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.

VINCULACIONES DE LA FANTASÍA DE REGRESIÓN INTRAUTERINA CON LA HIPOCONDRÍA Y LA PSICOPATÍA

Alberto Emilio Fontana

En un trabajo anterior [1], al presentar un caso de colitis ulcerosa, traté de demostrar, mediante el estudio del material aportado por una paciente durante su análisis, que la somatización era una forma de manejo de una psicosis que se controlaba en el cuerpo. Este control permitía mejorar la conexión con la realidad que, de otra manera, hubiera resultado perturbada por ansiedades persecutorias.

En esta ocasión, me ocuparé de otros aspectos que me han resultado muy evidentes durante el análisis de pacientes hipocondríacos y que pude aclarar, aplicando en todo momento la concepción de psicosis orgánica [2], a la cual ya me he referido.

Los nuevos aspectos que pude observar se hicieron manifiestos al considerar a la fantasía de regresión intrauterina como pivote en la comprensión de los dinamismos de la hipocondría, conceptuándola como defensa ante una conexión con la realidad temida.

Además, creo poder aclarar un aspecto señalado por todos los autores, que es la relación entre conflictos matrimoniales e hipocondrías crónicas y también la hipocondría directamente vinculada con la psicopatía, como si ésta fuera una manera diferente, maníaca, de resolver por la acción motora, un conflicto que hasta ese momento había estado confinado en el cuerpo, modificando el esquema corporal.
