Opsins are a large group of proteins with seven transmembrane segments (TMSs) that are found in all domains of life. There are two types of opsins that are sometimes considered nonhomologous: type I is known from prokaryotes and some eukaryotes, while type II is known only from Eumetazoan animals. Type II opsins are members of the family of G-protein(More)
—We propose a framework for discovery of collaborative community structure in Wiki-based knowledge repositories based on raw-content generation analysis. We leverage topic modelling in order to capture agreement and opposition of contributors and analyze these multi-modal relations to map communities in the contributor base. The key(More)
Collaboration capabilities are becoming pervasive in online applications. Internet users have access to tools for collective image annotation and editing (flickr, Picasa, Facebook), text content generation (Wikipedia, Google Docs) and even social coding (github). Arguably, social media and social knowledge systems are among the highest impact applications(More)
Spatial networks, in which nodes and edges are embedded in space, play a vital role in the study of complex systems. For example, many social networks attach geo-location information to each user, allowing the study of not only topological interactions between users, but spatial interactions as well. The defining property of spatial networks is that edge(More)
Accurately estimating the current positions of moving objects is a challenging task due to the various forms of data uncertainty (e.g. limited sensor precision, periodic updates from continuously moving objects). However, in many cases, groups of objects tend to exhibit similarities in their movement behavior. For example, vehicles in a convoy or animals in(More)
Recent advances in affordable positioning hardware and software have made the availability of location data ubiquitous. Personal devices such as tablet PCs, smart phones and even sport watches are all able to collect and store a user’s location over time, providing an ever-growing supply of spatiotemporal data. Managing this plethora of data is a relatively(More)
