I From Mentions to Ontology: A Pilot Study

by Octavian Popescu, Bernardo Magnini, Emanuele Pianta, Luciano Serafini, Manuela Speranza
"... Abstract — In this paper we propose a pilot study aimed at an indepth comprehension of the phenomena underlying Ontology Population from text. The study has been carried out on a collection of Italian news articles, which have been manually annotated at several semantic levels. More specifically, we ..."

Ontology Population from Textual Mentions: Task Definition and Benchmark

by Bernardo Magnini, Emanuele Pianta, Octavian Popescu, Manuela Speranza
"... In this paper we propose and investigate Ontology Population from Textual Mentions (OPTM), a sub-task of Ontology Population from text where we assume that mentions for several kinds of entities (e.g. PERSON, ORGANIZATION, LOCATION, GEO-POLITICAL _ ENTITY) are already extracted from a document colle ..."

Identifying Untyped Relation Mentions in a Corpus given an Ontology

by Gabor Melli
"... In this paper we present the SDOIrmi text graph-based semi-supervised algorithm for the task for relation mention identification when the underlying concept mentions have already been identified and linked to an ontology. To overcome the lack of annotated data, we propose a labelling heuristic based ..."

Concept Mentions within KDD2009 Abstracts (kdd09cma1) Linked to a KDD Ontology (kddo1

by Gabor Melli - In: Proceedings of the 7th International Conference on Language Resources and Evaluation (LREC , 2010
"... We introduce the kddo1 ontology and semantically annotated kdd09cma1 corpus from the field of knowledge discovery in database (KDD) research. The corpus is based on the abstracts for the papers accepted into the KDD-2009 conference. Each abstract has its concept mentions identified and, where possib ..."

Y.: Foam - framework for ontology alignment and mapping; results of the ontology alignment initiative

by Marc Ehrig - Proceedings of the Workshop on Integrating Ontologies. Volume 156., CEUR-WS.org (2005) 72–76 , 2005
"... This paper briefly introduces the system FOAM and its underlying techniques. We then discuss the results returned from the evaluation. They were very promising and at the same time clarifying. Concisely: labels are very important; structure helps in cases where labels do not work; dictionaries may p ..."

, i.e. select excerpts of the overall ontology definition to describe a specific. This includes individual features, e.g. labels, structural features, e.g. subsumption, but also more complex features as used in OWL, e.g. restrictions. 2. Search Step Selection, i.e. choose two entities from the two

From being ontologically serious to serious ontology

by Michael Esfeld , 2006
"... The paper first argues that if one takes current fundamental physics seriously, one gets to a metaphysics of events and relations in contrast to substances and intrinsic properties. Against that background, the paper discusses Heil’s theory of properties being both categorical and dispositional and ..."
Abstract - Add to MetaCart
In this paper, I shall take the liberty to simply pin down a few central issues that arise in constructing a comprehensive metaphysics, basing myself on some of the discussions in the preceding papers. I shall first mention my methodological background of metaphysics grounded on science, then consider Heil’s

Reconstructing the Ontology of the Tang Dynasty A pilot study of the Shakespearean-garden approach

by unknown authors
"... We propose the Shakespearean-garden approach towards domain ontology construction in this paper. In sum, we suggest that domain lexica can be extracted and obtained for non-standard knowledge backgrounds. Once the comprehensive lexica are collected, a lexical interface between wordnet and our Sinica ..."

Ontology and Information Systems

by Barry Smith
"... Abstract. The term 'formal ontology' was first used by the philosopher Edmund Husserl in his Logical investigations to signify the study of those formal structures and relations -above all relations of part and whole -which are exemplified in the subject-matters of the different material ..."

Smith I Basic Concepts of Formal Ontology imagine a band of colour that is subject to a gradual transition from red through orange to yellow, then each region of this band is fused with its immediately adjacent regions. In the field of what is experienced perceptually, then, we

A semantic assistant for mutation mentions in PubMed abstracts.

by Jonas B Laurila, Re Kouznetsov, Christopher J O Baker
"... Biomedical researchers consume and analyze PubMed abstracts on a daily basis seeking to update their existing knowledge with insights from newly published literature.

Semi-Automatic Ontology Extension Using Spreading Activation

by Wei Liu, Albert Weichselbraun, Arno Scharl, Elizabeth Chang
"... Abstract: This paper describes a system to semi-automatically extend and refine ontologies by mining textual data from the Web sites of international online media. Expanding a seed ontology creates a semantic network through co-occurrence analysis, trigger phrase analysis, and disambiguation based o ..."
