Increasing CMDI’s Semantic Interoperability with schema.org
Nino Meisinger | Thorsten Trippel | Claus Zinn
Proceedings of the Thirteenth Language Resources and Evaluation Conference

The CLARIN Concept Registry (CCR) is the common semantic ground for most CMDI-based profiles to describe language-related resources in the CLARIN universe. While the CCR supports semantic interoperability within this universe, it does not extend beyond it. The flexibility of CMDI, however, allows users to use other term or concept registries when defining their metadata components. In this paper, we describe our use of schema.org, a light ontology used by many parties across disciplines.

Crosswalking from CMDI to Dublin Core and MARC 21
Claus Zinn | Thorsten Trippel | Steve Kaminski | Emanuel Dima
Proceedings of the Tenth International Conference on Language Resources and Evaluation (LREC'16)

The Component MetaData Infrastructure (CMDI) is a framework for the creation and usage of metadata formats to describe all kinds of resources in the CLARIN world. To better connect to the library world, and to allow librarians to enter metadata for linguistic resources into their catalogues, a crosswalk from CMDI-based formats to bibliographic standards is required. The general and rather fluid nature of CMDI, however, makes it hard to map arbitrary CMDI schemas to metadata standards such as Dublin Core (DC) or MARC 21, which have a mature, well-defined and fixed set of field descriptors. In this paper, we address the issue and propose crosswalks between CMDI-based profiles originating from the NaLiDa project and DC and MARC 21, respectively.

Towards automatic quality assessment of component metadata
Thorsten Trippel | Daan Broeder | Matej Durco | Oddrun Ohren
Proceedings of the Ninth International Conference on Language Resources and Evaluation (LREC'14)

Measuring the quality of metadata is only possible by assessing the quality of the underlying schema and the metadata instance. We propose some factors that are measurable automatically for metadata according to the CMD framework, taking into account the variability of schemas that can be defined in this framework. The factors include among others the number of elements, the (re-)use of reusable components, the number of filled in elements. The resulting score can serve as an indicator of the overall quality of the CMD instance, used for feedback to metadata providers or to provide an overview of the overall quality of metadata within a reposi-tory. The score is independent of specific schemas and generalizable. An overall assessment of harvested metadata is provided in form of statistical summaries and the distribution, based on a corpus of harvested metadata. The score is implemented in XQuery and can be used in tools, editors and repositories.

A Metadata Editor to Support the Description of Linguistic Resources
Emanuel Dima | Christina Hoppermann | Erhard Hinrichs | Thorsten Trippel | Claus Zinn
Proceedings of the Eighth International Conference on Language Resources and Evaluation (LREC'12)

Creating and maintaining metadata for various kinds of resources requires appropriate tools to assist the user. The paper presents the metadata editor ProFormA for the creation and editing of CMDI (Component Metadata Infrastructure) metadata in web forms. This editor supports a number of CMDI profiles currently being provided for different types of resources. Since the editor is based on XForms and server-side processing, users can create and modify CMDI files in their standard browser without the need for further processing. Large parts of ProFormA are implemented as web services in order to reuse them in other contexts and programs.

A Repository for the Sustainable Management of Research Data
Emanuel Dima | Verena Henrich | Erhard Hinrichs | Marie Hinrichs | Christina Hoppermann | Thorsten Trippel | Thomas Zastrow | Claus Zinn
Proceedings of the Eighth International Conference on Language Resources and Evaluation (LREC'12)

This paper presents the system architecture as well as the underlying workflow of the Extensible Repository System of Digital Objects (ERDO) which has been developed for the sustainable archiving of language resources within the Tübingen CLARIN-D project. In contrast to other approaches focusing on archiving experts, the described workflow can be used by researchers without required knowledge in the field of long-term storage for transferring data from their local file systems into a persistent repository.

Standardizing a Component Metadata Infrastructure
Daan Broeder | Dieter van Uytvanck | Maria Gavrilidou | Thorsten Trippel | Menzo Windhouwer
Proceedings of the Eighth International Conference on Language Resources and Evaluation (LREC'12)

This paper describes the status of the standardization efforts of a Component Metadata approach for describing Language Resources with metadata. Different linguistic and Language & Technology communities as CLARIN, META-SHARE and NaLiDa use this component approach and see its standardization of as a matter for cooperation that has the possibility to create a large interoperable domain of joint metadata. Starting with an overview of the component metadata approach together with the related semantic interoperability tools and services as the ISOcat data category registry and the relation registry we explain the standardization plan and efforts for component metadata within ISO TC37/SC4. Finally, we present information about uptake and plans of the use of component metadata within the three mentioned linguistic and L&T communities.

Lexicon Schemas and Related Data Models: when Standards Meet Users
Thorsten Trippel | Michael Maxwell | Greville Corbett | Cambell Prince | Christopher Manning | Stephen Grimes | Steve Moran
Proceedings of the Sixth International Conference on Language Resources and Evaluation (LREC'08)

Lexicon schemas and their use are discussed in this paper from the perspective of lexicographers and field linguists. A variety of lexicon schemas have been developed, with goals ranging from computational lexicography (DATR) through archiving (LIFT, TEI) to standardization (LMF, FSR). A number of requirements for lexicon schemas are given. The lexicon schemas are introduced and compared to each other in terms of conversion and usability for this particular user group, using a common lexicon entry and providing examples for each schema under consideration. The formats are assessed and the final recommendation is given for the potential users, namely to request standard compliance from the developers of the tools used. This paper should foster a discussion between authors of standards, lexicographers and field linguists.

Building a historical corpus for Classical Portuguese: some technological aspects
Maria Clara Paixão de Sousa | Thorsten Trippel
Proceedings of the Fifth International Conference on Language Resources and Evaluation (LREC’06)

This paper describes the restructuring process of a large corpus of historical documents and the system architecture that is used for accessing it. The initial challenge of this process was to get the most out of existing material, normalizing the legacy markup and harvesting the inherent information using widely available standards. This resulted in a conceptual and technical restructuring of the formerly existing corpus. The development of the standardized markup and techniques allowed the inclusion of important new materials, such as original 16th and 17th century prints and manuscripts; and enlarged the potential user groups. On the technological side, we were grounded on the premise that open standards are the best way of making sure that the resources will be accessible even after years in an archive. This is a welcomed result in view of the additional consequence of the remodeled corpus concept: it serves as a repository for important historical documents, some of which had been preserved for 500 years in paper format. This very rich material can from now on be handled freely for linguistic research goals.

Feature-based Encoding and Querying Language Resources with Character Semantics
Baden Hughes | Dafydd Gibbon | Thorsten Trippel
Proceedings of the Fifth International Conference on Language Resources and Evaluation (LREC’06)

In this paper we discuss the explicit representation of character features pertaining to written language resources, which we argue are critically necessary in the long term of archiving language data. Much focus on the creation of language resources and their associated preservation is at the level of the corpus itself; however it is generally accepted that long term interpretation of these language resources requires more than a best practice data format. In particular, where language resources are created in linguistic fieldwork, and especially for minority languages, the need for preservation not only of the resource itself, but of additional metadata which allows for the resource to be accurately interpreted in the future is becoming a topic of research in itself. In this paper we extend earlier work on semantically based character decomposition to include representation of character properties in a variety of models, and a mechanism for exploiting these properties through queries.

A BLARK extension for temporal annotation mining
Dafydd Gibbon | Flaviane Romani Fernandes | Thorsten Trippel
Proceedings of the Fifth International Conference on Language Resources and Evaluation (LREC’06)

The Basic Language Resource Kit (BLARK) proposed by Krauwer is designed for the creation of initial textual resources. There are a number of toolkits for the development of spoken language resources and systems, but tools for second level resources, that is, resources which are the result of processing primary level speech resources such as speech recordings. Typically, processing of this kind in phonetics is done manually, with the aid of spreadsheets multi-purpose statistics software. We propose a Basic Language and Speech Kit (BLAST) as an extension to BLARK and suggest a strategy for integrating the kit into the Natural Language Toolkit (NLTK). The prototype kit is evaluated in an application to examining temporal properties of spoken Brazilian Portuguese.
