Ontologies have a special role in the UBIPOL system, they help to structure the policy related context, provide conceptualization for policy domain and use in the opinion mining process. In this work we presented a system called Ontology Based Opinion Mining Engine (OBOME) for analyzing a domain-specific opinion corpus by first assisting the user with the creation of a domain ontology from the ...

This paper is concerned with the lexical knowledge retrieval system created at the Linguistic Modelling Laboratory. The main goal of the system is to provide a powerful and comfortable interface for lexical knowledge retrieval from large morphological dictionary. To achieve this a constraint based approach is applied that leads to a very eeective algorithm. The algorithm for query building, whi...

Uncertainty-experienced by patients or communicated by physician and patient-may be crucial throughout the second opinion process. OBJECTIVE This study sought to investigate (1) how uncertainty influences men with prostate cancer to s...

The contribution of second opinion (SO) to improve diagnostic accuracy has been suggested for sarcoma but has never been established in population-based studies. METHODS Histological data of patients dia...

Opinion target extraction is one of the core tasks in sentiment analysis on text data. In recent years, dependency parser–based approaches have been commonly studied for opinion extraction. However, parsers are limited by language and grammatical constraints. Therefore, this work, a sequential pattern-based rule mining model, which does not such constraints, proposed cross-domain from product r...

This paper discusses how grammatical aspects of direct and indirect speech affect the evaluation argument from expert opinion. Direct is often characterized by having two different discourse acts and, consequently, deictic centres; regarded as one act with centre. These structures have pragmatic effects, mainly because in speech, reported content assumed to be faithful form content. In contrast...

Opinion mining in Arabic is a challenging task given the rich morphology of the language. The task becomes more challenging when it is applied to Twitter data, which contains additional sources of noise, such as the use of unstandardized dialectal variations, the nonconformation to grammatical rules, the use of Arabizi and code-switching, and the use of non-text objects such as images and URLs ...
