Hinting Improbable Word-Link-Clouds for Cluster
Summary and Discovery
- Loui CS513 Proposal Fall 06
2
Problem
- There is too much to read
- We need skimming tools
- Text summarization is one way
- Improbable word and phrase extraction is another
- Word-Link-Clouds are also neat, e.g. Icosystems
text visualization

Building These Things
- Which words to extract?
- Which words get links?
- How big each word?
- How thick each link?
- How can you HINT words?
- How can you VARY views?
6
Hinting
- Keywords are a great hint
- Ontologies such as wordnet are helpful
- Synonyms, meronyms, hypernyms
- Domain-specific dictionaries are helpful
- IBK the interest-background corpus
7
- Nouns
- hypernyms Y is a hypernym of X if every X is a
(kind of) Y - hyponyms Y is a hyponym of X if every Y is a
(kind of) X - coordinate terms Y is a coordinate term of X if
X and Y share a hypernym - holonym Y is a holonym of X if X is a part of Y
- meronym Y is a meronym of X if Y is a part of X
- Verbs
- hypernym the verb Y is a hypernym of the verb X
if the activity X is a (kind of) Y (travel to
movement) - troponym the verb Y is a troponym of the verb X
if the activity Y is doing X in some manner (lisp
to talk) - entailment the verb Y is entailed by X if by
doing X you must be doing Y (snoring by sleeping)
- coordinate terms those verbs sharing a common
hypernym - Adjectives
- related nouns
- participle of verb
- Adverbs
- root adjectives

IBK
- IBK is a set of documents
- That are interesting
- Presumably contain keywords or their relatives
- Lack of representation Lack of interest
- Contains implicit information about granularity
- Lots of fine sports keywords IMPLIES detailed
interest - Variation/Repetition in IBK is as important as
inclusion
9
Varying
- Icosystems/MIT/Bonabeau GA/GP feedback
- Levine/WUSTL my view, your view
- Loui/WUSTL Reordering a cluster creates a new
view - 513/WUSTL any new ideas?
10
Proposal
- Working just with BBC news data
- Write
- Visualization software (fairly trivial)
- Ordered clustering engine (many directions
possible) - IBK extraction/matching engine
- Multiple views
11
Needed
- People I can supervise who will do my bidding
- Scripting programmers OR very good UNIX people
- People who I can communicate with who can get
things done quickly (not necessarily thoroughly)
