Database, Information and Knowledge (DIK)

July 28th, 2010

Have decided to swiftly read through a copy of Luciano Floridi’s Philosophy and Computing, which I have had borrowed out from the library for a while. It was published in 1999 and seems to be a precursor of the establishment of the Philosophy of Information.

One part I found particularly interesting, titled ‘Data, information and knowledge: an erotetic approach’, is a short subsection of the fourth chapter, ‘The digital domain: Infosphere, databases and hypertexts’.

Luciano Floridi’s Philosophy of Technology: Critical Reflections

July 27th, 2010

Collections of literature looking at Floridi’s work keep on coming. Firstly, Knowledge, Technology and Policy has a special issue titled “Luciano Floridi’s Philosophy of Technology: Critical Reflections”. Papers to feature can already be found online: http://www.springerlink.com/content/105285/?Content+Status=Accepted.

Also, the Journal of Experimental and Theoretical Artificial Intelligence apparently has a special issue coming out titled “Inforgs and the Infosphere: Themes from Luciano Floridi’s Philosophy of Artificial Intelligence”.

Information Theory for Philosophers

Just came across some nice posts at the blog ‘On Philosophy’:

‘Information’ also gets its own category in this blog.

The Paradox of Inference and the Non-Triviality of Analytic Information

July 19th, 2010

New paper in the Journal of Philosophical Logic with a new take on the Scandal of Deduction: The Paradox of Inference and the Non-Triviality of Analytic Information. Part of the abstract:

Hence, although analytically true sentences provide no empirical information about the state of the world, they convey analytic information, in the shape of constructions prescribing how to arrive at the truths in question.

Some more material on the matter:

Vlatko Vedral: Everything is information

July 12th, 2010

Was listening to the Sun, 11 Jul 10 edition of the BBC’s The Forum program, in which Physicist Vlatko Vedral was a participant. Decided to look at some of his stuff and found this: Vlatko Vedral: Everything is information

Here Vedral explains why he believes the fundamental stuff of the universe is information – and how he hopes that one day everything will be explained in this way.

He has recently published a book title Decoding Reality: The Universe as Quantum Information.

Looks interesting, but I should read my copy of Seth Lloyd’s Programming the Universe: A Quantum Computer Scientist Takes on the Cosmos before I get another book on the matter.

An Analysis of Informational Relevance

June 7th, 2010

Am currently working on a paper to be given at this years AAL conference. Tentative details:

Title: An Analysis of Informational Relevance

Abstract: In this presentation a logical definition and analysis of informational relevance is given. Relevance is taken to be agent-oriented/epistemic, where the relevance of a piece of information is determined in terms of how well it satisfies an agent’s request, how well it answers their question. Firstly, a general metric is outlined whereby the relevance of a statement is measured in terms of its truthlikeness measure. Secondly, a logic is given in which a relevance operator is defined and investigated. The erotetic foundation for this logic is Hintikka’s approach to analysing questions as requests for information in terms of epistemic modal logic, which is then combined with a logic of intention.

Any thoughts or suggestions are welcome.

The Logic of Being Misinformed

May 23rd, 2010

Have just uploaded a draft of a paper I am working on, titled ‘The Logic of Being Misinformed’, which can be downloaded here. Feedback welcome. Following is the abstract:

It is well established that the states of knowledge and belief have been captured using systems of modal logic. Referred to respectively as epistemic and doxastic modal logics, they have been studied extensively in the literature. In a relatively recent paper entitled ‘The Logic Of Being Informed’, Luciano Floridi does the same for the state of being informed, giving a logic of being informed also based on modal logic. In this information logic (IL), the statement Iap stands for ‘a is informed that p‘ or ‘a holds the information that p‘. After a review of Floridi’s logic of being informed, including an explication of the central concept of semantic information, I go on to develop a complementary logic of being misinformed, which formally captures the relation `a is misinformed that p‘.

Information, Knowledge and Belief

May 14th, 2010

Just came across, somewhat surprisingly, this paper: Information, Knowledge and Belief. It investigates the relationship between information, knowledge and belief via modal logic. What’s more, it was written all the way back in 2000.

A Question Concerning Data

May 14th, 2010

The rejection of dataless information in accordance with the General Definition of Information leads to the following modest thesis of ontological neutrality:


There can be no information without data representation.

This thesis can be, and often is, interpreted materialistically, with the equation of representation and physical implementation leading to the following:


There can be no data representation without physical implementation.

which leads to


There can be no information without physical implementation.

This is the view of Landauer. A related discussion of the matter can be found here.
