Have you heard the one about how to drive BPM people crazy?
Ask them the question that drives CEP people crazy!
Last fall, at the RuleML conference in Orlando, was the first time I heard a consensus that a standard ontology of events and processes was sorely needed. I’ve had a number of discussions with others on this over the interim until today’s posts by Paul Vincent, summing up an OMG meeting in Washington, DC, and Sandy Kelmsley’s comments on a survey of 590 business process modeling notation users.

Radar Networks is accelerating down the path towards the world’s largest body of knowledge about what people care about using Twine to organize their bookmarks. Unlike social bookmarking sites, Twine uses natural language processing technology to read and categorize people’s bookmarks in a substantial ontology. Using this ontology, Twine not only organizes their bookmarks intelligently but also facilitates social networking and collaborative filtering that result in more relevant suggestions of others’ bookmarks than other social bookmarking sites can provide.
Twine should rapidly eclipse social bookmarking sites, like Digg and Redditt. This is no small feat!
The underlying capabilities of Twine present Radar Networks with many other opportunities, too. Twine could spider out from bookmarks and become a general competitor to Google, as Powerset hopes to become. Twine could become the semantic web’s Wikipedia, to which Metaweb’s Freebase aspires.

Not long ago I posted on the need to understand common concepts well. My example then concerned the need to understand time well enough to answer a question like, “How much did IBM’s earnings increase last quarter?”. Recently, in contemplating some training issues related to the integration of Haley Authority within Siebel, I came across examples phrasings from the documentation on Siebel’s web site, including:
- if an account’s location contains “CA” then add 50000 in “USD” for the account
- if an account’s location contains “CA” then add 70000 in “USD” on today for the account
Two things are immediately obvious.
- Oracle does not understand location.
- Oracle has an interesting, but nonetheless poor understanding of money.
Of course, I am intimately familiar with Authority’s understanding of money. However, Siebel needs more than Authority understands. Continue reading “Oracle should teach Siebel CRM about location and money”
James Taylor’s blog today on rules being core to BPM and SOA in which he discussed reuse had a particularly strong impact on me following a trip yesterday. During a meeting with the insurance and retail banking practice leaders at a large consulting firm, we looked for synnergies between applications related to investment and applications related to risk. Of course, during that conversation, we discussed whether operational rules could be usefully shared across these currently siloed areas, but we landed up discussing what they had in common in terms of business concepts, definitions, and fundamental truths or enterprise wide governance. It was clear to us that this was the most fruitful area to develop core, reusable knowledge assets.
In his post, James agrees with the Butler Group’s statement:
Possibly the most important aspect of a rules repository, certainly in respect of the stated promise of BPM, Service Oriented Architecture (SOA), and BRMS, is the ability for the developer to re-use rules within multiple process deployments.
I have several problems with this statement: Continue reading “Rules are not enough. Knowledge is core to reuse.”
We have been teaching a computer to answer questions like, “How much did IBM’s earnings change last quarter?” It takes a fair bit of knowledge, including how to understand English, to answer this question. But teaching it what a “quarter” is brought back memories of debates with some former CMU colleagues about what units are and how to model time. Since quite a few people ask me for help with knowledge engineering and ontological matters, I thought some might be interested in parts of those debates.As you will see, a strong upper ontology of common knowledge is required to understand common business knowledge. Leveraging such an ontology is the only way to deliver business rules for under $50.
Sentences like “do something if more than a number of possibly related things have happened within a timeframe of something else happening” or “do something if nothing happens within a timeframe following something happening” are extremely common in business process management (BPM), complex event processing (CEP), and workflow. With a sense of time, a business rules management system (BRMS) can support BPM, CEP, and workflow applications almost trivially. Without a sense of time, most BRMS force users to perform computations.
For example, without a sense of time and an infrastructure that supports it, the sentence “call a customer if no response is received within 30 days of notifying the customer of a delinquency” has to be transformed into something like “if a notice is mailed on a date and the notice is a delinquency and the date of notification has a day number then compute the date for checking by adding 30 to the day number and check for a response to the delinquency notice on the date for checking”. The checking on a date for a response to a notice must also be implemented as a database (or persistent queue) of events to be polled or triggered by application code. Then a second rule is required to implement the check, as in “if checking whether a response has been received to a notice and the notice was given on a date of notice and the notice was given to a customer and there exists no record of communication with the customer since the date of notice then call the customer”. (Note that this is actually how most BRMS products would implement this. The natural language approach I prefer handles the original sentence.)
The discussion here reflects the general structure and content that a usable ontology for business process management requires. Most users of business rules management tools will find the need to understand and engineer this discussion in their tool of choice. As my Haley Systems customers know, much of this is reflected in Authority’s built-in ontology and English vocabulary, but quite a few of the points discussed here reflect improvements, especially concerning the confusion between units and amounts.
As you will see the discussion takes careful thinking. Some readers may find it onerous. If at any time you have had enough (or if you simply cannot take anymore!), please skip to the end and decide whether to fill in the conclusions by revisiting the body.
