A growing body of work has highlighted the challenges of identifying the stance a speaker holds towards a particular topic, a task that involves identifying a holistic subjective disposition. We examine stance classification on a corpus of 4873 posts across 14 topics on ConvinceMe.net, ranging from the playful to the ideological. We show that ideological debates feature a greater share of rebut...

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 ...

This paper reports research on temporal expressions. The analyzed phrases include a common temporal expression for a period of years reinforced by an adverb of time. We found that some of those phrases are age-related expressions. We analyzed samples obtained from the Internet for Spanish and French to determine appropriate annotations for marking up text and possible translations. We present t...

Every HCI artefact reproduces a specific stance towards its users. Influential within the academic sphere is the notion of a UserCentered-Design process. However, observing actual design practice renders the assumption of the centrality of users problematic. To this end, the text conducts an exploration of the relationship between discourse within the fields of HCI and architecture. A special f...

This paper introduces the GEMEP (GenevaMultimodal Emotion Portrayals) corpus, a new repository of portrayed emotional expressions. Corpora of acted portrayals tend to include portrayals of very intense emotions, which are considered to occur infrequently in daily interactions between humans or between humans and machines. Acted portrayals have therefore been challenged as unsuited for applied r...

We characterize equilibrium gaits of a small knee monoped in terms of manifest parameters by recourse to approximate closed form expressions. We first eliminate gravity during stance and choose a very special model of potential energy storage in the knee. Next, we introduce simple closed form approximations, motivated by the mean value theorem, to the elliptic integrals arising in the more gene...
