Best known clustering algorithm for text documents ?

I would like to cluster my document based on terms founded in it , in deep i
have selected 15 terms would like to cluster these documents to K cluster,
terms are dependent from others such as :

Sport, computer, food, animal, ..etc till 15 terms or ( 15 term category  if
i build categories for each terms such as sport-cat combine most using sport
words (football, club, FIFA) etc. for others. ) is this correct procedure ?
for similarity measure i plan to use cosine similarity .. 

any way 
 i have calculated *TF.IDF* for my documents based on predefined terms (or
terms-categories) and building document-terms matrix, entries is the weight
of each term for corresponding document. Documents are nothing just are text
documents collected from many directories. 

for dimensionality reduction i'm not consider this process due my columns
are fixed is this true ? 

for feature selection i'm consider weight of *Tf.Idf* values as based
feature selection?

my questions are : 

1) what are best know algorithm can be used for this kind of clustering in
order the number of clusters k is not given previously? Weka has many
algorithms but as experience user what are best known algorithm are used for
this case and may gove better result?

2) if i classified these documents is this process can lead to use any other
clustering algorithm ?

Re : Re: features implementation

Thank you Eibe
I ve tested Stwv but the test set results was not good (strong variance).
Do you think my aim is not easy to get or is there some use cases pls?

Bug in CrossValidationResultProducer.java

Weka 3.8.0 

When doing cross validation with the "Weka Experimenter Environment", the results are not the same than using the explorer running each experiment individually (using the same seed) or calling the crossValidateModel method in weka.classifiers.Evaluation class.

That is because the evaluator is built inside of the method "getResult" invoked in this line:

Object[] seResults = m_SplitEvaluator.getResult(train, test); (line 393 in CrossValidationResultProducer.java)

and a evaluator is created for each fold.  Normally, the an evaluator is created for all folds. So, this can be easily fixed by creating the evaluator before calling the line refered before (393) and passing it as a paramater. So, the solutiong would be something like   

Evaluation eval = new Evaluation(m_Instances);
Instances runInstances = new Instances(m_Instances);
Random random = new Random(run);
....
for (int fold = 0; fold < m_NumFolds; fold++) {
       ....
        Instances train = runInstances.trainCV(m_NumFolds, fold, random);
        Instances test = runInstances.testCV(m_NumFolds, fold);
        Object[] seResults = m_SplitEvaluator.getResult(train, test, eval);
        ...

The difference in meaning and concept between Clustering and Multi-classification techniques


Dear Weka subscribers 

i would like to know the difference in meaning, approach and concept between
: 

Cluster similar objects into more than one cluster ( soft clustering ) where
objects can be found in more than one cluster , 

and soft classification where objects can be labeled into more than one
class ( Soft classification) 

in other words : 

cluster 1( object 1 , obejct2 ..etc ) and cluster 2(object1 , objetc 44..etc
) 
and 
object 1= class1 ( A, B,C) ?

thanks

features implementation

Hi Everybody
i m using lightside build on Weka api to classify a list of short 
strings. smo send back good metrics and i want now implement my model in 
my system with the right features.
My question is about the way to implement unigram, bigram and so in my 
own dev and i would like to know which is the best way to do that pls? 
Have i to found some codes like for example treetager ?

thank you very much in advance for your help and your time.

Best known Web Document classification algorithm ?

Dear Weka subscribers 

i would like to know what is the best and efficient ( time complexity,
effort, memory used ) unsupervised classification algorithm for following
data set , 
where features represented as vectors each column combine similar mining
words such as for sport features combine similar mining sport words (Bag of
terms technique-BOT) such ( NBA, FIFA, LBA, REAL MADRID club etc. ) 
i have been calculated TF.IDF for each features across all documents to
represent its weight in this matrix , 

now i'm plan to use unsupervised classification algorithm- hard
classification to declare any document to any class it will belong, 

so i'm confusing regard to use any technique here can be employed well such
( Bayes, SVM, Rochie etc. ) can some one tell me what is best know
classification algorithm can give better result in this case . 
and if i consider to used highest Tf.IDF values based on class which mean
when highest values found in any corresponding columns then related feature
column is a class of that document is this theory correct or i have did some
mistakes ? 

thanks with best regards .. 

Web-document ID                                           Features (BOT)

Questions about filter position and clustering algorithm in WEKA 3.8

Dear WEKA subscribers 

I would like to ask about : 

1- (Classification Via clustering )filter in Weka 3.8filter if missed or
changes in WEKA 3.8 , previously i used WEKA 3.7 and i have been used it,
when i modified my WEKA to 3.8 i can not find it , any help please when i
can found it , 

2- i have used also an algorithm for my data set with name of( MAKE density
clustering algorithm), which has found in clustering algorithm panel , i
would like to write about this algorithm in my project work but i cannot
found any density algorithm with name of MAKE density clustering algorithm
which is used by default K-means algorithm inside it, so is this any
algorithm belong to density group like DENCLUS, DBSCAN ,..etc. 

i would like thank any one can give me notes, names and any comment about
mention filter and algorithm with my regards , 

i have attached 2 images for classification and clustering process in WEKA
3.7 to be recognized by answer users , thanks

Using Ucanaccess to connect to database

Hello,
I am trying to connect my 64bit weka to MSAccess using the Ucanaccess direct jdbc driver. I get the errors shown below when I run Weka and it wont open the Explorer interface. Has anyone seen this and is there a solution/workaround to this?
 
I cannot use the JDBC-ODBC bridge shown in the DatabaseUtils.props.msaccess file that comes with Weka. I have a 32 bit office running on a 64bit machine and there were some changes made to enable other 64bit applications (Spotfire) access MS Access files. As a result of this I cannot load a 32 bit ODBC driver for MS Access. I can load the 64 bit driver but when I try to connect the 64 bit weka to ODBC I get an error (32 bit Weka to Oracle via a 32 bit ODBC driver works fine). I was trying to workaround these issues by using the Ucanaccess direct jdbc driver for MS Access.
 
Will try to sort out why Weka 64bit cannot connect to 64 bit odbc in the meantime.
 
I am running Java 8. Thanks in advance.
 
Regards,
Sanjay Pethe

Which classifiers are you using in your experiment? It appears that one or more of them are not serializable.
