There is an uptake of organizations’ involvement in collaborative organizational structures (COS). Consistent with the resource-centric views of the firm, we suggest that the COS members need to contribute their managed IT competencies to their COS, whose synergies would create COS IT competencies. We suggest three key IT competencies for COS: proactive top management decision synergy, collabor...

In this paper, we investigate the phonological and phonetic markers of focus and topic intonation in Greek. We have found that both focus and topic are marked by phrasing, type of pitch accent and boundary tone. One difference between the two is that, on the one hand, focus deletes a boundary after the focus word and de-accents all following words. On the other hand, topicalization creates an I...

In the context of information retrieval, we propose here to merge in a single mathematical framework: the Boolean model, the vector space model, and passage retrieval in a single mathematical framework based on signal theory. In this framework, we define the weight wd,t of the term t in the document d not as a number, but as a function.

We introduce a list of Arabic multiword expressions (MWE) collected from various dictionaries. The MWEs are grouped based on their syntactic type. Every constituent word in the expressions is manually annotated with its full context-sensitive morphological analysis. Some of the expressions contain semantic variables as place holders for words that play the same semantic role. In addition, we ha...

We present a transition-based system that jointly predicts the syntactic structure and lexical units of a sentence by building two structures over the input words: a syntactic dependency tree and a forest of lexical units including multiword expressions (MWEs). This combined representation allows us to capture both the syntactic and semantic structure of MWEs, which in turn enables deeper downs...

This paper summarizes the preliminary results of an ongoing survey on multiword resources carried out within the IC1207 Cost Action PARSEME (PARSing and Multi-word Expressions). Despite the availability of language resource catalogs and the inventory of multiword datasets on the SIGLEX-MWE website, multiword resources are scattered and difficult to find. In many cases, language resources such a...

'lhe Policy, Research, and Exterral Affairs Complex distributes PRE Working Papers to dissemninate the findings of work in progress and to encourage the exchange of ideas among Bank suaff and all others interested in development issues. These papers carry the names of the authors, reflect only their views, and should be used and cited accardingly. The findings, interpretations, and conclusions ...

We deal with syntactic identification of occurrences of multiword expression (MWE) from an existing dictionary in a text corpus. The MWEs we identify can be of arbitrary length and can be interrupted in the surface sentence. We analyse and compare three approaches based on linguistic analysis at a varying level, ranging from surface word order to deep syntax. The evaluation is conducted using t...

The support vector machine (SVM) is a wellestablished and accurate supervised learning method for the classification of data in various application fields. The statistical learning task – the so-called training – can be formulated as a quadratic optimization problem. During the last years the decomposition algorithm for solving this optimization problem became the most frequently used method fo...

Incorporating semantic information in the Statistical Machine Translation (SMT) framework is starting to gain some popularity in both the semantics and translation communities. In this paper, we present encouraging results obtained from experiments conducted on English to Arabic SMT system using static, dynamic, and hybrid integration of fine-grained Multiword Expression (MWE). We achieve an im...
