TheWebMiner in French

Good day everyone, or should i say better bonjour, because along this week we have launched the french version of TheWebMiner.com.

It is a certitude that the need for data increases every day in every possible direction and we want to keep up with this trend. Although English is the language of the internet we want to reach also to other users from smaller environments that might need our services, and because French is the official language in 29 countries it seemed as an obvious choice.

So, from now on along with the English version and the Romanian, which is the base country of our company a third version is available to choose in the language menu from the upper right corner of  our site.

french

We hope you will enjoy your experience and will provide a good feedback on our expansion.

 

Data Cleaning

In case you are really into data mining maybe you have wondered what happens to data after is extracted: does it gets delivered the way it is or there is more?

The truth is that extraction is only one part of the process and it is followed by several others, including Data Cleaning, the subject of today’s article.

The necessity for such a process has always been present in scientific areas where misleading results can induce false conclusions and lead to failure of the initial purposes but the automation has occurred relatively recent, in the last two decades when the need for cleaning was imposed to a very large quantity of data.

For data to be considered of high quality it must fulfill a series of requirements such as:

  • Validity, which represents the degree of correspondence with the usual business constraints. This is relatively easy to ensure, having to set up specific indicators as Data-type constraints or Range constraints or Mandatory constraints.
  • Decleansing represents error detection and syntactically removal of them for better programming.
  • Accuracy: The degree of conformity of a measure to a standard or a true value; this also requires an external set of data for comparison.
  • Completeness: percentage to which all required measures are known.
  • Consistency: The degree to which a set of measures are equivalent in across systems.
  • Uniformity, which ensures that all the measurements have the same measurement units and some aspects of validation.

This research area has more to complete until all the challenges that optimization imposes will be fixed. Today, problems like Error correction and lose of information through it, or Maintenance of cleansed data still create serious issues, but the with the advance of Big Data and interest exertion from the big companies such as IBM or Oracle in this field we can be optimistic and say that we are on the right track .

Why emotions are important in marketing

I don’t know about you but i haven’t given very much thought of how do i feel the instance that i press the “share” button. I recently found out that i was ignoring a much more important part of online marketing than it seems, and i corrected myself, all because of emotions.

When it comes to what we feel, everything can be expressed as a sum of four basic emotions: happy, sad, afraid and angry, that combine themselves and form a variety of other feelings about which we may or we may not be aware. For better understanding of this we may look at Robert Plutchik’s famous “wheel of emotions” that shows just some of the well known emotional layers.

 

Studies have also revealed that the emotional state that “gets” the most of the likes is happiness, which is normal if we consider that  our first emotional action in life is to respond to our mother’s smile with a smile of our own. Obviously, joy and happiness are hard-wired into all of us, as discovered by the psychoanalyst Donald Winnicott. And because happiness almost never comes as a self sustainable feeling we can see that the top 10 emotions that people have when sharing something are made of positive ones, as studied by Fractl.

More than this Jonah Berger, professor of marketing at the University of Pennsylvania’s Wharton School and author of Contagious: Why Things Catch On, conducted a study from which  he found that an article was more likely to become viral the more positive it was.

 

Of course we shouldn’t neglect that there are also other feelings that may interact with our online behavior.  For instance sadness helps us connect and empathize by producing cortisol, known as the “stress hormone”; and oxytocin, a hormone that promotes connection and empathy. Further research revealed that when we are angry the hypothalamus makes us more stubborn and fear only makes us more desperate to find something or someone to cling on.

Considering all this information is easy to understand the high significance of emotions in marketing, especially when considering that an analysis of the IPA dataBANK, which contains 1,400 case studies of successful advertising campaigns where, campaigns with purely emotional content performed about twice as well (31% vs. 16%) as those with only rational content.

And this is why we can’t underestimate the importance of understanding the science of emotion in marketing!

 

How to use regex in Vim?

We often need to process big text files (larger than 100 mb) and we discovered that best text editor for this is Vim and gVim (windows version). Also a powerful mode to process text automatically is to use regular expressions (also called RegEx).

Using RegEx in Vim

Vim doesn’t support standard RegEx, but we built a tool that converts standard regex to Vim regex. This tool it’s available here: RegEx to Vim.

We hope that is useful for you.

Why do you need Facebook for your business?

This might be a relatively simple question but the complexity of the answer might surprise you!

First of all, if you have a business and you don’t have a Facebook page for it, well, i’m sorry to tell you that you might be among the last ones which doesn’t. Forgotten are the times when not everyone were on this social platform and now, user concentrate on adding everything, from everywhere to it; this includes businesses, places, currents, events, personalities and many other daily-life aspects, all with the purpose of simplifying our actions.

People tend to be skeptical about the success of a business page but what they fail to understand is that even a small page with a small audience can make a difference. A research shows that merely six percent of all Facebook pages have more than ten thousand likes and that is not a problem. If given time the popularity of a page will grow and more and more users will be interested in the information provided by you. Another reason why people tend to avoid having a social media page for their business is that because it’s hard to keep it updated all the time. Although constant posts will keep your fans happy there is not a direct correlation between the posting span and the growth of the page.

On the other side there are plenty of different reasons that your business needs Facebook. What it boils down to, though, is that this is a free opportunity to reach out to your audience in their preferred environment, improve your SEO rankings and visibility, and show off your business in a way that people can relate to. This being said we want to familiarize you with TheWebMiner Facebook page were we constantly post technical news, updates about our tool or tips for our field of activity.

Smartphones Are Taking Over

One of the most important events on consumer electronics takes place these days Barcelona. Of course that I refer to Mobile World Congress where the most exciting latest technologies are being revealed. Manufacturers have to keep up with the demands of the market in producing more reliable and cheaper devices for everyday use.

Smartphones have one of the leading roles in this congress as their demand has grown unexpectedly in the last years. By the end of 2013 more than two thirds of the mobile subscribers in US had such a device and it seems that in few years conventional mobile phones will be forgotten.

Although smartphone penetration is pretty interesting to follow, a more interesting remark derives from it: the amount of time that people use to browse the web from their smart devices has significantly grew also, and actually in US it has already exceeded  the web usage on computers. According to a survey conducted by nielsen.com the average American spends 34 hours per month using his mobile and almost 27 hours on his computer. In Europe, the gap between the two has grown even further, with almost 42 hours spent by the average UK user on his mobile versus 28 hours on computer. The average Italian spends 37 hours on his mobile monthly and only 18 on computer, and the list can go on.

Not only are consumers spending more time using their phones but it seems that they are unable to put them down, the number of times a user accesses his smartphone throughout a normal day having risen from 5.5 times at the beginning of 2013 to 9 times in December.

Having all this information we can only predict even a larger growth of usage popularized by friendly interfaces and useful applications until gadgets will have minimized the interaction with our old trustworthy computers.
