Martin Potthast - Technologies for Information Retrieval and Summarization
An argument is a text span composed of a claim that is supported by reasons. In recent years, mining arguments from text has become a hot topic in natural language processing. As the technology to identify arguments in text matures, larger and larger datasets of arguments on a wide variety of topics have been compiled. In order to facilitate their use in practical applications, such as an argument search engine, tailored approaches to the retrieval of arguments and their summarization play a key role. This talk discusses a number of basic and applied technologies for information retrieval and summarization with applications to the retrieval of arguments.
