TL;DR: The authors investigate the syntax of extraposition in the HPSG framework and provide an analysis using a nonlocal dependency and lexical rules, and predict constraints on multiple extraposition with fronting and coordination.
Abstract: This paper investigages the syntax of extraposition in the HPSG framework. We present English and German data (partly taken from corpora), and provide an analysis using a nonlocal dependency and lexical rules. The condition for binding the dependency is formulated relative to the antecedent of the extraposed phrase, which entails that no fixed site for extraposition exists. Our account allows to explains the interaction of extraposition with fronting and coordination, and predicts constraints on multiple extraposition.

TL;DR: This paper presents a constraint-based multi-agent strategy to coreference resolution of general noun phrases in unrestricted English text and finds that the most recent antecedent always contains little information to directly determine the coreference relationship with the anaphor.
Abstract: This paper presents a constraint-based multi-agent strategy to coreference resolution of general noun phrases in unrestricted English text. For a given anaphor and all the preceding referring expressions as the antecedent candidates, a common constraint agent is first presented to filter out invalid antecedent candidates using various kinds of general knowledge. Then, according to the type of the anaphor, a special constraint agent is proposed to filter out more invalid antecedent candidates using constraints which are derived from various kinds of special knowledge. Finally, a simple preference agent is used to choose an antecedent for the anaphor form the remaining antecedent candidates, based on the proximity principle. One interesting observation is that the most recent antecedent of an anaphor in the coreferential chain is sometimes indirectly linked to the anaphor via some other antecedents in the chain. In this case, we find that the most recent antecedent always contains little information to directly determine the coreference relationship with the anaphor. Therefore, for a given anaphor, the corresponding special constraint agent can always safely filter out these less informative antecedent candidates. In this way, rather than finding the most recent antecedent for an anaphor, our system tries to find the most direct and informative antecedent. Evaluation shows that our system achieves Precision / Recall / F-measures of 84.7% / 65.8% / 73.9 and 82.8% / 55.7% / 66.5 on MUC-6 and MUC-7 English coreference tasks respectively. This means that our system achieves significantly better precision rates by about 8 percent over the best-reported systems while keeping recall rates.

TL;DR: As expected, negative maternal perception at 1-month old was associated with subsequent insecure adult attachment status, and the study hypothesis was supported.
Abstract: The goal of the present study was to examine the predictive relation between an individual's newborn status, as rated with the Neonatal Perception Inventories (NPI), and his or her adult attachment...

TL;DR: Ahn et al. as discussed by the authors show that the distribution of exceptionally behaving reflexive anaphors is structurally constrained, which implicates that there must a be syntactic account for these prosodic properties.
Abstract: Author(s): Ahn, Byron Thomas | Advisor(s): Jun, Sun-Ah; Sportiche, Dominique | Abstract: Across languages, there is variability in the surface realization of reflexivity, according to various sets of properties. For example, there are languages (e.g. Greek, Lakhota) that seem to treat some of their reflexive clauses as being in a non-active voice, similar to a passive. There are also languages (e.g. French, Kannada) in which reflexivity is encoded differently depending on whether the antecedent is the subject or not. In this way, English seems to be different: reflexivity is apparently realized in a homogeneous way - filling an argument position with an anaphoric expression like themselves - regardless of clausal voice or grammatical role of the antecedent.This homogeneity is an illusion. Despite using a single set of anaphoric expressions for reflexivity in various situations, reflexive anaphors in English fall into two classes: those that exhibit exceptional prosodic behaviors, and those that do not.This exceptionality can be directly observed in two domains: the distribution of "default" phrasal stress, and the distribution of a certain focal accent. From the results of expirments on speech production and perception, I show that the distribution of exceptionally behaving reflexive anaphors is structurally constrained. This implicates that there must a be syntactic account for these prosodic properties.Assuming that syntactic structure plays a near deterministic role in prosody (an assumption going back to even the earliest generative work on phrasal stress; Chomsky and Halle 1968:25), I argue for a more refined syntactic structure of reflexivity. Briefly, I demonstrate a sub-class of reflexive anaphors in English undergo a syntactic movement (to a reflexive VoiceP). This movement, along with independently motivated mechanisms for placement of phrasal stress and focal accents, derives the heterogeneous prosodic behaviors of reflexives in English. Crucially, this analysis does not require the prosodic component to have any stipulations for specific (classes of) words, in line with a Minimalist approach to the Syntax-Prosody Interface.This model of reflexivity simultaneously reduces the amount of theoretical machinery necessary to achieve descriptive adequacy, while also enhancing the model's predictive power. Moreover, this research has broad theoretical implications, beyond just reflexives in English. This theory is able to unify the various morpho-syntactic instantiations of reflexivizing functions - across languages - as being related to the Reflexive VoiceP. It also establishes a core set of properties that define clausal reflexivity, each of which are the result of the formal properties of the reflexive Voice0. Finally, it provides direct support for the hypothesis that syntactic and prosodic structures are maximally isomorphic, with prosodic cues in the signal giving direct evidence for otherwise invisible syntactic structure.

TL;DR: This paper presents machine learning approach for the classification of Demonstrative Pronouns for Indirect Anaphora in Hindi corpus and suggests looking for certain patterns following the indirect anaphor and marking demonstrative pronoun as directly or indirectly anaphoric accordingly.
Abstract: In this paper, we present machine learning approach for the classification indirect anaphora in Hindi corpus. The direct anaphora is able to find the noun phrase antecedent within a sentence or across few sentences. On the other hand indirect anaphora does not have explicit referent in the discourse. We suggest looking for certain patterns following the indirect anaphor and marking demonstrative pronoun as directly or indirectly anaphoric accordingly. Our focus of study is pronouns without noun phrase antecedent. We analyzed 177 news items having 1334 sentences, 780 demonstrative pronouns of which 97 (12.44 %) were indirectly anaphoric. The experiment with machine learning approaches for the classification of these pronouns based on the semantic cue provided by the collocation patterns following the pronoun is also carried out.
