We propose XIR-Linear, a method for efficiently evaluating linear path expressions (LPEs) on large-scale heterogeneous XML documents using information retrieval (IR) techniques. LPEs are the primary form of XPath queries, and their evaluation techniques have been researched actively. XPath queries in their general form are partial match queries, and these queries are particularly useful for sea...

This paper aims at integrating data envelopment analysis (DEA) and analytic hierarchy process (AHP) to evaluate the economic development achieved by local governments in China. Since most similar evaluations are multi-objection problems, which both DEA and AHP are capable of solving, the integration of these two approaches is shown to be even more powerful. The proposed integrated DEA/AHP model...

A slowly moving foreground with an orthogonally moving background can induce self-motion perception in the same direction as the foreground motion (inverted vection; [Vision Research 40 (2000) 2915]). In the present study, we investigate the effect of sustained gaze deviation on inverted vection. We hypothesized that gaze deviation affects eye-movement information registered in the perceptual s...

We address the problem of large scale image search, for which many recent methods use a bag-of-features image representation. We shows the sub-optimality of such a representation for matching descriptors and derive a more precise representation based on 1) Hamming embedding (HE) and 2) weak geometric consistency constraints (WGC). HE provides binary signatures that refine the matching based on ...

The purpose of this article is to characterise the production of postverbal subjects in two ICLE subcorpora (Italian and Spanish). The question has been dealt with before in the literature with emphasis on the production of ungrammatical inversion structures in L2 English of speakers from a variety of L1s, but in quite a scattered, unsystematic and rather intuitive fashion. Our approach seeks t...

In this paper, we propose a stand-alone mobile visual search system based on binary features and the bag-ofvisual words framework. The contribution of this study is three-fold: (1) We propose an adaptive substring extraction method that adaptively extracts informative bits from the original binary vector and stores them in the inverted index. These substrings are used to refine visual word-base...

A power system is modeled by an interaction form, the solution of which is called a settlement. By stability we mean the existence of some settlement for any preference profile. Like in other models of power structure, instability is equivalent to the existence of a cycle. Structural properties of the system like maximality, regularity, superadditivity, subadditivity and exactness are defined a...

The aim of the present study was to examine (a) if athletes’ moral judgment is affected by sport type, the level of competition – in terms of the league in which one competes – and regular playing position, and (b) possible relations between moral judgment and the overall years of athletic experience, self-perception of sport ability, and achievement goal orientations. The sample comprised 170 ...

More and more documents are stored in semistructured formats like XML. In contrast to traditional information retrieval, the documents can become quite large, and it is often desirable to retrieve not complete documents, but isolated elements that satisfy an information need. To make this possible, the index structures from traditional information retrieval must be adapted to semistructured doc...
