Statistical Learning of Natural Language Structured Input and Output

URL: http://disi.unitn.it/JNLE-SIO.html

Machine learning and statistical approaches have become indispensable for large part of

Computational Linguistics and Natural Language Processing research. On one hand,

they have enhanced systems' accuracy and have significantly sped-up some design phases,

e.g. the inference phase. On the other hand, their use requires careful parameter tuning and,

above all, engineering of machine-based representations of natural language phenomena,

e.g. by means of features, which sometimes detach from the common sense interpretation of

such phenomena.

These difficulties become more marked when the input/output data have a structured and

relational form: the designer has both to engineer features for representing the system input,

e.g. the syntactic parse tree of a sentence, and devise methods for generating the output,

e.g. by building a set of classifiers, which provide boundaries and type (argument, function or

concept type) of some of the parse-tree constituents.

Research in empirical Natural Language Processing has been tackling these complexities

since the early work in the field, e.g. part-of-speech tagging is a problem in which the input

--word sequences-- and output --POS-tag sequences-- are structured. However, the models

initially designed were mainly based on local information. The use of such ad hoc solutions

was mainly due to the lack of statistical and machine learning theory suggesting how models

should be designed and trained for capturing dependencies among the items in the

input/output structured data. In contrast, recent work in machine learning has provided several

paradigms to globally represent and process such data: structural kernel methods, linear

models for structure learning, graphical models, constrained conditional models, and

re-ranking, among others.

However, none of the above approaches has been shown to be superior in general to the

rest. A general expressivity-efficiency trade off is observed, making the best option usually

task-dependant. Overall, the special issue is devoted to study engineering techniques for

effectively using natural language structures in the input and in the output of typical

computational linguistics applications. Therefore, the study on generalization of new or

traditional methods, which allow for fast design in different or novel NLP tasks is one important

aim of this special issue.

Finally, the special issue is also seeking for (partial) answers to the following questions:

* Is there any evidence (empirical or theoretical) that can establish the superiority of one

class of learning algorithms/paradigms over the others when applied to some concrete natural

language structures?

* When we use different classes of methods, e.g. SVMs vs CRFs, or different paradigms,

what do we loose and what do we gain from a practical viewpoint (implementation, efficiency

and accuracy)? This question is particularly interesting, when considering different structure

types: syntactic or semantic both shallow or deep.

* Can we empirically demonstrate that theoretically motivated algorithms, e.g. SVM-struct,

improve simpler models, e.g. re-ranking, in the NLP case?

* Are there any other novel engineering approaches to NLP input and output structures?

TOPICS

For this special issue we invite submissions of papers describing novel and challenging work/results

in theories, models, applications or empirical studies on statistical learning for natural language

processing involving structured input and/or structured output. Therefore, the invited submission

must concern with (a) any kind of natural language problems; and (b) natural language structured

data.

Assuming the target above, the range of topics to be covered will include, but will not be limited to

the following:

* Practical and theoretical new learning approaches and architectures

* Experimental evaluation/comparison of different approaches

* Kernel Methods

* Algorithms for structure output (batch and on?line):

? structured SVMs, Perceptron, etc.

? on sequences, trees, graphs, etc.

* Bayesian Learning, Generative Models, Graphical Models

* Relational Learning

* Constraint Conditional models

* Integer Linear Programming approaches

* Graph-based algorithms

* Ranking and Reranking

* Scalability and effciency of ML methods

* Robust approaches

? noisy data, domain adaptation, small training sets, etc.

* Unsupervised and semi-supervised models

* Encoding of syntactic/semantic structures

* Structured data encoding deep semantic information and relations

* Relation between the syntactic and semantic layers in structured data
