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.

Conferenza annuale di psicologia del sé Toronto 28-31 ottobre 1993

Franco Paparo

La conferenza annuale di psicologia del sé, svoltasi a Toronto dal 28 al 31 ottobre 1993, era la sedicesima. Heinz Kohut ha partecipato soltanto alle prime (Chicago, Boston, Berkeley). Dopo la sua morte, il gruppo dei suoi allievi e collaboratori, costituitosi in un National Council for Psychoanalytic Self Psychology, ha continuato la tradizione coinvolgendo nell'organizzazione, di volta in volta, le istituzioni psicoanalitiche della città in cui il congresso si svolge. Questa volta tra gli sponsor figuravano sia la Toronto Psychoanalytic Society che il Toronto Institute of Psychoanalysis.

La conferenza che, in accordo con la tradizione, prevedeva un inizio nel primo pomeriggio del venerdì ed una conclusione nella mattinata della domenica, era dedicata alle “Sfide cliniche e teoriche”, ed il programma era articolato in tre sedute plenarie: “Innovazioni nella teoria e nella pratica”, “Un dialogo clinico” e “Nuove prospettive sul controtransfert”.

La discussione dei temi, presentati nelle sedute plenarie, è stata svolta, come sempre, in piccoli gruppi presieduti dai membri del National Council, della durata di circa due ore.
