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.

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.
