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. PNC 2012 Annual Conference and Joint Meetings, UC Berkeley, US., December 7-9, 2012
13
Keyword Extraction • Some keywords can be linked to external pages, e.g. Wikipedia. • Our task is to find appropriate articles corresponding to those keywords. PNC 2012 Annual Conference and Joint Meetings, UC Berkeley, US., December 7-9, 2012
14
Method for KW Extraction • Chunking model (Uchimoto et al., 2004) for keyword extraction PNC 2012 Annual Conference and Joint Meetings, UC Berkeley, US., December 7-9, 2012
15
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 PNC 2012 Annual Conference and Joint Meetings, UC Berkeley, US., December 7-9, 2012

Training Data • Description ผ้าซิ่นลายมัดหมี่บ้านปทุมแก้ว เป็นงานฝีมือพื้นบ้าน ….. PNC 2012 Annual Conference and Joint Meetings, UC Berkeley, US., December 7-9, 2012
17
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) PNC 2012 Annual Conference and Joint Meetings, UC Berkeley, US., December 7-9, 2012

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 PNC 2012 Annual Conference and Joint Meetings, UC Berkeley, US., December 7-9, 2012

Semantic Relation Acquisition • Extract commons syntactic patterns between two nouns • Our task is to acquire triples (e i, r ij, e j ), where – e i and e j are entities (keywords) – r ij is a relationship between them PNC 2012 Annual Conference and Joint Meetings, UC Berkeley, US., December 7-9, 2012

ESP Game and Peekaboom proposed 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.

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.
