Predicting independent living outcomes from written reports of social workers

no code implementations EMNLP (NLP+CSS) 2020 Angelika Maier, Philipp Cimiano

To support this task, we present an approach that extracts indications of independence on different life aspects from the day-to-day documentation that social workers create.

Explainable Unsupervised Argument Similarity Rating with Abstract Meaning Representation and Conclusion Generation

1 code implementation EMNLP (ArgMining) 2021 Juri Opitz, Philipp Heinisch, Philipp Wiesenbach, Philipp Cimiano, Anette Frank

When assessing the similarity of arguments, researchers typically use approaches that do not provide interpretable evidence or justifications for their ratings.

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.

BiQuAD: Towards QA based on deeper text understanding

no code implementations Joint Conference on Lexical and Computational Semantics 2021 Frank Grimm, Philipp Cimiano

Recent question answering and machine reading benchmarks frequently reduce the task to one of pinpointing spans within a certain text passage that answers the given question.

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.

Recent Developments for the Linguistic Linked Open Data Infrastructure

In this paper we describe the contributions made by the European H2020 project {``}Pr{\^e}t-{\`a}-LLOD{''} ({`}Ready-to-use Multilingual Linked Language Data for Knowledge Services across Sectors{'}) to the further development of the Linguistic Linked Open Data (LLOD) infrastructure.

Zero-Shot Cross-Lingual Opinion Target Extraction

no code implementations NAACL 2019 Soufian Jebbara, Philipp Cimiano

In this work, we address the lack of available annotated data for specific languages by proposing a zero-shot cross-lingual approach for the extraction of opinion target expressions.

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.

AMUSE: Multilingual Semantic Parsing for Question Answering over Linked Data

1 code implementation26 Feb 2018 Sherzod Hakimov, Soufian Jebbara, Philipp Cimiano

We present the first multilingual QALD pipeline that induces a model from training data for mapping a natural language question into logical form as probabilistic inference.

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 Sentiment Analysis Using a Two-Step Neural Network Architecture

no code implementations19 Sep 2017 Soufian Jebbara, Philipp Cimiano

We propose a neural network based system to address the task of Aspect-Based Sentiment Analysis to compete in Task 2 of the ESWC-2016 Challenge on Semantic Sentiment Analysis.

Improving Opinion-Target Extraction with Character-Level Word Embeddings

no code implementations WS 2017 Soufian Jebbara, Philipp Cimiano

In this work, we investigate whether character-level models can improve the performance for the identification of opinion target expressions.

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.

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.
