This chapter is devoted to understanding how the main ideas in graph theory and combinatorics optimization can assist insight-driven problem solving, and thereby, create public impact. The reader sees how such ideas have laid the foundation for apps such as Google Maps and how they are being used to improve our understanding of social networks, design transportation networks, create efficiency schedules for sports events, enhance cryptosystems, and improve the efficiency of supply chains. The reader also learns how analytics scientists have been able to learn from the amazing ability of nature in problem solving (swarm intelligence) and use this to develop effective insight-driven problem solving approaches that can yield powerful insights in addressing complex societal problems.

Reading or writing online user-reviews of places like a restaurant or a hair salon is a common information practice. Through its Local Guides Platform, Google calls on users to add reviews of places directly to Google Maps, as well as edit store hours and report fake reviews. Based on a case study of the platform, this chapter examines the governance structures that delineate the role Local Guides play in regulating the Google Maps information ecosystem and how it frames useful information vs. bad information. We track how the Local Guides Platform constructs a community of insiders who make Google Maps better vs. the misinformation that the platform positions as an exterior threat infiltrating Google Maps universally beneficial global mapping project. Framing our analysis through Kuo and Marwick’s critique of the dominant misinformation paradigm, one often based on hegemonic ideals of truth and authenticity. We argue that review and moderation practices on Local Guides further standardize constructions of misinformation as the product of a small group of outlier bad actors in an otherwise convivial information ecosystem. Instead, we consider how the platform’s governance of crowdsourced moderation, paired with Google Maps’ project of creating a single, universal map, helps to homogenize narratives of space that then further normalize the limited scope of Google’s misinformation paradigm.
