This is the second time we participate in TREC Blog Track. There are three main tasks in the track, relevant finding task, opinion finding task and polarity task. In this year, we use multi-field relevance ranking in relevant finding task; and in opinion finding task, we focused on the combination of relevance score and opinionate score use a unified generation model; in polarity task, we devel...

introduction. the assessment of learning needs is one of the basic stages in education which leads to a change in medical education curriculum. such assessment can be conducted based on different reasons. therefore it should be defined, and the methods of application of the findings must be analyzed. one of the known methods of need assessment is the analysis of the differences between the pres...

Turning oV a Wxation point, typically for 200 ms, before the onset of a peripheral target substantially reduces saccadic reaction times. This facilitatory eVect generated by an inserted temporal gap between Wxation oVset and the target appearance is called the “gap” eVect [J Opt Soc Am 57:1030–1033, 1967]. We show that the gap reduces the initial latency of both saccades and manual pointing in ...

A common notion of vision, consistent with this excerpt from the first paragraph of David Marr’s seminal book [1], is gained by considering the predicament of a person with a searchlight placed in a pitch-dark room full of unfamiliar furniture. One would hope that, by swinging the beam around, the observer will be able to recognize the objects present in the room (a cat here, an aquarium there,...

A computational complexity gap, captured in the definition of one-way functions, is a necessary and sufficient condition for much of modern cryptography. Loosely speaking, one-way functions are functions that are easy to compute but hard to invert (in an average-case sense). The existence of one-way functions implies that P is different than NP , which means that such a complexity gap is only w...

This thesis work presents a novel framework for Opinion Summarization. This task consist in the extraction of parts of a opinionated text that represents the main opinions and build a legible and human-readable opinion summary. This task is very difficult and it involves several methods related to Opinion Mining, Natural Language Processing, Machine Learning, Information Retrieval and other are...

Analysis of opinions, known as opinion mining or sentiment analysis, has attracted a great deal of attention recently due to many practical applications and challenging research problems. In this article, we study two important problems, namely, opinion lexicon expansion and opinion target extraction. Opinion targets (targets, for short) are entities and their attributes on which opinions have ...

background: the faculty of medical sciences, university of zahedan implemented the objective structured clinical examination (osce) in the final examination during the 2003–2004 academic year. simultaneously, the pediatric department initiated faculty and student training, and instituted the osce as an assessment instrument during the pediatric clerkship in year 5. the study set out to explore ...

In this article, we propose to evaluate the lexical similarity information provided by word representations against several opinion resources using traditional Information Retrieval tools. Word representation have been used to build and to extend opinion resources such as lexicon, and ontology and their performance have been evaluated on sentiment analysis tasks. We question this method by meas...
