Unsupervised Detection of Argumentative Units though Topic Modeling Techniques

چکیده
In this paper we present a new unsupervised approach, “Attraction to Topics” – A2T , for the detection of argumentative units, a sub-task of argument mining. Motivated by the importance of topic identification in manual annotation, we examine whether topic modeling can be used for performing unsupervised detection of argumentative sentences, and to what extend topic modeling can be used to classify sentences as claims and premises. Preliminary evaluation results suggest that topic information can be successfully used for the detection of argumentative sentences, at least for corpora used in the evaluation. Our approach has been evaluated on two English corpora, the first of which contains 90 persuasive essays, while the second is a collection of 340 documents from user generated content.

Unsupervised corpus-wide claim detection
Automatic claim detection is a fundamental argument mining task that aims to automatically mine claims regarding a topic of consideration. Previous works on mining argumentative content have assumed that a set of relevant documents is given in advance. Here, we present a first corpus– wide claim detection framework, that can be directly applied to massive corpora. Using simple and intuitive emp...
متن کاملThe Effect of Cognitive Factors of Rhetorically Different Listening Tasks on L2 Listening Quality of Iranian Advanced EFL Learners
This study examined the effect of two different authentic topic-familiar rhetorical L2 listening tasks (expository and argumentative) differing in reasoning demand on the listening comprehension scores of a number of Iranian EFL advanced learners. Sixty homogeneous advanced learners were recruited based on their performance on an English Language Proficiency test (Fowler & Coe, 1976). Then they...
متن کاملTraffic Scene Analysis using Hierarchical Sparse Topical Coding
Analyzing motion patterns in traffic videos can be exploited directly to generate high-level descriptions of the video contents. Such descriptions may further be employed in different traffic applications such as traffic phase detection and abnormal event detection. One of the most recent and successful unsupervised methods for complex traffic scene analysis is based on topic models. In this pa...
متن کاملSpoken Document Retrieval Leveraging Unsupervised and Supervised Topic Modeling Techniques
This paper describes the application of two attractive categories of topic modeling techniques to the problem of spoken document retrieval (SDR), viz. document topic model (DTM) and word topic model (WTM). Apart from using the conventional unsupervised training strategy, we explore a supervised training strategy for estimating these topic models, imagining a scenario that user query logs along ...
متن کاملUnsupervised learning of rhetorical structure with un-topic models
In this paper we investigate whether unsupervised models can be used to induce conventional aspects of rhetorical language in scientific writing. We rely on the intuition that the rhetorical language used in a document is general in nature and independent of the document’s topic. We describe a Bayesian latent-variable model that implements this intuition. In two empirical evaluations based on t...
