In this work we address the problem of Language identification (LI) on short segments of text. The central idea is to compute the entropy of a document in different contexts and assign it to the category where the entropy is maximal. Only word distributions are needed for the task, no other training is done. For LI the contexts are the languages, and classification is done by just evaluating th...

SEMAMO (SEmantic MArket MOnitoring) is a research project seeking to make use of the increasingly growing information available at Web-based sales and marketing channels for continuous market research. Assuming that online channels indeed mirror salient market developments faithfully, SEMAMO implements a nearly fully automatic adaptive data capture and analysis process delivering customer-defin...

User networks are beginning to be increasingly difficult to manage because of the large volume of information which is circulated within them. For example, in the Yahoo!Answers network, the large number of questions makes the identification of an expert, who would be the most suited to answer a question, a long-lasting process (currently this process is semi-automatic). This paper proposes an a...

Corpus resocialization can be achieved through digital revitalizing, i.e., making a corpus available for new users with new uses. We propose a semi-automatic identification of spatial and temporal markers that make up metadata for localized documents. Metadata is then exploited by concrete applications in environments for tourism and teaching.

We present our ongoing work towards using the concept of transactivity [1] for automatically assessing learning of students working together in a collaborative setting. Transactive segments of student dialogue are proposed as useful components of conversation summaries generated for instructors. Experimental evaluation of this hypothesis shows promising results. Further, initial results are pre...

Oak trees cover a wide range of forests in Iran and most of them are located in Kohgiloye and Boyer-Ahmad province (K.B). The high tannin is one of the anti-nutritional characteristics of acorn for domestic animal. Wide range of gut microorganisms could tolerate tannin and reduce it by producing tannase enzyme. This study was carried out to isolate and identify the tannin resistance bacteria (t...

introduction: hearing loss from birth up to the age of 3 years has a negative effect on speech/language development and results in sensory, cognitive, emotional, and academic defects in adulthood by causing delayed development of communicative-linguistic abilities. the present study was performed in order to assess the effect of early intervention on language development in persian children age...

this paper extends the sequential learning algorithm strategy of two different types of adaptive radial basis function-based (rbf) neural networks, i.e. growing and pruning radial basis function (gap-rbf) and minimal resource allocation network (mran) to cater for on-line identification of non-linear systems. the original sequential learning algorithm is based on the repetitive utilization of s...
