The objective of this paper is to describe the implementation of text mining grid services for Aîuri Project, which is a framework that includes a friendly user interface, data and text mining tasks, database access and a visualization tool integrated with various grid environments. The focus is the development and test of components for analysis and evaluation of unstructured data into distinc...

Item reviews are a valuable source of information for potential buyers, who are looking for information on a product’s attributes before making a purchase decision. This search of information is often hindered by overwhelming numbers of available reviews, as well as low-quality and noisy content. While a significant amount of research has been devoted to filtering and organizing review corpora ...

Traditional approaches to semantic relatedness are often restricted to text-based methods, which typically disregard other multimodal knowledge sources. In this paper, we propose a novel image-based metric to estimate the relatedness of words, and demonstrate the promise of this method through comparative evaluations on three standard datasets. We also show that a hybrid image-text approach can...

The Israeli Kibbutz movement is a voluntary cooperative based on equality, mutual assistance, partnership, and common ownership of property. It is one of the last socialist experiments that successfully survived for most of the twentieth century. How did a voluntary egalitarian institution exist in a more capitalist environment? What level of equality can be sustained as an equilibrium? I study...

This paper describes the building of a valency lexicon of Arabic verbs using a morphologically and syntactically annotated corpus, the Prague Arabic Dependency Treebank, as its primary source. We present the theoretical account on valency developed within the Functional Generative Description theory. We apply the framework to Arabic and discuss various valency-related phenomena with respect to ...

In this paper, we present MDSWriter, a novel open-source annotation tool for creating multi-document summarization corpora. A major innovation of our tool is that we divide the complex summarization task into multiple steps which enables us to efficiently guide the annotators, to store all their intermediate results, and to record user–system interaction data. This allows for evaluating the ind...

Announcements at railway stations are a major information source for passengers. In order to ensure high intelligibility, the traditional solution is to use recorded prompts with “slot filling” of variable data. If a data type (e.g. train name) changes new recordings have to be made. Even with careful design the quality of the system will gradually deteriorate due to change of the voice of the ...

In this paper we present LeXFlow, a web application framework where lexicons already expressed in standardised format semiautomatically interact by reciprocally enriching themselves. LeXFlow is intended for, on the one hand, paving the way to the development of dynamic multi-source lexicons; and on the other, for fostering the adoption of standards. Borrowing from techniques used in the domain ...
