PIA-Core: Semantic Annotation through Example-based Learning
نویسندگان
چکیده
This paper summarizes the aims and scope of the PIA (Portable Information Access) project’s PIA-Core system for automatic annotation of documents on the Semantic Web, i.e. the next generation World Wide Web. The focus of the project is to develop a portable information extraction system that can be easily adapted to new domains. PIA has its foundations on three resources: the PIA-Core information extraction module, application modules and PIA guidelines for ensuring consistent annotation. We are currently developing PIA-Core based on advanced machines learning methods to automatically annotate documents with terminology, names, temporal and quantity expressions etc. using examples of annotated documents.

The PIA Project: Learning to Semantically Annotate Texts from an Ontology and XML-Instance Data
The development of the XML and RDF(S) standards offer a positive environment for machine learning to enable the automatic XML-annotation of texts that can encourage the extension of Semantic Web applications. After reviewing the current limitations of information extraction technology, specifically its lack of portability to new domains, we introduce the PIA project for automatically XML-annota...

The Effects of Multimedia Annotations on Iranian EFL Learners’ L2 Vocabulary Learning
In our modern technological world, Computer-Assisted Language learning (CALL) is a new realm towards learning a language in general, and learning L2 vocabulary in particular. It is assumed that the use of multimedia annotations promotes language learners’ vocabulary acquisition. Therefore, this study set out to investigate the effects of different multimedia annotations (still picture annotatio...

In this paper, we describe our participation in the ImageCLEF 2015 Scalable Concept Image Annotation task. In this participation, we display our approach for an automatic image annotation by the use of an ontology-based semantic hierarchy handled at both learning and annotation steps. While recent works focused on the use of semantic hierarchies to improve concept detector accuracy, we are inve...
متن کامل1iASA: Learning to Annotate the Semantic Web
With the advent of the Semantic Web, there is a great need to upgrade existing web content to semantic web content. This can be accomplished through semantic annotations. Unfortunately, manual annotation is tedious, time consuming and error-prone. In this paper, we propose a tool, called iASA, that learns to automatically annotate web documents according to an ontology. iASA is based on the com...
