Towards understanding the implications of social role manipulation in online tasks

This paper provides an initial discussion of the ethical issues arising when people are asked to assume a role and, from the perspective of that role, asked to carry out an online task. We identify the following considerations: (a) People’s responses when playing a role can reveal personal information about themselves. (b) When people are asked to review the contributions of others who have a particular role, their behavior might indicate how they feel about these roles in their own life. (c) It is difficult to explain to people what they reveal about themselves when reporting their perception of the views of others. (d) People’s own view might change when they play a certain role for an extended period of time

Deliverable D6.3 User Trial Results

User trials were prepared and conducted in the first quarter of 2014 in order to assess the appropriateness of the innovative functionalities of the second screen demonstrator developed in Y2 of the LinkedTV project. A sample installation of LinkedTV was set up at three different locations: at Rundfunk Berlin Brandenburg (RBB), Sound & Vision (S&V), and at the University of St. Gallen (USG). The LinkedTV installation included a TV showing sample content (“main screen”) and an tablet (“second screen”) showing chapters of the program as well as semi-automaticaly acquired additional information about persons, topics and places depicted in the program on the main screen. In total 24 participants took part in the trial at all three locations (9 at RBB, 5 at S&V and 10 at USG). To assess the appropriateness of the LinkedTV features, the trial participants were provided with a “hands-on” opportunity to use the LinkedTV Application and were observed while using the installation. The participants also filled in a questionnaire at the end of the session

Is it a bird or is it a crow? The influence of presented tags on image tagging by non-expert users

Cultural heritage institutes often make use of tags to facilitate searching their collections. While professionals associated with these institutes are able to add high quality descriptions to objects in the collections, both their time and their areas of expertise are limited. As a result, online tagging by non-professional users is more frequently becoming deployed to increase the number of tags. When these users are asked to tag objects in the collection, they can be confronted with tags submitted by other users. These tags may be of varying quality and present in differing numbers, both of which may influence users' tagging behavior. We report on a study on the impact of presenting different types of tags on the quality and quantity of tags added by users. We conclude that there is no difference in the quality and quantity of added tags in all experimental conditions, with the exception of the condition in which incorrect tags were presented. In this condition, the quality of the tags added by users decreased. We discuss the implications of these findings on the design of tagging interfaces

Second Screen Interactions for Automatically Web-Enriched Broadcast Video

Including hypermedia in broadcast video combines content formatted for a lean-forward medium (the Web) with a lean-back one (TV) to form a hybrid medium. We identify four challenges for interacting with and experiencing this new medium. We discuss the role a second screen may play in addressing these challenges

Deliverable D3.2 Specification of Presentation Interfaces for the Three Scenarios

This deliverable presents a state-of-art and requirements analysis report for hypervideo authored as part of the WP1 of the LinkedTV project. Initially, we present some use-case (viewers) scenarios in the LinkedTV project and through the analysis of the distinctive needs and demands of each scenario we point out the technical requirements from a user-side perspective. Subsequently we study methods for the automatic and semi-automatic decomposition of the audiovisual content in order to effectively support the annotation process. Considering that the multimedia content comprises of different types of information, i.e., visual, textual and audio, we report various methods for the analysis of these three different streams. Finally we present various annotation tools which could integrate the developed analysis results so as to effectively support users (video producers) in the semi-automatic linking of hypervideo content, and based on them we report on the initial progress in building the LinkedTV annotation tool. For each one of the different classes of techniques being discussed in the deliverable we present the evaluation results from the application of one such method of the literature to a dataset well-suited to the needs of the LinkedTV project, and we indicate the future technical requirements that should be addressed in order to achieve higher levels of performance (e.g., in terms of accuracy and time-efficiency), as necessary

Manipulating social roles in a tagging environment

Social roles structure daily life because people adjust their behavior according to the role that they have in a specific situation. Online social roles are not necessarily the same as those in daily life and, because they are not so strictly assigned, the question arises whether they can be manipulated. We conducted a structured experiment to investigate whether the manipulation of online social roles can affect user behavior in a tagging task

Deliverable D3.3 LinkedTV user interfaces sketch

We present a selection user interfaces for the LinkedTV system designed for two scenario partners: RBB and Beeld en Geluid. In the user interfaces we take into account the requests of the scenario partners and the content of the show that are used in the scenarios. The different interfaces are presented by mock-ups that were made by an online mock-up tool and they are accompanied by a discussion. The mock-ups that are presented in this deliverable will be used in user studies that are planned in the following year of the LinkedTV project

Crowd vs Experts: Nichesourcing for Knowledge Intensive Tasks in Cultural Heritage

The results of our exploratory study provide new insights to crowdsourcing knowledge intensive tasks. We designed and performed an annotation task on a print collection of the Rijksmuseum Amsterdam, involving experts and crowd workers in the domain-specific description of depicted flowers. We created a testbed to collect annotations from flower experts and crowd workers and analyzed these in regard to user agreement. The findings show promising results, demonstrating how, for given categories, nichesourcing can provide useful annotations by connecting crowdsourcing to domain expertise

Antiques Interactive

We demonstrate the potential of automatically linking content from television broadcasts in the context of enriching the experience of users watching the broadcast. The demo focusses on (1) providing smooth user interface that allows users to look up web content and other audiovisual material that is directly related to the television content and (2) providing means for social interaction
