  1. Multidimensional pairwise comparison – the idea of human-oriented science in the light of artificial intelligence and value surveys– Balogh Anikó, Pitlik László, Szani Ferenc Apertus Nonprofit Kft. Magyar Tudomány Ünnepe / Emberközpontú tudomány - Tomori Pál Főiskola – Budapest – 2017.11.21

  2. MOTTO • „Science is what we understand well enough to explain to a computer. Art is everything else we do.” (Knuth, 1992 – Stanford, LCSI) Donald Ervin Knuth (1938-) professor emeritusStanford University. He created the language TeX.

  3. Pairwise comparisons • Pairwise comparison generally is any process of comparing entities in pairs to judge which of each entity is preferred, or has a greater amount of some quantitative property, or whether or not the two entities are identical. • „Whichone is more importantforyou? A or B?” • The method of pairwise comparison is usedin: • preferences, attitudes,housing market,voting systems, social choice, public choice, requirements engineering and multiagent AI systems. (https://en.wikipedia.org/wiki/Pairwise_comparison)

  6. Identifyingsameness

  7. Applicationinpractice • Collaborative content recommendation system • Reference: Bozóki’s (2006) description of Brain Farm • Brain Farm – collaborative knowledge management system of the Hungarian academia • Recommendations based on: • Keywords • Activities • Evaluations by users

  8. Recommendationsystembypairwisecomparisons • Users preferences of study programs, literature, online communities, fora, etc. • Users (students) compare two items, see above • Their opinions’ consistency becomes clear • When is it not consistent? • E.g. they claim, that two study programs, which are the same, are different = obviously this evaluation is false • Or the user has no opinion, no knowledge about a certain pair
