Title: Argument Analysis for Structure Definition in User Generated Content
Abstract: In traditional print media journalists, academics and other writers perform the tasks of collating and curating information to present in a structured way to consumers. These professionals summarise the debates and add in their own claims and evidence. The consumer of this content is then free to consult this evidence and determine their own beliefs. In the Internet domain there is an overwhelming amount of information available, some is collated and curated in this manner but much is not. There are several good information sources which can provide facts and general information but it is less obvious where to find meaningful discussions and arguments that are grounded with evidence. Tools are freely available that allow users to be both producers and consumers of content and to be part of the wider internet conversation. Users add data to social networking sites, they use the add comments sections of news articles, they blog or micro blog and they contribute to articles for information collation sites such as Wikipedia. Any evaluations that occur in these discussions must be conducted by humans because any argument structure is not presented explicitly and therefore cannot be automatically analysed. If a user wishes to hear all sides of an argument (the full argument space) it can be difficult to find all the right information. The aim of this talk is to provide an overview to automatic methods and techniques for the identification and extraction of the structure of arguments from user generated content, as well as the display of this structure and the provision of help to the users in order for them to identify where they should add their own content. We will discuss current approaches for extracting arguments from user generated content and we will also provide a detailed overview of argument theory.
