Toward Theoretical Measures for Systems Involving Human Computation.
Crouser, R. Jordan.
Abstract: As we
enter an age of increasingly larger and noisier data, the dynamic interplay between
human and machine analysis grows ever more important. At present, balancing the cost of
building and deploying a collaborative system with the benefits afforded by its use is
precarious at best. We rely heavily on researcher intuition and current field-wide
trends to decide which problems to ... read moreapproach using collaborative techniques. While this
has led to many successes, it may also lead to the investment of significant time and
energy into collaborative solutions for problems that might better have been (or have
already been) solved by human or machine alone. In the absence of a secret formula to
prescribe this interplay, how do we balance the expected contributions of human and
machine during the design process? Can we describe the high-level complexity of these
systems with the same robust language as we use to describe the complexity of an
algorithmic system? In this work, we investigate the complementary nature of human and
machine computation as used in visual analytics and human computation systems, and
present a theoretical model to quantify and compare the algorithms that leverage this
