A Program for Recording User Activity Data for Empirical Reading and Writing ResearchCarl, Michael (Frederiksberg, 2012)[More information][Less information]
Abstract: This paper presents a novel implementation of Translog-II. Translog-II is a Windows-oriented program to record and study reading and writing processes on a computer. In our research, it is an instrument to acquire objective, digital data of human translation processes. As their predecessors, Translog 2000 and Translog 2006, also Translog-II consists of two main components: Translog-II Supervisor and Translog-II User, which are used to create a project file, to run a text production experiments (a user reads, writes or translates a text) and to replay the session. Translog produces a log files which contains all user activity data of the reading, writing, or translation session, and which can be evaluated by external tools. While there is a large body of translation process research based on Translog, this paper gives an overview of the Translog-II functions and its data visualization options.

Abstract: Parallel treebanks have received increasing attention in the past few years, primarily due to their potential use in statistical machine translation. Creating parallel treebanks manually is a time-consuming and expensive task and for this reason there is considerable interest in creating treebanks automatically. This task can be solved using standard tools such as parsers and aligners. However, because parallel treebanks are based on parallel corpora, we are in a special situation where the same meaning is represented in two different ways. This thesis is about how we can exploit this information to create better parallel treebanks than we can by using standard tools.... URI: http://hdl.handle.net/10398/8385 Files in this item: 1

Self-formed Groups versus Automatically-formed GroupsRazmerita, Liana; Brun, Armelle (Frederiksberg, 2011)[More information][Less information]
Abstract: Group work has been adopted as an important tool to support collaborative work in order to enhance learning processes. There is a wealth of literature related to group performance and the impact of group composition on group and individual performance. However, very few studies address the issue on how to automatically form groups. This article proposes a methodology that could be used by professors to form groups automatically taking into account different criteria as well as the students’ profile. This methodology is based on a pilot study that analyzes group composition of self-formed student groups. URI: http://hdl.handle.net/10398/8553 Files in this item: 1

Abstract: Modern hearing aids use a variety of advanced digital signal processing methods in order to improve speech intelligibility. These methods are based on knowledge about the acoustics outside the ear as well as psychoacoustics. We present a novel observation based on the fact that acoustic prominence is not equal to information prominence for time intervals at the syllabic and sub-syllabic levels. The idea is that speech elements with a high degree of information can be robustly identified based on basic acoustic properties. We evaluated the correlation of (information rich) content words in the DanPASS corpus with fundamental frequency (F0) and spectral tilt across four frequency bands. Our results show a correlation of certain band-level differences and the presence of content words. Similarly, but to a lesser extent, a correlation between F0 and the presence of content words was found. The principle described here has the potential to improve the “information-to-noise” ratio in hearing aids. In addition, this concept may also be applicable in automatic speech recognition systems.

An Eye-tracking and Key-logging StudyTangsgaard Hvelplund, Kristian (Frederiksberg, 2011)[More information][Less information]
Abstract: This study is an empirical investigation of translators’ allocation of cognitive resources, and its specific aim is to identify predictable behaviours and patterns of uniformity in translators’ allocation of cognitive resources in translation. The study falls within the process-oriented translation paradigm and within the more general field of cognitive psychology. Based on models of working memory, attentional control, language comprehension and language production, a theoretical framework was developed on which hypotheses were formulated and evaluated. The study’s empirical investigation fell into three major analyses, which each dealt with one aspect of translators’ allocation of cognitive resources: distribution of cognitive resources, management of cognitive resources and cognitive load. Three indicators were identified: total attention duration (TA duration measured in seconds) indicates the distribution of cognitive resources; attention unit duration (AU duration measured in milliseconds) indicates the amount of time allocated between two attention shifts; and pupil size (measured in millimetres) indicates cognitive load, i.e. workload on working memory....

Towards a Group Formation MethodologyRazmerita, Liana; Brun, Armelle (Nordwijkerhout, 2011)[More information][Less information]

There is a wealth of literature related to group performance and the impact of group composition on group and individual performance. However, very few studies address the issue on how to automatically form groups. This article proposes a methodology that could be used by professors to form groups automatically taking into account different criteria as well as the students’ profile. This methodology is based on a pilot study that analyzes group composition of self-formed student groups. The pilot study findings suggest that students tend to form homogeneous group in terms of level of the knowledge. Furthermore, students report that working on common topics of interests was a decisive factor in forming the groups. URI: http://hdl.handle.net/10398/8335 Files in this item: 1

Abstract: This paper examines some typological differences in the discourse structure of Italian and Danish. The results of the study indicate that there are significant differences in information packing in the two languages, especially in their use of deverbalisation. Italian sentences tend to include a larger number of Elementary Discourse Units (EDUs), especially propositions, than Danish. A higher percentage of these is rhetorically backgrounded by means of non-finite and nominalised predicates. Danish text structure, on the other hand, is more informationally linear and characteristic of a higher number of finite verbs and topic shifts. The study also suggests that a more fine-grained classification of non-finite and nominalised EDUs is needed for a complete in-depth analysis of discourse constraints in different language families.

Abstract: Nonsense syllable speech materials are often used when investigating speech perception in quiet and under adverse conditions. The main advantage of using nonsense syllables over words and sentences is that the acoustic as well as the linguistic context is minimal. This paper presents three anechoic recordings of 13 male and 13 female native talkers of Danish each speaking 65 nonsense syllables repeated three times with the neutral intonation contour for Danish (in total 15210 syllables). The authors compared and ranked groups of three recordings. These three recording had the same talker and had identical phonetic content. The syllables were ranked according to the general “appropriateness” and consistency, i.e., prototypical production of the consonant-vowel (CV) with respect to applicability in speech perceptual studies. The results were compared to results of an automatic method based on acoustic measures. The two novel ideas are 1) to devise an automated method for evaluating “appropriateness” of CVs and 2) to develop a Danish CV-material annotated with an objective measure of “appropriateness” for each recorded CV. The latter would potentially render more CV’s appropriate for perceptual studies. Moreover, objective evaluation would make it possible to examine any perceptual effects of variability in CV production (for example how susceptible different renderings by the same talker of CV’s are to background noise). To the knowledge of the authors, no such material has yet been published for any language. URI: http://hdl.handle.net/10398/8412 Files in this item: 1

Korzen, Iørn; Gylling, Morten (Hamburg, 2011)[More information][Less information]
Abstract: This paper argues that translators can greatly benefit from contrastive studies of discourse structure. Cross-linguistic studies of Italian and Danish point to significant typological differences in information packaging in the two languages, especially in their use of deverbalisation. Italian sentences tend to include a larger number of Elementary Discourse Units (EDUs), especially propositions, than Danish. A higher percentage of these is rhetorically backgrounded by means of non-finite and nominalised predicates. Danish text structure, on the other hand, is more informationally linear and characterised by a higher number of finite verbs and topic shifts. These typological differences are transferred into three simple translation rules concerning 1) the number of EDUs, 2) the rhetorical structure, and 3) the textualisation of rhetorical satellites.

Buch-Kromann, Matthias; Haulrich, Martin (Frederiksberg, 2010)[More information][Less information]
Abstract: We propose a novel machine learning technique that can be used to estimate probability distributions for categorical random variables that are equipped with a natural set of classification hierarchies, such as words equipped with word class hierarchies, wordnet hierarchies, and suffix and affix hierarchies. We evaluate the estimator on bigram language modelling with a hierarchy based on word suffixes, using English, Danish, and Finnish data from the Europarl corpus with training sets of up to 1–1.5 million words. The results show that the proposed estimator outperforms modified Kneser-Ney smoothing in terms of perplexity on unseen data. This suggests that important information is hidden in the classification hierarchies that we routinely use in computational linguistics, but that we are unable to utilize this information fully because our current statistical techniques are either based on simple counting models or designed for sample spaces with a distance metric, rather than sample spaces with a non-metric topology given by a classification hierarchy.

Abstract: Eye tracking has been used successfully as a technique for measuring cognitive load in reading, psycholinguistics, writing, language acquisition etc for some time now. Its application as a technique for automatically measuring the reading ease of MT output has not yet, to our knowledge, been tested. We report here on a preliminary study testing the use and validity of an eye tracking methodology as a means of semi- and/or automatically evaluating machine translation output. 50 French machine translated sentences, 25 rated as excellent and 25 rated as poor in an earlier human evaluation, were selected. 10 native speakers of French were instructed to read the MT sentences for comprehensibility. Their eye gaze data were recorded non-invasively using a Tobii 1750 eye tracker. The average gaze time and fixation count were found to be higher for the “bad” sentences, while average fixation duration and pupil dilations were not found to be substantially different between output rated as good or bad. Comparisons between BLEU scores and eye gaze data were also made and found to correlate well with gaze time and fixation count, and to a lesser extent with pupil dilation and fixation duration. We conclude that the eye tracking data, in particular gaze time and fixation count, correlate reasonably well with human evaluation of MT output but fixation duration and pupil dilation may be less reliable indicators of reading difficulty for MT output. We also conclude that eye tracking has promise as an automatic MT Evaluation technique. URI: http://hdl.handle.net/10398/8045 Files in this item: 1

Abstract: This paper investigates properties of translation processes, as observed in the translation behaviour of student and professional translators. The translation process can be divided into a gisting, drafting and post-editing phase. We find that student translators have longer gisting phases whereas professional translators have longer post-editing phases. Long-distance revisions, which would typically be expected during post-editing, occur to the same extent during drafting as during post-editing. Further, both groups of translators seem to face the same translation problems. We suggest how those findings might be taken into account in the design of computer assisted translation tools.

Buch-Kromann, Matthias (Frederiksberg, 2010)[More information][Less information]
Abstract: DTAG is a versatile annotation tool that supports manual and semi-automatic annotation of a wide range of linguistic phenomena, including the annotation of syntax, discourse, coreference, morphology, and word alignments. It includes commands for editing general labeled graphs and graph alignments, comparing annotations, managing annotation tasks, and interfacing with a revision control system. Its visualization component can display graphs and alignments for entire texts in a compact format, with a highly flexible and configurable formatting scheme. It also provides a powerful search-replace mechanism with queries based on full first-order logic, which can be used to search for linguistic constructions and automatically apply graph transformations to collections of annotated graphs.

Hardt, Daniel; Elming, Jakob (Frederiksberg, 2010)[More information][Less information]
Abstract: A method is presented for incremental retraining of an SMT system, in which a local phrase table is created and incrementally updated as a file is translated and post-edited. It is shown that translation data from within the same file has higher value than other domain-specific data. In two technical domains, within-file data increases BLEU score by several full points. Furthermore, a strong recency effect is documented; nearby data within the file has greater value than more distant data. It is also shown that the value of translation data is strongly correlated with a metric defined over new occurrences of ngrams. Finally, it is argued that the incremental re-training prototype could serve as the basis for a practical system which could be interactively updated in real time in a post-editing setting. Based on the results here, such an interactive system has the potential to dramatically improve translation quality. URI: http://hdl.handle.net/10398/8272 Files in this item: 1

Understanding Romance and Germanic Compounding in a Lexico-typological PerspectiveMüller, Henrik Høeg (Frederiksberg, 2010)[More information][Less information]
Abstract: The title of my talk is “Informational balance. Understanding Romance and Germanic Compounding in a lexico-typological perspective”. What I basically mean by informational balance is that semantic content is distributed systematically differently between nouns and verbs in the Romance and Germanic languages, and that this distribution is complementary. I shall explain that in detail in a minute, but first I shall introduce you to the problem, which I believe can be explained on the basis of this idea about “informational balance”.

Abstract: In our paper we present a project, the aim of which is to develop innovative and advanced methods for dynamic and automatic extraction of knowledge about concepts from texts and for automatic construction of ontologies. The project builds on and further develops the results of the CAOS project - Computer-Aided Ontology Structuring - which was carried out at Copenhagen Business School in the period 1998-2007. Terminological ontologies differ from other types of ontologies by comprising feature specifications and subdivision criteria. We have formalised subdivision criteria that have been used for many years in terminology work, by introducing dimensions and dimension specifications. In the CAOS prototype, facilities for semiautomatic checking of inconsistencies were developed. URI: http://hdl.handle.net/10398/8283 Files in this item: 1

Abstract: In order to develop a harmonised and efficient IT system, such as a database, it is important to be familiar with the underlying concept model (concept systems) for the relevant domain which the IT system should be designed to accommodate, as this forms the necessary firm foundation for designing the conceptual data model. Although there is no one-to-one correlation between concept and characteristic features in the concept model and classes and attributes in the conceptual data model, there are many similarities between concept modelling and conceptual data modelling, and by closely examining the relationship between the two models, we have strived to construct an algorithm for creating conceptual data models in Unified Modelling Language (UML) on the basis of concept models that adhere to the traditional principles and methods of terminology work.
