### LODEX ###
|
|
|
|
|
|
Lodex - Linked Open Data Extraction Tool enables to extract large ontology vocabularies out of unstructured data such as document text or social network messages.
|
|
|
|
|
|
It runs as service with preconfigured freebase and DBPedia vocabularies. Nevertheless, you can create own ontologies, according to your specific project needs.
|
|
|
|
|
|
Lodex is not a simple entity extractor. Special features are:
|
|
|
|
|
|
* adding arbitrary metatadata to an entity, not only recognizing entity types. (e.g. an id/URI)
|
|
|
* dealing with huge vocabularies with millions of entities
|
|
|
* find semantic entities according to label synonym lists, specified as part of your vocabulary
|
|
|
* statistic disambiguation, using text similarity against entity description texts, also specified as part of your vocabulary
|
|
|
* fuzzy match techniques such as Levenshtein, stopword resistent match, filtering high frequent terms with part of speech
|
|
|
* search for specific entity types. These also have to be specified as part of your entity metadata inside your vocabulary
