Technical Session I MCRDR Classifier & Database Design Presenter Yangsok Kim School of Computing

School of Computing, University of Tasmania Scope Explain MCRDR classifier installation process Explain MCRDR classifier database table structure Explain relationship between classification process and database table structure

School of Computing, University of Tasmania Download MCRDR classifier from the Unit Web page ( 2007/project.html) 2007/project.html Create a folder for MCRDR (e.g., mcrdr_classifier) and unzip the download file Execute MonClassifier_KXA exe Configure database setup MCRDR classifier Installation Click this icon Select “Database” Fill in database information (host, userid, password, database name) Click reconnect button Select username and fill in username and passowrd

School of Computing, University of Tasmania Database You can see your database via phpMyAdmin interface ( ) 9 tables are client side (classifier table) and 7 tables are server side table. Server Tables Client (Classifier) Tables

School of Computing, University of Tasmania Database – Server Side Tables tbmonservsite tbmonservsitetree tbmonservarticle Join tbmonservsite and tbmonservsitetree SELECT a.MonSiteID, b.MonSitePID, a.MonSiteURL, b.MonSiteName, b,nTime FROM tbmonservsite a, tbmonservsitetree b WHERE a.MonSiteID=b.MonSiteID

School of Computing, University of Tasmania Import Monitoring Webpages tbclassify_user_article tbmonservarticle If you want to article details, you need to join tbclassify_USERNAME_article and tbmonservarticle e.g. SELECT b.ArticleID, b.Title, b.Body FROM tbclassify_user_article a, tbmonservarticle b WHERE a.ArticleID=b.ArticleID This table date is filled when you import monitoring Web pages. OR After registering Web pages, the MonServer automatically feeds newly collected articles.

School of Computing, University of Tasmania Rule base MCRDR classifier maintains rule base for classification Rule base is an n-ary tree Each node is a rule Rule consists of condition parts and conclusion –Condition Attributes are Title, Body, and All of a article –Each condition evaluates whether the condition words is included in the articles –Conclusion is a folder of the classification structure

School of Computing, University of Tasmania Rule Base IF THEN Root A B C Title: a,b,c,g,f Body: c, d, k,m Classification Structure Article Root Rule 1 Rule 2 Rule 3 Rule 4 Title includes {a, b} AND Body include {c, d} Classify into folder C Rule Base

School of Computing, University of Tasmania Rule Base tbclassify_user_ruletree tbclassify_user_rulecondition Each rule has parent rule id There are two types of rules(refine rule(0), stop rule(1) Conclusion ID is a folder ID CornerstoneCaseID is an ArticleID that is used for rule creation Each rule has multiple conditions Condition word, which is case sensitive Three condition types – 0:Title, 1:Body, and 2:ALL

School of Computing, University of Tasmania Rule base tbclassify_user_articlefolder This table stores classification results

School of Computing, University of Tasmania Classification Structure There are predefined classification (folder) structure. Don’t change any folders!! Each folder is used as the conclusion of rule Classification structure is a tree.

School of Computing, University of Tasmania Classification Structure tbclassify_user_foldertree Each folder’s parent folder ID Each folder has unique ID

School of Computing, University of Tasmania Rule Creation With MCRDR classifier, user incrementally creates rules that classify documents. Rule creation initiated –1) when the classifier doesn’t provide recommendation or –2)when the classifier gives wrong recommendation Rule can be refine rule or stop rule

School of Computing, University of Tasmania Rule Creation - Basic Select Article form the Article List Click Knowledge Acquisition icon Select a folder that this article is classified Select condition word Select condition type Condition word is added here Display articles that satisfies current rule. We need to validate these cases Select cases that should not classified by current rule System place the selected article in this pane System shows keywords that are not found in the excluded cases. Click this button to create a rule New rule added to the rule tree If you want to finish click this button

School of Computing, University of Tasmania Refine Rule View current recommendation Select article that should be refined Click knowledge acquisition icon Select a folder under the current recommended folder The following process is same the basic rule creation process New rule is added under the parent rule

School of Computing, University of Tasmania Rule Creation – Refine Rule tbclassify_user_ruletree tbclassify_user_rulecondition tbclassify_user_articlefolder New Rule is added Classification result has been changed

School of Computing, University of Tasmania Rule Creation – Stop rule Select an article that should not be classified this folder Select current recommended folder and choose deselect menu from the shortcut menu After selecting “Deselect” menu, follow the basic rule creation process Stop rule is added under the current fired rule

School of Computing, University of Tasmania Rule Creation – Stop rule tbclassify_user_articlefolder This conditions are added This result is deleted This rule is added. Note the RuleType and ConclusionID
