    • Adding Semantics to Social Websites for Citizen Science 

      Parafiynyk, Andriy; Parr, Cynthia; Sachs, Joel; Finin, Tim (AAAI, 2007-06-05)
      While efforts are underway to represent existing ecological databases semantically, so that they may be intelligently queried and integrated by agents, less attention has been paid to 1) rapidly changing datastreams, and ...
    • Bioblitz Data on the Semantic Web 

      Sachs, Joel; Han, Lushan; Wang, Taowei; Parr, Cynthia (2008-09-30)
      Last summer, we represented the 1200 species observations of the First Annual Blogger Bioblitz in RDF. This allowed us to easily integrate the data with existing RDF data on natural history, taxonomy, food webs, conservation ...
    • Enabling Semantic Ecoblogging and Bioblitzes 

      Parr, Cynthia; Wang, Taowei; Sachs, Joel; Han, Lushan; Finin, Timothy (University of Maryland, College Park, 2008-05-30)
      People currently create Eco-blogs: stories about wildlife they have seen or observations they've made. Similarly, citizen and scientists work together on Bioblitzes to comprehensively report as many species as possible ...
    • ETHAN: the Evolutionary Trees and Natural History Ontology 

      Parr, Cynthia; Sachs, Joel; Parafiynyk, Andriy; Wang, Taowei; Espinosa, Roger (University of Maryland, Baltimore County, 2006-11-01)
      Large-scale ecological modeling and evolutionary studies often rely on scoring taxon-level characteristics of a wide variety of organisms. Compiling such data is laborious and may involve finding and reformatting data ...
    • Integrating Ecoinformatics Resources on the Semantic Web 

      Parr, Cynthia; Parafiynyk, Andriy; Sachs, Joel; Ding, Li; Dornbush, Sandor; Finin, Tim; Wang, Taowei; Hollender, Allan (2006-05-20)
      We describe ELVIS (the Ecosystem Location Visualization and Information System), a suite of tools for constructing food webs for a given location. We express both ELVIS input and output data in OWL, thereby enabling its ...
    • RDF123: a mechanism to transform spreadsheets to RDF 

      Han, Lushan; Parr, Cynthia; Sachs, Joel; Joshi, Anupam; Finin, Tim (2007-08-17)
      We describe RDF123, a highly flexible open-source tool for transforming spreadsheet data to RDF. Existing spreadsheet-to-RDF tools typically map only to star-shaped RDF graphs, i.e. each spreadsheet row is an instance, ...
    • Social and Semantic Computing in Support of Citizen Science 

      Sachs, Joel; Finin, Tim (2011-08-05)
      We describe our ongoing work on using social media as a platform for citizen science. Building on our previous work of facilitating citizen science observations, and using RDF to integrate them with existing biodiversity ...
    • Swoogle: A Search and Metadata Engine for the Semantic Web 

      Ding, Li; Finin, Tim; Joshi, Anupam; Pan, Rong; Cost, R. Scott; Peng, Yun; Reddivari, Pavan; Doshi, Vishal C.; Sachs, Joel (ACM, 2004-11-09)
      Swoogle is a crawler-based indexing and retrieval system for the Semantic Web, i.e., for Web documents in RDF or OWL. It extracts metadata for each discovered docu- ment, and computes relations between documents. ...
    • Using the Semantic Web to Integrate Ecoinformatics Resources 

      Parr, Cynthia; Parafiynyk, Andriy; Sachs, Joel; Pan, Rong; Han, Lushan; Ding, Li; Finin, Tim; Wang, David (AAAI, 2006-07-18)
      We demonstrate an end-to-end use case of the semantic web’s utility for synthesizing ecological and environmental data. ELVIS (the Ecosystem Location Visualization and Information System) is a suite of tools for ...
    • Using the Semantic Web to Support Ecoinformatics 

      Sachs, Joel; Parr, Cynthia; Parafiynyk, Andriy; Pan, Rong; Han, Lushan; Ding, Li; Finin, Tim; Hollender, Allan; Wang, David (AAAI, 2006-10-13)
      We describe our on-going work in using the semantic web in support of ecological informatics, and demonstrate a distributed platform for constructing end-to-end use cases. Specifically, we describe ELVIS (the Ecosystem ...
    • What Does it Mean for a URI to Resolve 

      Sachs, Joel; Finin, Tim (AAAI, 2010-03-22)
      Amongst the best practices that constitute Linked Data, one of the foremost is to use only HTTP-URIs as identifiers for RDF resources. This is so that the URI will resolve in a Linked Data browser to give information about ...
