Social bookmarking sites have become a starting point for people on the internet.  By reading only quality content that is handpicked by the community, it allows you to cut through the noise and maximize your time.  With new social bookmarking sites popping up every day, it can be overwhelming to try and keep track of them all.

Junoba is a social bookmarking search engine that will help display relevant results from popular social bookmarking sites like Digg, Reddit, Furl, LinkedIn and Mixx, into one central location.

Junoba functions similar to a normal engine like Google, however your results will only pull in content from those popular social sites you love.  With a clean and clutter-free layout, it is easy to navigation and find what you are looking for.

The real value of Junoba lies in the ability to only search sites where actual people are voting for websites, blogs, forums, wikis, discussion boards, etc…  With about 85% of searches being informational in nature, search only through sites that have been handpicked and reviewed by fellow users.

Personally I used to go to StumbleUpon, Digg, and Furl one at a time, to find what I was looking for.  Now all I have to do is perform one search on Junoba.  I can find what I am looking for fast!

Try it out for yourself!

What social bookmarking sites do you use the most?  How often do you utilize these sites?

The Visuwords online graphical dictionary looks up words to find their meanings and associations with other words and concepts. It produces diagrams reminiscent of a neural net. Learn how words associate.

Enter words into the search box to look them up or double-click a node to expand the tree. Click and drag the background to pan around and use the mouse wheel to zoom. Hover over nodes to see the definition and click and drag individual nodes to move them around to help clarify connections.

* It’s a dictionary! It’s a thesaurus!
* Great for writers, journalists, students, teachers, and artists.
* The online dictionary is available wherever there’s an internet connection.
* No membership required.

Visuwords™ uses Princeton University’s WordNet, an opensource database built by University students and language researchers. Combined with a visualization tool and user interface built from a combination of modern web technologies, Visuwords™ is available as a free resource to all patrons of the web.

The Visuwords™ Interface for the more technical:

To use the applet you only need to type a word into the search query at the top of the page and press ‘Enter’. A network of nodes or ’synsets’ will spring out from the word that you entered. A synset is essentially a single concept that is represented by a number of terms or synonyms. Synonyms are words with different spellings that convey the same idea.

For example when you lookup “seem”, you see that the word is connected to four synsets each represented by a green circle. Green denotes verbs so all of these synsets represent verbs. Two of these synsets have the lone word “seem”; one has two terms: “appear” and “seem”; and the third has three terms: “look”, “appear” and “seem”. Each of the four synsets has its own definition. Hovering over a node with the mouse will reveal all of the synonyms for a given synset as well as its definition. Some synsets will also show a few examples of usage. These synsets link to each other and to other synsets according to entries in the WordNet database.

You can zoom the model in and out by rolling the wheel on your mouse. You can click the gray background within the applet and drag the mouse in order to shift the whole model around so you can explore. You can grab any node and pull it away from the others to clarify connections.

Understanding the links between Synsets

With regards to “wheat” and “grain”, we see a cyan link from “wheat” pointing towards “grain” we can understand this to mean that wheat “is a kind of” grain. Here, “wheat” is a hyponym and “grain” is a hypernym.

In the case of verbs this same cyan link can be understood better by “is one way to”.

So, for example, to trot “is one way to” walk.

In these relationships, the hyponym is specific and unique.

For example, “Einstein” is an instance of a “physicist”.

In these cases the meronym in some way belongs to the holonym.

Examples: “robin” is a member of the “thrushes”, a “wheel” is a part of a “wheeled vehicle”, “caffeine” is a substance of “coffee”.
