The Unfortunately Incomplete WUM Tutorial

This small tutorial should enable you to start the Web Utiliation Miner WUM! to create ane" demo minin# base! to import the $irst demo lo# $ile that comes "ith this distribution!

to create the %isitors& sessions contained in this lo# $ile! to build the a##re#ated lo# and to

e'ecute your $irst M(NT )uery "ith the M(NT )uery processor* (t co%ers the basic

techni)ues that you should +no" about be$ore minin# your o"n lo# $iles "ith WUM*

,d%anced techni)ues in usin# WUM are co%ered by the second part o$ the tutorial* (t is

stron#ly recommended to "or+ your "ay throu#h both parts o$ the tutorial be$ore startin#

your o"n minin# session*

(t is assumed that you success$ully installed the Web Utiliation Miner on your system and

modi$ied all necessary con$i#uration $iles* ($ you did not install WUM yet! please re$er to the

(nstallation uide that is part o$ this User .ocumentation and continue "ith the installation

research and education* The WUM team "ould really appreciate to #et all +inds o$ bu#

How to !reate a "ew Minin# $ase

24 30/07/2014 10:28

Each minin# project re)uires a minin# base "ithin WUM* , minin# base contains

descripti%e in$ormation as "ell as an Object 3tore P3E Pro database and %arious other $iles

created by the miner durin# the minin# process* (n order to create a ne" minin# base $or

this tutorial! please open the File menu and select Create Mining Base.

There are $i%e te't $ields $or the parameters o$ the ne" minin# base* Each minin# base

must ha%e a uni)ue name that may include blan+ spaces and numbers* The correspondin#

"eb ser%er UA7 can optionally be stored $or $uture use*

Each minin# base must ha%e its o"n directory to store the database and other related $iles*

(t is recommended to create a subdirectory in the directory data $or each ne" minin# base

be$ore startin# the miner* The minin# base o$ this tutorial "ill be stored in the e'istin#

directory data/demoWebSite* Blic+ on the button (Directory) ... to open a $ile dialo# o$ your

operatin# system* (n order to select the necessary directory websites/demoWebSite! please

select the directory and clic+ OK * ,lternati%ely! the name o$ an e'istin# directory can beentered in the correspondin# te't $ield*

24 30/07/2014 10:28

,$ter selectin# or enterin# the home directory o$ the ne" minin# base! the current dialo#

should - more or less - loo+ li+e this4

,dditionally! the local directory containin# the lo# $iles o$ your Web ser%er must be

speci$ied* The demo lo# $ile AccessLog.txt is stored in the same directory as the database*

There$ore! clic+ on the button (Log Files:) ... to open the $ile dialo# o$ your operatin#

system* Open the directory data/demoWebSite and $inally clic+ OK * to select the lo# $ile

directory*

24 30/07/2014 10:28

,$ter chec+in# the entered parameters! please clic+ the button OK in order to create the

ne" minin# base $or this tutorial* Blic+in# Bancel "ould abort the creation o$ a ne" minin#

base* (n this case! the $ocus "ould be returned to the main "indo" o$ WUM*

,$ter success$ully creatin# a ne" minin# base! the title o$ the main "indo" contains thename o$ the ne" minin# base in brac+ets* The ne" minin# base is no" open and can be

used $or $urther operations* There can be only one open minin# base at a time* The Object

3tore P3E Pro database consists o$ three $iles WUM.MiningBase.* that are stored in the same

directory* Please do not edit! modi$y or delete these $iles*

Please note that the underlyin# Object 3tore P3E Pro is a sin#le user database only* The

.CM3 o$ Object 3tore P3E Pro uses a loc+in# mechanism to secure that each minin# base

is accessed by e'actly one user at a time* The database o$ an open minin# base is loc+ed

by creatin# a subdirectory WUM.MiningBase.odx in its home directory*

($ the pre%ious minin# session ended abnormally! the loc+ directory can be deleted byWUM in order to start the miner* Ce$ore unloc+in# a database by $orce! ma+e sure that

there is no other user "or+in# "ith the correspondin# minin# base*

How to Import a %o# &ile

24 30/07/2014 10:28

,$ter creatin# a ne" or openin# an allready e'istin# minin# base! HTTP ser%er lo# $iles "ith

increasin# time stamps can subse)uently be imported into the minin# base* The import

module per$orms basic data cleanin# operations on each lo# $ile line and updates the

database "ith data o$ ne" %isitors and Web pa#es* (n order to import the small demo lo#

$ile into the tutorial minin# base! please open the File menu and select Import Log File.

The user inter$ace o$ the import module is depicted in the ne't picture* There are a $e"

parameters that must be speci$ied by the user be$ore a lo# $ile can be imported* ,part$rom simply enterin# the lo# $ile name and its $ormat! all parameters concernin# the data

cleanin# process should be considered %ery care$ully*

The te't $ield Filename contains the de$ault directory o$ HTTP ser%er lo# $iles* Cy clic+in#

the button (Filename) ...! you can speci$y the lo# $ile to be imported usin# the $ile dialo# o$

your operatin# system* ,$ter choosin# the correct $ile and clic+in# OK ! the complete lo# $ile

name "ill be sho"n in the te't $ield*

WUM currently supports $our "ide-spread lo# $ile $ormats* There is an e'ample lo# $ile line

o$ each $ile $ormat in the $ollo"in# table4 The e'ample lo# $ile AccessLog.txt corresponds to

the common lo# $ile $ormat* There$ore! please chec+ the Common Log File radio button*

emarks and an 'dditional *+ample

WUM accepts as input a template! i*e* an ordered list o$ %ariables and "ildcards! and a

conjunction o$ constraints on the statistics o$ those %ariables* (t $inds all se)uences! "hich

ta+en to#ether build a pattern actually a directed acyclic #raphF that satis$ies the templateand the constraints*

E'ample4 We are interested in an e%ent ' that occurs a$ter y "ith probability at least >?*

This e%ent y should appear in at least 188 o$ our se)uences* ' needs not occur

de 24 30/07/2014 10:28

immediately a$ter y! but it should not be more than ? e%ents a"ay $rom y* This

speci$ication produces the template y [0;5] x "here x and y are %ariables* The "ildcard

[0;5] stands $or any number o$ e%ents! and the inter%al [0;5] constraints the "ildcard

bet"een ero and up to ? e%ents* The constraints on x and y result in t"o restrictions4

y.support >= 100

and ( x.support / y.support ) > 0.95

To $ind the se)uences satis$yin# this template and constraints! issue the $ollo"in# M(NT

)uery4

select t

from node as a b, template y [0;5] x as t

where y.support >= 100

and ( x.support / y.support ) > 0.95

ou can use this )uery in the demo* Cut you ha%e to reduce the support o$ y! because

there is no e%ent that appears in more than @ se)uences* This "as just an e'ample* 5or

the $ormal de$initions and the description o$ the miner at "or+! please re$er to the

publications about the Web Utiliation Miner WUM*

When issuin# a M(NT )uery! WUM $inds all acceptable bindin#s $or the template %ariables*

, bindin# is a list o$ e%ents! i*e* o$ %alues! bound to the %ariables* , bindin# is acceptable i$

the e%ents comprisin# it appear in se)uences "hich4

con$orm to the template&s structure

ta+en to#ether constitute a #roup! the statistics o$ "hich satis$y the )uery

constraints

(n the abo%e e'ample! a UA7 *html in the dataset could be bound to %ariable y* , UA7

<*html could then be bound to x! only i$ there e'ists a se)uence "here <*html appears

"ithin L positions a$ter *html* 5or the bindin# to be acceptable! there should be at least

188 se)uences containin# *html and >? o$ them should contain <*html in at most L

positions a$ter *html* Those se)uences contribute the bindin# *html! <*htmlF*

WUM disco%ers all acceptable bindin#s $or the )uery and builds a na%i#ation pattern $or

each bindin#* , na%i#ation pattern is a directed acyclic #raph comprised o$ the se)uencescontributin# the bindin#4 the se)uences ha%e been mer#ed at common pre$i' and at each

e%ent o$ the bindin#*

The %isualiation tool o$ WUM can display a na%i#ation pattern in t"o "ays4

The template tree consists only o$ the e%ents comprisin# the bindin#* The e%ents

are annotated "ith the number o$ contributin# se)uences*
