Hi everyone, I’m Linh Hoang, from project 3. This week, my co-intern and I focused on creating a YesWorkflow Data Model with our own vocabulary. Previously, we used ProvONE Data Model (which is an extension of the standard Provenance Data Model recommended by W3C) to represent items of YesWorkflow. However, Continue reading Prospective and Retrospective Provenance Queries: Week 4 – YesWorkflow Data Model
Hi everyone, It’s Linh Hoang from Project 3. This week, I spent most of my time to read papers and also ran some experiments to explore SPARQL recursive queries capability. The objective is to be able to run standard recursive queries in SPARQL. We found “property path” is a way Continue reading Prospective and Retrospective Provenance Queries: Week 3 – SPARQL Recursive Queries
This is the third week of my internship. I felt much comfortable to work with the professors and my co-partner. We basically made progress in schedule. For this week, given the elementary model structure in RDF/Turtle file for simulate_data_collection example of YesWorkflow, I further improved the RDF/Turtle data model by Continue reading Week-3-Update
Hi all, It’s Linh Hoang from Project 3. This week, I am working on exploring SPARQL querying capabilities in YesWorkflow. The objective is to testing how well SPARQL can query YW outputs, which are represented in RDF format. First, I completed installing Virtuoso on my machine and wrote a manual of Continue reading Prospective and Retrospective Provenance Queries: Week 2 – SPARQL Provenance Query
During the second week, Linh and I dug into RDF/Turtle format and SPARQL syntax for testing the existing incomplete Turtle file (refer to Prefix rdf, rdfs, provone, owl and self-defined yw) and relevant queries. I successfully installed Apahe-Jena on my Windows machine and tested the five existing simple SPARQL queries Continue reading Week-2-Update
This is my first week for DataONE summer intern. I am glad to meet the mentors Bertram Ludaescher, Timothy McPhillips and Paolo Missier. I am also happy to work on the project with another intern, Linh Hoang, who is a PhD student in iSchool of UIUC. She is warm-hearted and Continue reading Week-1-Update
My first week internship at DataOne started with a meeting with my mentors Prof. Bertram Ludaescher, Timothy McPhillips and Paolo Missier and my co-intern Hui Lyu. We discussed about what are the objectives of the internship and came up with a list of tasks for the next following weeks. Overall, the objective of the internship is to reimplement existing Continue reading Prospective and Retrospective Provenance Queries: Get to know YesWorkflow
We are excited to begin work with our 2017 cohort of summer interns across a range of projects. Information about the projects can be found on our internship description page. Our interns will start recording their activities, experiences and results in this space starting May 2017.
