How to Copy IE7 Search Providers List

I have found the following convenient yet safe way to copy IE7 search providers list from one computer A to another computer B.
(1) On computer A, add all desired search providers to IE7.
(2) On computer A, use regedit to find and export the following key to a .reg file: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\SearchScopes.
(3) Copy that .reg file from computer A to computer B.
(4) On computer B, run (double-click) that .reg file to import the corresponding registry key.

Am I a nerd?

Take this Nerd Test to find out how nerdy you are. I think it could actually serve as an interesting example for classification or regression.

Custom Search Engine

Google has a new service called Custom Search Engine as prat of their Google Co-op plan. It enables avdanced users to create a highly specialized vertical search engine that reflects their own needs as well as knowledge. There have already been some interesting applications, such as Tech Stuff Search, Product Search and Machine Learning Search.

Information Geometry

Information Geometry is a very beautiful theory that connects probabilistic/statistical models and differential geometry. Just read a physicist's interesting note on Information Geometry. It should be able to bring new insights into the field of machine learning.

"Beautiful is the first test: there is no permanent place in the world for ugly mathematics." -- G.H. Hardy

The Porter Stemming Algorithm

The 'official’ page for distribution of the Porter Stemming Algorithm has been revised and moved.

For Python (and other script languages), it is probably more efficient to use a C-implemented module (e.g., nltk.stemmer.porter) rather than taking the Python code straightforwardly.

MinorThird is a collection of Java classes for storing text, annotating text, and learning to extract entities and categorize text. It was written primarily by Dr William W. Cohen. It comes with a collection of publically-available extraction problems in Minorthird format (about 2Mb).

Minorthird differs from existing NLP and learning toolkits in a number of ways:

  • Unlike many NLP packages (eg GATE, Alembic) it combines tools for annotating and visualizing text with state-of-the art learning methods.

  • Unlike many other learning packages, it contains methods to visualize both training data and the performance of classifiers, which facilitates debugging.

  • Unlike other learning packages less tightly integrated with text manipulation tools, it is possible to track and visualize the transformation of text data into machine learning data.

  • Unlike many packages (including WEKA), it is open-source, and available for both commercial and research purposes.

  • Unlike any open-source learning systems I know of, it is architected to support active learning and on-line learning, which should facilitate integration of learning methods into agents.
