Some Discovery Citation Indexes in 2020

In terms of cross disciplinary citation indexes that are used for discovery, everyone knows of the two incumbants — Web of Science and Scopus(2004). Joined by the large web scale Google Scholar (2004), these three reigned as the “Big 3” of citation indexes for roughly a decade more or less unchallenged.

However 10 years later, around 2015 and in the years after, a new generation of citation indexes started to emerge to challenge the big 3 in a variety of ways .

As of time of writing in 2020, some of these new challengers have…

Tired of entering keywords and getting thousands of hits and not sure where to start your literature review? Or having the opposite problem and entering a keyword and getting few relevant results?

You are in luck, we are seeing the rise of a new class of innovative literature review mapping tools, built on the backs of increasingly open metadata and citations coupled with possibly some new machine learning techniques (particularly those that use machine learning on full text for citation contexts).

I track as many as a dozen such tools out there but here I list three of the latest…

In my last post, I talked about the state of retractions in the literature and how so much of the literature includes authors who probably unknowingly cites retracted works

As journals (possibly even peer reviewers) are increasingly screening citations for retractions, it might be also a good idea to do your own screening before you submit your manuscript to avoid embarrassment. It is one thing to cite on purpose a retracted work , another to be unaware of what you are doing.

Below I detail two types of tools you can use — firstly pre-submission manuscript health check tools and…

It’s 2020 and we are settling down into and getting used to life where COVID is the norm. What new research tools have emerged that are worth checking out?

Most of the items are the list are either brand new, or have interesting new features to look out for.

Prior versions —Feb 2020, July 2019, Dec 2018, July 2018,

  1. Further developments in scite (I) — more advanced search options
  2. scite visualization trees and scite reference check
  3. Semantic Scholar improves cited by screen
  4. More citation mapping tools — Connected Papers , Local Citation Network , Cocites , Papergraph
  5. 2D Search expands…

Starting your research in a totally new area and unsure where to start? Wouldn’t it be nice if someone had done the work for you already, surveying the research landscape of papers of importance and interest in the area you are interested in and even commenting and evaluating on the results?

Sounds like a pipe dream? Not really. Find one of the following types of research and things becomes tons easier as they bring together citation rich resources on a specific area as assessed by an expert in the area. Say the concept you are studying is “Servant leadership”. …

The value of open and interoperable metadata of scientific articles is increasingly being recognized, as demonstrated by the work of organizations such as Crossref, DataCite, and OpenCitations and by initiatives such as Metadata 2020 and the Initiative for Open Citations. At the same time, scientific articles are increasingly being made openly accessible, stimulated for instance by Plan S, AmeliCA, and recent developments in the US, and also by the need for open access to coronavirus literature.

TL;DR — This article shows you a reliable search strategy that you can use in Lens.org to find meta-analysis, systematic reviews, review articles of topics you are interested in regardless of your discipline to help kick start your research. I covered the rationale for doing this with Lens.org earlier, in this article, I will show an easy way to adept a well tuned search strategy to your topic of interest in 5 minute flat using 2D Search (a free tool that now supports Lens.org).

Starting off your research in a new area like leadership, creativity and overwhelmed by the amount…

It’s a new year, and here are more research tools to keep your eye out on. Most of the items are the list are either brand new, or have interesting new features to look out for.

1. Semantic Scholar is enhanced with Microsoft academic graph data and now covers more than just Computer Science and Life Sciences. JISC CORE has done the same with MAG, Crossref, Pubmed.

Semantic Scholar isn’t new , but until recently it only covered limited domains. But with the recent tie up with Microsoft Academic they now have increased their coverage from 40 million records to 175 million records , covering almost every domain.

Why consider Semantic Scholar as your search tool

Semantic Scholar has the name denotes, tries to use Machine Learning to derive semantic…

TL;DR — This articles shows you a reliable search strategy that you can use in Lens.org to find meta-analysis, systematic reviews, review articles of topics you are interested in regardless of your discipline to help kick start your research. I also do a comparison of this search strategy in Lens.org against Pubmed and show that this search strategy yields similar results, giving some assurance on the reliabilty of this method.

One of the techniques I teach new research students when starting a deep dive into a research area they are not familar with is to look out for review articles…
