ScienceDirect October 2007 release
Functionality
The following functionality was implemented on ScienceDirect on 20 October.
• Related Articles
What?
An automatically appearing list of relevant articles on every article page in ScienceDirect. Related Articles will enable the display of articles that are highly related to the source article. This new functionality will be placed on pages with search results, table of contents, and on the article page. Through intelligent document matching, Related Articles will automatically display citation information and the abstract – including a link to the full text – of content relevant to the article being accessed.
Why?
Related Articles will improve the discoverability of information and make it easier for a researcher to find key information. This new functionality will also encourage greater use and exploitation of the wealth of information on ScienceDirect.
How does Related Articles work?
- The entire document is processed and key terms are extracted.
- The terms are weighted with regard to frequency of occurrence and placement in article, and matched against a database.
- The resulting vector *, which is essentially a complex search query, is run against other documents and the result is a list of documents ranked by similarity.
Note: Related Articles does NOT produce articles others have viewed or purchased together!
* Vectors are a kind of document signature (word-weight pairs) representing a document's content in a way that allows comparison between documents. It is the numerical representation of the unstructured textual content of a document. Vectors can be used to enable clustering and refinement operations.
What?
The spell checker will recognize spelling errors using a built-in dictionary. For example, if a customer enters “heat attack” the spell checker will ask if the customer intended to search for “heart attack”, for which there is a much larger results yield on ScienceDirect.
Why?
The spell checker will give the researcher more time to spend on actual research because they won’t have to re-enter information.
What?
Graphical Abstracts are images that summarize the scope of a paper much more succinctly than plain text. Graphical Abstracts will become more visible for all customers in chemistry journals on ScienceDirect. In Chemistry journals, Graphical Abstracts are usually images of structures or reactions. Initially there are 21 titles that contain Graphical Abstracts and an additional 30 titles will have them added shortly.
Graphical Abstracts will appear as the default display when browsing a table of contents from one of these journals on the journal homepage. On the search results the default display is the Article List with Full Abstracts or Graphical Abstracts as alternative display options.
Why?
Graphical Abstracts enable researchers to cover a larger range of content because they can see at a glance what a given article is about.
