==Deep vs Shallow Linguistic Processing==

Traditionally, deep linguistic processing has been concerned with computational grammar development (for use in both [[parsing]] and generation). These grammar were manually developed, maintained and were computationally expensive to run. In recent years, machine learning approaches (also known as [[shallow linguistic processing]]) have fundamentally altered the field of [[natural language processing]]. The rapid creation of robust and wide-coverage machine learning NLP tools requires substantially lesser amount of manual labor. Thus deep linguistic processing methods have received less attention. However it is the belief of some computational linguists that in order for computers to understand natural language or [[inference]], detailed syntactic and semantic representation is necessary.

Moreover, shallow methods doesmay lack human language 'understanding';. While humans can easily understand a sentence and it's meaning, shallow linguistic processing might lack human language 'understanding'. For example<ref>U.

:a) ''Things would be different if Microsoft was located in Georgia.'' <br>

<br>

In sentence A, a shallow [[information extraction]] system might infer wronlgy that Microsoft's headquarters was located in Georgia. While as humans, we understand from the sentence that Mircosoft office was never in Georgia.<br>

:b) ''The National Institue for Psychology in Israel was established in May 1971 as the Israel Center for Psychobiology by Prof. Joel.''

In sentence B, a shallow system could wrongly infer that Israel was establish in May 1971. Instead, humanly we know that it is the National Institute for Psychobiology that was establish in 1971.
