09:00 – 10:30 Content Analysis 1: Semantic Web and NLP
This tutorial is held by Sebastian Hellmann from the NLP2RDF Group at AKSW:
The NLP Interchange Format (NIF) is an RDF/OWL-based format that aims to achieve interoperability between Natural Language Processing (NLP) tools, language resources and annotations. NIF consists of specifications, ontologies and software (overview), which are combined under the version identifier “NIF 2.0″. Links:
11:00- 12:30 Content Analysis 2: Relation Extraction
In this tutorial, we will introduce the basic concepts of information extraction and relation extraction. Furthermore, we will explain the motivation of the machine learning methods for relation extraction task. As an example, we will demonstrate the DARE (domain adaptive relation extraction) system (http://dare.dfki.de) which shows how to learn relation extraction rules automatically from free natural language texts annotated with named entity and parsing information.
12:30 – 14:00 Lunch included
14:00 – 15:30 Content Analysis 3: Opinion Mining
In this tutorial, we will introduce the basic concepts of opinion mining and sentiment analysis. The addressed R&D topics are 1) development of linguistic resources for opinion mining, namely, automatic acquisition of sentiment words or subjective words and their orientations; 2) opinion mining at document or paragraph level: simple extraction of opinion holder, opinion target, subjectivity classification or sentiment classification; 3) opinion mining at feature level: identification of features (e.g., components of a car), construction of ontology for features, extraction of sentiments towards features, 4) comparative opinion mining: identification comparative sentences and extract comparative relations.
16:00 – 17:30 Content Analysis 4: Interactive session
Participants are invited to present their use cases, data, challenges and problems in lightning talks at the beginning of the session followed by a discussion about solutions and best practices.
