DBpedia to Wikidata: Exploring the Linked Jazz Name Directory<\/p>\n
LIS-664 – Program for Cultural Heritage, Fall 2016, Pratt Institute<\/p>\n
This project was informed by my involvement in Pratt’s long-running Linked Jazz<\/a> project, which seeks to explore the relationships and collaborations between jazz musicians by extracting relationship data from oral history transcripts and publishing it as semantically-structured linked data<\/a>. Linked Jazz recently received a grant from the New Orleans Jazz and Heritage Foundation<\/a> to create a dataset focused specifically on New Orleans-based jazz musicians. As a\u00a0test project for this grant, I wanted to explore what familial relationship data about New Orleans-based jazz musicians was available on Wikidata<\/a>, a popular linked data repository. I also wanted to compare Wikidata to another popular linked data dataset, DBpedia<\/a>, which was used during the creation of the Linked Jazz dataset in 2011, but which has been increasingly supplanted by Wikidata in the succeeding six years.<\/p>\n View Project Website<\/a> – Download Project Presentation<\/a><\/p>\n I started by downloading the original Linked Jazz Name Directory<\/a>, available online as an N-Triple file<\/a>. This directory includes the names of about 9,000 jazz musicians along with their persistent resource identifiers<\/a> on DBpedia. To find the equivalent identifiers for these musicians on Wikidata, I first had to separate these names out into JSON<\/a> using a Python<\/a> script. Because resources on DBpedia (see example<\/a>) contain links to the identifier for the same person, place, or thing on other linked data repositories, I could then use another Python script to extract the corresponding Wikidata ID for each name in the Linked Jazz Directory. With these names, I used another script to query Wikidata for the place of birth<\/a> and place of death<\/a> of each musician. Using even more scripts, I narrowed down the directory to only musicians who had been born in or died in New Orleans. I then attempted to query Wikidata for information about the relatives of these individuals<\/a>, but was not able to find much data. Because I already had data on where musicians in the Linked Jazz Directory were born and\/or had died, I decided to experiment with the\u00a0Tableau<\/a> software platform to create a geomapped visualization<\/a> of these locations.<\/p>\n I worked on this project alone, but used scripts created by Molly Reese-Lerner and fellow Linked Jazz team member Hannah Sistrunk for an LIS-664-01 project the previous year<\/a>, along with scripts created by Linked Jazz project member and METRO Fellow Karen Li-Lun Hwang, <\/a> as the basis of many of the scripts I used.<\/p>\n Technology<\/p>\n This project was primarily based on Python programming. I also worked with data serialization formats including N-Triples and JSON, semantic web datasets, and data visualization software.<\/p>\n Communication<\/p>\n Using Tableau, I created an interactive visualization of the jazz musician birth and death data I pulled from Wikidata.<\/p>\n Reflective Practice<\/p>\n This project was in part meant to examine Wikidata as a replacement source for DBpedia, and to explore trends in the use of linked data datasets as a whole.<\/p>\n","protected":false},"excerpt":{"rendered":" Project Title: DBpedia to Wikidata: Exploring the Linked Jazz Name Directory Course: LIS-664 – Program for Cultural Heritage, Fall 2016, Pratt Institute Project Description: This project was informed by my involvement in Pratt’s long-running Linked Jazz project, which seeks to explore the relationships and collaborations between jazz musicians by extracting relationship data from oral history […]<\/p>\n","protected":false},"author":1,"featured_media":1722,"parent":1603,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"ngg_post_thumbnail":0,"footnotes":""},"class_list":["post-1476","page","type-page","status-publish","has-post-thumbnail","hentry"],"yoast_head":"\nProject Documentation<\/h4>\n
