An HSPG-to-CFG Approximation of Japanese
(2000)
-
Bernd Kiefer

- We present a simple approximation method for turning a Head-Driven Phrase Structure Grammar into a context-free grammar. The approximation method can be seen as the construction of the least fixpoint of a certain monotonic function. We discuss an experiment with a large HPSG for Japanese.

Annotating Honorifics Denoting Social Ranking of Referents
(2005)
-

Melanie Siegel
- This paper proposes an annotating scheme that encodes honorifics (respectful words). Honorifics are used extensively in Japanese, reflecting the social relationship (e.g. social ranks and age) of the referents. This referential information is vital for resolving zero
pronouns and improving machine translation outputs. Annotating honorifics is a complex task that involves identifying a predicate with honorifics, assigning ranks to referents of the
predicate, calibrating the ranks, and connecting referents with their predicates.

Definitheit und Numerus : Anforderungen an den Transfer Japanisch-Englisch
(1994)
-
Melanie Siegel
- Das Problem des Transfers in der maschinellen Übersetzung von Japanisch nach Englisch ist fehlende Information über Numerus und Definitheit im Japanischen, die für die Wahl der englischen Artikel und die Nomenmarkierung gebraucht wird. Obwohl dieses Problem signifikant ist, beschäftigt sich die Forschungsliteratur kaum damit. [...] Wir bsaieren unsere Untersuchungen auf experimentell erhobenen Daten aus einem Experiment über deutsch-japanische gedolmetschte Terminaushandlungsdialoge [...]. Auf diese Weise können Phänomene bestimmt werden, die für die Domäne von VERBMOBIL relevant sind. Wir sehen unser Vorgehen in Übereinstimmung mit dem 'Sublanguage'-Ansatz [...].

Die japanische Syntax im Verbmobil Forschungsprototypen
(1996)
-
Melanie Siegel
- Die Domäne in VERBMOBIL sind Terminaushandlungsdialoge. Für die Syntax bedeutet das zunächst, daß die Sytnax sich an gesprochener Sprache orientieren muß. Das beinhaltet Nullanaphern, Phrasen, die auf die Kommunikationssituation bezogen sind und Phrasen, die für geschriebene Sprache als nicht wohlgeformt bezeichnet werden. Weitergehend gibt es einige domänenspezifische syntaktische besonderheiten, wie zum Biepsiel die Realisierung von Zeitangaben.

Efficient Deep Processing of Japanese
(2002)
-
Melanie Siegel
Emily M. Bender
- We present a broad coverage Japanese grammar written in the HPSG formalism with MRS semantics. The grammar is created for use in real world applications, such that robustness and performance issues play an important role. It is connected to a POS tagging and word segmentation tool. This grammar is being developed in a multilingual context, requiring MRS structures that are easily comparable across languages.

Head-Initial Constructions in Japanese
(2004)
-
Melanie Siegel
Emily M. Bender
- Japanese is often taken to be strictly head-final in its syntax. In our work on a broad-coverage, precision implemented HPSG for Japanese, we have found that while this is generally true, there are nonetheless a few minor exceptions to the broad trend. In this paper, we describe the grammar engineering project, present the exceptions we have found, and conclude that this kind of phenomenon motivates on the one hand the HPSG type hierarchical approach which allows for the statement of both broad generalizations and exceptions to those generalizations and on the other hand the usefulness of grammar engineering as a means of testing linguistic hypotheses.

Implementing the Syntax of Japanese Numeral Classifiers
(2004)
-
Emily M. Bender
Melanie Siegel
- While the sortal constraints associated with Japanese numeral classifiers are wellstudied, less attention has been paid to the details of their syntax. We describe an analysis implemented within a broadcoverage HPSG that handles an intricate set of numeral classifier construction types and compositionally relates each to an appropriate semantic representation, using Minimal Recursion Semantics.

JACY - A Grammar for Annotating Syntax, Semantics and Pragmatics of Written and Spoken Japanese for NLP Application Purposes
(2006)
-
Melanie Siegel
- In this text, we describe the development of a broad coverage grammar for Japanese that has
been built for and used in different application contexts. The grammar is based on work done
in the Verbmobil project (Siegel 2000) on machine translation of spoken dialogues in the
domain of travel planning. The second application for JACY was the automatic email
response task. Grammar development was described in Oepen et al. (2002a). Third, it was
applied to the task of understanding material on mobile phones available on the internet, while
embedded in the project DeepThought (Callmeier et al. 2004, Uszkoreit et al. 2004).
Currently, it is being used for treebanking and ontology extraction from dictionary definition
sentences by the Japanese company NTT (Bond et al. 2004).
