Querying the YAGO ontology Simple query – only extract concepts from Yago (Example: Museum) Complex query – we extract S-V-O and we use the subject to extract concepts from Yago (Example: tennis players born after 1980) We search connections between subject and WordNet concepts or Wikipedia categories Then, verb and object are used in filtering process 17 Iasi, 13 January, 2020 Iftene, A., Baboi, A.M. 2016.

- 18. Choosing which YAGO entities to use in crawling Flickr database The problem: in YAGO ontology we have thousands of instances for concepts. So, which instances to select from these? Solution 1: we use Google and performed parallel searches for every concept and select the concepts using “number of pages returned” – time consuming Solution 2: we use a parameter from YAGO which keep the size of Wikipedia page for a specific instance – very fast and very good quality 18 Iasi, 13 January, 2020
