LODDO: Using Linked Open Data Description Overlap to Measure Semantic Relatedness between Named Entities
[chapter]
2012
Lecture Notes in Computer Science
Preserved Fulltext
LOD consists of lots of data sources from different domains and provides rich a priori knowledge about the entities in the world. ...
the existing knowledge based approaches have the entity coverage issue and the statistical based approaches have unreliable result to low frequent entities, we propose a more comprehensive approach by leveraging ...
As DBpedia is extracted from Wikipedia, and Wikipedia has a larger coverage than WordNet, we can conclude that LOD does enlarge entity coverage tremendously than Wikipedia and WordNet. ...

The system implements four research contributions: it (1) executes n-ary relation extraction by applying the frame semantics linguistic theory, as opposed to binary techniques; it (2) simultaneously populates ...
We assess our approach by setting the target KB to DBpedia and by considering a use case of 52, 000 Italian Wikipedia soccer player articles. ...
Frames intrinsically bear n-ary relations through FEs, while RDF naturally represents binary relations. Hence, we need a method to express FEs relations in RDF, namely reification. ...

Using billions of page requests from Wikipedia's server logs, we measure how readers reach articles, how they transition between articles, and how these patterns combine into more complex navigation paths ...
We show that Wikipedia navigation paths commonly mesh with external pages as part of a larger online ecosystem, and we describe how naturally occurring navigation paths are distinct from targeted navigation ...
By analyzing billions of navigation traces extracted from the logs (Sec. 3), we span three levels of aggregation in our research questions: (1) Unigram level: How do readers reach Wikipedia articles? ...
