Conceptualization and Non-Relational Implementation of Ontological and Epistemic Vagueness of Information in Digital Humanities

2019. Inglés

Research in digital humanities often involves vague information, either because our objects of study lack clearly defined boundaries or because our knowledge about them is incomplete or hypothetical, which is especially relevant in disciplines about our past (such as history, archaeology or classical studies). Most techniques used to represent data vagueness emerged from natural sciences, and lack the expressiveness that would be ideal for humanistic contexts. Building on previous work, we present here a conceptual framework based on the ConML modelling language for the expression of information vagueness in digital humanities. In addition, we propose an implementation on nonrelational data stores, which are becoming popular within the digital humanities. Having clear implementation guidelines allow us to employ search engines or big data systems (commonly implemented using non-relational approaches) to handle the vague aspects of information. The proposed implementation guidelines have been validated in a real project, and show how we can query a vagueness-aware system without a large penalty in analytical and processing power.
