Top-down and bottom-up research in biodemography
The most efficient way to make scientific progress in biodemography is to encourage bi-directional exchange between ‘top-down’ and ‘bottom-up’ research. This will entail exchange along the continuum of research from microscopic intracellular processes to population-level consequences. In addition, our understanding of the biology of aging and its demographic consequences will be enriched by mut...
متن کاملBottom-up Game Studies
In this paper, we endorse and advance an emerging bottomup approach to game studies that utilizes techniques from natural language processing. Our contribution is threefold: we present the first complete review of the growing body of work through which this methodology has been innovated; we present a latent semantic analysis model that constitutes the first application of this fundamental bott...
متن کاملBottom-Up Argumentation
Online social platforms, e-commerce sites and technical fora support the unfolding of informal exchanges, e.g. debates or discussions, that may be topic-driven or serendipitous. We outline a methodology for analysing these exchanges in computational argumentation terms, thus allowing a formal assessment of the dialectical validity of the positions debated in or emerging from the exchanges. Our ...
متن کاملBottom-Up Earley Deduction
We propose a bottom-up variant of Earley deduction. Bottom-up deduction is preferable to top-down deduction because it allows incrementai processing (even for head-driven grammars), it is data-driven, no subsumption check is needed, and preference values attached to lexical items can be used to guide best-first search. We discuss the scanning step for bottom-up Earley deduction and indexing sch...
متن کاملA Politics Mash-Up
Phase 1: Web robot searches news sites with keywords related to the upcoming election and then fetches the search results. At this point if the site gives all the necessary information, the robot is done. If not, it proceeds to next step. Phase 2: The robot visits popular web search sites where past news articles are already indexed, query for a new set of keywords constructed from previo...
