Keeping with tradition

Yup - it's that time of the year again. Another year is almost done. For many of us at Paterva, 2014 was a really really tough year. But this post is not about us - it's about you. No well.. not really. It's about this time of the year and our special discount we run for a few days.

It's the time when your extended family comes to visit with their 17 snotty nosed kids, the time when your weird uncle pitches up unannounced wearing only underpants and when your wife/husband/girlfriend/boyfriend/dog/cat/budgie/parrot is as stressed-out as you are. Perhaps us IT people are not *really* that much of herd animals after all.

This is why we run the Maltego Christmas special every year. This year we're giving 44% discount on licenses - from today up to the end of the 25th. It will allow you to retreat back to your computer during these days and make pretty graphs. When someone calls you for another family photo you can show them the graph (we suggest full screen mode) and s…

Tweet Sentiment Analysis

Hey there,

It’s been a while since we last posted but we are pretty excited about our new sentiment analysis transforms so I thought I would make a quick post about it.

Sentiment analysis can be described as the use of natural language processing (NLP) to extract the attitude/opinion of a writer towards a specific topic. With the overwhelming amount of data being posted on the Internet every day and no way to read it all, sentiment analysis has become a really useful tool for extracting and aggregating opinions on a specific topic from many different sources. The potential use for sentiment analysis is endless, a few examples are things like brand reputation monitoring, market research, stock-exchange monitoring, etc. The transform that we built takes a Tweet as its input entity and returns either positive, neutral or negative entity. This way a large amount of Tweets can easily be categorized according to their sentiment.

Although sentiment extraction is a relatively new area of r…

reCaptcha: Stop spam...and everyone else.

Hey guys,

About a week ago we noticed that the images we were getting from reCaptcha were near impossible to solve. And wow did people let us know, we've had emails ranging from just strings of cuss words to people who refuse to touch anything we do after it.

Unfortunately as we were just passing on an image we got from the google reCaptcha service ( )  it wasn't really in our control. We have seen them go through bouts of absolute madness, but usually only for a day or so. We decided to leave it for a week and hoped it would get better. It sadly didn't.

At this stage we are no longer verifying reCaptcha images (you can put in anything and it will validate) while we explore other options.

We apologise for the inconvenience, frustration and mental instability trying to solve those impossible CAPTCHAs were.

Monkeys gone to heaven.
