Summary of progress

This period we continued the work on the further adoption of GF in the Business Process Platform of Be Informed. On of our goals to leverage the adoption of GF was to create a framework in which models could automatically be verbalized. Domain experts usually do not have a background in modeling and thus checking whether a rule or law is modeled correctly usually proves to be a difficulty for them. Be Informed wants to take away these barriers by creating verbalizations of their models. These verbalizations however should not be only a textual representation the models, but it wants the possibility to create verbalizations of the same models for a set of the distinguished tasks.

In order to do this Be Informed created the 3D framework together with the University of Bielefeld. An article on this work will be published in "Jeroen van Grondelle, Christina Unger: A 3-Dimensional Paradigm for Conceptually-scoped Language Technology" in Towards the Multilingual Semantic Web, Paul Buitelaar and Philip Cimiano, eds., Springer, Heidelberg, Germany, 2013. This orthogonal modularization supports specification of the conceptualization and lexical information per dimension, i.e. specifying domains independent from tasks and vice versa. The dimensions can then be freely combined by choosing the particular domains, tasks and languages supported for a specific application.

While the task grammars are written once by hand, each of the domain grammars is created automatically from a Be Informed or OWL ontology and plugged right into the grammars already created for the framework. In order to create these domain grammar automatically Be Informed created three verbalizers, each one with its own heuristics to create verbalizations.

In an evaluation the likelihood of the verbalizations created with grammars from these verbalizers were compared to the verbalizations created by the velocity templates, the verbalizer which is currently implemented in the Be Informed product suite. The results show that the GF based verbalizers are better than these velocity verbalizers.

Work on the adoption and evaluation has been finished and reported in D12.2 (http://www.molto-project.eu/biblio/deliverable/d122-user-studies-bis-exp...).
