Intended learning outcomes

In order to pass the course, a student must be able to:

describe systems that perform the following tasks, apply them to authentic linguistic data, and evaluate the results:

Assignments and Examination

Grade G will be given to students who pass each assignment. Grade VG to those who pass the essay assignment and at least one of the other ones with distinction.

Compulsory Readings

Additional material will be used, in particular for the essay assignment.

Semantic role labeling/predicate argument structure analysis

List of SRL/PAS systems:
  1. SENNA

    SENNA (NEC machine learning department) is a software distributed under a non-commercial license, which outputs a host of Natural Language Processing (NLP) predictions: part-of-speech (POS) tags, chunking (CHK), name entity recognition (NER), semantic role labeling (SRL) and syntactic parsing (PSG). Focus on the semantic role labeling (SRL)component. Web page: http://ml.nec-labs.com/senna/

  2. The GATE Predicate-Argument EXtractor Component (PAX)

    As the Predicate-Argument EXtractor (The Semantic Software Lab, Canada) comes in form of a GATE component, you will obviously need GATE itself. Most of the required pre-processing components are included in the GATE distribution. Web page: http://www.semanticsoftware.info/pax

  3. Enju.

    Enju (University of Tokyo)also gives a predicate argument structure analysis as output. Enju is installed at the University's Linux network. There is also an online demo but is temporarily unavailable. So if you wish to test this system, use the version installed at University. The argument labels are described here.

  4. Illinois Semantic Role Labeler (SRL) Demo.

    Semantic Role Labeler (University of Illinois at Urbana-Champaign) is a machine-learning based tool that identifies shallow semantic information in a given sentence. The tool labels verb-argument structure following the notation defined by the Propbank project, identifying who did what to whom by assigning roles that indicate the agent, patient, and theme of each verb to constituents of the sentence representing entities related by the verb. This system applies machine learning techniques to learn to analyze a sentence. using Propbank section 02-21 as the training data, as used in the CoNLL-2005 shared task. Web page: http://cogcomp.cs.illinois.edu/page/software_view/SRL

  5. SwiRL: The Semantic Role Labeler

    SwiRL (by Mihai Surdeanu, University of Arizona) is a Semantic Role Labeling (SRL) system for English constructed on top of full syntactic analysis of text. The syntactic analysis is performed using Eugene Charniak's parser (included in this package). SwiRL trains one classifier for each argument label using a rich set of syntactic and semantic features. The classifiers are learned using one-vs-all AdaBoost classifiers.Web page: http://www.surdeanu.info/mihai/swirl/
