Issues in the addition of ISO Standard annotations to the Switchboard corpus
Proceedings of the 9th Joint ISO ACL SIGSEM Workshop on Interoperable Semantic Annotation (ISA-9), 2013Co-Authors: Harry Bunt, Alex C Fang, Xiaoyue LiuAbstract:This paper analyzes the issues that arise when trying to add annotations to the dia-logues in the Switchboard corpus according to ISO Standard 24617-2, exploiting the ex-isting SWBD-DAMSL annotations. These issues relate to differences between the two tag sets; to the highly multidimensional view that underlies the ISO Standard; to differ-ences in segmenting the dialogues into func-tional units; to the use of in-line markups for certain phenomena in Switchboard, and to the use of intra-dialogue dependence rela-tions as defined in the ISO Standard. The analysis is supplemented by a discus-sion of how the existing annotations may be helpful to semi-automatically create a fully-fledged ISO Standard annotation alongside the existing SWBD-DAMSL annotation.

ISO 24617-2 : A semantically-based Standard for dialogue annotation
Proceedings of LREC 2012, 2012Co-Authors: Harry Bunt, Jae-woong Choe, Alex Chengyu Fang, Volha Petukhova, Kôiti Hasida, Andrei Popescu-belis, Jan Alexandersson, David TraumAbstract:This paper summarizes the latest, final version of ISO Standard 24617-2 “Semantic annotation framework, Part 2: Dialogue actsâ€. Compared to the preliminary version ISO DIS 24617-2:2010, described in Bunt et al. (2010), the final version additionally includes concepts for annotating rhetorical relations between dialogue units, defines a full-blown compositional semantics for the Dialogue Act Markup Language DiAML (resulting, as a side-effect, in a different treatment of functional dependence relations among dialogue acts and feedback dependence relations); and specifies an optimally transparent XML-based reference format for the representation of DiAML annotations, based on the systematic application of the notion of ‘ideal concrete syntax’. We describe these differences and briefly discuss the design and implementation of an incremental method for dialogue act recognition, which proves the usability of the ISO Standard for automatic dialogue annotation.

Using DiAML and ANVIL for multimodal dialogue annotation
Proc. of LREC 2012, 2012Co-Authors: Harry Bunt, Michael Kipp, Volha PetukhovaAbstract:This paper shows how interoperable annotations of multimodal dialogue, which apply the annotation scheme and the markup language (DiAML, Dialogue Act Markup Language) defined ISO Standard 24617-2, can conveniently be obtained using the newly implemented facility in the ANVIL annotation tool to produce XML-based output directly in the DiAML format. ANVIL offers the use of multiple user-defined ‘tiers’ for annotating various kinds of information. This is shown to be convenient not only for multimodal information but also for dialogue act annotation according to ISO Standard 24617-2 because of the latter’s multidimensionality: functional dialogue segments are viewed as expressing one or more dialogue acts, and every dialogue act belongs to one of a number of dimensions of communication, defined in the Standard, for each of which a different ANVIL tier can conveniently be used. Annotations made in the multi-tier interface can be exported in the ISO 24617-2 format, thus supporting the creation of interoperable annotated corpora of multimodal dialogue.

Collaborative Annotation of Dialogue Acts: Application of a New ISO Standard to the Switchboard Corpus
Eacl 2012, 2012Co-Authors: Ac Fang, Harry Bunt, Jing CaoAbstract:This article reports some initial results from the collaborative work on converting SWBD-DAMSL annotation scheme used in the Switchboard Dialogue Act Corpus to ISO DA annotation framework, as part of our on-going research on the interoperability of Standardized linguistic annotations. A qualitative assessment of the conversion between the two annotation schemes was performed to verify the applicability of the new ISO Standard using authentic transcribed speech. The results show that in addition to a major part of the SWBD-DAMSL tag set that can be converted to the ISO DA scheme automatically, some problematic SWBD-DAMSL tags still need to be handled manually. We shall report the evaluation of such an application based on the preliminary results from automatic mapping via machine learning techniques. The paper will also describe a user-friendly graphical interface that was designed for manual manipulation. The paper concludes with discussions and suggestions for future work.

towards an ISO Standard for dialogue act annotation
Language Resources and Evaluation, 2010Co-Authors: Harry Bunt, Jae-woong Choe, Alex Chengyu Fang, Volha Petukhova, Kôiti Hasida, Jan Alexandersson, Laurent Romary, Jean Carletta, Andrei Popescubelis, Claudia SoriaAbstract:This paper describes an ISO project which aims at developing a Standard for annotating spoken and multimodal dialogue with semantic information concerning the communicative functions of utterances, the kind of semantic content they address, and their relations with what was said and done earlier in the dialogue. The project, ISO 24617-2 "Semantic annotation framework, Part 2: Dialogue acts", is currently at DIS stage. The proposed annotation schema distinguishes 9 orthogonal dimensions, allowing each functional segment in dialogue to have a function in each of these dimensions, thus accounting for the multifunctionality that utterances in dialogue often have. A number of core communicative functions is defined in the form of ISO data categories, available at http://semantic-annotation.uvt.nl/dialogue-acts/ISO-datcats.pdf; they are divided into "dimension-specific" functions, which can be used only in a particular dimension, such as Turn Accept in the Turn Management dimension, and "general-purpose" functions, which can be used in any dimension, such as Inform and Request. An XML-based annotation language, "DiAML" is defined, with an abstract syntax, a semantics, and a concrete syntax.

a proposal for an ISO Standard for public key encryption version 2 0
2001Co-Authors: Victor ShoupAbstract:This document should be viewed less as a first draft of a Standard for public-key encryption, and more as a proposal for what such a draft Standard should contain. It is hoped that this proposal will serve as a basis for discussion, from which a consensus for a Standard may be formed. Summary of Changes from version 1.1 (February 13, 2001) to version 2.0 (September 17, 2001) • Some new and quite severe criticisms of the security of ECIES in certain modes of operation have been added. Specifically, it is shown that in certain modes of operation, the scheme is malleable in a very strong and quite non-trivial sense. See §15 and in particular §15.6.4. • The implementation of “cofactor mode” for ECIES is now based on the notion of “compatible cofactor mode” in IEEE P1363a, and the “old cofactor mode” is no longer recommended. See §15 as well as §15.6.5. • A new “primitive” called a data encapsulation mechanism has been introduced (see §4). This primitive was implicit in previous versions, but now it has been made explicit. This is mainly just a conceptual change. Note, however, that there is one slight change in the recommended implementation of the primitive (which we call DEM1); namely, the way in which the length of the label is formatted when passed to the MAC. This is done so as to align with IEEE P1363a. This change affects ECIES, as well as other hybrid schemes. See §10. • A new section has been added that details all the differences between our recommended version of ECIES and that recommended in the IEEE P1363a Standard. Note that our recommended version of ECIES is consistent with the IEEE P1363a version — the only differences between the two are that our recommended version does not allow several options and modes of operations allowed by the IEEE P1363a version. See §15.6. • Two changes were made to ACE-KEM (formerly ACE-Encrypt ′). First, the value of v is now encoded in the ciphertext using the group encoding function, rather than the partial encoding function as in previous versions. This was done mainly for aesthetic reasons. Second, the implementation of “cofactor mode” has been changed to align with the IEEE P1363a notion of “compatible cofactor mode.” See §17. • It is now recommended that all Diffie-Hellman-based schemes use prime order subgroups. This is done mainly for alignment with other Standards, as well overall consistency. • Following discussions in Santa Barbara, this report now recommends inclusion of EPOC-2 in the Standard, although this report does not yet include a detailed specification of EPOC-2. • A new final section has been added that recommends the next steps to be taken toward an ISO Standard. See §21. • A number of names have been changed. Some of these name changes were suggested by working group members, while others were made to increase overall consistency. old name new name ECIES ′ ECIES-KEM PSEC-2 ′ PSEC-KEM ACE-Encrypt ′ ACE-KEM Simple RSA RSA-KEM EME-OAEP OAEP-EME XEME-OAEP+ OAEP+XEME • A number of other, essentially aesthetic, changes.

system accuracy evaluation of 43 blood glucose monitoring systems for self monitoring of blood glucose according to din en ISO 15197
Journal of diabetes science and technology, 2012Co-Authors: Guido Freckmann, Christina Schmid, Annette Baumstark, Stefan Pleus, Manuela Link, Cornelia HaugAbstract:Background: The accuracy of systems for self-monitoring of blood glucose is important, as reliable measurement results are a prerequisite for therapeutic decisions. Methods: This system accuracy evaluation study was performed according to DIN EN ISO 15197:2003 for 43 Conformite Europeenne (CE)-labeled blood glucose (BG) monitoring systems. Measurement results of each system were compared with results of the designated comparISOn method (manufacturer’s measurement procedure): glucose oxidase method (YSI 2300 glucose analyzer) or hexokinase method (Hitachi 917/ cobas 501). Results: Complete assessment according to the International Organization for Standardization (ISO) Standard was performed for 34 out of 43 systems, and 27 (79.4%) meet the requirements of the Standard, i.e., ≥95% of their results showed at least the minimum acceptable accuracy. For 9 of the 43 systems, complete accuracy assessment was not performed due to an oxygen sensitivity (manufacturer’s labeling). The bias (according to Bland and Altman) of all 43 evaluated systems ranged from -14.1% to +12.4%. Conclusions: From the 34 systems completely assessed, 7 systems did not fulfill the minimal accuracy requirements of the ISO Standard. The CE mark apparently does not guarantee that all BG systems provide accuracy according to the Standard. Because inaccurate systems bear the risk of false therapeutic decisions, regular and Standardized evaluation of BG meters and test strips should be requested in order to ensure adherence to quality Standards.
