The Blue Chip Expert service - is this the future of networking?

I have recently received multiple invitations to join a startup internet network called the Blue Chip Expert service. Eventually I was unable to resist and joined, too, to learn more about it. My first feelings are however mixed.
On one hand, it is true that internet networks like this one will significantly change Executive Search and recruitment industry one day. On the other hand, all these networks must go through one very delicate phase: they have to be very innovative in the way how they catch attraction, but in the same time they should retain their credibility.
The dilemma is simple: all of these networks strive to become the next "de-facto" standard in their particular market niche and, in addition, they have to do it faster than any competitor. But it is too easy to become too "innovative"!
I cannot help myself, but the Blue Chip Expert service looks like a pyramid-game and has a strong flavor of multi-level marketing. Myself I have received 10 invitations in just three days, but I am a happy guy, because some friends of mine receive 20 invitations every day, which is very annoying. This email storm certainly helped the service to build awareness of professionals without extensive marketing money, but even through it didn’t cost the company a penny, I am pretty sure that the price was already too high. It is not a good thing for any service to become labeled "spam marketing", and even more it is true for a service that should be based on trust.
I already formed my opinion. I actually thought a lot about future of recruiting, including how to optimally use (virtual) communities in this process. I am pretty sure that motivation of the virtual community should be more complex than just a simple MLM-like scheme, which the Blue Chip Expert system offers.

The Power of LinkedIn

I’ve just joined the fast growing Central European team of Capgemini. In my new role of Managing Consultant it will be my pleasure to develop offerings of this global IT services and business consultancy around the lines of Service Oriented Architecture.

In another place of this blog I am discussing the business model of social networks. Indeed, the model is flawed, as today’s applications motivate participants to grow their “trusted” networks indefinitely (last time today I’ve got an invitation saying “it is always beneficial to increase the size and scope of ones network…”). So, this conclusion is very true.

But of course, even if the business model is not right, it does not imply anything about practical usability of these applications. Actually, I can serve as a good example myself. After being a member of the LinkedIn network for just two months, I was approached by headhunters working for Cap. They found my profile at LinkedIn around the same time when another big IT company found me on this network, too. Then both these companies approached me directly and gave me the luxury of deciding between two good opportunities.

The lesson learned? Applications like social networks really work. Even before visionary projects like UPI happen (sorry, this is my child :-)), social networks are already turning the internet into a more structured place. By improving search in more and more special areas, the internet is gradually becoming a medium where you can find what you need.

So there is one symbolism for me. Since now, I have a new job. But in the same time, I have been shown that the world has changed.

Welcome to a networked world! It will be my pleasure to continue meeting you there.

Funny Profiles on Zoominfo

These days a lot of people try hard to work on improving search on the internet. Today’s wealth of internet content is so vast that any method that would help people to differentiate quality content from the ballast (that is overall flooding the net) would be extremely beneficial. Well, we already have one such a method – it is called PageRank. This method is based on the “universal popularity” of a particular site expressed by links that are pointing to it. In other words, PageRank grubs out the semantic information on popularity from the only available syntactic tool: web links. The PageRank algorithm is well proven and fine-tuned to the best possible extent. It is very hard to find any further improvement of it.

Context digging

OK, so where can we move from this point? There are just two ways forward:

  • to add some additional syntax piece to the internet (that would help make the content better searchable), or
  • try to work better with the existing unstructured content.

Zoominfo can serve as a typical application of the second approach. It tries to dig out the semantics information from the context of keywords and automatically builds user profiles from publicly available news resources. To do this, it attempts to uniquely identify a particular person by searching its name in the context of other keywords that are automatically identified as being relevant to this person. This is a very non-trivial thing to do, indeed!

The Reality Check

Let me share some examples with you. If we search Zoominfo for the most popular Czech singer Karel Gott, we find eight (!) different profiles. The good news is that all are sort of related to the singer; however, the bad news is that no one is really correct and seven of the eight actually don’t mention that this person is a singer! Where is the problem? In the attempt to differentiate possible namesakes the system actually splits information about one person to many different profiles. Of course, the balance is difficult to reach. On one hand, it is wise to suppose that if there is a lot of information about a particular person, part of it should be contributed to namesakes. On the other hand, it doesn’t hold always, particularly if the person is really popular.

From professor to journalist or landlord

However, this problem is even more general and is not limited to top celebrities only. For example prof. Vorisek, who is the Head of Department of Information Technologies at the Prague Economic University, has 4 different profiles. Only the profile No. 2 is sort of correct, but it is vastly incomplete, just quoting his name and school. We don’t even know his function and have no idea about his other activities. In addition, some of the profiles are pretty funny. My favorite one is the one that actually identifies Jiri as a sort of landlord of Zofin Palace. In reality, Zofin Palace is just the venue of a regular annual conference Jiri’s department is organizing.

The conclusion

I don’t think that people at Zoominfo don’t try hard. They certainly do. The problem is a more serious one: the task to process context of keywords exceeds capabilities of today’s technologies, even if we limit this task to search in a particular context only (e.g., search of names and positions, as Zoominfo does). The idea itself is not bad, but it is a too ambitious one. Generally speaking, the complexity of this task is close to the problem of an automatic text comprehension and translation. Zoominfo’s case just illustrates that we are not at this stage yet.

This is a very clear message that shouldn’t be overlooked. It is (yet) very hard and even contra productive to automatically work with unstructured information, even in very special scenarios. On the other hand the syntax approach (PageRank) works well; the problem however is that its mechanism is already “milked to death”.

The solution?

To get better search results, we will have to add some additional syntax to the web. We should do it smartly – we cannot expect too much work from users, but in the same time we should make this web extension a clear advantage for everybody who joins.

There are many applications already that tackle the internet search problem this way – social networks can serve as a good example; thanks to their growing popularity they are in fact turning a significant part of the internet to a structured form! Another interesting example is the Friend of a Friend (FOAF) project.

We will however try to formulate a more general approach based on Unique Personal Identificator (UPI). It is actually a nice paradox that Zoominfo (and not only it) would greatly benefit from such a system. On the other hand, if the internet had UPI, applications like Zoominfo would not be necessary at all...
