Step 2: Cultural image annotation– Keyword extraction– Semantic relation acquisition– Image annotation games

Step 3: Cultural knowledge service– Cultural knowledge platform for application service

CULTURAL IMAGE ANNOTATION


Keyword Extraction

• Some keywords are readily available in the set tags, but many of them are still missing.

• Our task is to extract those missing keywords from the description and title.


Keyword Extraction

• Some keywords can be linked to external pages, e.g. Wikipedia.

• Our task is to find appropriate articles corresponding to those keywords.


Method for KW Extraction

• Chunking model (Uchimoto et al., 2004) for keyword extraction


Training Data Preparation• Generate a keyword list from tags and titles that are not

shorter than 5 characters and not longer than 30 characters• Segment descriptions using a state-of-the-art Thai word

segmentation algorithm (Kruengkrai et al., 2009)• Note that the word segmentation algorithm was trained using

ORCHID corpus and TCL’s lexicon (contents of ORCHID corpus and our current data are quite different)

• Label the segmented descriptions with the keyword list


Training Data• Description

ผ้าซิน่ลายมดัหมีบ่า้นปทมุแก้ว …เป็นงานฝีมอืพื้นบา้น ..


Labeling

• Apply BIO tagging– B: beginning position of a keyword– I: intermediate (or end) position of a keyword – O: other words

• If several matches are possible, select the longest one (like in the previous example)


Training Data• Description

ผ้าซิน่ลายมดัหมีบ่า้นปทมุแก้ว …เป็นงานฝีมอืพื้นบา้น ..

• Segmented/Tagged/Labeled DescriptionWord POS tag

Chunking Model

Preliminary Experiment Result

• 3000 examples for training, 500 examples for testing

• Based on Margin Infused Relaxed Algorithm (MIRA), Crammer et al., 2005– Baseline features (Unigram and Bigram) +– 3 character prefix/suffix of current word +– 3 consecutive POS tags

• Recall=0.8256, Precision=0.9061, F1=0.8640


Semantic Relation Acquisition

• Extract commons syntactic patterns between two nouns

• Our task is to acquire triples (ei , rij , ej ), where– ei and ej are entities (keywords)

– rij is a relationship between them


• ExampleTitle: วดัทุ่งDescription: วดัทุ่ง มอีายุราว 500 ปี สนันิฐานวา่สรา้งขึน้ในสมยักรุงสโุขทัยTitle: วดัตราชูDescription: วดัตราชู สรา้งขึน้ในสมยั กรุงศรอียุธยาตอนต้น ราว พ.ศ.2076Title: หลวงพอ่ขาวDescription: เป็นพระพุทธรูปเก่าแก่เนื้อหนิทรายปางสมาธ ิขนาดหน้าตักกวา้ง ๒ ศอกประดิษฐานอยูใ่นวหิารวดัหลวงวดัสนันิฐานวา่สรา้งขึน้ในสมยัอยุธยาTitle: พระพุทธรูปปางมารวชิยัDescription: สรา้งขึน้ในสมยัรตันโกสนิทรต์อนต้นTitle: วหิารวดัโยธานิมติDescription: สรา้งขึน้ในสมยัพระบาทสมเด็จพระเจา้ตากสนิมหาราช

ESP Game and Peekaboomproposed by Luis von Ahn, May 25, 2006 by Pete Cashmore

• ESP Game – In the ESP Game, the two players are shown an image and asked to enter a word that describes it. The players can’t see each other’s guesses. The aim is to enter the same word as your partner in the shortest possible time. But there’s an ulterior motive here: much of the data is recorded, and could be used to power image search engines in the future. What’s cheaper – paying thousands of Mechanical Turkers to label all the images on the web, or tricking people into doing it for free?

• Peekaboom – Peekaboom takes the ESP Game to the next level. Unlike the ESP Game, it’s asymmetrical. To start, one user is shown an image and the other sees an empty black space. The first user is given a word relating to the image, and the aim is to communicate that word to the other player by revealing portions of the image. So if the word is “eye” and the image is a face, you reveal the eye to your partner. But the real aim here is to build a better image search engine: one that could identify individual items within an image.


ESP Game

• Two players are shown an image

• asked to enter a word that describes it.

• The aim is to enter the same word as your partner in the shortest possible time.

Peekaboom• One user is shown a

named image and show the part of the image according to the name

• Another user gives a word relating to the image

• The aim is to enter the same word as it is named in the shortest possible time.

Extended Peekaboom• One user is shown a named

image and show the part of the image according to the name

• Another user gives a word relating to the image

• The aim is to enter the same word as it is named in the shortest possible time.

• A word from the Synset can be matched.

• Once a synset is selected cross language matching can be determined.

Demo• ESP-like game

– http://m-culture.in.th/game/esp_game– Play mode

• Single player mode: play against history• Two-player mode: guess to match each other

• Extended Peekaboom game– http://m-culture.in.th/game/peekaboom– Play mode

• Single player mode: play against history• Two-player mode: guess to match each other

– For Thai language, use AWN to support synonym, hypernym, hyponym, meronym, and holonym

– For other languages, use AWN to support synonym only

http://m-culture.in.th/game/esp_game

http://m-culture.in.th/game/peekaboom


Preliminary Experiment

• 18 images played by 19 persons. For each image, we allow 60 seconds to guess a proper word.

• AWN can expand the matching in 67 cases or increase 22% of matching ratio.

Summary

• From this ESP-like game, we successfully named the images or at least obtained a list of candidates for labeling the object in the image to be used in the next extended Peekaboom game.

• Synonym, hypernym, hyponym, meronym, holonym from AWN can help expanding the matching ratio.

• Cross language image labeling is realized by AWN synonym.


Future Work

• Enhancing keyword extraction to find more term candidate for image matching

• Call for participation of the extended ESP and Peekaboom games for image labeling
