GATE Teamware: a web-based, collaborative text annotation framework

Abstract: This paper presents GATE Teamware--an open-source, web-based, collaborative text annotation framework. It enables users to carry out complex corpus annotation projects, involving distributed annotator teams. Different user roles are provided (annotator, manager, administrator) with customisable user interface functionalities, in order to support the complex workflows and user interactions that occur in corpus annotation projects. Documents may be pre-processed automatically, so that human annotators can begin with text that has already been pre-annotated and thus making them more efficient. The user interface is simple to learn, aimed at non-experts, and runs in an ordinary web browser, without need of additional software installation. GATE Teamware has been evaluated through the creation of several gold standard corpora and internal projects, as well as through external evaluation in commercial and EU text annotation projects. It is available as on-demand service on GateCloud.net, as well as open-source for self-installation.

Process-Structure Linkages Using a Data Science Approach: Application to Simulated Additive Manufacturing Data

Abstract: A novel data science workflow is developed and demonstrated to extract process-structure linkages (i.e., reduced-order model) for microstructure evolution problems when the final microstructure depends on (simulation or experimental) processing parameters. This workflow consists of four main steps: data pre-processing, microstructure quantification, dimensionality reduction, and extraction/validation of process-structure linkages. Methods that can be employed within each step vary based on the type and amount of available data. In this paper, this data-driven workflow is applied to a set of synthetic additive manufacturing microstructures obtained using the Potts-kinetic Monte Carlo (kMC) approach. Additive manufacturing techniques inherently produce complex microstructures that can vary significantly with processing conditions. Using the developed workflow, a low-dimensional data-driven model was established to correlate process parameters with the predicted final microstructure. Additionally, the modular workflows developed and presented in this work facilitate easy dissemination and curation by the broader community.

End user oriented workflow approach including structured processing of ad hoc workflows with a collaborative process engine

Abstract: In a structured workflow system, a configurable workflow engine provides mechanisms for executing and scheduling the work items in a defined way. End users use their discretion and define their own “local” processes and “local” rules for processing work items, or deviate from predefined processes. The configurable workflow engine might be installed at a server to organize workflows and business processes where end users can define processing steps for incoming work items by setting up rules and defining workflows as part of a local workflow structure. By defining these rules and workflows, the further processing steps of future incoming work items can be automated. When an administrator directs the workflow engine to move from a current phase to a next phase, the workflow engine deals with the incomplete items by allowing the administrator to carry over work items (or might do it automatically). End -user consultation might be included in the carry-over decisions. The carried over work items are added as parallel activities to the next phase. The workflow engine handles imposing and executing control flow dependencies between tasks, thus providing a smooth transition from totally unstructured work to semi-structured or completely structured work. When the workflow engine encounters semantically correlated work items/tasks, the process engine assumes that these work items/tasks belong to the same process instance.

Integrating Semantic and Syntactic Descriptions to Chain Geographic Services

Abstract: Integrating multiple geographic services from different information communities and spatiolinguistic regions is challenging because of its inherent complexity and heterogeneity. A geographic information systems workflow approach can use semantic and syntactic service descriptions to form service chains that can integrate service discovery, composition, and reuse. Service chaining links remote geographic services to help expert users form complex geoprocessing services and perform timely analysis of geodata. This method facilitates the use of XML-based service description languages to build a geoservice-reuse architecture based on common ontologies and shared service descriptions
