Text of the page (random words):
thor poem with the finite turker theorem and market places such as mechanical turk it might be possible to outsource creative work such as poem writing to a large set of workers without much penalty in terms of beauty or enjoyability algorithms such as the one above can constraint and influence the resulting poems giving greater control about the outcome of creative processes which sounds like an oxymoron because hits were requested multiple times there were several rejects that did not make it into the final poem but which show some of the difficulties as well as the creative potential of programmed poems including for i return and refresh and come back for more info my pimp i m a dolores labs penny whore conclusion it has been suggested that the primary use of mechanical turk is the execution of simple easily replacable and often spam related work this little experiment suggests that mechanical turk can serve richer purposes by tapping into the creative energy of an underestimated underutilized but also currently underpaid work force comments 5 comments tags acrostic amazon creativity crowd programming crowdsourcing human computation mechanical turk poem programming poems poetry programming crowds categories research a game with a purpose based on twitter 11 10 2010 i am happy to announce that my research group at tu graz has launched bulltweetbingo a game with a purpose based on twitter today the game is already live and available at http bingo tugraz at for an introduction to the idea of buzzword bingo please see the following ibm commercial youtube video ibm innovation buzzword bingo youtube rather than playing buzzword bingo while listening to a talk the idea of bulltweetbingo is to play buzzword bingo with the people you follow on twitter all people you follow on twitter automatically participate in the game by tweeting a bulltweetbingo game terminates i e hits bingo if the people you follow on twitter use a particular combination of the defined buzzwords in their tweets we intend to use the data provided by each game in our research on analzying the semantics of short messages on systems such as twitter or facebook each game provides information about the relevance and topics of tweets for a particular person as well as some information on the topics of tweets that a person expects to receive in the future i m copy n pasting some more information about the game that we have made available on the game website about the project bulltweetbingo playing a game of bingo with people you follow on twitter a team of researchers from graz university of technology austria has developed one of the first games with a purpose that is exclusively based on twitter the goal of this project is to annotate and to better understand the short messages posted to so called social awareness streams such as twitter or facebook using this data the researchers aim to improve the ability of computers to effectively organize and make sense out of the sea of short messages available today dr markus strohmaier assistant professor at the knowledge management institute at graz university of technology austria explains while social awareness streams such as twitter or facebook have experienced significant popularity over the last few years we know little about how to best understand search and organize the information that is contained in them to tackle this problem the researchers have developed a game of buzzword bingo that users can play with people they follow on twitter with each game users play on our website we will collect data that helps us develop more effective algorithms for better understanding this new kind of data dr markus strohmaier says and in addition to that we simply hope users would enjoy playing a game of bingo on twitter each game is unique and exciting in a sense that users generally don t know what tweets people will publish during the course of a bingo game the researchers have launched the site bulltweetbingo and ask users to sign up and to play a game of bingo with the people they follow on twitter twitter users can sign up at http bingo tugraz at the game was implemented

the usefulness of tag clouds at the ieee socialcom 2010 conference in minneapolis minnesota usa in this paper download pdf we investigated if and to what extent tag clouds a popular mechanism for interacting with social media are useful for navigation an exemplary tag cloud from flickr com while tag clouds can potentially serve different purposes there seems to be an implicit assumption among engineers of social tagging systems that tag clouds are specifically useful to support navigation this is evident in the large scale adoption of tag clouds for interlinking resources in numerous systems such as flickr delicious and bibsonomy however this navigability assumption has hardly been critically reflected with some notable exceptions for example 1 and has largely remained untested in the past in this paper we demonstrate that the prevalent approach to tag cloud based navigation in social tagging systems is highly problematic with regard to network theoretic measures of navigability in a series of experiments we will show that the navigability assumption only holds in very specific settings and for the most common scenarios we can assert that it is wrong while recent research has studied navigation in social tagging systems from user interface 2 3 4 and network theoretic 5 perspectives the unique focus of this paper is the intersection of these issues this paper provides answers to questions such as how do user interface constraints of tag clouds affect the navigability of tagging systems and how efficient is navigation via tag clouds from a network theoretic perspective particularly we first 1 investigate the intrinsic navigability of tagging datasets without considering user interface effects and then 2 take pragmatic user interface constraints into account we 3 will demonstrate that for many social tagging systems the so called navigability assumption does not hold and we will finally 4 use our findings to illuminate a path towards improving the navigability of tag clouds here s the abstract abstract it is a widely held belief among designers of social tagging systems that tag clouds represent a useful tool for navigation this is evident in for example the increasing number of tagging systems offering tag clouds for navigational purposes which hints towards an implicit assumption that tag clouds support efficient navigation in this paper we examine and test this assumption from a network theoretic perspective and show that in many cases it does not hold we first model navigation in tagging systems as a bipartite graph of tags and resources and then simulate the navigation process in such a graph we use network theoretic properties to analyse the navigability of three tagging datasets with regard to different user interface restrictions imposed by tag clouds our results confirm that tag resource networks have efficient navigation properties in theory but they also show that popular user interface decisions such as pagination combined with reverse chronological listing of resources significantly impair the potential of tag clouds as a useful tool for navigation based on our findings we identify a number of avenues for further research and the design of novel tag cloud construction algorithms our work is relevant for researchers interested in navigability of emergent hypertext structures and for engineers seeking to improve the navigability of social tagging systems the results presented in this paper make a theoretical and an empirical argument against existing approaches to tag cloud construction our work thereby both confirms and refutes the assumption that current tag cloud incarnations are a useful tool for navigating social tagging systems while we confirm that tag resource networks have efficient navigational properties in theory we show that popular user interface decisions such as pagination combined with reverse chronological listing of resources significantly impair navigability our experimental results demonstrate that popular approaches to using tag clouds for navigational purposes suffer from significant problems we conclude that in order to make full use of the potential of tag clouds for navigating social tagging systems new and more sophisticated ways of thinking about designing tag cloud algorithms are needed here s the full reference for the paper

tweetonomies 17 04 2010 towards a taxonomy of meta desserts by several_bees flickr for centuries taxonomies have been a tool for mankind to bring structure to the world taxonomies wikipedia the practice and science of classification were developed in different fields of science including but not limited to biology e g taxonomies of animals or library sciences e g taxonomies of literature regardless of the particular domain of application in most cases those taxonomies were developed by a selected few e g librarians and were used by many with the emergence of personal computers and file directories the task of taxonomy development was brought to the masses suddenly everyone i e every computer user was in charge of developing maintaining and transforming personal taxonomical structures in order to organize and re find resources while this development has led to a vast increase of personal taxonomies it was only since del icio us has popularized tagging as a new form of resource organization that users personal taxonomies were exposed publicly this has made it possible to aggregate a large number of personal taxonomies into collective taxonomic structures the result of such aggregation has since then been refered to as folksonomies i e an emergent structure collectively produced by a large number of users in a bottom up manner in social awareness streams pdf such as twitter of facebook users typically do not aim to classify or organize resources but they engage in casual chatter and dialogue ocassionally using syntax to coordinate communication such as hashtags or replies taxonomic structures can be assumed to play a subordinate role for users of social awareness streams in a recent paper to be presented at the semsearch workshop at www2010 1 however we show that there exist latent conceptual structures similar to taxonomies or folksonomies in social awareness streams and that we can acquire these structures through simple aggregation mechanisms abstract although one might argue that little wisdom can be conveyed in messages of 140 characters or less this paper sets out to explore whether the aggregation of messages in social awareness streams such as twitter conveys meaningful information about a given domain as a research community we know little about the structural and semantic properties of such streams and how they can be analyzed characterized and used this paper introduces a network theoretic model of social awareness streams a so called tweetonomy together with a set of stream based measures that allow researchers to systematically define and compare different stream aggregations we apply the model and measures to a dataset acquired from twitter to study emerging semantics in selected streams the network theoretic model and the corresponding measures introduced in this paper are relevant for researchers interested in information retrieval and ontology learning from social awareness streams our empirical findings demonstrate that different social awareness stream aggregations exhibit interesting differences making them amenable for different applications 1 in the paper we introduce the notion of tweetonomies and a corresponding tri partite model of social awareness streams that extends the existing model of folksonomies by accomodating user generated syntax such as slashtags and other emerging syntax and thereby integrating the communicative nature of such streams in the figure below we have applied the network theoretic model of tweetonomies to acquire a semantic network of hashtags that could be used for a range of different purposes such as for navigating social awareness streams or for recommendation problems a tweetonomy of hashtags aquired from twitter with the help of jan poeschko click for full image 2 6 mb our work shows that tweetonomies are a far more complex structure than for example taxonomies or folksonomies one reason for that observation lies in the dynamic and user generated nature of its syntax but also in the fact that tweetonomies accomodate a much richer language than the language used in social tagging systems tweets vs tags the results of our work suggest that tweetonomies are a novel and promising concept different from taxonomies and folksonomies where people engage in conscious acts of classification whether tweetonomies have the potential to bring order and structure to social awareness streams similar to the way folksonomies brought order to social tagging systems remains a question to be answer...
