Sammendrag
The content generated on the web originates from diverse sources with the mainpurpose of serving updated information to the Internet user. Every piece of informationgenerated is valuable and must be easily traced by modern search engines.Semantic meta-data as a mechanism for providing meaning to the generated contentis the de-facto requirement for improving search accuracy and facilitating informationdiscovery on the web. This research represents an attempt for advancingthe field of semantic web in terms of providing an approach for generating semanticinformation to the substantial number of unstructured documents available onthe web. The main objective is to utilize the potential of human computation asa source for improving the performance of supervised and semi-supervised algorithmsin the respective field. Performance improvements are achieved through thegeneration of large-scale qualitative annotation data. Being a time and resourceintensive process to be carried out by expert annotators, ordinary non-expert annotatorsmust be encouraged for contribution.
Gamification as an increasingly popular approach for leveraging human computationalpower has been investigated in this research study. It represents theultimate tool for encouraging human annotators for contribution in exchange foran engaging and attractive game. The disambiguation of recognized named entitieswithin the content of unstructured web documents represents the problemelaborated in this work. Therefore, the implementation of a generic and scalablegamified named entity disambiguation framework demonstrating the capabilitiesof non-expert users in generating large-scale annotation data represents the mainqualities composing this research study. We specifically focus on benefiting fromgamification as a powerful and prominent approach for leveraging human computation.Significant and confident results acquired through experimental user studiessupport the idea that gamification can successfully leverage human computationfor collaboratively solving complex problems. This comes as a result of game designwhich is based on on empirical research, psychological theories for motivationand standard practice of implementation.
