Publishing of comments is a form of interaction that has become an important part of the Social Web phenomenon. Comments are enhancing online interaction, however their visualization and ranking becomes extremely difficult or even impossible for videos or other types of online articles that have millions of comments linked to them. This paper presents a method to identify the most relevant comments published for a video uploaded on the YouTube video-sharing platform, offering at the same time a detailed analysis of the features that are relevant for the most important comments linked to an article. The analysis we have performed shows that videos from different categories have different relevant attributes and there are important differences between these attributes for specific pairs of categories (e.g. Music vs. Education).

The accessibility of public websites is essential for the successful implementation of the information society. Given that the society includes people with various forms of disability (visual impairments, cognitive, hearing, etc.) they should also have equal opportunities in accessing and using the public information. This paper presents the results of a study carried on in 2015 that assess the accessibility of 150 municipal web sites. The evaluation was done with Total Validator. The accessibility issues have been compared with the results of previous studies. The results show a low level of web accessibility and instability of results in time.

The paper proposes visual analysis techniques as a solution to the scientific community concerned with developing performant algorithms for exploring and analyzing massive and multidimensional data. The actually high performance computation infrastructures such as cloud, grids, multicore, and clusters, are able more or less to cover the computation requirements for transformation, classification, and highlighting of significant data. Even so, the analytical capacity of these systems is still limited. Nevertheless the human brain has a much greater analytical and synthetic capacity. This paper presents the development and the experiments on the visual analyzing techniques in the domain of strategic games. The visual techniques of developing strategies for the tower defense games are exemplified and evaluated. The metrics for strategy evaluation and the experiments on interactive visual navigation techniques throughout the value space in order to support the convergence toward the optimum solutions are detailed. The visual analyzing techniques and the exemplified solutions could be of interest for players who wish to improve their performance and for strategic game developers as well.
