I am looking for measurements that measure international opportunity recognition regarding to entrepreneurial alertness, systematic search, prior knowledge and social network.
Thanks for your help
I believe you should refer to measures used in Global Entrepreneurship Monitor project. They are far from being perfect (in my opinion), but they are intended for cross country comparisons, so they should suit you.Following
- Tony Maine added an answer:20Do scientists tend to gain preferably informations which confirm their opinion and fade out contradictory statements?
I heard (Süddeutsche Zeitung, February 6/7th 2016), that people like to sit in a "reverberation chamber", they are consuming only informations which confirm their opinions, because it feels good to be liked or confirmed.
The social networks tend to strenghten this behavior, especially with the help of new filter systems, which gain new connections by evaluating the personal data of the user.
Is this contradictory to objective thinking and having an open mind?
What about the filtering systems of RG?
I think that it is an excellent sign, that RG contributers are debating this issue so thoroughly. I find it hard to add anything new! However, going back to the original question, I would re-iterate that the use of any filtering techniques that use algorithms may have undesirable results. Algorithms are fine when operating in a defined environment with specific data but they do not work well when in a fuzzy environment with incomplete date. You can use fuzzy algorithms, true, but the results will be even less predictable.
I think that only human beings can adequately monitor the literature of other human beings as only they have the tremendous background of knowledge built up from childhood and life experience which provides a basis for making contextually appropriate selections. Try putting all that in a database - and good luck to whoever has a go! So, viva RG!Following
- Luis Miguel Constantino added an answer:16How do the observations on social networking sites contribute to biodiversity studies; mainly for understudied taxa?
A huge proportion of fauna is unrecorded/ undescribed yet, mainly in invertebrates from tropical region. Hundreds of groups and individuals on Facebook, iNat, Flickr etc, have been photographing animals, some of which have not been recorded in the scientific publications.
While the names provided as identification to these images might not always be correct (as sampling is must for id in many groups), how are they contributing to biodiversity studies?

- Jeanette Novakovich added an answer:22How would you define social media and what tools/platforms/networks/apps/ do you consider social media technologies?
Most often, I see Kaplan and Haenlein's (2010) definition of social media cited in research articles: “A group of Internet- based applications that build on the ideological and technological foundations of Web 2.0 and that allow the creation and exchange of user-generated content” (p. 61).
With respect to social presence and media richness, applications such as collaborative projects (e.g., Wikipedia) and blogs score lowest, as they are often text-based and hence only allow for a relatively simple exchange. On the next level are content communities (e.g., YouTube) and social networking sites (e.g., Facebook) which, in addition to text-based communication, enable the sharing of pictures, videos, and other forms of media. On the highest level are virtual game and social worlds (e.g., World of Warcraft, Second Life), which try to replicate all dimensions of face-to-face interac- tions in a virtual environment” (p. 63).
Recently, Carr and Hayes (2015) published a rather interesting article defining social media in such a way it would stick until 2035:)
Carr, C.T. & Hayes, R.A. (2015). Social Media: Defining, Developing, and Divining, Atlantic Journal of Communication, 23:1, 46-65, DOI: 10.1080/15456870.2015.972282
The definition: "Social media are Internet-based channels that allow users to opportunistically interact and selectively self-present, either in real-time or asynchronously, with both broad and narrow audiences who derive value from user-generated content and the perception of interaction with others” (p. 50).
Social network sites (e.g., Facebook, QQ, GoogleC, YouTube, Yelp, Pheed) Professional network sites (e.g., LinkedIn, IBM’s Beehive) Chatboards & discussion for a Social/Casual games (e.g., Farmville) Wiki “Talk” pages Tinder Instagram Wanelo Yik Yak \

- Rui Sarmento added an answer:8What Libraries and approaches do you suggest for constructing large social network graphs?
Hi all, we're considering different libraries and approaches for the construction of large sized graphs (using Twitter data) - upon construction graph algorithms will be evaluated, so the purpose is more for knowledge discovery rather than visualization.
Currently, it takes 4 hours to generate a graph for a twitter data set that has 21 days worth of twitter data.
1. Which would you recommend, Node4J or Jung, for this purpose?
2. Would HaDoop be a good choice to spread the construction task across different machines in order to save time?
3. How can we store a very large graph in memory , and how can it be made persistent?
Dear Chiung Ching Ho,
We've been researching streaming algorithms and visualization methods or tools for online social networks visualization. Feel free to check our research. If you need any help I'll be gald to provide further assistance.

- Pablo Santana Mansilla added an answer:3How to train a machine automatically by which it understands free text written in social networks?
Topic from sentiment analysis under stating code mix data mainly on Indian language, I am facing the issue if my dictionary is exhausted, how to decide which word is positive or negative? So I want train my system automatically to know which word is negative or positive.
If you want to classify every sentence on a message or every message I think you could follow two approaches:
1) The simplest way is to look for positive or negative words when you process the sentences o messages. It means you do not need to build a machine learning classifier. To know which words are considered positive or negative you would need to make a bibliographic revision. For example the article “Using Machine Learning Techniques to Analyze
and Support Mediation of Student E-Discussions” by Bruce M. McLaren describes an approach to process e-discussions. One of the attributes of the e-discussions is the number of positive and negative terms but McLaren works with English text. Once you determine positive and negative words it may be useful analyze the synonyms.
2) The second way is to build a machine learning classifier. In this case you need to work with some experts on the kind of data you are analyzing so as to they associate a category (positive or negative) to each sentence or message. Taking into account your data set is made of text on different language, during the pre processing it is possible you need to apply stemming, POST, stop words removal, etc., algorithms specific for each language. Furthermore, try to build classifiers with all machine learning algorithms available on the data or text mining software you are working. This way you will be able to compare and chose the algorithm with the best performance.Following
- Andreas Meier added an answer:70What media sources do you trust most to be well informed on political matters?
Do you trust some specific…
--Newspapers (web based or printed)
--Radio or TV programs
--Social networking sites.
--Other Information Websites.
Do you prefer a mix of these sources?
I think a mix of several sources is a healthy approach to consuming news distributors. If you rely on one source without consulting other opinions and perceptions you might adopt the wrong vantage point because several news sources use their plattform for the purpose of propaganda.
Due to this fact I find it difficult to trust news reports these days and therefore try to collect several points of view in order to build my own.Following

I'm trying to model a social network from a software repository, but I haven't found any former investigation about it.
First off, what is in the software depository? and second, what relationship(s) do items in the depository have to each other, or how might they be categorized? once you have this type of information, then you will know the structure of your data, and then you can determine if it is one mode or two mode data, and find other models that fit the type of analysis you could do.Following

The literature on social entrepreneurship indicates that social capital is one of many values brought in by social entreprises. However, this seem to be conflated with social networks.

Over the years the boundaries of the two have become blurred- previous contributions by Alexander and Irene have highlighted the differences and the connections between the two.
I have attached an ONS file that might be of help in your investigation. The ONS site gives you their 'definition' of SC and how Networks are integrated and measured.

- Rashed Heissat added an answer:12Corporate social network; what are the negative social effect?
Hello everyone, i am doing a research on knowledge management and communication in a multinational corporate culture, one side i am very interested in and have been reading on is the implementation social network internally (i.e. Yammer), and the benefits are abundant. but i am also interesting in the other dark side of it; will there be public shaming of fellow colleagues? should be completely formal or allow a sort of relaxed attitude?.
I am very interested in your opinions, or links to studies on this matter :).
Eleanor, Steve, Nick, and Joost thank you so much for the wealth of information you've given me, i had to step away from the internet for a while and i am delighted to come back to these responses!
@Nick indeed one major issue is that the involvement of people on yammer or any other social network might be limited and not corporate wide, but as a first step i would want to see the benefit of it in a small circle of geographically distributed IT team. as for the shamming part i am happy to see that you and others have never experienced any negative shamming, which would help my case in proving the usefulness of internal social media.
@Steve as for the "calculus" idea, it is something on my list which i have seen brilliantly implemented in an App called "Habit RPG", i like their method of calculating the Good and bad habits.
as for the Searching method; Yammer has an inbuilt "hash tag" system which i think in the recent years people have accepted it and use it more often, and it would help categorize discussions and comments and make them very easily searchable.
@Eleanor indeed the "informal" approach employees might take with their managers is one of my concerns, specially in a multi-national corporate where a slight change of tone might be taken as offense in a different cultural setting. i will have to do more research and observation on that one.
again, thank you all for the valuable insights !Following
