V1.6 fixes Euclidean Normalised Similarity

ReverendSam — Mon, 27 Nov 2006 18:05:54 -0000

This previosuly in rare cases could of returned negative scores (multiple repeating tokens in the string). I.e. only a problem in a limited and repeated lexicon.

This issue is now resolved in newly released V1.6

V1.6 fixes tokeniser bug

ReverendSam — Mon, 27 Nov 2006 18:03:22 -0000

Version 1.6 fixed a tokeniser bug which can incorrectly tokenise in the case of repeating whitespace delimiting charcters. This inadvertantly adjusted token based metric scores in a few rare cases.

Version 1.6 released

ReverendSam — Mon, 27 Nov 2006 18:01:45 -0000

version 1.6 of simmetrics has been released.

added JUNIT test classes for all metrics and component parts.

fixes to a whitespace tokeniser bugs which can influence metric scores adversely in rare cases where repeating whitespace delimiting characters are found.

adjusted the method for the returning the normalised score function for the euclidean distance simmetric (this gave incorrect scores with comparison text containing multiple repeating terms)

CVS source control has now been added, you can always get the latest version of the code this way.

update to .NET SimMetrics

ReverendSam — Sun, 24 Sep 2006 22:06:23 -0000

another update to the .NET version. This removes the java support class created by the MS Java to C# converted. I have added in a new TokenUtilities class to provide the required functionality. There are also new tokenisers for qgram2, 3 and s as well as 2, 3 and s extended.
SGrams allow for errors in the words using a cci index.

This update cleans up the method and class names as per FxCop rules.

Lots of methods have been converted to properties, directory structures changed, unused source placed in separate directories.

Unit tests have been added and generics where appropriate.

Another update - where the Java Support class has been removed - will be released shortly.
