**Keynote [#m6aff977]
-Magnetoencephalography (MEG)
--word recognition
---visual cortices, Occipital Lobe --> abstract sign recognition
---lemma/lexical access
---recomposition of stem and suffix
**Keynote2: Prof. Wen-Lian Hsu (Academia Sinica) [#f848ead7]
-The archaelogist is in trouble ([people: [be]: [in a situation])
-The old archaelogist named John Doe is in a very serious trouble with his academia reputation.
--phrases --> classes (NP, PP, AdjP)
--Simple phrase: word, word combination
--Complex phrase: named entity frame
--Scenerio frame:
--Frame elements
---exaple??
--How to score an Insertion?
--Principle Pattern Analysis
---60 patterns out of all the sentence structures will cover approximately 98%.
---Using that framework, you can do the insertion/deletion operations over the pattern.

-Language acquisition --> skimming huge amount of data --> wrong?
-Semantic trigger (Pinker) --> certain contexts
--text <--> knowledge (bootstrapping)
-Innate ability (Chomsky)
--grammar (linear sequence --> structure --> meaning)
-rationalism vs. empiricism
--Ken Church (2011): A pendulum swung too far toward empiricism/data
--Integrating [grammar, rule] into [data]
-Knowledge mining
--Triggering: Big knowledge to enhance NLP abilities
---entity linking
---relation extraction
-Entity linking
--MS --> Microsoft or Multiple sclerosis
--entity relation in knowledge domain (human knows all these relations)
--categories in knowledge
-How to use those structural knowledge to disambiguate the meaning of words in a certain context
-Build classifiers, looking at the context and tell which a certain word belongs to a particular entity
-Inference relationship among different cues with different strength.
-Semantic parsing
--Identify grammatical relationships
--Extract entity relationships
-Parsing: Current state of the arts
--F-value too high
--Most relations are very simple (DET-N, ADJ-N) and trivial
--Non-trivial one: PP attachment
---accuracy is around 80-85%
-semantically crucial problems are not properly solved by current parsing techniques
-They use HPSG
-Fragments of parsing are compared to each other and compared in terms of similarities.
-inferences involved --> difficult
-statistical models of inferences have become scalable and feasible.
-integration of NLP with knowledge-based inferences is becoming a practical framework of natural language understanding.
