representation modes. It then develops on the triple paradigm shift caused by genuine digital publishing and its specific consequences for the social sciences and humanities (SSH) which in turn results in re-constituting basic scholarly notions such as 'text' and 'document'. The paper concludes with discussing the specific value that could be added in systematically using digital text resources as a basis for scholarly work and also states some of the necessary conditions for such a 'digital turn' to be successful in the SSH.Der Beitrag beginnt mit einem Überblick zur Evolution des wissenschaftlichen Informationskontinuums auf dem Weg vom druckbasierten Paradigma in das digitale Zeitalter und geht in diesem Zusammenhang näher auf die Unterscheidung 'digitaler' und 'analoger' Repräsentationsmodi ein. Anschließend behandeln wir den als Folge des Übergangs zu genuin digitalen Publikationsformen erwartbaren dreifachen Paradigmenwechsel und dessen spezifische Konsequenzen für die Geistes- und Sozialwissenschaften sowie als deren Folge wiederum die Re-Konstitution elementarer Kernbegriffe geisteswissenschaftlichen Arbeitens wie 'Text' und 'Dokument'. Der Beitrag schließt mit einer Betrachtung des spezifischen Mehrwerts, der sich aus dem systematischen Rekurs auf digitale Textressourcen in den Geisteswissenschaften ergeben könnte und geht dabei auch auf die erforderlichen Vorbedingungen eines solcherart erfolgreichen 'digital turn' in den Geistes- und Sozialwissenschaften ein

SEMIOTIC AND NARRATIVE ELEMENTS IN FRANZ LISZT’S VALLÉE D’OBERMANN

Liszt’s Vallée d’Obermann, like many piano works from his Années de Pèlerinage, is explicitly linked to extramusical sources. In this case the inspiration is ostensibly Étienne Pivert de Senancour’s novel Obermann, from which Liszt includes excerpts in the piece’s epigraph. However, epigraphs and perceived extramusical inspirations are not always reliable in understanding musical narrative. Given the uncertain nature of to what extent the narrative content of Obermann influenced Liszt’s composition, this document explores an underlying level of narrative using the analytical model set forth by Byron Almén in A Theory of Musical Narrative (2008). The analysis examines semiotic and narratological elements including the interactions of topics, temporality, narrative implications rooted in harmony, and the expressive function of these elements within Sonata form. Ultimately, the results of these discursive interactions are expressed through the assignation of a narrative archetype based on Northtrop Frye’s “cycle of mythoi.

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
