Collaborative search on the rise?

I am seeing an interesting not-quite-yet-a-trend on the emergence of collaborative search tools. I am not talking about research tools such as SearchTogether or Coagmento, but of real companies started for the purpose of putting out a search tool that supports explicit collaboration. The two recent entries in this category of which I am aware are [...] → Read More: Collaborative search on the rise?

A quick study of Scholar-ly Citation

Google recently unveiled Citations, its extension to Google Scholar that helps people to organize the papers and patents they wrote and to keep track of citations to them. You can edit metadata that wasn’t parsed correctly, merge or split references, connect to co-authors’ citation pages, etc. Cool stuff.

Recall vs. Precision

Stephen Robertson’s talk at the CIKM 2011 Industry event caused me to think about recall and precision again. Over the last decade precision-oriented searches have become synonymous with web searches, while recall has been relegated to narrow verticals. But is precision@5 or NCDG@1 really the right way to measure the effectiveness of interactive search? If [...] → Read More: Recall vs. Precision

HCIR 2011 keynote

How much does time weigh?

As Miles wrote yesterday, our paper was accepted to SIGIR 2011. The idea that time has an impact in ranking documents is not new; the problem seems to be to know when to take it into consideration. For example, while Li and Croft showed improvements in ranking when incorporating the notion of recency, we found [...] → Read More: How much does time weigh?

When is one>two and seven==eight?

So Google recently released the Google books N-gram viewer along with the datasets. There’s been plenty of press about it, and the Science article based on this data is an interesting read. I was trying to come up with a simple, yet insightful query. My initial trial was modernism,postmodernism which immediately had me wondering about [...] → Read More: When is one>two and seven==eight?
