When I say “<blank> is a question answering system. A question can be posed in natural language and … <blank> can come up with a very precise answer to that question” — what comes to mind to fill in the <blank>? If you guessed a system developed by IBM to appear alongside human contestants on Jeopardy, you’d be right. That quote comes from video posted by IBM earlier this year that is the topic of the first DLTJ Thursday Threads entry. This weeks other entries look at possible erosions of copyright first sale doctrine, the state of open access publishing, and a proposition for new definitions to terms of art in data modeling.
