The Hawker Center

(Editor’s note: this is an old post by Min from the SIGIR ‘08 blog, but still relevant today).

While Singaporeans are well renowned for their attention to detail, this carries on most distinctly in food. Yes, Singaporeans are especially proud (read: finicky) of their local food sources. No trip to Singapore is complete without a trip to a local culinary institution, the hawker stand.

There are many food stands here, gathered into “food courts” (air conditioned centers or hawker centers: open air plazas. What we’re after here is the hawker center. Why hawkers? Well, they are called hawker centers, named after the hawkers (callers) who used to go around the neighborhood crying out to advertise the food that they had to offer (”get your fresh fishball noodles here!!”). In more recent times these mobile food vendors were legislated and localized to a specific food stall for inspection purposes, among other things. Each center consists usually of about 15-50 stalls (although usually many fewer will be actually open) offering various Chinese, Indian, Muslim and occasionally other foods, such as Japanese, vegetarian or Italian. Within each plaza there is always a central stand serving drinks (thus you buy your beverages at a different stall), which sometimes doubles as a fresh fruit stand (because many of the beverages are freshly squeezed/pulped fruit juices). There are many variants of Chinese food that I didn’t recognize here when I first arrived in SG and for the most part I have been ordering what I can pronounce reasonably ok (it’s easier to use English and you probably sound less like you’re trying hard if you do). Also, family is a big thing here. There are practically no single people eating at these plazas, unlike the food courts of the US. Mostly families or friends or couples going out. The price of food at these hawker stands is also very cheap. Your average dinner at the food plazas will be around 6 SGD (4 USD), although our local school’s canteen, you might be hard pressed to spend more than 4 dollars for a regular meal. Eating times vary a bit from other global metropolises, where it is always possible to get a meal 24 hours a day. That can be done easily in Singapore too, but just in certain areas (ask me!). I find the hawker food good to eat and sometimes have a hard time in justifying the difference in cost to eat at an actual restaurant (the cost is about 15-20 SGD or much more), since the hawker food is already quite good for my taste.

Hawker food comes in many different varieties but there are some simple rules to remember about eating out:

- Bring tissues. Those small packs of tissue are essential for the traveller in Asia. If you don’t have one by the time you are at a hawker center, buy one from the drink stand (there’s always one open), or borrow one from your friend who came along and was better prepared than you :-)

- Make sure to reserve a seat. One of the customs here is to “reserve” a seat at a table. Send your friends to buy their food first and then when they return it’s your turn. You did bring someone to eat with, didn’t you? Yes, it does waste valuable table space, seeing as many people in a hawker center are there just to reserve a space. But when in Rome…

- “Self-service” In the US, this means you pump your own petrol. But in Singapore, it means that you have to get the food after it’s cooked and return to your seat. If there’s no such sign, you can let the stall owner have their helper deliver it to your table (yes, that’s what the table number is for).

- “$2 $3 $5″: Don’t let someone fool you into thinking these are different prices for locals, expats and tourists. Nah, it’s for the portion size you might want to eat. Many dishes can be made with more ingredients to make a richer plate of food. You can tell the stall owner how much money you wish your food to cost. Typically, a higher price corresponds to more meat/veggies and not carbo, so it’s not quite the same as upsizing your McMeal.

- So are you ready? Listen to what locals tell their hawkers when ordering. If you can pick out the meaning, you’ll hear the dialogue being negotiated in a semi-fixed order. Usually, people tell the hawker what dish they want, followed by the dollar amount, whether they want chili or not, and specify *exactly* how they want it cooked (Burger King’s got nothing on this.) Other details follow: whether they want it “packet” (to go) or to “makan” (eat here, “makan” is eat/food in Malay) and where they are sitting (if it is to be delivered to your table).

-Min’s 2009 ACL-IJCNLP update. ‘Food Republic’ downstairs from the conference venue is *not* the same as a hawker center, no matter what it advertises.  That’s not to bash Food Republic, just that the atmosphere (and heat and humidity) are completely different.  Go out and explore.  The closest (food-wise) bearable hawker center to Suntec City would be Lau Pa Sat, Newton Circus or the Bugis (pronounced ‘BOO-gis’; try saying ‘BUG-is’ to a local is a sure way to get them to fall over laughing) hawker center.

Talk to any Singaporean or resident here and they will always be able to chat about their favorite hawker stands.  Beats talking about the weather for a conversation opener (”Man, it sure is hot and humid these days…”).  Wise up by checking out some of the hungrygowhere or makansutra websites (you do remember what ‘makan’ means, right?)

keropokman commented on this post in SIGIR ‘08, so I’ll just share it here too.  (Visit his site if you want to salivate about food):

The term Hawker Centre is an oxymoron.

A Hawker moves around :-)

If you realise, they have all been renamed “Food Centres” in almost all the ’so called hawker centres” :-)

The convenience of the hand phone

Singapore prides itself on a clean sweep of corruption and debris and clutter, but this can also manifest in other unintended side effects.  In Singapore — and probably most other countries now — it’s dreadfully hard to find a public pay phone.

Even when you do manage to find one (hint: big shopping malls in Suntec City or in large hotels), sometimes they are just phones that take electronic prepaid cards.  How do you then make the call to look up your friends in Singapore?

A good option is to bring your mobile phone with you.  Singapore runs standard GSM service through several mobile providers.  If you have a (dual, tri, quad-band) GSM phone it should work with Singapore’s providers as long as you get a new SIM card.  This would be my recommended option — to purchase a short-term prepaid, refillable SIM card.

Getting a prepaid SIM card in Singapore is generally quite easy, activation is instant, and calling rates are quite attractive.

The prepaid SIM cards in Singapore come in various denominations ranging from S$10 to S$50. There are 3 mobile phone service providers that offer prepaid phone service in Singapore – SingTel, MobileOne (M1) and Starhub.

Prepaid SIM cards in Singapore for any of the three phone companies can be purchased at the following locations:

• Retail outlets of Singtel, Starhub, and M1.  There are outlets for these stores in Suntec City.
7-eleven stores and Cheers Convenience Stores.  These are everywhere, including the Changi airport.  If you have to have your phone connection right away, this is it.
Singapore Post

Since 2006, the Singapore government has made prepaid SIM registration a mandatory requirement. This means the card must be registered under the name of the person who will be using it, in this case you. As a result, you will be required to produce your passport when you buy the prepaid mobile card (that means you should not forget to bring out your passport when you want go buy it). Once registered, the card is ready for use immediately.

Prepaid SIM Card balance in Singapore is normally valid for 6 months which means any unused balance will expire after 6 months, if not refilled (topped-up) by buying additional credit.  10 dollars may seem a lot of money but I personally find the peace of mind in having local rate calling at your convenience.  The prepaid cards all features slightly different long distance rates to your family and friends back home, but don’t vary too much.

So those linguists out there will wonder about the origins of the word ‘handphone’, more popularly used here than ‘mobile’ or ‘cell’.  Well that’s easy: ‘手机’ the Chinese translation is literally ‘hand machine’.  How’s that for pop etymology?

Durians: the “stuff” of Kings

Filed under: Conference Participants, Destination Singapore, Food Lovers, General Audience — Tags: , — Mahani Aljunied @ 1:51 pm
Durian

Durian

On a hot afternoon in Singapore like this one, a major preoccupation of mine is looking to find ways to cool down. Besides having the ceiling fan on, I do enjoy a platter of chilled, tropical fruits. I feel like papaya today. It’s not really in season, but you don’t really have to wait for a fruit to be in season anymore. Just pop by the nearest supermarket or fruit stand, and you’ll find a wide and attractive range of fruits from across the region. From Dragons (dragon fruit) to Dukus and of course, Durians.

The fruit synonymous to Singapore is the Durian. But, mind you, do not have a go at durians on any hot afternoon.  I fainted once while attempting this feat. It’s well-known in the area of holistic medicine as a rather ‘heaty’ fruit.

Esplanade Theatre Building

Esplanade Theatre a.k.a Durian building

Even if you’re new to Singapore, you might have heard about this rather controversial fruit.  The Durian is a native fruit of South-east Asia, and a favourite of many Singaporeans, Malaysians, and Thais alike. In fact, it’s even a favourite of our fellow South-east Asian native, the orang utan.

So where’s the controversy? Not unlike other exotic treats, one man’s meat is at times another man’s poison (or should I quote the Malay proverb, duri dalam daging – a thorn in the flesh).

The size of a soccer ball, this fruit has a distinctive appearance with its spiky, olive green husk. Inside, you’ll find five neat segmented compartments, each segment separated from the other with a thick lining that encapsulates a cream-coloured, custard-like pulp. This creamy flesh that covers each large seed is relished by some, described as truly delicious and even regal – hence the name the King of fruits – but can be foul to others.

Inside the Durian

Opened Durian

But it’s not the unusual appearance of the durian that makes it different from other fruits. You can smell its pungent odour, literally, a mile away. Some say, if you can get past the smell, you’ll most likely enjoy the durian’s taste. It doesn’t really taste the way it smells, but it’s strong enough to deter even the most adventurous of food experts like Andrew Zimmern. And if you think a whiff of air freshener would do the trick, think again. The smell of the durian is indeed resilient and could linger on for hours. So don’t wonder much if you see “No Durian” signs in public areas in Singapore.

Game for the Real Thing?

If you feel ‘brave’ enough and would like to have a taste of the fruit, then head straight for the real thing. There are many durian cafes on the island — a local haunt is a short stretch along Sims Avenue, between the Kallang and Aljunied MRT stations. A durian café is, for obvious reasons, an outdoor café serving durians that are selected by the customers and served directly in their husks. The tables and chairs are right next to the fruit stand.

And if you really like Durians, you might consider a Durian tour which takes you on a day trip (by road) to one of the durian orchards in Johor (southernmost Malaysian state).

Sweeter Alternatives

There are, should I say, safer ways to enjoy this fruit apart from eating it straight from its husk. Many of my friends not familiar with the fruit prefer this option. The sweet and creamy taste and texture of the durian makes it an ideal ingredient in desserts. One local favourite is the pengat durian (a sweet durian pudding flavoured with cane-sugar and fragrant pandanus leaves), bubur pulut durian (basically the pengat, with glutinous rice included), dodol (a toffee-like traditional Malay dessert), and chendol (a traditional Indonesian cold dessert). The durian even found its way to more contemporary cake recipes. Secret Recipe (there are 2 in the Marina area Suntec City Mall, Temasek Boulevard, 3 #B1-053/054 and Marina Square, Raffles Boulevard, 6 #03-211) has a mean Durian cake. Every supermarket will carry Durian-flavoured ice creams. Some bakeries (like Polar Café and Prima Deli) also feature durian meringues and even milkshakes! My personal favourite would be Bengawan Solo that features the more traditional desserts including those containing durian.

What’s in a Durian’s name?

Rambutan

Rambutan

The local name of this fruit dubbed as the King of Fruits — duri- plus the suffix -an — roughly means “thorny stuff” in Malay. It follows the naming convention of the durian’s smaller, less painful rival, “hairy stuff” (a.k.a the Rambutan).

Rambutans are often confused with their cousins the Pulasans, which are just as red outside and as juicy inside. The name Pulasan correctly indicates that one has to pulas (twisting with both hands while firmly gripping) the rind of the fruit, breaking it to get to its juicy, translucent edible part.

Pulasan

Pulasan

It’s been referred to as the Rambutan’s more ‘fashionable’ counterpart, particularly in the 80’s, I suppose due the popularity of it’s punk style, crew-cut skin.

Interacting with NLP

Filed under: Bleeding Edge, General Audience — Tags: , — Jesse P. Gozali @ 11:39 pm

As a modern society, we interact with many things in our lives: from household appliances and mobile devices to pencil sharpeners and door handles. We take these everyday things for granted and interact with them seamlessly, but the truth is, there was a thorough design process for each and every one of them. Don Norman talks about this very problem in his book, the Design of Everyday Things [1]. If everything was designed perfectly, everyone is happy. Sometimes however, the way we think an object should be used, differs from how the designers envisioned it. There is no sign on a door; should we pull the door or should we push it?

Since Norman’s book was first published in 1990, people’s notion of everyday things have grown to include more than just tangible objects. Every day, people interact with their operating systems, email clients, web browsers, search engines, web applications, games, etc. For these systems to function efficiently, users need to understand how to use them. Unfortunately, sometimes the same cognitive gap between user and designer becomes an obstacle. Consider searching for records in a digital library as an example. A 1998 survey indicated that a major usability problem with digital libraries is in finding the appropriate keywords for search [2]. In other words, users are having difficulty interacting with the search engine. Here and beyond digital libraries, the cognitive gap is often about translating user needs and/or tasks into keywords.

How can we close this cognitive gap? Perhaps we invite users to naturally express their needs and tasks in writing. Can we use NLP to understand them?

Powerset is a search engine whose goal is to “change the way people interact with technology by enabling computers to understand our language”. Since May 2008, Powerset provides users the ability to search and discover information in Wikipedia articles. Queries such as “When did earthquakes hit Tokyo” and “What are the ingredients in beer” are processed appropriately.

Jono DiCarlo presenting Ubiquity

Jono DiCarlo presenting Ubiquity

Ubiquity from Mozilla Labs is another example where interactions on the web are centralized on the user and their needs and tasks, rather than around individual web sites. With Ubiquity, you control your web browser with language instructions. You can ask it to send an email of some text with a map and address of some location with just one sentence and one click. Without ubiquity, laborious cutting and pasting of text and images between various websites is needed.

There is still plenty of work to be done. Other kind of users need to be addressed, other interaction problems to be solved. Our job is only finished when the interaction with our systems becomes so transparent that users don’t even realize that our interface work-of-art is actually there. A rather ironic situation, but hopefully still content — with ourselves and our work.

Singapore is 4th most liveable city in Asia [On The News]

Filed under: Conference Participants, General Audience, On The News — Tags: , , — Chris Henry @ 3:28 pm

Colourful Singapore

Just in today, Singapore is ranked 4th most liveable city in Asia (after Osaka, Tokyo, and Hong Kong). It also ranks first in South-east Asia. Worldwide, it’s ranked 54th. This result is from this year’s liveability survey done by the Economist Intelligence Unit (the short article from the Economist is here and the full survey can be bought for a whooping $250).

The survey takes into account 5 broad categories (with 30 different factors): stability, health care, culture and environment, education, and infrastructure. It then scores each city from 1 (intolerable) to 100 (ideal). Cities with rating above 80 should have few challenges to their living standards. Singapore scores 88.5.

Singapore: Best Sightseeing City in APAC [On The News]

Sorry for the slow posting, have been away in Copenhagen and Berlin for the past week and flying of to San Francisco in a few hours. Well, that means I have been to Changi Airport twice in the past week; in fact I’m here now for the third time, posting this from the coffee connoisseur (tcc) cafe at Terminal 3. I have collected some brochures and other stuffs from the airport and am planning a post about it. Well, that’s probably for tomorrow, when I’ve safely landed in SF.

Well, meanwhile, I’ve just gotten the news from a friend that Singapore was just selected as the best sightseeing city in Asia Pacific at Seoul Tourism Award [see here and here]. As a long-time resident of Singapore, I was quite surprised by the award. However, when I do think about all the tourist attractions (from shopping to food to nightlife), Singapore probably does deserve the award. Well, for you guys who are coming here in August, judge it for yourself! (And tell us! I’m very curious to know.)

The next bit is probably quite useful to you. In addition to the sightseeing award, it also won the best website for city tourism promotion award (yeah, long and mouthful). That’s good news of course. In this Internet era, I found it frustrating being unable to find good, well-organized website resource about a particular city (having just experienced this when I was about to visit Berlin last week), so do check out Uniquely Singapore site. [And again, judge it for yourself whether it deserves the award; this time, I do think it does (:.]

Lieutenant Commander Data (a.k.a. will NLP ever make Data realistic?)

Filed under: Conference Participants, General Audience, Miscellanoids — Tags: , , — Chris Henry @ 1:47 pm

Having watched the reboot of Star Trek recently (and spending this morning musing of what to post for the blog), I remembered one of my favourite characters from the Star Trek of my generation, a.k.a. Star Trek – The Next Generation (TNG): Lt. Cmd. Data. [I was born in 1986, too young to appreciate the original Star Trek. Sadly, my memory of TNG is not exactly very lucid either, but here goes an attempt.]

Lt. Cmd. Data

Lt. Cmd. Data

Well, Data is definitely the pinnacle, one of the end points that NLP can reach. An android that is able to communicate with humans in human language, rather than in programming languages, clicks of a mouse, or touch on the screen. Given the fact that he’s able 60 trillions operations a second (and over 80 petabytes of memory), that might not be too surprising. Well, no, actually, now that I think about it, it is pretty surprising. Assuming 3GHz processor, current computers can perform those 60 trillions operations in under 10 minutes. Given the fact that natural language processing and computational linguistics sometime utilize tens of machines (heck, Google utilizes clusters of probably hundreds of machines and megahuge corpus), those 60 trillions operations suddenly seems very small. Yet, we are still so far behind what is portrayed by Data. Or do we really?

Truth be told, yes, I do believe we’re behind Data. But if you had been faithfully following Star Trek, Data isn’t that good with NLP (actually I only realized this now). He has not mastered contractions (shortening of “I am” to “I’m”, “is not” to “isn’t”, etc.). His speech is also more monotonous and rigid (although in one of the episode, where we were shown a future Data who is a professor at Cambridge, Data is portrayed as having more nuanced speech). Data is also less capable to use inflections. Minus these points, on the other hand, Data represents a possibility for NLP that we have not yet attained. It is very exciting indeed. (:

Lastly, of course, I can’t write a Star Trek post without alluding to universal language translator engine that is supposed to instantaneously translate languages into understandable language (well, in this case, English; or whatever language Star Trek is being dubbed into). Can we ever make such devices? What do you think about it? (: [Talking about universal language translator, I think Star Wars' protocol droids (such as C-3PO), which can translate between many languages, are more likely to be created than this one.]
