New from Google Research

Google Research has launched COVID-19 Research Explorer. This has “a semantic search interface” that enables better search and discovery across “more than 50,000 journal articles and preprints”.

A new group test of search

Which Academic Search Systems are Suitable for Systematic Reviews or Meta-Analyses? Evaluating Retrieval Qualities of Google Scholar, PubMed and 26 other Resources, October 2019.

“Our tests revealed that the help files of numerous search systems promise a Boolean search functionality that our tests could not verify. These findings were especially alarming because users of such systems rely on functionalities that they assume work properly, but that may not be the case.” … “our results contradict systematic review guidance that assumes that “all the search engines in some way [would] permit the use of Boolean syntax operators to expand or restrict the search””.

Regarding… “full Boolean search strategies” the authors also noted that “Google Scholar [does] not offer such functionality”. The word “full” here is the critical word, and indicates that NOT is still a missing operator for Google Scholar.

For open access, this new test concludes that those outside of biomedical research… “are limited to the multidisciplinary system BASE” for discovering open access material, but that unspecified… “other open, or partially open search systems that fail to meet the criteria for query-based search might still be useful for supplementary search methods.”

Review of Cabell’s Predatory Journal Blacklist

A new review of a paywalled up-to-date blacklist of predatory journals, “Cabell’s Predatory Journal Blacklist: An Updated Review”, at the Scholarly Kitchen.

SciRide Finder

SciRide Finder is a newly launched search tool that searches Medline/PubMed, but it limits the search to just those “statements, numbers and protocols” which cite other publications. A fine idea, but the core concept may initially be a little difficult for humanities scholars to fathom. You can see what they’re talking about, in this visual example…

SciRide Finder appears to have crashed under the initial surge of traffic, but is “under maintenance” and should be up again soon.

Mamont

I’m pleased to find another good FTP search engine for filename searches, Mamont. The best of the bunch on Biskbard’s survey.

Caught in the Web

“Building a mission critical research ecosystem for Russia” (Feb 2019). The glossy report appears to be at attempt to sell Web of Science to Russia, and states…

The Web of Science platform is the first and only comprehensive, publisher-neutral discovery resource for trusted, peer-reviewed Open Access content.

More on OA in Web of Science and Scopus

A new February 2019 paper, from the German Centre for Higher Education Research and Science Studies, testing existing methods for auto-detection of OA papers in Web of Science (WOS) and Scopus. The conclusions are about what you might expect — that it’s easier said than done, even with such well-behaved services, and even then it’s partial.

But as part of the study a research assistant valiantly undertook further manual checking by hand. They found that OA full-text links there were broken at a rate of 17%…

“a further manual check found about 17% of OA publications are not accessible … 17.57% in WOS and 16.74% in Scopus.”

OOIR

The new OOIR List. Currently with 849 journals in its List, these being from Web of Science’s SSCI journals in social studies. 119 of the titles on the OOIR List are flagged as Open Access, though a good number of these are greyed-out and not tracked (because they don’t bother to also submit to CrossRef).

Evidently Web of Science only covers 119 such OA titles, which means its OA coverage in this area has hardly budged since 2015 when Web of Science was only showing 116 titles in OA in social studies.

Within that very limited range, what OOIR is trying to do with its titles seems interesting, by providing an aggregated ‘latest’ / ‘trending’ / ‘active journals’ dashboard. It’s neatly presented, and there are also per-journal metrics over on the Statistics tab.

Apparently the service is focussed on recent papers, and “OOIR does not link to papers published before Nov 2018”. A previous RSS-feed based version, for politics and diplomacy, was titled Observatory of International Relations (OIR). But this has now been shut in favour of OOIR.

I guess the question now is, would it be possible to build something bigger and similar and slightly shinier, that could provide a public tracking-dashboard for all such material of use to those interested in timely new research on politics, diplomacy and related matters? Zak Kallenborn has some ideas on that in his recent article “Academic Paywalls Harm National Security”.

Humanists’ digital workflows

New in DHQ: Digital Humanities Quarterly, “Researcher as Bricoleur: Contextualizing humanists’ digital workflows”. A small-scale observational study from 2016, building on a larger ‘Digital Scholarly Workflow’ study. The body is made up of case studies and commentary. Here’s the tale of a search by a historian for “1916” “November” “War Council”:

Audrey, a professor of history, searched for literature on an event that took place in 1916, and for which she had only partial information. Audrey’s search starts with her personal collection of notes written in Word and stored on the internal hard drive. She uses a Word search function that queries the folder for a supposed event name, but this search yields no result. Audrey then switches to her browser and the online search. She logs on to the Penn State library and enters a search phrase composed of three descriptors into the discovery search interface, LionSearch. This attempt does not yield any results either.

“Okay, no problem, I’m going to go to some of my favorite databases,” Audrey says optimistically, and, using the same search phrase, she continues her search in the Historical Abstracts database. “All right, I need another field. It happened in Rome,” she comments still optimistically, and expands her search with one more field, which reads “Rome.” Still nothing. “Seriously?!,” Audrey exclaims with annoyance. “All right, let me just do ‘war council,’ something more specific,” she says with reasserted optimism, and changes her search phrase accordingly. Failure again. “Really?!,” Audrey laments in shock. “I would have thought it was more important.” Audrey then reaches to her bookshelf and grabs a book. She reads through a few pages, trying to find any additional information that could help her search. Nothing. But Audrey is not ready to give up yet.

She returns to her library search and adds “November” as one more search field, trying to make her query as precise as possible. No results. Still, Audrey does not give up, and, instead of adding one more search term, she decides to change her search phrase. She creates a new search phrase, again composed of three descriptors as the possible event name. “Nope. All right, strange,” Audrey says quietly, confident that any further search would be pointless. “You would think someone must have written an article about this. It was the time that the different allies got together and hammered out a strategy…,” she continues murmuring, but discontinues her library search.

Instead, Audrey decides to try her luck with Google Search. She enters the search phrase and the Wikipedia entry pops up right away. “See, that’s the thing,” Audrey comments. “One would love to use more scholarly resources, but I just typed [the search phrase] and it’s up there [on Wikipedia]! Sadly, Historical Abstracts was not of too much use; the most useful one was still Wikipedia,” this historian concludes.

The problem here appears to be that the Supreme War Council of the three allies was created in November of 1917, not 1916. Only by switching the search terms from 1916 to 1917 does the Wikipedia page mentioned appear, so one has to suspect that there was some finessing of the search before hitting Google Search.

Error rates for Google Scholar citation parsing

Another new prodding of Google Scholar, this time from the latest First Monday “Testing Google Scholar bibliographic data: Estimating error rates for Google Scholar citation parsing”…

While data quality is good for journal articles and conference proceedings, books and edited collections are often wrongly described or have incomplete data. We identify a particular problem with material from online repositories [where there appears to be] considerable inhomogeneity in the implementation of data standards [and] a mismatch between repository software and the harvesting protocols employed by Google Scholar.

One of Scholar’s other problems is that it includes Google Books results. While 30% of the time its Google Books inclusions can useful, there is no way to exclude Books results. One might want to exclude because Scholar still can’t seem to determine a proper book from a robot-produced shovelware ebook that assembles public-domain content. Scholar has no ‘edition authority’ which states that the Joshi-edited and annotated Penguin Classics edition of H.P. Lovecraft’s “Dexter Ward” is the gold-standard and that it has a text that has been fully corrected of the many textual errors, omissions and editing mistakes of previous decades. Unlike the public-domain shovelware ebooks that flood Amazon and (often) Google Books.

A basic undergraduate level search, for instance, for Lovecraft “Dexter Ward”, demonstrates the problem on the first page. Joshi is nowhere to be seen, and the searcher is hammered by links to shovelware ebooks (or worse), often with citation counts that suggest they are legitimate.
