Coral Reef Conservation with 3D Technology.

Corals reefs provide an important habitat for many marine creatures through their "complexity": the numerous branching shapes and forms that allow fish and other species to make a safe home. The latest developments in 3D technology can help us understand this complexity and replicate it. This talk will demonstrate how we reconstruct 3D models of coral reefs using underwater drones, how we measure complexity and how we can reproduce that complexity with 3D printing to boost reef restoration and protect marine ecosystems, both in the UK and abroad.

Are Two Heads Better Than One?

An Exploration of Ambiguity in Crowd-Collected Language Decisions from the Phrase Detectives Game.

The online game-with-a-purpose Phrase Detectives has been collecting decisions about anaphoric coreference in human language for over 10 years (4 million judgements from 40,000 players). The game was originally designed to collect multiple valid solutions for a single task, which complicated aggregation but created a very rich (and noisy) dataset. Analysis of the ambiguous player decisions highlights the need for understanding and resolving disagreement that is inherent in language interpretation. This talk will present some of the interesting cases of ambiguity found by the players of Phrase Detectives (a dataset that will be made available to the research community later this year) and discuss the statistical methods we have been working on to harness crowds that disagree with each other.

Key note talk at Augmenting Intelligence with Bias-Aware Humans­in-the­Loop (HumL workshop series) co-located with TheWebConf (WWW2019).

Games with a Purpose?

How the Phrase Detectives language game provides insights into human language

"Games with a purpose" or GWAPs are a category of games that collect useful data from players as they play and have been used for projects ranging from search engine optimisation through to gene splicing. In this talk I present research from the Phrase Detectives language GWAP that has been collecting data for over 10 years on how humans interpret language and how ambiguity in language can be explored through a game.

Short talk at the Game AI Meetup (GAIM) in London.
