📙 Cochrane Reviews

The implementation of Cochrane aims to provide all "Cochrane Reviews" papers to our customers in the most compliant and user-friendly way possible. To achieve this, Flinn has developed a partnership with the Cochrane Library organization. 

Data availability:

1. Data exhaustiveness: Flinn ensures the full data exhaustiveness for the date frame 2014 - 2024+

2. Data origin control: The literature data has been obtained through the official John Wiley & Sons Corporation, holder of the Cochrane library.

3. Relevant official data :

   id	cochraneid	source	published_date	title
   authors	affiliations	publication type	doi	journal
   labels	abstract	summary	mesh headings	mesh words
   languages	link	plain language summary

4. Data Accessibility: 24/7 accessibility

   1. Our storing and searching system ensures that even though Cochrane is offline, our customers can still access the data through Flinn.

5. Consistency of data

   • Flinn ensures daily data updates with the official Wiley data set to update any differences.

Search logic:

Based on many inputs from our customers, we have decided to create a Flinn specific search engine for Cochrane, which aims for higher quality of matches, better transparency with an exact term logic. 

1. Flinn search engine: We have chosen the state-of-the-art technology Elastic search developed by Elasticsearch B.V:

   1. All data fields are searchable (listed in Relevant official data)
   2. Exact term matching
      1. To ensures maximum relevancy of hits we apply by default: No truncation, No fuzziness, no wild card.
         1. Our customers can however use wildcard or fuzzy operators by themselves
   • Default ‘AND’ system between words to ensure minimum false positive.

2. Date filtering: Flinn guarantees an inclusive start date & end date selection

3. Flexible boolean search options: We have designed our search engine to deal with any boolean operators such as OR, AND, NOT; (), *, ^etc…

4. Flinn operators: We have developed and validated Flinn specific operators to support our customers:

   AUTHOR: (name)	A specific author name that must be found.
   TITLE/ABSTRACT: (value)	Use this operator to search your keyword only in the papers' title and abstract (incl. the ‘plain language summary’). All other information section will be ignored for the search.
   TITLE: (value)	Words and numbers included in the title of a citation, as well as the collection title for book citations.
   PUBLICATIONTYPE: (type)	Specify a precise article type that must be found or excluded. Available filters: "Systematic Review" "Diagnostic Review" "Intervention Review"
   MESHTOPIC: (topic)	Use this operator to search your keyword only in the main medical topics of the paper. All other information section will be ignored for the search.
   AFFILIATION: (value)	Affiliation may be included for authors, corporate authors and investigators, if submitted by the publisher. Searching for terms in the affiliation field searches in all author affiliations on a citation.
   JOURNAL_NAME: (name)	The journal search field includes the journal title abbreviation, full journal title, or ISSN/eISSN number.
   LANGUAGE: (language)	The language search field allows you to filter articles by the language in which they were published.
   MESH_TERMS OR
   MESH_SUBHEADING	MeSH terms to help describe more completely a particular aspect of a subject.
   PUBLISHER: (name)	Includes publisher names for Bookshelf citations.

Getting the same results in Flinn as in Cochrane (Title/Abstract search):

With our Flinn search we aim to provide a clear, transparent and specific search logic, to present our customers only the relevant results with a high degree of traceability for each result. However, for some users, it's important to reconcile the search results in Flinn and Cochrane. Hence, we have aligned the Title/Abstract search so that it yields the same amount of results. In order to get the same results in Flinn and Cochrane, please apply the following search settings:  

• In Cochrane, you need to search in the fields of Title OR Abstract in the advanced search manager (see screenshot below).

Moreover, the search word variations need to be disabled. (This functionality expands the search to many widely related categories resulting in many irrelevant results).

Search settings in Cochrane

• In Flinn, use the TITLE/ABSTRACT: (value) Operator and insert your search string between the parenthesis. Moreover, be sure to always use operators between each word to avoid any unintended search behavior. An example of a search string would be: TITLE/ABSTRACT: (treatment AND during AND pregnancy)

  

Full-text availability:

1. Open Access papers on Flinn: Flinn partnered with MIRA.Digital GmbH to provide to our customers all Open Access papers and links for most paid articles
2. Full-text data: Flinn does not include the text inside OA PDFs for the search engine to avoid mismatches with poor data quality contained in journal names, bibliography, affiliations etc..)

Deduplication with PubMed:

1. Validated deduplication: Aligned with customers needs, Flinn offers a validated and automated deduplication detection between PubMed and Cochrane results.
   1. Since 99% of Cochrane is present on PubMed, this ensures minimum effort to identify those duplicates
