Dr ElBaradei told Mr Blair that: “Any war would risk radicalising the region. It should be UN-controlled.”

What follows are the visualizations created using Leximancer software of the Iraq Inquiry Report (all 12 Volumes over 2 million words)and also referred to as the Chilcot Report. The Report of the Iraq Inquiry was published on Wednesday 6 July 2016. Sir John Chilcot’s public statement can be read here.
Leximancer is a computer software that conducts quantitative content analysis using a machine learning technique. It learns what the main concepts are in a text and how they relate to each other. It conducts a thematic analysis and a relational (or semantic) analysis of the textual data. Leximancer provides word frequency counts and co-occurrence counts of concepts present in the tweets. It is:
[A] Method for transforming lexical co-occurrence information from natural language into semantic patterns in an unsupervised manner. It employs two stages of co-occurrence information extraction— semantic and relational—using a different algorithm for each stage. The algorithms used are statistical, but they employ nonlinear dynamics and machine learning. (Smith and Humphreys, p. 26)
Once a concept has been identified by the machine learning process, Leximancer then creates a thesaurus of words that are associated with that concept giving the ‘concept its semantic or definitional content’.

How to read the Leximancer Map
A Leximancer ‘Theme’ is a group or cluster of Concepts that have some commonality or connectedness as seen from their close proximity on the Concept Map. The size of the Theme circle has no bearing as to its prevalence or importance in the text; the circles are merely boundaries. Prevalence is determined by the number of Concepts present in the Theme and this is indicated in the Thematic Report. The histogram bars in the Thematic Report are color-coded (hot – cold) to further signify the prevalence of the Theme – and this color is carried through to the Theme circle boundary color.

attacks (Hits: 1458)
“Once Saddam is gone there is likely to be widespread and apparently random violence between Iraqis. Specific attacks against Coalition Forces are likely to come later (perhaps some months later) if particular individuals or groups feel they are being cut out of contracts, administration positions etc.”
I can not recommend this article enough.
Very well written and covers the appropriate literature and software surrounding social media mining and analysis for social scientists.
I also completely agree that what is needed is a critical engagement with social media as well as other Big (Social) Data by non computer programmers, mathematicians and physicists in order to generate rich and detailed accounts of what is happening…
There is a need for critical data analysis, utilizing digital methods for capturing and analyzing social media according to platform dynamics. There is also a need for enriching data analytics with more traditional methodologies to provide thick description (Felt, 2016).

Social media posts are full of potential for data mining and analysis. Recognizing this potential, platform providers increasingly restrict free access to such data. This shift provides new challenges for social scientists and other non-profit researchers who seek to analyze public posts with a purpose of better understanding human interaction and improving the human condition. This paper seeks to outline some of the recent changes in social media data analysis, with a focus on Twitter, specifically. Using Twitter data from a 24-hour period following The Sisters in Spirit Candlelight Vigil, sponsored by the Native Women’s Association of Canada, this article compares three free-use Twitter application programming interfaces for capturing tweets and enabling analysis. Although recent Twitter data restrictions limit free access to tweets, there are many dynamic options for social scientists to choose from in the capture and analysis of Twitter and other social media platform data. This paper calls for critical social media data analytics combined with traditional, qualitative methods to address the developing ‘data gold rush.’

An Analysis of Big Data on Health (pdf file of slides)
The abstract for what is a WORK IN PROGRESS
can be accessed here….
The ‘social’ has always been a commercial and scientific resource – now in the digital age the competition regarding claims to which disciplines have justified understandings of this domain have intensified. The social sciences need to defend their subject area in order to preserve it. An application of the netnographic approach (Kozinets, 2010), social network analysis, data mining and machine-learning tools to highlight the certainties and uncertainties of Big Data and the Health Industry in order to start the process of uncovering the social and cultural forces that they are appropriating. What follows is the application of the tools of Big Data analytics on those that conduct Big Data analytics. There are competing discourses surrounding ‘Big Data’ and Health. On the one hand business, marketing and advertising interests are promoting Big Data as information that no longer requires theory or the scientific methodologies of old. On the other are voices from the academy; digital humanities and computational social sciences that wish to benefit from the volumes of available data. It is these (and other) competing discourses that are the target of this research. This paper argues that those engaged in ‘data without theory’ are generating a relational social mechanism similar to that of self-fulfilling prophesies of Merton, the network effects of Coleman and the bandwagon effects of Granovetter (Donati, 2015:66) and leaving no room for critique.

“what we have defined as keyword hashtags constitute a very different way of using hashtags – largely for emphasis rather than to institute an issue public –, and the uses and utility of such hashtags remain to be explored in greater detail still.”
by Axel Bruns, Brenda Moon, Avijit Paul & Felix Münch (2016)
Twitter’s hashtag functionality is now used for a very wide variety of purposes, from covering crises and other breaking news events through gathering an instant community around shared media texts (such as sporting events and TV broadcasts) to signalling emotive states from amusement to despair. These divergent uses of the hashtag are increasingly recognised in the literature, with attention paid especially to the ability for hashtags to facilitate the creation of ad hoc or hashtag publics. A more comprehensive understanding of these different uses of hashtags has yet to be developed, however.
Previous research has explored the potential for a systematic analysis of the quantitative metrics that could be generated from processing a series of hashtag datasets. Such research found, for example, that crisis-related hashtags exhibited a significantly larger incidence of retweets and tweets containing URLs than hashtags relating to televised events, and on this basis hypothesised that the information-seeking and -sharing behaviours of Twitter users in such different contexts were substantially divergent.
This article updates such study and their methodology by examining the communicative metrics of a considerably larger and more diverse number of hashtag datasets, compiled over the past five years. This provides an opportunity both to confirm earlier findings, as well as to explore whether hashtag use practices may have shifted subsequently as Twitter’s userbase has developed further; it also enables the identification of further hashtag types beyond the “crisis” and “mainstream media event” types outlined to date. The article also explores the presence of such patterns beyond recognised hashtags, by incorporating an analysis of a number of keyword-based datasets.
This large-scale, comparative approach contributes towards the establishment of a more comprehensive typology of hashtags and their publics, and the metrics it describes will also be able to be used to classify new hashtags emerging in the future. In turn, this may enable researchers to develop systems for automatically distinguishing newly trending topics into a number of event types, which may be useful for example for the automatic detection of acute crises and other breaking news events.

The Forbes 2015’s Billionaires (2015). Forbes ranks more than 1,800 billionaires and these are their company, and affilations with Government Bodies etc – This list was then adapted by LittleSis http://littlesis.org/lists/846-the-world-s-billionaires-2015/members . I have then used it to construct a network which I’ve then visualised using Gephi.

The Forbes Rich List and their Connections
It follows the same principle as those laid out here…
Forbes magazine has been publishing the list of The World’s Most Powerful People since 2009. The number of people in the list is proportional to the global population with the ratio being one slot for every 100 million people on Earth. When the list started in 2009, there were 67 people on the list and the latest list from year 2014 had 72 people. According for Forbes, the list is calculated based on the person’s influence over lots of other people (e.g. Pope Francis, Wal-Mart CEO, Doug McMillon), financial resources controlled by the people (e.g. GDP, market capitalization, profits, assets, revenues and net worth), power in multiple spheres (e.g. Bill Gates), active use of power by the people (e.g. Vladimir Putin). While this list gives a snapshot of global ranking, it does not reveal information about past and present network connections and inter-linkages between people and organisations, the spread of power across the network, information about key entities who act as network intermediaries for power and which cluster of entities are most prominent in this global power structure. This is where we complement the Forbes data with LittleSis, which is a database of who-knows-who at the heights of business and government. LittleSis has information of the global rich and powerful such as past and present organizational affiliations (employment, directorships, memberships, alumni networks), donations (political contributions, grants), social connections (family ties, mentorships, friendships), professional connections (partnerships, supervisory relationships), services/contracts (legal representation, government contracts, lobbying services) etc. http://www.datasciencecentral.com/profiles/blogs/the-alternative-list-of-global-power-elite
