To account for sociodemographics in models of individual annotator behaviour, we introduce group-specific layers to multi-annotator models.

Predicting Disease-Gene Associations using Cross-Document Graph-based Features

no code implementations26 Sep 2017 Hendrik ter Horst, Matthias Hartung, Roman Klinger, Matthias Zwick, Philipp Cimiano

In the context of personalized medicine, text mining methods pose an interesting option for identifying disease-gene associations, as they can be used to generate novel links between diseases and genes which may complement knowledge from structured databases.

Aspect-Based Relational Sentiment Analysis Using a Stacked Neural Network Architecture

1 code implementation19 Sep 2017 Soufian Jebbara, Philipp Cimiano

We present a novel neural architecture for sentiment analysis as a relation extraction problem that addresses this problem by dividing it into three subtasks: i) identification of aspect and opinion terms, ii) labeling of opinion terms with a sentiment, and iii) extraction of relations between opinion terms and aspect terms.

Evaluating Architectural Choices for Deep Learning Approaches for Question Answering over Knowledge Bases

no code implementations6 Dec 2018 Sherzod Hakimov, Soufian Jebbara, Philipp Cimiano

We address the task of answering simple questions, consisting in predicting the subject and predicate of a triple given a question.

Learning Diachronic Analogies to Analyze Concept Change

1 code implementation COLING 2018 Matthias Orlikowski, Matthias Hartung, Philipp Cimiano

We show that a model which treats the concept terms as analogous and learns weights to compensate for diachronic changes (weighted linear combination) is able to more accurately predict the missing term than a learned transformation and two baselines for most of the evaluated concepts.

The Open Linguistics Working Group (OWLG) brings together researchers from various fields of linguistics, natural language processing, and information technology to present and discuss principles, case studies, and best practices for representing, publishing and linking linguistic data collections.

Crowdsourcing Ontology Lexicons

no code implementations LREC 2016 Bettina Lanser, Christina Unger, Philipp Cimiano

In order to make the growing amount of conceptual knowledge available through ontologies and datasets accessible to humans, NLP applications need access to information on how this knowledge can be verbalized in natural language.

Terme-\`a-LLOD: Simplifying the Conversion and Hosting of Terminological Resources as Linked Data

no code implementations LREC 2020 Maria Pia di Buono, Philipp Cimiano, Mohammad Fazleh Elahi, Frank Grimm

While we apply this paradigm to the transformation and hosting of terminologies as linked data, the paradigm can be applied to any other resource format as well.

Structured Prediction for Joint Class Cardinality and Entity Property Inference in Model-Complete Text Comprehension

no code implementations EMNLP (spnlp) 2020 Hendrik ter Horst, Philipp Cimiano

We show that cardinality prediction can successfully be approached by modeling the overall task as a joint inference problem, predicting the number of individuals of certain classes while at the same time extracting their properties.

Insights from an OTTR-centric Ontology Engineering Methodology

Furthermore, we find that because OTTR templates encapsulate modeling decisions, the engineering process becomes flexible, meaning that design decisions can be changed at little cost.

Architectural Sweet Spots for Modeling Human Label Variation by the Example of Argument Quality: It's Best to Relate Perspectives!

1 code implementation6 Nov 2023 Philipp Heinisch, Matthias Orlikowski, Julia Romberg, Philipp Cimiano

To best represent the interplay of individual and shared perspectives, we consider a continuum of approaches ranging from models that fully aggregate perspectives into a majority label to "share nothing"-architectures in which each annotator is considered in isolation from all other annotators.
