“…An important premise of our approach is that comments actually describe the commented item to some extent, which is what we have investigated earlier [5]. In short, we found that comments on text are indeed descriptive: 10 comments are sufficient to reach a considerable similarity between a text and its comments, which Copyright is held by the author/owner(s).…”

This paper investigates whether Web comments can be exploited for cross-media retrieval. Comparing Web items such as texts, images, videos, music, products, or personal profiles can be done at various levels of detail; our focus is on topic similarity. We propose to compare user-supplied comments on Web items in lieu of the commented items themselves. If this approach is feasible, the task of extracting and mapping features between arbitrary pairs of item types can be circumvented, and well-known text retrieval models can be applied instead-given that comments are available. We report on results of a preliminary, but nonetheless large-scale experiment which shows that, if comments on textual items are compared with comments on video items, topically similar pairs achieve a sufficiently high cross-media similarity.

“…Al respecto, señala que diez comentarios son sufi cientes para determinar una gran similitud entre los textos y sus comentarios. De esta manera, los comentarios podrían ser utilizados en lugar del objeto que comentan en tareas de recuperación de textos (Potthast, 2009).…”

Interacción en cibermedios: la reacción de los lectores ante noticias y columnas de opinión 1 Interaction in online media: Readers' reaction to news and opinion RESUMEN -Emitir comentarios en los sitios web de la prensa digital es una práctica nueva desarrollada gracias al aumento de la interactividad en Internet. La mayoría de los medios periodísticos electrónicos han implementado blogs en sus sitios web, con el objetivo de recibir retroalimentación de sus lectores. El surgimiento de esta práctica brinda la posibilidad concreta de analizar aspectos clave de la relación de los medios de comunicación con sus audiencias, a su vez, conocer algunas características de la extensión del espacio público al ambiente virtual. Se constituyó un corpus de 480 comentarios asociados a 24 artículos de dos géneros distintos, a saber: columnas de opinión y noticias, de tres medios electrónicos chilenos. Se analizó el comportamiento de los lectores ante el artículo principal y los otros comentarios. Se identifi có a qué reacciona específi camente el comentario, si el posicionamiento es a favor o en contra respecto del objeto de la reacción. Los hallazgos revelan que los comentaristas reaccionan más en torno a otros comentarios y al tema en general que a los contenidos presentados por los medios. Asimismo, podemos afi rmar que la forma de reaccionar se ve afectada por el género periodístico del artículo principal, como también por algunas características de los diarios estudiados.Palabras clave: blogs, ciberperiodismo, esfera pública, comunicación interactiva, comentario en línea. ABSTRACT -The comments in digital journalism websites are a new practice developed thanks to the increase in internet interactivity. Most of the electronic journalism media have implemented blogs on their websites in order to receive feedback from their readers. The emergence of this practice brings the concrete possibility of analyzing key aspects of the relation between the communication media and their audience and of recognizing some characteristics of the extension of public space to a virtual milieu. A corpus of 480 commentaries linked to 24 articles of two different genres was constituted, namely opinion columns and news, in three Chilean electronic media. The readers' response to the main article and the other comments were analyzed, trying to identify the specifi c type of response to comments and whether the positioning is in favor of or against the object of response. The fi ndings show that the commentators respond more to other comments and the general topic than to the contents presented by the media. It can also be claimed that the form of response is affected by the journalistic genre of the main article, as well as by some particularities of the newspapers studied.

“…Comments and messaging structure in blogs and shared social spaces have been used to understand dialogue based conversational behavior among individuals (Schuth et al, 2007) as well as in the context of summarization of social activity on the online platform (Lu et al, 2009;Hu et al, 2007) or to understand the descriptive nature of web comments (Potthast, 2009). Some prior work have also deployed conversational nature of comments to understand social network structure as well as in statistical analysis of networks (Gómez et al, 2008).…”

The outcomes of this research are manifold. I present the contributions in three parts, corresponding to the three key organizing ideas. First, it is observed that user context is key to characterizing communication between a pair of individuals. However interestingly, the probability of future communication seems to be i more sensitive to the context compared to the delay, which appears to be rather habitual. Further, it is observed that diffusion of social actions in a network can be indicative of future information cascades; that might be attributed to social influence or homophily depending on the nature of the social action. Second, it is also observed that different modes of social engagement lead to evolution of groups that have considerable predictive capability in characterizing external-world temporal occurrences, such as stock market dynamics as well as collective political sentiments. Sihem Amer-Yahia and Dr. Doree Duncan Seligmann during these three internships.The research I accomplished during these internships, enabled with the wonderful computing infrastructure and the rich availability of data, will remain very central to my academic accomplishment during the graduate school years. Additionally, encouraging discussions, fruitful guidance and generous help from Winter, Jake, Cong, Ronny, Ajita and Michael also helped me gather enthusiasm, have fun and remain on top of exciting research problems.
