Word Affect Intensities

Words often convey affect -- emotions, feelings, and attitudes. Lexicons of word-affect association have applications in automatic emotion analysis and natural language generation. However, existing lexicons indicate only coarse categories of affect association. Here, for the first time, we create an affect intensity lexicon with real-valued scores of association. We use a technique called best-worst scaling that improves annotation consistency and obtains reliable fine-grained scores. The lexicon includes terms common from both general English and terms specific to social media communications. It has close to 6,000 entries for four basic emotions. We will be adding entries for other affect dimensions shortly

Pengaruh Word Affect Intensities Terhadap Deteksi Ulasan Palsu

Transaksi jual beli elektronik melalui internet terus berkembang dan menjadi populer, begitu pula dengan jumlah ulasan dari pelanggan yang meningkat pesat. Dengan banyaknya pemberi ulasan, terdapat kemungkinan seseorang menulis ulasan palsu yang disebut fake review untuk mempromosikan produk atau menjatuhkan produk kompetitor. Sangat penting untuk dapat mendeteksi ulasan palsu sehingga ulasan yang digunakan pelanggan sebagai pertimbangan untuk memilih produk atau jasa merupakan ulasan yang andal. Studi sebelumnya hanya menggunakan fitur sentimen yang terbatas pada objektivitas dan polaritas untuk melakukan deteksi ulasan palsu. Sedangkan studi yang lebih baru menunjukan adanya leksikon kosa kata berbasis emosi yang diberi nama word affect intensities yang terbukti mampu mengukur sentimen dengan lebih baik pada kalimat. Penelitian ini bermaksud untuk mengetahui apakah word affect intensities dapat menjadi faktor yang mempengaruhi hasil deteksi ulasan palsu. Penelitian dilakukan dengan memunculkan dua fitur baru berlandaskan word affect intensities berupa fitur kelompok emosi positif dan fitur kelompok emosi negatif. Fitur tersebut kemudian dikombinasikan dengan fitur pada penelitian sebelumnya dan dievaluasi menggunakan beberapa algoritme klasifikasi. Hasil penelitian menunjukan word affect intensities dapat menjadi faktor yang mempengaruh peningkatan akurasi deteksi ulasan palsu sebesar 2.1%. Abstract Electronic buying and selling transactions over the internet continue to grow and become popular, as well as the number of reviews from customers that is increasing rapidly. With so many reviewers, it is possible that someone wrote a fake review to promote a product or demote a competitor’s product. It is very important to be able to detect fake review so that the reviews customers use as a consideration for choosing a product or service are reliable reviews. Previous studies only used sentiment features that were limited to objectivity and polarity to detect fake review. Meanwhile, a more recent study shows that there is an emotion-based vocabulary lexicon called word affect intensities which are proven to be able to better measure sentiment in sentences. This study intends to determine whether word affect intensities can be a factor that affects the results of fake review detection. The research was conducted by bringing up two new features based on the word affect intensities in the form of positive emotion group features and negative emotion group features. These features are then combined with features in previous studies and evaluated using several classification algorithms. The results showed that word affect intensities can be a factor that affects the increased accuracy of fake review detection by 2.1%

Responses to intensity-shifted auditory feedback during running speech

PURPOSE: Responses to intensity perturbation during running speech were measured to understand whether prosodic features are controlled in an independent or integrated manner. METHOD: Nineteen English-speaking healthy adults (age range = 21-41 years) produced 480 sentences in which emphatic stress was placed on either the 1st or 2nd word. One participant group received an upward intensity perturbation during stressed word production, and the other group received a downward intensity perturbation. Compensations for perturbation were evaluated by comparing differences in participants' stressed and unstressed peak fundamental frequency (F0), peak intensity, and word duration during perturbed versus baseline trials. RESULTS: Significant increases in stressed-unstressed peak intensities were observed during the ramp and perturbation phases of the experiment in the downward group only. Compensations for F0 and duration did not reach significance for either group. CONCLUSIONS: Consistent with previous work, speakers appear sensitive to auditory perturbations that affect a desired linguistic goal. In contrast to previous work on F0 perturbation that supported an integrated-channel model of prosodic control, the current work only found evidence for intensity-specific compensation. This discrepancy may suggest different F0 and intensity control mechanisms, threshold-dependent prosodic modulation, or a combined control scheme.R01 DC002852 - NIDCD NIH HHS; R03 DC011159 - NIDCD NIH HH

Still seeking the audience

The changing capacities to connect generated through contemporary media have implications for an understanding of the idea of ‘audience’. This paper begins a new search for an understanding of the contemporary audience and seeks this through an engagement with a few key ideas that sign-post a reconsideration of my own understanding of what an audience might become. Massumi’s idea of intensity, Bennett’s use of assemblage and the focus on event to emphasize the dynamic nature of an audience help to guide my trajectory. Finally I attempt to apply these ideas to a personal experience of becoming an audience to see how useful they might be as I continue to question my own habituated conceptualisations

Sprint-based exercise and cognitive function in adolescents.

Moderate intensity exercise has been shown to enhance cognition in an adolescent population, yet the effect of high-intensity sprint-based exercise remains unknown and was therefore examined in the present study. Following ethical approval and familiarisation, 44 adolescents (12.6 ± 0.6 y) completed an exercise (E) and resting (R) trial in a counter-balanced, randomised crossover design. The exercise trial comprised of 10 × 10 s running sprints, interspersed by 50 s active recovery (walking). A battery of cognitive function tests (Stroop, Digit Symbol Substitution (DSST) and Corsi blocks tests) were completed 30 min pre-exercise, immediately post-exercise and 45 min post-exercise. Data were analysed using mixed effect models with repeated measures. Response times on the simple level of the Stroop test were significantly quicker 45 min following sprint-based exercise (R: 818 ± 33 ms, E: 772 ± 26 ms; p = 0.027) and response times on the complex level of the Stroop test were quicker immediately following the sprint-based exercise (R: 1095 ± 36 ms, E: 1043 ± 37 ms; p = 0.038), while accuracy was maintained. Sprint-based exercise had no immediate or delayed effects on the number of items recalled on the Corsi blocks test (p = 0.289) or substitutions made during the DSST (p = 0.689). The effect of high intensity sprint-based exercise on adolescents' cognitive function was dependant on the component of cognitive function examined. Executive function was enhanced following exercise, demonstrated by improved response times on the Stroop test, whilst visuo-spatial memory and general psycho-motor speed were unaffected. These data support the inclusion of high-intensity sprint-based exercise for adolescents during the school day to enhance cognition

Toward an Affective Problematics: A Deleuze-Guattarian Reading of Morality and Friendship in Toni Morrison’s Sula

It might sound rather convincing to assume that we owe the pleasure of reading the novel form to our elemental repository of physical perception, to our feelings. This would be true only if mere feelings could add up to something more than just emotions, to some deep understanding of the human. After all, a moment of epiphany, where we begin to realize things that dramatically disturb our normal state of mind, is not just emotional, nor indeed a simple moment. Despite its root in the corporeal, a mo(ve)ment of affective realization reaches beyond the realm of the human and opens up the plane of virtual potentials. In this work, we intend to map out the points and relations of affective singularity that pervade the narrative of Toni Morrison’s Sula (1973). Also, we will discuss how these mo(ve)ments of sensation give form to Sula’s and Nel’s experiences and contribute to an affective transformation in morality and friendship

Circle Detection Using the Image Ray Transform

Physical analogies are an exciting paradigm for creating techniques for image feature extraction. A transform using an analogy to light rays has been developed for the detection of circular and tubular features. It uses a 2D ray tracing algorithm to follow rays through an image, interacting at a low level, to emphasise higher level features. It has been empirically tested as a pre-processor to aid circle detection with the Hough Transform and has been shown to provide a clear improvement over standard techniques. The transform was also used on natural images and we show its ability to highlight circles even in complex scenes. We also show the flexibility available to the technique through adjustment of parameters
