  • Such a powerful quotation, thanks for sharing Jesús!

  • Lesley, because the data is usually made available by the platform itself, the consent is part of the user agreement, for example in Twitter:

  • Yes, whenever the direction is changed, it will change the in degree and the out degree. But the total degree is the same.

  • True, in fact there are a lot of discussions within the scientific community about the ethical aspect about using data collected from social media. As a matter of fact, it is common that researchers anonymise the data if they decide to release it.

  • Ruth and Michelle, thanks for your comments, to sum up your thoughts I would say it is either influence measured in a certain way, or it might not be a true influencer but the fact that a story has value in itself which will attract a huge number of 'ordinary users' to share it.

  • Michelle, all of the points you mentioned are valid, however, their effect varies depending on the personalities. It is a beneficial game if you know how to play it without compromising your time, privacy and 'sanity', I think!

  • Hi Adam, I'm sorry that you are finding the content difficult to understand, but please do not hesitate asking questions, let us know if we can help you with it.

  • I agree, before the emergence of social media people had a little more time to write blogs and engage in long discussions on online forums and such. But I think blogs still maintain their importance as personal portfolios for those who have a little more than 140 characters allowed by Twitter.

  • Alexis, I think you're absolutely right! focus is a key factor, it increases the blog's coherence and makes it easier for the person to manage and produce content.

  • Thanks Ruth for sharing your thoughts with us!

  • All the best Aimee, we're glad the course was an eye opener for you about how social media can effectively be used for professional purposes.

  • Hi Rhyanne, welcome to the course, week 2 covers the topics of promoting businesses and charities on a tight budget. we hope you'll enjoy it!

  • Sandra, the focus of week 2 is about using social media for professional purposes, we hope you'll enjoy it!

  • Hi Maja, I understand where you're coming from. I hope this course will allow you to see what social media can offer :)

  • Candace, we are glad that you've enjoyed the course! We hope that you'll enjoy week 2 as much! Cheers to you! :)

  • Pete this sentence is very true: "smarter companies recognise that likes aren't sales but have found ways to take folk onto individual journeys".
    I would argue that smarter companies usually have a strong presence on social media but they differentiate between popularity (measured by likes and numbers of followers) and actual revenue. They invest in social...

  • Hi everyone,
    If you would like to have unlimited access to the course materials, after 4 Jun 2017, you can upgrade by following this link:
    In addition to unlimited access, you will receive a digital Certificate of Achievement and transcript when you complete the course.

  • eLaine, the complexity of heterogeneity in the network complicates the analysis of such network(s). Speaking from experience, they maintain their integrity by reacting to customers' demands. I think they assume everything is right, until proven wrong. Whenever something goes wrong and a customer complains, it triggers the negotiations between Amazon and the...

  • Well, often in machine learning a number of features are combined to make such predictions. In this paper only one feature, i.e., the length of the answer, was considered in the prediction task. Maybe declaring that 62 is a good predictor is not very accurate. However, it just means that for 62% cases the length of the answer was useful to predict the...

  • True, I think it depends on the social media that is popular among the intended audience. What differentiate these groups of users might be their demographics or interests. For instance, Instagram is a great social media foe users interested in photography and travel, whilst Twitter might be more useful for politicians.

  • Absolutely correct, I think the Apple vs Android camps are good examples for such communities. They actively engage on social media, some of them take it to the next level by voluntarily creating videos on YouTube or write blog posts to unbox products or promote them.

  • For all of you who just joined us in the course, welcome on board!
    We are in week 2, but take your time and work your way through the course at your own pace. We hope you will enjoy it!

  • eLaine, welcome to the course! We hope you'll enjoy it, learn some insights and get inspired by its content!

  • Great, please share your thoughts after going through the tasks in this week, we would like to hear from you .

  • I completely agree with you, having a professional profile by the means of a blog, Twitter account, or Linked might be better than Facebook. Though they differ in the amount of effort they require because maintaining a blog is more time consuming than posting on Twitter.

  • That is an interesting example of recruiting people via social media, thanks for sharing with us. If I may ask you, how did you locate these individuals?

  • Exactly! speaking for myself, I was part of the mentoring teams in several futurelearn courses by the University of Southampton. I always enjoyed reading the discussions, sometimes I just observe and like comments other times I engage with the learners. As you said, it is fascinating to hear from people with different opinions, backgrounds and nationalities!

  • Great! I'm glad it was helpful :)

  • Well, I do agree, Twitter for example restricted full access to its data to a hanful of services such as Gnip, which you'll have to pay to get the data to be analysed for various purposes. They also use ads and they allow their users to promote their content. All are parts of their business model, but I'm curious to hear your thoughts about implementing a...

  • Yes, it is said that between any two persons on earth there are six degrees, if we contact the other person directly it will demolish that separation altogether.

  • Hi Mies,
    on Yahoo Answers, the asker gets to rate one answer as the best one.
    Well, the researcher used the length of the answer only to predict whether it will be the best answer, using this measure (the length) the prediction accuracy was 62%. This simply means that the length of the answer alone is a good predictor that the answer will be picked by the...

  • Katia, do you mean posting 'fake' jobs adverts?

  • Pete, thank you very much, well-explained and really interesting analysis.
    The heterogeneity of both nodes and edges complicates the network as a whole. which consequently would complicate any analysis done on it. I'm wondering if it can be divided into several networks instead?

  • Very good points Susan, quick responses are extremely important in such websites, thanks!

  • Absolutely true, the context is really important in all aspects of social media analysis. The idea of using the correlation between mail traffic and sales is very accurate as a measure.

  • Clustering co-efficient is measured around one node, i.e., if your friends are connected to each other you will have a high clustering around you. If they are not connected to each other the clustering co-efficient of your node will be low.

  • That is a really good example Kristie! Thanks!

  • Well, the thing about degree distributions is more general, i.e., the majority of nodes have small degree, and only few of them have extremely higher degrees, other nodes have degrees between those two ends. Thus, collectively the distribution is power law.

  • I would add that it is not only about their connections but also it depends on the content they share, good content attracts more connections.

  • Well I think social media is the medium through which we connect to each other, it is more like a container I would say.

  • No worries Su, I hope it helped!
