Hypermedia-based discovery for source selection using low-cost linked data interfaces

Evaluating federated Linked Data queries requires consulting multiple sources on the Web. Before a client can execute queries, it must discover data sources, and determine which ones are relevant. Federated query execution research focuses on the actual execution, while data source discovery is often marginally discussed-even though it has a strong impact on selecting sources that contribute to the query results. Therefore, the authors introduce a discovery approach for Linked Data interfaces based on hypermedia links and controls, and apply it to federated query execution with Triple Pattern Fragments. In addition, the authors identify quantitative metrics to evaluate this discovery approach. This article describes generic evaluation measures and results for their concrete approach. With low-cost data summaries as seed, interfaces to eight large real-world datasets can discover each other within 7 minutes. Hypermedia-based client-side querying shows a promising gain of up to 50% in execution time, but demands algorithms that visit a higher number of interfaces to improve result completeness

Using the Annotated Bibliography as a Resource for Indicative Summarization

We report on a language resource consisting of 2000 annotated bibliography entries, which is being analyzed as part of our research on indicative document summarization. We show how annotated bibliographies cover certain aspects of summarization that have not been well-covered by other summary corpora, and motivate why they constitute an important form to study for information retrieval. We detail our methodology for collecting the corpus, and overview our document feature markup that we introduced to facilitate summary analysis. We present the characteristics of the corpus, methods of collection, and show its use in finding the distribution of types of information included in indicative summaries and their relative ordering within the summaries.Comment: 8 pages, 3 figure

Facilitating professional engagement with planning research

The context for this project is the limited connectivity between applied planning research and professional planning practice. The planning profession, by its very nature, is continually developing plans, policies and strategies to guide place-based management and development. An assumption guiding the research is that sound evidence is useful if not essential to inform good planning practice. This assumption does not hold for all planning practice - statutory planning and other policy implementation activities are, for example, largely informed by existing policy frameworks. However, in most strategic planning or policy development contexts (including statutory reform), an argument for the relevance of an evidence base can be made. While not all research aims to directly inform practice – such as research of a conceptual or theoretical nature – there is a significant amount of applied urban research produced that has discernible implications for policy and practice. Unfortunately, much of the research base that could inform and improve professional planning practice is difficult to access. There are also other barriers to knowledge exchange, including limited professional engagement with research outputs; and limited or poorly tailored research outputs for a professional audience. This project aims to provide recommendations on how to better connect Australian urban planning practice to the evidence base within urban planning research outputs. To do so the project explores barriers to, and opportunities for, better connecting professional planning practice with applied planning research
