Our experiments in TRECVID 2011 include participation in the semantic indexing and known-item search tasks. In the semantic indexing task we implemented linear and SVM-based classifiers on different low-level visual features extracted from the keyframes. In addition to the main keyframes provided by NIST, we also extracted and analysed additional frames from longer shots. The classifiers were f...

Most existing cross-domain recommendation algorithms focus on modeling ratings, while ignoring review texts. The review text, however, contains rich information, which can be utilized to alleviate data sparsity limitations, and interpret transfer patterns. In this paper, we investigate how to utilize the review text to improve cross-domain collaborative filtering models. The challenge lies in t...

In this work we explore the capability of audiovisual parameters (such as fundamental frequency, rhythm, head motion or facial expressions) to discriminate among different dramatic attitudes. We extract the audiovisual parameters from an acted corpus of attitudes and structure them as frame, syllable, and sentence-level features. Using Linear Discriminant Analysis classifiers, we show that sent...

Let T be a text over a xed alphabet A. Then an automaton can be created in a linear time that accepts all substrings that occur in text T . The ratio of the size of the implementation of this automaton (factor automaton, DAWG) and of the input text is in usual cases 14:1 . This paper shows a method of implementing DAWG that reduces this ratio down to 4:1 while preserving good qualities of the a...

This paper presents a logical formalization of a set 20 semantic categories related to opinion, emotion and sentiment. Our formalization is based on the BDI model (Belief, Desire and Intetion) and constitues a first step toward a unifying model for subjective information extraction. The separability of the subjective classes that we propose was assessed both formally and on two subjective refer...

In this paper, we prove the operator inequalities as follows: Let [Formula: see text] be positive operators on a Hilbert space with [Formula: see text] and [Formula: see text]. Then for every positive unital linear map Φ, [Formula: see text] and [Formula: see text] Moreover, we prove Lin's conjecture when [Formula: see text].

morrison’s song of solomon could be viewed as a paragon of trauma fiction. since no narrative of trauma can be told in a linear way, morrison tries to depict the overwhelming power of trauma through a non-linear narrative, episodic delivery, and flashbacks. accordingly, the readers are compelled to concoct the disjointed and fragmented memories in order to solve the riddle of the text, in which...
