Sederberg Associate Dean, College of Physical and Mathematical Sciences ABSTRACT A MICROFORMATTED REGISTRY ALTERNATIVE Thomas R. Warne Computer Science Department Master of Science To effectively use Web services, providers and consumers need to be connected by a registry. Several registry solutions exist today, including UDDI and WSIL. Also, many organizations simply use Web pages to list available Web services and their descriptions. This research describes a microformat for representing Web service description documents. These microformatted documents can be converted back to the original format for use by machines. They can also contain additional information, making them more useful to people. A registry, allowing indexing and searching of microformatted service descriptions, is also described. The benefits of this solution include: using existing standards; allowing customization of presentation for people; allowing existing search tools to find descriptions; and providing for future, context-based searching to make locating Web services even easier. ACKNOWLEDGMENTS I am grateful for the wonderful support of my wife, Emily, through this entire degree process. I also wish to thank Dr. Windley for his encouragements and ideas that helped to shape this thesis.

  • A Method to Analyze Multiple Social Identities in Twitter Bios
    A Method to Analyze Multiple Social Identities in Twitter Bios ARJUNIL PATHAK, University at Buffalo, USA NAVID MADANI, University at Buffalo, USA KENNETH JOSEPH, University at Buffalo, USA Twitter users signal social identity in their profile descriptions, or bios, in a number of important but complex ways that are not well-captured by existing characterizations of how identity is expressed in language. Better ways of defining and measuring these expressions may therefore be useful both in understanding howsocial identity is expressed in text, and how the self is presented on Twitter. To this end, the present work makes three contributions. First, using qualitative methods, we identify and define the concept of a personal identifier, which is more representative of the ways in which identity is signaled in Twitter bios. Second, we propose a method to extract all personal identifiers expressed in a given bio. Finally, we present a series of validation analyses that explore the strengths and limitations of our proposed method. Our work opens up exciting new opportunities at the intersection between the social psychological study of social identity and the study of how we compose the self through markers of identity on Twitter and in social media more generally.

Ph.D., Department of Computer Science and Engineering, Wright State Uni- versity, 2018. A Framework to Understand Emoji Meaning: Similarity and Sense Disambiguation of Emoji using EmojiNet. Pictographs, commonly referred to as `emoji', have become a popular way to enhance electronic communications. They are an important component of the language used in social media. With their introduction in the late 1990's, emoji have been widely used to enhance the sentiment, emotion, and sarcasm expressed in social media messages. They are equally popular across many social media sites including Facebook, Instagram, and Twitter. In 2015, Instagram reported that nearly half of the photo comments posted on Instagram contain emoji, and in the same year, Twitter reported that the `face with tears of joy' emoji has been tweeted 6.6 billion times.

    Enriching Unstructured Media Content About Events to Enable Semi-Automated Summaries, Compilations, and Improved Search by Leveraging Social Networks Thomas Steiner Departament de Llenguatges i Sistemes Informàtics Universitat Politècnica de Catalunya A thesis submitted for the degree of Philosophiæ Doctor (PhD) February 2014 1st Advisor: Joaquim Gabarró Vallés Universitat Politècnica de Catalunya, Barcelona, Spain 2nd Advisor: Michael Hausenblas Digital Enterprise Research Institute, Galway, Ireland MapR Technologies, San Jose, CA, USA ii Abstract (i) Mobile devices and social networks are omnipresent Mobile devices such as smartphones, tablets, or digital cameras together with social networks enable people to create, share, and consume enormous amounts of media items like videos or photos both on the road or at home. Such mobile devices—by pure definition—accompany their owners almost wherever they may go. In consequence, mobile devices are omnipresent at all sorts of events to capture noteworthy moments. Exemplary events can be keynote speeches at conferences, music concerts in stadiums, or even natural catastrophes like earthquakes that affect whole areas or countries. At such events—given a stable network connection—part of the event-related media items are published on social networks both as the event happens or afterwards, once a stable network connection has been established again. (ii) Finding representative media items for an event is hard Common media item search operations, for example, searching for the of- ficial video clip for a certain hit record on an online video platform can in the simplest case be achieved based on potentially shallow human-generated metadata or based on more profound content analysis techniques like optical character recognition, automatic speech recognition, or acoustic fingerprint- ing.

Step into my office, grab a coffee/glass of wine (time dependent) and be prepared to start looking at life through an entirely different lens. I'm Dani and thank you for following The Clique. So glad to have you in my circle of mind blowing women who are ready to design a business that stands out from the crowds and a lifestyle that they are utterly obsessed with. In The Clique, we are all about doing what we love and doing lots of it. We aren't prepared to settle and we want to live entirely on our own terms. That's exactly what I want for you too. I created The Clique after launching my own successful business online as a social media strategist, a business that allowed me to quit a career that didn't fulfil me, gave me the freedom to work when and from where I chose and earn more than what I ever imagined I ever would. I now help other women achieve exactly the same. Although social media strategy is still a huge part of what I do, my biggest passion now lies in empowering other women with the mindset and strategies they need in order to become their own boss, realise their fullest potential and guiding them through the process of designing a brand that sells.

  • Using Microformats and Rdfa As Embeddable Data Formats
    CHAPTER 18 Using Microformats and RDFa As Embeddable Data Formats The central problem that we will study in this chapter is how to embed information in web pages in a way that is easy to understand by both humans and computer programs. The solution that we will consider in depth is microformats, little chunks of structured data that are seamlessly embedded in web pages. (X)HTML is designed primarily to produce a human user interface (via a web browser). However, by carefully following certain conventions (ones that constitute microformats), you can produce (X)HTML out of which data can be unambiguously extracted. The consequence is that it is relatively easy to write computer programs to parse microformats so that the data can be reused in other contexts—giving rise to plenty of mashup possibilities. Moreover, having data embedded right in the context of a user interface is helpful. A user can decide what to do with this data (how to “operate” on a given piece of data) while in the context of normal browsing. Now, the previous paragraph is a bit abstract. What I will do in this chapter is walk you through some concrete examples describing microformats in general. We will use Operator, a Firefox extension, to help parse and view microformats and to create scripts that enable users to take specific actions in response to microformats. Specifically, we will do the following: * Study specific examples of microformats * Look at how to use the Firefox add-on Operator to jump-start your study of microformats * Look at programmatic approaches to consuming and creating microformats * Compare microformats to leading alternatives such as RDFa as a way to embed data in human-readable contexts.

    CHAPTER 10 The Hypermedia Zoo There are a lot of hypermedia document formats in active use. Some are designed for very specialized purposes—the people who use them may not even think of them as hypermedia formats. Other hypermedia formats are in such common usage that people don’t really think about them at all. In this chapter, I’ll take you on an educational tour of a “zoo” containing the most popular and most interesting hypermedia formats. I won’t be going into a lot of technical detail. Any one of these formats probably isn’t the one you want to use, and I’ve covered many of them earlier in the book. Many of the formats are still under active development, and their details might change. If you’re interested in one of the zoo’s specimens, the next step is to read its formal specification. My goal is to give you a sense of the many forms hypermedia can take, and to show how many times we’ve tackled the basic problems of representing it. The hypermedia zoo is so full that you probably don’t need to define a brand new media type for your API. You should be able to pick an existing media type and write a profile for it. I’ve organized the hypermedia zoo along the lines of my introduction to hypermedia. There’s a section for domain-specific formats (a la Chapter 5), a section for formats whose primary purpose is to implement the collection pattern (a la Chapter 6), and a section for general hypermedia formats (a la Chapter 7).
