Doctoral seminar (DBIS RWTH Aachen)

Editor's Notes

• #4: Give a clear idea about long tail: in order to fulfill the needs of all needs the clear needs should be found., needs on the abstract level - like ANT proposes Does a community fill a niche: if a community consistent and clearly defined. Basing on CoP concept: does a community has interactions between members, has a goal, policies, common understanding And if yes: what is it like? Self-monitoring of the community . Starting from simple about how many members and how many links between members, e.g. mails/posts. Following with top concepts and keywords the community is discussing, type of social networks the members of the community organize, knowledge creation activities of memembers Will it be good or bad, how it will be if the goals of communities will be fullfilled. Surely it sounds as magic to know what happens in the future but at least some methods may allows us to have a look in the future Different communities The result depend on the people who around me, my community, their interest, my interest and intensions Community information systems!!!!! Not a learner alone! Community is under the focus! Am Besten wäre es wenn du noch konkretere Beispiele geben könntest wie Ich kenn mich aus mit ... und will aber jetzt was lernen über ... -> wer oder was ist interessant für mich? Community – we are interested in community
• #5: Reflect according to community idea!!! Need to show how all the stuff that was done and is been doing now connected with each other and self-analysis/self-reflection phases Focus of my research is learning communities. It means the goal of the communities and its members are to learn. To learn from learning resources which are people, communities and documents. To deepen the research i‘m focusing on e-learning communities, those use different media for sharing resources, communicating, knowledge creation and other actions. In the task of analysis of e-learning communities one has to deal with a huge number of learning resources, learners, their organization. The purpose of my analysis is to help learners and communities to analysis themselves (self-analysis) and to reflect according to changes in the environment Thus we have to deal with a complex computer science task which consist of modeling of learners and communities (imagination) patterns extraction based on real situations simulation of models (what happens if) recommendations of learning partners, learning resources
• #6: But we need to consider our reality that change every second. Drivers and obstacles that we name disturbances have impacts on persons and communities We have to reflect the reality and in order to do it we have to understand how the reality do look like. We can do social network analysis, emotion extractions, natural language processing, extraction of interactions in order to get an idea about reality. Basing on these information we can find what the roles we possess, what community and reflecting our goal we can change the context of the environment so that it will suit goals and current situation.
• #7: Hovewer if we are considering self-regulated learning and personal environment “I” is very important there!!! Your intensions, your information - they play a role!!!but not only - because we are social beeings, we are parts of communities- many of them So we have a dilemma how to differentiate between knowlegde that identify us within a community with the knowledge that we possess Interactions that are happening between a person and a community can form a border of the intentions and information of communities and persons Practices in communities are usage of system Activity theory that is focusing on how the persons interact can contribute to learner interaction model : a try of using CoP concept and Engöstrom model
• #8: Delete: perform an additional task/ change: Tools- to Media The person responsible for competence management and development (the course manager or the teacher of the course) can help the learner to focus on professional competences so that the learner can better succeed in the course. The learner can be asked to handle more often with Artefacts, e.g., to create a knowledge map about a topic from the course. Afterwards, the learner can discuss his Artefact in a Discussion Forum as according to the communicator pattern, it is the part of learning he enjoys to do. While this is a competence development application, the next scenario is an example of competence management . On the other hand, if the teacher of the course needs to organize an event for the students of the course, the learner is the right person for the task. The result of the application of the SNA pattern-based framework is depicted in Figure 5.2. Here we use the Role i* notation for illustrating the communicator pattern. Other test-bed scenarios have been considered but have not been shown here because of lack of space. In order to apply the methods of the SNA pattern-based framework we need to define collaboration networks that exist in the scenario. There are at least two two types of CNs possible: Learner - Learner CNs and Learner-Teacher CNs. With the help of the framework we can identify a learner network characteristics in Learner - Learner CNs, in Learner-Teacher CN and a teacher network characteristics in Learner-Teacher CN. Based on numerous network characteristics it is possible to answer whether the learner’s status in Learner-Teacher or the status in Learner - Learner CNs correlate with the learner’s marks. As a result it can be discovered that the learner is too communicative ( communicator pattern) but pays not enough attention to using learning material ( create/find/reuse task for Artefact, low marks for created Artefacts ).
• #9: Add information about number of entities, time and types Explain the difference between different networks Next page – scale free/ small world networks Betweenees degree / density etc.
• #10: Mediabase – focus on community There are not a one mediabase but a lot of Each community has a mediabase/mediabase commander, and MBC is connected to LAS

• #12: Future!!! On the second figure you can see one of the users - red node that is connected with an expert(yellow node) and has connections with some other peers, the green ones are those who have just appeared in the community and the orange one are those that are the bridges in communication between the red node and other nodes connected with the organge node. The person who represents the node is quiet ordinary user of a community even he has a power under both green nodes. The communication of green nodes with other community participants is dependant on the red node. In the scope of our presentation the requirements produced by such red nodes are more valuable than the requirements of green nodes. We consider as well how the community develops within a time and who will play an important role there in a year. In the third figure is the same community visualized with the same person from the second figure. As you see the red node has achieved to be connected to more people (just newcomers, experts and other members). In the overall analysis it was shown that he has the forth highest degree and betweenness centraliy – thus the person has extened his social capital , presence in community. In the scope of SRE it is important to discover such people as they provide the needs of nisches of users. Different industry terms like mempory system, visual processing problems Medical condition: autism, syndrome
• #14: Establishment fo XMPP experience group Provision of research data sets as cloud computing service Xmmp extension protocol for the mpeg query format Provide research data sets as cloud services New learning science: neuroscience, psychology, machine learning and education
• #15: Conslusions shoud be added! Should be updated!!!!! Social are seen as social ties. When we see the changes in system , those were engaged by social ties and other way around. For example, the criminal can say that he has a bad parent but it doesn‘t automatically translated.
