Tracing armed conflicts with diachronic word embedding models
| Title | Tracing armed conflicts with diachronic word embedding models |
| Authors | Andrey Kutuzov, Erik Velldal, Lilja {\O}vrelid |
| Abstract | Recent studies have shown that word embedding models can be used to trace time-related (diachronic) semantic shifts in particular words. In this paper, we evaluate some of these approaches on the new task of predicting the dynamics of global armed conflicts on a year-to-year basis, using a dataset from the conflict research field as the gold standard and the Gigaword news corpus as the training data. The results show that much work still remains in extracting {}cultural{'} semantic shifts from diachronic word embedding models. At the same time, we present a new task complete with an evaluation set and introduce the {}anchor words{'} method which outperforms previous approaches on this set. |

Excess Risk Bounds for the Bayes Risk using Variational Inference in Latent Gaussian Models
| Title | Excess Risk Bounds for the Bayes Risk using Variational Inference in Latent Gaussian Models |
| Authors | Rishit Sheth, Roni Khardon |
| Abstract | Bayesian models are established as one of the main successful paradigms for complex problems in machine learning. To handle intractable inference, research in this area has developed new approximation methods that are fast and effective. However, theoretical analysis of the performance of such approximations is not well developed. The paper furthers such analysis by providing bounds on the excess risk of variational inference algorithms and related regularized loss minimization algorithms for a large class of latent variable models with Gaussian latent variables. We strengthen previous results for variational algorithms by showing they are competitive with any point-estimate predictor. Unlike previous work, we also provide bounds on the risk of the \emph{Bayesian} predictor and not just the risk of the Gibbs predictor for the same approximate posterior. The bounds are applied in complex models including sparse Gaussian processes and correlated topic models. Theoretical results are complemented by identifying novel approximations to the Bayesian objective that attempt to minimize the risk directly. An empirical evaluation compares the variational and new algorithms shedding further light on their performance. |

Integrating Decompositional Event Structures into Storylines
| Title | Integrating Decompositional Event Structures into Storylines |
| Authors | William Croft, Pavl{'\i}na Pe{\v{s}}kov{'a}, Michael Regan |
| Abstract | Storyline research links together events in stories and specifies shared participants in those stories. In these analyses, an atomic event is assumed to be a single clause headed by a single verb. However, many analyses of verbal semantics assume a decompositional analysis of events expressed in single clauses. We present a formalization of a decompositional analysis of events in which each participant in a clausal event has their own temporally extended subevent, and the subevents are related through causal and other interactions. This decomposition allows us to represent storylines as an evolving set of interactions between participants over time. |

Statistical Models for Unsupervised, Semi-Supervised Supervised Transliteration Mining
| Title | Statistical Models for Unsupervised, Semi-Supervised Supervised Transliteration Mining |
| Authors | Hassan Sajjad, Helmut Schmid, Alex Fraser, er, Hinrich Sch{"u}tze |
| Abstract | We present a generative model that efficiently mines transliteration pairs in a consistent fashion in three different settings: unsupervised, semi-supervised, and supervised transliteration mining. The model interpolates two sub-models, one for the generation of transliteration pairs and one for the generation of non-transliteration pairs (i.e., noise). The model is trained on noisy unlabeled data using the EM algorithm. During training the transliteration sub-model learns to generate transliteration pairs and the fixed non-transliteration model generates the noise pairs. After training, the unlabeled data is disambiguated based on the posterior probabilities of the two sub-models. We evaluate our transliteration mining system on data from a transliteration mining shared task and on parallel corpora. For three out of four language pairs, our system outperforms all semi-supervised and supervised systems that participated in the NEWS 2010 shared task. On word pairs extracted from parallel corpora with fewer than 2{%} transliteration pairs, our system achieves up to 86.7{%} F-measure with 77.9{%} precision and 97.8{%} recall. |

Effective Online Reordering with Arc-Eager Transitions
| Title | Effective Online Reordering with Arc-Eager Transitions |
| Authors | Ryosuke Kohita, Hiroshi Noji, Yuji Matsumoto |
| Abstract | We present a new transition system with word reordering for unrestricted non-projective dependency parsing. Our system is based on decomposed arc-eager rather than arc-standard, which allows more flexible ambiguity resolution between a local projective and non-local crossing attachment. In our experiment on Universal Dependencies 2.0, we find our parser outperforms the ordinary swap-based parser particularly on languages with a large amount of non-projectivity. |

Chunk-based Decoder for Neural Machine Translation
| Title | Chunk-based Decoder for Neural Machine Translation |
| Authors | Shonosuke Ishiwatari, Jingtao Yao, Shujie Liu, Mu Li, Ming Zhou, Naoki Yoshinaga, Masaru Kitsuregawa, Weijia Jia |
| Abstract | Chunks (or phrases) once played a pivotal role in machine translation. By using a chunk rather than a word as the basic translation unit, local (intra-chunk) and global (inter-chunk) word orders and dependencies can be easily modeled. The chunk structure, despite its importance, has not been considered in the decoders used for neural machine translation (NMT). In this paper, we propose chunk-based decoders for (NMT), each of which consists of a chunk-level decoder and a word-level decoder. The chunk-level decoder models global dependencies while the word-level decoder decides the local word order in a chunk. To output a target sentence, the chunk-level decoder generates a chunk representation containing global information, which the word-level decoder then uses as a basis to predict the words inside the chunk. Experimental results show that our proposed decoders can significantly improve translation performance in a WAT {`}16 English-to-Japanese translation task. | |

Personality Driven Differences in Paraphrase Preference
| Title | Personality Driven Differences in Paraphrase Preference |
| Authors | Daniel Preo{\c{t}}iuc-Pietro, Jordan Carpenter, Lyle Ungar |
| Abstract | Personality plays a decisive role in how people behave in different scenarios, including online social media. Researchers have used such data to study how personality can be predicted from language use. In this paper, we study phrase choice as a particular stylistic linguistic difference, as opposed to the mostly topical differences identified previously. Building on previous work on demographic preferences, we quantify differences in paraphrase choice from a massive Facebook data set with posts from over 115,000 users. We quantify the predictive power of phrase choice in user profiling and use phrase choice to study psycholinguistic hypotheses. This work is relevant to future applications that aim to personalize text generation to specific personality types. |

GraphDocExplore: A Framework for the Experimental Comparison of Graph-based Document Exploration Techniques
| Title | GraphDocExplore: A Framework for the Experimental Comparison of Graph-based Document Exploration Techniques |
| Authors | Tobias Falke, Iryna Gurevych |
| Abstract | Graphs have long been proposed as a tool to browse and navigate in a collection of documents in order to support exploratory search. Many techniques to automatically extract different types of graphs, showing for example entities or concepts and different relationships between them, have been suggested. While experimental evidence that they are indeed helpful exists for some of them, it is largely unknown which type of graph is most helpful for a specific exploratory task. However, carrying out experimental comparisons with human subjects is challenging and time-consuming. Towards this end, we present the \textit{GraphDocExplore} framework. It provides an intuitive web interface for graph-based document exploration that is optimized for experimental user studies. Through a generic graph interface, different methods to extract graphs from text can be plugged into the system. Hence, they can be compared at minimal implementation effort in an environment that ensures controlled comparisons. The system is publicly available under an open-source license. |
