Adversarial Geospatial Abduction Problems

Paulo Shakarian, John P. Dickerson, V. S. Subrahmanian
2012 ACM Transactions on Intelligent Systems and Technology  
In this paper, we define geospatial abduction problems (GAPs for short).  ...  We analyze the complexity of GAPs, develop exact and approximate algorithms (often with approximation guarantees) for these problems together with analyses of these algorithms, and develop a prototype  ...  geospatial abduction problems.  ...

MIST: Missing Person Intelligence Synthesis Toolkit [article]

Elham Shaabani, Hamidreza Alvari, Paulo Shakarian, J.E. Kelly Snyder
2016 arXiv   pre-print
This paper introduces the Missing Person Intelligence Synthesis Toolkit (MIST) which leverages a data-driven variant of geospatial abductive inference.  ...  In this paper, we formulate the problem of "finding missing person" with respect to information provided by FMG's experts, formally as a variant of the geospatial abduction problem (GAP) [22] .  ...  Geospatial abduction problem (GAP) [22] , on the other hand, refers to the problem of identifying unobserved partner locations (i.e., the location of a missing person) that best explain a set of observed  ...

John Eastwood, Salwa Barmaky, Sally Hansen, Erin Millere, Suzanne Ratcliff, Penelope Fotheringham, Heidi Coupland, Denise De Souza
2020 International Journal of Integrated Care  
In-depth, semi-structured interviews were audio-recorded, transcribed, coded and analysed using a context (C), intervention (I), mechanism (M) outcome (O) (CIMO) approach to abductive analysis.  ...  Eco's typology of abduction includes over-coded, under-coded and creative types of abduction (Eco, 1984 as cited by [32, p 23] .  ...  We approached the abductive analysis in three stages. The first step is the abductive inference embedded within the theory generation processes.  ...

A semi-systematic literature review, identifying research opportunities for more sustainable, receiver-led inbound urban logistics flows to large higher education institutions

Thomas H. Zunder
2021 European Transport Research Review  
Key concepts were identified and grouped as recurring, or with noticeable gaps - and therefore suitable for further research.  ...  The key gaps identified as worthy of note at this stage were: urban freight and procurement activity; private purchasing behaviour; HEIs and freight; barriers to sustainable procurement; engaging with  ...  I have detailed the local problem, the problems of urbanisation, logistics fragmentation, the challenges to sustainability and the abductive insight to address receiverled inbound logistics.  ...
