Semantic Matchmaking as Non-Monotonic Reasoning: A Description Logic Approach

Journal of Artificial Intelligence Research

Matchmaking arises when supply and demand meet in an electronic marketplace, or when agents search for a web service to perform some task, or even when recruiting agencies match curricula and job profiles. In such open environments, the objective of a matchmaking process is to discover best available offers to a given request. We address the problem of matchmaking from a knowledge representation perspective, with a formalization based on Description Logics. We devise Concept Abduction and Concept Contraction as non-monotonic inferences in Description Logics suitable for modeling matchmaking in a logical framework, and prove some related complexity results. We also present reasonable algorithms for semantic matchmaking based on the devised inferences, and prove that they obey to some commonsense properties. Finally, we report on the implementation of the proposed matchmaking framework, which has been used both as a mediator in e-marketplaces and for semantic web services discovery.

Need for social distancing boosts online matchmaking party business

The Japan Times

Undaunted by cancellations of parties and dating opportunities due to the coronavirus pandemic, many singles in Japan looking for marriage partners have opted for virtual gatherings. A total of 400 people took part in matchmaking parties in April via Zoom, the online conferencing platform of Zoom Video Communication Inc. The online parties were organized by LMO Corp. in Fukuoka Prefecture, which began holding the virtual gatherings in late March. In contrast, just 10 to 20 people had joined when the matchmaking agency launched its one-on-one online marriage-meeting service in January, before COVID-19 infections had become a major issue in Japan. "Following the virus outbreak, we were set to cancel a face-to-face matchmaking party scheduled for March, but it suddenly came to my mind to hold it in a virtual format," said LMO President Kota Takada, 46.


Why Are We Pretending Destiny 2's Guided Games Isn't Just Matchmaking, But Slower

Forbes - Tech

With Destiny 2's progression locked almost entirely into milestones, and me being a super infrequent raider, I've realized that time is running out for me to get my characters up to the cap before the Forsaken expansion comes out. A stupid goal, perhaps, given that power level is about to increase from 385 to 600, but one I'm shooting for all the same. That has led me to try to complete at least one more milestone regularly, the Nightfall, where I've turned to Guided Games in order to help me find a group. This is a system I've only rarely used, but now, trying to do it eight months after D2's launch, I'm finding it downright hilarious. I understand the original intent behind Guided Games.
