This paper presents an algorithm for identifying noun-phrase antecedents of pronouns and adjectival anaphors in Spanish dialogues. We believe that anaphora resolution requires numerous sources of information in order to find the correct antecedent of the anaphor. These sources can be of different kinds, e.g., linguistic information, discourse/dialogue structure information, or topic information. For this reason, our algorithm uses various different kinds of information (hybrid information). The… 

Paninian grammar based hindi dialogue anaphora resolution

A Paninian grammar based heuristic model is presented to resolve entity-pronoun references in Hindi dialogue and it is shown that named entity, discourse information like subtopic boundary and animacy features increase the overall resolution accuracy.

Translation of Pronominal Anaphora between English and Spanish: Discrepancies and Evaluation

The MT interlingua approach named AGIR (Anaphora Generation with an Interlingua Representation) improves upon other proposals presented to date because it is able to translate intersentential anaphors, detect co-reference chains, and translate Spanish zero pronouns into English—issues hardly considered by other systems.

Solving Definite Descriptions through Dialogue Structure in Spanish

In this paper we present an study about the relationship between the definite description resolution and the structure of dialogues defining an anaphoric accessibility space. This relationship allows

AQA: a multilingual Anaphora annotation scheme for Question Answering

AQA, a multilingual anaphora annotation scheme that can be applied in Machine Learning for the improvement of Question Answering systems, has been used to annotate the collection of CLEF 2008 in Spanish, Italian and English.

Towards Multiple Antecedent Coreference Resolution in Specialized Discourse

This work presents the first version of an operational rule-based MAC resolution strategy for patent material that covers the three major types of MAC: (i) nominal MAC, (ii) MAC with personal / relative pronouns, and MAC with reflexive / reciprocal pronouns.

Using a Generative Lexicon Resource to Compute Bridging Anaphora in Italian

The results obtained seem to support the use of a Generative Lexicon based lexical resource with respect to WordNet-like ones due to the wider range of bridging anaphors which can be resolved.


It was observed that as the talk situations vary, types, frequencies, distances, retrieval qualities and thematic structure (patterning) of anaphors undergo dramatic changes too.

Knowledge{based Reference Resolution for Dialogue Management in a Home Domain Environment

A knowledge{based strategy for reference resolution implemented over an agent architecture which dierentiates the Knowledge and Action Managers from the Dialogue Manager has been applied to a home environment domain to solve successfully dierent phenomena such as quantication, anaphoric expressions and coordination.

A proposal of algorithm for solving definite descriptions through dialogue structure

This paper has been supported by the Spanish Government (MCYT) under grant TIC2000-0664-C02-01/02.



Dialogue Acts, Synchronizing Units, and Anaphora Resolution

The main finding of the corpus analysis is that less than half the pronouns and demonstratives have NP antecedents in the preceding text; 22% have sentential antecesents and the remainder have no identifiable linguistic antecedent.

An Algorithm for Pronominal Anaphora Resolution

The algorithm applies to the syntactic representations generated by McCord's Slot Grammar parser and relies on salience measures derived from syntactic structure and a simple dynamic model of attentional state and to models of anaphora resolution that invoke a variety of informational factors in ranking antecedent candidates.

Robust Pronoun Resolution with Limited Knowledge

This paper presents a robust, knowledge-poor approach to resolving pronouns in technical manuals, which operates on texts pre-processed by a part-of-speech tagger, and can be successfully adapted for other languages with minimum modifications.

Anaphora Resolution: A Multi-Strategy Approach

This paper examines the hypothesis that instead of attempting to construct a monolithic method for resolving anaphora, the combination of multiple strategies, each exploiting a different knowledge source, proves more effective - theoretically and computationally.

CogNIAC: high precision coreference with limited knowledge and linguistic resources

It is suggested that the system is resolving a sub-set of anaphors that do not require general world knowledge or sophisticated linguistic processing for successful resolution, and is very likely that they are largely domain independent and that they reflect processing strategies used by humans for general language comprehension.

An Architecture for Anaphora Resolution

The pronominal anaphora resolution module of Lucy, a portable English understanding system, is described, which has implemented a blackboard-like architecture in which individual partial theories can be encoded as separate modules that can interact to propose candidate antecedents and to evaluate each other's proposals.

Functional Centering - Grounding Referential Coherence in Information Structure

A revision of the principles guiding the ordering of discourse entities in the forward-looking center list within the centering model is proposed, claiming that grammatical role criteria should be replaced by criteria that reflect the functional information structure of the utterances.

Focusing and Description in Natural Language Dialogues

The relationship between focusing and definite descriptions in dialogue and its implications for natural language processing systems is examined and future research problems entailed in modeling the focusing process more generally are indicated.

Using grammatical inference methos for automatic part-of-speech tagging

This paper presents a part-of-speech tagging system based on a structural language model learnt automatically using grammatical inference techniques, in particular the ECGI algorithm, and evaluates the quality of the language model and the tagging accuracy.

The Representation and Use of Focus in a System for Understanding Dialogs

A representation of focus for language understanding systems, emphasizing its use in understanding task-oriented dialogs, and the use of the focus representation to make retrieval of items from the knowledge base more efficient.
