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:
Angel Garma

Varios autores sugieren que los sueños se perciben primeramente en color y que este color paulatinamente va desapareciendo en el recuerdo. Goolker afirma que la presencia de color es poco frecuente en las pesadillas, lo que contradice la opinión de que dicha falta de color es debida a la disminución de afectos.

Yazmajian encuentra que los sueños completamente coloreados son representaciones enmascaradas de los de órganos y de partes corporales nunca visualizados, como la región más profunda de la vagina, los testículos (?) o las visceras. Los mecanismos de este tipo de sueños son el de un cambio en su contrario y el de la proyección: el órgano o la parte corporal no visible aparece en los sueños como supervisible y como externo mediante el uso intenso de color.

A pesar de que en la literatura se insiste en la correlación entre afectividad y color en los sueños, según Yazmajian en este tipo de sueños el color es empleado por el Yo durante el soñar de un modo controlado, integrado y hábil, aun en aquellos casos en que existen asociados afectos intensos.

En el presente artículo Yazmajian no menciona la investigación del autor de esta reseña sobre los colores en los sueños como simbolizadores de contenidos anal excrementicios. Sin embargo, en los dos casos por él expuestos hay mucho material confirmatorio de esta última interpretación.
