In these cases, the joint model, entertaining all ... factors of the joint model and train them separately. For mor- phological disambiguation, we use the baseline tag- ger described in §4.1. For dependency parsing, our baseline...

... models can use the same amount of training data, without giving unfair advantage to the joint model. Such set-up is also used for other re-ranking models (Collins, 2000). For training the joint ... English indicating present tense third person singular verb and A–FS-N for Bulgarian indicating a feminine singular adjective in indefinite form. In this work we predict only main P...

... graphical model representa- tion of the structured model linear models. In this paper we propose a structured model that overcomes limitations of the previous ap- proaches. For the model, we introduce ... argument role labeling. We use Semantic Labeled F1 for evaluation. For generating N-bests, we used the beam- search algorithm, and the number of N-bests was set to N = 6...

It is also able to utilize labelled information if available, obtaining improved performance. We ... present a novel model of transliteration min- ing defined as a mixture of a transliteration model and a non-transliteration model. The transliteration model is a joint sou...

In contrast, our study focuses on proposing a model for conducting expert search in a fine- grain scope of evidence (local context). 3 Fine-grained Expert Search Our research is to investigate ... and thus different impacts for expert locating. In contrast, this paper is concerned with propos- ing a probabilistic model for fine-grained expert search. In fine-...
