  • Introduction: Nowadays, p-dichlorobenzene (paradichlorobenzene, 1,4-dichlorobenzene) is becoming more popular than naphthalene as a moth repellant (insecticide) worldwide. The discrimination between p-dichlorobenzene and naphthalene is usually difficult only by their smells and their appearances. However, specific gravities of their crystals are different; they are 1.152 and 1.5 for naphthalene and p-dichlorobenzene, respectively.

  • Steiner symmetrization, one of the simplest and most powerful symmetrization processes ever introduced in analysis, is a classical and very well-known device, which has seen a number of remarkable applications to problems of geometric and functional nature. Its importance stems from the fact that, besides preserving Lebesgue measure, it acts monotonically on several geometric and analytic quantities associated with subsets of Rn. Among these, perimeter certainly holds a prominent position.

  • We present results of two methods for assessing the event profile of news articles as a function of verb type. The unique contribution of this research is the focus on the role of verbs, rather than nouns. Two algorithms are presented and evaluated, one of which is shown to accurately discriminate documents by type and semantic properties, i.e. the event profile. The initial method, using WordNet (Miller et al. 1990), produced multiple cross-classification of articles, primarily due to the bushy nature of the verb tree coupled with the sense disambiguation problem. ...

  • This paper describes an approach to utilizing term weights for sentiment analysis tasks and shows how various term weighting schemes improve the performance of sentiment analysis systems. Previously, sentiment analysis was mostly studied under data-driven and lexicon-based frameworks. Such work generally exploits textual features for fact-based analysis tasks or lexical indicators from a sentiment lexicon. We propose to model term weighting into a sentiment analysis system utilizing collection statistics, contextual and topicrelated characteristics as well as opinionrelated properties.

  • The paper describes a novel computational tool for multiple concept learning. Unlike previous approaches, whose major goal is prediction on unseen instances rather than the legibility of the output, our MPD (Maximally Parsimonious Discrimination) program emphasizes the conciseness and intelligibility of the resultant class descriptions, using three intuitive simplicity criteria to this end. We illustrate MPD with applications in componential analysis (in lexicology and phonology), language typology, and speech pathology. ...

  • A new approach of predicting structural classes of protein domain sequences is presented in this paper. Besides the amino acid composition, the composition of several dipeptides, tripeptides, tetrapeptides, pentapeptides and hexapeptides are taken into account based on the step-wise discriminant analysis. The result of jackknife test shows that this new approach can lead to higher pre-dictive sensitivityand specificityfor reduced sequence similaritydatasets.

  • This paper presents a predicate-argument structure analysis that simultaneously conducts zero-anaphora resolution. By adding noun phrases as candidate arguments that are not only in the sentence of the target predicate but also outside of the sentence, our analyzer identifies arguments regardless of whether they appear in the sentence or not. Because we adopt discriminative models based on maximum entropy for argument identification, we can easily add new features. We add language model scores as well as contextual features.

  • ‘Professions’ have been subject to a variety of theoretical schema that attempt to identify their unique characteristics or traits: the features that can be regarded as the basis for the discrimination between forms of occupational organization and control that are professional and those that are not (Saks, 1983; Abbott, 1988). This elaboration of the essential traits of professions is more than a professional discourse.

  • The most unfair criticism of business folks is that they are just “marketers,” somewhat of a negative label in the tech sector. I think marketing gets a bad rap. In MBA terms, there are four Ps that define marketing: product, price, placement, and promotion. Defining the product and price is a creative process. The goal is to develop a product idea—sold for a profit—that matches the needs of the targeted customer. Research, analysis, and creative work are necessary in order to succeed.

  • Nowadays, huge amount of multimedia data are being constantly generated in various forms from various places around the world. With ever increasing complexity and variability of multimedia data, traditional rule-based approaches where humans have to discover the domain knowledge and encode it into a set of programming rules are too costly and incompetent for analyzing the contents, and gaining the intelligence of this glut of multimedia data. The challenges in data complexity and variability have led to revolutions in machine learning techniques.
