En Internet nadie sabe que soy un perro.

A principios de la Web, allá por el año 1993, se hizo famosa una viñeta del dibujante de la revista The New Yorker, Peter Steiner. Un perro delante de un ordenador, le dice a otro: “En Internet, nadie sabe que eres un perro”, en clara referencia al anonimato que existía entonces en la Red. Dos décadas más tarde, el cómic apenas tiene sentido.

Hoy, el rastro digital que dejamos en la navegación de la Web — captado por las cookies–, o en las apps de redes sociales, nos hace a todos, sin excepción, visibles…

Hoy, con la crisis mundial del corona virus, la conectividad a Internet aparece como un factor crítico para la vida personal y social, pues permite acceder a apoyos que disminuyen los riesgos de contagio. También, permite disminuir la distancia social cuando debes mantener una separación física (“distanciamiento físico” [1]) con el resto del mundo. …

Encuéntrame, descárgame y úsame. Déjate luego seducir y vuelve a mí una y otra vez. Yo por mi parte usaré mucho, mucho sentido común y trataré de sorprenderte cada día.

La Web es a la vez un mundo de sorpresas y desilusiones, es como navegar en un mar lleno de basura, contaminado, encontrando sólo a veces corales y perlas. En este artículo abordamos el problema de las premisas básicas para diseñar buenos sitios Web. Según Jakob Nielsen [ Nielsen 1999]…


The words “big data” tend to conjure up an image of a flowing fountain of information worth its weight in gold, and in many ways, that’s a fair interpretation. Big data, when applied correctly and efficiently, can provide immeasurable insight into the behaviors of people. However, with respect to IoT, data is far bigger. Indeed, Gartner forecasts that 14.2 billion connected things will be in use by the end of 2019, reaching 25 billion by 2021. But it boils down to more than just the number of things; it’s also about how they operate.

To illustrate my point, imagine the…


If we were to stare at a timeline chronicling the evolution of search, we could look into the past and see how it began with simple keyword recognition. Closer to the center, in the present day, we see how natural language processing (NLP) and machine learning help us recognize and predict user intent, finely tuning results to provide more accurate answers. But as we turn our heads toward the future, it is conversational search that will likely become the norm.

With 55% of U.S. households expected to own a smart speaker by 2022 , conversational search represents an obvious and…


From small mom-and-pop shops to multi-million-dollar corporations, all businesses face similar challenges when it comes to building a brand, increasing consumer engagement and gaining a competitive edge. Technological advancement has historically aided in this effort. For example, thanks to computers and the Web, online shopping has become a convenient way for many brands to reach new customers, expand geographical reach and broaden their product line. However, one could argue it has led to the death of brick and mortar stores, yielding thousands of employee cuts and profit losses from customers who prefer traditional “try and buy” methods of shopping.

What Is It, How Does It Work and Why You Should Care?

One of the most exciting things about first dates is the chance to get to know someone. With most people attached to their smartphones, it’s getting harder to meet people in a traditional setting. For years now, dating apps have been using algorithms to help people find love, but what if finding love meant divulging deeply personal details … to a chatbot ?

That’s exactly what a group of young adults are doing in Japan to help break the ice in social settings and find a desirable match. …


Which is the proper focus?

We find ourselves in the era of big data, where vast, continuous streams of heterogeneous human-related data are collected by digital means, and simplified for consumption according to the 5V characterization: Volume (size of the data), Variety (diversity of the content), Velocity (the rate it’s produced), Veracity (the quality of the content) and Value (it’s business impact). These humongous data sets are collected via many different means including computer networks, social media profiles, web browsing histories, mobile phone sensors, Internet of Things (IoT) devices, video data from (self-)driving and robotic applications, our commercial transactions and more.

For most businesses, having…
