Social Sentiment Analysis: David Ferrer v Juan Martin Del Potro. Brought to you by Wimbledon Insights

We hoped for some drama, but nothing prepared tennis fans for the thrills and spills of the match between the No.4 seed, David Ferrer, and the No.8 seed, Juan Martin Del Potro. Del Potro not only came back from what looked like a match-ending injury, but went on to win the match in a heroic performance.

IBM’s social sentiment analytics track how players are being perceived on Twitter throughout the match, watching not just the number of their tweets but their content, using sophisticated tools to decide what percentage is positive or negative. Ferrer began the match with a positive sentiment score of 83%, with Del Potro trailing at 79%. Then disaster struck. Del Potro fell badly in the very first game, aggravating an existing knee injury.

For a moment, it looked like the Argentinian would be unable to continue. “Can’t believe Del Potro has fallen in the first game. This was destined to be a five set thriller with him and Ferrer” tweeted @MattGriffen. Then Del Potro got up and continued the match. “Gotta feel for Del Potro. Brave man to carry on” posted @DanITFC. As Del Potro played on despite obvious pain, the tweets poured in, with over 1500 in a ten minute period. “Del Potro is a Legend, playing the match with an injured knee. Respect to him” said @MitchelJason95. “Unbelievable effort from Del Potro on Centre Court. I’d adore it if he managed to pull through” tweeted @haris_haseeb.

In fact, as the first set continued, Del Potro looked like he could not merely carry on, but actually take the set. “Del Potro is unbelievable. The guy is basically on one leg and is bossing this match!” tweeted @NotFredRhodes. As Del Potro claimed the first set, over 1600 tweets poured in during ten minutes, with 1500 also mentioning Ferrer. “People ask why I like Del Potro so much. I think from today’s performance, we can see why” posted @scott_grimes12.

The excitement continued in the second set, as Del Potro maintained his 79% social sentiment score, while Ferrer’s slipped slightly to 82%. “Dell Potro breaks! Serving for the second! He might actually do this!” tweeted @willdavenport1. “This is the best performance out of anyone in the men’s singles so far this Wimbledon. Brilliant from Del Potro” posted @aidan_duguid95. As Del Potro closed the second set 6-4, over 2000 tweets were posted in ten minutes.

Ferrer fought hard to stay in the third set, taking it to a tie-breaker, but Del Potro finished the set on top to end the match 6-2, 6-4, 7-6. Twitter didn’t reach the same level of fever-pitch as in the first two sets, but the praise kept flooding in. “Okay, fair play, Del Potro. That was incredible” posted @plkunnussijaa. “Del Potro through to the semis. Straight sets win against Ferrer, carrying an injury early on. Wonderful to watch” added @Rketts21.

For the first time in my life I have a sworn enemy – and I don’t even know her name

The cyclist, though, was enraged. “THAT’S CLEVER, ISN’T IT?” she yelled. “WALKING IN THE ROAD!”

Last month, I made an enemy. I do not say this lightly, and I certainly don’t say it with pride, as a more aggressive male might. Throughout my life I have avoided confrontation with a scrupulousness that an unkind observer would call out-and-out cowardice. A waiter could bring the wrong order, cold and crawling with maggots, and in response to “How is everything?” I’d still manage a grin and a “lovely, thanks”.

On the Underground, I’m so wary of being a bad citizen that I often give up my seat to people who aren’t pregnant, aren’t significantly older than me, and in some cases are far better equipped to stand than I am. If there’s one thing I am not, it’s any sort of provocateur. And yet now this: a feud.

And I don’t even know my enemy’s name.

She was on a bike when I accidentally entered her life. I was pushing a buggy and I wandered – rashly, in her view – into her path. There’s little doubt that I was to blame: walking on the road while in charge of a minor is not something encouraged by the Highway Code. In my defence, it was a quiet, suburban street; the cyclist was the only vehicle of any kind; and I was half a street’s length away from physically colliding with her. It was the misjudgment of a sleep-deprived parent rather than an act of malice.

The cyclist, though, was enraged. “THAT’S CLEVER, ISN’T IT?” she yelled. “WALKING IN THE ROAD!”

I was stung by what someone on The Apprentice might refer to as her negative feedback, and walked on with a redoubled sense of the parental inadequacy that is my default state even at the best of times.

A sad little incident, but a one-off, you would think. Only a week later, though, I was walking in a different part of town, this time without the toddler and engrossed in my phone. Again, I accept my culpability in crossing the road without paying due attention; again, I have to point out that it was only a “close shave” in the sense that meteorites are sometimes reported to have “narrowly missed crashing into the Earth” by 50,000 miles. It might have merited, at worst, a reproving ting of the bell. Instead came a familiar voice. “IT’S YOU AGAIN!” she yelled, wrathfully.

This time the shock brought a retort out of me, probably the harshest thing I have ever shouted at a stranger: “WHY ARE YOU SO UNPLEASANT?”

None of this is X-rated stuff, but it adds up to what I can only call a vendetta – something I never expected to pick up on the way to Waitrose. So I am writing this, as much as anything, in the spirit of rapprochement. I really believe that our third meeting, whenever it comes, can be a much happier affair. People can change. Who knows: maybe I’ll even be walking on the pavement
