Welcoming 2017 and My 2016 in Review

A little bit late, but… hello, 2017! ūüôā

I’ve planned and started¬†two commitments for this year. The first one…

The second one is something that I actually started 3 years ago, yes, to master German (with Duolingo)! I’m going to start a stickK commitment soon, after a paper deadline. It seems to be an interesting concept, a friend has tried and recommended¬†it. The idea is: you set your goals, then¬†you can set a referee who verifies your reports. You can also¬†(optionally) set the stakes, in which the money can go to either a friend or foe, charity, or anti-charity, if you fail your commitment. Let’s see how it goes ūüėČ

As for my 2016 in review, inspired by a friend who reviewed his year by embedding¬†the highlight of his tweets for each month, I’m going to do the same! But I don’t tweet anymore, so I’ll embed my Facebook posts instead.

TL;DR: 2016 was a great and hectic but exciting year for me. A year of change and transition. I finished my PhD. I went home for 2,5 weeks. I started a Postdoc position, moved to Germany. I went to Japan for the first time, went back again two months later. And finally I turned 30.

Now, let’s start with…

Keep Pushing (the Boundary)

I was re-organizing my bookmarks the other day, which were¬†just a collection of links that I found interesting… at some point in my life. Some of them can’t even be opened¬†anymore.

Anyway, I found this one that is actually quite relevant with my situation now:

Matt Might, a professor in Computer Science at the University of Utah, created The Illustrated Guide to a Ph.D. to explain what a Ph.D. is to new and aspiring graduate students. [Matt has licensed the guide for sharing with special terms under the Creative Commons license.]

Reminding me how little my ‘contribution to knowledge’ is and to not forgetting¬†the big picture. So yeah… let’s keep on pushing! ūüôā

So… What’s up?

It has been 5 months since the last time I wrote here. What has happened since then? A lot!

First and foremost, I’ve finally finished my PhD! ūüėÄ This was probably the main reason why I’d been neglecting my blog for so long. The first three months of this year I was basically in a frenzy of thesis writing, experiments, paper writing and… job hunting. After the thesis was submitted on March 25, the madness still continued with preparations for the PhD defense: making presentation slides, hosting my sister and cousin—who came to give supports on the D day, thanks a lot, Dita and Dhika! :*— and arranging graduation parties. Finally, the D(efense) day was April 12, on which I was declared as Dr. Paramita Paramita! ūüôā

This was followed by another frenzy of post-doc position hunting, sending CV here and there, and a series of interviews (onsite and¬†online). Considering the options for the future was also giving me headache. Anyway, I’ve picked one that I believe to be the best for now, let’s see…

Life was definitely much more relaxed in May, but… my domain paramitopia.com was expired, and the website¬†where I registered this domain doesn’t¬†offer an easy way to pay the renewal fee :(. So, I will definitely¬†change the domain registrar. In the meantime, I bought another domain paramitamirza.com, which sounds more professional ;). I plan to host my academic/professional profile—publications, research activities, research output, etc.— in this domain, along with my blog. For now, only the blog is set up, but¬†at least I can start writing blog post again.

And now it’s June already!

I will try my best to fill this blog again with things happened during those 5 months¬†hiatus. Stay tuned! ūüėČ

Singapore for Summer

I’m in Singapore!

And I’m going to be here for the whole summer, 3 months to be exact, for some kind of an¬†internship at the National University of Singapore (NUS). Working on what? Of course… deep learning, baby! ūüėÄ

Well, at least… working on an attempt to solve my research problems using deep learning, because¬†it has become¬†the buzzword of today’s NLP research. Yeah, that’s it.

I actually arrived 2 weeks ago, but only recently I finally get myself settled at¬†my new office, with PC and cards: (from up to bottom) ez-link card for easy payment *for¬†bus, MRT/LRT, swimming pool, printing, and I don’t know what else, probably many more*, NUS access card to get inside my office *even to get inside the room I need this card*, and lastly… my TEP card,¬†which allows me to freely enter/exit Singapore during these 3 months.

I haven’t met my advisor yet, because he was still out of office¬†until this week. So maybe next week. But I’ve met some of the colleagues from the group.

Enough about the working part, now… what can I do during my free time? Singapore is boring, some people said ;), but I’ve checked¬†this list of 50 things to do in Singapore and 52 things to do in Singapore before you die, and come up with my own list, 15 things I want to do in Singapore:

  1. Go trekking: Bukit Timah Nature Reserve, MacRitchie Treetop Walk and along the (defunct) KTM railway track.
  2. Go rock climbing at Dairy Farm, Singapore’s only natural outdoor rock climbing
  3. Cycling at the East Coast Park
  4. Cycling in Pulau Ubin and Chek Jawa
  5. Re-connect with mother nature at Sungei Buloh
  6. Have a picnic at the Botanical Gardens
  7. Feel on top of Singapore at the Marina Bay Sands Skypark
  8. Have a party at the Singapore 50th birthday
  9. Visit a Public Swimming Complex
  10. Visit Sentosa island and Universal Studios Singapore
  11. Visit Haw Par Villa
  12. Take on an escape room challenge
  13. Cultural tours around Chinatown, Little India and Kampong Glam, plus food tasting
  14. Shop till drop at the Great Singapore Sale
  15. Get trackside at the Singapore F1 Grand Prix ‚Äď vroom vroom *this year it will start on 18th of September, which is exactly the last day of my internship :D*

Some of them I can do by myself, but for some others I need companions :(. So, come here, dear friends! and family *adeeek, ayo sini sini*! and bear! Let’s have some fun in Singapore ūüôā

IndoTimex for Indonesian Temporal Expressions

One question that got me thinking during the interviews with Google¬†was, “Do you have any experience in building an NLP tool, like a tagger or a parser, for Indonesian language?”, and my answer was, “Well, ehem, not yet.” ¬†I wonder why…

That’s why, during the last Christmas/New Year break *while waiting for the result of the interviews*, I decided to do something for Indonesian language :”>. Actually, almost the same thing I already did for Italian… building an automatic extraction system for Indonesian temporal expressions!

Extraction means recognizing time¬†expressions given a text, then normalize their values. For example, if today’s date is March 25, 2015 (2015-03-25), then when the system found dua hari yang lalu [two days ago] the value will be normalized as 2015-03-23. I called the system: IndoTimex!

The online demo of IndoTimex is available here.

The complete system, implemented in Python, is available (for download) here.

And… since there was a conference deadline around that time, PACLING 2015 *which will be held in Bali! :D*, I submitted a paper about it and got accepted. So, to know more about the technology behind the system, please read the paper here.

If everything works fine, soon I will visit Bali (and definitely, also home) for a vacation with my family, oh, and also for the conference ;). This is what we call¬†as¬†an Indonesian proverb “sambil menyelam minum air”, hohoho…

Of A Very Shiny Crystal Ball Called Google (Part 2)


Z√ľrichsee, from Arboretum, a small park at the very top of the lake

Exactly one day after I published this blog post here, a recruiter from Google contacted me, saying that there is an open position fitting my profile:

Analytical Linguist, NLU in Machine Intelligence (Thai and Indonesian)

Understanding natural language is at the core of Google’s¬†technologies. The Natural Language Understanding (NLU) team¬†in Google Research guides, builds, and innovates¬†methodologies around semantic analysis and representation,¬†syntactic parsing and realization, morphology and lexicon¬†development. Our work directly impacts Conversational Search¬†in Google Now, the Knowledge Graph, and Google Translate, as¬†well as other Machine Intelligence research.

As an Analytical Linguist, you will collaborate with Researchers and Engineers in NLU/Machine Intelligence to achieve high quality data that improves our ability to understand and generate natural language systems. To this end, you will also be managing a team of junior linguists and vendors to derive linguistic databases as well as propose direction for approaches to language specific problems.

Target languages: Thai and Indonesian

My first reaction was… amazed. How come, just right after I posted a writing about my epic failure at the previous interview?? ūüėÄ What amazed me even more was that this opportunity answered my question back then, quoted exactly as it is: “what else could be the¬†reason to work at Google other than having something ‚Äėshiny‚Äô in your CV? :p”

Of A Very Shiny Crystal Ball Called Google

Imagine this feeling. You have this very shiny crystal ball on your hands, and you can’t wait to put it safely on a shelf, so you can show it off to everyone. However, it’s reaaally heavy, and it took a lot of effort and carefulness to place it safely on the shelf. Just when you think you’re really close, you somehow let it go. You stumbled, or your hands just gave up because it’s too heavy. It then fell and broke into pieces.

That’s exactly what I felt last weekend.

When someone from Google contacted me, asking whether I will be interested to do a summer internship there next year, working with him, I was ecstatic. I met this guy in a conference, and luckily he was quite interested with my research. I’ve been trying to get an internship position there *well, actually anywhere, big companies are preferable though ;)* since last year, but without knowing anyone that could recommend me, it’s hardly possible to even get an interview.

Reading the email, I was jumping around like crazy. It was my boyfriend who brought me back to the ground, saying this doesn’t mean that I will go for an internship there. He’s right. The guy confirmed it. I still have to go through the regular protocol, including passing the dreadful technical interview. So this is like my ticket, not for the internship itself, but for a chance to get one.

I got two phone interviews scheduled three weeks after that, 45 minutes each. The first one was purely technical, live coding on a Google Doc. The second one was more focused on the research I am doing. The first interview was more terrifying than the second one. Talking about my own research was easier than solving a random coding problem, no matter how basic it is :p. Before the interviews I was studying like crazy, recalling all the basics about data structures and algorithms, practicing on Topcoder, reading all the tips and tricks. On the day of the first interview, I thought I was ready, or maybe more like I was trying to convince myself that I was ready. It turned out no, I was certainly not.

The Story of Tim and Casey

Tim and Casey are best buddies since high school. One day, after years, they meet up in a bar for some drinks, sharing their work life stories, cursing at their bosses ;). They’re working at a company named McRels Inc. It turns out that their jobs are very similar. Both of them are working with text, news to be exact. Tim’s main responsibility is reading news,¬†then¬†ordering every events happening in the news in a timeline, guessing whether an event comes after or before another event. Casey started working on his current job just recently. His job is to decide whether there is a causality between two events.

Tim: “So, when I am given a text Typhoon Haiyan struck the eastern Philippines on Friday, killing thousands of people, I should be able to guess that the¬†struck happens before the¬†killing.”
Casey: “Aaah, I see… For me, I must decide whether the¬†struck caused the killing or not.”

Casey’s job seems to be easier since the decision is binary: yes or no (well, also to decide which one is the cause and which one is the effect), but it’s actually much more difficult than Tim’s. One reason is that, unlike Tim, Casey doesn’t have enough resources to learn how to decide on the causality. Moreover, the concept of causality is more abstract than temporal ordering.

Tim is very lucky, because he could participate in a challenge on guessing the event ordering. As we know, competition can lead people to perform their best‚ÄĒthat is, it can improve their quality of performance.[1]¬†Unfortunately, Casey doesn’t get that chance.

First of all, Casey needs to build resources for learning on deciding the causality between events, so he hires minions to do that. He can only afford two minions since he’s low on budget.

The minions are not so smart, so he needs to set up guidelines for them to annotate causal information in text.[2] Tim offers him to use his available resources, which is a collection of text already annotated with all events available in the text. Having the resources annotated with causal information, Casey can finally learn how to identify causality between events in text.[3]

Since in theory, causality has a temporal constraint, that the cause happens before the effect, Tim and Casey have an idea to cooperate in order to improve their learning abilities. There still need to be some discussions for this idea, involving more meetings in a bar… with a lot of drinks, I suppose :).

P.S.: in case you don’t get the metaphors, this story is basically my PhD topic,[4] where Tim and Casey are automatic systems for extracting temporal and causal relations, respectively. And the two minions are actually me and my advisor :D.

Updates on PhD Life

picture is taken from PhD Comics

In order to be consistent with ‘one blogpost per month’ this year *damn, I was more productive back then…*, I will just write some updates on my PhD life, which is going quite well. I’m halfway through my second year now, and I can say.. I’m back on track, after being a bit lost during the first year :).

#1 Qualifying exam… passed!


PhD Research Proposal – Qualifying Exam from Paramita Mirza

I passed the exam before Christmas holiday started last year, leaving me in a super relaxed mood during the holiday :). Out of the three members of the commission, only one of them was active in the discussion, maybe because she was not so far related to the topic. Almost all of them agree that this was too much as one single PhD topic, someone said I could produce 3 PhDs with it :D. Well, a bit ambitious plan is fine I guess :p.

#2 Work hard, travel hard!
