Mountains as states of affairs

Trying to make sense of the deep work of Jan Christoph Westerhoff about ontological categories, reality and everything, along with a slow but steady learning of Chinese language and ancient philosophy, leads you to consider as ontological primitive the states of affairs, instead of good old semantic web things and properties, the latter being derived artefacts of the former, not the other way round. Let's try to illustrate this as simply as possible.
Consider a mountain. On the semantic web you represent a mountain as an instance of owl:Thing or one of its specific subclasses such as schema:Mountain. You claim to have defined a non-ambiguous individual identified by a URI and described by an open set of property-value pairs, such as http://dbpedia.org/resource/Mount_Everest.

But in the view of the world proposed by both Westerhoff philosophy and the Chinese language (insofar as I understand them properly), the above are just abstractions derived from some state of affairs. The chinese 山(shān) we translate in English as mountain(s) is a sign associated with certain aspects of things, or states of the world. We have to be very cautious on terms here, and not take for granted that existence of "things" and "the world" are preconditions to the states of affairs we associate with the sign 山. In ancient Chinese culture where this sign first emerged about three thousands years ago, the world is not divided into things before we name them. Certain states of affairs, patterns we recognize again and again, lead us to associate a sign to them. 山 is just an abstract visual representation of those states of affairs presenting peaks rising upward, a main central one and another one of each side, slightly asymmetrical. A mountain is indeed generally mountains, bearing in mind "three" has to be understood as a shortcut for "many".

The difference between considering there are such things in the world as individual mountains and we just give them individual names and put them in a category, and considering mountains as states of affairs we associate using a common sign or name, might appear subtle or moot. But it is indeed a fundamental shift of our view of the world. States of affairs are not neat individuals defined by properties, they are not separated from each other, they have neither precise limits in space and time, nor definite components and properties. Of course we can try to agree and generally agree to disagree upon such limits and components, and argue forever on what is or is not a mountain in general or this mountain in particular. And we actually argue upon what is a human being, or a book, or a Web resource, or democracy ... This kind of argument is interestingly called in Chinese 是非 (shì fēi), literally meaning "being - not being", hence "right - wrong" and in common language dispute, argument. There is much food for thought in this word. Dispute arises when the language gets out of its original role of simply putting signs on state of affairs, going down to argue on what there is and is not behind signs, in other words, when the language mingles into ontology and meaning instead of sticking to what it's really made for - poetry.

I wish you to stay away from dispute, walk up and listen to the mountain songs.

Open GUID : anchoring hubjects

Jason Borro has announced yesterday his Open GUID initiative on the Linking Open Data forum. After a first day of open discussion, it appears that he has came with the right implementation of hubjects, and moreover with a great metaphor. Hubjects must be anchored in signs, bot human-readable and computer-readable. Here is what I come with this morning.

Everything is a Sign

That is, every thing is a sign. The first and main function of any language is to allow division of the world into "this" and "not this", based on some interpretation of data received from the world. Such an interpretation of data as signs is the basic form of semiosis, a process performed for quite a while by humans, and for many more ages by animals before them. It can now be performed by machines or information systems (roughly, computers connected to data acquisition devices). The aspects of this process can be defined as following.
  1. SALIENCE : Capacity to separate as meaningful (significant or salient) a certain data set from the continuous data flow we get from the world through our perceptive experience, be it direct through our biological senses, or indirect through one or more several levels of mediation : reading data gathered by instrumental devices, compilation of such data over time, texts interpreting those data.
  2. SIGNIFICATION : Capacity to consider the salient data set as a signifier conveying a particular meaning (signified), based on some characteristics such as spatial connectivity, permanence in time, regularity of patterns, similarity with other data sets previously interpreted and stored as signs, or anything the interpreter sees fit by its own rules and general view of the world. The core and essential meaning assigned is generally permanence, existence of a "thing" underlying the "sign". The thing is the signified associated to the signifier which is the data set.
  3. REPRESENTATION : Translate this sign/thing (both signifier and signified) into some proxy in a representation language allowing storage and retrieval for further use. Typical forms of representation include assignation of identifiers (symbols, icons, names, code numbers), description of the signified, and its connection to pre-existing ones through classification, typing, or any other kind of association or linking.
The above analysis can be set as the basis for a general semiosis framework applicable to natural languages (human or otherwise), formal languages used in our information systems, and scientific languages (theories in physics, biology). This framework, while keeping agnostic at the metaphysical level on the ontological status of things, will hopefully help to provide a solid theoretical foundation to the emerging semiosphere, the network of human knowledge and languages and information systems.

OntoGlyphs

Toronto, Canada - August 24, 2004 - In a style more reminiscent of cave paintings or the scratchings of ancient Egyptians, scientists at the Blueprint Initiative (Blueprint) research program, led by Dr. Christopher Hogue at Mount Sinai Hospital's Samuel Lunenfeld Research Institute, have created a new visual language called OntoGlyphs to help scientists quickly identify the biological attributes of molecules in general and particularly the ones found in the Biomolecular Interaction Network Database (BIND).

"One of the biggest challenges that researchers face is trying to identify the individual molecular needles in the myriad haystacks of biological data. That's why we focused on developing a visual, 'glyphic' language, one that would allow researchers to identify patterns or connections at a glance."
