Trends in Customer Matching Systems

Every year around this time, Raab Associates, Inc. updates its Guide to Customer Matching Systems. After changes for each vendor have been posted, we have a rare opportunity to step back and look for larger patterns. Here’s what we saw.
In particular, the search systems are noteworthy for considering the frequency of individual names within their logic. In practical terms, this means they require more precise matches against more common names. Frequency is most often used during the initial selection of records to submit to a detailed matching process. This reduces the number of records that must be matched against common names–an important consideration for online search systems–without excessively limiting the candidates compared to unusual names. Frequency is also sometimes used within the matching logic itself, on the theory that unusual names are more likely to be misspelled, misformatted, or otherwise mangled during data capture and processing. (SAS DataFlux and Ascential QualityStage [originally Vality Integrity] also use frequency in these ways, although they did not start out as search systems.)
To reduce their reliance on parsing and standardization, search systems may match against all words in a name field, rather than attempting to identify family vs. given names, or match against both original and standardized addresses rather than the standardized address only. This typically requires storing several versions of each reference record–another way to improve online response time, although at the cost of higher storage and initial processing expenses.
Search system vendors claim to be more accurate and easier to set up than their merge-oriented competitors. Of course, the competitors disagree. Both sides point to tests that support their position, but the painful truth is that results will vary greatly depending on the data, applications and technicians involved. So careful buyers have little choice other than to run tests of their own.
These capabilities have in turn enabled new applications to spot fraud, money laundering and terrorists. These are based on existing matching functions but still require product extensions for new user interfaces, audit trails, and reference list maintenance. Some also need new matching methods to find relationships among individuals and organizations. Surveillance is a new business for many matching vendors and often involves buyers who are not their traditional customers. But several firms report it already accounts for a substantial revenue stream.
Today, matching systems are used for more applications and requirements can change quite frequently. Companies also have less time and money for implementation and maintenance. Vendors have responded by adding graphical user interfaces, reports and other features to speed and simplify deployment. In theory, this could allow non-technical users to set up their own processing streams and business rules–although in practice such users rarely take on these tasks by themselves.
This type of expansion is typical of the software industry, and in particular of specialized products that become more widely adapted. The fundamental challenge faced by vendors in this situation is that once their tools become well understood, larger vendors of related products can easily add some version of the specialized capability and then squeeze the specialists into an ever-shrinking “best of breed” niche. Matching vendors already face precisely such competition from Ascential and SAS, which have both purchased and integrated specialized matching systems. Potential competitors including Informatica and Siebel have so far chosen to partner with matching vendors rather than acquire or replace them, but there are no guarantees this will continue.
Line extension is therefore essentially a defensive move. The specialists seek a large enough presence to justify remaining part of corporate infrastructures or, failing that, enough revenue from a smaller number of clients that they can still survive. Historically, such expansion has rarely succeeded: small software companies have a hard time supporting a large product line, and big competitors have an overwhelming marketing advantage. So the strong likelihood is continued consolidation of the matching market, as small companies drop out or, more likely, are acquired by larger firms for their technology. In other words, the changes we saw this year are just a hint of the changes yet to come.
