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.

Psychoanalytic Aspects of Religious Experience

W. W. Meissner, S.J.

Introduction

From virtually the beginning of its intellectual history, psychoanalysis had an implicit intention to extend itself to the broadest ranges of human experience and culture. Even as early as 1895, in a letter to Fliess, Freud (1887-1902) wrote:

I am plagued with two ambitions: to see how the theory of mental functioning takes place if quantitative considerations, a sort of economics of nerve-force, are introduced into it; and secondly, to extract from psycho-pathology what may be of benefit to normal psychology. Actually a satisfactory general theory of neuropsychotic disturbances is impossible if it cannot be brought into association with clear assumptions about normal mental processes [pp. 119-120].

It has always been somewhat enigmatic that the psychoanalytic attempt to bring understanding to one of mankind's broadest and farthest-reaching areas of experience, that of human religious phenomena, has continued to be relatively inadequate and impoverished. It is not difficult to find reasons for this, particularly for Freud's own religious, or if your prefer anti-religious bias. A combination of sociological, ethnic, and historical circumstances has contributed to the prolongation of this relative impoverishment.
