TL;DR: A way of representing product configuration knowledge using semantic web technology, namely OWL and SWRL, and developing actual configuration engines based on derived configuration knowledge, which enables the reuse of product configurationknowledge and thus facilitates the processes of modeling product configuration know.
Abstract: Effective and efficient development of product configuration systems, including the modeling of product configuration knowledge and the development of inference systems, is a key successful factor to implement mass customization paradigm. Ontology-based method for knowledge representation offers a means for the reuse and sharing of knowledge unambiguously. In this paper, we present a way of representing product configuration knowledge using semantic web technology, namely OWL and SWRL, and developing actual configuration engines based on derived configuration knowledge. Firstly, a general configuration ontology model defining vocabularies, terminologies and relationships that are common to the product configuration domain is constructed to act as a general semantic foundation for product configuration. With this general model, domain specific configuration models can be derived by inheriting or subclassing the ontologies within this general model. Both general ontology-based model and domain specific configuration model are formalized using OWL, an ontology language for encoding knowledge over the Web. Furthermore, constraint knowledge, such as require constraints and resource constraints, is represented with SWRL, a rule language based on OWL. Finally, actual configuration system is implemented using JESS by mapping OWL-based configuration knowledge and SWRL-based constraints into Jess facts and Jess, respectively. The presented ontology-based method for representing configuration knowledge enables the reuse of product configuration knowledge and thus facilitates the processes of modeling product configuration knowledge. In addition, the implementation of actual configuration system with existing rule engine, namely JESS, makes it possible the rapid development of product configuration systems.

TL;DR: This work has adapted, extended, and integrated several open source applications and frameworks that handle major portions of functionality for these platforms and includes an object-type repository, collaboration tools, an ability to identify and manage all key entities in the platform, and an integrated portal to manage diverse content and applications.
Abstract: As collaborative, or network science spreads into more science, engineering and medical fields, both the participants and their funders have expressed a very strong desire for highly functional data and information capabilities that are a) easy to use, b) integrated in a variety of ways, c) leverage prior investments and keep pace with rapid technical change, and d) are not expensive or timeconsuming to build or maintain. In response, and based on our accummulated experience over the last decade and a maturing of several key semantic web approaches, we have adapted, extended, and integrated several open source applications and frameworks that handle major portions of functionality for these platforms. At minimum, these functions include: an object-type repository, collaboration tools, an ability to identify and manage all key entities in the platform, and an integrated portal to manage diverse content and applications, with varied access levels and privacy options. At the same time, there is increasing attention to how researchers present and explain results based on interpretation of increasingly diverse and heterogeneous data and information sources. With the renewed emphasis on good data practices, informatics practitioners have responded to this challenge with maturing informatics-based approaches. These approaches include, but are not limited to, use case development; information modeling and architectures; elaborating vocabularies; mediating interfaces to data and related services on the Web; and traceable provenance. The current era of data-intensive research presents numerous challenges to both individuals and research teams. In environmental science especially, sub-fields that were data-poor are becoming data-rich (volume, type and mode), while some that were largely model/ simulation driven are now dramatically shifting to data-driven or least to data-model assimilation approaches. These paradigm shifts make it very hard for researchers used to one mode to shift to another, let alone produce products of their work that are usable or understandable by non-specialists. However, it is exactly at these frontiers where much of the exciting environmental science needs to be performed and appreciated.

TL;DR: DAMLJessKB will become one in a suite of tools that let users truly leverage the shared semantics of the Semantic Web, as more and more Web sites, network services, databases, and knowledge bases look to DAML as a de facto representation syntax.
Abstract: Fully realizing the Semantic Web vision will require practical tools. We believe that DAMLJessKB is one such tool. As more and more Web sites, network services, databases, and knowledge bases look to DAML as a de facto representation syntax, we hope that DAMLJessKB will become one in a suite of tools that let users truly leverage the shared semantics.
