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.

Review by:
Carlos M. Martínez

El contenido principal de este libro lo constituye el desarrollo de las ideas y hallazgos del autor con respecto a una fantasía: (o un grupo de ellas), “la fantasía de nacimiento”, considerada como la clave para la comprensión y explicación de las motivaciones de todo producto psíquico.

En la dinámica de la vida psíquica señala Abadi la existencia de tres roles fundamentales —paterno, materno y filial— a los que pueden, en último término, reducirse todo rol. Estas denominaciones provienen de tomar en consideración las funciones, actitudes, ansiedades, etc., de padre, madre e hijo en relación con el nacimiento.

Considera el autor que todas las ansiedades —teniendo siempre como fondo la ansiedad ante la muerte— pueden ser referidas a tres modos fundamentales: ansiedad ante el encierro en el adentro, ante el cambio, ante el afuera sin límites; y corresponden a tres momentos sucesivos: encierro en el útero, pasaje por el canal del parto, momento inmediatamente posterior al nacimiento.

Las vicisitudes de esos tres personajes en estos tres momentos configuran las distintas fantasías inconscientes subyacentes a la conducta. El personaje principal es el hijo, representante de lo más auténticamente humano (o yoico), éste es el motivo de que su historia sea la más ampliamente considerada.

Luego de exponer el autor la interpretación dada por Freud al mito de Edipo, y de afirmar su innegable validez, sostiene la existencia de otros significados que pueden ser descubiertos retrotrayendo el conflicto triangular al momento del nacimiento.
