Design Patterns for Engineering the Ontology-Lexicon Interface [chapter]

John P. McCrae, Christina Unger
2014 Towards the Multilingual Semantic Web  
We exemplify this with the use case of constructing a lexicon for the DBpedia ontology.  ...  We combine both to develop the first set of design patterns for ontology-lexica, using the ontology-lexicon model, lemon.  ...  This work has led to the creation of the first lemon lexicon for DBpedia, available at (Unger, et al. 2013) .  ...

A Corpus-Based Approach for the Induction of Ontology Lexica [chapter]

Sebastian Walter, Christina Unger, Philipp Cimiano
2013 Lecture Notes in Computer Science  
While there are lexicon models such as lemon allowing to define a lexicon for a given ontology, the cost involved in creating and maintaining such lexica is substantial, requiring a high manual effort.  ...  by extracting dependency paths that can be used as a basis to create lemon lexicon entries.  ...  For example, for the class http://dbpedia. org/ontology/Activity with label activity, we find the additional synonym action, thus leading to the following two entries in the lemon lexicon 10 : 1 : activity  ...

ATOLL—A framework for the automatic induction of ontology lexica

Sebastian Walter, Christina Unger, Philipp Cimiano
2014 Data & Knowledge Engineering  
While ontology lexicon models like lemon allow for defining such linguistic information with respect to a given ontology, the cost involved in creating and maintaining such lexica is substantial, requiring  ...  We instantiate ATOLL with respect to DBpedia as dataset and Wikipedia as corresponding corpus, and evaluate it by comparing the automatically generated lexicon with a manually constructed one.  ...  For example, an entry for the DBpedia class Star could look as follows: : star a lemon : Word ; lemon : canonicalForm [ lemon : writtenRep " star " @en ]; lemon : sense [ lemon : reference dbpedia : Star  ...

Gennaro Nolano, Mohammad Fazleh Elahi, Maria Pia di Buono, Philipp Cimiano
2022 Zenodo  
We use a model-based approach to question answering based on an ontology lexicon in lemon format.  ...  We apply the approach for the Italian language and implement a question answering system that can answer more than 1.6 million questions over the DBpedia knowledge graph.  ...  Results We apply our system to the DBpedia dataset and manually created a lemon lexicon comprising of 249 lexical entries 8 .  ...

Lexical Meaning Formal Representations Enhancing Lexicons and Associated Ontologies

Maria Gritz
2018 International Conference of the Italian Association for Artificial Intelligence  
The technique is integrated within the Ontolex-Lemon lexicon model by supplying a lexical concept of an ontology class with a description logic based formal definition.  ...  DL-based and graph-based lexical meaning formal representations are applied for lexical sense disambiguation within a lexicon and for extension of class and property taxonomies of an associated ontology  ...  As a result, the DBpedia class Agent was set as an ontological restriction for a syntactic argument associated with the range of the property hasBeneficiary (SpeechAct, Thing).  ...
