Group items tagged

Andreas Hotho's talk more specifically addressed the search for methods to identify tags which describe the same concept (or a more specific / a more general concept respectively) within a folksonomy. He suggested two approaches: 1. Applying measures directly to folksonomy statistics, allowing to describe tags as a vector; e.g. co-occurrence frequency and FolkRank could serve as a similarity measure (with these two having a tendency towards high-frequency tags) or a cosine method (which is more likely to produce "siblings") 2. Looking up tags in an external thesaurus/vocabulary (for instance achieving semantic grounding by mapping a tag and its most similar tags with Wordnet Synsets)

Global (e.g. organization-wide) patterns emerge from everyday 'local' (i.e. one-to-one or small-group) conversations. The more that people (in interaction) make sense of events and take action in particular ways, the more likely they are to make similar sense and take similar actions in the future. That is, from an informal coalitions perspective, these patterns are not formed by managerial dictat or design but by the nature of the everyday sensemaking that has gone before.

While I understand the principles behind AntStorm's voting system for regulatory purposes, I wondered if it would be more useful for voting to occur from any user after the fact, similar to StumbleUpon or Reddit. My main concern about the voting system was that it would require too much time on the part of the group members, who would need to vote for every single item submitted to a group. To this concern, Wilson explained that the AntStorm voting system is designed to work effectively without participation from all group members, and Wilson's hope for AntStorm is to have such dedicated group members that will have only a handful of interest groups, enabling them to readily devote time towards those topics which are of greatest importance to them.

For the past few months I've been an active member of Twine.com; a beta semantic web app riddled with AI to help us organize, share and discover information. The beta is still under heavy construction, but at this point in time, I've migrated entirely from Del.icio.us, personal wikis and similar online services and over to Twine.

OntoWiki facilitates the visual presentation of a knowledge base as an information map, with different views on instance data. It enables intuitive authoring of semantic content, with an inline editing mode for editing RDF content, similar to WYSIWIG for text documents.

Yesterday, together with my colleague Ricardo Sueiras of PwC UK, we had a demo of Connectbeam the entreprise social bookmarking appliance. Connectbeam is an enterprise social networking tool using shared bookmarks and tags as a way to connect people. Basically it connects people who use the same content, on the grounds that it is likely that they have similar activities or interests, and will benefit from knowing each other.

A twine about the concept of an emerging global brain. What are the similarities and differences between the Internet and the human brain and nervous system? What are the steps that are leading us towards a global brain? What are the implications of the global brain?

Drug Ontology is developed by the nosology project at Stanford Center for Biomedical Informatics Research. This project seeks to discover new therapeutic uses and adverse effects of drugs by finding diseases that have gene expression profiles similar to those of the known indications and adverse effects of drugs. The objectives of the Drug Ontology are: * defines a core set of concepts and relationships that allow us to integrate information from multiple sources, * provides classification services along multiple axes, * provides links to external sources so that data not in the ontology can be queried from these sources.

MyThreads-Links is a flexible web based links manager that looks similar to Yahoo but was written in PHP and uses MySQL. MyThreads-Links uses PHPLib Templates so that its very simple for anyone to change the look and feel of the program without having to edit the code.

R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R.

"URIs, a universal identification scheme, are different from human names insofar as they can provide the ability to reliably access the thing identified. URIs also can function to reference a non-accessible thing in a similar manner to how names function in natural language. There are two distinctly different relationships between names and things: access and reference. To confuse the two relations leads to underlying problems with Web architecture. Reference is by nature ambiguous in any language. So any attempts by Web architecture to make reference completely unambiguous will fail on the Web. Despite popular belief otherwise, making further ontological distinctions often leads to more ambiguity, not less. Contrary to appeals to Kripke for some sort of eternal and unique identification, reference on the Web uses descriptions and therefore there is no unambiguous resolution of reference. On the Web, what is needed is not just a simple redirection, but a uniform and logically consistent manner of associating descriptions with URIs that can be done in a number of practical ways that should be made consistent. "

A great review of the challenges that follow from using URIs for both access and reference
