||
<p>This cyber/technofeminist cross-reader does not follow one but two axes, bridging the act of reading a collection of texts, with the act of reading a tool.</p>
|
||
|
||
<p>These cross-readings connect ...</p>
|
||
<p class="tfidf">... the <em>Term Frequency Inverse Document Frequency</em> algorithm, or <em>TF-IDF</em> in short</p>
|
||
<p class="techfem">... a collection of <em>cyber- and technofeminist manifestos</em></p>
|
||
|
||
<p class="tfidf">The TF-IDF is a commonly used algorithm to find the most important words of a document. The algorithm is (partly) written by the female computer scientist Karen Spärck Jones in the 1970s and has become one of the important algorithms of many search tools online, such as digital library systems or corporate search engines like Yandex or Google. The algorithm turns written documents into a sorted lists of search results, using a specific relative and inversed way of counting, that is sensitive for contrast in written documents. </p>
|
||
|
||
<p class="techfem">The cyber/technofeminist manifestos connect feminist thinking to technology, introducing feminist servers, cyborg figures, cyberwitches, or pleas for the glitch as cultural digital artefact. This collection, which is obviously incomplete, brings a diverse set of technofeminist documents together that are published between 1912 and 2019. The manifestos speak about very different concerns and questions, but they connect in terms of energy level. Urging to make a statement, ready to activate.
|
||
<br><br>
|
||
An interesting note to mention: Karen Spärck Jones was an advocate for the position of women in computing. <em>“I’ve been trying to think a little bit—but it’s very dispiriting!—about how to try to get more women into computer science. On the whole, everybody who thinks about this is depressed, because we’re going backwards rather than forwards.”</em> <sup><a href="https://ethw.org/Oral-History:Karen_Sp%C3%A4rck_Jones#On_Getting_More_Women_into_Computer_Science">•</a></sup></p>
|
||
|
||
<p>These two axes, the algorithm and the manifestos, interoperate. They support and strengthen eachother as the X and Y of this cross-reading tool. </p>
|
||
|
||
<p>The TF-IDF algorithm, while responding to a search request, creates cross-readings through the manifestos. It outputs a list of search results around the subject of search, creating a field of statements, questions and concerns around one single word. Meanwhile, the algorithm starts to interoperate with the manifesto as a format. Sensitive as it is for bulletpointed writing, repetition and unique words -- elements that are used a lot in these statement driven documents. The algorithm prioritizes higher contrastful language over academic writing, repetition over very diverse vocabularies and the use of unique words over the use of common ones.</p>
|
||
|
||
<p>See this cross-reading tool as an exercise in reading, across a field of technofeminist thinking and a tool for algorithmic sorting.</p>
|
||
|
||
<!-- <p>Reading the TF-IDF algorithm by itself only results in a technical understanding of this old artefact.</p> -->
|
||
<!-- <p>This algorithm thereby connects a discrete procedure (that of computing) to a very vivid and strong document format: the manifesto.</p> -->

|

# Term Frequency<br />
|

tf_count = 0<br />
|

for word in words:<br />
|

if query == word:<br />
|

tf = tf_count/len(words)<br />

idf_count = 0<br />
|

|

if query in words:<br />
|
||
idf_count += 1<br />
|
||
<br />
|
||
tfidf_value = tf * idf<br />
|
||
<br />
|
||
return tf_count, tf_count, tfidf_value
|
||
</code>
|
||
<br><br>
|
||
The TF-IDF algorithm, shown above in the programming language Python, weaves a layer of contrast into the text. Not literally, but in the form of numbers. The most contrastful words are those that the algorithm consideres as the most specific words for that text.
|
||
<br><br>
|
||
The TF-IDF values are calculated in two steps. The algorithm first counts the <em>Term Frequency</em> (TF) by counting the appearance of a word in the text, relatively to the total number of words in the document. This way of relative frequency counting makes it possible to compare wordcounts between documents with variating lengths. This makes it possible to compare Donna Harraway's long essay <em><em>A Cyborg Manifesto</em></em> (1984) with the relatively short text of <em><em>The Call for Feminist Data</em></em> written by Caroline Sinders (2018).
|
||
<br><br>
|
||
In the second step, the algorithm counts relatively against all the other documents in the same dataset, using the <em>Inversed Document Frequency</em> (IDF). This part of the algorithm, which is Karen Spärck Jones’ addition, introduced a subtle form of inversed relative counting throughout all the documents in the dataset. Instead of just counting word-frequency in one document, Karen proposed to count in a relative inter-document way.
|
||
<br><br>
|
||
This means that when a word only appears in one or a few documents, that its value is greatly enlarged. The concequence being that words as <em><em>the</em></em> or <em><em>it</em></em> will be given a very low number, as they appear in all the documents. And specific words, such as <em>paranodal</em> in <em>A Feminist Server Manifesto</em>, will get a very high value as this word is only used 4 times in the whole dataset and all of those 4 occurances where in this manifesto.
|
||
<br><br>
|
||
Another example is <em>SCUM</em>. Although the word <em>SCUM</em> is not the most commonly used word in the <em>S.C.U.M. Manifesto</em>, it is the word that gets the highest score: relative to all the other manifesto's, <em>SCUM</em> is mostly used in this manifesto. This increases the score a lot.

<p class="tfidf">The algorithm introduces the idea of a <em>context specific way</em> of counting words.
|
||
<br />
|
||
<br />
|
||
Karen's IDF part of the TF-IDF algorithm creates an ecosystem where the resulting numbers heavily depend on the presence of the other words. The deletion or addition of a document would change all the interrelations in the dataset, as the calculations fully depend on each other. Altough the practice of algorithmic text processing is inherently pretty brutal, as language is regarded as nothing but a <em>bag-of-words</em>, the TF-IDF algorithm and its algorithmic character, give us a way of counting that creates situated datasets where values are determined by their self-created context.
