  • Introduction • The Last 200 years have strongly revolutionized international transport and communication . • Fax, Phone and most of all the Internet have radically changed our communication possibilities. • More and more communication has been freed from geographical barriers that formerly limited their speed and expansion. • But new means also generate new challenges: – the number of channels has grown exponentially, – communication has changed from unilateral mode to an increasingly fully bilateral communication, – the contents of communication becomes more and more granularwww.sti-innsbruck.at 3 View slide
  • Introduction • Times where a Business unit communicates through only one or two channels with his customers have passed. (Potential) customers: – Search Information on your website – Send an email request – Get advised by a chat-agent – Visit your Business in person – Call your call center – Read your newsletter – Write to you on facebook – Retweet your comment on twitter – … • And the multi-channel monster is still growing!www.sti-innsbruck.at 4 View slide

  • What is Dissemination? • The vital importance of receiving, synthesizing and communicating online information is increasing dramatically in our current digital age. • Dissemination (from the Latin dissēminātus = ―sowing seeds‖, ―scatter wildly in every direction‖) refers to the process of broadcasting a message to the public without direct feedback from the audience. • Takes on the view of the traditional view of communication which involves a sender and a receiver. • The message carrier sends out information to many in a broadcasting system (composed of more than one channels). • Harmsworth et al. (2000) define dissemination as the ―delivering and receiving of a message‖, ―the engagement of an individual in a process‖ and ―the transfer of a process or product‖.

  • What is a dissemination channel? • ―In telecommunications and computer networking, a communication channel, or channel, refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel.‖ (Wikipedia Channel (communications), 2012) • A channel is a means of exchanging information in the on-line space; a ―place‖ where one can find or leave information, whether it is unanimously referred by a URI or addressed through a service.

  • Why Do It? Purpose of Dissemination • Dissemination for Awareness – You wish people to be aware of the work of the project – Useful for those target audiences that do not require a detailed knowledge of the work and is helpful for them to be aware of your activities and results – Will help the ―word of mouth‖ type dissemination and help the organizer build an identity and profile within the community • Dissemination for Understanding – It is aimed at a specific number of groups/audiences that need to be targeted directly – Target audience that benefits from what your project has to offer and have a deeper understanding of the project‘s work • Dissemination for Action – ―Action‖ = change of practice resulting from the adoption of products, materials or approaches offered by the project – Target audience: people that are in the position to ―influence‖ and ―bring about change‖ within their organizations (have skills, knowledge and understanding of your work) Source: http://www.northampton.ac.uk/info/200267/pedagogic-research-and-scholarship/1068/disseminationwww.sti-innsbruck.at 9

  • How Is It Done? Components of Effective Dissemination Plan • Focus on the needs of the target audience and present in an appropriate manner (using appropriate language and information levels). • Include various dissemination methods, including written information, electronic media, and person-to-person contact. • Include both proactive and reactive dissemination channels • Leverage existing resources, relationships, and networks fully. • Include effective quality control mechanisms. • They include sufficient information so that the reader/user can determine the basic principles underlying specific practices and the settings in which these practices may be used most productively. • They establish links to resources that may be needed to implement the information.www.sti-innsbruck.at 11

  • Classification of Dissemination Channels Classified by the type of service they provide: • Static Broadcasting • Dynamic Broadcasting • Sharing • Collaboration • Social Networks • Internet Forums and Discussion Boards • Online Discussion Groups • Semantic-based Dissemination • Overview of Channels Image taken from: http://www.williamsclass.com/SixthScienceWork/Classification/ClassificationNotes/images/classify%20file%20cabinets.jpgwww.sti-innsbruck.at 13
  • Static Broadcasting • Prehistoric methods of dissemination: cave drawings, stories of triumphs on columns and arches, history on pyramids, stones with messages • More modern means: printed press, newspapers, journals • Online static dissemination: websites and homepages….www.sti-innsbruck.at 14
  • Static BroadcastingOnline Broadcasting – Static Websites Homepages / Static Websites • Powerful tool for reaching the target audience and promoting the project • Primarily used to provide information about the project and news of its activities and outcomes. • There is the temptation to present the information in order to ―wow‖ the visitor • BUT!: users tend to prefer good content in a simple, clear and easy-to navigate interface (Keep It Simple, Stupid!) • Although created through a collaborative process, Wiki websites can be considered static forms of online broadcasting as the information contained in them remains the same for long periods of time (i.e. the collaboration process is mostly employed for adding new data or editing/correcting existing one). • Wikipedia is an equally important channel that should be mentioned (although articles are created through a collaborative process) Image taken from: http://www.softicons.comwww.sti-innsbruck.at 15
  • Static Broadcasting Homepage Example Static Website Example The same hotel mentioned on Wikitravel’s entry for Innsbruckwww.sti-innsbruck.at 16

  • Static Broadcasting Static Website Example Entry in Wikipedia for Dieter Fenselwww.sti-innsbruck.at 18
  • Dynamic Broadcasting • Small piece of content that is dependent upon constraints such as time and location. • With Web 2.0 technologies have created dedicated means for publishing streams and interacting with content generated by users. • Blogs: pages where people present their ideas, views and opinions on a particular subject • News: pages where facts or factual information is provided • BUT: Producing high-quality content for a blog on a regularly basis is time-consuming and costly Image taken from: http://www.rgbstock.comwww.sti-innsbruck.at 19
  • Dynamic Broadcasting Good practices: • Each new item has its own URL (in order to be bookmarked, shared, returned in search results, etc.) • Should contain a pointer to a more detailed description about the information items described; • Each new item is archived • Each new item can be indexed by search engines • Each new item is types (through the use of the information model) • Each new item is categorized (using folksonomy) • Each post can be directly shared, liked, added to favorites. • News can be searched for, sorted and filtered • Important news items stay at the top to highlight main announcements Source: http://oc.sti2.at/images/c/c7/STI_International_On-line_Communication_Handbook.pdfwww.sti-innsbruck.at 20
  • Dynamic Broadcasting Channels/Tools – An overview • Examples of tools (organized considering first the length of message and second – the level of interactivity): – News Feeds – Newsletters – Email / Email lists – Microblogs – Blogs – Social networks – Chat and instant messaging applicationswww.sti-innsbruck.at 21
  • Dynamic Broadcasting News Feeds • RSS (Rich Site Summary) Feeds: – a family of web feed formats used to deliver regularly changing web content. – Many websites and blogs offer users the option of subscribing to their RSS feed. – The content is syndicated automatically – the user does not have to visit each website manually – RSS Readers are available for different platforms: • PC readers: Amphetadesk, FeedReader, NewsGator • Web-based readers: My Yahoo, Bloglines, Google Reader – Includes full or summarized text, plus metadata (publishing dates and authorship) Image taken from: http://www.softicons.comwww.sti-innsbruck.at 22

  • Dynamic Broadcasting Newsletters • The newsletter is an instrument used to regularly exchange information among the members of a community • It constitutes the primary means of collecting and spreading the results achieved through network activities. • The main objectives of the Newsletter are: – to report the main activities promoted and undertaken – to widely disseminate information about published papers (position papers, state of the art reviews) of researchers involved in the network. • Website users have the possibility to subscribe to the Newsletter and automatically receive each issue in their mailbox. • Users should have the option of subscribing and unsubscribingwww.sti-innsbruck.at 24
  • Dynamic Broadcastingwww.sti-innsbruck.at 25
  • Dynamic Broadcasting Email/Email lists • Email: means of exchanging digital messages from a sender to one or multiple recipients • (Electronic) Mailing lists: collection of names and (email) addresses used to send material to multiple recipients. – Announcement lists (Newsletters, periodicals, advertising – used primarily as a one-way conduit of information and can be ―posted to‖ by selected people) vs. Discussion lists (any subscriber can post) – Can be self-hosted (e.g. GNU Mailman) or third-party hosted (as part of notifications for Google groups, Yahoo! Groups ) – Requires users to subscribe to the list.www.sti-innsbruck.at 26
  • Dynamic Broadcasting Email/Email lists • Well established means for dissemination within a predetermined group • Requires members to subscribe to a mailing list • Since email lists are mostly not accessible to a wider audience, they should be ignored for external use and focus should be primarily on external means of communication • Email is a good method of sharing information on a one-to-one basis (e.g. mail this website to a friend) • Despite their obvious strength, in the age of information overload and spam, mailing lists will not perform efficiently if they are not carefully targeted and offer recipients the option to subscribe/ unsubscribe whenever they wish. • Note!: there are legal requirements associated with the possibility to subscribe/unsubscribe and the storage of and access to personal data [European Commission, n.d.]www.sti-innsbruck.at 27
  • Dynamic Broadcasting Microblogging • Broadcast medium similar to blogs • The difference between microblogging and an actual blog is in the size of the content in both actual and aggregate files. • The actual messages are called microposts. • Commercial microblogs exist to promote websites, services, products or collaboration within an organization. • Can contain a wide range of topics. • Low effort to participate.www.sti-innsbruck.at 28
  • Dynamic Broadcasting Microblogging • Twitter – Social networking service and microblogging service – users can send messages of a maximum length of 140 characters, follow other users, and create interest lists. – Widely used means of dissemination – Significant space limitations: 140 characters or less – Twitts are publicly visible by default (senders can restrict the access control) – Users can tweet using the website, external APIs or SMS – The service is free – Users may subscribe to other users tweets – this is known as following and subscribers are known as followers or tweepswww.sti-innsbruck.at 29
  • Dynamic Broadcastingwww.sti-innsbruck.at 30

  • Dynamic Broadcastingwww.sti-innsbruck.at 32
  • Dynamic Broadcasting Blogs • Alternatively called web logs or weblogs • A weblog is a hierarchy of text, images, media objects and data, arranged chronologically, that can be viewed in an HTML browser. * • In some situations, it is the creator‘s online journal. • The activity of updating a blog is ―blogging‖ and someone who keeps a blog is a ―blogger.‖ • Items are posted on a regular basis and displayed in reverse chronological order. • Individual articles on a blog are called ―blog posts,‖ ―posts‖ or ―entries‖. • Blogs are usually (but not always) written by one person and are updated pretty regularly. • Blogs are often (but not always) written on a particular topic. *http://blogs.law.harvard.edu/whatmakesaweblogaweblog.html Images taken from: http://www.softicons.comwww.sti-innsbruck.at 33
  • Dynamic Broadcastingwww.sti-innsbruck.at 34
  • Dynamic Broadcasting Using Social Networks • Social network content is dynamic in the sense that it provides information that will expire after a period of time and be important only for that period and moment; • However, as it focuses more on creating communities than on the temporal and geospatial aspect of the information, it will be discussed in detail in Section 4.5.www.sti-innsbruck.at 35
  • Dynamic Broadcasting Chat Applications • one-to-one basis • Instant method of communication • Text-based chat, video chat, one vs. multiple receivers, web-based etc. • Can be applied to a small number of people (it does not scale well for large groups – it is impossible to follow who is discussion when more than one member of the discussion group is writing/typing simultaneously) • It is not useful as a method of dissemination due to its instant and intrusive nature • In order to be used as a dissemination method, the user must add the message sender to the contact listwww.sti-innsbruck.at 36

  • Semantic Based Dissemination What is semantic web? • An extension of the current web in which information is given a well defined meaning, better enabling computers and people to work in cooperationwww.sti-innsbruck.at 84
  • Semantic Based Dissemination Why use semantics? • Problems with current day search engines: – Recall issues – Results are dependent on the vocabulary – Results are single Web pages – Human involvement is necessary for result interpretation – Results of Web searches are not readily accessible by other software tools • Content is not machine-readable: – It is difficult to distinguish between: ―I am a professor of computer science.‖ and ―You may think, I am a professor of computer science. Well, actually. . .‖www.sti-innsbruck.at 85
  • Semantic Based Dissemination The Semantic Web Approach • Represent Web content in a form that is more easily machine-processable. • Use intelligent techniques to take advantage of these representations. • Knowledge will be organized in conceptual spaces according to its meaning. • Automated tools for maintenance and knowledge discovery • Semantic query answering • Query answering over several documents • Defining who may view certain parts of information (even parts of documents) will be possible. • Semantic Web does not rely on text-based manipulation, but rather on machine- processable metadatawww.sti-innsbruck.at 86

  • Semantic Based Dissemination Format – RDFa • Is a W3C Recommendation that adds a set of attribute-level extensions to XHTML for embedding rich metadata within Web documents. • Adds a set of attribute-level extensions to XHTML enabling the embedding of RDF triples; • Integrates best with the W3C meta data stack built on top of RDF • Benefits [Wikipedia RDFa, n.d.]: – Publisher independence: each website can use its own standards; – Data reuse: data is not duplicated - separate XML/HTML sections are not required for the same content; – Self containment: HTML and RDF are separated; – Schema modularity: attributes are reusable; – Evolv-ability: additional fields can be added and XML transforms can extract the semantics of the data from an XHTML file; – Web accessibility: more information is available to assistive technology. • Disadvantage: the uptake of the technology is hampered by the web- master‘s lack of familiarity with this technology stackwww.sti-innsbruck.at 96
  • Semantic Based Dissemination Format – RDFa • RDFa Attributes: – about and src – a URI or CURIE specifying the resource the metadata is about – rel and rev – specifying a relationship or reverse-relationship with another resource – href and resource – specifying the partner resource – property – specifying a property for the content of an element – content – optional attribute that overrides the content of the element when using the property attribute – datatype – optional attribute that specifies the datatype of text specified for use with the property attribute – typeof – optional attribute that specifies the RDF type(s) of the subject (the resource that the metadata is about).www.sti-innsbruck.at 97

  • Semantic Based Dissemination OWL Sublanguages • The W3C-endorsed OWL specification includes the definition of three variants of OWL, with different levels of expressiveness (ordered by increasing expressiveness): – OWL Lite - originally intended to support those users primarily needing a classification hierarchy and simple constraints Each of these sublanguage – OWL DL - was designed to provide the maximum expressiveness is a syntactic extension of possible while retaining computational completeness, decidability, and the availability of practical reasoning algorithms. its simpler predecessor. – OWL Full - designed to preserve some compatibility with RDF Schema • The following set of relations hold. Their inverses do not. – Every legal OWL Lite ontology is a legal OWL DL ontology. – Every legal OWL DL ontology is a legal OWL Full ontology. – Every valid OWL Lite conclusion is a valid OWL DL conclusion. – Every valid OWL DL conclusion is a valid OWL Full conclusion. • Development of OWL Lite tools has thus proven almost as difficult as development of tools for OWL DL, and OWL Lite is not widely used Source: McGuinness, COGNA October 3, 2003www.sti-innsbruck.at 100

  • Semantic Based Dissemination Format – RIF • A collection of dialects (rigorously defined rule languages) • Intended to facilitate rule sharing and exchange • RIF framework is a set of rigorous guidelines for constructing RIF dialects in a consistent manner • The RIF framework includes several aspects: – Syntactic framework – Semantic framework – XML framework • RIF can be used to map between vocabularies (one of the proposed use cases) Source: Michael Kifer State University of New York at Stony Brookwww.sti-innsbruck.at 106
  • Semantic Based Dissemination Format – RIF • The standard RIF dialects are: – Core - the fundamental RIF language. It is designed to be the common subset of most rule engines. (It provides "safe" positive datalog with builtins.) – BLD (Basic Logic Dialect) - adds a few things that Core doesnt have: logic functions, equality in the then-part, and named arguments. (This is positive Horn logic, with equality and builtins.) – PRD (Production Rules Dialect) - adds a notion of forward-chaining rules, where a rule fires and then performs some action, such as adding more information to the store or retracting some information. • Although RIF dialects were designed primarily for interchange, each dialect is a standard rule language and can be used even when portability and interchange are not required. • The XML syntax is the only one defined as a standard for interchange. Various presentation syntaxes are used in the specification, but they are not recommended for sending between different systems.

  • Semantic Based Dissemination Format – Microformats • Directly use meta tags of XHTML to embed semantic information in web documents; • Microformats were developed as a competing approach directly using some existing HTML tags to include meta data in HTML documents • As of 2010, microformats allow the encoding and extraction of events, contact information, social relationships and so on • Advantages: – you can publish a single, human readable version of your information in HTML and then make it machine readable with the addition of a few standard class names – No need to learn another language – Easy to add • However: they overload the class tag which causes problems for some parsers as it makes semantic information and styling markup hard to differentiatewww.sti-innsbruck.at 109
  • Semantic Based Dissemination Format - Microformats • Example <ul class="vcard"> <li class="fn">Joe Doe</li> <li class="org">The Example Company</li> <li class="tel">604-555-1234</li> <li><a class="url“ href="http://example.com/">http://example.com/</a></li> </ul>www.sti-innsbruck.at 110
  • Semantic Based Dissemination Format – Microdata • Use HTML5 elements to include semantic descriptions into web documents aiming to replace RDFa and Microformats. • Introduce new tag attributes to include semantic data into HTML • Unless you know that your target consumer only accepts RDFa, you are probably best going with microdata. • While many RDFa-consuming services (such as the semantic search engine Sindice) also accept microdata, microdata-consuming services are less likely to accept RDFa. • Advantages: – the variable groupings of data within published area tables may not be the detail required for a particular application (e.g. age group, ethnic group or occupational classification). – the cross-tabulations of variables available in area tables may not be those needed for a study (e.g. counts of individuals by age and ethnic group and occupation).www.sti-innsbruck.at 111
  • Semantic Based Dissemination Format – Microdata • Examples: – Google may use microdata in its results pages: – Opera from version 11.60 is the only current stable release of a browser that supports microdata: – MicrodataJS is a JavaScript library and jQuery plugin that emulates the DOM API.www.sti-innsbruck.at 112

  • Semantic Based Dissemination Format – RDF • The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. • RDF provides a common framework for expressing information so it can be exchanged between applications without loss of meaning. • It is based on the idea of identifying things using Web identifiers (called Uniform Resource Identifiers, or URIs) and describing resources in terms of simple properties and property values • Thus, RDF can represent simple statements about resources as a graph of nodes and arcs representing the resources, and their properties and values. • It specifically supports the evolution of schemas over time without requiring all the data consumers to be changed Source: http://www.iis.sinica.edu.tw/~trc/public/courses/Fall2008/week15/slide-w15.html#%287%29www.sti-innsbruck.at 115
  • Semantic Based Dissemination Format – RDF • Based on triples <subject, predicate, object> • An RDF triple contains three components: – the subject, which is an RDF URI reference or a blank node – the predicate, which is an RDF URI reference – the object, which is an RDF URI reference, a literal or a blank node – An RDF triple is conventionally written in the order subject, predicate, object. – The predicate is also known as the property of the triple. • Triple data model: <subject, predicate, object> – Subject: Resource or blank node – Predicate: Property – Object: Resource (or collection of resources), literal or blank node • Example: <ex:john, ex:father-of, ex:bill>www.sti-innsbruck.at 116
  • Semantic Based Dissemination Format – RDF • An RDF graph is a set of RDF triples. • The set of nodes of an RDF graph is the set of subjects and objects of triples in the graph. • Person ages (:age) and favorite friends (:fav) Properties encoded as XML entities: <rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/ 22-rdf-syntax-ns#" xmlns:example="http://fake.host.edu/e xample-schema#"> <example:Person> <example:name>Smith</example:name> <example:age>21</example:age> <example:fav>Jones</example> </example:Person> </rdf:RDF>www.sti-innsbruck.at 117

  • Pitfalls of Dissemination • Online dissemination methods are forms of electronic marketing, BUT there are important differences between electronic spam and conventional marketing techniques. • For instance, common sense dictates that there‘s no reason to send an advertisement to somebody who can‘t use the product being advertised (e.g. presenting advantages of cat food to dog owners). • The method of dissemination must be particularly crafted for the target audience (e.g. a message containing a large amount of technical details should not be sent to a partner that cannot understand such details) • The method of dissemination must be particularly crafted for the channel selected to disseminate: the message should be shared on channels that permit it, otherwise it will be considered spam. • A dissemination channel should not be intrusive: a member should be asked before being subscribed to a specific list, and should have the option to unsubscribe and re-subscribe whenever he wishes sowww.sti-innsbruck.at 141
  • Pitfalls of Dissemination • The user must not be overloaded with information and must have the option of managing the content received (e.g. receive daily/weekly digests instead of numerous messages containing a single message) • Close attention should be paid to the messages that are disseminated: elements that are not of utmost important should be just posted on the website regularly (and provide a single newsletter directing the user to the site). • Posting elements that are not interesting for a user will be considered spam (in essence, spam is a message from someone else that the receiver did not ask for and does not want to have). • The receiver should not be buried under a large number of messages – it will create frustration as the important messages become harder to observe. • When using chat applications as methods of dissemination, certain etiquette elements must be taken into consideration: – Mass messages containing advertising are considered rude – A discrete way of disseminating is using the status updatewww.sti-innsbruck.at 142

  • What is Impact and Feedback Feedback of dissemination • Refers to the response of an audience to a message or activity. • Giving the audience a chance to provide feedback is crucial for maintaining an open communication climate. • ―Feedback refers to a relationship between the behavior of the speaker, the response of the listener and the effect of the response on the further behavior of the speaker. … In a sense, we may say that feedback, in order to be feedback, must be used as feedback.‖ Theodore Clevenger, Jr., and Jack Matthews – “Feedback” – “Communication theory” edited by C.David Mortenser. • Feedback should be measured and analysed.www.sti-innsbruck.at 148
  • What is Impact and Feedback Measuring the feedback of the dissemination activities • Increased understanding of the impact of the dissemination processes. – The generation of reports, regarding the dissemination activities, helps an organisation to understand in deep the impact of their work and products to the audience by knowing what people do not find attractive and useful. • Evaluate current online and social network strategies. – It is always important to evaluate a strategy and specify the lessons learned for future use. • Look forward and plan the next business steps and objectives based on the effectiveness of the current activities. – Modify the current dissemination activities according to the reports in order to be more effective in the future and our efforts more productive.www.sti-innsbruck.at 149
  • What is Impact and Feedback Measuring the feedback of the dissemination activities • To ensure that the message disseminated has been seen by the target audience. – By measuring the impact of the dissemination, we could be aware of the visibility that our message achieved. • To verify whether the message has been understood by the target audience. – The disseminated message may be well distributed and visible, but not understood by the audience in the way that the enterprise would like to. • To quantify the reach of the dissemination. – It is important to be able to produce reports with metrics about the effectiveness of the dissemination. This is realizable only by establishing ways to measure the impact.www.sti-innsbruck.at 150
  • What is Impact and Feedback What should we measure to specify the feedback? • Social Media Exposure – How many people did you reach with your message? • Appeal of your message – How many people listened to the entire message? – If the majority of people stopped listening to your message, when did they stop? Was it due to the content, the implementation of the message or the medium? • Engagement – How many people actually reacted to your message? It is important to find out how many people reacted after the dissemination reached them. Did they forward the message to their social circle?www.sti-innsbruck.at 151
  • What is Impact and Feedback What should we measure to specify the feedback? • Influence – Measure how influential the people who engaged with, and reacted to your message. This reflects the influence of the enterprise. The enterprise should be sure the messages are reaching different kinds of people, including average users and influential users. • Message converted to action – The ultimate goal of the enterprise is to monetize the dissemination of products and services. – Measuring how the disseminated messages were converted to transactional actions. – What was the Return On Investment (ROI) and the Social Return On Investment (SROI)www.sti-innsbruck.at 152
