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.

Salieri's Dilemma: A counterpoint between envy and appreciation Language Translation

R. Horacio Etchegoyen and Clara R. Nemas

Taking as its starting point Klein's concepts of 1957, this paper stresses certain characteristics of envy that have not yet been taken into account in psychoanalysis. Klein described the conflict between envy and gratitude as inherent in the human being; she suggested an interesting link between envy and admiration, but never developed this idea in her theory. The hypothesis that we put forward in this paper is the existence of a particular intolerance—related to envy—of one's own capacity to recognise the valuable aspects of the object. This situation leads to the paradox that the same faculty that allows the patient to appreciate the good qualities of the object is at the same time the source of unbearable pain. The capacity to recognise the good aspects of the object—whether they are perceived or attributed by projective identification—cannot be accepted as a valuable aspect of the self and is taken as a proof of the self's unworthiness. We think that the description of this intolerance towards admirative appreciation introduces a change in the understanding of idealisation simply as a defence against envy and enriches the conflict expressed in the immediacy of the transferencecountertransference.
