Emergency medical residents’ use of google for answering clinical questions in the emergency room
June Abbas (OK) et al (et al includes some doctors, a librarian)
(wow!) Internet resources have displaced textbooks in the ER bcs time constraints. Started 2007 – demographic questionnaire plus pre-test (familiarity, etc), plus questions able to answer (medically sure), closed book. Google test. Buffalo General Hospital Library – using proxy to monitor use etc.
The % answered incorrectly went up from closed book to Google, the % of answers that were unsure went down… bad news.
Incorrect answers did not prevent residents from using clinical information from the internet
They used natural language searching – restating the question, occasionally omitted important words, typographical errors, rarely used Boolean operators or advanced search
They are using things meant for lay individuals (WebMD, eMedicine) – Google ranks these sites over the real medical sites.
They had not been trained in searching, did not recognize the difference between library resources and open web, search strategies were simplistic and naive
Implications are that real work needs to be done in both evidence based medicine and online searching
Mobile phone search for library catalogs
Ramona Broussard et al (Texas)
what are the challenges for creating mobile apps, what essential functions are needed, what are the cost benefit tradeoffs
Search by limited fields, see availability and highlighted map of where the shelf location is, can also scan barcodes and search for those.
Based on limitations of the devices, decided to create a task-based with a more narrow space.
Mobile options (Kaikkonen 2008) – do nothing (frustrating), tailored page, app (can use phone features, but users have to download)
they picked Android because java based can use Eclipse, and can test everything except for the scan. Took 2 of them coding 20 hours for 4 weeks.
kept task based – all in support of search the catalog, interface should be simple. Future work includes more of a survey
Triggering Memories with Online Maps
Peesapati et all (Cornell)
How do people use maps to reminisce?
The revisit rack: grouping web search thumbnails for optimal visual recognition
Rhys Morgan and Max L Wilson (Swansea)
(oh, I was on the plane with him)
the answer: it was a bad idea.
If thumbnails are better for refinding, a lot of what is done on the web is refinding, visual search is faster than reading text, and search engines can track users easily – they thought putting them at the top in a rack would help people, it didn’t
lots of other services have tried this including google off and on and ask. Jaime Teevan did visual snippets – essence of the page vs. thumbnails (whole page smaller).
200 px images. They also tried along the side and then a control condition.
HCI test – simple lookup task, and then a subjective/decision task. had them come back in 5 days and refind what the found.
“these are useless results”
“the benefit was highly dependent on the result being present” and that wasn’t very often and then it was more disruptive. Is only useful when answer is easily recognizable in that page of results.
other stuff: 25% refinding failed after 5 days, especially in the subjective task
Thumbnails might be good for exploratory search.
