French Startup Sépage Says the Future of the Web is Semantic - Semanticweb.com | dataInnovation | Scoop.it
Fàtima Galan's insight:

"Websites like Amazon already have recommendatory systems based on statistics (‘Users who bought this also bought…’). This type of approach works, but has the disadvantage of providing converging recommendations. For instance, if you buy a Star Wars DVD, the recommendations will probably be Star Wars Episode two and three. Now, with a semantic recommendation approach, the algorithm would search the graphs and find out, for instance, that Star Wars was inspired by Isaac Asimov’s Foundation books, or other similar science fiction movies. Much more inspiring. And inspiration can be very valuable.”"

Evaluating sentiment in financial news articles

Evaluating sentiment in financial news articles | dataInnovation | Scoop.it

Can the choice of words and tone used by the authors of financial news articles correlate to measurable stock price movements? If so, can the magnitude of price movement be predicted using these same variables? We investigate these questions using the Arizona Financial Text (AZFinText) system, a financial news article prediction system, and pair it with a sentiment analysis tool. Through our analysis, we found that subjective news articles were easier to predict in price direction (59.0% versus 50.0% of chance alone) and using a simple trading engine, subjective articles garnered a 3.30% return. Looking further into the role of author tone in financial news articles, we found that articles with a negative sentiment were easiest to predict in price direction (50.9% versus 50.0% of chance alone) and a 3.04% trading return. Investigating negative sentiment further, we found that our system was able to predict price decreases in articles of a positive sentiment 53.5% of the time, and price increases in articles of a negative sentiment 52.4% of the time. We believe that perhaps this result can be attributable to market traders behaving in a contrarian manner, e.g., see good news, sell; see bad news, buy.

Luca Naso's curator insight, June 13, 5:11 AM

Big Data can be extremely dangerous without a Big Brain to analyse them properly.


Huge data sets ALWAYS contain some relations: some of them are right (causation), others are simply wrong. It pertains to data analysis to uncover the truth.

 

"As we move into an era in which personal devices are seen as proxies for public needs, we run the risk that already existing inequities will be further entrenched.

[...]

This goes beyond merely conducting focus groups to confirm what you already want to see in a big data set. It means complementing data sources with rigorous qualitative research."

The above examples describe a wide range of geographical and geotemporal storytelling models, often based around quite simple data files containing information about individual events. Many of the tools make a strong use of image files as pat of the display. it may be interesting to complete a more detailed review that describes the exact data models used by each of the techniques, with a view to identifying a generic data model that could be used by each of the different models, or transformed into the distinct data representations supported by each of the separate tools.

Who Needs Open Data for the Extractive Industries? | Natural Resource Governance Institute

Fàtima Galan's insight:

"Efforts like the Extractive Industries Transparency Initiative, and more recently disclosure legislation in the US and EU, have increasingly made it a part of "responsible business" for companies and governments to be open and transparent about their financial dealings in oil, gas and mining. However, revealing payment data alone achieves little, especially when it has been locked up in PDFs, or aggregated and anonymized. It runs the risk of further limitations if unaccompanied by openness about the deals that have been signed. Governments and citizens alike need to know what happens to the money after it reaches the country's treasury. Following the money is becoming an important concern in resource-rich countries, to ensure that money from oil, gas and mining is transformed into increased revenues for the government, into open and effective budgeting, and ultimately into sustainable development that benefits all citizens."

Analyzing big data is now an important part of business operations, and it requires significant time and resources to better understand and apply the solutions that big data offers. One developing technology that is greatly simplifying this process is virtualization, specifically data virtualization, which is allowing businesses in increase their value while turning big data analytics into an important enterprise tool.

What is ‘open development’?


Open Development sits at the intersection of the ‘open’ movement, and international development. This could take the form of looking at how open data can affect decisions made within international development; open access to research materials; or opening up the ways we work, for example by being more inclusive, to name just a few examples. If you want to find out more about open development, join the Open Development mailing list, where a wide range of topics within Open Development are discussed. It’s open to everyone to join!

Les différences culturelles sont la source de nombreux malentendus dans un cadre professionnel international et multiculturel. Erin Meyer, professeure de management interculturel à l’INSEAD (Fontainebleau), a développé un outil pour visualiser ces malentedus qui peuvent survenir entre des équipes de deux pays différents. La Harvard Business Review publie une version interactive de ces comparaisons internationales.

BY ERIN MEYER. To help managers negotiate this complexity I have developed a tool called the Culture Map. It plots culture on eight scales that apply to the most common challenges managers face. By comparing the relative position of one culture to another on each scale, a manager can decode how culture influences day-to-day collaboration. Try the pairs illustrated in this exhibit to see how the map can help. Many other culture pairs are available in my new book The Culture Map.
