A probabilistic model for analysing species cooccurrence
نویسنده
چکیده
Aim To develop a new probabilistic model that can be used to test for statistically significant pair-wise patterns of species co-occurrence. The model gives the probability that two species would co-occur at a frequency less than (or greater than) the observed frequency if the two species were distributed independently of one another among a set of sites. The model can be used to classify species associations as negative, positive or random.

A Probabilistic Setting and Lexical Cooccurrence Model for Textual Entailment
This paper proposes a general probabilistic setting that formalizes a probabilistic notion of textual entailment. We further describe a particular preliminary model for lexical-level entailment, based on document cooccurrence probabilities, which follows the general setting. The model was evaluated on two application independent datasets, suggesting the relevance of such probabilistic approache...

متن کاملProbabilistic Coordination Disambiguation in a Fully-Lexicalized Japanese Parser
This paper describes a probabilistic model for coordination disambiguation integrated into syntactic and case structure analysis. Our model probabilistically assesses the parallelism of a candidate coordinate structure using syntactic/semantic similarities and cooccurrence statistics. We integrate these probabilities into the framework of fully-lexicalized parsing based on largescale case frame...
متن کاملSemi-parametric Quantile Regression for Analysing Continuous Longitudinal Responses
Recently, quantile regression (QR) models are often applied for longitudinal data analysis. When the distribution of responses seems to be skew and asymmetric due to outliers and heavy-tails, QR models may work suitably. In this paper, a semi-parametric quantile regression model is developed for analysing continuous longitudinal responses. The error term's distribution is assumed to be Asymmetr...
متن کاملProbabilistic Latent Semantic Analysis
Probabilistic Latent Semantic Analysis (pLSA) is a technique from the category of topic models. Its main goal is to model cooccurrence information under a probabilistic framework in order to discover the underlying semantic structure of the data. It was developed in 1999 by Th. Hofmann [7] and it was initially used for text-based applications (such as indexing, retrieval, clustering); however i...
