Checking and Sharing Alt-Facts

Dynamic Facts in Large Team Information Sharing (Extended Abstract)

In this paper, we extend the large team information sharing problem to consider dynamic facts, where the value of facts about the environment being observed can change over time. Dynamic facts are challenging because the team must repeatedly converge to consistent, accurate beliefs over time, without necessarily knowing if or when the fact changes values. We discover an interesting, emergent ph...

Knowledge Sharing and Inconsistency Checking on Multiple Enterprise Models

The approach of Multi-Perspective Enterprise Modelling is now more commonly accepted and used in practice as a way to manage knowledge than ever before. However, the concept of applying multiple modelling languages to describe the same domain may still sound frightening to many. In addition to the cost, time and complexity involved, problems such as knowledge sharing between multiple models and...

Brute Facts, Social Facts, and Institutional Facts

Geographic regions (henceforth, regions for short) are spatially extended pieces of (near) earth surface that share some aspect of similarity across their extents. The most fundamental aspect of similarity shared within a region is "locational similarity"-proximity. But regions nearly always share common thematic content or activity too. That is, regions are defined not just spatially but accor...

Cheap Facts and Counter-Facts

This paper describes our experiments of using Amazon’s Mechanical Turk to generate (counter-)facts from texts for certain namedentities. We give the human annotators a paragraph of text and a highlighted named-entity. They will write down several (counter-)facts about this named-entity in that context. The analysis of the results is performed by comparing the acquired data with the recognizing ...
