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.

EL INDIVIDUO FRENTE A SU IDENTIDAD

León Grinberg

Se ha afirmado que el problema de la identidad ha sido considerado tan estratégico en nuestros tiempos, como lo era el de la sexualidad en la época de Freud [1].

Entiendo que antes de entrar a desarrollar los distintos aspectos de este problema, sería conveniente empezar por algo así como una definición del concepto de identidad. Lamentablemente, cuando me propuse intentarlo, me encontré frente a una complejidad mayor de la que esperaba. Y debo confesar que, en los últimos trabajos en que me dediqué a investigar este tema —que por otra parte me resultó apasionante—, no pude llegar a definirlo de una manera satisfactoria. Otros autores y psicoanalistas que se ocuparon últimamente de este concepto tropezaron con la misma dificultad.

Uno de los motivos del porqué este propósito se ha convertido en tarea tan ardua, reside en las dudas que despierta la ubicación precisa de su concepto. Por un lado, parece pertenecer al campo psicológico y al de la psicopatología; por el otro, al de la sociología y al filosófico.

Sin embargo, procuraré resumir y encuadrar sus principales características de acuerdo a las ideas de algunos investigadores y a las mías propias.

Por de pronto se ha señalado que la identidad, en su alcance más amplio, debe ser comprendida como una expresión elástica y funcional más que como un término de significación absoluta [17].
