Tip: Understanding Rank

PEP-Web Tip of the Day

When you do a search, you can sort the results bibliographically alphabetical or by “rank”. What is Rank?

Rank refers to the search engine’s “best guess” as to the relevance of the result to the search you specified. The exact method of ranking used varies a bit depending on the search. In its most basic level, when you specify a single search term, rank looks at the density of the matches for the word in the document, and how close to the beginning of the document they appear as a measure of importance to the paper’s topic. The documents with the most matches and where the term is deemed to have the most importance, have the highest “relevance” and are ranked first (presented first).

When you specify more than one term to appear anywhere in the article, the method is similar, but the search engine looks at how many of those terms appear, and how close together they appear, how close to the beginning of the document, and can even take into account the relative rarity of the search terms and their density in the retrieved file, where infrequent terms count more heavily than common terms.

To see a simple example of this, search for the words (not the phrase, so no quotes):

unconscious communications

Look at the density of matches in each document on the first page of the hits. Then go to the last page of matched documents, and observe the density of matches within the documents.

A more complex search illustrates this nicely with a single page and only 15 matches:

counter*tr* w/25 “liv* out” w/25 enact*

There are a lot of word forms and variants of the words (due to the * wildcards) above that can match, but the proximity (w/25) clause limits the potential for matching. What’s interesting here though is how easily you can see the match density decrease as you view down the short list.

The end result of selecting order by rank is that the search engine’s best “guess” as to which articles are more relevant appear higher on the list than less relevant articles.

Perspectives Following Klein and Bion on the Development of the Internal World: Clinical Implications

Kay M. Long, Ph.D., Lindsay Clarkson, M.D., Shelley Rockwell, Ph.D. and Lynne Zeavin, Psy.D.

Ed Tronick’s comprehensive theory of human development encompasses the psychological, neurobiological, and cultural to address how human beings make meaning. In addition to a large body of theoretical work and empirical studies, he has collaborated with Alexandra Harrison to develop a model of therapeutic process and change. In this article, we explore the divergences and convergences between Tronick’s theories about psychological development and psychotherapeutic process and those of Melanie Klein and Wilfred Bion. We organize our exploration around three areas of interest to both Tronick and Klein: (1) the development of levels of psychic organization, from primitive to organized; (2) the way in which experience is communicated and received across these different levels, and the kind of therapeutic listening necessary to discern this; and (3) the implications for therapeutic interventions that promote psychic change. We discuss Kate, the young patient Harrison and Tronick use to illustrate their model of psychic change, to explicate some differences and commonalities in the perspectives under consideration.
