RecSys'12 - Proceedings of the 6th ACM Conference on Recommender Systems English 2012 This paper presents an interactive hybrid recommendation system that generates item predictions from multiple social and semantic web resources, such as Wikipedia, Facebook, and Twitter. The system employs hybrid techniques from traditional recommender system literature, in addition to a novel interactive interface which serves to explain the recommendation process and elicit preferences from the end user. We present an evaluation that compares different interactive and non-interactive hybrid strategies for computing recommendations across diverse social and semantic web APIs. Results of the study indicate that explanation and interaction with a visual representation of the hybrid system increase user satisfaction and relevance of predicted content.

WiGipedia: A tool for improving structured data in Wikipedia Proceedings - 5th IEEE International Conference on Semantic Computing, ICSC 2011 English 2011 Wikipedia is emerging as the dominant global knowledge repository. Recently, large numbers of users have collaborated to produce more structured information in the so called "infoboxes". However, editing this data requires even more care than editing standard wikitext, as one must follow arcane template syntax. This paper describes WiGipedia, a novel tool which provides an alternative to the traditional approach, by supporting editing of structured wiki data through two intuitive and interactive interfaces, facilitating user input on both tabular and graph-based representations of structured data. The tool allows users to identify and correct inconsistencies that are otherwise hidden across multiple articles. Furthermore, a novel recommendation algorithm is applied to assist users in their contribution to the wiki. The paper discusses design, implementation details, and results of a usability study in which the system compares significantly well against the traditional approach to editing Wikipedia infoboxes. 0 0
