The Challenge is
Growing
According to some recent studies that have coveredon the tremendous growthincrease inin the amount of data being recorded and stored on
digital media, it is clear that the gap between this digitally stored datathe amount of data going to
storage, and our ability to
process itit is widening. The
primary driver for this phenomenon is the
a more aggressive relative of the familiar “Moore’s
Law”. Moore’s Law is the observation
that the computational power seems to doubles approximately every
18 months. The corresponding law in the world of digital storage is even more
amazing. Storage capacity, for a fixed price, appears to be doubling
approximately every 9 months! [1]. In a
world governed by these two empirical laws, the importance of the it becomes very clear why the fields of databases and of
Data Mining and Knowledge Discovery are growing in importance. From
a strategic perspective, our need to be able to navigate
and exploit the rapidly growing
universe of digital data will rely heavily on our ability to come up with the
right systems that can
scale towith thesethese growth rates, of growth and that allowing us to effectively
manage and mine the raw data.
The Data Mining field
is centers about developing algorithms for extracting
structure from data. Theis structure can take
the form of statistical patterns, models, and relationships
over the data. Viewed at a high level, these “structures”
are basic data reductions that enable us to summarize the data, to bring
it down in dimensionality to spaces thatin which we have some hope of
understanding and visualizing. These
structures provide the basis for, and to enable us to predict and
anticipate when certain events occur. When viewed at this level, one begins to
understand the fundamental importance of data mining in the future of the
digital data universe. For a more futuristic outlook, see the article [2].
Beyond
the Giants and the Monsters
A recent study
conducted at UC-Berkeley indicates
that humankind seems to be producing over two exabytes of information per year. [3]. This study confirms
the persistence of the original trends first uncovered in [4]. The amount of
information generated in 1999 constitutes more than 12% of the aggregate amount
of information generated by humankind in all of recorded history. We conjecture that the rate is more dramatic for the year 2000. I have not seen the computation done for the year 2000, but I am
sure that the rate is getting even more dramatic. It is interesting that thean overwhelming majority
of the collected data is never seen
by humans [4].
As recently as three years ago, people were
wondering how they willwould manage terabyte
databases. Jim Gray, who is familiar with the
systems and scalability issues ofwhen dealing with dealing
with very large databasesamounts of data, used to refer to
these databases as “Terror Byte”
databases. It is interesting that now we
have now gone beyond the gigabytes and the terabytes, and are now
worried about petabytes and exabytes. Interestingly, “Giga” derives from the
Latin term for “Giant”, and “Tera” derives from the
Greek term for “Monster”. A gigabyte is 109 bytes, while a terabyte is
1012
bytes. The next higher units up become have less colorful in names: Ppetabyte and Eexabyte. Interestingly, tThe next term is units up the the Zzettabyte (deriving
from the last letter of the Greek alphabet), and
then the Yyottabyte, indicating a
backtracking from going to the last letter.
In the Data Mining
field, it is fairly safe to think that we are wrestling with the issues ofin dealing with giants (gigabytes). We certainly have
note stepped up to the Mmonsters yet. It is worrisome that within this plethora of
names , we still worry that we barely have
anyfew ideas on how to to even approach the monsters. The terabytes are still indeed the “terror bytes”. However, given the
driving forces of technology out there, it is with urgency that we must start to see progress
in scaling to the larger
databases. With each year, the challenges will grow larger, and so will the corresponding pressure for
breakthrough advancement in data mining technologies,. Data
mining solution providers will be measured along the lines of successful real world applications. Integrating
with new generation
business practices is essential.in modes of providing data
mining solutions, and in real examples of their integration with the way the
new generation of business is conducted.
A large number of cCorporations currently are and have been collecting their business data. and the volume of this data
grows significantly every year.
Furthermore, with the spreadgrowth of E-commerce and the
World Wide Web, online stores are automatically collecting huge amounts of valuable data automatically. For
example, web servers typically generate large volumes of daily access logs data, that capturescapturing page the sequences
of page accesses for millions of
users. Sites can easily generates tens of gigabytes of
data per day. Thus, we can
easily witness the wide availability of huge amounts of data; data that was hardly
there three or four years ago. And the volume of this data grows significantly
every year.
However, it is very difficult to turn such data
into useful information due to the limited availability of scalable data mining
algorithms. For the algorithms
to be scalable, the execution time should increase linearly, or preferably
sub-linearly,
in proportion to the size of the input data. Traditional data analysis
algorithms generally do not scale up well
with limited system resources such as (e.g. main memory). Therefore, we are
now faced with exciting opportunities and great challenges for data mining to
develop efficient, scalable and efficient algorithms that are acceptable in large databases.
This “scalability challenge” goes beyond just the algorithms to include: . It includes how systems issues
are addressed, the delivery of serviceshow services and capabilities
are delivered, and the delivery of mining
results. Results how the results of mining areneed to be made usable and
useful for individuals in businesses
and organizations who knowing little about data mining, statistics, and other esoteric
technologies. This
challenge must be addressed for data mining to cross into its next level of
integration within mainstream business and the
daily operations of organizations.
Special Issue on “Scalable Data Mining Algorithms”
We focus this issue of
SIGKDD Explorations on the topic of Scalable Data Mining Algorithms, and we
welcome Kyuseok Shim as Guest Editor. On this challenging and exciting topic, eleven articles are
included in the section
on contributed
article section on scalable data
mining algorithms.
Kristin P. Bennett and
Colin Campbell contributed a nice tutorial article on support vector machines
that have become popular tools for data mining applications. Jiawei Han and
Jian Pei present a new methodology called frequent pattern growth that avoids
candidate generation in Apriori-style algorithms. This technique can be an
alternative solution for mining frequent patterns when the candidate generation
and test cost is very expensive in applications with long and numerous
patterns. Laks. V.S. Lakshmanan, Carson Kai-Sang Leung, and Raymond Ng describe
a data structure called segment support map that boosts the performance of
frequent itemset mining algorithms by computing sharper upper bounds on the
support and better exploitation of constraints. Wei Wang, Jiong Yang and Philip
S. Yu propose several models to address different types of noise and provide
scalable algorithms for each model. George Forman and Bin Zhang present a
technique for developing parallel versions of centroid-based clustering algorithms that
communicate only
through
sufficient statistics. The aApproaches for
exploiting and pushing user-defined model constraints to speed up the mining
process are discussed by Minos Garofalakis and Rajeev Rastogi. Such techniques
can help to improve the system performance significantly by focusing on only
interesting patterns by users. Thus, it is worthy of investigation for many
existing data mining algorithms. Claudia Diamantini and Maurizio Panti show
that compression capabilities of the Vector Quantizer architecture can be
exploited to find simple and effective classification rules when it is trained withusing a stochastic gradient
algorithm. William A. Maniatty and Mohammed J. Zaki address desirable design
features of parallel data mining algorithms and investigate a migration path
from sequential algorithms by considering an integrated hardware and software
approach. Yves Bastide et al. present the PASCAL algorithm, thatwhich improves Apriori -style algorithms based on pattern counting
inference thatand can reduce database
access significantly. Gregory Piatetsky-Shapiro and Sam Steingold propose a new
measure called L-quality that helps to compare predictive models by looking at
the entire lift curve. Stephen D. Bay et al. describe new data sets that are available
in the UCI KDD archive to help in evaluating scalable data mining algorithms.
Considering it is very difficult to get large real-life data sets to conduct
performance studies of scalable algorithms, this addition of large data sets to
UCI KDD Archive will stimulate and foster systematic progress significantly in
developing scalable data mining algorithms.

Concluding Remarks
With this issue of SIGKDD Explorations we launch our second volume of the newsletter. With our continued growth and
the continued growth of the field we need to grow Explorations accordingly. We are pleased to bring in two
changes to the editorial staff and format of your newsletter. We have invited
Paul Bradley to join the editoraleditorial staff as Associate Editor. We have also asked him to serve as Guest Editor
of this issue. This represented the second change in editorial format: future
issues will have themes and special topics with guest editors invited to cover each special topic. We shall of
course continue to include contributed articles on topics of interest and
conference and workshop reports. In
addition to serving as Guest Editor on this issue, Paul has also taken a major
load of additional work on producing this issue in his new role as Associate
Editor. Having welcomed Paul
aboard, we’ll let him introduce this issue’s special focus.
The
special issue section of
this issue SIGKDD
Explorations is focused on “Internet
Data Mining”. A large number of
corporations have been collecting their business data and the volume of this
data grows significantly every year. Furthermore, with
the spread of E-commerce and
World Wide Web, online stores are collecting huge amounts of
valuable data automatically. For example, web servers typically generate large volumes of daily access log data that captures the sequences of page accesses for
millions of users. Thus,
we can easily witness the wide availability of huge amounts of data that was
very difficult in the past. However, it is very hard to turn
such data into useful information due
to the limited availability of scalable data mining algorithms. For the algorithms to be scalable, the execution time
should be increased almost linearly in proportion to the size of the input
data. Traditional data analysis algorithms generally do not scale up well with
limited system resources such as main memory. Therefore, we are now faced with exciting
opportunities and great challenges for data mining to develop scalable and efficient algorithms
that are acceptable in large databases. We focus this issue of SIGKDD Explorations on the topic of “Scalable Data Mining Algorithms”.
The “Internet”
continues to provide the general population of computer users with innumerable
benefits (and possibly some drawbacks).
It also provides the data mining community with large amounts of data
and great challenges through new applications areas like customer relationship
management, e-commerce and web search.
As
the internetInternet expands, there is a
greater need to effectively index and classify content to support efficient
search and navigation. In addition, the
internetInternet provides businesses
with an operational platform for interaction with their customers 24
hours per day, 365 days per yeararound the clock,
without geographic or physical boundaries.
According to a Forrester report, “worldwide net commerce – both B2B and
B2C – will hit $6.8 trillion in 2004” [3].
Databases currently are (and will continue to be) critical components in
the e-commerce arena. The data
generated by this domain provide “all the right ingredients for successful data
mining” [1]. In addition to providing
some of the key foundations in internet content indexing, text mining
techniques may prove very useful in helping the end-user deal with the
information overload streaming down to her or him by processing email and other
electronic communication and prioritizing messages and tasks
[2].
While there is such
excitement enthusiasm and
opportunity for data mining in the internetInternet
arena is
exciting and intriguing,
the serious issue of privacy needs to be effectively handled. Although it is not only an issue with data
mining and the internetInternet, data mining
practitioners in this space should need to be
constantly aware of such the implications of tracking and
analysis technologies on privacy. Without properly addressing the issue of
privacy on the internetInternet, this abundant tap of
data may eventually flow much slower due to regulations, etcand other corrective
or preventive restrictions.
GGiven
the opportunities, challenges and issues touched upon above, we chose to focus this
issue of SIGKDD Explorations focuses
on the topic of “Internet Data Mining”. On this challenging and

Paul Bradley, please fill this part!!
Kosala
and Hendrik Blockeel contribute a survey on web mining research, providing an
overview of sub-areas and problems encompassed by web mining. Yiming Ma, Bing Liu and Ching Kian Wong
propose a web-browser-based graphical user interface for displaying, navigating
and annotating a set of discovered rules.
Sunita Sarawagi and Sree Hari Nagaralu discuss the notion, use and
implication of providing data mining models as services on the web. Stanley Loh, Leandro Krug Wives and José
Palazzo de Oliveira propose a concept-based approach to analyzing texts
extracted from the web using an interesting collaboration between human and
computer to obtain the final result.
José Borges and Mark Levene present a heuristic for speeding up a
previous system based upon a hypertext probabilistic grammar for extracting
browsing behavior from web log data.
Additional articles addressing general topics of
interest to the SIGKDD community include the introduction of a simple new
scalable k-means clustering algorithm proposed and evaluated by Frederik
Farnstrom, James Lewis and Charles Elkan.
We hope that this article prompts further discussion on scalable data
mining algorithms in general. A survey
and overview of algorithms discovering association rules appears by Jochen
Hipp, Ulrich Güntzer and Gholamreza Nakhaeizadeh, including several runtime
experiments. Alex Freitas provides a
position paper outlining differences between the classification task and that
of discovering association rules and raises many interesting points, hopefully
prompting further discussion on the subject from the SIGKDD community.
.
Reports from workshops and meetings of interest
include a report from Jeanne Behnke, Elaine Dobinson and others on the NASA
Workshop on Issues in the Application of Data Mining to Scientific Data. Coming from one of the early organizations
with a definite need to analyze large data sets, the topics discussed in this
report provide interesting insight into the relationship between the data
analyst and the domain specialist in scientific areas of interest to NASA. Dan Suciu and Gottfried Vossen have kindly
provided a report from WebDB’2000 following the ACM PODS/SIGMOD
conferences. Dimitrios Gunopulos and
Rajeev Rastogi have, similarly, kindly provided a report on the ACM SIGMOD
Workshop on Research Issues in Data Mining and Knowledge Discovery.
We hope that SIGKDD
Explorations continues to meet your expectations on covering timely topics and
events in this growing field. Our shift in format towards special focus topics
is not intended to limit the scope of our coverage of the field. We still welcome
articles and contributions, including position and idea papers as well as
controversial topics that stimulate discussion and deliberation. We hope the
special focus sections will allow us to continue the general breadth of

Server 3.0 and 4.0) and developing scalable algorithms for mining large
databases and architecting their fit with server products such as Microsoft SQL
Server and OLAP Services. In addition
to managing the DMX research group, he managed the core part of the development
team that is building providers in the SQL Server product group. He was also a driving force behind
establishing a new industry standard in data mining based on Microsoft’s OLE DB
API. Prior to joining Microsoft, Usama was at the Jet Propulsion Laboratory
(JPL), California Institute of Technology (1989-1995) where he founded and
headed the Machine Learning Systems Group and developed data mining systems for
the analysis of large scientific databases. For this work he received the most
distinguished excellence awards from Caltech/JPL and a U.S. Government Medal
from NASA. He remained affiliated with JPL as Distinguished Visiting Scientist
after he moved to Microsoft.
