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.

PROBLEMAS PSICOLOGICOS DE LA LACTANCIA

Marie Langer

Entre las funciones procreativas de la mujer, la lactancia juega un papel secundario, al punto que muchas mujeres se sustraen a ella. En la conocida obra de Beaumarchais, Fígaro dice, resentido, que la única molestia a que se someten los grandes señores en su vida es la de nacer. Idéntico comentario podría aplicarse, parafraseado, a ciertas grandes damas. La única molestia a la cual tienen que someterse, es la de dar a luz a sus hijos, abandonando ya su crianza a mujeres extrañas. Durante mucho tiempo se consideró indecoroso criar sus propios hijos, y aun al principio de nuestro siglo en muchos países europeos era de buen gusto tomar un ama de leche, pretendiéndose que así el lactante sería criado debidamente y no sufriría en su salud. Sin embargo sufría un daño indirecto, al faltarle el lazo afectivo que la crianza establece entre madre e hijo. En el inconsciente del niño criado por una nodriza mercenaria se establecen fácilmente dos imágenes distintas; la de una madre buena de su primera infancia —el ama de leche— en contraste con la de una mujer mala y frustradora, que es su madre real. Pero hoy no se suele recurrir al ama de cría, sino a la alimentación artificial. Gracias a nuestros progresos técnicos, ésta apenas perjudica físicamente al lactante. Si se prefiere con tanta frecuencia el alimento artificial a la leche materna, deben existir, además de causas sociales, razones psicológicas. Las sociales son evidentes; la mujer que trabaja fuera de su casa a menudo no puede dedicar a su hijo el tiempo necesario para criarlo durante varios meses, y desiste de su crianza, si no quiere o no puede renunciar a su profesión.
