How to define co-occurrence in different domains of study?

This position paper presents a comparative study of co-occurrences. Some similarities and differences in the definition exist depending on the research domain (e.g. linguistics, NLP, computer science). This paper discusses these points, and deals with the methodological aspects in order to identify co-occurrences in a multidisciplinary paradigm.Comment: CICLING'2018 (International Conference on Computational Linguistics and Intelligent Text Processing) - March 18 to 24, 2018 - Hanoi, Vietnam (not published in CICLING proceedings
