Using social media monitoring tools starts with business connections

http://searchbusinessanalytics.techtarget.com/feature/Using-social-media-monitoring-tools-starts-with-business-connections An influx of social media monitoring and analytics tools -- many of them free and available as cloud-based services -- is making it easy for companies to get up and running with programs for analyzing social media data. But as with other analytics initiatives, doing so without a big-picture plan that's directly connected to an organization's core business goals will severely limit the technology's usefulness. To help head off potential business problems and drive more effective decision making in areas such as marketing and customer service, a social media analytics program has to do more than just capture and distill data from Facebook, Twitter and other online venues, according to a report on "social intelligence" published in August 2011 by market research company Gleanster LLC in Evanston, Ill.

Advocates of HS2 may feel somewhat vindicated. As far as data analysis is concerned, Twitter is primarily used for retrospective tracking of sentiment and other social data, but could geolocated Tweets be used to plan for the future? Data-mapping work by Eric Fischer suggests that it could.

Social media analytics startup Socialbakers raises $6M

http://gigaom.com/2012/11/19/social-media-analytics-startup-socialbakers-raises-6m/ As we saw this spring and summer, with the acquisition of Vitrue by Oracle , Buddy Media by Salesforce and Wildfire by Google , social media marketing is a hot space to be in. On Monday, social media analytics startup Socialbakers announced that it had raised $6 million in Series B funding, indicating yet more interest in the field. The Prague-based company said its latest round of funding was led by Index Ventures and included participation from existing funder Earlybird Venture Capital. It follows a $2 million Series A round announced last fall. Launched in 2009, Socialbakers works with brands, such as McDonald’s, Nestle and LVMH to measure the performance of their social media campaigns (and compare their progress against rivals) on Facebook, Twitter, YouTube, LinkedIn and Google+.

Nov. 11, 2012 — Although schizophrenia is highly genetic in origin, the genes involved in the disorder have been difficult to identify. In the past few years, researchers have implicated several genes, but it is unclear how they act to produce the disorder. A new study by researchers at Columbia University Medical Center identifies affected gene networks and provides insight into the molecular causes of the disease. The paper was published November 11 in the online edition of the journal Nature Neuroscience . Using an unbiased collection of hundreds of mutations associated with schizophrenia, the Columbia researchers applied a sophisticated computational approach to uncover hidden relationships among seemingly unrelated genes. http://www.sciencedaily.com/releases/2012/11/121111153933.htm

Understanding Learning Analytics and Student Data

There’s a lot to unpack about learning analytics — everything from how student data is captured to how it will be used . For all of its promises — and there are many, as evidenced below — the two biggest areas of concern regarding using student data are around issues of privacy, as in who has access to student information and what are the possible negative ways that information could be used, and how student data might be used against educators. Privacy is addressed in this otherwise mostly positive infographic, created by Australia’s informED , which takes a crack at explaining all the different aspects. What else would you add to it?

The Anatomy of a Search Engine

A Brief Introduction to Social Network Analysis by Orgnet, LLC

Social network analysis [SNA] is the mapping and measuring of relationships and flows between people, groups, organizations, computers, URLs, and other connected information/knowledge entities. The nodes in the network are the people and groups while the links show relationships or flows between the nodes. SNA provides both a visual and a mathematical analysis of human relationships. Management consultants use this methodology with their business clients and call it Organizational Network Analysis [ONA].

Deconstructing a Twitter spam attack

There has been a lot of discussion recently about the effect fake Twitter accounts have on brands trying to keep track of social media engagement. A recent tweet spam attack offers an instructive example. On the morning of October 1, the delegates attending the Strata Conference in London started to notice that a considerable number of spam tweets were being sent using the #strataconf hashtag. Using a tool developed by Bloom Agency , with data from DataSift , an analysis has been done that sheds light on the spam attack directed at the conference. The following diagram shows a snapshot of the Twitter conversation after a few tweets had been received containing the #strataconf hashtag.

How Learning Analytics Can Make Instructors More Effective in the Online Course

This is the first in a three-part series on learner analytics, cutting edge insight for the course instructor; how to assess student behaviours in an online course using the LMS data collection tools in order to provide more effective course design and instruction. Most course instructors strive to create a class where students are engaged with the content, appear eager to learn and participate. The indicators of student engagement in a face-to-face class are straightforward enough, attendance, participation in class discussions, and/or visits to the instructor during his or her office hours. Measuring student engagement in an online course is more complex. However with the current learning management systems [LMS] such as Moodle and Blackboard now in use in virtually all education institutions, there is a treasure trove of data on student behaviour. This data has the potential to tell a story about a student’s engagement, even predict student success within a course.
