Extracting Definitions of Mathematical Expressions in Scientific Papers

Natural language definitions of mathematical expressions are essential for understanding the mathematical content of scientific papers. A textual description corresponding to a mathematical expression determines the type of symbol or function and the specific name for reference. Our objective is to create an automatic way of extracting definitions of mathematical expressions. We needed to creat...

Extracting Ontological Knowledge from Textual Descriptions

Authoring of OWL-DL ontologies is intellectually challenging and to make this process simpler, many systems accept natural language text as input. A text-based ontology authoring approach can be successful only when it is combined with an effective method for extracting ontological axioms from text. Extracting axioms from unrestricted English input is a substantially challenging task due to the...

Extracting Positive Attributions from Scientific Papers

The aim of our work is to provide support for reading (or skimming) scientific papers. In this paper we report on the task to identify concepts or terms with positive attributions in scientific papers. This task is challenging as it requires the analysis of the relationship between a concept or term and its sentiment expression. Furthermore, the context of the expression needs to be inspected. ...

Extracting and Querying Relations in Scientific Papers on Language Technology

We describe methods for extracting interesting factual relations from scientific texts in computational linguistics and language technology taken from the ACL Anthology. We use a hybrid NLP architecture with shallow preprocessing for increased robustness and domainspecific, ontology-based named entity recognition, followed by a deep HPSG parser running the English Resource Grammar (ERG). The ex...

Extracting Appraisal Expressions

Sentiment analysis seeks to characterize opinionated or evaluative aspects of natural language text. We suggest here that appraisal expression extraction should be viewed as a fundamental task in sentiment analysis. An appraisal expression is a textual unit expressing an evaluative stance towards some target. The task is to find and characterize the evaluative attributes of such elements. This ...
