Falling in love…

… with books.

Ever since I learned how to read, I loved it. There was something about that turning of the page, that dark text on paper, the curves of A to the sharpness of Z, as soon as I learned how it was the only thing I wanted to do. I was that awkward person in the corner of the party who would rather read about friendships than have them. That isn’t to say that I never had friends, I just tended to like my books a little bit better. My childhood was definitely one of a reading nerd.

All this is very well and good, right up until I started University. To jump topics, my very first day at Middlebury this summer my professor for Oral and Written Spanish said this about our coursework: “No es difícil, es mucho.” Now I’m not sure I agree; for one thing quantity preludes difficulty, but I digress. The thing about college is that there is so much to do, every second of every day there is a new experience, or at least an essay due at midnight and late-night cookie deliveries. I spent the eve of my 19th birthday writing an essay, and when I finished at 3am I went to brush my teeth and noticed the entire hall had signed a happy birthday poster that was written in Harry Potter font using a purple Sharpie.

In my cultures class at Middlebury we spoke about “La Movida Madrileña” and my professor quoted someone (I don’t remember who it was) saying that in Spain no one slept, because there was so much that they had the liberty to do once Franco’s regime had ended. Brandeis isn’t exactly recently-liberated Spain, but I still never sleep.

All this is to say, I am a busy individual. Reading, which got my whole life was an escape, somehow became a chore. As a Comparative Literature major with minors in creative writing and classical studies I’ve had to read a lot. Even my other major, linguistics, for all that it is a science has had a hefty amount of reading. Once I finish that Literature essay at 3 am the only thing I want to do is brush my teeth and sleep, not pick up another book.

Feeling this way hasn’t been comfortable to me, and for all that I enjoy college in that small way I haven’t been happy in the thing that I love.

Thankfully, my love in reading has been rekindled once more, but it’s not with Harry Potter this time, it’s with Isabel Allende. The book was “Eva Luna” (in the original Spanish of course; I wasn’t allowed English this summer) that reminded me that reading is fun and I’m happy to have had my experience at Middlebury, because I’ve fallen in love with reading again, and that’s wonderful.

Precision, Recall, and Inclusivity

[This is a guest post by Talia’s girlfriend Annie, who is maintaining this blog while Talia is away at Middlbury Language Schools]

In my last post on here I mentioned that my job involves writing programs that identify important information from text documents. When testing these programs, there are two main ways of evaluating the accuracy of their output: precision and recall. Put simply, precision refers to what fraction of the retrieved information is relevant to what we’re looking for, while recall refers to what fraction of the relevant information in the original text is retrieved by the program. Ideally, one would want a program to have both high precision and high recall – that is, for it to return most or all of the information the user is looking for and little or no irrelevant information – but this isn’t always possible. More realistically, you’ll often face a tradeoff between precision and recall. You can optimize for precision, and make sure that everything in your output is the sort of thing the user is looking for, but then you run the risk of overlooking other information that might be slightly less obviously relevant, but still within the scope of the user’s query. You can optimize for recall, and make sure to return every piece of information that could possibly be relevant, but then there’s the chance you’ll also turn up a lot of junk data along with the useful stuff. Or you can try to strike a balance between precision and recall, getting each one high enough to be useful without sacrificing the other.

Which of these evaluation metrics is most important depends on what task a program is intended to accomplish, and what the end user’s particular needs are. For instance, suppose you’re writing a program to automatically filter out offensive content on social media. (Some of my classmates and I wrote a program like this for a class project once, although it didn’t end up working very well.) If a social media company is going to be using your program as the first line of moderation for everything that gets posted on their platform, you likely don’t want it to become a heavy-handed censor. In this case you’ll probably want to err on the side of optimizing for precision, filtering out only the things that are well and truly beyond the pale and letting human moderators make the call on the edge cases. On the other hand, if this program is intended as an optional add-on that users of a social media platform can choose to enable, you’ll probably want to err on the side of optimizing for recall. The people who are likeliest to use such an add-on tend to have a very strong need to filter out certain content – say, people with anxiety or trauma who are trying to avoid seeing content that is triggering for them – so you want to make sure all of this content gets filtered, even if that means blocking some harmless stuff as well. High precision isn’t inherently better than high recall, or vice versa; it all depends on the specific goal you’re trying to achieve.

I’m now going to completely switch gears for a minute and move from this relatively dry, technical subject to one with much more emotional heft: inclusivity in the LGBTQ+ community. (I’m focusing on this community because I’m a part of it, but I doubt it’s the only community this discussion will be relevant for.) If you’ve spent any time discussing LGBTQ+ politics – especially on the internet, where political discourse is a full-contact sport – you’re no doubt aware of the frequent heated debates about where exactly to draw the boundaries of this community. For instance, I once saw a post on Facebook proposing the acronym SAGA (Sexuality And Gender Acceptance) as an alternative term to LGBTQ+ that could include everyone without making the acronym cumbersomely long, and one of the comments was arguing against this idea, pointing out that such imprecise wording could allow kinky straight people to elbow their way into the community. Or on a more serious note, back in June when Pride was going on, I saw rather a lot of posts on Tumblr arguing about whether asexuals should be included in Pride, with several people arguing that asexuals hadn’t experienced the same oppression that gay, lesbian, bi, and trans people had, and so Pride wasn’t for them.


When I come across arguments like this, all I can think is: this is clearly a situation in which recall matters a whole lot more than precision. Remember how I said that whether it’s better to optimize for recall or precision depends on your particular goal? Well, what is the goal of building an LGBTQ+ community? There are obviously many goals, but as far as I’m concerned, the primary goal is to provide a space for people who are marginalized by the heteronormativity and cissexism of mainstream culture, where they can be safe and free to live their authentic lives, and where they find the support and solidarity they need in order to overcome the obstacles that the rest of society has placed in their way.

Personally, I care much more about making sure that everyone who needs such a space has access to it than I do about keeping out people who don’t meet some set of entry requirements. Sure, there might be a few straight kinksters who will see inclusive language around sexuality and assume it’s talking about them, but there are also countless queer kids who are just figuring out their sexuality or gender and aren’t sure what label – if any – to claim. Don’t we want them to know they have a place in our community, even if they don’t have the precise words for what they are yet?

For every asexual person who doesn’t face much discrimination for their orientation, there’s another one who’s facing ostracism from their family for rejecting their “sacred duty” of getting married and having children. Don’t they need our love and support too? By focusing on precision instead of recall – that is, focusing on who we need to exclude instead of who we need to include – we run the risk of pushing away some of the people who our community could do the most good for.

In other words, when the machine revolution comes and our new robot overlords implement Fully Automated Luxury Gay Space Communism, I know what sort of information retrieval algorithms I want them to be running.
