"Whether you realize it or not, you're already familiar with controlled vocabularies. The Library of Congress subject headings and Yahoo's search criteria are a couple of examples. So, as you've probably guessed by now, controlled vocabularies are predete
At heart, a blog is just a database...But most blogs only divide up the information by time...for a reader, it's probably the least interesting way of reading. I've turned Ishbadiddle into a semantic web...categorized, coded, 1,385 keywords...
Discussion of flaws and potential solutions to using social bookmarking sites (from del.icio.us to digg) as folks monetize, abuse, trick, and tweak them: no uniform tagging conventions, flat tag structures (non-relational), overly-generalized tags (catego
OntoSelect monitors the web to provide an access point for ontologies on any possible topic or domain that is automatically updated, organized in a meaningful way and with support for ontology search and selection. Selected ontologies may be used for ins
I’m seeking ways to expand metadata hooks into new areas of my overall information management scheme...[excerpt from] tecosystems...because technology is just another ecosystem.
Ex: When viewing http://www.bibsonomy.org/user/schmitz/linux, you will be offered the possibility of seeing the tag linux as a concept. That way, you will also see those resources not tagged with linux themselves, but with a direct subtag thereof, for exa
Tag Descriptions allow you to describe your tags for yourself and others visiting your bookmarks...simply go to your tag page. From this page you should see a link called "create tag description". Clicking this link pops up the interface for creating a Ta
Annotea is a W3C Semantic Web Advanced Development project that provides a framework for rich communication about Web pages through shared RDF metadata. An RDF model of bookmark classification permits multiple classification systems to be related to each
After analyzing a large amount of social annotations, we found that tags are usually semantically related to each other if they are used to tag the same or related resources for many times. Users may have similar interests if their annotations share many
It might seem redundant to have semantic tagging when you can basically find anything you can think of with simple searches in Google or Yahoo. But del.icio.us seems to be most surprising when you're trying to find things that relate to what you're intere
Automatic semantic annotation of information content is an open problem, but is crucial to the realization of the Semantic Web. Annotation systems require the initial definition of an ontology and as well as a knowledge base. Both of these resources work
This column, the third in a series, shows how to add semantic knowledge to an RDF application by incorporating WordNet synonym sets. With the added knowledge of the WordNet lexical database, you can search a set of RDF data for related concepts, not just
Part of the allure of classifying things by assigning tags to them is that the user can give free reign to sloppiness. There is no authority —human or computational— passing judgment on the appropriateness or validity of tags, because tags have to mak
The goal of this ontology is to model the relationship between an agent, an arbitrary resource, and one or more tags. This relationship is embodied in one or more taggings, which are temporal events associating the actors.
Yesterday, I had dinner with two people from yet another startup that uses tagging and collaborative filtering in the same sentence. So are tags and collaborative filtering a marriage made in heaven? It's a promising approach, but there are challenges in
Let's explore how the lower cognitive cost of tagging makes it popular...From my first encounter with tagging (on systems such as del.icio.us & flickr), I could feel how easy it was to tag. But it took me a while to understand the cognitive processes at w
Del.icio.us tags aren’t like meta keyword tags because of the Del.icio.us Lesson. Meta keyword tags provide no personal value whatsoever. All of their value is social. They’re for aggregation engines to find and tell other people about. In other words
MusicBrainz is a community music metadatabase that attempts to create a comprehensive music encyclopedia. You can use Musicbrainz right now to automatically identify and label your music files — all you have to do is download and run a MusicBrainz enab
MusicBrainz is a user-maintained community music metadatabase...artist names, release titles, tracklist...Its web site is the interface which allows the creation and maintenance of the data, all user-contributed and user-maintained.
We need solutions that can help the many people whose terms and vocabulary are left out of the taxonomy... The simple idea that people’s actions model meaning better than a directory (even a flexible directory) is a critical step forward in thinking ab
Is there a true need, an actual problem to solve, that would justify creating a "tagcloud microformat?" This author believes so, and details exactly why (and how) based on a survey of tagcloud models on existing sites.
Real life data needs are never semantically pure. Users need to browse their data in different ways. Hierarchies are too hard to reorganize on a whim. Stuff I need access to DOES NOT HAPPEN TO EQUAL the stuff at the top of the tree: Hierarchies are bad a
I’m a bit of a Saussurean about this, in that I think that taxonomy (or ontology, depending upon your disciplinary point of origin) is crystallised/calcified folksonomy....Crystallised and calcified...one has connotations of order, beauty, and value; th
You can tag arbitrary content on the web, you can do it in a low-tech way to make it easy for everyone to do...But...How do you find instances that people haven't tagged? Or deal with overlapping meme labels?
A memespace has a unique alphanumeric identifier to disambiguate it from other memespaces. The present design for meme IDs is: MEMESPACE-TAXOSPACE-ID. Essentially, it's another controlled vocabulary...
Memography is our name for a simple syntax for tagging that affords high precision and recall when searching & retrieving the web pages you've tagged (mimetic search)...
extisp.icio.us images displays a random Yahoo images search result for each of a user's tag words (excluding those which they've only ever used once). extisp.icio.us text gives you a random textual scattering of a user's tags, sized according to the numbe
Folksonomic Flaws?...In this article we look at what makes folksonomies work...We begin by looking at the issue of "sloppy tags", a problem to which critics of folksonomies are keen to allude, and ask if there are ways the folksonomy community could offse
Because tags are relativized, personal, idiosyncratic views can coexist and thrive in the form of tags, in spite of their inconsistencies. Readers of texts on the Internet become individual interpreters, despite the document author's intent...Yet, a state
This article looks at the evolving crop of social bookmarking tools, their functionality and examples of use. The goal is to help nonprofits understand the value of using social bookmarking tools and to determine which social bookmarking tool would best s
This article outlines the process involved in transforming the del.icio.us user API XML document into an HTML fragment. Because the XSLT processor is compiled, and therefore runs significantly faster than interpreted Javascript in the browser, I push as m
Spannerworks, a search engine marketing company, has published a handy dandy guide to social media (PDF). The ebook covers the basics of blogs, podcasts, social networks, tagging, communities and Second Life.
wOW! Search on 'metabolic AND syndrome' came up at zero, but shifting to 'metabolic,' I got SKILLIONS of articles related to "metabolic syndrome." GOOD ones!
Stock Cloud began as data mining experiment with a very simple goal — "Could we extract Business Partnerships by tracking press releases?" To accomplish this we selected a press release distribution agency, MarketWire, and began tracking releases. Usi
