LIRICS mid-term review2 Summary of the presentation WP3: 1st year objectives objectives and work done in T3.1, T3.2 status of deliverables in T3.1, T3.2 Main Achievements: SynAF NWI accepted and Working Draft discussed at ISO level Next Steps: Data Categories for Syntactic Annotation Synergies with other LIRICS WPs, ISO activities, meetings

LIRICS mid-term review3 Task 3.1: Survey Task 3.1: Evaluation of initiatives for morpho-syntactic and syntactic annotation. Objectives:Evaluate past and current initiatives dealing with standardisation, guidelines and recommendations for morpho-syntactic and syntactic annotation. Background for starting ISO standardization activity on syntactic annotation (model + data categories) Results: Deliverable 3.1 (V1 and V2).

LIRICS mid-term review5 Task 3.2: ISO Proposal for a standard for Syntactic Annotation Submit to ISO TC37/SC4 a New Work Item on Syntactic Annotation, and go through the ISO procedure till the final document. Objectives: Proposal for morpho-syntactic annotation meta-model standard together with a wide coverage of data category selection formorpho-syntatic annotation Results: New Work Item on Syntactic Annotation (SynAF) succesfully submitted to ISO TC37/SC4. Ongoing Discussion on the Working Draft

LIRICS mid-term review7 The SynAF Proposal Syntactic Annotation has 2 Functions in NLP 1) To represent linguistic constituencies, like Noun Phrases (NP), describing a structured sequence of morpho-syntactically annotated items, where we consider also constituents built from non-contiguous elements, and 2) To represent dependency relations dependency information can exist between morpho-syntactically annotated items within a phrase (an adjective is the modifier of the head noun within an NP) or describe a specific relation between syntactic constituents at the clausal and sentential level (i.e. an NP being the "subject" of the main verb of a clause or sentence). In the first case we speak of an internal dependency and in the second case we speak of an external dependency. But the dependency relation can also be stated including empty elements (like the pro-drop property in romance languages)

LIRICS mid-term review8 The SynAF Proposal (2) SynAF is concerned thus with a meta-model that covers both dimensions of syntactic constituency and dependency, and SynAF is proposing a multi-layered annotation framework that allows the combined and interrelated annotation of language data along both lines of consideration. Also the data- categories to be proposed to ISO standardization will be about the basic annotation concerning both dimensions.

LIRICS mid-term review9 The SynAF Proposal (3) A main starting point: Tiger The Tiger annotation framework foresees 2 types of annotation: for constituency (represented than by a node label in the annotation framework) and for dependency (represented as an edge label in the annotation framework).

LIRICS mid-term review10 The SynAF Proposal (4) Another starting point: ISST The approach followed in the ISST (Italian Syntax Semantic Treebank) framework, is similar to the one proposed in Tiger, in the sense that a multi-layered syntactic annotation strategy is proposed: One level for constituency and one level for dependency, with a pointing mechanism for referring from the second level to the first one.
