DAFOE: a Platform for Building Ontologies from Texts
نویسندگان
چکیده
Although text-based ontology engineering gained much popularity in the last 10 years, very few ontology engineering platforms exploit the full potential of the connection between texts and ontologies. We propose DAFOE, a new platform for building ontologies with a terminological component using different types of linguistic entries (text corpora, results of natural language processing tools, terminologies or thesauri). DAFOE supports knowledge structuring and conceptual modelling from these linguistic entries as well as ontology formalization. DAFOE outputs models with two main original features: an ontology articulated with a lexical component and a connection with the text or linguistic entry that motivated their definition.

Incremental Design of Ontologies - A Model Transformation-based Approach
This paper focuses on Model Driven Engineering (MDE) techniques to build ontology incrementally. The global building process consists of building ontologies from texts through a stepwise approach. Our approach consists of modeling each step independently and defining a mapping model to express relationships between these steps. Results of this work are applied in the ANR DAFOE project, which ai...
متن کاملDAFOE: A Multimodel and Multimethod Platform for Building Domain Ontologies∗
The concept of ontologies, appeared in the nineties, constitute a key point to represent and share the meaning carried by formal symbols. Yet building of such an ontology is quite difficult. A way to do so is to use preexistent elements (textual corpus, taxonomies, norms or other ontologies) and operate them as a basis to define the field ontology. Still, there is neither accepted process nor s...
متن کاملDaFOE : an Ontology Building Platform From Texts or Thesauri?
La construction d'ontologies à partir de textes fait l'objet d'études depuis plusieurs années dans le domaine de l'ingénierie des ontologies (Terminae Aussenac-Gilles et al. (2000), Text2Onto Cimiano & Volker (2005)). Un cadre méthodologique en quatre étapes (constitution d'un corpus de documents, analyse linguistique du corpus, conceptualisation, opérationnalisation de l'ontologie) est commun ...
متن کاملFrom Linguistics to Ontologies - The Role of Named Entities in the Conceptualisation Process
Ontologies that have been built from texts can be associated with lexical information that is crucial for the semantic annotation of texts and all semantic search tasks. However, the entire pocess of building ontologies from texts cannot be fully automated and it is important to guide the knowledge engineer during the building process. This paper presents an enriched version of TERMINAE, which ...

Extracting structured information about entities from web texts is an important task in web mining, natural language processing, and information extraction. Information extraction is useful in many applications including search engines, question-answering systems, recommender systems, machine translation, etc. An information extraction system aims to identify the entities from the text and extr...
