Patent translation is a complex problem due to the highly specialized technical vocab- ulary and the peculiar textual structure of patent documents. In this paper we analyze patents along the orthogonal dimensions of topic and textual structure. We view differ- ent patent classes and different patent text sections such as …...

A composition procedure for linear and nondeleting extended top-down tree trans- ducers is presented. It is demonstrated that the new procedure is more widely applica- ble than the existing methods. In general, the result of the composition is an extended top-down tree transducer that is no longer linear or nondeleting, …...

While information status (IS) plays a cru- cial role in discourse processing, there have only been a handful of attempts to automat- ically determine the IS of discourse entities. We examine a related but more challenging task, fine-grained IS determination, which involves classifying a discourse entity as one of 16 …...

Speech style accommodation refers to shifts in style that are used to achieve strate- gic goals within interactions. Models of stylistic shift that focus on specific fea- tures are limited in terms of the contexts to which they can be applied if the goal of the analysis is to model …...

We compare the impact of sentence- internal vs. sentence-external features on word order prediction in two generation settings: starting out from a discrimina- tive surface realisation ranking model for an LFG grammar of German, we enrich the feature set with lexical chain features from the discourse context which can be …...

We present a system for the real-time gen- eration of car navigation instructions with landmarks. Our system relies exclusively on freely available map data from Open- StreetMap, organizes its output to fit into the available time until the next driving ma- neuver, and reacts in real time to driving er- …...

This paper introduces a novel generation system that composes humanlike descrip- tions of images from computer vision de- tections. By leveraging syntactically in- formed word co-occurrence statistics, the generator filters and constrains the noisy detections output from a vision system to generate syntactic trees that detail what the computer vision …...

A fundamental problem in text generation is word ordering. Word ordering is a com- putationally difficult problem, which can be constrained to some extent for particu- lar applications, for example by using syn- chronous grammars for statistical machine translation. There have been some recent attempts at the unconstrained problem of …...

When translating English to German, exist- ing reordering models often cannot model the long-range reorderings needed to gen- erate German translations with verbs in the correct position. We reorder English as a preprocessing step for English-to-German SMT. We use a sequence of hand-crafted reordering rules applied to English parse trees. …...

In pro-drop languages, the detection of explicit subjects, zero subjects and non- referential impersonal constructions is cru- cial for anaphora and co-reference resolu- tion. While the identification of explicit and zero subjects has attracted the atten- tion of researchers in the past, the auto- matic identification of impersonal construc- tions …...

In this paper, we propose an annota- tion schema for the discourse analysis of Wikipedia Talk pages aimed at the coor- dination efforts for article improvement. We apply the annotation schema to a cor- pus of 100 Talk pages from the Simple English Wikipedia and make the resulting dataset freely …...

We propose an unsupervised, iterative method for detecting downward-entailing operators (DEOs), which are important for deducing entailment relations between sen- tences. Like the distillation algorithm of Danescu-Niculescu-Mizil et al. (2009), the initialization of our method depends on the correlation between DEOs and negative po- larity items (NPIs). However, our method …...

The task of paraphrase acquisition from re- lated sentences can be tackled by a variety of techniques making use of various types of knowledge. In this work, we make the hypothesis that their performance can be increased if candidate paraphrases can be validated using information that character- izes paraphrases independently …...

Widely accepted resources for semantic parsing, such as PropBank and FrameNet, are not perfect as a semantic role label- ing framework. Their semantic roles are not strictly defined; therefore, their mean- ings and semantic characteristics are un- clear. In addition, it is presupposed that a single semantic role is assigned …...

The current state-of-the-art in statistical machine translation (SMT) suffers from is- sues of sparsity and inadequate modeling power when translating into morphologi- cally rich languages. We model both in- flection and word-formation for the task of translating into German. We translate from English words to an underspecified German representation and …...

We propose a novel method for learning morphological paradigms that are struc- tured within a hierarchy. The hierarchi- cal structuring of paradigms groups mor- phologically similar words close to each other in a tree structure. This allows detect- ing morphological similarities easily lead- ing to improved morphological segmen- tation. Our …...

Morphological lexica are often imple- mented on top of morphological paradigms, corresponding to different ways of building the full inflection table of a word. Compu- tationally precise lexica may use hundreds of paradigms, and it can be hard for a lex- icographer to choose among them. To au- tomate this …...

Better representations of plot structure could greatly improve computational meth- ods for summarizing and generating sto- ries. Current representations lack abstrac- tion, focusing too closely on events. We present a kernel for comparing novelistic plots at a higher level, in terms of the cast of characters they depict and the …...

Open issue trackers are a type of social me- dia that has received relatively little atten- tion from the text-mining community. We investigate the problems inherent in learn- ing to triage bug reports from time-varying data. We demonstrate that concept drift is an important consideration. We show the effectiveness of …...

Informal and formal (“T/V”) address in dia- logue is not distinguished overtly in mod- ern English, e.g. by pronoun choice like in many other languages such as French (“tu”/“vous”). Our study investigates the status of the T/V distinction in English liter- ary texts. Our main findings are: (a) human raters …...
