T U TO R I A L 2Basics of Web Mining

Raghu KrishnapuramIBM Solutions Research Centre

Audience: This introductory tutorial is meantfor researchers and graduate students interest-ed in Web mining, document classification andpattern analysis. Some basic background inprobability and statistics, linear algebra, andoptimization techniques would be helpful. An effort will be made to make the tutorialaccessible to computer professionals.

Course Description: The proliferation of infor-mation on the World Wide Web has made per-sonalization of this information space a neces-sity. Web personalization/mining has two com-ponents: (1) tailoring the content delivered tothe user from a Web site; and (2) exploring theavailable Web objects such as URLs, Webpages, and snippets, and categorizing them.Mining typical user profiles from access logs isan important component of Web personaliza-tion. Similarly, clustering Web documents intogroups of related items is required in manyapplications of Web mining. The algorithmsfor Web personalization and mining need to bescalable, robust (so that they can deal withoutlier data), incremental (since all data maynot be available at one time), and fuzzy (sincecategories are rarely crisp in practice).Moreover, certain types of Web objects (suchas URLs) cannot be represented by numericalfeatures, and therefore suitable similariy mea-sures need to be defined. This tutorial willreview various approaches that deal with theabove-mentioned aspects of Web mining.

Lecturer: Raghu Krishnapuram("http://www.mines. edu/fs_home/rkrishna/")received his Ph.D. degree from Carnegie MellonUniversity in 1987. He has held academic posi-tions at the University of Missouri, Columbia,and at the Colorado School of Mines, Golden,Colorado. Currently he is a research staff mem-ber at IBM India Research Lab.

T U TO R I A L 6Weaving the Semantic Web: Mining Hypertext and

Semistructured DatabasesSoumen Chakrabarti

Indian Institute of Technology, Bombay

Audience: This tutorial is targetted towardsresearchers and graduate students interested indatabases, data mining, and hypertext. Somebackground in elementary probability andrelational data models will be helpful. Effortswill be made to make the tutorial accessible tocomputer professionals.

Course Description: With over a billion pagescovering most areas of human endeavor, theWorld-wide Web is a fertile ground for datamining research to make a difference to theeffectiveness of information search. Today,Web surfers access the Web through two dom-inant interfaces: clicking on hyperlinks andsearching via keyword queries. This process isoften tentative and unsatisfactory. Better sup-port is needed for expressing one's informa-tion need and dealing with a search result inmore structured ways than what is availablenow. Data mining and machine learning havesignificant roles to play towards this end. In thistutorial, we will survey recent advances inlearning and mining problems related tohypertext, in general and the Web, in particu-lar. We will review the continuum of super-vised to semi-supervised to unsupervised learn-ing problems, highlight the specific challengeswhich distinguish data mining in the hypertextdomain from data mining in the context ofdata warehouses, and summarize the key areasof recent and ongoing research.

Lecturer: Soumen Chakrabarti("http://www.cse.iitb.ernet.in/~soumen/")received his B.Tech in Computer Science fromthe Indian Institute of Technology, Kharagpur,and his M.S. and Ph.D. in Computer Sciencefrom the University of California, Berkeley.

It is primarily geared towardspeople who already are very fluent in Java andwish to understand what goes on under thehood. This is not an introductory tutorial andis not suitable for individuals learning Java astheir first programming language.

Course Description: This tutorial will discuss theunderlying infrastructure inside Java VirtualMachines such as Garbage Collection mecha-nisms, performance issues for multithreadedapplications, compilation models for Java, anddeveloping multi-language Java applications. Itwill focus on these mechanisms from the point ofview of developing and deploying Java on theserver-side. It will be structured into 4 parts for a1/2 day (4 hr) tutorial.

Part 1: Compilation Models for Java (1 hr)Interpretation, Just-In-Time compilation andnative Ahead-Of-Time compilation. Part 2: Multilanguage Java Programming (1 hr) Options available for developing multi-language Java applications, Java Native Interface,Performance issues for Multilanguage Javaapplications.Part 3: Multithreading in Java (1 hr)Mapping of Java threads to OS threads,Scaling of threads, Synchronization/Locking.Part 4: Garbage Collection issues (1 hr)What to expect from your Garbage Collector? Some discussion on GC mechanisms in currentproduction JVM's (Classic JVM, HotSpot/IBMJVM, gcj).

Lecturer: Suresh Srinivas, is engineering manag-er of the Java Compiler Group at SiliconGraphics. He received his Ph.D. from IndianaUniversity, specializing in parallel computingwhile working in the Extreme Computing Group.He joined the SGI Compiler and Tools Groupand worked on performance tools, Java MIPS JITcompiler, and other Java VM porting and tuningissues. He is passionate about computer lan-guages and their implementation, and hasworked on a variety of language systems, such asJava, C++, pC++, Scheme, and Emacs/elisp.

T U TO R I A L 8Mobility Management in Dynamic Networks

Subir Das, Anthony McAuley, and ArchanMisra, Telcordia Technologies

Audience: The tutorial is intended for network-ing researchers, designers, engineers, educa-tors and graduate students who are interestedin getting insights into future dynamic net-works. Those working outside this area canget a high level overview of this rapidly chang-ing field. It is also intended for networkproviders who are building future 3rd and 4thgeneration wireless IP networks.

Course Description: To provide heterogeneityand flexibility, future dynamic networks willnot only use IP for routing, but also for user-network signaling. For example, 3rd genera-tion wireless networks will use IP for func-tions such as configuration, registration, ser-vice negotiation and mobility management.Support for mobile operations, the keystrength of a wireless network, requires thenetwork to not only track the current locationof nodes, but also provide continuous connec-tivity while roaming. Different mobilityschemes have different characteristics in termsof latency, security, flexibility, number ofaddresses, and robustness. An overall solutionrequires deep understanding of existing state-of-the-art solutions, as well as their merits andde-merits. Clearly well-known solutions, suchas Mobile IP and SIP, will play a key part inany overall IP mobility solution. For dynamicnetworks, however, there are several issuesthat need further investigation.

While the first part of this tutorial gives abrief overview of IP in dynamic networks,configuration and registration protocols androuting for dynamic networks, the second partprovides an in-depth description of mobilitymanagement schemes for various types of net-works and shows how several representativeapplications and network characteristics dictate the correct choice of mobility manage-ment scheme.

Lecturer: Subir Das is a Research Scientist inthe Wireless IP networking research depart-ment, Telcordia Technologies, Morristown,NJ. He received his Ph.D. in ComputerEngineering from E & ECE Department, IIT,Kharagpur. From 1997-99, Dr. Das was a fac-ulty member in the same Department.

About Bangalore: Bangalore is the capital of the state ofKarnataka and the fifth largest city in India.This cosmopolitan city, home to the IndianInstitute of Science, many IT, aerospace andhigh technology industries, is often called theSilicon valley of India. Situated at an altitudeof approximately 1000 meters above sea level,Bangalore enjoys a pleasant climate through-out the year. The city's prominent architectur-al landmarks include the Vidhana Soudha(Legislative building), the Palace of the formerMaharaja of Mysore and the 19th centuryFort of Tipu Sultan. Many historic and arche-ological sites, wildlife sanctuaries, natureresorts, and places of spiritual interest arewithin easy reach of Bangalore.

Sightseeing Tour:A one-day sightseeing tour around Bangaloreis planned for Thursday, 21 December. Pleasecheck the HiPC website for details.

Travel Checklist

Visa:All non-Indian-citizens are required to have anIndian visa to enter the country. Please allowyourself sufficient time (say 2-3 weeks) to procure an appropriate visa from your nearestIndian consulate. Please check the conferencewebsite for information about Indian consulates.

Flight Reservations:Flights to India tend to fill up well ahead ofthe December holiday season. We recommendthat you make your flight reservations about3-4 months in advance, to be on the safe side.

Vaccinations (shots):Many first-time travellers to India prefer toget preventive vaccinations.

Foreign Exchange:While international credit cards are widelyaccepted in commercial establishments inIndia, several places rely on cash transactionsin the local currency (Indian Rupee). We sug-gest that you carry some Indian currencywhen entering India or buy Indian currency atthe airport when you arrive. The currentexchange rate is about Rs. 45/- per US dollar.Once in India, you can buy additional Indiancurrency from local branches of Citibank,Thomas Cook, etc. However, it is typically difficult to convert Indian currency back intoforeign currency because of exchange regulations.

Hotel Reservations:Please make your hotel reservations ahead oftime so that you get your choice of accommo-dation. Check the conference website forinformation about a range of accomdations.

Time and Weather: The Indian Standard Time(IST) is 5 1/2 hoursahead of the Greenwich Mean Time(GMT)and is 13 1/2 hours ahead of the U. S. PacificStandard Time(PST). In December/January theweather is mildly tropical with temperaturesaveraging about 22 degrees Celsius (approx.70 degrees Fahrenheit) during the day andabout 14 degrees Celsius (approx. 55 degreesFahrenheit) during the night.
