La sémantique sensorielle peut-elle être autre chose qu’une sémantique expérimentale ?

2017

International audience; [Objectifs et problématique] La question au centre de la proposition est celle de savoir quel(s) cadre(s) sémantique(s) théorique(s) est / sont le(s) mieux à même de rendre justice aux contraintes génériques qui pèsent sur les terminologies sensorielles – à commencer, ici, par la terminologie œnologique. Il s’agit en effet de tenir compte de deux aspects particuliers : d’une part la dimension expérientielle de ces termes (Dubois 2009) – où expérience doit être entendu au sens très concret de l’expérience de dégustation – et, d’autre part, la dimension éminemment subjective de ces expériences que la recherche d’une intersubjectivité partagée – comme sous-bassement déf…

What really causes large price changes?

2003

We study the cause of large fluctuations in prices in the London Stock Exchange. This is done at the microscopic level of individual events, where an event is the placement or cancellation of an order to buy or sell.

Even for the most liquid stocks there can be substantial gaps in the order book, corresponding to a block of adjacent price levels containing no quotes. When such a gap exists next to the best price, a new order can remove the best q…

HTTP-level e-commerce data based on server access logs for an online store

2020

Abstract Web server logs have been extensively used as a source of data on the characteristics of Web traffic and users’ navigational patterns. In particular, Web bot detection and online purchase prediction using methods from artificial intelligence (AI) are currently key areas of research. However, in reality, it is hard to obtain logs from actual online stores and there is no common dataset that can be used across different studies. Moreover, there is a lack of studies exploring Web traffic over a longer period of time, due to the unavailability of long-term data from server logs. The need to develop reliable models of Web traffic, Web user navigation, and e-customer behaviour calls for …
