Public note-taking: some things about networks

It’s been hard to find time to write about anything nowadays…

Today I’m using the blog truly as a way of organizing my thoughts. I am having a bit of a hassle to organize my notes about networks and the spread of information. There are a couple of dimensions to cover. First, the technical aspects starting with graphs and their evolution to the modern manifestations of small-world networks and its subsequent variations such as — if I am correct — scale-free networks, including their inner structure, the connectedness of their nodes, their order and randomness and other technicalities.

Secondly, when specifically talking about social networks, there are issues such as the actors within them and the roles they play such as hubs and authorities, as well as the so-called “influentials” and their apparently marginal advantage in comparison to “normal” nodes in their capacity to spread information more efficiently (cf. Watts). One must not oversee the functions of strong and weak ties (cf. Granovetter), the former being part of tightly knit clusters formed of intimate connections and the latter functioning as bridges between different clusters on a network. Weak ties, according to Granovetter’s highly influential theory (1973), play an important role as bridges between different communities. Other social roles must be also taken in consideration, such as those of opinion leaders (Katz, Lazarsfeld 1955), innovators and early adopters in the diffusion of innovations (Rogers 2003) and more popular incarnations of “influentials” like those described by Gladwell (2000), among others.

Thirdly, with the social roles accounted for, we must, or I must :-), consider the spread of information and the dissemination of knowledge across networks, taking in considerations the several concepts and models that have been established in the analysis of social networks and in the “new” science of networks (Watts 2004). There are theories such as the SIR model (Susceptible, Infected, Recovered) which look at the spread of information from an epidemiological perspective with variants that take in consideration the “resistance” of nodes to contagion (thresholds). Other approaches include information cascades, percolation theories, the diffusion of innovation model of Rogers, among others. But their all share a similar aspect, that nodes can in way influence each other, depending on their ability to convince their neighborhood and the latter’s resistance these ideas, and also how connected nodes are to one another. If nodes are too tightly connected, cascades stay local, if they are too loosely connected to random parts of the networks cascades may disperse; there should be a compromise between looseness and density. Virtue lies in the mean as our good friend Aristotle would already say back in the day.

Anyway, this post has got much bigger than I expected. It however helped me in putting a mess to my thoughts. I’m starting to appreciate this blog thing… that is, if one is able to find the time to do it

Knowledge only grows when its communicated

I’ve been researching for the past weeks whether knowledge is able to grow within social contexts. Throughout the literature that I came across, there is a stark distinction between scientific and non-scientific knowledge. Philosophers of science such as Popper don’t even consider the product of the “episteme” to be knowledge at all, and it has mainly to do with the question of truth. That’s a difficult and controversial topic, but for the purpose of my research I assume that any form of knowledge, scientific or not, must be assumed to bear, at least in social contexts, a shared agreement as to what it is to be “true”. I will no longer differentiate scientific and non-scientific knowledge, and will call it just knowledge.

So, assuming that knowledge to be called as such must be true, is it possible to maintain, and to measure, that it can grow, even if it can’t be fully objectified? Let’s consider for example culture, which I consider to be a subset of knowledge. Almost everything we do is somehow strongly influenced by culture, our surroundings, our previous knowledge of objects and concepts, in other words, our “operational” knowledge, which shapes our actions and tastes. As I am writing this, I am drawing concepts from past memories, working within a set of rules of communication (the blogosphere) and expecting a certain  way understanding from the part of eventual readers, a shared culture if you will. The very text you are reading is a product of combination of external and internal knowledge and that has gone to a certain cognitive work-through, grounded on mental and cultural processes. Some readers might use some of the ideas found on this text, combine with others and with their own and create other texts, contributing to an chain of narratives that will eventually demarcate the boundaries of one specific subculture.

The growth of this knowledge is almost impossible to objectify. Therefore we must resort to other means such as the understanding of the communication technology with which this knowledge is produced and communicated to attempt to quantify it. Since the internet is inherently “measurable”, with log files, backlinks, trackbacks as well as with other data about the dissemination of information being largely available, at least potentially, we have means to understand this growth. One way is to look at the social structure in which this knowledge exists and try to understand the dynamics and informational flows of this environment. Another is to look at how content is transformed through time, that is, how progress and eventual setbacks happen along the communicative way of knowledge. One thing is tantamount to the growth of knowledge as much as it is a platitude: knowledge only grows when its communicated.

When concepts are put into words, in order to be understood they must be phrased within common language and be meaningful to the participants involved in the communication activity. This is what Habermas calls universal pragmatics, in which he sets forth a set of “validity claims” in order for communication to be productive. So when words, sounds and images are out there, we’re inevitably — as long as we are meaningful — contributing to the growth of knowledge as long as there is at least one receiver of the message. What this receiver ultimately does with message will only contribute to the social aggregate of knowledge as long as its also subsequently communicated.

Naturally, this must be quantified in some manner. Alvin Goldman, a philosopher studying social epistemology, calls these gains in knowledge Veritistic Gains or simply “v-gains”. In order to achieve a higher v-gain, participants with low knowledge must communicate or interact with participants that have a higher knowledge of a specific topic. The highest v-gain possible is when a inquiry is “fully” answered and one moves from a state of non-belief (no knowledge) to full belief (high knowledge). Here we coming back to question of truth again, but as aforementioned I regard knowledge as being true with a certain agreed context (relativism can be discussed later) and moving from no knowledge to high knowledge is no small feat, and it largely relies on communication.

Blogging as a way of organizing your thoughts…

Kind of continuing on the previous post about the creation of new knowledge. Lilia Efimova has wrote some interesting papers on the nature of blogging and it’s relation to knowledge. Although writing from the perspective of knowledge management within organizations, she establishes interesting concepts in which blogging may be useful in one’s stride to organize his or her knowledge. One may use a blog as personal content management system, I certainly have been doing that. Sometimes posts might not even be published, but just the fact that you must put them into readable thoughts, may help you in structuring your ideas for future access.

We can also use this space to create a conversation, which is a way of maintaining knowledge alive for a period of time — as long as the conversation is going on — and a way of polishing your arguments, which in itself may not be considered new knowledge, but as refinements of existing thoughts. You can gain however insights from comments and conversation, assuming that you amass the right audience for your topics. I personally am new to blogging, just about over a month, and the more I write it, it seems, at least, the more comfortable I feel about it. This is also another topic covered in one of her papers. Later I will certainly come back to them in more detail.

If you are interested in insightful research on blogs, here are some of Efimova’s papers on the topic.

Does sharing knowledge create new knowledge?

Does the Web 2.0 actually increase the stock of knowledge held by those with access to it, or does it maintain the existing level and merely transmits it? Me and my Thesis supervisor, Prof. Paolo Paolini at the University of Lugano, haven’t really arrived yet at any conclusion. I set out to a little investigation on the epistemology of Web 2.0, I found of some papers, not specifically on the topic, but mainly in relation to the creation of new knowledge with the help of new technologies.

Without yet so much theoretical support I risk to say that, perhaps, the increase of knowledge comes through the otherwise non existing connections of different knowledge pools, in other words, through the interconnection of different disciplines, which is made nowadays much easier with the use social technologies, and an exponential augmentation of serendipitous knowledge finding methods, leading to new “open doors”. Today I read Lyotard’sThe Postmodern Condition: A Report on Knowledge“, which has thoughtful and acute insights in this direction. Although written in 1979, some of his predictions were actually spot on, especially related to explosion of “computerization” and the almost ubiquitous access to an overall knowledge “data bank.” It’s cute how old folks talk about technology. :-)

What he has not predicted was that those that would have access to this knowledge would also be able to alter it, mash it, remix it and give their interpretation on it. And also the speed in which information goes through “nodes” (us) today does probably affect the way in which we are able to acquire this knowledge, it is probably more than ever just in a transient state. We might not even acquire it, we are just permeated ad-hoc by it upon need. There is much more to his arguments of course, and it is not about technology, it’s about how people have lost their belief in a grand metanarrative or ideologies, and how this leads into new ways for the legitimation of knowledge. Anyway, it’s a thin — I mean in the number of pages — and thought-provoking read.

Anyway, going back to the beginning question of this post… anybody there knows it?
