Effectively and efficiently supporting crowd-enabled databases via NoSQL paradigms
2013
In this paper we provide an overview of the Hints From the Crowd (HFC) project, whose main goal is to build a NoSQL database system for large collections of product reviews; the database is queried by expressing a natural language sentence; the result is a list of products ranked based on the relevance of reviews w.r.t. the natural language sentence. The best ranked products in the result list can be seen as the best hints for the user based on crowd opinions (the reviews). The HFC prototype has been developed as a web application, independent of the particular application domain of the collected product reviews. Queries are performed by evaluating a text-based ranking metric for sets of re…

IMPLICACIONES DEL USO DE BUSCADORES EN EL COMPORTAMIENTO DE COMPRA ONLINE / IMPLICATIONS OF THE SEARCH ENGINES USE IN THE ONLINE SHOPPING BEHAVIOUR
2009
El objetivo del presente trabajo es analizar los factores que influyen en el uso de buscadores y su incidencia en el comportamiento de compra en Internet. El análisis de resultados obtenidos a partir de una muestra representativa de 485 compradores por Internet españoles, pone de manifiesto que los consumidores que consideran la comodidad, reducciones de precio y amplitud de surtido como motivaciones relevantes para realizar compras online presentan una mayor predisposición al uso de buscadores en la realización de sus compras virtuales. La experiencia como internauta y como comprador en Internet son factores que influyen negativamente en el uso de buscadores para la realización de compras …

Informazione biomedica su Internet e motori di ricerca. Risultati di un trial di un anno
2004
The internet is a communication medium and content distributor that provide information in the general sense but it could be of great utility regarding as the search and retrieval of biomedical information. Search engines represent a great deal to rapidly find information on the net. However, we do not know whether general search engines and meta-search ones are reliable in order to find useful and validated biomedical information. The aim of our study was to verify the reproducibility of a search by key-words (pediatric or evidence) using 9 international search engines and 1 meta-search engine at the baseline and after a one year period. We analysed the first 20 citations as output of each…
«Lex Google»: Copyright Law and Internet Providers, Future Enemies or Allies?
2013
The German Federal Parliament is discussing the approval of the so-called “Lex Google” which will amend the German Copyright Act and provide for a number of improvements to the management of copyrighted content by Internet Service Providers. This paper focuses on the advantages and disadvantages linked to the diffusion of copyrighted content over the Internet and suggests that the Lex Google would benefit from taking better into account E-Commerce rules and ECJ case-law on Internet Service Providers.
On the evolution of monopoly pricing in Internet-assisted search markets
2014
This study examines the evolution of prices in markets with Internet price-comparison search engines. The empirical study analyzes laboratory data of prices available to informed consumers, for two industry sizes and two conditions on the sample (complete and incomplete). Distributions are typically bimodal. One of the two modes of distribution, corresponding to monopoly pricing, tends to attract such pricing strategies increasingly over time. The second one, corresponding to interior pricing, follows a decreasing trend. Monopoly pricing can serve as a means of insurance against more competitive (but riskier) behavior. In fact, experimental subjects who initially earn low profits due to int…
P-FCM: a proximity-based fuzzy clustering for user-centered web applications
2003
Abstract In last years, the Internet and the web have been evolved in an astonishing way. Standard web search services play an important role as useful tools for the Internet community even though they suffer from a certain difficulty. The web continues its growth, making the reliability of Internet-based information and retrieval systems more complex. Nevertheless there has been a substantial analysis of the gap between the expected information and the returned information, the work of web search engine is still very hard. There are different problems concerning web searching activity, one among these falls in the query phase. Each engine provide an interface which the user is forced to le…
CitySearcher: A City Search Engine For Interests
2017
We introduce CitySearcher, a vertical search engine that searches for cities when queried for an interest. Generally in search engines, utilization of semantics between words is favorable for performance improvement. Even though ambiguous query words have multiple semantic meanings, search engines can return diversified results to satisfy different users' information needs. But for CitySearcher, mismatched semantic relationships can lead to extremely unsatisfactory results. For example, the city Sale would incorrectly rank high for the interest shopping because of semantic interpretations of the words. Thus in our system, the main challenge is to eliminate the mismatched semantic relationsh…
Yksityisyys ja luottamus hakukoneiden käytössä
2016
Tämä tutkimus käsittelee yksityisyyden ja luottamuksen merkitystä hakukoneissa. Tämä on tärkeää, sillä hakukoneista on muodostunut ihmisten pääsääntöinen tiedon lähde. Näin ollen hakukoneiden yleistyminen on johtanut siihen, että käyttäjistä kerätään yhä enemmän henkilökohtaisia tietoja. Tämän ansiosta käyttäjille on noussut hakukoneista paljon yksityisyyshuolia ja sitä kautta myös luottamus voi rikkoutua. Tämä tutkimus on toteutettu kirjallisuuskatsauksena ja pyrkii vastaamaan tutkimuskysymykseen: mitä käyttäjän yksityisyys ja luottamus tarkoittavat hakukoneiden käytön yhteydessä? Tutkimuksen tulosten mukaan käyttäjien tietoisuuden parantamisella voidaan vaikuttaa sekä kokemukseen yksityis…
