Among its distinguishing features are the direct cooperation between domain experts and users, and the interaction with a knowledge maintenance system devoted to dynamically update the knowledge base taking care of the evolving scenario. The paper aims to discuss these issues.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Design\/methodology\/approach<\/jats:title>\n<jats:p>The WES development method is based on the Knowledge Acquisition Framework based on Knowledge Artifact (KAFKA) framework. KAFKA employs multiple knowledge artifacts, each devoted to the acquisition and management of a specific kind of knowledge. The KAFKA framework is introduced from both the conceptual and computational points of view. An example is given which demonstrates the interaction, within this framework, of taxonomies, Bayesian networks and rule-based systems. An experimental assessment of the framework usability is also given.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Findings<\/jats:title>\n<jats:p>The most interesting characteristic of WESs is their capability to evolve over time, due both to the measurement of new values for input variables and to the detection of new input events, that can be used to modify, extend and maintain knowledge bases and to represent domains characterized by variability over time.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title>\n<jats:p>WES is a new and challenging concept, dealing with the possibility for a user to develop his\/her own decision support systems and update them according to new events when they arise from the environment. The system fully supports domain experts and users with no particular skills in knowledge engineering methodologies, to create, maintain and exploit their expert systems, everywhere and when necessary.<\/jats:p>\n<\/jats:sec>","DOI":"10.1108\/prog-09-2016-0061","type":"journal-article","created":{"date-parts":[[2017,7,28]],"date-time":"2017-07-28T10:33:11Z","timestamp":1501237991000},"page":"235-258","source":"Crossref","is-referenced-by-count":12,"title":["Wearable expert system development: definitions, models and challenges for the future"],"prefix":"10.1108","volume":"51","author":[{"given":"Fabio","family":"Sartori","sequence":"first","affiliation":[]},{"given":"Riccardo","family":"Melen","sequence":"additional","affiliation":[]}],"member":"140","reference":[{"issue":"3","key":"key2020120523400588300_ref001","doi-asserted-by":"crossref","first-page":"170","DOI":"10.1016\/0950-7051(91)90029-2","article-title":"Systems development life-cycle for expert systems","volume":"3","year":"1990","journal-title":"Knowledge-Based Systems"},{"issue":"4","key":"key2020120523400588300_ref002","doi-asserted-by":"crossref","first-page":"389","DOI":"10.1023\/A:1008653328901","article-title":"Developing knowledge-based systems with MIKE","volume":"5","year":"1998","journal-title":"Automated Software Engineering"},{"issue":"2","key":"key2020120523400588300_ref003","doi-asserted-by":"crossref","first-page":"157","DOI":"10.1016\/j.ijhcs.2012.10.009","article-title":"From the knowledge acquisition bottleneck to the knowledge acquisition overflow: a brief French history of knowledge acquisition","volume":"71","year":"2013","journal-title":"International Journal of Human Computer Studies"},{"issue":"2","key":"key2020120523400588300_ref004","first-page":"17","article-title":"From handicraft prototypes to limited serial productions: exploiting knowledge artifacts to support the industrial design of high quality products","volume":"24","year":"2010","journal-title":"Artificial Intelligence for Engineering Design, Analysis and Manufacturing"},{"key":"key2020120523400588300_ref005","doi-asserted-by":"crossref","unstructured":"Baretta, D., Sartori, F., Greco, A., Melen, R., Stella, F., Bollini, L. and Steca, P.
