*** SECOND POSTING ON SIMILARITY METRICS *** About a month ago I posted a request for information, and interest, in the area of "similarity metrics". I am posting a second call for information now with the hope of furthering my base of understanding, and also to develop a base for the semi-formal survey I will be sending all respondents (this will be out in a week or so). I have received feedback from about thirty people. Most of the respondents have described their interests in this area, and many have provided abstractions of their methods for measuring similarity. This is very encouraging and I hope it continues. The survey will also be sent to a sizeable number of researchers that I know of already. My hope is to make this a cross-discipline study that provides insight from the Case-Based Reasoning, Analogical Reasoning, EBL, Information Retrieval, Behavioral Studies, Machine Learning, Child Psychology, etc. fields. At present a proposal for holding a workshop on this topic at IJCAI has been decided against. The topic may be presented as a panel discussion at a focused Case-Based Reasoning Workshop this year. --------------------- Original (edited) posting follows ------------------- SIMILARITY ... What does it mean? for ANALOGY What are the measures? for REMINDING Are there generalities or is it domain-specific? for EXEMPLARS ... Eliciation strategies, cues, weights, features, etc. I am performing independent research in the area of Case-Based Reasoning, CBR, and I am working on various metrics for similarity. In general, what ideas do you (the net-world) have about: - What about a new situation reminds you of a prior experience? - OR - How does one situation remind you of another? A little more focus might be how does one discriminate and weigh features of a new situation (case) in relationship to a large case-base of experiences that may or may not have a bearing on the new situation. Did that provide more focus or fuzziness!? This notice is sent out as a preliminary "attention-getter" to provide myself with some input to help form a more formal survey. Once written I hope to send it to a specific set of researchers (consisting mostly of people in the CBR, information retrieval (IR), doc. mngt. areas) and to anyone in netland that requests so. If anyone is interested in responding to any of this: - I will watch the "nets" for replies - Email to: j.a.king@dayton.ncr.com - Call: (513)-445-1090 before 4:30 (EST) (317)-478-5910 after 6:00 - Mail: NCR Corp. 1700 S. Patterson WHQ-5E Dayton, OH 45479 The survey will be finished and sent in the next week or two, so please let me know of your interest and what YOU might like to get out of such a study. Thank you for your time. Jim King
