Business Constraints Integration in a Search Engine Optimization Fuzzy Decision Support System

2017

The Internet has dramatically changed the way companies can reach their clients. Henceforth, to develop their business online, companies have to drive qualified traffic to their website. For this, their website must be visible in the first pages of search engine results. Search Engine Optimization (SEO) permits the improvement of the position of a website on the search engines results pages. However, the practice of SEO is complex, and results are uncertain, because search engines do not communicate much about their ranking methods. Moreover, this activity takes time, and requires the implementation of modifications that can alter the visual appearance of the webpages. This paper proposes a…

Rough Set Theory for Supporting Decision Making on Relevance in Browsing Multilingual Digital Resources

2017

Browsing digital library (DL) collections seems to pose a challenge for a user owning to the number of factors like for instance, operability of the system, interface readability or clarity, and retrieval efficiency directly related to it, or the number of digital items within the user’s domain. However, when it comes to searching for an item in a foreign language to the user, the number of the factors arises even more which translates proportionally to the growing number of clicks aimed to retrieve the target item. Such a procedure usually leads to disheartening the user from browsing the digital collections. Our study into the user’s behavior interacting with multilingual DL system is set…

Computer-assisted clinical diagnosis in the official European union languages

2016

eHealth services integrate Web Information Retrieval and Intelligent Medical Decision Support for health care professionals based on the range of possible symptoms which a patient reports. However, many symptoms like high temperature, fever, or headache, are ambiguous in terms of suggesting wide variety of possible patient's conditions to the GP, while other symptoms are mutually dependant, which again can be misleading to make an accurate diagnosis. On the other hand, doctor's up-to-date knowledge on the medicaments, drugs, active medical substances included, anticipated range of diseases relating to the symptoms reported, and the most reliable pharmaceutical manufacturers, are of the grea…

Information retrieval in digital documents : a variation patterns of procedural execution

2013

The research activity of information on the internet has become common in our daily life. Despite this fact, it still raises many problems for the user who does not find the information they want or is lost to the amount of information available. This study aims at testing a new patented preview device, enabling users to browse and view pages in depth. The task is to find a target apartment with one or more specific criteria in a real estate agency designed website. Several conditions were tested. The “usual” condition with the classic search features, page by page, the other "transparent" condition which enables you to preview selected pages and select only relevant pages. We are intereste…

Suitability of a content-based retrieval method in astronomical image databases

1996

Abstract Indexing and retrieval methods based on the image content are required to effectively use information from large repositories of digital images. Usually, the way to search for data and images in astronomical archives is via textual queries expressed in terms of constraints on observation parameters. In this paper we present a method for automatic extraction of images by using shape descriptions based on local symmetry. The proposed indexing methodology has been developed and tested inside JACOB, a prototypal system for content-based video database querying.

Technological Drivers and Sociocultural Change

2019

In this chapter, the suggestion is made that the relevance and timeliness of the concept of digital family is owing to certain advances in personal communication technologies that, together with wider social changes in the developed world, facilitate people’s participation in a digital society. First, we take a look at recent technological advancements in personal communication technology and social media applications, after which we examine more in-depth some of the major sociocultural transformations to have paved way for the emergence and rise of the digital family.

Grover’s Algorithm with Errors

2013

Grover’s algorithm is a quantum search algorithm solving the unstructured search problem of size n in \(O(\sqrt{n})\) queries, while any classical algorithm needs O(n) queries [3].

Understanding Quantum Algorithms via Query Complexity

2017

Query complexity is a model of computation in which we have to compute a function $f(x_1, \ldots, x_N)$ of variables $x_i$ which can be accessed via queries. The complexity of an algorithm is measured by the number of queries that it makes. Query complexity is widely used for studying quantum algorithms, for two reasons. First, it includes many of the known quantum algorithms (including Grover's quantum search and a key subroutine of Shor's factoring algorithm). Second, one can prove lower bounds on the query complexity, bounding the possible quantum advantage. In the last few years, there have been major advances on several longstanding problems in the query complexity. In this talk, we su…

DEFECT THEOREMS FOR TREES

2000

We generalize different notions of a rank of a set of words to sets of trees. We prove that almost all of those ranks can be used to formulate a defect theorem. However, as we show, the prefix rank forms an exception.
