Applications are invited for a 1.5 year position as postdoctoral researcher within the research project “Graphs and Ontologies for Literary Evolution Models” (GOLEM), financed by an ERC Starting Grant and coordinated by the Principal Investigator (PI), dr. Federico Pianzola.

Millions of stories are shared on online platforms such as Wattpad, AO3, and, combined with readers’ reactions and comments on these stories. The GOLEM project will analyze stories and their responses gathered from sites in five different languages – English, Spanish, Italian, Korean and Indonesian. This analysis can provide a wealth of information about the characters in a story, the genre, what a story is about, how a story is constructed, what themes are covered, as well as what readers from different countries and cultures find important in a story.

What elements in a story are meaningful to the reader? What makes a story get read, and what do readers value in a story? The information we collect with this research makes it possible, with the help of computer models, to find answers to these kinds of questions. The goal is to test hypotheses about cultural evolution and develop a methodology that can also be applied to books from other periods in history. In this way, we can study the evolution of fiction over the centuries, and gain unprecedented insight into something as old as humanity itself: storytelling
The core infrastructure of the project will be a graph database of metadata from ca. 10 million stories, including information extracted from the full text of the stories via NLP techniques.
The project will hire a postdoctoral researcher, who will work together with the PI, a database technician, and two PhD students.
Your tasks
In collaboration with the PI and a technician, you will work on the definition of an ontology and creation of a graph database compatible with Wikidata and other projects about the digitization of literary texts.

You will contribute to:

  • define the ontology to be used throughout the project
  • organize data in a local database
  • set up and maintain a triple store with extracted metadata
  • ensure communication between the local database and the triple store with a public SPARQL endpoint
  • enrich the triple store with information obtained via rule-based and graph reasoning techniques
  • disseminate the project’s activities.
