Title : Deep parsing and its applications (深い構文解析とその応用)

Abstract :
深い構文解析とは，自然言語文を入力とし，その深い言語構造（構文構造と意
味構造）を出力する構文解析技術である．文と意味構造との対応関係は複雑で
あり，単純なモデルでは計算が難しい．しかし，語彙化文法と呼ばれる枠組み
を用いることにより，高精度かつ高速な構文解析が可能となった．本トークで
は，深い構文解析のアプローチについて，浅い構文解析（係り受け解析など）
や semantic parsing と対比しながら，基本的なアイディア，本質的な違いな
どを概説する．また，深い構文解析の応用として，情報抽出や機械翻訳の研究
を簡単に紹介する．


Title: Deep parsing and its applications
Abstract:
Deep parsing is a natural language processing technology that computes deep linguistic structures, i.e., syntactic and semantic structures, from input text. In general, simple computational models do not work sufficiently for this task, because of the complexity of mappings between text and its semantics. However, linguistic theory called lexicalized grammar allows for accurate and efficient deep parsing. In
this talk, I describe fundamental ideas of deep parsing and essential differences from shallow parsing techniques such as dependency parsing. Additionally, I introduce applications of deep parsing, including information extraction and machine translation.

japanese talk with english slides, come on!

[PremierSullivan]

If you use the automated translation, its actually pretty easy to follow.  Yes, google's machine translation is not perfect, but with the subtitles it is possible to follow what is going on.

@jacekjacenty you don't know what he is saying so you don't know if what he says adds information to the slides. Furthermore, it is senseless to upload a video when a ppt file is better and enough.

[jacekjacenty]

@paucarre If you read a good book about computer parsing/translation of natural languages, then the slides will be self explanatory. I have watched only 7 minutes so far but I don't need to know Japanese to work out what he is trying to say.

[Monchanger]

@paucarre Silly American.  Just learn Japanese.

[paucarre]

@llothar68 I just want to know what he's saying. I'm sure that the guy isn't only reading the slides.... If Google uploads a this instead of a Power Point file means that the talk has additional information.

[llothar68]

@paucarre

You have Power Point subtitles? What else do you want?

[paucarre]

Japanese without subtitles? are you kidding?

LOL September 13, 1010 .... wow! great medival hack!!
