Navigational Rule Derivation: An algorithm to determine the effect of traffic signs on road networks
(2016-11-17)
[Abstract] In this paper we present an algorithm to build a road network map enriched with traffic rules such as one-way streets and forbidden turns, based on the interpretation of already detected and classified traffic ...
Efficient and Compact Representations of Some Non-canonical Prefix-Free Codes
(Springer, 2016-09-21)
[Abstract] For many kinds of prefix-free codes there are efficient and compact alternatives to the traditional tree-based representation. Since these put the codes into canonical form, however, they can only be used when ...
GraCT: A Grammar Based Compressed Representation of Trajectories
(Springer, 2016-09-21)
[Abstract] We present a compressed data structure to store free trajectories of moving objects (ships over the sea, for example) allowing spatio-temporal queries. Our method, GraCT, uses a k2k2 -tree to store the absolute ...
Compact Trip Representation over Networks
(Springer, 2016-09-21)
[Abstract] We present a new Compact Trip Representation ( CTRCTR ) that allows us to manage users’ trips (moving objects) over networks. These could be public transportation networks (buses, subway, trains, and so on) where ...
Efficient Representation of Multidimensional Data over Hierarchical Domains
(Springer, 2016-09-21)
[Abstract] We consider the problem of representing multidimensional data where the domain of each dimension is organized hierarchically, and the queries require summary information at a different node in the hierarchy of ...
Towards a Non-Functional Requirements Discovery Approach for Persuasive Systems
(Association for Computing Machinery, 2020-03-30)
[Abstract] A number of software systems that attempt to help people achieve behavior change have been proposed in various domains such as health and wellness. However, sometimes, such systems have failed to provide a ...
Improved Compressed String Dictionaries
(ACM, 2019-11-03)
[Abstract] We introduce a new family of compressed data structures to efficiently store and query large string dictionaries in main memory. Our main technique is a combination of hierarchical Front-coding with ideas from ...
Succinct Data Structures in the Realm of GIS
(MDPI, 2021)
[Abstract] Geographic Information Systems (GIS) have spread all over our technological environment in the last decade. The inclusion of GPS technologies in everyday portable devices along with the creation of massive ...
Tool for SPARQL Querying over Compact RDF Representations
(MDPI, 2021)
[Abstract] We present an architecture for the efficient storing and querying of large RDF datasets. Our approach seeks to store RDF datasets in very little space while offering complete SPARQL functionality. To achieve ...
Towards a Semi-Automated Data-Driven Requirements Prioritization Approach for Reducing Stakeholder Participation in SPL Development
(MDPI, 2021)
[Abstract] Requirements prioritization (RP), part of Requirements engineering (RE), is an essential activity of Software Product-Lines (SPL) paradigm. Similar to standard systems, the identification and prioritization of ...
